'
The main objects of my invention are:
First, to provide a changeable exhibitor or display device for successively presenting cards ofa
vmade comparatively large to permit the exhibi
tion' of yrelatively large cards or display panels
which are indicated by the _reference numeral 3.

displayed.

cards 3 which normally rest on an inclined seat 5
0l whereby the same are urged rearwardly, or
.
whereby they tend to slide rearwardly.
Second, to provide a device of the type described
which is efficient and unfailing in action.
lo
Third, to provide a device of the type described
which is exceedingly simple in its parts and economical of production.
The cards are supported at the rear of the
stack by a pair of spaced inclined depending iin
gers 5 which are adjustable forwardly and rear- 1o
Wardly to accommodate more or fewer cards in a

Fourth, to provide a device of the> type described which is adjustable in character and cal5 pable of accommodating display cards lor panels,
etc., of varying size and nature. _
Fifth, to provide a device of the Itype described
which is capable of presenting a card or panel of
considerable area in comparison to or relative
manner to be hereinafter described.
I provide a pair of depending blade springs 9
fastened at their upper ends Iii to the housing on
either side of opening 2, these springs being com- `1,5
paratively weak and exerting ‘a slight -force on the
fronty card 3 tending to urge the pack of cards
rearwardly against rear support fingers 5. How
ever, the strength of springs 9 is such that the

the description to follow. The invention is deEach of the cards is provided with a hole II ad- .
fined in the claims.
A preferred embodiment of my invention is illustrated in the accompanying drawing, wherein:
Fig. l is a view in perspective of a structure
embodying my invention.

The front side of the hole is coveredby a suitable
tab III adhesively secured to the card, or the
hole may be covered by other means.
At a suitable point interiorly of housing I,
1 provide a platform I2 having adjustably mount- y30v

bracket I8 which is mounted on plate I2I. rThe
`bracket extends upwardly from the plate and is 45
Referring to the drawing, the reference numeral I in general indicates the casing or housing enclosing the operative structure of my invention and provided with a display opening 2
50 in the front wall thereof. The housing I may
be formed of any suitable material; however, I
preferably employa sheet metal structure and cut
the opening at the bottom thereof. It may be
noted that due to the features of construction
55 to be hereinafter described opening 2 may be
pivotally and adjustably connected to the lower
part ISI of an upwardly extending longitudinally
adjustable pulley support by wing nut. |82 on the
pivot |83. The upper part I8!! of the pulley sup.
port is slotted at IBB to receive screws |85 and50
wing nuts I8'I whereby the length of the pulley
support may be adjusted when the position of ‘
shaft I5 is changed. Support part l|84 is pro
vided at its upper end with a suitable spindle I9
whereon a second pulley is mounted.
The pul- 55
2
2,112,692
leys carried on shaft I5 and spindle I9 are num
bered respectively 20 and 2|. The belt 22 is sup
ported and driven by these pulleys.
A belt of
small section, so as> not to impose a serious load
on motor I3, is preferable.
I contemplate that
a chain may also be employed in place of a. belt
transmission.
`
From the foregoing, it will appear that when
it is desired'to shift fingers 5 forwardly or rear
wardly to accommodate more or fewer cards 3,
the motor I3, belt 22 and parts associated there-with are simultaneously and similarly shifted
without changing the operative relation of they
parts in any way.
15
This is accomplished by
simply loosening and shifting plate 'I2I'.
A release or trip 23, the function lof which will
be hereinafter more particularly pointed out, is
secured to bracket I8 by-one» of the screws '-Iî86.
The trip, in the embodiment illustrated„is formed
y20 of wire and is provided with an eye l24 at the
lower end thereof receiving the screw. The wing
nut IIl'Iy may be tightened -to secure the trip in
«adjusted position.
In Figs- 3, 4, and 5, I illustrate the details of
the picker or pickup finger which comprises an
L-shaped bracket member .21 -fix'edly secured to
belt 22 on the outer side or surface thereof by
rivet 28. The bracket 21 forms a support for a
tiltable > finger 29, the finger being pivotally
i130 mounted on the bracket by means of a pivot pin
v3|! extending through the ñnger and bracket. A
spring 3I encircling the pin and ¿bearing-at its
opposite ends against bracket 21 and'flnger 29,
respectively, serves to maintain the same in op
erative position whereby the ñnger 29 will en
gage va hole II in the rearmost cardof the stack
when the finger is presented to the card by
"belt A22.
Spring`3| is a relatively weak one, its purpose
'being merely to return the vfinger to operative
vr'or erected position, and it is sufliciently weak to
'be -overcomefby the weight of the cardf3.
In order to 'hold finger 29y rigidly'while the
same "is lifting the rearmost card `3 and trans
porting thesame 'forwardly and upwardly during
the upward travel of -ñnger >29,-I provide a `rbolt
or detent member 32in the form of a forward
1y curved tongue overha‘nging the innergend 33
»of finger 29.
The bolt >member is pivotally
»mounted’in a pair of downturned wings'or ears
T34 integral with bracket 21 and .has integral
therewith a rearwardly extending arm '35 which
»engages the trip member 23 as the ñngerreaches
-the discharge position. VTorsion spring 3B sur
. rounds `the pivot of bolt member -3.2, urging the
same 'to latching engagement with the inner end
433 of finger 29 by `theengagement of the center
portion ’31 andV ends 3’8'of the spring with the
'-ï=bolt 'member and wings 34, respectively.
From 'the preceding description, it will be seen
` that ’when ‘the finger vtravels downwardly and
engages a lug 39 offset from trip 23, with the re
sult that arm 35 is rocked downwardly by the
trip, as illustrated in dotted lines in Fig. 5. This
releases the latching action of bolt member 32
and finger 29 is left unsupported except for
spring 3|, which was stated to be- insufficient in
strength to sustain a card 3. 'I‘he finger is ac
cordingly rocked downwardly, or in clockwise di
rection as viewed in Figs. 2, 3, 4, and 5, with the
result that card 3 drops oif the forward end of 10
the finger into position in front ofthe pack of
cards 3 and past the blade spring retaining mem
In this manner, any number of cards may be
successively exhibited at opening 2, in a wide 15
variety of shapes and sizes, the number of fin
gers 29 being as desired. It will, of course, be
clear that sadjustments for the position of iin
`gers .5 with corresponding adjustments of the
motor and belt and alteration of the position of 20
release trip'23 maybe made/as desired 'to accom
modate varying numbers of cards.
»For .the purpose of illuminating cards which
.are displayed, I provide >electric lamplß at a
suitable .point Within the casing. Due to the ac 25Y
tion ofthe pickup ñngerin elevating, advancing,
and dropping successive cards 3, it will `beffound
that an unusual lighting effect characterizes
the dev-ice of :my invention. Fingers v29 may -be,
so' proportioned as to tilt the whole pack of 30
>'cards 3 forwardly during the time that the fingers
are in engagement with :the ‘cards andjwhile
they are passing into opening-II. This will result
in a sealing or partial sealing of ’the opening
2, cutting vofi’ -light from .the exposed face ofthe “
front card.
As soon >as the rearmost card has
been removed, however, and elevated, the pack
kof cards'3 ¿falls backward against the rear sup
porting fingers.5,-allowing the light from lamp ‘540
to illuminate the foremost of the cards for >a
predetermined period Ibefore being again cutoff
in the .manner described.
This will produce a
blinking or'intermittent veffect which is certain
to attract attention to the display device lvand
the cards exhibited thereby.
"From the foregoing description, it will be ap
parent that `I have provided `a -device which is
simple in construction, efficient and unfailing in
action, and 'which permits fthe exhibition ofcards
of relatively large dimensions due to the fact
that nothing'other than `the engagement vof the
lpickup linger inïhole II is employed Vfor elevating
and dropping the cards. My invention elimi
nates .the -n’eed for picker frames and other
cumbersome details characterizing devices which
are known in the Íart.
