UNITED STATES PATENT OFFICE.

.ADOLPH A. THOMAS, 015 NEW YORK, N. Y.

COMBINED RADIO AND Application filed February My invention is for a combined radio and phonograph cabinet constructed to constitute a single pieceof household furniture containing complete radio-receiving apparatus and phonographic reproducing mechanism. The amplifying horn of the phonograph mechanism is also utilized for the loudspeaker of the radio set, and there is means for acoustically connecting either mechanism with the horn by merely adjusting a finger piece conveniently located on the cabinet. This finger piece, which may be simply a knob on the phonograph motor board or the radio panel, controls an acoustic valve mechanism in the cabinet for readily connecting either the tone arm of the phonograph or the telephone receiver of the radio set with the amplifying horn. No removal of the phonograph sound box or any other parts is necessary to use the phonograph horn as an amplifier for the radio set. In its preferred form, the acoustic valve mechanism of my invention also performs the function of controlling the volume of sound issuing out of the horn either from the sound boX or from the telephone receiver.

The foregoing and other objects and advantages of'my invention will become apparent from a detailed description of the accompanying drawings, which illustrate a cabinet embodying the features of my invention. In these drawings,

A cabinet K, of any approved construction and design, contains phonograph mechanism P and radio receiving mechanism R. It will not be necessary to describe either of these mechanisms in detail, since they are well understood and are purchasable in the open market in various forms andstyles. So it will beunderstood that P represents any is an enlarged fragmentary view the controlhng valve in various IPHONOGRAPH CABINET.

suitable phonograph mechanism installed in the cabinet, and R is any practical radio receiving set.

In the particular instance illustrated, the cabinet has a right compartment 1 and a left compartment 2.

Doors

1 and 2, respective ly, may be provided for these compartments. The right compartment 1, which houses the phonograph mechanism, has a top panel 3, usually called the motorboard, from the fact that it supports the phonograph motor. Compartment 1 also contains a sound-amplifying horn H of suitable construction and design, and acoustically connected with the tone arm in the usual way. The horn H, as in all standard or accepted makes of phonographs, is rigidly built into the cabinet.

The left compartment 2 is for the radio mechanism. A top panel 4, preferably in line with motorboa-rd 3, may support the adjustable hand members of the tuning units contained in the radio set. Or, if the radio parts are mounted in a box with a vertical front panel, the entire outfit may be placed as a unit in compartment 2, leaving the front panel of the box at the open front of the compartment for easy manipulation of the finger pieces projecting from the panel. It is immaterial how the radio set is mounted in the cabinet.

The radio set in the cabinet includes a telephone receiver S of suitable construction. There are many kinds of such receivers on the market, and are well known to radio enthusiasts, so I need not describe the detailed construction of receiver S, which represents more or less diagrammatically any practical form of radio telephone receiver. I will now describe how the receiver S may be readily connected with horn H without removing or even disturbing the sound box of the phonograph mechanism.

In the neck 5 of horn H is provided an opening 6 over which is secured a plate 7, as by screws 8, or otherwise. Plate 7 has a cylindrical flange or extension 9 adapted to receive the end 10 of a suitable sound tube A. Preferably the end 10 of the tube is enlarged, asshown in Fig. 4;, so that flange 9 of plate 7 forms substantially a continuation of the inner wall of the tube. The other or smaller end of tube A is connected to a pipe 12 mounted in the partition 13, wiich separates

side the cabinet. It is obvious that the practical advantages of my invention are fully realized in a phonograph cabinet equipped with my novel means foracoustically c011- necting a telephone receiver With a phonograph horn, irrespective of where the radio set is situated. 7

It will be seen from the foregoing that I have provided a simple and convenient means for untilizing the horn of a phone'- graph cabinet as a loudspeaker tor a radio set without the trouble of having to remove the sound box. A little twist of knob 21,01 whatever kind of finger-piece may be used, is all that is necessary to connect either the tone arm or the radio telephone receiver with the amplifying horn. By bringing the small end of tube A out near the front of radio compartment 2, the receiver S is in a handy position. for removal and replace ment.

If desired, the cabinet may be made entirely self-contained as a'radio cabinet by providing it with a receiving loop.

Although I have herein shown and described a specific construction, I Want it understood that I have done so merely to e20 plain my invention by means of an illustrative embodiment, and not by way of restriction or limitation.
