IMPROVEMENT IN ELECTRO-MAGNETIC GAS-LIGHTING APPARATUS.`

Specification forming part of Leiters Patent No. 116,05,da.ted June '20, 1871.

To all whom t may concern:

Be it known that we, FRIEDRICH HEYL and PHILIPP DIEHL, of East New York, in the county of Kings and State oi' New York, have invented a new and Improved Electrical Igniting Apparatus 5 and we do hereby declare that the following is a full, clear, and eXact description thereof, which will enable others skilled in the art to make and use the sanie,reference being had to the accompanying drawing forming part of this specification, in which- Figure l represents a side elevation, partly in section, of our improved electrical igniting apparatus. Fig. 2 is a plan or top view of the same.

Similar lettersrof reference indicate correspon ding parts.

This invention relates to a new arrangement of devices for bringing' the electric spark in contact with the jet of hydrogen gas which escapes from a zinc-and-acid reservoir similar to Vthat used in the Doebereiner lamp 5 and has for its object to dispense with the platinumsponge, which is expensive and too rapidly de'- stroyed, besides being easily affected by moisture or other change of temperature. Our invention consists in the connection, with the valve-lever pertaining to the said reservoir, of a projecting prong and one conductor of electricity. The other conductor leads to a serrated or corrugated plate, which projects from the top of the reservoir. When the lever is moved to open the valve and permit the escape of gas, the projecting prong is, by the same motion, brought in contact with the serrated plate, closing thereby the circuit, and

- producing a series of sparks which ignite the gas. The burning jet can be used to ignite other things, either the wick of a lamp, a taper, or other article. The prong and plate can be made of steel or other metal, and are more durable and reliable than the platinum-sponge.

A in the drawing represents the vessel or reservoir, within which hydrogen gas is created in the well-known or suitable manner.` B

is the cover of the vessel A. From it projects a tube', a, for the escape of the gas. b is a valve fitted through the tube a for preventing or regulating the escape of gas. C is a lever atlixed to the valve for turning the same. A spring, al, or weight tends to so hold the lever that the valve will be closed, as shown in Fig. 1. D is an electric battery of suitable construction. Itsvone conductor, E, is connected with the lever C, the other, F, with a plate or post, c, projecting from the upper end of the tube a. The plate e of the pivot of the lever C is insulated t'roni the metal of thetube, so that the electrical circuit will not be established unless the lever is brought in direct contact with the plate e. To facilitate this a projecting prong, f, is aflixed to the lever. Both the plate e and prong f can be made of steel or other suitable metal.

When the lever is swung up to open the valve the prong f is brought in contact with the surface of the plate e and moves over the same. We prefer to corrugate or roughen the surface of e so that greater friction and consequent lnore absolute contact will be produced when/the prong moves over the plate. Thev electric circuit is then completed, and the curl rent passes through the conductors. emitting sparks as it passes from f to e, or vice versa. As at the same time the valve a, has. been opened to permit an escape of hydrogen gas the sparks will come in contact with the gas, igniting the same, and enabling it to ignite other bodies.

Having thus described our invention, W'e claim as new and desire to secure by Letters Patent- The combination of the valve a, lever C, and prong f with the projecting plate e and el c tric conductors E F, all arranged to operate substantially as herein shown and described.

FRIEDRICH HEYL.
