The embodiment of the invention illustrated by
these drawings is a sound-reproducing instru
ment or graphophone whereby any selected one
of a plurality of circular disk records of different
diameters may be transferred to the grapho
,phone’s turntable and “played” thereon, or either
selected side of a double record may be played,
whereupon the record disk is returned to its
original position in a rack or holder, such selec
40 tion being independent of the order in which the
disks are arranged in the rack.
The illustrated mechanical and electrical or
ganization, and the operation thereof, are as
follows:
-
Referring now particularly to Figures 1 and 2,
the base or frame ii of thestructure has a‘hori
zontal top 2 and a platform 3 parallel therewith
and rotatable in alternately opposite directions on
supporting rolls 4 about a vertical axis concentric
50 with the record-carrying turntable I.
e
-
A shaft 23 has teeth forming a pinion ll near
concentrically with the platform's axis of rota
tion.
The teeth of this rack extend (as seen in Fig
ure 1) along its opposite (upper and lower) sides,
for rotating the platform in opposite directions,
and around the end portions connecting said sides.
Said shaft 23 bears turnably and also lateral
ly-slidably in a vertical slot 28 through the down
wardly extending arm 21 of the platform 3. As
shown in Figure 1 the rack 24 is centrally mount
ed in an oblong recess 25a formed in the face of
the stationary bracket 25; and the shaft 23 has
a reduced end portion 23a which remains in con-A
tact with the walls of the recess and thus holds
the teeth of the pinion’ 40 in mesh with the
teeth of the rack. This causes the pinion II to
travel around on the rack as the shaft 23 is ro- '
. tated and move the platform back and forth
through the connection of the depending arm 21,
secured to the turntabledn which the shaft is
vertically guided. To render. this shaft sum
ciently ?exible, its inner end has a head 2|
through whose angularly spaced bores 20 slidably

This platform and all the parts carried thereby
may be lifted and removed entirely from the
base or frame of the structure (for making re
pairs and replacements or other purposes), the
machine's vertical main shaft Ill being remov
ably seated in a socket H in the upper end of
its coaxial driving shaft i2 (rotated as by an
electrical motor indicated at H in Figure 31),
70 this shaft Ill being turnable in said socket
against a spring-pressed member i3 engaging
its ?attened side, in case a stoppage occurs in
the driven mechanism. The turntable is keyed
at iii to a shaft ll aligned’ with the main shaft

movement is effected by the following mecha

The gear 8i (see Figure 1) meshes with and
drives gear 38 on shaft a whose worm 4| meshes
with a worm gear 42 on a shaft 43. This shaft 70
(see Figures '7, 8, 9) carries a cylindrical drum
composed of a plurality of circular disks ll (twen

each record side of each disk recordinthe'record

For the playing of each record ‘these cam disks go

In the armature lever’s movement to dotted
line position (Figure 8) it contacts the horizontal
bar 210 (which extends along all the armature
levers in the same relation therewith) and thus
swings arm 21! toward the dotted line position
20 seen in Figure 8 and the other arm~213 toward
the right hand side of Figure 1. This action
swings lever arm- 214 and thereby the mercury
switch 216 to closed position, thus closing the
main circuit 253 containing the motor (this cir

The same movement of lever arm 213 carries

A horizontally disposed record-supporting
member 262 is moved in its longitudinal direction
through the hole 263 in one (266) of said plates
and into the central hole 264 of the record by the
inserting movement of the record into its com
partment. This member 262 is formed at one
end of a lever or rock member 266 pivoted at 266 10
on said plate to swing in a plane at right angles
thereto, and is pressed by a spring 261 to‘ the
position seen in the two right hand compartments
in Figure 29; but when a record is inserted, the
record engages the opposite end (which is a 15
spring 266) and presses this rock member or lever
265 to move the supporting member 262 through
the holes 263 and 264 as seen in the two left hand
compartments in this view, thus supporting the
records with their holes 264 in a level line curved 20
