20 Claims. (Cl. 274-10)
This invention relates to phonographs, and has
for a general object the provision of a novel and
an improved phonograph of the multi-record
type, by means of which the records may be
5 played selectively o'ne at a time in any desired
sequence, or some ,or all of the records may be
played inseriatim or a predetermined sequence.
Another object of the invention is the provi
sion of a reliable and generally simplified record
10 changer for the above mentioned type of phono
graph.
`
A further object of the invention is to pro
vide a plurality of record carrier operating mem
bers which are selectively operable, or a plural
15 ity or all of which are successively operable
automatically to move the respective record car
riers to their record delivery positions.
Other objects of the invention include the
provision of the novel arrangements and com
'20 bination of elements hereinafter disclosed and
claimed, and as set forth in'the accompanying
ployed in the record changer of the preceding
ligure;

sulßtantially along the lines Ii--M of Fig. 1l;
and
'
Figs. l5 to 22, inclusive, are fragmentary dia

the novel record changer.
The illustrated phonograph comprises, as
shown in Fig. l, a casing or cabinet A of suitable
construction vfor accommodating a chassis or
frame B, amplifier means C, and speaker means
It will be understood that the chassis B is
adapted to serve as mounting means for the
record carrying and reproducing devices which,
generally considered, cooperate to translate the
irregularities or impulses recorded in the sound
track oi a record into mechanical vibrations and
to convert those mechanical vibrations into elec

carriers or trays J arranged one above another
in column or stack relationship and swingable t
to and from cooperative relationship with the
turntable G; and members K and L providing
individual supports for each record carrier J at
the end thereof opposite the mounting assembly

as will be seen by reference to Figs. l. 2, 4, and

driving the cam M: turntable rotating means O

the turntable G and that is movable as indicated
at Q (Fig._2) toward and away from the re

V operable from outside the casing A; and vari
ous control devices which have been generally
designated by the reference characters W, X. Y,
and Z.
Phonographs of the class to which this inven
tion relates, are usually. but not necessarily, con
trolled by coin operated means which includes,
as shown in Fig. ‘7. a slidable coin receiver 3l for
'delivering a coin to a coin slide or chute 32.
In falling down the coin slide I2. the coin en
gages a switch arm 33 and swings it about its
pivot 34 whereby to close switch contacts 35.
When the contacts 35 are closed, a suitable
source Il of electrical energy will energize the
control device W. which may be an electromagnet
adapted to operate a pawl I1 for operating a
ratchet Il of the control device X. `The ratchet
18 is provided with a pin or stud l! which nor
mally engages a switch operating arm 4l for
holding switch contacts 42 open. When the
ratchet I8 is operated by the pawl 31, the pin
39 `releases the switch operating arm 4i per
:hitting> the contacts 42 to close. ’I'he turntable
rotating means 0 is thereby connected in circuit
with a suitable source of electrical energy, dia
grammatically illustrated at 43, which energizes
the turntable rotating means O to cause it to

causing it to rotate the master cam M and its
shaft 45.

When the rotation of the master corn M is thus
resumed, the cam follower S engaging in the cam
track, and the slide R carrying the follower 8 are
moved by the cam in a direction to cause the turn
table reciprocating arm T to move the turntable
G away from the reproducer means H and back
through the positioned record carrier J whereby 15
to deposit the played record thereon. l Meanwhile.
and after the played record has thus been moved
out oi' playing engagement with the reproducer
means H, a pin or stud 54 on the rotating master
cam M engages the reproducer return means U 20
and moves it to swing the disc 49 by engagement
with its projection 5l in a direction to return the
reproducer means to its starting position.
During the rotation ofthe disc 4l. the notch in
the disc passes beyond the switch operatixm arm
52 and the periphery oi the disc cams the arm 52
in a direction to open the switch contacts 53.
The opening 'of the switch contacts Il does not.
however. result in the stopping of the cam driv
ing means N for the reason that before they have
been opened, the rotation ot the master cam M
and its shaft 45 has caused the rotation of the
notched disc 4B of the control device Z sumclently
to move the notch in that disc out of registration
