JOSEPH T. BERTHELOTE, OF HAVRE, MONTANA.
BELL-MUFFLER.
Application led September 14. 1918.
To all whom t may concern Be it known that I, JOSEPH T. BERTHF.- Lo'rn, a citizen of the United States, residing at Havre, in the county of Hill and State of Montana, have invented new and useful Improvements in Bell-Mufflers, of which the following is a specification.
This invention has reference to means for muflling the sound of telephone bells.
The primary object of the invention is to produce a device of this character which shall be self-sustaining when arranged upon the bells, the same being provided with cushion elements that directly engage with the bells to muflle or dampen the sound therefrom.
In carrying out my invention it is my purpose to produce a dampening or muflling device for telephonev bells in the nature of a spring frame, comprising an arched member 'having lateral extensions at the ends thereof, each of the latter being provided with linturned ears, and `between these ears are pivotally secured segmen-ts of rubber or other compressible material. The arched central portion of the frame normally forces the ends thereof toward each other. The inner ears are arranged inward of the bells, and the compression or tension exerted by the arched member forces the compressible elements into contact with the bells, and consequently sustains the device in operative position without the employ` ment of auxiliary fastening means.
I accomplish the foregoing objects. and others which will appear as the nature of the invention is better understood, by a construction, combination and operative arrangement of vparts referred to in the following description and set forth in what I claim.
In the drawings:
Figure 1 is a front elevation illustrating the application of the improvement;
Fig. 2 is a sectional view approximately on the line 2 2 of Fig. 1;
Fig. 3 is a sectional view approximately on the line 3 3 of Fig. 1; and
Fig. 4 is a perspective view of the improvement.
The advantages and desirability ofl mufling telephone bells is too well known to be set forth.
A portion of a telephone box is, in the drawings, indicated by the numeral 5, the
Specification of Letters Patent.

seria; No. 254,081.
bells thereon are indicated by the numerals (i, the striker for the bells by the numeral 7 and the arched protector for the striker by the numeral 8.
The improvement is in the nature of a frame, comprising an arched central por tion 9 having widened ends 10 which are bent angularly, in the same direction from the arch 9, providing the lateral ends of. the frame. These ends, outward of the arch 9 have, upon their edges inwardly extending ears 11 and 12 respectively. The inner ears l2 are longer than the outer ears 11, and the pairs of ears are preferably disposed at an outward angle with respect to the arch 9. Pivotally secured between each pair of ears 1l and 12, as at 13 is a segment 14 ofy compressi'ble material, rubber preferred, and the inner concaved surfaces 15 of the compressible elements 14k are so shaped as to cngage with the` periphery of the bells 6.
As stated, the frame is constructed of resilient material, and the arched portion 9 is designed to spring the ends 10 toward each other. The longer ears 12 being arranged inward of the bells will contact with i the edges thereof, and the spring exerted by the arched member 9 will cause the compressihle dampening or muffler members 1-l to tightly engage with the bells, and as a consequence soften the sound thereof and silence the noise caused by the vibration of the striker.
`While the construction is illustrated in connection with two bells, it will be noted that the central arched member of the frame will permit of the same being arranged on a single bell.
It is believed, from the foregoing descrip tion, when taken in connectionl with the drawings that the simplicity of the construction and the advantages of the device will be perfectly apparent. It is to be stated, however, that while I have illustrated a satisfactory embodiment of the improvement as it now appears to me, I may, at a. later date desire to make changes therefrom, and therefore I am not to be restricted to the device as described and shown, but am entitled to all such modifications as fall within the scope of what I' claim.
Having thus described the invention, what is claimed as new, is
1. In a device for the purpose set forth, a resilient frame including an arched centralportion having lateral ends, andcom.
pressible elements pivotally secured Ato said ends.
2. In a device for the purpose set forth, a resilient frame including a central arched portion having lateral ends formed thereon, ang cornpressibleelements carried by said @Il S- 3. In a device for the purpose set forth, a resilient frame including a central arched portion having lateral ends, and pivoted segments of compressi-ble material on said en s.
4. In a device for the purpose set forth,
a resilient frame, including a central arched portion having lateral ends, ears on the edges of said ends to the opposite sides of the arch, and a compressible element pivotally secured between each pair of ears.
5. In a device for the purpose set forth, a resilient frame including a central arched portion having lateral ends arranged at an angle with respect thereto, ears on the edges of said ends to the opposite sides of the arch, the inner ears bein of a greater length than the outer ears, and a segment of compressible material arranged between each pair of ears and pivoted thereto.
In testimony whereof I affix my si nature..
