PORTABL PHoNoGRAPH.

Application mea March 3, 1924. seriarNo. 696,446.

To all whom it may concern: Be it known that I, SOLOMON SACHS, a

lcitizen of the United States of America, re-

phonograph of this character which makes use of the container as a sound box, in other words, the portion or space which is occupied by the various parts of the phonograph in transportation may be used as an ampliler when the phonograph is set yup for operation.

A'further object is to produce a tone arm which will close the compartment' in the phonograph when the same is being carried.

Other objects are to provide a portable turn table, and tone arm, and reproducer, which can be carried inside the phonograph when the samejs not in use.

Referring to the drawing wherein I have shown a preferred embodiment of my invention, Y

Fig. 1, is a top plan view of a portable phonograph made up to represent the conventional fiat pocket camera, the parts being shown dotted,

Fig. 2, is a view in side elevation, the

parts thereof being shown in section` of the phonograph in position for use, the parts p thereof being v.shown inl their relative ,operating position, l Fig. 3, is a section on the line 3 3 of Fig. 2, and shows the interior of the tone arm,

Fig. 4. is a top plan View of the motor4 endof the phonograph 'showing a turn table in open position thereon, the dot anddash lines showing the position assumed by the arms of the turn table when the same are folded, i y

Fig. 5, is a View in perspective of a'modified form of mounting for the reproducer in this instance, the tone arm being dispensed with and an eXpandible supporting arm being used together with a slidable side piece forthe phonograph, FFig. 6, is a section on the line 6-6 of Fig. `7, is a section on the line 7--7 of Fig. 5, Aand i Fig. 8, is a section on the line 8 8 of Fig. 5.

Referring to the drawing in detail, 5 indicates the housing for the phonograph parts which is so shaped as to simulate the pocket type .of fiat camera having the rounded ends 6, and a carrying strap 7 In one end of the housing or container 5, there is fixed a suitable motor 8, the shaft 9 of which projects up through the top of the casing to receive a turn table 10, u on which may be mounted the usual recor 11.

The reproducer 12, is carried on the end of the tone arm13, through the medium of an inwardly extending flange 14, in said tone arm in which the tubular portion 15 of the reproducer frictionally lits.` The tone arm has formed in one end thereof, the vertical pipe 16, the lower end of which is beaded as at 17 lto limit the. downward movement .of the pipe in the casing opening 18.

This opening 18 leads into thev storage space for the parts and when the parts are in operating position, it can be seen that this space will act as an amplifying chamber for the sounds emitting from the tone arm 13, the end of the tone arm is suitably rounded to match the rounded end 6 ofthe casing 5 so that when the same is placed in position against the loifset 19, in the motor housing, the same Will completely close the side of the phonograph and will retain in the sound box the reproducer 12 and turn table 10.

.The tone arm is provided with suitable deectors 20, opposite the openings therein so that the tone is conveyed directly' into the sound box.

The turn table is composed f a suitable disk l21 having a fixed arm 22, and two pivoted arms 23, the latter of which when not in use may be folded down parallel to the arm 22 so that it can 'be seen that the turn table will occupy little space and may be stored in the sound box as shown in Fig. 1.

It is apparent also, that the loose connection of the pipe 16 in the casing 5 permits4 of vertical movement of the reproducer 12, while the bead 17, permits of rotary movement of the vreproducer.

This combination tained,

provides Athe universal movement necessary to efficient operation of a reproducer.

In F ig. 5, ll have shown a method of supporting the reproducer which consists in providing the housing 5 With a sliding side member 24:, which normally closes the side of the empty portion of the phonograph, in this instance, this unoccupied portion not being used as a sound box. At the end of this slide 24, ll provide a bracket 25 into which the end of a telescopic arm 26 is re-y thel forward end thereof being grooved annularly as at 27 and being adapted to fit into an extended tube portion 28 of the reproducer 12,-this tube portion being provided with an opening 29 through Which passes a spring pressed pin 30, the pin engaging the groove 27 to hold the reproducer in position on the end of the arm. The reproducer carries, in this instance, the sound box or amplier which is made up of a hemispherica1 shell member 3l of celluloid or the like, having an extended neck 32 which fits into the usual opening or tube 15 of the reproducer. The amplifier is provided With an integral preforated cover 33, having suitable openings 34; therein. A disk member 35 is disposed beneath the cover 33 and is revolvably held thereagainst through the' medium of a thumbv nut 36, this disk being also provided with openings to match the ones formed in the cover, so that a revolving mbvement of the disk Will 'vary the volume of the sound emitted.

lln this construction, it is evident that the ampliier may be made shallow enough to t into the housing and the supporting arm 26 may be also telescoped so that it may be neoaoeo placed in the `housing together with the reproducer.

lln Fig. l, when the tone arm has been placed in the position shown to close the opening of the casing, ll may provide suitable latch members 37 to retain the same in this position.

llt Will be seen theretore, that ll have provided a portable phonograph Which can be carried in the pocket after the manner of the pocket camera, and one which Willhave few parts, which may be quickly assembled and will operate efficiently.

Having described my invention, what ll claim is:

l. A' portable phonograph comprising a flat camera-like casing, a sound amplifying chamber in said casing having an open mouth, a tone arm for said phonograph, said tone arm when not 'in use being adapted to serve as a closure for the mouth of said chamber.

2. A portable phonograph comprising a casing having a portion constituting a sound amplifying chamber terminating in an open mouth, said casing having an opening through one side thereof in communication with said sound amplifying chamber, and a tone arm communicating With said chamber through said openingand adapted to serve When not in use as a closure for the mouth of said chamber.

lln testimony whereof ll hereunto adir my signature.
