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
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.
A shaft 23 has teeth forming a pinion ll near
concentrically with the platform's axis of rota
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

The top 2 of the structure has angularly spaced
threaded stops I ‘I, I52 marking the limits of the
oscillation of’the platform 2. On the upward
extension I "of platform 2 is pivotally mounted
at III a catch Ill whose swinging movement is
limited by screw stops I". (See Figure 13.) A
spring ‘II. extending between this .catch and the
member I" causes said member to slide one way
or-the other depending on which way the catch is
turned on its pivot I58. If the platform 2 be

bar I14 swing together and the tone arm is swung
thereby to a position in which the stylus is over 55
the beginning of the groove of the large diameter
record and ready to be lowered thereunto. It will
be seen that by this mechanism the stylus is in

by the master switch 264 to operate the motor,
and the button switches 61 corresponding to the

action of the machine as hereinbefore explained
causes the energized magnet 66, or 621 (corre
sponding to one of selected records) to swing its
armature lever 64 to the dotted line position seen
in Figure 8 whereupon the rotation oi’ shaft 42
causes the corresponding lug 41 to engage its

this ?rst record to be played thus corresponding
to the ?rst one of the lugs which by the turning
of shaft 43 is brought into operative engage
ment with its trigger.
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
25 cuit's master switch 254 being already closed).
The same movement of lever arm 213 carries

of the record.

through the hole 263 in one (266) of said plates

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
