of breakage should be prevented, and this*
result is accomplished by reason of the re-
silient nature of the separators 18.
In the modification of my invention shown
5 in Figs. 2 and 4, a sheet metal back 24 is
provided and at its ends has the apertures
25, through which the bolts 26 pass in order
to hold the abutment members 27 in posi-
tion. At the upper and lower edges of the
10 back 24 are provided -the guideways. 28,
similar to the guideways 14 shown in Fig. 1.
The plates 13 and 21 are held in position by
the guideways 28 and are separated from
each other by, the separators 18, which are
15 of exactly the same construction as the sepa-
rators 18, shown in Figs. 1, 3 and 5. In
assembling the numbers used in connection
with the number pad shown in Fig. 2, one
of the abutment members 27 is first fastened
20 to the back. 24. Plates 13 and- 21 and the
separators 18 are 'next placed in position.
Finally the second abutment member 27 is
fastened to the back 24, having been forced
inwardly to a sufficient. extent so that the
25 side members 20 of the separators :18 are
forced toward each other, thereby maintain-
ing the latter under pressure.
It will be apparent to those skilled in the
art, that many changes could be made in
30 the detailed construction of the . various
parts which I have described without de-
parting from the spirit or scope of nMy in-
vention as set forth in the claims.
What I claim is:
35 .1. In. a plate retaining device, the combi-
nation of a frame having parallel guide-
ways thereon, a plurality of plates engaging
said guideways, abutment means at the ends
of said series of plates, and resilient sepa-
40 rators between adjacent plates, each of said
separators. comprising a front portion andspaced side members adapted to be forced
toward each other by lateral pressure, sub-
stantially as described. -
. 2. In a plate retaining device, the combi- 45
nation of a frame having parallel guide-
ways thereon, a plurality of plates engaging
said guideways, abutment means at the ends
of said series of plates, and resilient sepa-
rators between adjacent plates, each of said so
separators comprising a front portion and
channel-shaped side members normally sep-
arated from. each other, but adapted to be
forced toward each other by lateral pres-
sure, substantially as described. 55
3. In a plate retaining device, the com-
bination of a frame having parallel guide-
ways thereon, a plurality of plates engaging
said guideways, abutment means at the ends
of said series of plates, and resilient separa- co
tors between adjacent plates, each of said
separators comprising a front portion and
channel-shaped side members normally sep-
arated from each other, but adapted to be
forced toward each other under lateral pros- 65
sure, the front portion of said separator be-
ing removed at the ends of the latter, where-
by the said ends may be inserted in said
guideways, substantially as described.
4. In a plate retaining device, the coinbi- 70
nation of a frame having parallel guide-
ways thereon, a plurality of plates engaging
said guideways, a resilient abutment mem-
ber at one end of said series of plates, resil-
ient separators between said plates, and a 75
removable abutment member at the oppo-
site end of said series of plates, substantially
as described.
