^ Filed Aug. 9. 1926 IN VEN TOR.

Patented June 24, 1930 UNITED STATES PATENT OFFICE MUTE ' Application flled August 9, 1926. Serial No. 128,226.

This invention relates to improvements in mutes.

The principal object of this invention is to devise a modifier for use in instruments' such as horns and the like.

Another object is to provide amodifier which will produce a much better tone than is now produced with the commercial form of modifier.

A further object of this 'invention is to produce a modifier which is simple, cheap to manufacture, and therefore well within the purchase price of the average user.

Other objects and advantages will be ap- 15. parent during the course of the following description.

In the accompanying drawings formmg a part of this specification and in which like numerals are employed to designate like parts throughout the same,

The figure illustrates a cross-section of the horn bell having my modifier positioned therein.

It is a well known fact that a modifier changes the quality of the music issuing from the instrument being played, and in many instances the modifier will cause the quality of the music to be changed, even though it produces the tone desired. I

3 In the accompanying drawings wherem for the purpose of illustration 1s shown a preferred embodiment of my invention, the

numeral 5 designates the bell of a horn, such asa trombone, cornet, or the like instrument, and the numeral 6 designates my modifier positioned therein.

This modifier may be made of plastic matef'ial and is preferably cast.

passage is spirally formed and provided with an inlet port 8 and an outlet port 9. This spiral passage is made to simulate the spiral passages found in a seashell.

continuous throughout the length of the device with one end of the passageway centrally located at the small diameter of the modifier, namely, adjacent the inlet port 8 while U the end of the passageway is positioned at Within the modifier 6 is la passage 7, whichv the larger diameter of the modifier and is offset relative to the center inlet port 8.

The construction thus described results in a modifier which when placed in the horn and frictionally held therein will cause the tone issuing therefrom to be muted to a quality which is pleasing to the ear, in counterdistinction to the harsh tones produced with the modifier now upon the market for use with the said instruments. i

It will thus be seen that I have provided a modifier which is neat in appearance and one which will efliciently accomplish the objects set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the size, material, Shape and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claim.`

Having thus described claim:

A muting device embodying in its construction, a plastic truncated cone body, having an internal spiral assage-way formed therethrough, one end o the passage-way being centrally located at the smaller diameter of the body portion and the other end being positioned at the larger diameter of the body portion. i

In testimony whereof I aflix my signature.
