EDWIN CHARLES HESS, OF. CAMDEN, NEW JERSEY.
TELEPHONE-RECEIVER.
srncrrrcnrron forming pm of Letters Patent No. 473,256, dated April 19, 1892.
Application filed July 1, 189i.
To all whom, it may concern: v Be it known that I, EDWIN CHARLES HEss,
a citizen of the United States, and a resident of Camden, Camden county, New Jersey, ha e 1 invented certain Improvements in Teleph i8- Receivers, of which the following is a sp't oi fication.
The object of my invention is to so construct a telephone-receiver that it can be applied to both ears of the person using the receiverat one and the same time and to seconstruct the receiver that the ear-pieces will fittightly to the ears, my improvements being readily attachable to the ordinary Bell re ceiver.
In the accompanying drawings, Figure 1 is a side View, partly'in section, of my improved telephone-receiver. Fig. 2 is an enlarged face -'view, looking in the direction of the arrow,
Fig. 1. Fig.3 is a-section on the line 1 2, Fig. 2. Fig. 4 is a perspective view of the yokes of the connecting-arm. Fig. 5 is a modification of the universal joint. Figs. 6 and 7 are views of modifications of the joint between the primary receiver and the connecting-arm, and Fig. 8 is a view of a modification.
I A is the receiver'of an ordinary Bell telephone-instrument having the usual bindingscrews a a. The usual ear-piece has been removed and my improved ear-piece B substituted therefor. In the present instance this ear-piece is screwed upon the instrument and holds the diaphragm a, inplace; but it willbe understood that the ear-piece can be attached to the instrument in any suitable manner, and,in fact, in some instances may be applied directly to the ear-piece of the instrument where circumstances prevent the removal of the original ear-piece. The ear-piece B has a central projectionb, which is adapted to enter the ear, and in this projection is the opening 0. Around the earpiece is a cushion 0, made in the present instance of a thin rubber tube, which will yield and accommodate itself to the ear, so. that when a person is receiving a message the ear is shut off entirely from outside noises.
Pivoted to the ear-piece B is an arm D. This arm-D, as shown. ill-"Fig. 1, is yoked and pivoted at dd on each side of the receiver. The arm is sprung in place in the present instance; but screws or pins may be used as Serial No. 398,111. (No model.)
pivots when necessary. The arm D is so bent as to pass over or back of the head of the person using the instrument and has at its opposite end a receiver E, provided with an earpiece F, similar in form to the ear-piece B, having the cushion 0 and a projecting portion b. The receiver is connected to the arm by a universal joint 'e, and, as shown inFig. 1, this joint is made of a flexible tube, preferablyxof rubber, secured to the end of the arm and to a projection on' the receiver; but the joint may be made as shown in Fig. 5, which illus: trates a ball-and-socket joint.
The receiver E is provided with a diafor the transmission of speech. 7
The arm D and ts yoke-section are hollow, and in this hollow arm are the wires a: x, which make a circuit including the receiver E, the wires passing to the binding-posts c on the receiver E,:and their opposite ends pass out orifices g g and along each side of the receiver A to their binding-posts 0, as clearly ranged that both circuit. v v
The tubular arm D may connect with the space inffront of the diaphragm of the receiver A through-hollow pivots, as shown by dotted lines in Fig. 2, and'also may connect with the space in front of the diaphragm f, Fig. 1.
receivers are in the same the wires from the arm, as clearly shown in said figures. i
which the magnetic portion of the receiver E is removed and connection is made between the space and front of the diaphragm of the receiver A through the medium of a hollow tube b, the Wires a: w in this case being dispensed with. It will thus be seen that when my instrument is used both ears are sealed phragm f and internal mechanism necessary shown in Figs. 1 and 2, the wires being so ar Thus in the event of themagnetic, "portion of the receiver E not working satis-' the bearing being hollow for the passage-of In Fig.8 I have shown a modification in against outside noises, the projections 11 Z2 entering the ear and the cushions C fitting snugly against the outer portions of the ear.
The arm D, carrying the receiver E, can be thrown back over the head and the instrument readily removed.
The universal joint between the arm D and receiver E allows the instrument to accommodate itself to the headof the user.
I have made the instrument so that it can be applied to the receivers now in common use; but a receiver embodying my invention may be made in which a special construction or arrangement of the portion A may be advisable.
It will be understood that the cushion C may be made of other material than rubber and may be made diiferent shape in cross section. v
I claim as my invention 1. The combination,in atelephone-receiver, of the main standard receiver, to which the main wires are attached, an arm pivoted to said main receiver, and a second receiver carried at the opposite end of said arm, with wires passing through the arm from the main wires and attached to the opposite receiver, so that both instruments will be in circuit without.
disturbing the general arrangement of the standard receiver, substantially as described. 2. The combination of the standard receiver as a main receiver, the ear-piece B, secured thereto, a hollow arm D, pivoted to the earpiece B, with a receiver E, a universal joint connecting the receiver E with the hollow arm, and an ear-piece F on the receiver E, with wires or: m passing from the standard receiver rimthrough the arm D to the receiver E, substantially as described.
3. The combination of the main receiver A with an ear-piece B,having a central projection b, adapted to enter the ear, a passage in said projection communicating with the space 'in front'of the diaphragmof the main receiver, a hollow arm D, pivoted to said earpiece and communicating with a space in front of the diaphragm of the receiver A, with a receiver E, and a hollow projection b thereon adapted to the ear, said receiver being connected to the tubular arm D, thus forming communication between the two receivers, substantially as described.
4. The combination of the receiver A, the yoked hollow arm D, an ear-piece B, to which the yoke is pivoted, a receiver E, having an ear-piece F, and wires :1: :0, extending along the receiver A into openings 9 g at the rear of the yoke-sections of the arm and passing through the arm arranged substantially as described.
5. The combination of the receiver, the earpiece B, the central projection b,with passage therein communicating with the space in front of the diaphragm of the receiver, and a hollow annular cushion O, secured to the earpiece and extending beyond the central projection b, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two' subscribing witnesses.
EDWIN CHARLES IIESS.
