0. B. ELLIOTT. INGANDESGENT LAMP SOCKET.
Patented Nov. 29, 1892 WI THEEIEEEI UNITED STATES PATENT OFFICE.
CHARLES B. ELLIOTT, 'OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE REVERE RUBBER COMPANY, OF SAME PLACE.
lNCANDESCENT-LAMP SOCKET.
SPECIFICATION forming part of Letters Patent No. 487,213, dated November 29, 1892. Application filed August 8, 1892- Serial No. 442,430. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES E. ELLIOTT, of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in Electric-Lamp Sockets, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention is an improvement in electric head-lights and other lamps; and it consists in a rigid base or support for the lamp, having the lamp-contacts molded permanently therein in a given plane and the coupling-contacts rigidly held in a plane at right angles thereto, the Wires extending in a curve or bend from one to the other through the hollow interior.
In the drawings, Figure 1 represents in vertical section part of a locomotive head-light constructed according to myinvention. Fig. 2 represents enlarged detail of the device.
A represents the base or body of the lampsocket, upon which the bulb B is mounted, the base being formed of hard rubber or the like and having a projecting foot or flange C, perforated to receive the fastening-screws which fix it in position. This base or body has a fiat bottom to fit upon a horizontal or vertical surface to which it may be secured. I
The axis of the bulb is perpendicular to this fiat bottom and the bulb is affixed by a screw action, while the coupling for the conductingwires has a sliding movement'in a plane parallel with the bottom and at a right angle to the bulb-axis. The contacts for the lampsocket are molded permanently in the rigid body A while the material is in the plastic state, so that when it is cured or hardened the parts are held in proper position without further treatment. The pole E occupies a central position, projects above the hard-rubber body, and is screw-threaded for the bulb to screw onto, while the pole F is of annular form, surrounding pole E, with its upper surface slightly above that of the body A, in which both poles are embedded, being roughened or otherwise shaped for the insulating material to take hold of. The insulated wires G H run in a bend or curve from these poles or contacts through a hollow interior of the body to the respective coupling-contacts I J, which are fixed in position at the end of the body A in a plane at right angles to the axis of the bulb B and pole E. These contacts I J are embedded in the insulating-body A and may be molded therein, but are preferably forced into parallel apertures while the ma terial is warmed and expanded, and are thus held rigidly at normal temperatures. The contact I is shown as a slotted tube or socket, and the contact J as a protruding plug, while in the tail-piece M the complemental parts show the reverse construction, the protruding plug K sliding into the socket I and the socket L of the tail-piece receiving the. plug J. The sliding of these parts into and upon each other gives a reliable electrical connection at this coupling. The tail-piece M is cylindrical at the contact end and fits snugly within a projecting flange N, formed on the end of the body A, so that water and dust are excluded at this point. The conducting-wires O extend from the tail-piece to the battery or source of electrical energy.
Around the base of the bulb B, I erect an an nular guard P, screw-threaded in its lower portion to screw upon a threaded part of the body A, surrounding the poles E F. This guard serves to support the lamp laterally against jar or vibration, and is hence of much utility in head-lights and other railway 0r vehicle lamps.
I claim as my invention- An electric-lamp socket having the rigid body A and the contact-poles E F molded permanently therein and provided with the coupling-contacts I J, rigidly held at one end of the body A in a plane at right angles to that of the pole E, said contacts E F and I J being connected within said body by the wires G, substantially as set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 1st day of March, A. D. 1892.
CHARLES E. ELLIOTT.
