(Cl. 173-328)- This invention relates to sockets for electric a projection I to be engaged above the rib formed lamps and has special reference to a socket by said sunken groove'l. The socket body I has whereby the base of an incandescent lamp or bulb a hole 8 at the top to receive the leg of a clip; and may be resiliently gripped when inserted therein. lead wires 9 and it are led in from the converg- 5 The primary object of the invention is to ing perforations at'both upper sides of the socket 5 provide a novel form of socket wherein a resilient body I. They are then connected with a central contactmember is secured with a socket body of terminal H and the metal shell 2 respectively. elastic material such as rubber, the body aiding According to the present invention, the metal in forcing the contact member into engagement shell 2 enlarged at the upper and lower end por- 10 with the lamp base and the contact member and tions and narrow at the central portion is inserted l0 lamp base being provided with interlocking elein the recess 3 of the socket body I in such a manments cooperating to prevent accidental detachner that said upper and lower end portions enment of the lamp from the'socketl gage tightly in the socket body, while the central Another object is to enable an electric bulb portion is left free. Therefore, it is not only pos- UNITE-D STATES' PATENT OFFICE body without damaging the connection of the electric bulb, inserted in the shell of the socket, bulb and its metal base. p with suitable strength by giving suitable elasticity Another object is to secure a metal shell tightly to said narrow portion, but also the connection of to the socket body without the helps: a binding the shell 2 of the socket with the electric bulb 5 20 agent and not merely to enable any damage done is secured by the engagement of the projecting lug to said metal shell of the socket to be repaired 1 of the base 8 above the rib iormedby the sunken simply by drawing it out, but also to prevent the groove 4. 'Moreover, the construction possesses contact of the bared ends of the lead wires by the advantage that the bulb may be attached to means or a flexible partition. p or detached from the socket without any incon- 25 Referring to the accompanying drawing which venience, because of the space formed between the 25 shows an embodiment of the present invention socket body I and the shell of the socket by curvas examples. ing the central portion of the latter inwardly.
Fig. 1 is a longitudinal diametric section view It is to be noted that, in the form herein disof the socket for a small electric bulb according closed, the body is provided withasmoothly cylin- Fig. 2 is a front elevation of a small electric lug open at the said lower end, and that the shell bulb for use in the socket of thisinvention: is held in this'body solely by, the elasticity of the Fig. 3 is the position in which the small bulb body which grips tightly on the shell. This obshown in Fig. 2 is fitted to the socket shown in 'viates the necessity of molding screw threads in the body or oi providing other means than the InFigs. l to 3, l is a socket body of elastic natural body-elasticity-to retain theshell in place.
