T0 ctZZ'w/"wm/ it may concern;
Be it known thatI, J ESSE CASPER MORRIS BROWN, a citizen of the United States, residing atthe city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Incandescent Electric Lamps and Sockets, of which the following is a specification.
My invention has relation to a socket connection for an incandescent electric lamp; and in such connection it relates more particularly to the construction and arrangement of the lamp and thefsocket for receiving the same.
The principal'objectsof my invention are, first, to provide a 'socketi for; an incandescent electric lamp,compr-ising,essentially, an insulating-basefromwhichprojects vertically a series of. fiat sprin'gsjor spring-fingers arrangedyinfthe" form of a tube .to receive and hold the neck of a'lamp under spring tension, one of the vertical fiat springs or fingers forming one terminal for the electric current, and in;conjunction with these vertical spring-fingers the base is provided with a horizontal fiat finger, forming the other terminal of the current and adapted to rest under spring tension upon the under face of the neck of the lamp when the lamp is placed in the socket,
and, second; to provide, in conjunction with such a socket, a lamp having on its neck a metallic sleeve connectedwith one end of the incandescentbo'dy within the lamp and on its base a terminal'jfor the other end of said incandescent body, the metallic sleeve adapted .to contact with the vertical contact springfinger forming part of the socket and the baseterminal adapted to restion the horizontal finger of thejsocket when" the lamp enters said socket.
The nature and scopeof my invention will be more fully understood from the following description, taken in connection with theaccompanying drawings, forming part hereof, in which+ v i Figure 1 is a'front elevational view of a lamp and socket embodying main features of my invention. Fig. 2 is a transverse sectional view, partly in elevation, illustrating the construction and arrangement of the lamp neck and socket. Fig. 3 is a top or plan view of the socket with the lamp removed; and Fig.
4 is a transverse sectional view of the socket taken on the line 4 4 of Fig. 3, but with the neck of the lamp in the socket. Referring to the drawings, a represents th base of the socket, made of insulating material. ject the vertical spring-fingers b, one of which, I), is connected to one terminal 61 of the electric current in any suitable manner. Each spring-finger b and b is arranged independently of the others and is bent outward at its upper end, as at b so as to more readily permit of the'insertion of the neck of the lamp A and to lock the fingers b and 1) against the side of the neck, as hereinafter more fully described; From the base CL of the socket also projects the horizontal fiat finger e, to which theuother terminal d of the current is connected in any suitable manner. This horizontal finger e is yielding or resilient and restsu'nder"spring tension upon the base of the lamp-neck whenthe lamp is in the socket. From the base a also projects the sleeve or collarf, having an inner insulating-face surrounding the vertical spring-fingers b andb' and serving notonly as a protection for the fingers, but also as a finish for the socket. The lamp A has a neck-g, surrounded by a plain metallic sleeve 9', and'on itsbase is provided with a plate, or terminal 9 One end of the filament within, the lamp extends to the sleeve 9 and'the'other end to the plate or terminal 9 as clearly illustrated in Fig. 2. In operation when the neck g of the lamp is slipped into the socket the metallic sleeve g restssubstantially fiat-against the body of the spring-fingers b and b, and especially againstmhe fingerlb", which is one terminal for the electric, current. The bends Z) of the springs 19 and b snap into the neck above the sleeve 9 to prevent accidental withdrawal or displacement of the lamp in the socket. The terminal plate g of thelamp-neckrests upon the fiat horizontal finger e of the "socket, and when wholly within the socket the-base of the neck slightly bends or displaces this horizontal finger e, so that said finger will rest under spring tension upon the terminal plate 9 to form a more intimate contact between the terminal q and the finger e, which finger, as hereinbefore explained, is connected with ,the other terminal of the our- From the upper face of the base a prorent. Should, for instance, grease, dirt, or rust form on either the terminal plate 9* or finger e or upon the sleeve 9 or vertical finger b, a slight turning of the lamp in the socket will remove these obstructions to perfect contacts.
Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, i s
1. An incandescent-electric-lamp socket, comprising a Hat ring-shaped base of insulating material, a series of independent springfingers supported at their base upon and insulated from each other by the upper face of the insulating-base and projecting upward therefrom to form in series a tubular socket to receive the lamp-neck, a terminal for the current connected directly to one of said spring-fingers, a flat spring-finger supported upon the face of the insulating-base and projecting inward parallel to said face and over the opening in said base, and a second terminal for the current connected directly with the flat spring-finger.
2. In an incandescent electric lamp and socket, a socket comprisinga flat ring-shaped insulatingbase, a series of independent spring-fingers supported upon and insulated from each other by said base and projecting upward therefrom to form in series a tubular socket, a terminal for the current secured directly to one of said fingers, a flat springfinger supported upon the insulating-base and projecting inward over the opening in said base, a second terminal connected with said flat spring-finger, asolid collar or sleeve supported upon the insulating-base and pro-- jecting upward therefrom, said collar or sleeve surrounding the vertical fingers and having an inner insulating-face adjacent to said fingers, in combination with a lamp having a neck and an inclosed incandescent body, a plain metallic sleeve surrounding the neck and connected directly with one end of the incandescent body, said neck and sleeve adapted to enter the vertical fingers of the socket, and a terminal plate formed on the base of the lamp-neck and adapted to enter the opening in the ring-shaped insulatingbase of the socket to contact with the flat finger of said socket. In testimony whereof I have hereunto se my signature in the presence of two subscribing witnesses.
