GEORGESTEIN, OF NEW YORK, N. Y.
ELECTRIC LAMP.
SPECIFICATION forming part of Letters Patent No. 729,906, dated June 2, 1903. Application led August 12,1902. Serial No. 119,420. (No model.)
To @ZZ whom, it may concern:
Be it known that I, GEORGE STEIN, a citizen Of the United States, and a resident of the city of New York, borough Of Manhattan, in the county and State of New York, have invented a new and Improved Electric Lamp, of which the following is a full, clear, and exact description.
This invention relates particularly to improvements in small electric lamps designed for the use of physicians, surgeons, dentists, or the like in making nasal, mouth, and other examinations, the Object being to provide a lamp so constructed that either a continuous or intermittent light may be had.
I will describe an electric lamp embodying my invention and' then point Out the novel features in the appended claims.
.Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi- -cate corresponding parts in all the figures.
Figure l is a perspective view of an electric lamp embodying my invention and showing its battery connections. Figs. 2 and 3 are longitudinal sections showing the parts of the lamp in different positions; and Fig. et is a perspective view showing in full lines the position of parts for intermittent lighting and indicating in dotted lines the position of parts for a continuous light.
The lampcomprises two tubular metal sec-m tions 1 2. In one end of the section l the lamp 3 is arranged, having one pole of its filament in electrical connection with the section.
rIhe other pole of the filament is connected to a pin 4, adapted to be removably inserted in a tube 5, arranged in the tube-section 1, but insulated therefrom at one end by a block 6 of insulating material and at the other end by a block 7, Of insulating material, the end of this block 7 being extended beyond the end of the section 1, so as to be inserted into the end Of the section 2, thereby making use of Of course when not in use the two sections of the lamp may be separated and held in the straps shown onf the casing.' On one of the sections Of the lamp, here shown as the section l, is a spring-plate l5, designed to be pressed into engagement with the section 2 tO close the circuit.
In operation when the adjacent ends of the sections 1 and 2 are slightly separated, as in dicatedjin Fig. 2, the plate 15 when pressed against the section 2 will close the circuit, and of course upon releasing the pressure On said plate the circuit will be opened. Should a con tinuous light be desiredMthat is, a light for several minutesthe two sections 1 and 2 are 'metal sections, a lamp removably placed in Aone of the sections, a -metal tube in the section in which the lamp is arranged, a pin extended from one pole of the lamp-filament into said tube, a pin or rod arranged in the other section and adapted lto removably engage in said tube, and electrical connections with said rod and with the section containing the lamp.
2,. An electric lamp, comprising two tubular sections, a lamp removably supported in one of the sections, a tube in the lamp-supporting section, blocks of insulating material arranged in said section and supporting the tube, one of said blocks being extended beyond the end of the section so as to enter the other section, a pin having connection with the lamp-filament and extended into said tube, a pin supported in the other section and insu lated therefrom and adapted to enter said tube, a battery, wires extended from said battery to connection with the rod and lamp section, and a circuit-closer arranged on One of the sections and adapted to be pressed into engagement with the other section.
In testimony whereof I have signed my name to this spec'iiicationin the" presence of two subscribing witnesses.
