ELECTRIC LAMP;

Applieation flled April 9,

To all whom it, may concern:

Be it known that I, JOHN P. NIKONOW, a citizen of Russia, and a resident of the city, county, and State of New York, have invented a new and useful Improvement 1n Electric Lamps, of which the following is a specification.

My invention relates to the electric lamps, used generally on-the automobiles, motorboats, etc., which are commonly known as spotlights, and has a particular reference to such lamps, which can be removed with the reflector from the housing and with the help of extension conductors used as trouble or portable lamps.

My invention is explained more fully on 1 fastened inside of the housm 4. Screws 5 serve to fasten the ring and ream together. A metal tube 7 is inserted into the opening in the rear end of the reflector and is fastened in its place. The in-' side end of the tube receives a lamp 8, and

to the other end of this-tube is fastened a disk or plate 9. The tube 7 forms a support for the flexible conductors II, which can be wound on this tube, as shown. One end of the conductors is connected to the lamp leads 10, and the other extends through the bushing 12 in the housing 13 and is connected to the source of the electric current.

The front end of the housing I has a screw or pin 14, which fits into a two way groove or slot 15 in the cylindrical extension of the rim 3. This construction allows the reflector with the lamp to be removedfrom the housing and used as a portable lamp, whenever desired, or inserted in the housing and used as a Searchlight. The screw 14 may be tightened by hand to prevent the lamp from jarring loose. Felt or rubber packing 24 may be cemented to the inside surface of the rim and form a watertight joint.

A mirror 16 may be fastened to the rear Specification of Letters Patent. 1

nected to the rod 18. This rod is clamped between two plates 20 by means of screw 21. Screw 23 serves to draw together extension 22, with which the whole bracket is fastened to some part of a vehicle.

Springs 25 may be fastened to the rear of the housing. These springs enter the rear end of the tube 7 under some tension, than keeping the whole portable element (consisting of a reflector, lamp, supportin extension and a flexible cord) tlght an secure from .vibration.

Fig. 2 shows a different method of bringing conductors through the housing. Here instead of a bushing 12, a connector 26 is employed, to which the ends of lead II are A flexible lead 27 with the connector 28 1s used in this case to establish connection with the source of a housing provi ed with a front opening;

a portable unit normally housed within said casing and removable therefrom through said opening, said unit comprising a lightsource, a reflector associated therewith, a tube supported by and extending rearwardly from said reflector and supporting said light-source, a disk carried by and adjacent to the rear end of said tube; and light-source supply conducting means extending from said light-source within said tube and laterally therethrough forward of said disk 4 and through said casing to the exterior of the latter, said conducting means being norll allgy wound on said tube forward of said is In testimony whereof I have hereunto subscribed my name this 27th day of February,
