MUSICAL INSTRUMENT.

Application filed September 8, 1926. Serial No. 134,193. l

This invention has reference to musical instruments and aims to provide novel means whereby Ythe tone of a phonograph will be greatly enhanced and the volume increased so that the noises caused by a reproducing needle passing over a phonograph record will be transposed into sound waves almost identical with sound waves produced by the instrument originally producing the sound waves recorded on the record.

An important object of the invention is to provide a plurality oi' horns of various sizes and corresponding to the sizes and shapes of the various horns or instruments of a band.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departingr from the spirit of the invention.

Referring to the drawings: n

Figure l isa perspective view illustratingr sound boxes, and a plurality of horns in communication therewith.

Figure 2 is a perspective view taken from the front of the device.

Figure 3 is a perspective viewtaken from one side of the device.

Figure 4 is an enlarged perspective View illustrating one of the sections of the device.

Figure 5 a sectional view through the horns extending into one of the sound boxes.

Figure G is a vertical sectional View through the upper portion of one of the sound boxes.

Referring' to the drawings in detail, the device includes sound tubes 5 and 6 respectively, which sound tubes are in communication with the pipes or tubes 7 that taper to their upper ends and merge into an upwardly extended tube or pipe 8.

As shown, these pipes or tubes 7 extend in opposite directions from where they extend upwardly and inwardly as clearly shown by Figure l of the drawings. The upwardly curved pipe 8 connects with the lower portion of the tone arm 9 of a phonograph so that sound waves passing through the tone arm will be directed to the sound tubes 5 and 6 through the pipes 7 and 8.

The sound tubes 5 and 6 are circular in formation and are disposed vertically, the upper `surface thereof being provided with a plurality olf openings to receive the lower ends of the horns, which horns are of various sizes and diameters corresponding to the sizes and diameters of horns used in bands, orchestras or the like, for example, the reference character l0 indicates a bass horn, which has its main or body portion 11 extended downwardly and in communication with the sound tube 5, the horn 12 being a smaller or alto horn having its pipe or tube lhextcnding downwardly and also communicating with the sound tube 5.

This principle is carried out in both sections of the device and the various types of horns used in a band'are reproduced in each section of the device, to the end that as the sound waves pass through the main pipes 7 and 8 of the device and pass into the horns, the horns that are in resonance with sound waves produced by corresponding types of horns of the band, will pick up the sound waves and pass the same into the sound box of the machine or musical instrument, to the end that the tone of the instrument producing the original sound waves will be reproduced, and the volume of the instrument will be greatly increased, enhancing the qualities of the machine tothe maximum.

While I have shown and described a plurality of horns having pipes, extending into the sound boxes of the device, it is to be understood that the number and sizes of horns may be varied without departing from the spirit of the invention.

I claim:

In a device of the character described, a pair of pipes merging into a substantially short pipe to be connected with a phonograph tone arm, said pipes having enlarged end portions defining sound tubes, plugs {itted in the ends of the tubes, said plugs having a plurality of openings, said openings being of various sizes, and horns fitted in the openings to receive sound waves from the sound tubes.

In testimony that I claim the foregoing as my own, I have hereto affixed my si nature.

EDWIN M. WEA R.
