TELEPHONE-RECEIVER. y

Sp ecication 'of Letters ,Patent Patented Feb. 2, 1909.

Application led December 24, 1907. Serial N o. 407,910.

To all whom 'it may concern: V Be it known that I, TILLIAM E. PETERS, a citizen oi the United States,'residing at Athens, inthe county of Athens and State of Ohio, have invented certain new and useful Improvements in Telephone-Receivers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to vwhich it appertains lto make and use the same.

This invention relates to new and useful vimprovements in telephone receivers.

The principal object of the invention is the production of a simple and economical 'receiver cap, through the use of which they.

ressure exerted upon the ear will be transf l'erred to the head, so that bruising of the ear and the vattendant annoyances resulting therefrom may be obviated.

' is a view illustrating the application of 'the outside noises. v

invention to a head band receiver 'of any common ty e. Fig. -2 is a central cross sectional view o the invention o n an enlarged. scale.

Referring to thedrawings, which are for illustrative purposes only, and, therefore, not drawn to scale, thenuineral i indicates the body of the-receiver, and 2 the im roved cap, whichl is designed to be attache to, orI

to take the lplace of the various formsof caps now in use, and which constitutes the invention. This cap comprises an annular body 3 of hard'rubber or other suitable material, which is of suflicient size to inclose the ear of the operator, or user.

In carrying out the invention, a dia hragm or support 4 formed with a relative y large centra opening 5 is arranged in the annular body 3v of the ca at the desired distance from the inner e ge thereof, and a corre- Spending cushioning ring 6, of soft rubber,4

felt, heavy cloth or like material arranged over the inner face of the diaphragm, said ring servingasa bed for the inner end of. the receiver body and is a means fon excluding The dia hragm '4 is spaced lfrom one edge of the cap o'dyS to provide the latter with a rim or ange 7 whichis interiorly threaded to screw upon one end of the receiverbody. A cushioning ring 8 of soft rubber, felt or other like material is also arranged in the cap body 3 with its outer ed eproiecting slightly be-4 yond said edge of t "e atter in.ord er to bear against the side of the head and face to protect the samefrom'becoming bruised or 1rri tated'and thev attendant annoyances resulting therefrom. Said cushioning ring 8, which is of straight form in cross section, is retained in position by a clamping band 9 of hard rubber or thelike, formed at its inner edge with an annular outstanding iange 10 which its against the inner surface of the cap body to retain the clamping band in detachable position.

If found'desirable, instead of relying on the pressure exerted upon opposite faces of the ring 8 for securing it in position, it maybe fastened in any suitable manner to the-fas. tening .ring or band-9.

From the construction `defined and illus,-A trated, it will be seen that a cap constructed in'accordance with the invention may be readily and easily applied orremoved from the body ofthe receiver, and by its use liability of the ear of the operator, or user, be-

coming bruised or irritated,A and the attend-I ant annoyances resulting therefrom will be guarded. against.

Ithas also been found that by employing a cap 'of the construclarge central opening arranged ,within the bod member, said diaphragm bein spaced la slight distance from one edge oft e body member, a cushioning ring corresponding 'with and larranged .over the diaphragm, a

second cushioning -ring of soft exible Inaterial .arranged at the edge of the body member op osite the diaphragm, the outer edge of saidp ring projecting beyond said edge of said ring in ositioii.`
