ADOLF J. MARSCIIALL, OF LITTLEFALLS, NEW, YORK.

ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 699,202, dated May 6, 1902. Application filed March 8,1901. Serial No. 50,324. (No modeLl To all whom it may concern:

Be it known that I, ADOLF J. ll/IARSCHALL, a subject of the King of Denmark, and aresident of Littlefalls, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Electric Gas-Lighters, of which the following is a specification.

This invention relates to that class of portable electric gas-lighters which comprise a dry battery or element arranged in the handle of the implement, a tubular stem which extends upwardly from the handle and contains in its perforated end a platinum coil which has one of its terminals connected with the base of this stem and the other with an insulated wire which extends through the stem to the other pole of the battery, and a device for closing the circuit through the platinum coil at will.

The object of my invention is to produce a gas-lighter of this general character which is simple in construction and convenient in operation and which permits of the ready and convenient renewal of the battery.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved gaslighter. Fig. 2 is an elevation of the lower portion of the same at right angles to Fig. 1.

Fig. 3 is a horizontal section in line 3 3, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A represents the casing of the handle, constructed of tin or other suitable metal and having the form of a long cylindrical can or cup which is closed at the bottom and has at its open upper end a screw-thread a.

B represents the zinc pole of the battery or element which is arranged within the casing and insulated therefrom. This pole is somewhat smaller in diameter than the surrounding casing, and the intervening space is filled with wax, pitch, or other suitable nonconducting material b.

is a. circuit-closing spring or arm which 18 secured at its lower end to the casing A, on the inner side thereof,and which projects with its head 0 or upper end outwardly through an opening 0' inthe casing. This head has the form of a thumb-piece or push-button and enables the spring or arm to be pressed inwardly against the zinc pole for closing the circuit.

D is the carbon pole, which has the form of a'rod arranged centrally in the zinc pole in the'usual way.

E is the packing, arranged between the two poles and consisting, usually, of powdered carbon and manganese peroxid dampened with a solution of sal ammonia.

e is the usual lining of filter-paper, arranged against the inner side of the zinc pole. The battery is sealed with pitch or wax, as usual.-

The carbon pole D is provided above the packing with a semi elliptical contactspring F.

G represents a screw-cap which is applied to the upper threaded end of the casing A and which carries the tubular stem II and the insulated wire I. The latter projects with its lower end through an insulating-plugt'in the lower end of the tubular stem and makes contact with the spring F when the cap G is screwed upon the handle. It is obvious that the arrangement may be reversed and the contact-spring be secured to the wire and make contact with the carbon pole.

represents the platinum coil, arranged in the upper end of the tubular stem and having one of its terminals connected with the insulated wire I and the other with the screw cap G in any suitable manner -for instance, as shown, by a connection'lt", running to the tubular stem, or, if preferred, by a wire running to the cap G. The stem is provided opposite the coil with openings Z, through which the gas finds access to the coil;

m is a hook formed on the tubular stem, near the upper end thereof, for hanging up the implement.

In the use of the implement the push-button c of the springG can be conveniently operated by the hand holding the handle of the implement. When the battery is exhausted, it is unscrewed with its casing from the cap G and replaced by a new casing and battery, which can be furnished at comparatively small cost.

I claim as my invention 1. In an electric gas-lighter, the combina tion of aconducting-battery casing, a battery having an internal and an external pole 10- cated in and insulated from said casing, a lighting-coil, a conducting-support for the same With which one terminal of said coil is electrically connected, means for detachably and electrically connecting the coil-support with the casing, a conductor connecting with the other terminal of the coil and detachable with said coil-support from said casing, a contact for connecting said conductor with said internal pole of the battery, and a hand-controlled means for making electrical connection between said casing and said external pole of the battery, substantially as set forth.

2. In an electric gas-lighter, the combination with a lighting-coil, a supporting screw cap and tubular stem, an insulated Wire arranged Within said stem, and a lighting-coil having one terminal connected with said cap ADOLF J. MARSOIIALL.
