PILFER-PROOF MERCHANDISE CARD HOLDING DEVICE
Abstract
A pilfer-proof merchandise card holding device is disclosed
which supports the cards by an opening formed thereon for that
purpose. The device provides for preventing the removal of the
cards until the merchandise is sold. In one embodiment of the
device an elongated tubular hanger for the cards is provided with a
retaining post on the outer end thereof. A spring loaded actuating
rod extending from the rear of the hanger maintains the retaining
post in a vertical position to prevent the removal of the cards.
When the actuating rod is depressed the post is adapted to be
pivoted to a position aligned with the hanger to enable the removal
of the cards. The device is provided with a locking mechanism which
prevents the actuating rod from being depressed until unlocked by a
sales clerk. In another embodiment of the device a plurality of
spaced vertical posts extend upwardly through a slot provided along
the upper wall of the tubular hanger. A card is supported between
each of the posts. The posts rest on a shelf within the hanger and
are attached to a chain. When the actuating rod is depressed, the
chain is adapted to be advanced causing the posts to be moved along
the slot toward the front end of the hanger so that the forwardmost
post is carried by the chain down into the hanger. The card that
was being retained by that post can thus be removed from the
hanger. The actuating rod is arranged to be depressed by the action
of a lever which operates as a result of the insertion of a coin in
a coin machine.

Description
This invention relates to merchandise card holding devices and more
particularly to structures for making such devices pilferproof.
It is well known to display merchandise cards in retail stores by
supporting the cards on hangers. Each card is formed with an
opening by which it is supported on the hanger. Displaying
merchandise in this manner is very desirable since it enables the
customer to view the merchandise and select the ones which he is
interested in purchasing without taking up the time of the sales
clerk. However, when the merchandise is displayed in this fashion,
pilfering of the merchandise cards is quite common. Therefore,
there is a need for a merchandise card holder which provides for
securing the card on the holder until the merchandise is ready to
be sold.
In one embodiment of the card holding device of the present
invention, an elongated tubular hanger for the merchandise card is
provided with a retaining post on the outer end thereof. The
retaining post extends through a slot on the outer end of the
tubular hanger and its lower end is pivotally attached to the end
of an actuating rod which is slidably movable within the hanger. A
rear portion of the actuating rod extending beyond the back of the
hanger is provided with a spring which normally holds the rod
withdrawn from the hanger. When the rod is in its withdrawn
position the retaining post on the outer end thereof is maintained
in its vertical position which prevents the cards from being
removed off the end of the hanger. When the rod is depressed into
the hanger against the action of the spring on the rear portion
thereof, the retaining post is pivoted downwardly to a position
aligned with the surface of the hanger which permits the cards to
be removed from the end of the hanger. A locking mechanism is
associated with the card holding device which prevents the
actuating rod from being depressed into the hanger until unlocked
by the sales clerk.
In another embodiment of the card holding device of the present
invention the tubular hanger is provided with a slot along the
length of its upper wall and an elongated horizontal shelf is
formed within the tubular hanger below the slot. Within the tubular
hanger a clutch and sprocket drive is rotatably supported adjacent
the inner end of the shelf and a cylindrical guide is supported
adjacent the outer end of the shelf. A continuous loop of chain
encircles the shelf with one end of the loop fitted on the sprocket
drive and the other end of the loop positioned about the
cylindrical guide. A plurality of spaced retaining posts are
attached to the sides of the chain with the posts attached to the
portion of the chain below the shelf resting on their sides on the
bottom of the tubular hanger and with the posts attached to the
portion of the chain above the shelf resting with their bottoms on
the shelf such that they extend vertically through the slot on the
upper wall of the hanger. An actuating rod extending from the rear
of the hanger and provided with a spring for holding it in its
withdrawn position is provided with a rack on the inner end thereof
which engages a pinion on the end of the clutch which drivingly
engages the sprocket drive. Thus each time the actuating rod is
depressed against its spring the chain is advanced in its path
about the shelf to permit the forwardmost post resting on the shelf
to be drawn by the chain into the tubular hanger below the shelf,
thus freeing a merchandise card for withdrawal from the end of the
hanger. A coin machine is associated with the card holding device
which operates to depress the actuating rod and thus free a
merchandise card when a coin is inserted in the machine.
Accordingly, one of the objects of the present invention is to
provide a pilfer-proof merchandise card holding device.
Another object of the present invention is to provide a locking
mechanism for a merchandise card holding device which permits a
sales clerk in a store to quickly unlock the holding device to
permit it to be actuated for the purpose of removing a card
therefrom.
Another object of the present invention is to provide a
pilfer-proof merchandise card holding device which permits a single
merchandise card to be released each time the card holding device
is actuated.
It is another object of the invention to provide a merchandise card
holding device which is actuated to permit a card to be removed
therefrom by the use of a coin machine.
It is still a further object of the invention to provide a
merchandise card holding device which is adapted for mounting on a
standard pegboard.
Other objects and features of the present invention will become
apparent from the following detailed description considered in
connection with the accompanying drawings.

A first embodiment of a pilfer-proof merchandise card holding
device in accordance with the present invention, as shown in FIGS.
1 to 6, inclusive, will first be described. The card holding device
10 there shown comprises a hanger support 11 having an opening 14
therein in which the flared end 13 of an elongated tubular hanger
12 is attached by welding, for example. Hanger support 11 is
provided with a pair of spaced lugs 15 on the upper corners of the
back surface thereof which are insertable in spaced holes 16 of a
pegboard 17.
Positioned for sliding movement within tubular hanger 12 is an
elongated actuating rod 20. The rear portion of the rod 20 is
provided with a spring 23, one end of which contacts a head 21 on
the end of the rod 20, and the other end of which contacts the back
surface of the hanger support 11 so as to normally hold the rear
portion of the rod 20 in its withdrawn position relative to the
hanger 12.
The hanger 12 has formed on its upper wall, inward from the forward
end thereof, a short longitudinal slot 24. Transversely aligned
side holes 26 are provided on the sides of the hanger 12 below the
front end of the slot 24. The forward end of the rod 20 is formed
with a slot 28 provided with transverse holes 29. A card retaining
post 30 is provided in the form of a flat vertical stem 31 having
an angularly disposed transverse stop 32 on the top thereof. The
post 30 is positioned with its stem 31 in the slot 28 of the rod. A
hole 33 is provided in the lower portion of the stem 31 of the post
30.
To assemble the post 30 and the rod 20 within the tubular hanger
12, the rod 20 is positioned in the tubular hanger 12 with the slot
28 on the forward end thereof aligned with the longitudinal slot 24
on the hanger 12. The stem 31 of the retaining post 30 is then
inserted into the slot 28 of the rod 20 with its hole 33 aligned
with the holes 29 in the sides of the slot 28. With the post 30 and
rod 20 so aligned, they can then be axially moved forwardly within
the tubular hanger 12 so that the holes 29 line up with the holes
26 provided on the sides of the hanger 12, thus permitting a pin 34
to be inserted into the holes 29 to pivotally attach the stem 31 of
the retaining post 30 within the slot 28 provided on the end of the
rod 20. When so assembled the stem 31 extends through the slot 24
on the upper wall of the tubular hanger 12 and the bottom of the
stem 31 contacts the lower, inside surface of the tubular hanger
12.
When the rear portion of the actuation rod 20 is held in its
withdrawn position by the spring 23, the stem 31 of the retaining
post 30 is effectively secured in its vertical position.
Merchandise cards 18 being supported by their openings 19 on the
hanger 12 are thus prevented from being removed off the end of the
hanger which is provided with a rounded end plug 27. The lower rear
corner 35 of the stem 31 is rounded so that when the actuating rod
20 is pushed into the tubular hanger 12 against the action of
spring 23, the contact of the front side of the stem 31 with the
wall on the end of slot 24 causes the inclined transverse stop 32
on the upper end thereof to be pivoted downwardly. With the stop 32
resting on the surface of the tubular hanger in parallel alignment
with the axis thereof, as shown in FIG. 3, the cards 18 of
merchandise being supported by their openings 19 are able to be
removed from or inserted on the outer end of the hanger 12.
A pusher plate 37 is attached on the back of the pegboard 17 by
upper and lower U-shaped brackets 39 and 40. The pusher plate 37 is
preferably formed from a rectangular sheet of steel with a pair of
ears 41 extending inwardly from the upper corners thereof and a
pair of ears 42 extending inwardly from the lower corners thereof.
The closed end of the upper U-shaped bracket 39 is pivotally
attached by pins 43 to the upper pair of ears 41 on the pusher
plate 37, and the closed end of the lower U-shaped bracket 40 is
pivotally attached by pins 44 to the lower pair of ears 42 on the
pusher plate 37. The free ends of the arms 45 of the upper bracket
39 are attached by pins 46 to flat surfaces 47 machined on the
bodies of upper round head screws 48 that extend through holes 16
located in the pegboard above the hanger support 11. The free ends
of the arms 50 of the lower bracket 40 are attached by pins 52 to
the flat surfaces 51 machined on the bodies of lower round head
screws 53 that extend through holes 16 located in the pegboard 17
below the hanger support 11. The bodies of the lower screws 53 are
each provided with a shoulder 54 on the end thereof. Each of the
upper screws 48 and lower screws 53 is held in position in the
pegboard 17 by a washer 57 and nut 58. The shoulders 54 on the end
of each of the lower screws 53 limit the outward pivoting movement
of the arms 50 of the lower bracket 40 when the spring 23 on the
end of the actuating rod 20 urges the rod to be maintained in its
withdrawn position with the head 21 of the rod abutting up against
the front surface of the pusher plate 37. When in this position the
stem 31 of the retaining post 30 on the end of the rod 20 is in its
vertical position, as shown in FIG. 2, in which position the post
30 prevents the removal of a card 18 from the tubular hanger
12.
It should now be clearly understood that in order to remove a card
18 from the tubular hanger 12 it is necessary to pivot the post 30
to align the transverse stop 32 on the top of the post 30 with the
axis of the tubular hanger 12 so as to enable the card 18 to be
slid past the post 30 and off the end of the hanger 12.
A lock 60 is provided on the pegboard 17 for normally holding the
pusher plate 37 in its outward position, in which position the
cards 18 being held by their opening 19 on the hanger 12 are
prevented from being removed therefrom. The body of the lock 60
extends through an enlarged opening 61 in the pegboard 17 with the
shoulder 62 thereof against the front surface of the peg board. A
nut 63 engages the threaded portion 64 of the body of the lock
extending through the pegboard 17 and contacts the back surface of
the pegboard. The lock 60 is provided with a central rotatable
shaft 64 having a rectangular cross section on the end thereof
which fits in a similarly shaped opening 66 on the inner end of a
lock arm 67 and is secured by a set screw 68. Upon inserting a key
(not shown) in the keyhole 69 of the lock 60, the arm 67 can be
swung to extend in front of and adjacent the front surface of the
pusher plate 37 thus preventing it from being pushed inwardly.
When the key is rotated in the opposite direction the arm 67 is
rotated away from the front surface of the pusher plate 37 thus
permitting it to be moved forwardly by pivoting about the arms of
the brackets 39 and 40 so as to advance the actuating rod 20 into
the tubular hanger 12, as shown in FIG. 3. When so advanced the
stem 31 of the retaining post 30 contacts the front end of the slot
24 causing the post 30 to pivot about its pin 34 connected to the
end of the rod until the transverse stop 32 on the post 30 lies
substantially flush with the upper surface of the hanger 12, thus
permitting one or more of the cards 18 to be removed from the end
of the hanger 12.
It is thus seen that the embodiment of the present invention shown
in FIGS. 1-6 provides for retaining a plurality of merchandise
cards 18 on a tubular hanger 12 by use of a retaining post 30
mounted on the end of the hanger. The card holding device 10 is
normally in its locked condition with the post 30 held in its
vertical position so as to prevent the cards 18 from being removed
off the end of the hanger 12. By unlocking the lock 60 of the card
holding device 10, the sales clerk can then push in the pusher
plate 37 which causes the actuating rod 20 to advance into the
hanger 12 and the post 30 on the forward end thereof to be pivoted
downwardly so as to align the inclined transverse stop 32 with the
hanger 12 thus permitting one or more of the cards 18 to be removed
therefrom.
Upon the sales clerk releasing the pusher plate 37, the actuating
arm 20 is again moved to its withdrawn position by spring 23 and
the retaining post 30 again swings to its vertical position in
which it prevents removal of the cards 18. Then when the shaft 65
of lock 60 is again rotated by a key so as to again position the
locking arm 65 in front of the pusher plate 37, the card holding
device 10 is again placed in its locked condition.
The lugs 15 on the hanger plate 11 have a size and spacing to
accommodate spacing of the holes 16 in the pegboard 17.
Furthermore, the spring 23 on the rear portion of the rod 20 holds
the head 21 of rod 20 against the pusher plate 37 and thus serves
to retain the hanger support 11 on the pegboard 17 after the pusher
plate 37 has once been attached to the back of the pegboard 17.
As shown in FIG. 2 when the retaining post 30 is positioned in slot
24 with the rod 20 held in its withdrawn position by spring 23, the
spring exerts enough force to prevent the post 30 from being
manually depressed and thus pivoted to its aligned position, as
shown in FIG. 3. It is only when sufficient pressure is applied
against pusher plate 37, after the locking arm 67 has swung free,
that the actuating rod 20 is movable within the tubular hanger 12
so as to pivot the post 30 to its aligned position which permits
removal of a merchandise card 18.
A variation of the merchandise card holding device 10 is shown in
FIG. 23. Here a pair of side rods 70a and 70b are provided on
either side of the tubular hanger 12. The ends of the rods 70a and
70b are securely attached to the hanger support 11a and extend
therefrom parallel to the hanger 12. A merchandise card 18a, as
shown in FIG. 24, includes a pair of openings 71a and 71b on the
sides of the main opening 19a thereof. The card 18a is positioned
on the card holding device with its opening 19a fitted over the
tubular hanger 12 and its side openings fitted over the respective
side rods 70a and 70b.
A second embodiment of the pilfer-proof card holding device 75 of
the present invention will next be described. It should be noted
that the cross sectional views of the holding device 75, especially
as shown in FIGS. 9 and 10, for example, are greatly enlarged. As
shown in FIGS. 7 and 8 the card holding device 75 includes an
elongated tubular hanger 76 which extends outwardly from a hanger
support 77 being held on a pegboard 79. The card holding device 75
differs from the embodiment shown in FIGS. 1-6 in that it provides
a plurality of spaced retaining posts 80 along a slot 81 provided
on the upper wall of the tubular hanger 76. Each retaining post 80
provides for retaining a merchandise card 84 on the hanger 76 (FIG.
8). An actuating rod 85 having its forward position extending into
the rear opening of the tubular hanger 76 is provided with a spring
86 on the rear portion thereof. As will be described, each time the
actuating rod 85 is depressed into the hanger 76 against the action
of the spring 86, the posts 80 advance forwardly along the slot 81
of the tubular hanger 76 in such a manner that the forwardmost post
80 drops down into the interior of the tubular hanger 76, thus
permitting one of the cards 84 to be removed from the front end of
the hanger 76.
As shown in FIG. 7, the card holding device 75 is automatically
operated by a conventional coin machine 88. Upon placing a coin in
the opening 89 of handle 90 and pushing the handle into the coin
box 91, a rod 92 on the back of the box 91 is released for outward
movement to rotate a lever 93 about a pivot pin 94 on a fixed
support 95a. As shown in FIG. 12, the lower arm 96 of the lever is
attached by a bolt 97 and nut 98 to a clevis 99 on the end of the
actuating rod 85. Thus when the coin machine 88 is actuated, the
rod 85 is depressed into the hanger 76 against the action of spring
86.
FIG. 8 shows a vertical cross sectional view of the card holding
device 75. Tubular hanger 76 is rigidly held by its inner end on
the cylindrical portion 87 of hanger support 77. A vertical portion
100 of support 77 is provided with lugs 95 on the upper corners
thereof which fit into spaced holes 78 on pegboard 79. The interior
of tubular hanger 76, as shown by the cross section in FIG. 10, for
example, is provided with flat opposing vertical side walls 101a
and 101b. The slot 81 on the tubular hanger 76 extends along the
entire length of the upper wall from just forward of the support 77
to the front end thereof. As viewed in FIG. 10, the slot 81 is
located to the left of the vertical axis of the hanger 76. A short
slot 82 extends along the portion of the bottom wall of hanger 76
in front of hanger support 77 and a short slot 83 extends along the
portion of the bottom wall on the outer end of the hanger 76.
As best shown in FIG. 16, a horizontal shelf 102 is formed within
the tubular hanger 76. The shelf 102 extends from a point spaced
inward from the support 77 to a point spaced inward from the
forward end of hanger 76. Positioned on a pilot shaft 112 rotatably
mounted in a bearing 126 on the side wall of hanger 76 and adjacent
the inner end of the shelf 102, as viewed in FIG. 8, is a sprocket
drive comprised of a drum 103 having an intermediate cylindrical
portion provided with sprockets 106. Mounted within the hanger 76
adjacent the outer or forward end of the shelf 102 is a stationary,
cylindrical guide 105. As shown in FIG. 9, the stationary guide 105
is fixed in position against the flat vertical side wall 101b of
hanger 76 by a screw 133. The guide 105 includes a reduced diameter
cylindrical surface 135. A loop of chain 107 is positioned within
the tubular hanger 76 with the links on one end of the loop fitted
on the sprockets 106 on the cylindrical portion of drum 103 and the
links on the other end of the loop slidably positioned on the
cylindrical surface 135 of the guide 105. It is thus seen that the
chain 107 encircles the shelf 102. As shown in FIG. 9, a flat
projection 106a extends along the top inner wall of the hanger 76
above the shelf 102. The projection 106a provides an upper surface
against which the chain 107 bears. The retaining posts 80 are each
held to be freely rotatable on a pin 111 insertable in an opening
in the side of a link 136 of the chain 107 (FIG. 22). The end of
pin 111 may be secured to link 136 by welding.
As shown in FIG. 8, the posts 80 attached to the portion of the
chain 107 spanning the upper surface of the shelf 102 are
vertically oriented with their flat bottoms resting on the top
surfaces of the shelf 102, and posts 80 attached to the portion of
the chain 107 spanning the lower surface of the shelf 102 are
horizontally oriented with their sides resting on the inner lower
wall of the tubular hanger 76. As described subsequently herein,
when the actuating rod 85 is depressed into the hanger 76 a rack
115 formed on the inner end of the rod 85 engages a pinion 116 on
the end of a clutch 118 which rotates the drum 103 and advances the
chain 107 in a clockwise direction about the shelf 102 until the
forwardmost post 80 on the end of the tubular hanger 76 advances to
the end of the upper surface of the shelf 102 and is lowered down
into the tubular hanger 76 and below the shelf whereat it is
advanced in the opposite direction while in a horizontal position.
This frees one of the cards 84 so that it can be removed from the
forward end of the tubular hanger 76. The spring 86 on the rear
portion of the actuating rod 85 provides for returning the rod to
its withdrawn position after it has been actuated by placing a coin
in the coin machine 88.
A set screw 119 passes through the bottom of the cylindrical
portion 87 of support 77 and the tubular hanger 76. As shown in
FIGS. 8 and 13, the set screw 119 extends up into a slot 120a
extending along the bottom of the rear portion of the actuating rod
85 and limits the inward travel of the rod during which the rack
115 on the forward portion thereof rotates the pinion 116 and
advances the chain 107 so that the posts 80 are advanced the proper
amount to release one of the cards 84.
The hanger support vertical portion 100 and housing 138 may be
formed from a single flat sheet of steel that is stamped to provide
the shapes of the lugs 95, the opening 87a for the cylindrical
portion 87, the sides of the housing 138, and the cut for the
spring support 136a. The upper corners of the vertical portion 100
are then bent back to form the lugs 95 and the lower portions of
the sheet are bent horizontally and upwardly to form the sides of
housing 138 and the support 136a for the end of a reloading leaf
spring 137 enclosed within the housing. The housing 138 also
functions as a support for the tubular hanger 76. The cylindrical
portion 87 of the support 77 is then attached by welding, for
example, to the wall of opening 87a on the vertical portion
100.
As best shown in FIGS. 13 and 21, the actuating rod 85 is provided
with flat vertical sides 109a and 109b which slidably engage the
flat vertical sides 101a and 101b on the interior of the tubular
hanger 76. As shown in FIG. 21, the side of the forward portion of
the actuating rod is cut away so that the remaining wall has a
cross section in the form of a segment. A rectangular end opening
115a is then machined in the remaining wall and the upper surface
of the opening is provided with teeth to form a rack 115. The
forward end of the solid portion of actuating rod 85 is further
provided with a side relief 113 for the posts 80 and a circular
relief 114 into which the clutch 118 and drum 103 can be positioned
when the actuating rod 85 is advanced into the tubular hanger
76.
A cross sectional view showing the clutch 118 and drum 103
rotatably supported in the tubular hanger 76 is shown in FIG. 14.
The drum 103 which may be a molding is provided with recesses 104
on its face and notches 131 on its periphery (FIG. 21). The
intermediate cylindrical portion of the drum 103 is provided with
the sprockets 106 and the end portion of the drum 103 opposite the
face is formed with flat side surfaces 108 and provided with a
central opening 110 for receiving the pilot shaft 112. The central
opening 110 extends thorugh the drum 103. The clutch 118 which may
also be a molding is provided with projections 120 on the face
thereof and formed with a central shaft 132 which projects from
either end thereof. One end of the central shaft 132 resides in the
central opening 110 of the drum 103 and the opposite end of the
central shaft 132 is rotatably mounted in a bearing 128 secured to
the side wall of the hanger 76. Pinion 116 is secured on the end of
central shaft 132 of the clutch 118 and is engaged by the teeth of
the rack 115. Thus when the clutch 118 is rotated in a clockwise
direction by the inward travel of the rack 115 formed on the front
portion of the actuating rod 85, the projections 120 on the face of
the clutch 118 mesh with the mating recesses 104 on the face of the
drum 103 resulting in the chain being advanced an incremental
distance along its path.
A conical spring 121 holds the face of drum 103 in engagement with
the opposing face of the clutch 118. When the actuation rod 85 is
returned by the spring 86, the conical spring 121 permits the faces
of the clutch 118 and drum 103 to be separated as the walls of the
projections 120 of the clutch slip relative to the walls of the
recesses 104 on the drum 103. As viewed in FIGS. 19 and 20, a
sliding member 124 provided with a groove 125 on the side thereof
fits in a longitudinal slot 117 formed on the rear portion of the
shelf 102 and thus straddles the wall of the slot. The sliding
member 124 is provided with a dog 123 on the rear end thereof and
with a stop 122 on the top thereof. The sliding member 124 is urged
in a forward direction by a spring 127, one end of which is fitted
on a pin 129 held on the end of the slot 117 of the shelf 102. The
other end of the spring 127 is positioned in an opening 130 in the
end of the sliding member 124 opposite dog 123. Normally the dog
123 is urged to engage one of the notches 131 on the periphery of
the drum 103 to thereby prevent the chain 107 and thus the posts 80
from being moved in a clockwise direction. Likewise the teeth of
the rack 115 normally engaged the pinion 116 on the clutch 118 to
thereby prevent the chain 107 from being moved in the
counterclockwise direction. The cards 84 are thus secured on the
hanger 76 by the posts 80.
As shown in FIGS. 16 and 17, in order to facilitate the movement of
the posts 80 on the chain 107 about the stationary guide 105, a
take up element 139 is positioned within the front end of the
tubular hanger 76. The front end portion 140 of take up element 139
has a sliding engagement within the tubular hanger 76 and the
opposite end portion of the take up element 139 forms a caming
finger 141 which provides a ramp for the posts 80. The slot 83 is
provided below the tubular hanger 76 to enable the caming finger
141 to be slipped on the end of the hanger 76. The take up element
139 is urged in a forward direction by a spring 142 which has one
end seated in an opening 143 on the front end of the take up
element 139 and its other end seated in an opening 144 on the rear
end of cap 145 which is securely attached on the end of the tubular
hanger 76.
In order to load the card holding device 75 with cards 84, it is
necessary to reverse the direction of travel of the chain such that
it rotates in a counterclockwise direction, as viewed in FIG. 8,
after a card 84 has been placed on the front end of the tubular
hanger 76. To accomplish this, which can be done by the shop keeper
after hours, the actuating rod 85 is released from the lever arm 96
by removing the bolt 97. The set screw 119, which is used for
retaining the actuating rod 85 in the tubular hanger 76 and for
limiting its travel, is then removed. The actuating rod 85 is then
withdrawn from the tubular hanger 76. Referring to FIG. 18, a tool
(not shown) is then used for moving the sliding member 124 forward
against its spring 127 by contacting the stop 122 on the top
thereof, thus causing the dog 123 to be disengaged from a notch 131
of the drum 103. The chain 107 which is now free to be moved in
either direction is moved in the counterclockwise direction, as
viewed in FIG. 8, to enable the posts 80 to be loaded one at a time
with cards 84. As each post 80 approaches the rotating drum 103,
its movement is synchronized so that the bottom of the post rests
on one of the flat side surfaces 108 on the end portion of the drum
103. As the posts continue to rotate counterclockwise about the
drum 103, the leaf spring 137 enclosed in the housing 138 below the
tubular hanger 76 provides for lifting and guiding the posts 80
into their horizontal positions on the bottom of the hanger 76
after they once leave the flat side surfaces 108 of the drum 103.
Similarly, as shown in FIG. 17, as the posts 80 are advanced by the
chain 107 about the stationary guide 105 the caming finger 141 of
the take up element 139 functions to guide the posts 80 of their
vertical position on the top of the shelf 102.
While in order to comply with the statute the invention has been
described in language more or less specific as to structural
features, it is to be understood that the invention is not limited
to the specific features shown but that the means and construction
herein disclosed comprise a preferred form of putting the invention
into effect and the invention is therefore claimed in any of its
forms or modifications within the legitimate and valid scope of the
appended claims.
