CHARLES D. P. GIBSON, OF NEW YORK, N. Y.

ELECTRICAL GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 238,383, dated March 1, 1881. Application filed September 28, 1880. (No model.)

To all whom it may concern Be it known that I, CHARLES D. 1. GIBSON, a citizen of the United States, residing in New York city, in the State of New York, have invented certain new and useful Improvements relating to Electrical Gas-Lighters, of which the following is a specification.

My improved lighter is adapted for those situations where the hand of the attendant may be applied separately to each burner, or to a wire connected to each, to effect the lightmg.

The improvements lie in the means of insulation and of supporting the lever which makes and breaks the contact, and in the connecting of the parts for accomplishing the latter end. The lever carries a spring-arm, projecting laterally therefrom. The lighting motion sweeps this lever across a stop, which is insulated and put in electrical connection with a suitable battery, while the lever and its spring-arm are in connection with a system of gas-pipes and with the ground. It follows that at each motion of the spring-arm, in either direction past the stop, it makes and breaks the circuit, so as to induce a spark. This takes place so near the burner and in such relation thereto as to ignite the gas.

The following is a description of what I consider the best means of carrying out the invention.

The accompanying drawing forms a part of this specification, and represents the novel parts with so much of the ordinary parts as is necessary to show their relation thereto. It is a side view on a large scale.

Referring to the figure and to the letters of reference marked thereon Ais the gas-bracket, threaded, as usual, to receive B, which is an ordinary burner. The screw-threaded portion of the bracket A is sufficiently long to allow of the insertion of a washer in the joint between the tip B and the bracket A. I employ a piece of brass or other suitable material, of which the base D is practically a washer, and is held firmly in the joint between A and B. The upright portion or body D is in one with the washer D, and forms the support for the pin or pivot E and the spring F, as also for the screws G, which hold the upright bar E. On the pivot E is mounted a bell-crank lever,

M, certain portions of which will be designated by additional marks 1 M operated in one direction by a wire. I, pulled by hand, attached to the arm M, and in the other direction by the spring 13. The other arm, M is at each vibration moved in a path approximating the gas-jet.

J is a slender wire, of spring-brass, coiled around the arm M and fastened at the point 9', terminating with an extension toward the burner, as shown, constituting a spring-arm adapted to come in contact wit-h the bar H, and induce sparks at each making and breaking of contact with the upright H.

K K are stop-pins fixed in D to meet the corresponding shoulders on the vibrating part M, and prevent its being turned too far in either direction.

L is a wire leading from a battery (not represented) and connecting with the upright bar H at the point I. This bar is insulated from the body D and also from the screws G G, by hard rubber T, the same lying in a sufficiently thick layer between the bar H and the part D and also lying under the head of each screw, and extending inward through the bar around each screw-shank.

It will now be understood that all the electrical parts are mounted on the piece D, and applied and removed with it. The entire mechanism may be removed from any gas-fixture by simply unscrewing the burner B off the threaded end of the bracket A, and then lifting off the part D and its connections. Similarly my entire apparatus may be applied to any ordinary gas-fixture by simply applying gas-tongs and unscrewing the burner B, then slipping upon the threaded end of the bracket A my piece D, with its several attachments, then applying and firmly screwing down the burner B again.

My invention requires no special kind or form of burner. Gas-fixtures are of so nearly uniform size that one size of my mechanism may be made to serve for all. If, however, there should be cases where the threaded portion of A should be of much greater or less size, or if the length of the burner should be much greater or less than usual, I propose to make and supply a correspondingly modified size of my mechanisms.

The parts may be made rapidly and cheaply bysuitable machinery, and may be applied together with little labor or expense. The application to a burner is as will be seen, an unusually simple operation.

I claim as my invention The washer 1), bearing the upright D in combination with the pipe A and screw-tip B, and the arms M M M mounted upon the upright D and the insulated bar H, mounted upon the same upright, and electric connection L and spring F, all arranged so that the action of the spring will keep the connection broken by drawing the bar M toward the upright, as set forth.

In testimony whereof I have hereunto set my hand at New York city, N. Y., this 14th day of September 1880, in the presence of two subscribing witnesses.
