BYRON Q. JONES, OF WASHINGTON, DISTRICT OF COLUMBIA.
DIAPHRAGM MUFFLER.
Application filed July 12, 1924.
This invention relates to telephone receivers, the broad object in view being to produce a muftler for the diaphragm of a telephone receiver which can niufi'le the unpleasant cracks due to static and similar causes and which will also mutlie the metallic ringing of the diaphragm without inter-fer ing with the audibility of the signals which it is desired to receive.
Another object of the invention is to produce a telephone receiver mufiier of simple construction which may be quickly applied in position whenever desired. lVith the above and other objects in view, the invention consists in the novel construction, combination and arrangement herein more fully described in the attached specification, and in the claims.
In the accompanying drawings:
Fig l is a side elevation of a portion of a telephone receiver showing the nnifller installed in position, and
Fig. 2 is an end elevation of Fig. 1.
Referring to the figures more particularly by reference numerals, a telephone receiver 1 is provided with a diaphragm 2 against which is held a pad of suitable soft material Serial No. 725,522.
such as felt, by means of a wire or spring which is bent so that the pad is held resiliently against the diaphragm. The spring 4 is so designed that it will easily grip over the telephone receiver in the manner indicated so as to hold itself in position. As shown, the spring extends from the center of the receiver radially outward and is the bent substantially at right angles so as to extend along the back of the flange of the end of the receiver.
I clain1:-
1. A device for muiiling the diaphragm oi" a telephone receiver comprising a muffiing pad and a spring clip formed to engage the exterior of the receiver and adapted to resiliently hold said pad against said diaphragm.
2. In a device for mui'liing the diaphragm or" a telephone receiver. a spring wirebent to fit about the edge of said receiver, a mafiiing pad securet to the inner end oi said wire and adapted to be resiliently held against said diaphragm for the purpose described.
In testin'iony whereof I afiix my signature.
