COMBINED PHONOGRAPH AND RADIO REGEIVIN G APPARATUS.

Applicationfiled June 30, 1924. Serial No. 723,116.

This inventionfrelates to a combination radio and phonograph apparatus and has for its primary object to provide means for employing a single amplifying horn with either the radio apparatus or the phonograph, as may be desired.

Another object is to provide means for changing over from use of the one apparatus to the other by a simple niianipulation of a knob or handle on the outside of the cabinet. i

In. the drawings in which I have shown one embodiment of my invention,

Fig. 1 ma front elevation of a cabinet in which my invention maybe embodied.

Fig. 2 is a front elevation of a part of the apparatus shown in dotted lines in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1. I i

Fig. 4 is a section on the line 44, of Fig. 2, and

Fig. 5 is a of Fig. 2.

As is well-known the use of radio receiving apparatus is widespread as is also the use of phonographs. One of the important considerations of a radio receiving set is the question of space and another consideration is the question of a proper amplifying horn. A horn which will give good results is expensive and it is therefore my purpose to economize space and to make a single amplifying horn to serve for both a radio receiving set anda phonograph and thereby make it possible to mount both ofthe above instruments in a singleqcabinet, which may, of course, be made an ornamental piece of furniture.

Referring now to the drawings, 1 designates a cabinet of any suitable construction. Contained in said cabinet is a radio receiving device indicated generically at 2 and a section on the line 55 phonograph indicated at 3 and comprising the usual. turn-table 4, sound reproducer 5 and tone-arm (5. The tone-arm 6 is mounted on the motor-board 7 and is connected to the amplifying horn 8 beneath the motorboard, by means now to be described. Connected to the bell mouth. of the horn 8 by any suitable means is a tubular, T-shaped neck 9 having arms 10, 11 and 12.

The arm 10 is connected to the horn in any suitable manner and extends upwardly and from said horn, and at its upper end it is -mounted in the sleeve 13 is a valve 16 comprising a tubular member having walls 17 fitting within said sleeve 13 and also provided with an elbow 18 having an end 18 registering with the arm 10 and an end 18 registering with the arm 12 or with the arm 11. i

It will be seen that the end 18 provides a contmuous passage to the arm 10 and so to the amplifying horn, While the other end 18 of the elbow may provide a passage to the arm 11 or 12, as may be desired, it being understood, of course, that the openings in the arms 11 and 12 are of the same size as the opening in the end 18 of the elbow. Therefore, a continuous passage may be provided from the horn to either the phonograph or the radio loud speaker, as may be desired, by merely turning the valve 16 from the position shown in Fig. 2, where it forms a passage between the phonograph and the horn to a position diametrically opposite thereto where it will furnish a passage from the horn to the radio loud speaker.

In this embodiment of my invention I provide means on the outside of one wall of the cabinet, as the wall 14, for example, to

operate the valve and this means may comprise a knob or handle 19 connected to a rod be apparent to those skilled in the art.

It will be seen that the sleeve 13 has its end parallel to the wall 14, that is, its end I Front the above it Willi be'evident' that I have: provided. a means for using an. amp1itying horn with; either a phonograph or a outfit, as may' be desired, the changing over: from one to the other being easily effected by a simple adjustment trom the! outside of the cabinet, and without necessiataming; even. so" much as! the; lifting ot the cover on the cabinet;
