found that it is very essential for perfect func

Referring to the drawings for a more detailed

the machine locks up due to the misalignment of

cates the frames or holders into which the display
sheets are secured and which are slideably re
20 tained on upper and lower tracks 8, which form
a closed circuit. Frames ‘I are normally com
pacted to form a magazine along a portion of the
track 8, see Figs. 5 and 6. Two parallel bars 9
and Hi, see Figs. 3 and 4, are fulcrumed on lower
25 ?xed bearings, H and I2 respectively, the upper
extremities of the bars 9 and H) are likewise ful~
crumed into a T-shaped cross head I 3, see Figs.
3 and 4, by bearings l4 and i5 respectively mak
ing in effect a closed parallelogram movement,
30 the cross head l3 always remaining in a vertical
position during its transit from the position
shown in Fig. 3 to the position shown in Fig. 4.
On the cross head I3 is secured by means of two
hinges I6 and H, see Figs. 3, 4, and 5, the swing
35 member or pusher |8, as well as the swing lock
l9, the bar 80 ties the top and bottom arms,
which compose the swing lock l9, rigidly together.
Looking at Fig. 5 and at the phantom drawing of
the elements l6, l8, and IE3 at the left end of the
40 drawing showing these elements at the extreme
left position, at which point they pick up frame
A, it is readily seen that the element l8 under in
?uence of torsion spring 2|, see Fig. 3, which
keeps the extremity of the pusher i8, recessed in
45 to the bottom of the U-shaped frame A while the
lip 22 of swing lock l9, also under in?uence of
spring 2|, bears against the forward edge of the
U-formed frame and forms a lock to prevent the
frame A from falling ahead of the oscillating arm
50 while in transit to the right extreme position
shown in full lines in Fig. 5. By virtue of the
reversal of movement of the assembly |5, |8, and
I9 at their position at the extreme right position
in Fig. 5 the edge 24 of frame E forces the pusher
element |8 to recede inwardly and coincidently
and B with C the succeeding frame; 3| is the
locking arm which may be integral with or rigidly
attached to the locking gate slide bar 32.
Slide bar 32, see Figs. 3 and 4, is retained by
pins 33 which act as crossheads moving in slots
34. On arm 35 secured to slide bar 32 is attached 20
spring 36 which is secured under slight tension
to the chassis or panel 21 at 36a so that normally
element 32 is retained in the lowered position as
seen in Fig. 3. A cam lever 39, see Fig. 4, ful
crumed on panel 2'! at 40 is connected to slide bar
32 by virtue of the pin 3'5 secured to bar 32 which
slides in slot 38 cut in cam lever 39. A pin 42
on parallel bar it is so positioned that it contacts
with the cam surface 4| on lever 39 just before the
oscillating elements have arrived at the position 30
as is shown in Fig‘. 4, the contact of pin 42 with
cam surface 4| elevates the locking slide bar 32
with its frame locking arm 3|. This movement
is speci?cally shown in its relationship with
- frames A, B, and C in, ?rst, Fig. 10 wherein frame 35
A is locked due to locking bar 3| contacting the
U shaped side wall of frame A whereas when
slide bar 32 is-elevated by the above described
action the bar 3| is then shown in its elevated
position in Fig. 11 now having registered with
aperture 5| in frame A and frame A has started
to move away. As slide bar 32 again is lowered,
due to spring 35, and also as an additional safe
guard by pin 42, contacting with cam surface
4|a on lever 39 positively lowering bar 32, lock 45
bar 3| has again been lowered and has passed
through opening 38 in frame B, allowing frame B
to reach a registering position in the circuit as
shown in Fig. 11, as and when during the oscil
lating mechanism transit to the left as seen in 50
Fig. 3 the following described mechanical pusher
mechanism has forced forward all frames in the
compacted magazine from the point Z, see Fig. 7,
it is noted that the cam arm 25 see Fig. 3, secured
to frame A therein. This movement which is
chosen at this approximate point Z is essentially 55

thus the lip 22 has been positively forced away
from looking contact with the U-shaped frame E
on the motor and is accomplished as follows:

65 locked and is positively retained in the position
as shown in Fig. 3 by the retaining action of the
spring actuated pawls 28 and 29, see Fig. 5. Turn
ing now to Fig. 4 wherein the oscillating arms 9
and i5 are at their opposite extreme positions due
70 to the angle of its contact with the edge of frame

and carrying a particular frame 9E! in its transit,
which frame fill, still securely held by, pusher pawl

hence forces all the remaining frames forward,
15 thereby dividing the magazine resistance into two
distinct and succeeding movements, the ?rst, pro
duced by cross head element 50 and having com
pleted its movement, dividing the magazine before
the last movement begins; in this manner the
motor load is reduced in contrast as if all the
frames but one, for registration purposes, were
moved at one time by the'motor. Transverse
springs 63 and 69 are positioned across the top
and bottom of the un?lled portion of the circuit
25? to ‘prevent the isplays from falling inward across
the path of a succeeding display movement.
The operation of the machine is clearly under

the displays, at one extremity of its movement

always remain aligned to the display or frame in
question while in transit, the elements 18 and 22

as they follow the arc of the voscillating movement.
As the oscillating movement moves to the left
it relocks frame B, see Fig. 11, and moves the
compacted frames in the magazine forward the

.
It should be noted that if the load (motor
3 torque) card is studied of this type of display
machine, there is seen to be a very sharp “peak
load” at the one point in its cycle where the dis
plays compacted in the magazine are all advanced
together along the circuit, a step essential to reg
istration with the window. This movement calls
for a motor of unneeded size, cost, and weight
for the operation of the rest of the cycle which
consists of moving a single display across the
show window, Therefore, my invention em
braces means to very materially reduce this
“peak load” by spreading it in two or more se
quential movements of the magazine and is a
valuable contribution. It should also be observed
65 that this procedure is essentially different from
advancing one or two displays in the magazine
for proper registration as such a step does not
reduce the peak load and accomplish the desired
result.
