TELEPHONE HEAD SET.

Application filed August 5, 1924. Serial No. 730,158.

This invention relates to headsets such as are used by telephone operators.

The object of my invention is to provide a headband that is not only simply and economically constructed, but one that is adjustable, durable and sanitary.

The invention consists in a single wire headband shaped to fit the head and automatically adjustable to either ear, having a receiver clip at one end and a metal headpad at the other end which is ventilated for comfort and designed to minimize haircatching. The device is constructed entirely of metal and is, therefore, easily kept clean and sanitary. More specifically, the invention consists of a headband having a self-adjustable receiver engaging means, consisting of a spacing strip having its opposite ends embracing the wires and provided with slots with which bends in the wires cooperate to permit a limited transverse movement of the receiver, and an all-metal headpad at the other end of the headband;

Referring to the drawing in which like characters designate like parts in the several views Figure 1 is a. front View of a preferred form of my invention;

Figure 2 is a view partly in section showing the receiver strip arrangement;

Fig. 3 is a transverse sectional view of the receiver strip arrangement in Fig. 2, showing an angular transverse movement which may be obtained.

Figure 4; is a front View of the head-pad.

Figure 5 shows a transverse section of the head-pad along the line 55 of Figure 4; and

Figure 6 shows a modification of the headpad to be slidab-ly adjustable.

The band 1 consists of a flexible springy wire, preferably tinned piano Wire, bent back on itself to form a U, and shaped to fit the head as shown in Figure 1. The tips 2 of the wire are bent to an angle of 90 to fit into the recesses in the side of the receiver case 3, and are spaced by a spacing member 4 which is preferably of German ornickel silver and consists of a strip, the ends of which are crimped around the two strands of the wire band. An aperture or slot 5 is provided in each side of the strip at to receive the projecting V-shaped bends 6 in the wire 1 so as to give a limited angular transverse movement in the strip 1 to an extent of approximately 10 on each side, as indicated in Figure 3. Thus the receiver automatically adjusts itself to the angle which the ear makes with the side of the head and consequently with the plane of the headband.

The head-pad may be made either rigid as shown by 7 in Figure 4 or adjustable as shown by 8 in Figure 6. It is made of a strip of nickel or German silver crimped around the wire 1 and perforated with a series of holes 9 for ventilation. In the case of the rigid hcad-pad 7, the edges of the metal are crimped around the wire so as to make the pad immovable, whereas in the adjustable type 8 the pad is slidably movable to any position relative to the head because the four bearing loops 10, 11, 12 and 13 are loosely crimped around the wire 1 to be a sliding fit thereon. The smooth and fiat surface of the head-pad is turned inwardly and rests against the head, and, being of a design which is free of projections or depressions, it reduces the possibility of hair-catching to a minimum.

While this specification and the accom- )anying drawings illustrate the invention, it is understood that variations in the design and structure may be made without departing from the spirit or scope of the invention defined by the appended claims.

What is claimed is 1. A headband comprising a flexible member formed to fit the head and having two cooperating opposed tension members, a receiver mounted between the ends of said tension members, a spacing strip having its opposite ends engaging said opposed members near their ends and being provided with slots with which bends in the said tension members cooperate for permitting the automatic adjustment of the receiver.

2. A telephone headband comprising a single resilient wire bent to form two parallelly disposed arcuated portions, a pad fitted at one end of the arcuated portions, a pivot member extending at right angles from each of said portions adapted to fit holes in the receiver, and'a strip adjacent the receiver loosely connecting said wires for holding said pivots in said holes, and means in said strip for permitting'the adjustment of the receiver with respect to the plane surface of said pad automatically.

3. A telephone headband comprising a single flexible Wire bent to fit the head, a receiver, aspacing strip the ends of said Wire shaped to engage said receiver and spaced by said strip, said strip permitting a liinitedangular inoveinent of said receiver, and a metal head-pad disposed opposite said strip at the other extremity of said band.

&. A headpiece for telephones comprising a single Wire headband, a spacing strip at one end ,of said band, said strip being formed of a single piece of metal the ends ceiver, and a perforated head-pad formed of a strip of metal mounted on the other end of said band.

In Witness whereof, I hereunto subscribe my naine this 28th'd'ay of July A. D., 1924.
