UNITED STATES PATENT OFFICE.
WILLIAM R. MILLER, OF BALTIMORE, MARYLAND.
TELEPHONE.
SPECIFICATION forming part of Letters Patent No. 312,492, dated February 17, 1885.
Appicaton tiled June 1G, 1984. (Xo model.)
To all whom it may concern:
Be itknown that I, WILLIAM R. MILLER, of the city of' Baltimore, and State of' Maryland, have invented Cert 1in Improvements in Telephones, of whichthe following is a specification.
rI`his invention relates to certain improvements in t-he receiving-instrument of a telephone, and specicallyto that class of' receivers in which a sound-insulating cup adapted to fit over the ear is used.
The said invention consists in the combi nation, with a telepl'ione-receiver having the usual diaphragm cover or concaveplate, which is adapted to tit against the ear of' the person receiving the message, of a flexible sound-insulating cup which surrounds the said plate, but is independent thereof' and :It zpted to iit over the ear and to yield as pressure is applied to the telephone to allow of the contact ofthe ear with the said curved plate;
It further consists in. providing the flexible elastic cup with a rigid edge composed of hard rubber or some similar material, which may be easily cleansed, and which will not become sticky or sot't when handled or subjected to the action of the natural grease of the skin or that of the hair cf the head with which it must necessarily come in contact in its constant use.
In the drawings forming a part hereof, Fig ure I is an exterior side view of the receivinginstrument of a telephone provided with my invention,which is shown as partly sectional.
Fig. II is a similar view illustrating a modi l fication in the construction of the invention.
A is the telephone-receiver, having the usual curved plate, c, to cover the diaphragm, and to be brought against the ear when the instrument is in use. B is the sound-insulating cup, formed of rubber or some other elastic and iiexible material, having a rigid edge, b.
In Fig. I the rigid edge is merely a circular bead. in which the edge of the cup is inserted, and the cup is secured around the end of' the telephone and entirely clear of' the curved plate.
In Fig. Il the cup is unprovided with the bead b, and the cup brought below the enlarged end of the telephone, where it is fastened to the body thereof.
It will be understood that in both cases the telephone is provided with a fiexible soundinsulating cup -iudependent ot' the curved plate c, which may be compressed in its ap` plication to the head to admit of' the ear coming in contact with the said plate.
In this invention the adj ust-ment of the outer edge ofthe cup beyond the receiver is automatically accomplished in the act of' bri nging the ear in contact with the curved plate covering the diaphragm.
I claim as my inventionl. In combination with a telephone receiver having the usual curved plate to cover the diaphragm and adapted to be brought inv contact with the ear, a flexible sound-instilating cup attached to the said receiver of' greater diameterthan the said plate, and with its edge projecting beyond the end of the said receiver, substantially as and for the purpose specitled.
2. In combination with a telephone-receiver having the usual curved plate to cover the dia ph ragni and adapted to be brought in contact with the ear, a tlexible sound-insulating cup attached to the said receiver of' greater diameter than the said plate, having a rigid edge which projects beyond the end of the said curved plate, substantially as and for the purpose specified.
\VM. MILLER.
