0. T. LEE. INGANDESGENT LAMP SOCKET.

Patented Aug. 15,1893.

arnnr OFFICE.

"CHARLES TENNANT LEE, OF BOSTON, MASSACHUSETTS.

EMEAMUESCENT- LAMP SOCKET.

SPECIFICATION forming part of Letters Patent No. 503,349, dated August 15, 1893.

Application filed May 3, 1892. Serial No. 431,651. (No model.)

To ail whom it may concern.-

Be it known that 1, CHARLES TENNANT LEE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sockets for Incandescent Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide a durable and efficient water-proof socket for incandescent lamps with which the lamp may be readily connected and from which it may be easily detached, and it consists in a socket provided between its mouth or open end and the terminals with a ring of rubber which projects into the cavity of the socket and is so located as to come in contact and form a tight joint with the glass portion of the lamp, all as hereinafter set forth and as more particularly pointed out in the claims which are appended hereto and made a part hereof.

In the accompanying drawings, I have shown my invention as applied to two forms of socket, both figures of the drawings showing a socket in vertical section with a lamp therein, the lamp being partially broken away.

In Figure l the socket is threaded and the lamp adapted to be screwed therein. In Fig. 2 one of the terminals is provided with spring tongues which when the lamp is thrust into the socket snap over an annular projection thereon and hold the lamp in place.

My invention is simple and will be readily understood from the following description in which reference is made to the accompanying drawings.

A represents the socket, which is integral throughout and made from a composition of matter which may be molded while in a plastic condition into the desired form. The terminals l) c to which are attached the conducting Wires (1 e are molded or embedded in the material of the socket when the socket is formed; the insulating covering. of said ends being also incased within the said material as shown. The open mouth of the socket beshoving it home in the socket the spreading sides of the bulb will be forced tightly against the rubber ring h compressing the ring and preventing the passage of moisture inwardly t0 the terminals. \Vhen the lamp is in position'the rubber ring will stay in place without being secured to the socket but to prevent the rubber ring from becoming dctached from the socket when the lamp is removed the ring may be secured by adhesive material or in any well-known manner to the socket or an annular recess may be formed around the inside of the mouth of the socket for the reception of the ring it as shown at I Fig. 2. By thus sealing the mouth of the socket when the lamp is in position at a point below the metallic terminal 0 all moisture is prevented from coming in contact with any part of said terminal and this is desirable.

\Vhat I claim is- 1. A molded socket for incandescent lamps provided between the mouth thereof and the terminals with a ring of rubber, which pro jects into the cavity of the socket for the purposes and substantially as set forth.

2. A molded socket for incandescent lamps, provided between the mouth thereof and the terminals with a ring of rubber, said ring of rubber being secured in an annular recess in said socket, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES TENNANT LEE.
