JAMES PEARSON, or BENTON, NEBRASKA.

SOUND-MODIFIER FOR PHONOGRAPHS, 800.

To all it may concern:

Be it known that I, JAMES Pearson, a citizen of the United States, residing at Demon,-

in the county of Lancaster and. State of Nebraska, have invented certain new and useful Improvements in Souml-l/Iodifiers for Phonographs, Graphophoncs, and Like Instruments, of which the following is a specification. Y

My invention relates to certain new and useful improvements in sound modifiers or mulllers, more especially for use with phonographs,-graphophones and the like.

It has for its object more particularly to simplify construction, to facilitate the application of the instrument for use, and provide for the ready and ell'ective retention thereof in position when so applied.

It consists of thedcta'iletl construction and arrangement of certain parts substantlally as hereinafter fully disclosed and defined by the drawing, being ball-like, for facility and ready application within the born or megaphone. D, as suggested 'in Fig. 2 of said drawing. It is apparent that by suitably forcing the member or mutl'ler A into the born to a greater or less extent, the sound emitted therefrom will be accordingly modified or mnllled as may be desired.

In order that the member or mufiler A may be readily or conveniently applied for use as indicated, I provide a stem' or handle B therefor, forming said stem or handle of a continuous piece of wire bent about centrally upon itself and looped around and tightly embracing said mufiler member, the thus formed strands of said continuous piece be- Specification of Letters Patent.

ing twisted. back one upon the other and adaptedto form a loop-terminal C at its outer end for facility of engagement therewith by the finger. a

The stem formed of the Wire-or wires so bent will lie upon the bottom of the horn or megaphone, with the end loop 0 of said stem extending a few inches beyond the megaphone or horn and thus remain more firmly at the place where it is desirable to use it, for results according to the record being used and the' general surroundings.

.From this structural characteristic of my invention, it will be noted that no additional contriva'nce is necessary to hold the device in position, but, because the outer looped end C of the stem having a tendency to pull outwardly and the inner end A, a tendency to pull inwardly or oppositely, there is an equilibrium manifest, and the device or regu.-

later will not only stay .just Where it is placed, but it will equalize its own weight to such an extent that the reproducer of the machine is not required to carry any harmful weight.

I claim 'A device of the character. described for a megaphone, comprising a sound-muffler member and a stem-member 'arrying' the ing a looped finger engaged terminal at its opposite end, said stem-member being adapted to lie upon the bottomof the megaphone and to inclineinwardly and downwardly toward its inner end and to incline outwardly and downwardly toward its outer end' at about a median line passing vertically through said stem-member, said stem-member being formed of a continuous piece bent about centrally upon itself and looped around and tightly embracing said s011ndmutller member and the thus formed Strands of saidcontinnou's piece being twisted back one upon the other and forming the looped finger engaged member-at its outer end.

Signed by me this eleventhday of January 1908. l
