TALKING-MACHINE.

Specification of Letters Patent.

Patented Sept. 1'7, 1918.

Application filed April 28, 1917. Serial No. 165,090.

To all whom it may concern:

Be it known that I, THOMAS HERBERT REED, a citizen of the United States, residing.

in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Talking-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, forming a part of this specification.

The present invention relates to Improvements in talking machines, especially those of the disk type.

The object of my invention is to provide such a machine as will produce a full and better tone; to impart resonance to the reproduced sounds; to deflect the sounds; and in which the scraping, metallic and discordant sounds, heretofore always, so far as I am aware, produced by talking machines, are practically eliminated, and to produce amplifying means by which the quallty and naturalness of the recorded sounds are reproduced with greater faithfulness, and also with a reduction of the co-mingled extraneous sounds which are usually present In the accompanying drawings is illustrated one form of apparatus containing my improvements, by means of which the foregoing objects are attained, and by wh ch is accomplished the new results, all of whlch will hereinafter be fully described and claimed, and which form part of this specification, and in which Figure 1 represents a fragmentary perspective view of a broken vertical section of a cabinet, showing in side elevation, my invention therein.

Fig. 2 represents a detail side elevation of the sound amplifier.

Fig. 3 represents an under plan v1ew; and

Fig. 4 represents an end elevation of the same.

Similar characters of reference refer to like parts throughout the specification and drawings.

Referring to the drawings, 1 represents the upper portion of a cabinet having hinged thereto a cover 2. The upper portion of the cabinet contains a talkmg machine (not shown), a sound arm 3 of the usual type, the lower end of the sound arm 3 be ing connected by means of a sound tube 1 to the amplifying element 5, the front portion of which is suitably secured to a curved sound board 6, which is attached-at its front upper edge to the front top edge of the sound outlet chamber 8. To the rear top edge of the sound outlet chamber 8 of the cabinet 1 is also attached a curved sound board 7, said sound board 7 being curved in a suitable manner below the open end of the amplifying element 5, and the-free end of which is secured to the front of the sound outletychamber 8 at the front of the cabinet 1.

The amplifying element 5 and sound boards 6 and 7 are preferably"1nade of a width corresponding with the width of the sound outlet chamber 8, which is the width of the cabinet.

In order to obtain the full effect of the sound reproduced, the sound outlet chamber 8 is open in the front of the cabinet 1 and usually provided with a suitable screen (not shown.) The side walls of the cabinet, one of which, numbered 9 is only shown, constitute the side walls of the sound outlet chamber 8.

The amplifying element 5 at its bottom, is provided with an approximately rectangular-shaped mouth 10, from the rear edge of which rises an approximately straight wall 11, and from the front edge of which rises an inclined wall 12, said rear and front walls 11 and 12 being connected by upwardly converging side walls 1313,' all of which terminate in a tubular neck 14, to which one end of the sound tube 4 is attached in any convenient or desired manner,

and by which the amplifying device is carried, the upper end ofsaid sound tube 4 communicating with the open end of the sound arm 3, as above previously set forth.

Along the front marginal edge of the amplifying element 5, a piece of felt 15 may be secured, to which one end of the sound board 6 is connected.

Secured within the amplifying element, between-the walls 11 and 12, and in close proximity to the mouth 10 thereof, and preferably in a straight line with the tubular neck 14 is a tubular post 16. Inasmuch as the material from which the amplifying element 5 is constructed usually consists of very light wood or metal, the interposition of said tubular post 16 imparts to the mouth 10 of-the amplifying device 5 that tension and rigidity which is essential to prevent eX- cessive vibrations of the 'wa llsof said amplifying element 5.

In order to prevent. like vibrations from taking place in the sound board 7, a similar post 17, indicated in dotted lines in Fig. 1

vention, I do not care to restrict myself to the exact details of construction, combina:

tion and arrangement herein set forth, it being obvious that minor variations thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such departures from what is herein described and claimed, I consider within the scope and terms of my claims.

Having thus described my invention, what I desire to claim and secure by Letters Patent is 1.- A sound reproducing machine comprising a main casing, a sound chamber therefor, an amplifying device located in the rear end of the sound chamber, said amplifying device comprising a chamber formed with an inclined frontand straight rear wall,' said front and rear walls being connected with two converging side walls, the said walls at the bottom forming a rectangular-shaped open mouth and at the top a tubular neck, an upper sound board projecting downwardly from the front top edge of the sound chamber rearwardly to the front edge of the mouthof the amplifying device and a lower sound board projecting rearwardly from the front bottom edge of the sound chamber and curved upwardly under the mouth ofthe amplifying device and secured to the rear top edge of the sound chamber.

2. A sound reproducingmachine comprising a main casing, a sound chamber therefor, an amplifying device located in the rear end of the sound chamber, said amplifying device comprising a chamber formed with an inclined front and straight rear Wall, said front and rear walls being connected with .two converging side walls, the said walls at the bottom forming a rectangular-shaped beveled and open mouth and at the top a tubular neck, an up er sound board projecting downwardly rom the front top edge of the sound chamber re'arwardly to the front edge of the mouth of the amplifying device, and a lower sound board projecting rearwardly from the front, bottom edge of the sound chamber and curved upwardly under the mouth of the amplifying device and secured to the rear top edge of the sound chamber.

This specification signed and'witnessed this 27th day of April, 1917.
