JOHN M. ANCK, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRIC-LIGHTlNG GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 550,432, dated November 26, 1895.-

Application filed March 29, 1895.

T0 at whom it may concern.-

Be it known that 1, JOHN M. ANOK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful linprovement in Electric-LightingGas-Burners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a novel construction of electric-lightin g gas-burner, in which provision is made for the ignition of the gas by means of an electric spark caused by the contact of suitable electrodes near the burner, as hereinafter described.

It also consists of the novel construction and application of a spring to the key or cook which regulates the supply of gas, whereby the movable electrode can be temporarily held in any desired position.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a perspective view of an electric-lighting gas-burner embodying my invention. Fig. 2 represents a side elevation of the same, showing the igniting device in the act of forming a spark. Figs. 3 and 5 represent side elevations of the same, showing the movable electrode or wiper in the act of riding over the burner or tip out of contact with the stationary electrode. Fig. 4 represents a section through the key or cock, showing a spring employed for holding the actuating device temporarily in any desired position.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a gas-burner, the same having the tip B, while adjacent to the latter is secured in any suitable manner the stationary electrode O,which has its extremity slightly bent, as indicated in Figs. 1 and 2, said electrode being secured to the burner in the present instance by a clamp 0, between which and the burner asbestos or other similar material is interposed.

D designates the movable electrode or Wiper, which in the present instance is a continuation of the coil E, which is mounted on the member G of the lever or bell-crank F,

said wiper having its end D bent down wardly and outwardly, as indicated in Fig. 5. The other member H of said bell-crank is serial No. 543,616. (No model.)

mounted on the stem of the key or cook J by means of which the supply of gas to the burner is regulated, said bell-crank having its under portion provided with a notch therein, the walls K and L of which are adapted to contact with a pin or stud M, which is attached to a fixed point below said key, thus serving as stops.

N designates a flat spring, which is coiled about a nut or collar S and has its ends P crossed and partially encircling the stem of the key J, as will be understood from Fig. 4, the free ends of said spring thus holding said stem, cock, and bell-crank in any desired position.

Q designates a lever attached to a member of the bell-crank and having a weight R attached thereto.

The operation is as follows: \Vhen it is desired to ignite the gas, the wiper D is moved in the direction indicated by the arrow in Fig. 2, and the tip D thereof contacting with the stationary electrode 0, as shown in said Fig. 2, will cause a spark, and the gas being simultaneously turned on the same will be ignited, as is evident. If now it is desired to extinguish the fiame, the lever Q is pulled down, moving the wiper in the direction of the arrow in Fig. 3, whereby the end D thereof will contact with the tip B and will ride over the same, as best seen in Fig. 5, without contacting on its return with the electrode 0, thereby causing no spark on its return movement, as is evident. The function of the spring N will be apparent from Fig. 4, the free ends P of the same being in contact with the stem of the cook or key and holding the same and the bell-crank F temporarily in any desired position, as is evident, the weight R, attached to the member H of the bell-crank F, assisting to hold the latter normally in the position seen in Fig. 1, at which point the supply of gas will be cut ofi.

It will of course be understood that the supply of gas to the burner is cut off just before the wiper reaches the position seen in Figs. 3 and 5, so that the electrode D will not have its temper destroyed by the flame. Especial attention is directed to the feature of causing the movable electrode to ride over the tip B on its return movement without contacting with the electrode 0 in the manher described, whereby the unnecessary spark caused on the return movement of the igniting device is dispensed with, thus greatly prolonging the life of the battery employed, as is evident.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an electric lighting gas burner, a movable electrode or wiper having a bent portion near its extremity, a stationary electrode located adjacent to the tip of said burner in such position relative to the plane of move ment of said movable electrode, that when the latter is moved in one direction said electrode will contact, but their contact on the return movement will be prevented, by the bent portion of said movable electrode riding over said tip out of contact with said stationary electrode, substantially as described.

2. In an electric lighting gas burner, the 1 bell crank F having attached to one member 1 thereof a wiper having a bent end D, a st-ationary electrode C mounted near the burner, 1 said wiper being adapted to contact with the stationary electrode when moved in one di- 1 rection, and means for preventing their coni tact on the return movement, substantially.

, as described.

3. In an electric lighting gas burner, the bell crank lever Fhaving the members G and II, the member G carrying the wiper D, the' latter having the bent end 1) adapted to contact with the electrode C, the latter being arver having stops on its lower portion, a wiper 45 mounted on a yielding device on said lever, and having the bent end D, the stationary electrode 0 mounted adjacent said burner, the stem of the key or cock on which said lever is mounted, the pin M below said stem, 5 having the collar or nut S thereon, and the spring N engaging said collar, and having its ends crossed, and contacting with said stem,- substantially as described.

5. In an electric lighting gas burner, a cock 5 5 or key provided with a stem, a support below the same, a spring mounted on sand, support and having its ends crossed and engaging I said stem, substantially as described.

6. In an electric lighting gas burner, the spring N, having its lower portion bent into circular outline, and its ends crossed, and extended up beyond the line of intersection, substantially as described.
