HOLDER FOR TELEPHONE-RECEIVERS.

SPECIFICATION forrring part of Letters Patent No. 299,288, dated May 27, 1884.

Application filed October 15, 1883. (No model.)

T0 all whom t may concern,.-

Be it known that I, JOHN N. STEWART, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Holders for Telephonie Receivers, of which the following is a specification.

These improvements relate to the receiving end of telephonie instruments, and consist in the arrangement of two receivers to be applied to each ear of the operator, or a double receiver, whereby the sounds may be heard by both ears at the saine time, the object lo Ting to provide a means ofengaging both ea] s for hearing the sounds, so that the hearer may not be annoyed by the confusion of sounds which are made by outside iniiuences, enabling the hearer to hear the telephonie sounds more distinctly, and at the same time have both hands free for other uses. Heretofore onehand has been required for holding the receiver to the ear, confining the hand to that use, and also leaving the other ear open and free to hear other sounds, which confuse and render the telephonie sounds unintelligible. These objections my improvements entirely overcome. I accomplish these desirable results by arranging two eanpieces on a frame or tongs provided with a suitable spring for holding the receivers to the ears oi' the operator, said receivers being each connected by the wire, so that each simultaneously receive the telephonie sounds, the construction and arrangement being substantially as hereinafter described and claimed.

In the accompanying drawing, the gure shows two levers hinged together near their lower ends and provided with an adjusting spring and screw for regulating the tension of the spring, said levers having attached on their upper ends a telephonic sound-receiving earpiece.

A B represent two arms of a pair of tongs,

bent into convenient `form to adapt them for the use designed. Below the joint said levers extend a short distance, and have interposed between the ends -a spring, C, through which a rod, D, passes, having a head on one end, and the other provided with a screw-thread and a thumb-nut with which said spring may be more or less compressed for regulating its tension. On the ends of the long levers are attached telephonicreceivers E F with their openings toward each other, and the said receivers are connected by the wire, so as to put both in the electric circuit, whereby both receivers work in concert.

The manner of using my device is to take hold of the levers by each hand and spring them apart sufciently, placing the receivers against each ear, letting the bow hang beneath the chin. The tension of the spring compressing the levers will hold the device in place without further use of the hands for that purpose.

The manner of constructing the holder may be variedY from that shown, and any other substantially the same be adopted. A springbow without joint may be employed, if desired; but the jointed levers are preferable, for the reason that the tension of the spring can be adjusted to tit more conveniently various sized heads.

Having described my invention, I claim- In double telephonie receivers, two levers, A B, crossed and pivoted together and provided with spring O and adj usting-screw rod- JOHN N. sTEWART.
