F 1 is a front elevation. of-"a phonograph cabinet embodying one form of the present -invention;

F-ig '5 is a detail plan view of the cabinet showingthe tone arm of the phonograph con nected througlr the medium of' an adapter with the radio receiver 1 In phonograph cabinets as'previously constructedit has been usual to divide the cabinet space into two compartments through one offwhich the sound amplifying horn passes to anopening at the front of the cabinet.

The other! compartment is commonly employed forstoring records. In cabinets of the console type the two compartments are arranged side by side, while inupright cabinets the two compartments are arranged one above the other; 1

The present invention contemplatesthe location of the tone amplifying horn within the compartment" in which the records are stored and inthe' embodiment shown the horn 'is placed in there'ar of the record space.

horn is preferably given anfimproved form, aswill be described, to improve the tone effect and tow better fit within thespace provided in the rear ofthel record space." This leavesthe remaining compartment free for other uses.

i This additional spacewis especially desirable for-combined" phonograph and radio apparatus since the-receiving apparatusmay; belocated in the additional sparseprovllded by-the The 2' 7 and, 28 and above these walls are additional deflector plates 29 and 30 which have 1924. Serial 119113.426.

present arrangement and the amplifying horn if desired maybe used as a loud speaking connection for the radio apparatus.

In. the. drawings, the numeral 10 designates generally a cabinet of the console type having a compartment 11 provided with shelves 12 on which record albums may beplaced; .The compartment 13 is left free for, the location of radio apparatus or such other. use as may bedesired. The usual form of motor 14 having a crank 15 is mountedin the space above the shelves 12 and drives the turntable 15, for the phonograph records.

y A hollow pedestal 16 is mounted on the top wall 17 which covers the compartments l1 and 13 and the usual tone arm 18 is pivoted toswing. about thevertical' axis of the pedestal 16 in the usualmanner; The tonearm 18 carries the usual reproducer 19; The top wall 17 has an opening 20 therethrough which registers withthe interior of thepedestal 16 and a downwardly extending horn 21 registers with the lower face of the opening 20 and extendsdownwardly in. the rear of' the shelves 1 2. The horn, 21 is flared-so that it gradually increases in cross-sectional area from top to bottom and is preferably made rectangular in cross-section to more economically fitthe space in the rearof the shelves 12'and to produce: desirable sound amplificas tiona snrroundingthe lower end' of the horn 21 1s a casing 22which is also preferably rec- .tangular in cross-section and elongated to substantially. filltthe space in the rear of the 'shelves'12; The casing 22 is provided with a deflector plate 23 located beneath the lower end of the horn 21 and provided with a cen- .tral rib 24c and laterally extending curved faces 25v and 26 to divide the sound waves and direct them in two courses, laterally and upwardly. The deflector plate 23 is continued upwardly to; provide partition walls curved. faces deflecting the sound waves downwardly through passages 31 and 32 wh ch penthr gh. thebottom of the cabns p V q It should be noted that the cross-sectional area of the tone passage gradually increases throughout the entire length of the passage and that the double passage at the point where the sound leaves the end of the horn 21 provides a combined cross-sectional area which continues to provide progressively increasing expansion of the tone passage. In this way great amplification of the sound is produced and the quality of the tones is preserved.

It will be seen that the present invention not only provides an improved tone passage, but affords greater economy in the arrangement of the cabinet than has heretofore been secured, thus making it possible to accommodate two sets of instruments in a cabinet of a size practically the same that has heretofore been employed for a single instrument.

In the embodiment shown in the drawings, a radio receiving apparatus is indicated at in the chamber 13. The receiver for this apparatus may be connected to the tone arm 18 in the place of the reproducer 19 so that the amplifying horn 21 serves as an amplifying medium either for the radio receiving apparatus or for the phonographic reproduction apparatus. To adapt the amplifying horn 21 to the radio receiver the reproducer 19 on the tone arm 18 is removed and replaced by a s-o-called adapter 33 which is wired to the radio receiver by cord 34. Any conventional type of adapter may be used for this purpose.

It will be understood that various changes in details may be made by those skilled in the art without departing from the spirit and scope of the invention and I therefore do not wish to confine my invention to any specific form, except as defined in the appended claims.

I claim 1. A phonograph cabinet comprising a pair of chambers arranged side by side, sound receiving instrumentalities located in one of said chambers, phonographic reproduction mechanism positioned above the other of said chambers, and an amplifying horn extending downwardly in the rear of said lastmentioned chamber and adapted to be selectively connected to either the sound receiving instrumentalities or the phonograph reproducing mechanism.

2. A phonograph comprising a pair of chambers arranged side by side, radio receiving apparatus positioned in one of said chambers, storage shelves arranged in the other of said chambers, phonographic reproduction apparatus arranged above said last-mentioned chamber, and an amplifying horn adapted to be selectively connected to said radio receiving apparatus and said phonographic reproduction apparatus, said amplifying horn being located in the rear of said shelves and opening downwardly through the bottom of said cabinet.

3. A sound reproducing instrument comprising a cabinet having a storage compartment at one side thereof, an amplifying horn arranged in the rear of said compartment, a reproducing instrument positioned above said storage compartment, and a reproducing instrument of a different character arranged at one side of said storage compartment said amplifying horn adapted to be selectively connected to one or the other of said instruments.

4. A sound reproducing instrument comprising a cabinet having a storage compartment at one side of the front thereof, radio reproducing mechanism disposed at the other side of said cabinet, a phonographic reproducing instrument disposed above said storage compartment, and an amplifying horn arranged in the rear of said storage compartment and adapted to be selectively connected to either the radio reproducing mechanism or the phonographic reproducing instrument.

5. A phonograph cabinet comprising a pair of chambers arranged side by side, radio receiving apparatus positioned in one of said chambers, storage shelves arranged in the other of said chambers, phonographic reproduction apparatus arranged above said lastnamed chamber, an amplifying horn adapted to be selectively connected to said radio receiving apparatus and said phonographic reproduction apparatus, said amplifying horn comprising a rectangular casing opening downwardly through the bottom of said cabinet, a plurality of divided sound deflectors mounted in the top of said casing, a sound horn projecting into the casing between said deflectors and terminating below the horizontal center of the casing, a deflector plate centrally disposed in the bottom of the casin with respect to the horn, upwardly presente end walls on said deflector plate terminating in a vertical plane intersecting the center 01' the sound deflectors, and a central rib in the bottom of the deflector plate axially disposed relatively of the'horn but terminating below the lower end thereof.

6. A phonograph cabinet comprising a plurality of compartments, one of said compartments being adapted to receive a radio receiving apparatus, a second compartment abutting said first compartment for use as a storage space above which is mounted a phonograph reproducing apparatus, a third compartment forming a horn having a plurality of chambers forming outlets from said horn, a common sound inlet member symmetrically arranged with respect thereto, adeflecting plate in front of said inlet arranged to deflect the sound equally to said plurality of chambers, and means connected to said inlet member adapted to be selectively connected to the radio? receiving apparatus and iii) phonograph, reproducing apparatus, said horn being arranged so that adjacent sides thereof are in juxtaposition with sides of said first and second compartments respectively.

In testimony whereof I have signed'my name to this specification on this 12th day of May, A. D. 1924.

OTTO C. SCHROEDER.
