Summary of the Invention
The method of the invention utilizes an anvil
and a cooperable plunger which are movable relative to
each other. The anvil and the plunger are cooperable to
hold a tag and merchandise in a bent orientation so that
a pin can be driven through both the tag and the merchandise.
A movable member which is movable relative to the plunger and
the anvil, is repeatedly moved during the time a pin is
driven through the tag and the merchandise to assist in
guiding and bending the pin firstly through the tag, secondly
through the merchandise, thirdly again through the merchandise,
fourthly again through the tag and fifthly again through the tag.
The movable member is also effective to crimp the pin which
has been completely inserted or almost completely inserted
through the tag and merchandise. The crimping operation bends
the leading marginal end of the pin so that the point of the
pin is inclined toward the underside of the tag and away
from the merchandise. Thus, crimping is that action which
relates to a final bending of the pin primarily to make it
difficult to remove and reinsert through the tag and merchandise.
According to a specific embodiment of the method, merchandise
is positioned at a pinning zone between the anvil and the
plunger, a tag is fed along a path to the pinning zone while
a movable pin guiding and crimping member is spaced from the
path. The pin guiding and crimping method is now moved
for the first time toward the plunger. Thereafter, the plunger
is moved toward the anvil to hold the tag and the merchandise in
a bent orientation at the pinning zone. Thereupon, a pin is
~ - 2 - ~

driven through both the tag and the merchandise once and
thereafter the pin driving and crimping member is moved a
second time away from the plunger to allow the pin to be
driven through both the tag and the merchandi~e again. The
S pin guiding and crimping member moves a third time toward the
plunger while the pin is being driven to bend the pin toward
the tag to enable the pin to be driven through the tag again.
When this has been accomplished, the pin guiding and crimping
member is moved the fourth time away from the plunger. There-
after, the pin guiding and crimping member is moved a fifth
time toward the plunger but to a greater extent than during
the first and third times while supporting a leading end
portion of the pin to crimp the pin. There is also provided
apparatus for carrying out the method. ~n improved apparatus
relates primarily to the mechanism for controlling the oper-
ation of the movable member which serves the dual function
of guiding the pin and crimping the pin. According to a
specific embodiment of the invention, a cam shaft drives
an actuator which is coupled to the movable pin guiding
and crimping member, to the pin driver and to the paper strip
feeding mechanism. The actuator drives the movable member
through an arrangement of cams which cause the movable member
to undergo repeated movements as characterized above with
respect to the method. Accordingly, a pin which is originally
straight, is driven through both the tag and the merchandise
and the bending of the pin and the subsequent crimping of the
pin is under the control of the movable member.

also has a shaft portion 62 which is suitably secured to the :
input side 63 of a single revolution wrapped-spring clutch
64. The clutch 64 is engaged by the action of an electromagnet
or solenoid 65. Output side 66 of the clutch 64 is secured
to cam shaft 67. The cam shaft 67 is thus rotatably supported
: by the bearing 61 and in a bearing 70 mounted in a bracket 71 :
(FIGURES 23 and 29). Cams 72 through 76 and a crank 77 are
secured to and rotate as a unit with the cam shaft 67.
The speed reducer 52, the bearing 61, and the
bracket 71 are secured to a generally horizontal.base plate 78
(FIGURE 29) of a frame generally indicated at 79. The frame
79 also includes a generally horizontal frame plate 80
(FIGURE 29) disposed above the base plate 78. The base plate
78 mounts a bearing 81 and the frame plate 80 mounts a bearing
~ 82 disposed vertically above the bearing 81, Referring again
to FIGURE 1, there is shown a generally vertical shaft
83, which is rotatable in the bearings 81 and 82. An arm
84 is secured to the shaft 83 by a set screw 85. An actuator
86 is spaced from the arm 84 by a washer 87. The shaft 83
extends through a hole 88 in the actuator 86 and through a

. The shaft 83 carries a bracket 97. The bracket97 i.ncludes aligned posts 98 and 99 (FIGURE 29) for rotatably
mounting respective roller followers 100 and 101. The followers
. 100 and 101 are driven by respective cams 72 and 73 to rock
the shaft 83 in opposite directions about the generally
vertical axis A as indicated by double-headed arrow 102 in
:. FIGURE 1. One complete revolution of the cam shaft 67 will cause
: the actuator 86 to be driven in the clockwise direction as
viewed in FIGURE 1 to move a pin driver 103 generally to
the left and will thereafter cause the actuator 86 to be
driven in the counterclockwise direction to move the pin
driver 103 generally to the right.
A bracket 104 is secured to the base plate 78 by
fasteners 105 (FI~URE 29). The bracket 104 has aligned holes
106 which rotatably mount end portions 107 of a shaft 108.

together as a unit. The lever 114 has a bifurcated end 121
which receives a pin 122 which extends through bifurcated end
123 of a plunger 124. The plunger 124 is suitably guided
for generally vertical movement along a vertical axis Al
- 5 in a guide 125 (FIGURE 21). The guide 125 is secured to a
frame member or plate 126 which also consititutes part of the
frame 79. The upper end of the plunger 124 has a pin guide
groove 127. The plunger 124 is cooperable with an anvil
generally indicated at 128. The anvil 182 is shown dia-
grammatically in FIGURE 1 and in detail in FIGURE 18.
Movably mounted to the anvil is a movable member 129 (FIGURE 18)
which serves the dual function of guiding and crimping the pin.
As seen in FIGURE 1, the crank 77 includes a pin
130. Rotation of the cam shaft 67 causes the pin 130 to be
driven in a circ~lar path. The pin 130 drives a follower
generally indicated at 131. The follower 131 inclu*es a
pair of follower members or sections 132 and 133. A bracket
134 is suitably secured to the base plate 78. The bracket
134 mounts a shaft 135. The follower sections 132 and 133
~`20 are generally flat plates. The follower section 132 is

a face 141 (FIGURE 36) of follower section 132 against the
post 138. As shown in FIGURES 35 and 36 springs 139
and :L40 are connected at their respective ends to posts
142 and 143 on the respective follower sections 132
and 133. In the position of the follower 131 shown in
FIGURES 1 and 35, the follower sections 32 and 133 provide
an elongated slot 144 in which the pin 130, which includes
a roller 145, is received. In that the pin 130 is eccentric
with respect to the cam shaft 67 and because slot 144 is
positioned between the shaft 135 and a pivot 146 secured to
the follower section 133, the pivot 146 travels through a
considerable distance. This movement through a considerable
distance is accomplished using the follower 131 which is
relatively inexpensive to manufacture. With reference to
; 15 ' FIGURE 1, a rod 147 has a hole 148 in which the pivot 146
is received. The other end of the rod 147 passes freely
through a hole in a connector 149. Nuts 150 (FIGURE 2)
threadably received by the rod 147 securely connect the
connector 149 to the rod 147 at a selected position. With
reference to FIGURE 2, the connector 149 has a hole 151 in
which a post or pivot 152 is received. The pivot 152 is
secured to a block or slide 153. The slide 153 has bearings
154 (FIGURE 23). A rod or guide 155, which is shown to be
annular, extends through and slidably mounts the bearings 154.
The rod 155 is secured at one end to the frame plate 126
~ and at its other end to a frame plate 156 which constitutes

part of the frame 79. The rod 155 extends generally hori-
zontally and is disposed below the frame plate 80 which is
connected to the frame plates 126 and 156. The slide 153
has four upstanding posts 157, 158, 159 and 160 (FIGURE 2)
and respective aligned holes 161 and 162 for receiving res-
pective pivot pins 163 and 164 carried by respective
feed fingers 165 and 166. The posts 157 and 159 have
respective threaded bores 167 and 168 which receive
respective set screws 169 and 170 which can be locked into
position by means of nuts 171 and 172. The set screws 169
and 170 bear against inclined shoulders 173 and 174 of the
respective feed fingers 165 and 166. The set screws 169
and 170 enable individual annular adjustment of the res-
pective feed fingers 165 and 166 with respect to the horizontal.
The feed fingers 165 and 166 are free to move in respective
. slots 175 and-176 in the frame plate 80. The feed fingers 165
and 166 have respective drive faces 177 and 178 which are dis-
posed below respective overhanging abutments or faces 179 and 180.
It is apparent that the initial and final positions of travel

assembly or device generally indicated 182 constitute
a tag feeding mechanism 183 of the apparatus 50. The
tag feeding device 182 is used to separate the bottom tag
T in a stack S held in a hopper generally indicated at
184. The tag feeding device 182 separates the bottom tag T
from the stack S by feeding the bottom tag a predetermined
distance toward a tag attaching or specifically a pinning zone
Z (FIGURE 1) between the plunger 124 and the anvil 128,
and the feed fingers 165 and 166 engage a separated tag T
and feed the separated tag T to the proper position in the
pinning zone Z. The tag feeding device ?82 will be described
.
; in greater detail in connection with FIGURES 24 and 38 through
: 44.
The hopper 184 is constructed to accept tags of
: 15 various lengths and widths. The hopper 184 includes a
; generally vertical side plate 18$ which is secured to the
generally horizontal frame plate 80. A generally vertical
front plate 186 is secured to the frame plate 80 and to the side
., plate 185. The plates 185 and 186 provide reference planes
, .
,.. ;20 for side edges Sl and leading edges Ll of the tags T, res-
~" pectively. A plate or guide 187 is positioned against trailing
~; edges Tl of the tags T, as best shown in FIGURE 26. The guide

The support 191 has a hole 193. A handle 194 is coupled to
a connector generally indicated at 195 secured to the tag
feeding device 182. With reference to FIGURES 2 and 24, the
connector 195 is shown to have a body 196, an annular
flange 197, a shoulder 198, and a screw 199 projecting
from the shoulder. The connector 195 is shown to be of
one-piece construction. The handle 194 and the connector 195
are coupled by a jaw clutch generally indicated at 200.
The jaw clutch 200 i comprised in part by three e~ually
annularly spaced teeth 201 and in remainder by three equally
annularly spaced teeth 202 on the connector 195. The jaw clutch
200 enables the handle 194 to be rotated in opposite directions
to tighten or loosen screw 199. Rotation of the handle 194
so as to tighten screw 199 and cause the support 191 to pivot
counterclockwise (FIGURE 24) due to the action of the flange
197 bearing on the support 191. When the handle 194 is
rotated so as to loosen the screw 199 the support 191 will
pivot clockwise (FIGURE 24) due to gravity. In the position
shown in FIGURE 24, the trailing marginal ends of the tags
T are raised above the plate 80 on which the tags T are
supported. The trailing marginal ends of the tags T rest
.-:
on ledges 203 of the respective support fingers 192 and are
~ thus spaced from the plate 80 that supports the remainder of
- 25 the tags T. In order to prevent the user from breaking the handle 194 by pushing or pulling on it, there are gaps
between the teeth 201 of the handle and the teeth 202 of the

connector 195. A tension spring 204' is connected at one end
to a post 20S' mounted inside the handle 194 and to a post
206' mounted inside the connector 195. Construction of the jaw
: clutch 200 will enable the handle to be deflected with
respect to the connector 195 and the spring 204 will return
the handle 104 to the upright position shown in FIGURES 2
- and 24. The screw 199 is received in a threaded bore 204
~ in frame or body 205 of the device 182. Upon tightening of
:~ the screw 199, the flange 197 bears against the support 191
and the body 205 is drawn up against the underside of the
.,
plate 80 to prevent movement of the support 191, the
associated bracket 188, the plate 187, and the tag feeding
device 182. The screw 199 and a pin 206 secured to the body
: 205 extend through elongated slot 207 in the plate 80.
,:,:
. 15 The pin 206 and upper shank of the screw 199 fit in the
slot 207 with a minimum of clearance so that the tag feeding
:. device 182, the bracket 188, the support 191, and the
guide 187 can be slid for guided movement toward and away
. from the pinning zone Z upon loosening the screw 199. There-
after, upon tightening the screw 199 by rotating the handle
194, the device 182, the bracket 188, the support 191, and
: the plate 187 can be clamped in position. The hopper 184
also includes a side guide generally indicated at 208.
With reference to FIG~RES 2 and 34, side guide 208 is shown to
be movable into guided contact with side edges S2 of the

FIGURES 1 and 2 show the pin driver 103 carried by --
a slide 258. The slide 258 has a socket 260 for receiving a
ball-shaped end portion 261 of an extension 262 threadably
secured to a flange 263 of the arm 86 and held in adjusted

. . and front and rear plates 268 and 269. The plates 266, 267,
268 and 269 are considered to be part of the frame 79.
When the arm 86 pivots clockwise as viewed in FIGURE 1, the
pin driver 103 is driven to the left and when the arm 86
; pivots counterclockwise, the pin driver 103 is driven to
the right. With reference to FIGURE 5, the rear plate
269 mounts a lever 270 for pivotal movement about an adjust-
. 20 able eccentric pivot 271. The one end of the lever 270
.. ` on one side of the pivot 271 is bifurcated as indicated

spring 285 is connected at one end to the post 279 and
at its other end to a post 279' connected to the plate
269. The tension spring 285 normally urges the plate 276
clockwise as viewed in FIGURE S to a position in which the
post 278 rests against the cam plate 284. The cam plate
284 has cam lobes 284a and 284b. The cam lobe 284a is
considered to be an extension of a cam face or surface
286 on the lever 270. The cam face 286 is adapted to be
contacted by a roller 262' on the actuator 86 to pivot the
- 10 lever 270 counterclockwise as the roller 262 moves to the
,.,
left as viewed in FIGURE 10. Counterclockwise pivoting of
the lever 270 will drive the movable member 129 toward the
plunger 124 and the tag T. The member 129 will thus be
driven from the position shown in FIGURE 10 to the position
shown in FIGURE 11. In the position shown in FIGURE 11,
the lever 270 has pivoted counterclockwise and bears against
the lobe 284a. In the position shown in FIGURE 11, the
member 129 preferably just touches a tag T at the pinning
zone Z without bending that tag T. As the cam shaft 67
continues to rotate, the plunger 124 continues to move
upwardly to the position shown in FIGURE 12. It should be
noticed that because of dwell in cams 72 and 73, the roll
;."
262' is in the same position in FIGURES 11 and 12 and the
same is true for the pin driver in 103. However, in
FIGURE 12 the plunger 124 has moved upwardly to its fullest
extent and has bent the tag T which is supported by a guide
185', by edge 314' of an anvil member 311 (FIGURE 18),

member 129 and by a guide or support 185". As the roller
262' continues to move toward the left to the position shown
in FIGURE 13 it encounters a drive face~287 on the plate
276, thereby causing the plate 276 to be rotated clockwise
against the light force exerted by the spring 285.
In the position of FIGURE 13, pin P has passed through
. the tag T and the merchandise M once and is in guided
relationship by a guide groove 129' in member 129. The
.- pin P is inclined downwardly slightly with respect to the
horizontal as shown but remains straight. When the cam-
shaft 67 has rotated so that the roll 262' is in the position
sho~n in FIGURE 14, the lever 270 has rotated clockwise
under the urging of the spring 285, thus raising the member
:: 129 or~ stated another way, moving the member away from the
.15 tag T, the pin P, and the plunger 124. The pin driver 103
:. has driven the pin P to a position in which its leading end
.~ is contacting groove 129". While the roll 262' moves from
the position shown in FIGURE 14 to the position shown in
FIGURE 15, the lever 270 rotates counterclockwise thus
. 20 driving the member 129 toward the plunger 124, the tag T
and the pin P. This movement of the member 129 causes
the pin P to be guided or bent toward the tag T as best
shown in FIGURE 15. As the roll 262' continues to move to
the left the roll 262' moves off the lobe 284b and the lever
: 25 270 is thus urged clockwise by the spring 285, thus raising
. the member 129 away from the pin P, the tag T and the plunger
124. In the position shown in FIGURE 16, the pin P has

. 5 the pin P, the leading marginal end P' of the pin P is
;: driven upwardly as the pin P continues to be pushed to the
left by the pin driver 103. After the roll 262' has moved
to the left to the end of its travel, it begins to move to the
right. When the roll 262' encounters the cam lobe 284b
. 10 the lever 270 pivots counterclockwise to drive the member
129 downwardly, however, when the roll 262' encounters a
cam face 288 on the plate 276 the member 129 is driven
further toward the plunger 124, the tag T and the pin P
into the position illustrated in FIGURE 17 in which the
. 15 pin P is crimped. During crimping the plunger 124 is
momentarily urged downwardly against the action of the spring
. 115. The member 129 is in its maximum downward position
when the lower tip 289 of the cam face 288 is immediately
above the high point of the roll 262'. In the position
.. 20 shown in FIGURE 17, the member 129 has been driven
; downwardly to a greater extent than in the embodiments
:; .
-. of FIGURES 11, 12, 13 and 15. After the drive member 129 has

~:;
270 clockwise and the roll 262' rides along the lobe 284a
and cam face 286 until the drive member 262 has returned to

pins P are carried in the paper strip PS. The paper strip
PS is folded as shown in FIGURE 10 and passes in the folded
` condition under the bottom guide 267 and from there it passes
between the nip of respective idler roll 290 and feed wheel
290'. The feed wheel 290' contains a one-way clutch 291.
The clutch 291 is operated by an arm 292 having a pin 293.
Links 294 and 295 are pivotally connected by a pin 296.
The link 294 is pivotally connected to the pin 293 and the
link 295 is pivotally mounted on a pin 297 mounted to the
plate 269. The drive pin 258' con~acts the link 295
as the slide 258 moves to the left (FIGURE 5) thereby
causing the arm 292 to pivot clockwise and rotating the
feed wheel 290' clockwise as shown in FIGURE 8. A tension

With reference to FIGURE 18, the anvil 128 is
shown to include anvil members 307, 308 and 309. The members
307, 308 and 309 can be considered to be anvil members in that
they individually absorb some of the force exerted by the
s plunger 124. The anvil member 308 is generally plate-
like but has guide members 310 and 311 which provide a
guide groove 312 in which plate-like movable member 129
-~ is received. The anvil member 309 is also plate-like and
serves as a retainer for retaining and guiding the movable
member 129 for straight line movement and more particularly
vertical movement in the groove 312. The anvil member 307
is formed integrally with the plate 269. The anvil member
307, 308 and 309 have respective concave surfaces 313, 314,
and 315 which are shown to face downwardly. The curvature
of the concave s~rface 315 is offset from the curvature of
surfaces 313 or 314 as best shown in FIGURES 10 through 17.
The anvil members 307, 308 and 309 are shown to be held in
assembled relationship by screws 316 and 317 which extend
through respective holes 318, 319, and 321 and 322 and are
threadably received in respective threaded holes 320 and

screws 396c, 397c and 398c and related stop screws 408,
409 and 410, the abutment portions 405, 406 and 407 may contact
stop screws 408, 409 and 410 before the slide 367 has moved
to the end of its travel to the left to its ful}y retracted
position. In this event, the needle mounting members 396',
397', and 398' will actually pivot clockwise. On the
other hand, if the latches 396, 39i and 398 are tripped
before abutment portions 405, 406 and 407 contact stop
screws 408, 409 and 410, then tripping of the latches 396,
397 and 398 will cause the needle mounting members 396',
~Z0 397' and 398' to pivot counterclockwise until their respective
abutment portions 405, 406 and 407 contact respective stop
screws 408, 409 and 410. In any event, needles 411, 412
and 413 mounted by respective members 396', 397' and 398'
remain below the bottom tag T in the stack S. As the slide
382 is lowered, the follower 371 pivots clockwise and the springs
369 and 370 drive the slide 367 to the right. As the slide
367 moves to the right, the needle mounting members 396', 397'
and 398' pivot counter clockwise until pins 396b, 397b and 398b

contact respective abutment faces 396d, 397d, and 398d
during pivotal movement of the needle mounting members
396', 397' and 398' from the position shown in FIGURE 43
to the position shown in FIGURE 44. The abutment faces
396cl, 397d and 398d latch the respective needle mounting
member 396', 397' and 398' in respective positions so that
penetration of the needles 411, 412, and 413 is limited~
; The needles 411, 412, and 413, thus, pivot into impaling
engagement with the bottom tag T. The needles 411, 412
and 413 penetrate or pierce the bottom tag without passing
through the bottom tag T. As the slide 367 continues to move
to the right, the bottom tag T passes through the gate
mechanism 227 to the phantom line position shown in FIGURE 44.
; At the end of travel of the slide 367, namely its fully
extended position shown in FIGURE 44, stop screws or
abutments 414, 415, and 416 abut the needle mounting members
396', 397' and 398' to cause their pivotal movement in a
clockwise direction about shaft 395' so that the latches
396, 397 and 398 can be pivoted clockwise by respective
springs 396e, 397e, and 398e as shown in FIGURE 40.
FIGURE 40 shows the components in the home position as in
FIGURES 38, 39 and 41. It is noted in FIGURE 40 that the
rod 155 passes through a hole 418 in the plate 358 with
adequate clearance so that no part of the tag feeding assembly
182 contacts a rod 155.
With reference to FIGURE 45, the needle mounting
member 396' is shown as having an elongated through-slot
419. The needle 411 is received in the slot 419 and a

flexible resilient plate 420 contacts the needle 411 and
frictionally and removably holds the needle 411 in the slot
419. The plate 420 has a ~ab 421 against which blunt end
422 of the needle 411 is seated. Two screws 423 passing through
respective holes 424 in the plate 420 are received in
threaded holes 425 in the member 396'. An end portion 426
of the plate 420 adjacent the slot 419 is bent outwardly.
A worn needle 411 can be readily removed as by grasping the
exposed end portion with pliers and pulling the needle 411
out of the groove 419. A new needle having a sharp end
can be inserted into the groove 419 using pliers which can
be used to push the needle into the groove until end 422
~ ,.
is seated against the tab 421. The other mounting members
397' and 398' and associated latch components are identical
to those shown in FIGURE 45.
Referring now to FIGURE 46, the switches 344 and 345
include mechanically connected switches 430 and 431 and 432
;~ and 433, respectively. When the switch 344 is closed, the
switches 430 and 431 are closed, and vice versa. When the
switch 345 is closed, the switches 432 and 433 are closed,
and vice versa. The clutch solenoid 65 is connected to a
normally closed switch 434. The switch 430 is connected to
a lead 435 and the switch 434 is connected to a lead 436.
The switches 430 and 432, the clutch solenoid 65, and the
switch 434 are connected in series. The seitches 431 and 433
are connected to the lead 435 and to a node 437'. A coil 438'
of a relay 438 is connected to the node 437' and to a node
` 439. A normally open switch 440 and a normally open switch

441 in parallel with each other are connected to a node
439 and to the lead 436. The switch 440 is controlled
by Zl cam 437 secured to the cam shaft 67. When the cam
; sha~t 67 is in the home position the cam 437 holds the switch
440 open. The electric motor 51 is connected to the leads
435 and 436 through a switch 438a. The motor 51 operates
whenever the switch 438a is closed. When one of the switches
344 or 345 is closed and the other one is open, neither the
clutch coil nor the relay coil 438' can be energized. It
is apparent that manual actuation of the actuator 342
or the actuator 343 without actuation of the other is
ineffective. It is only when the switches 344 and 345 are
~' simtlltaneously in the closed position, that the clutch coil
65 is energized through the switches 430 and 432 and the
normally closed switch 343. Energization of the clutch
,. . .
coil 65 will cause the clutch 64 to be engaged, thereby
causing the cam shaft 67 to rotate. Rotation of the cam
shaft 67 will cause the cam 437 to rotate, thereby closing
the switch 440. When the switch 440 is closed and assuming
,: .
that at least one of the switch elements 431 and 433 is still
in the closed condition, the relay 438 will be energized,
thereby opening the switch 434 and closing the switch 441.
The switches 434 and 441 are part of the relay 438 and are
mechanically coupled to the relay coil 438' as indicated
by respective broken lines 442 and 443. Opening of the switch
434 causes the clutch solenoid to be deenergized thereby
` causing disengagement of the clutch at the end of one complete
;;: ..
~ rotation of the cam shaft 67. Energization of the relay

coil 438' so long as at least one of the switches 431 or 433
is closed, prevents the switch 434 from closing and consequently
prevents energization of the clutch solenoid 65. If both
of t:he actuators 342 and 343 are released, then both the
switches 344 and 345 will be open and consequently the
switches 431 and 433 fail to complete a circuit through
the relay coil 438', thereby causing the switch 434 to close
and the switch 441 to open. Accordingly, the clutch can
only be operated again by actuating both actuators 342 and
343 so that the switches 344 and 345 are simultaneously
in the closed condition. It is apparent that the switch
344 can be closed before the switch 345 is closed, or vice
versa, but it is only when both the switches 344 and
345 are in the closed condition that the clutch solenoid 65
;15 is operated and the clutch solenoid 65 cannot again be
; operated until after both the switches 344 and 345 are
released.
With reference to an al~ernative embodiment
shown in FIGURE 47, there are shown leads 444 and 445. The
lead 445 is connected to a node 446 through a switch 447.
The electric motor 51 is connected to the node 446 and to a
node 448 which is connected to the lead 444. Switches 449 and
450 and the clutch solenoid 65 are connected in series
:~ with each other and in turn to respective nodes 446 and
:"f
448. The switches 449 and 450 are positioned to be acutated
by actuators 342 and 343 and are disposed in the same
positions relative to the actuators 342 and 343 as are the
switches 344 and 345 in the other embodiment. The switches
`~ 449, 450 and 447' are required to be in the closed condition

before the clutch solenoid 65 can be operated. During
operation of the machine, the switch 447 is closed to operate
the motor 51 and consequently actuation of the actuators 342
and 343 such that the switches 449 and 450 are both in
the closed condition at the same time will cause energization
of the clutch coil 65'.
With reference to FIGURE 48, there is shown a
timing diagram showing the movement of the pin driver 103,
the plunger 124, the feed fingers 165 and 166 and the feed
.
~ 10 assembly slide 367, with respect to degrees of cam shaft
; rotation. It is apparent that the device 182 which separates
. . .
the tag T from the stack S moves through an operational
sequence which overlaps the operational sequence of the
tag feeding device 181 which advances the tag T to the
~15 pinning zone. It is to be noted that the movement of the
feed is completed relatively early in the machine cycle to
position a tag T at the pinning zone Z which was separated
from the stock S by the device 181 in the previous machine
cycle. It is apparent that in each machine cycle, a tag
T is positioned at the pinning zone Z and later in the same
cycle a tag T is separated from the stack S.
