DETAILED DESCRIPTION OF THE INVENTION
Referring in detail now to the drawings wherein similar parts of the invention
are identified by like reference numerals, there is seen the marking device of
the present invention, generally illustrated as 10. FIGS. 1-31 is one embodiment
of the present invention, and FIGS. 32-39 is another embodiment of the present
invention. Initially addressing the embodiment depicted in FIGS. 1-31, the
marking device 10 comprises a casing or housing 12 having a slotted opening 14
and an opening 16. A coiled tape, generally illustrated as 18, is rotatably
disposed within or to the inside of the housing 12 such that as tape 20 is
uncoiled from the coiled tape 18, the tape 20 may be extended or retracted
through the slotted opening 14 in the housing 12. The coiled tape 18 is
rotatably mounted on shaft 13. The tape 20 has a tab end 22 secured to an end
thereof. At least one linkage engaging member, generally illustrated as 24, is
engaged to and on the tape 20. Preferably a plurality of linkage engaging
members 24 is secured to the tape 20. The engaging member 24 may be any suitable
member, but is preferably a protruding lug 26 secured thereto as best shown in
FIG. 31. Alternatively, the lug 26 is formed in the tape 20 during
manufacturing, such as by indentation of the tape 20 (see FIG. 30). It is to be
understood that for purposes of the present invention as described in the
specification and as claimed in the claims, a lug 26 secured to the tape 20
(such as by solder weld, epoxy, etc.) is equivalent to the tape 20 having the
lug 26 inherently formed therein through indentation or the like.
A marker assembly, generally illustrated as 30, is disposed in the housing 12.
The marker assembly 30 comprises a bracket 32 secured to an inside wall of the
housing 12. The bracket 32 has an opening 34 (preferably square or rectangular
in geometry) wherethrough a shaft 36 (preferably also square or rectangular in
geometry) slidably passes such as to be capable of sliding up and down. A pin 38
passes through the head of the shaft 36, and a flanged washer member 40 is
slidably disposed on the shaft 36 underneath the pin 38. A spring member 42
helically surrounds the shaft 36 between the bracket 32 and the washer member
40. The spring member 42 is supported by the bracket 32 and biasingly engages
the washer member 40 to bias upwardly the shaft 36 such that when the top of the
shaft 36 is depressed, the shaft 36 is returned to its original posture when the
depression is released. A marker 44 is secured to the end of the shaft 36. The
marker 44 is preferably a consumable marker that may be formed from a variety of
materials such as crayon, ink pad, chalk, lead, soap stone or tailor's crayons.
Material of this type provide a highly visible mark which may be readily removed
from most items. When the shaft 36 is driven downwardly the marker 44 passes
through the opening 16 and deposits a mark 48 on an article or a substrate 50,
such as a piece of wood (see FIG. 21). The marker 44 may be of any suitable
shape, such as T-shaped as depicted in FIGS. 6, 7, 8 and 17, or square-shaped as
depicted in FIGS. 32 and 35.
A linkage assembly, generally illustrated as 54, is pivotably disposed within
the housing 12 such that when the engaging member 24 (i.e. lug 26) engages the
linkage assembly 54, the linkage assembly 54 engages and moves the marker
assembly 30 to drive the marker 44 through the opening 16 to deposit a mark 48.
The linkage assembly 54 comprises a spring biased generally L-shaped lever 58
mounted on a bearing 60 which is rotatably secured to a shaft 62. Lever 58 is
normally biased upwardly or clockwise (with respect to the view in FIG. 7) by a
spring 64 which is also engaged to the shaft 62. The spring 64 includes a pair
of arms 64a and 64b extending outwardly from a helical center 64c that
circumscribes the shaft 62. Arm 64b engages and contacts the lever 58 as
depicted in FIG. 7 and 17. Arm 64a engages an upper partition 65 which is
secured to an inside wall of the housing 12. A lower partition member 67 is also
secured to an inside wall of the housing 12, and is spaced from the upper
partition 65 to provide an opening 69 therebetween. Lever 58 is pivotably
disposed on the shaft 62 such that as the linkage engaging member 24 (i.e. lug
26) on the tape 20 contacts a beveled end 58e of the lever 58 (see FIGS. 24, 25
and 27) the lever 58 pivots about shaft in a clockwise direction as depicted in
FIGS. 7 and 25. A shaft 70 is conveniently secured to an inside wall of the
housing 12 generally in the opening 69 and/or between the partition 65 and 69,
and is spaced from coiled tape 18 such that as the tape 20 is uncoiled from or
off of coiled tape 18, the tape 20 loops over and passes around the shaft 70 in
order that each member 24 (lug 26) is capable of contacting the beveled end 58e
of the lever 58 to pivot the same clockwise with respect to the view in FIG. 7.
The linkage assembly 54 also includes a generally straight lever, generally
illustrated as 74, mounted on a bearing 76 which is rotatably secured to a shaft
78. The lever 74 is normally biased clockwise by the upwardly biased shaft 36.
More specifically, lever 74 has opposed ends 74a and 74b. End 74a is generally
biased upwardly by the upwardly biased shaft 36. By end 74a being biased
upwardly, a clockwise rotational motion with respect to the views in FIG. 7, 24
and 25 is placed on the lever 74, causing end 74b to be biased downwardly and
tending to rotate clockwise. End 74b tends to bias lever 58 counterclockwise,
opposite to the direction that spring 64 biases lever 58. As best shown in FIG.
24, before engaging member 24 (lug 26) engages the beveled end 58e of the lever
58, there is a steady state condition and "happy balance" among the marker
assembly 30, the lever 74, and the lever 58--spring 64 combination. As tape 20
is being uncoiled and pulled over shaft 70, eventually an engaging member 24
(lug 26) comes into contact with an end (more specifically the beveled end 58e)
of the lever 58. Such slidable contact and continual uncoiling of the tape 20
from the coiled tape 18 causes the engaging member 24 (lug 26) to slidably
contact the end 58e and pivotably rotate clockwise the lever 58, driving end 74b
upwardly (with the assistance of spring 64) and causing lever 74 to pivot
counterclockwise and drive spring biased shaft 36 downwardly, resulting in the
marker 44 depositing the mark 48 on a substrate 50 (all with respect to and as
best shown in FIG. 25). After the mark 48 has been deposited, the engaging
member 24 (lug 26) slips off of beveled end 58e and the inter-engaged
cooperating combination of the marker assembly 30/lever 74/lever 58- spring 64
returns to the steady-state, "happy balance" of FIG. 24 until a subsequent or
following engaging member 54 (lug 26) encounters the beveled-end 58e to start
the marking process again.
In operation of the marking device 10 depicted in FIGS. 1-31, the tab end 22 of
the tape 20 would be fixed on one edge of the article or substrate 50 to be
measured and serially marked (see FIG. 20) and the lower part of the marking
device 10 (i.e. more specifically the housing 12) would be positioned flushed
against the article such that the surface of the article to be marked supports
the marking device 10 and communicates with the opening 16. After the marking
device 10 is affixed and postured as such, the marking device 10 is manually
pulled slidably across the surface to be marked, causing the tape 20 to start
uncoiling from the coiled tape 18. When the first engaging member 24 (i.e. lug
26) passes over shaft 70 and slidably engages the beveled end 58e of the lever
58, lever 58 (with the assistance of spring 64) rotates clockwise which
simultaneously causes the lever 74 to pivot counterclockwise, all rotational
directions with respect to the view in FIGS. 24 and 25. As lever 74 rotates
counterclockwise, end 74a of lever 74 commences to drive spring biased shaft 36
downwardly until marker 44 contacts the article or substrate 50, causing the
deposition of the mark 48. After the mark 48 has been placed on the article or
substrate 50, the first engaging member 24 (i.e. lug 26) slidably passes off of
beveled end 58e and the combination of the marker assembly 30/lever 74/lever
58-spring 64 immediately returns to the steady-state posture depicted in FIG.
24. The marking device 10 is continually pulled slidably across the surface to
be marked (i.e. from left to right in FIG. 20) and the tape 20 continues to be
uncoiled from coiled tape 18. When the second engaging member 24 (i.e. lug 26)
passes over shaft 70 and slidably engages the beveled end 58e of the lever 58,
lever 58 (with the assistance of spring 64) again rotates clockwise and the
marking process (through actuation of the inter-engaging cooperating lever
75--marker assembly 30) is again repeated, causing the deposition of a second
mark 48. After the second engaging member 24 (i.e. lug 26) slips off or from
beveled end 58e, the cooperating combination of the marker assembly 30/lever
74/lever 58--spring 64 again returns to the steady-state posture depicted in
FIG. 24. The marking process can be repeated to deposit a third mark 48, a
fourth mark 48, and so on, until the marking device 10 reaches the end of the
article or substrate 50 as best shown in FIG. 20. As best shown in FIG. 21, the
resulting article or substrate 50 has a surface bearing a plurality of marks 48
which are spaced apart by a distance generally equal to the distance that the
engaging members 24 are spaced on the tape 20. Thus, if the engaging member 24
are spaced apart by one (1) foot on the tape 20, then the marks 48 are spaced
one (1) foot apart. It is obvious that the distance between engaging members 24
on the tape 20 may vary and not be the same, depending on desired results by the
user of the marking device 10. Typically, the deposed marks 48 on the surface of
the article or substrate are approximately the same distance.
Referring now to FIGS. 32-39 for another embodiment of the present invention,
the marker assembly 30 and the linkage assembly 54 are basically the same. The
lever 58 extends through opening 69 such that the beveled end 58e is on the
other side of the partitions 65 and 67. The engaging member 24 (i.e. lug 26) is
no longer placed on the tape, but is conveniently placed on a sprocketed wheel
member, generally illustrated as 100. Wheel member 100 has a circumference
defining a generally smooth outer surface 102 to which the engaging member 24
(lug 26) connects. The circumference also includes a protruding sprocket 104.
Wheel member 100 is rotatably mounted on a shaft 108. The other end of shaft 108
may be free or supported in aperture 110 of a bearing plate 112. Bearing plate
112 may be releasably secured to and between partition 65 and an end of the
housing 12 or to one of the side inside walls with bolts 114 (see FIG. 35).
Similarly, shaft 13 (which rotatably supports the coiled tape 18) may be free at
the end opposed to the end being supported by an inside side wall of the housing
12 or supported in aperture 118. A shaft 120 is rotatably supported on and by
the insides of the opposed side walls of the housing 12 as best shown in FIG.
34. The shaft 120 has a sprocket surface or member 122 keyed to or otherwise
mounted to the shaft 120. The sprocket member 122 is rotatably engaged to the
protruding sprocket 104 to move the same when shaft 120 turns. A biased roller
means, generally illustrated as 130, is disposed in the bottom of housing 12 for
biasing the tape 20 upwardly against roller 120 when the tape 20 passes
therebetween. Biased roller means 130 includes a roller 132 rotatably supported
by a frame 134 which is biased upwardly by a spring 136. The bottom of the frame
134 may have a tongue 600 (see FIG. 51) being vertically slidably supported
within a sleeve 700 which is connected to the bottom of the housing 12, and
spring 136 would bias the bottom of the frame 134 with its associated tongue 600
slidably moving up and down in the sleeve 700. The tape 20 slidably passes
between shaft 120 and biased roller 132. As the tape 20 is being pulled and
uncoiled from coiled tape 118 it frictionally passes against shaft 120 from the
biasing force of the biased roller 132. Such frictional passages causes shaft
120 to rotate. Sprocket member 122 rotates with shaft 120. When sprocket member
122 rotates, wheel 100 rotates from the meshing of sprocket 104 with sprocket
member 122. As wheel 100 rotates, the engaging member 24 (lug 26) comes in
contact with the beveled end 58e of the lever 58 and the marking process
commences. The gear or revolution ratio between the sprocket member 122/shaft
120 combination and the wheel 100 may be any ratio but is preferably one that
when the tape 20 is pulled twelve (12) inches or sixteen (16) inches the wheel
100 makes a full revolution and activates the marker assembly 30 through the
linkage assembly 54.
Referring now to FIGS. 40-51 for yet another embodiment of the present
invention, there is provided a magnetic strip 224, a magnetic sensor 155,
electrical power means (i.e. a battery 151), and an electronic solenoid 150, all
of which replace the engaging member 24 and the linkage assembly 54. More
specifically and referring to FIGS. 40-45, there is seen the magnetic strip 224
secured to the tape 20. Typically, there would be a plurality magnetic strips
224 spaced apart on the tape 20 at a distance that the marks 48 are to be spaced
apart on the substrate 50. A pair of magnetic sensor holders 156--156 are
secured to an inside wall of the housing 12. The holders 156--156 hold and
support a magnetic sensor 155 in close proximity to the opening 69 such that as
each magnetic strip 224 passes into the opening 69 (see FIG. 45), the magnetic
sensor 155 is close enough to each magnetic strip 224 to sense the same to
activate the electronic solenoid 150. A pair of battery holders 152--152 and a
pair of solenoid holders 157--157 are also secured to an inside wall of the
housing 12. The battery holders 152--152 are for holding and supporting the
battery 151 (i.e. an electrical power means), and the solenoid holders 157--157
are for holding the electronic solenoid 150 which is capable, when activated by
the battery 151/magnetic sensor 155, of operating and activating the marker
assembly 30 by depressing and driving the shaft 36 downwardly. Magnetic sensor
155 is electronically engaged to the battery 151 by conductor 900, and to
solenoid 150 by conductor 906. Solenoid 150 may be any of the well known state
of the art solenoids that is capable of depressing and driving shaft 36
downwardly. Similarly, magnetic sensor 155 may be any of the well known state of
the art magnetic sensors that is capable of sensing magnetically the magnetic
strips 224 and activating the solenoid 150 by closing the circuit with the
battery 151.
In operation of the marking device 10 depicted in FIGS. 40-46, the tab end 22 of
the tape 20 would be fixed on one edge of the article or substrate 50 to be
measured and serially marked (see FIG. 20) and the lower part of the marking
device 10 (i.e. more specifically the housing 12) would be positioned flushed
against the article such that the surface of the article to be marked supports
the marking device 10 and communicates with the opening 16. After the marking
device 10 is affixed and postured as such, the marking device 10 is manually
pulled slidably across the surface to be marked, causing the tape 20 to start
uncoiling from the coiled tape 18. When the first magnetic strip 224 passes over
the shaft 70 and activates the magnetic sensor 155, the electrical circuit
closes between the battery 151 and the solenoid 150 to cause the latter to drive
spring biased shaft 36 downwardly until marker 44 contacts the article or
substrate 50, causing the deposition of the mark 48. After the mark 48 has been
placed on the article or substrate 50, the first magnetic strip 224 has passed
out of opening 69 and away from the magnetic sensor 150, causing the latter to
open the electrical circuit between the battery 151 and the solenoid 150 for the
solenoid 150 to release the shaft 36 such that the spring 42 can drive the shaft
36 upwardly and release the marker 44 off of the substrate 50. The marking
device 10 is continually pulled slidably across the surface to be marked (i.e.
from left to right in FIG. 20) and the tape 20 continues to be uncoiled from
coiled tape 18. When the second magnetic strip 224 passes over shaft 70 and
activates the magnetic sensor 155, the operation is repeated again, causing the
deposition of a second mark 48. The marking process can be repeated to deposit a
third mark 48, a fourth mark 48, and so on, until the marking device 10 reaches
the end of the article or substrate 50 as best shown in FIG. 20. As best shown
in FIG. 21, the resulting article or substrate 50 has a surface bearing a
plurality of marks 48 which are spaced apart by a distance generally equal to
the distance that the magnetic strips 224 are spaced on the tape 20. Thus, if
the magnetic strips 224 are spaced apart by one (1) foot on the tape 20, then
the marks 48 are spaced one (1) foot apart. It is obvious that the distance
between magnetic strips 224 on the tape 20 may vary and not be the same,
depending on desired results by the user of the marking device 10. Typically,
the deposed marks 48 on the surface of the article or substrate are
approximately the same distance.
Referring now to FIGS. 47-51 for another embodiment of the present invention,
the marker assembly, the solenoid 150 and the battery 151 are basically the same
and located generally in the same location within the housing 12. The magnetic
sensor 155 is disposed on the other side of partition 65 and 67. Holders
156--156 may be secured to bearing plate 112 (see FIG. 47) or to an inside wall
of the housing 12 (see FIG. 43). The magnetic strip 224 is no longer on the
tape, but is conveniently placed on the sprocketed wheel member 100. The
operation of this embodiment of the invention is basically the same as that of
FIG. 32-39 in combination with the embodiment of FIGS. 40-46. More specifically,
as the tape 20 is being pulled and uncoiled from coiled tape 118 it frictionally
passes against shaft 120 from the biasing force of the biased roller 132. Such
frictional passages causes shaft 120 to rotate. Sprocket member 122 rotates with
shaft 120. When sprocket member 122 rotates, wheel 100 rotates from the meshing
of sprocket 104 with sprocket member 122. As wheel 100 rotates, the magnetic
strip 224 comes or passes in proximity to the magnetic sensor 155 and the
marking process commences. The gear or revolution ratio between the sprocket
member 122/shaft 120 combination and the wheel 100 may be any ratio but is
preferably one that when the tape 20 is pulled twelve (12) inches or sixteen
(16) inches the wheel 100 makes a full revolution and activates the marker
assembly 30 through the sensor 155/solenoid 150/battery 151 assembly.
Referring now to FIGS. 52-58 for yet another embodiment of the present
invention, the marker assembly 30 is basically the same as the embodiment
depicted in FIGS. 1-31. The linkage assembly 54 and tape 20 are similar to that
depicted in FIGS. 1-31 with some notable exceptions. The linkage assembly 54
additionally comprises a third lever member 503 pivotally secured to an inner
flange member 502 protruding from an inner wall of the housing 12. The shaft 62
is secured to the third lever 503, rather than the housing 12, as in the
previous embodiments. The bearing 60 is secured thereto and lever 58 is secured
to the bearing 60, such that lever 58 is pivotally coupled to the third lever
503. As previously mentioned, lever 58 is normally biased upwardly, or clockwise
with respect to the view depicted by FIG. 54, by the spring member 64 which is
disposed on the shaft 62. In this embodiment, as best shown in FIGS. 52 and 54,
lever 58 comprises a pointed end 58f. The lever 58 extends through the opening
69 such that pointed end 58f is on the other side of the partitions 65 and 67.
Additionally, the lever 503 is forwardly biased such that the lever 503
maintains a small amount of biasing force towards the upper partition member 65
(see FIG. 54). The spring 501, like spring 64, defines a structure comprising a
helical coil 503c, and a pair of arms 503a and 503b extending therefrom.
Therefore, forward bias is provided by the spring 501 acting on lever 503, and
clockwise bias (with respect to the view depicted by FIG. 54) is provided by
spring 64 acting on lever 58, thereby creating an action potential. In this
embodiment, the linkage is actuated by at least one linkage engaging aperture
500 disposed in the tape 20, and preferably, as mentioned above, a plurality of
such apertures 500 are disposed in the tape 20 at regular intervals (see FIGS.
56 and 57). The operation of the invention is basically the same as the
embodiment depicted in FIGS. 1-31, except for, as mentioned before, the linkage
assembly is actuated by the linkage engaging aperture 500. As best shown in
FIGS. 52 and 54, the tape 20 is uncoiled from the coiled tape 18. When the first
linkage engaging aperture 500 passes over shaft 70 and engages the pointed end
58f of the lever 58, lever 58 (with the assistance of the action potential
created by the clockwise bias of spring 64) rotates clockwise which
simultaneously causes the lever 74 to pivot counterclockwise (all rotational
directions with respect to FIGS. 52 and 54). The pointed end 58f of the lever 58
is forced into the linkage engaging aperture 500 by the spring biased lever 503.
As lever 74 rotates counterclockwise, end 74a of lever 74 commences to drive
spring biased shaft 36 downwardly until marker 44 contacts the article or
substrate 59, causing the deposition of the mark 48. After the mark 48 has been
placed on the article or substrate 50, the linkage engaging aperture 500
slidably passes off of the pointed end 58f of lever 58 and the combination of
the marker assembly 30/lever 74/lever 58--spring 64/lever 503--spring 501
immediately returns to the stead-state posture depicted in FIG. 54. The process
repeats as tape 20 is uncoiled from coiled tape 18 and linkage engaging
apertures 500 engage the linkage assembly, disposing marks 48 on the article or
substrate 50. As previously mentioned, the resulting article or substrate 50 has
a surface bearing a mark 48, or a plurality of marks 48--48 (see FIG. 55) which
are spaced generally equal to the intervals of linkage engaging apertures 500.
In another embodiment of the invention depicted in FIGS. 58-61, the end 58 of
the lever has a string 904 that runs around a post 903 (which is secured to one
of the walls, such as shown in FIG. 61) and is subsequently tied to the top of
the shaft of the marker. As the lever 56 is pulled or rotates, the string 904 is
simultaneously pulled causing the marker device to move up and down. Thus, lever
74 has been replaced by the combination of the string or line 904 and the post
903.
Referring now to FIGS. 62-66 for still another embodiment of the invention,
there is seen the marking device 10 having a similar structure to the embodiment
depicted in FIGS. 52-58. The embodiment of FIGS. 62-66 has modifications to both
the linkage assembly and the marking assembly. Like the embodiment of FIGS.
52-58, lever 503 is coupled to flange 502 and to lever 58 and lever 58 is
secured to bearing 60. Bearing 60 of lever 58 is slidably engaged to shaft 62.
Shaft 62 is secured to lever 503, such that shaft 62 is generally perpendicular
to lever 503. Another shaft 404 is secured to an inside wall of the housing 12
such that a positioning assembly, generally illustrated as 401, may slide
thereon. The positioning assembly comprises a selector lever member 400 and the
shaft member 404. The selector lever comprises an aperture 402 disposed therein
for slidably engaging the shaft member 404. A pair of arms 400A-400B are secured
to the selector lever such that the arms 400A-400B and the selector lever 400
define a structure that is generally U-shaped. Lever 58 is positioned between
the arms 400A-400B of the selector lever 400 such that lever 58 may be slidably
moved along shaft 62 of lever 503 by sliding the selector lever 400 in the
direction of the arrows C--C in FIG. 64. The lever 58 is fashioned to move in
this embodiment to allow the interval of marking with marker 44 to vary. To this
end, at least one linkage engaging aperture 500A is placed on tape 20, as shown
in FIG. 67 such that the linkage engaging aperture 500A is generally not in line
with the linkage engaging aperture 500. Stated alternatively, given by way of
example only, if linkage engaging aperture 500 is generally longitudinally
centered in tape 20, as shown in FIG. 67, then linkage engaging aperture 500A is
generally not centered, so that the interval of marks made by the linkage
assembly does not include a mark made for linkage engaging aperture 500 and
linkage engaging aperture 500A. Thus the interval for marks 48 placed on
substrate 50 (as shown in FIG. 62) may be chosen by sliding selector lever 400
such that the pointed end 58f of lever 58 lines up with linkage engaging
aperture 500A or another linkage engaging aperture, such as linkage engaging
aperture 500. It is to be understood that the tape 20 may comprise as many sets
of linkage engaging apertures 500-500A as necessary. The embodiment of the
marking device 10 in FIGS. 62-66 has a modified marking assembly 30 comprising a
first rod member 300 having a plurality of teeth 301 on an edge 301A and a
second rod member 302 having a plurality of teeth 303 on an edge 303A. The first
rod member 300 is situated in the housing such that a gear member 304 having an
aperture 305 is disposed on a shaft member 306 situated therebetween. The
plurality of teeth 301-303 of each rod member 300-302, respectively, mesh with
gear member 304 such that as one rod member 300 moves upward, (i.e. when moved
upward by lever 58 which is coupled thereto) the other rod member 302 moves
downward. The marker 44 is secured to the rod member 32 such that the marker may
pass through the opening 16 in the housing 12 and mark the substrate 50. A pair
of opposed rod retainers 310A-310B are secured to the housing 12 such that the
rod members 300-302 may slidably vertically move therein. The rod retainers
310A-310B each comprise a pair of apertures 311A and 311B wherethrough the rod
members 300-302 may pass, respectively. Stated alternatively, the rod retainers
310A-310B are positioned such that the rod members 300-302 are supported thereby
in a generally vertical position and in contact with the gear member 304. Rod
member 300 is coupled to lever 58. The rod member 300 has an aperture 314
wherethrough end 58G of lever 58 slidably passes. The lever 58 of the linkage
assembly is thus coupled to the rod 300 of the marking assembly. The rod member
300 further has spring member 42 secured thereto such that the marking assembly
is spring biased. The spring member is engaged to the rod member 300 such that
the coil of the spring generally resides perimetrically around an end 302A of
rod member 300. A washer member or flange member 40 is secured to the end of the
rod member and one end 42A of the spring 42 engages the washer 40. The other end
42B of the spring engages the rod retainer member 310B. In the steady-state,
resting position, the marker 44 secured to the rod member 302 resides within the
housing of the marking device 10. The rod member 300 is spring biased downward
(with respect to the view given by FIGS. 62 & 63) and the relay action of the
gear member relays the bias to rod member 302 to bias rod member 302 upwards. A
disengaging member 320 is provided to arrest the clockwise bias of lever 503 to
arrest the engagement of a linkage engaging aperture 500 by the lever 58 and
thereby arrest the marking action of the marking device 10 as desired. The
disengaging member comprises a spring biased shaft member 322 secured to an
inside wall of the housing 12. A helical spring member 328 is disposed on the
shaft member 322 such that the spring member 328 generally encompasses the shaft
328. A collar member 324 is slidably disposed on the shaft 322 such that the
collar member 324 is spring biased toward the lever member 503 (see FIG. 64).
The collar member 324 comprises a tapered end 326 terminating in a secondary
collar member 322A. The secondary collar member 322A has a diameter that is
smaller than the collar member 324, and protrudes through an opening 325 in the
housing 12. When the disengaging member is in the "steady-state" resting
position, the larger diameter collar member 324 resides against the lever 503
such that the clockwise bias of lever 503 is interrupted. The interruption of
the clockwise bias of lever 503 causes the pointed end 58f of lever 58 (see FIG.
62) to miss the linkage engaging member(s) 500. The lever 503 is made to operate
by pressing and holding the end 322E of secondary member 322A, such that the
collar member 324 no longer impedes the clockwise bias of lever 503 (see FIG.
63). Continuing to refer to FIGS. 62-66 for operation of the embodiment of the
marking device 10 depicted thereby lever 400 of the positioning assembly is
slidably operated to select a lateral position relative to tape 20 for engaging
a linkage engaging aperture corresponding thereto. As lever 400 is moved, lever
58 is moved accordingly. The end 322E of the disengaging member 322A is then
pressed to allow lever 503 to spring clockwise and cause end 58f to be ready to
engage the next linkage engaging aperture as tape 20 rolls downward past shaft
70. Linkage engaging aperture 500 rolls by and the spring bias of lever 503
causes pointed end 58f of lever 58 to enter the linkage aperture 500. As the
tape is pulled further downward, the pointed end 58f of lever 58 is pulled
downward and opposite end 58G is forced upward. The rod member 300 coupled to
end 58G of lever 58 is likewise forced upward and the plurality of teeth 301 of
rod member 300 engaged to gear member 304 causes the gear member to rotate
counter-clockwise (with respect to the view shown by FIGS. 62 and 63). The teeth
303 of rod member 302 engaged to the gear member 304 accordingly force the rod
member 302 downward, causing the marker 44 to extend through the housing 12 and
deposit mark 48 on substrate 50. Tape 20 is further pulled downward past shaft
70 and as pointed end 58f of the lever 58 leaves the linkage engaging aperture,
the spring member 42 biases the rod member 300 downward pushing the rod member
302 upward, simultaneously pushing end 58G of the lever 58 downward. Pointed end
58f of lever 58 is correspondingly pushed upward, and the resting "steady-state"
of lever 58/lever 503/and rod 300 is re-established. Alternatively, the
disengaging member 320 is not pressed and the linkage engaging members of tape
20 do not engage the pointed end 58f of lever 58 because lever 503 cannot rotate
clockwise as it is blocked by collar member 324.
Referring to FIGS. 68-70 for another embodiment of the invention, the marking
device 10 is shown having a modified marker assembly and linkage assembly. The
disengaging assembly 320 is disposed in the housing such that the collar member
324 and the secondary collar member 326 as discussed above act on a generally
L-shaped shaft 350 instead of lever 503. The generally L-shaped shaft comprises
an end 350A and a pointed end 350P. The end 350A may be engaged to the
disengaging assembly 320 as shown in FIG. 68 to arrest the action of the marking
device 10 or disengaged from the disengaging assembly (i.e. to allow lever 350
to be engaged to tape 20) to enable the marking action of the marking device.
When in the disengaged mode, the end 350A abuts the secondary collar 322A, to
prevent the shaft 350 from extending fully. The modified marker assembly 30 for
this embodiment comprises the marker 44 secured to a bottom end 348B of a shaft
348. Shaft 348 is coupled to the housing 12 by a retaining lug member 449 which
has an aperture 445 disposed therein wherethrough the shaft slidably passes. A
lug member 448 is secured to the shaft 348 above the retaining lug 449 for
retaining a spring member 444. The spring member 444 is a typical helical-type
spring which is disposed around the shaft 348 such that the shaft 348 passes
through a center of the spring 444. The spring member is disposed around the
shaft 348 such that the spring is situated between the retaining lug member 449
and the lug member 448. The spring is compressed when shaft 348 is moved
downward by the action of the linkage assembly (as shown in FIG. 69), and biases
the lug member 448 upward to return the marking assembly to the steady-state
position. The linkage assembly in this embodiment is secured to the shaft 348. A
bottom 380B of a shaft guide housing member 380 is secured to a top end 348T of
shaft 348. A top 380T of the shaft guide is secured to another shaft member
348A. The shaft member 348A is coupled to the housing 12 by another retaining
lug member 449A. Like the retaining lug 449, the retaining lug 449A comprises an
aperture 445A wherethrough the shaft 348A slidably passes. The shaft 348/shaft
guide housing 380/shaft 348A combination is thus suspended in apertures 445-445A
of retaining lugs 449-449A respectively. The spring member 444 provides upward
spring bias to keep the marker 44 inside the housing and provide an action
potential. The linkage assembly further comprises a shaft guide member 384
disposed in the shaft guide housing 380 for slidably guiding the L-shaped lever
350. The shaft guide 384 comprises a pair of retaining lugs 454--454 secured to
a bottom of the shaft guide 384 such that the width of the shaft guide housing
380 (refer to FIG. 68) is generally the distance between the pair of retaining
lugs 454--454. Stated alternatively, the retaining lugs 454--454 are spaced such
that the shaft guide housing 380 is held therebetween. Likewise a pair of
retaining lugs 452--452 is secured to a top of the shaft guide housing for
retaining the shaft guide 384 in the shaft guide housing 380. The shaft guide
384 is disposed in the shaft guide housing 380, as shown in FIG. 70, such that
the shaft guide may move side to side or laterally. The lateral movement of the
shaft guide 384 within the shaft guide housing 380 is controlled by the
positioning assembly. The arms 400A-400B, as shown in FIG. 70 are positioned
such that shaft guide 384 is situated therebetween. Thus, as the selector lever
400 is slidably moved along shaft 404, the shaft guide 384 is correspondingly
moved within the shaft guide housing 380 to select a lateral row of the linkage
engaging apertures, such as linkage engaging aperture 500 or linkage engaging
aperture 500A. The shaft 350 is slidably disposed in the shaft guide 384 such
that it may be extended or retracted therefrom, as shown in FIGS. 68 and 69, for
releasably engaging the linkage engaging apertures disposed in tape 20. As
mentioned, the shaft 350 comprises pointed end 350P for engaging and releasing a
linkage engaging aperture 500, and end 350A for engaging the collar member 324
of the disengaging assembly 320. A helical spring member 357 has one arm 357B
secured to a rear end 380R of the shaft guide member and one arm 357A secured to
the end 350A of the shaft member such that a coil 357C of the spring 357
surrounds the portion of shaft member 350 protruding from the rear 380R of the
shaft guide housing 380. Spring member 357 provides bias to the shaft member 350
such that pointed end 350P is biased against the tape 20. Stated alternatively,
with respect to the view in FIG. 68, the shaft 350 is biased to the right by
spring 357, to predispose the pointed end 350P of the shaft 350 to engaging the
linkage engaging aperture.
Continuing to refer to the FIGS. 68, 69, and 70 for the operation of the
embodiment depicted therein, the modified linkage assembly 54 and the modified
marking assembly 30 is provided with the disengaging assembly 320 and the
positioning assembly 401. The disengaging assembly is disengaged from the end
350A of shaft 350 by pressing on end 322A thereof thereby causing the shaft 350
to be biased forward against tape 20 (by the action of spring 357). The selector
lever 400 of the positioning assembly is slidably operated, as shown in FIG. 70,
to select the position on tape 20 for engaging linkage engaging aperture 500,
linkage engaging aperture 500A or any other suitable linkage engaging aperture
which may be disposed on tape 20. The spring 444 holds the linkage assembly 54
and the marking assembly 30 in a "floating" steady state position with the
marker 44 secured to the shaft 348. The spring 357 holds pointed end 350P of the
shaft 350 against the tape 20. As tape 20 is pulled downward over shaft 70,
linkage engaging aperture 500 disposed therein is pulled over pointed end 350P
of shaft 350. The bias of spring 357 on shaft 350 pushes pointed end 350P into
the linkage engaging aperture 500, until end 350A engages secondary collar 322A.
As tape 20 is further pulled downward, shaft 350, being lodged in the linkage
engaging aperture, (see FIG. 69), pulls shaft 348 downward, causing the marker
44 to extend through the opening 16 of the housing and leave a mark 48 on
substrate 50. As shaft 348 is pulled downward, spring 444 provides increased
resistance against lug 448 of shaft 348 to increasingly bias the shaft upward.
As tape 20 is further pulled downward, linkage engaging aperture is pulled away
from the pointed end 350P and pointed end 350P pops out of the linkage engaging
aperture 500 causing the shaft 348 to move upward by the influence of spring
444.
Referring now to FIGS. 71-73 for still yet another embodiment of the invention,
the marking device 10 has the marking assembly 30 and the linkage assembly 54 of
the embodiment of FIGS. 68-70 with a few modifications. A lever member 420
comprising a first end 420A, a second end 420B and a bent section 420C is
coupled to the shaft 350 and the shaft 348. Shaft 350 has the pointed end 350P,
and an end 350X comprising an opening 351 wherethrough a shaft 340 is slidably
disposed (see FIG. 73). The shaft 340 is secured to an end 420A of lever 420. As
best shown in FIG. 71, shaft 348 has a lug member 346 secured thereto such that
the lug member 346 is positioned generally above the lug member 448 and below
the shaft guide housing member 380. The lug member 346 has an aperture 347 (see
FIG. 73) disposed therein for slidably receiving a shaft member 344. Shaft
member 344 is secured to a center section 420C of lever 420, and a helical
spring member 414 is disposed around shaft 344 such that one arm 414A of spring
414 is engaged to the lever 420 and one arm 414B is engaged to lug 346. Lever
420 is disposed such that it may be rotated about shaft 344. With respect to the
view in FIGS. 71 and 72, lever 420 is biased clockwise, such that the shaft
member 350 is pushed forward by the action of shaft 340 (see FIG. 73) on shaft
member 350, thereby creating an action potential. The embodiment of FIGS. 71-73
further has a pair of opposed retaining lugs 456A-456B secured to an inner wall
of housing 12 such that a lug member 458 may be slidably disposed therebetween.
A third retaining lug member 456C is secured to the left of the opposed
retaining lugs 456A-456B (with respect to the view in FIGS. 71 and 72) and a
spring 457 is disposed between the retaining lug 456C and the lug member 458.
The lug member 458 has a lip member 459 secured to one end for engaging an end
420B of the lever 420. Spring 457 biases the lug member 458 forward such that
the lip member 459 is in constant contact with end 420B of the lever 420. It may
be appreciated that a modification of the disengaging assembly 320 is intended
with lip 459, such as, given by way of example only, by forming a slot S into
the housing 12 wherethrough lip member 459 may protrude and be locked into
place. As previously mentioned, the lever 420 comprises a slight bend in the
center section 420C. The bend of the lever 420C preferably comprises an obtuse
angle of about 170 degrees, but it is to be understood that the angle of the
lever may range from any angle suitable for lever 420, such as from about 90
degrees to about 220 degrees. The embodiment of FIGS. 71-73 depicts an angle of
about 170 degrees. Further, as previously mentioned, the shaft 344 is secured to
lever 420 at center section 420C, or at the point the lever begins the 170
degree bend.
Continuing to refer to FIGS. 71-73 for the operation of the invention, the
marking assembly 30 and the linkage assembly are predisposed in a resting or
steady-state position. Disengaging mechanism 320, as shown in FIG. 73, is
disengaged such that the end 420B of lever 420 is not locked into position (i.e.
such that lip 459 is not engaged to end 420B). As mentioned in the operation of
the embodiment of FIGS. 67-70, the positioning assembly 401 is aligned such that
the pointed end 350P of shaft 350 aligns with an appropriate linkage engaging
aperture 500. Spring 414 biases the lever 420 clockwise (respective to the view
in FIGS. 71 and 72) and causes the shaft 340 secured to the lever 420 to pushed
towards tape 20. (see FIG. 71). As seen in FIG. 73, shaft 340 is slidably
disposed in opening 351 of end 350X of shaft member 350. Shaft member is thus
biased towards tape 20 by relaying the clockwise bias of lever 420 via shaft
340. Spring 457 of the disengaging assembly 320 creates an opposing action
potential on end 420B of lever 420 by providing counter-clockwise bias thereon
via the action of spring 457 on the lug member 458 and lip 459 to lock the
linkage mechanism 54 and prevent the pointed end 350P from engaging the linkage
engaging aperture 500 (as shown in FIG. 71). The disengaging assembly 320 is
disengaged by pulling lip 459 away from end 420B of lever 420. As previously
mentioned, the housing 12 may comprise a slotted opening S (as shown in FIG.
73A) wherethrough lip 459 protrudes such that it may be disengaged from end 420B
of lever 420. After the disengaging assembly 320 is disengaged from lever 420,
as tape 20 is pulled downward past shaft 70, pointed end 350P rests thereon. As
linkage engaging aperture is pulled past the pointed end 350P as tape is further
pulled downward past shaft 70, the pointed end 350P is pushed into the aperture
by the action of spring 414 (see FIG. 73) on lever 420 (see FIG. 71). Thus the
pointed end 350P enters the linkage engaging aperture 500 and becomes engaged
thereto. As the tape is further pulled downward, having pointed end 350P lodged
therein, the shaft 348 is pulled downward as in the embodiment of FIGS. 67-70.
Lever 420 turns clockwise, as shown in FIG. 72. As shaft 348 is pulled downward,
the marker 44 protrudes opening 16 to mark substrate 50. As the tape is still
further pulled downward, pointed end 350P slips out of the linkage engaging
aperture, and spring 444 of the marking assembly drives shaft 348 upward. Shaft
350/shaft 348 are then returned to steady-state or resting position for the next
linkage engaging aperture.
Referring to FIGS. 74-76 for another embodiment of the invention, the marking
device 10 is provided having the marking assembly 30 comprising a state of the
art electrical solenoid member 802 secured to the housing 12. The electrical
solenoid member has a shaft 804 extending therefrom secured to the marker 44. A
retaining lug member 806 having an aperture 806A is secured to the housing such
that the shaft 804 of solenoid 802 passes through the aperture 806A. A battery
member 800 is secured to the housing 12 and an electrical line 820 couples one
electrical side 820B of the battery to one electrical side 820S of the solenoid
802. The positioning assembly 54 of the embodiment of FIGS. 71-73 is provided.
Selector lever 400 having aperture 402 is disposed on shaft 404. The linkage
assembly of this embodiment comprises a state of the art electrical switch
member 810. The electrical switch member 810 comprises a spring member 840 and a
roller member 842 secured to one end of the spring member 840. An electrical
contact 844 is opened when the spring member 840 is pressed toward the body of
the switch 810 (see FIG. 76). Alternatively, the electrical contact established
at sides 824M-822M of switch 810 is closed when the spring member 840 swings
away from the body of the switch 810. Switch 810 is secured to arm 400A of the
positioning assembly 320 such that the switch may be moved by the arms 400A
thereof, as in the embodiments of FIGS. 67-73. An electrical side 822S of the
solenoid is coupled to electrical side 822M of the switch via electrical line
822, and an electrical side 824B of the battery is coupled to an electrical side
824M of the switch via electrical line 824. The roller member 842 is positioned
such that as a linkage engaging aperture 500 passes thereby, the roller member
842 enters the linkage engaging aperture 500 thereby closing the electrical
contact at sides 822M-824M to cause the battery 800 to actuate the solenoid
member 802 and drive the marker 44 secured to the solenoid shaft 808 through
opening 16 and mark substrate 50. Spring member 804 causes the marker 44 to
return to a resting position after the contact at sides 822M-824M of the switch
is interrupted.
Referring to FIGS. 77-80 for yet another embodiment of the present invention,
the marking device 10 is shown having basically the same linkage assembly 54 as
the embodiment of FIG. 52, and the same marking assembly as the embodiment of
FIG. 58. The disengaging assembly 320 additionally is fitted thereto. The
marking assembly comprises the string 904 that runs around post 903 (which is
secured to one of the walls, such as shown in FIG. 61) and is subsequently tied
to the top of the shaft of the marker 44. As lever 53 is rotated (by the action
of the pointed end 58f in linkage engaging aperture 500), the string 904 is
simultaneously pulled causing the marker device to move up and down. The lever
503 biases the lever 53 clockwise (with respect to the view given in FIGS.
77-78) such the lever 58 is pushed towards the tape 20. The disengaging assembly
320 acts upon the lever 503, interrupting the clockwise bias of lever 503 on
lever 58 when collar 324 engages lever 503. When the end 322A is depressed, the
lever 503 rotates clockwise to allow the lever 58 to push against the tape 20
and engage the linkage engaging aperture 500 as it passes by when tape 20 is
pulled downward past shaft 70. A rest stop member 850 is secured to the housing
such that when the lever 58 is in a resting position, the spring bias of the
marking assembly 30 does not pull the lever 58 counterclockwise too much. The
positioning assembly of the embodiments of FIGS. 67-76 has arms 400A-400B
secured to the lever 58. Lever 58 is slidably disposed on shaft 62 of the lever
503, such that the selector lever 400 of the positioning assembly may slide the
lever 58 with arms 400A-400B.
While the present invention has been described herein with reference to
particular embodiments thereof, a latitude of modification, various changes and
substitutions are intended in the foregoing disclosure, and it will be
appreciated that in some instances some features of the invention will be
employed without a corresponding use of other features without departing from
the scope of the invention as set forth.
