ATTACHMENT FOR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 366,994, dated July 19, 1887.

Application filed April 16, 1887. Serial No. 234,997. (No model.)

To all whom it may concern.-

Beit known that I, THOMAS C. BRADFORD, of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Attachments for Telephones, of which the following is a specification.

The several features of my invention and the advantages arising from their use conjointly or otherwise will be apparent from the following description.

In the accompanyingdrawings, forming part of this specification, Figure 1 is a central section of my device. Fig. 2 shows in elevation my device attached to a telephone. Fig. 8 is a central section of thedevice as shown in Fig. 2. Fig. 4 is an elevation showing the device attached to a telephone and telcscoped down, as set forth in the specification. Fig. 5 is a central section of the device as shown in Fig. 4.

The attachment is made of a single piece of elastic material, preferably of rubber. When detached from the telephone, the attachment is seen to consist of a contracted portion or curtain, A, preferably cylindrical, or nearly so,

in shape, and a flaring portion, B. At the junctions of the portionsA and B the material is thickened by the presence of'a bead or ring,

C, on the inside. The free edge of the flaring portion B is stiffened by a cushion'ring, 1), preferably rather broad. The web connecting the bead C and .ring D is designated by the letter b. A bead, E, may also be used to strengthen the free edge of the curtain A, but is not essential.

In applying the device to a telephone the cylindricalportion is stretched over the head I F of the telephone, as shown in Figs. 2 and 3.

tachment securely in position.

The bead C rests on the top of the head F, forming a contraction at the base of the portion B, while the free edge of the curtain A contracts under the head F and holds the at- The web 1) takes a decided concave shape, as shown in Fig.2. In use the ring D completely surrounds the ear and fits snugly against the head, any

inequalities being accommodated by the flexible web Z. When sufficient pressure is made against the ring D, it is forced down and outside of the bead C, while the web I) folds up between the two beads. In this folding the web 1) forms a continuous smooth fold,-which does not at all interfere with the proper functions of the device.

The flexibility of the web b permits the ring D to fit snugly to the head, whether the tele phone be applied directly in front of the ear or slightly to one side. With the telephone to the ear, movements of the head may be made without affecting the snug fitting of the ring D, because of the flexibility of the web I).

1 do not claim, broadly, to be the inventor of an ear-piece for telephones having aflaring portion, a web adapted to fit over the head of a telephone, and a bead or shoulder, as at C, against which the head of the telephone may be made to bear, but limit myself to the inventions set forth in the claims hereof.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In an ear attachment for telephones, in combination with a curtain, the flaring por tion B, provided with cushion-ring D, and stiffening-beads C, with intermediate flexible web, I), substantially as and for the purposes specified.

2. The combination of curtain A,fiaring pou tion B, provided with cushion ring or bead D and web b, and bead C at junction of portion B and curtain A, substantially as and for the purposes set forth.

3. The combination of curtain A, provided with head E, flaring portion B, provided with cushion ring or bead D and web I), and bead C at junction of portion B and curtain A, substantially as and for the purposes specified.
