ELECTRIC GAS-LIG HTER.

SPECIFICATION forming part of Letters Patent No. 638,753, dated December 12, 1899.

Application filed February 16, 1897. Serial No. 623,703. (No model.)

T0 at whom it may concern.-

Be it known that I, FREDERICK N. PIKE, of the city, county, and State of New York, have invented a new and useful Improvement in Electric Gas-Lighters, of which the following is a specification, reference being had to the drawings accompanying and forming part of the same.

The present invention relates to electric gas-lighting devices which are adapted to be secured to a gas-jet; and it consists of two electrodes respectively connected to the positive and negative poles of a source of electricity, one of the electrodes being movable toward the other to close the circuit and then break contact therewith at a point close to the point of emergence of the gas to ignite the same by the spark caused on the breaking of contact.

The object of my invention is to provide such a gas-lighting device which will obviate the necessity of the use of springs and provide a simple, cheap, and efficient construction for accomplishing the result aimed at.

In the drawings I have shown a construc tion embodying my invention, in which Figure 1 is a side elevation View of a gasburner provided with a construction embodying my invention, the parts being shown in their first position. Fig. 2 is a view similar to Fig. 1, but showing the electrodes in engagement with each other. Fig. 3 is a view similar to Figs. 1 and 2, but showing the electrodes after further movement when they have broken engagement; and Fig. a shows the movable electrode on its return movement to the position shown in Fig. 1.. Fig. 5 is a view similar to Figs. 1 to i, but taken at right angles to said figures.

Numerals of reference refer to like parts throughout the several views of the drawings.

Referring to the drawings in detail, 1 represents a gas-burner provided with a collar 2, which supports the electrodes 3 and 4, the electrode 3 consisting of a spring-wire mounted on said collar and insulated therefrom. Electrode 4 is pivotally mounted on one end of a lever 5, the other end of which lever is provided with an operating-pendant (3. The engagement-point of electrode 1 is provided with a catch 7, whtch engages electrode a and draws thesame over to a point close to a point of emergence of gas, as shown in Fig. 2. This electrode is suitably weighted at one side to insure its return to the first position after the operation, in the present instance a weight 8 being shown for that purpose. The slot 9 is provided in the lower portion of the electrode, through which works a pin 10, which, together with the lever 5, controls the path of movement of the electrode. The lever 5 is provided with a slot 11, through which passes a stud 12, secured to the collar 2.

13 represents a projection provided with a screw and nut for the purpose of securing the circuit-wires connecting the electrode 4 with the source of electricity.

The operation of the device is as follows: Assuming the parts to be in the position shown in Fig. 1, the operator drawing down the pendant 6 causes the electrode 4. to rise and to engage with the electrode 3, drawing over the said last-named electrode by means of the catch 7 to a point close to the point of emergence of the gas, as shown in Fig. 2, at which point the upward movement of the electrode is limited by the pin 10. The further drawing action of the pendant draws over the electrode still farther, withthe pin 10 as the point about which the electrode describes an are, this are movement of the electrode being permitted by the slot 11 until the parts arrive in the position shown in Fig. 3, which is the limit of the forward movement of the electrode 4. On releasing the pendant 6 the electrode i returns by the action of gravity to the position shown in Fig. 1 through a different path of movement to that taken on the forward movement, which return path also is caused by the lever 5 oscillating with the stud 12 at the opposite end of the slot 11.

N hat is claimed as new is In an electric gasigniter, the combination of a stationary electrode, a pivoted lever provided with a slot at its pivotal point, an electrode pivoted to one end of said lever and provided with a slot, a stationary pin projecting in said slot and serving as a center and guide for said electrode, and a weight carried by said movable electrode, said weight being adapted by the action of gravity, after In testimony whereof I have signed my the engagement of the movable electrode name to this specification in the presence of with the stationary electrode to cause a two subscribing witnesses.

movement of the lever on its pivot, whereby FREDERICK N. PIKE. the movable electrode will be returned to its I Vitnesses:
