ELECTRlC GAS-LIGHTING BU RNER.

SPECIFICATION forming part of Letters Yatent No. 272,004, dated February 6, 1883 Application tiled August 9, 1882.

To all whom tt may concern:

Beit known that 1, HENRY J. WARREN, a citizen ofthe United States, residing at West Bridgewater, in the county ot Plymouth and State of Massachusetts, have invented certain Improvements in Electric Gas-Lighting Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a perspective View of an electric gas-lighting burner constructed iii accordance with my inven tion, the stop-cock being closed. Fig. 2 is a vertical section thron gh the center ot thesame. Fig. 3 is ahorizontal section through the same on the line .r wot' Fig. 2. Fig. 4 is a plan with the stop-cock open.

My invention relates to an improvement in the construction of gas-burners, more particu lai-ly those known as electric gas-lighting burners; and it consists in a gas-burner in which the pillar or main upright portion is formed by a prolongation of the plug of the stop-cock, which is arranged vertically within the shell, below which it is provided with a thumb-piece or handle, by which it may be turned with the upright portion ofthe burner by hand to let on and shut oli` the gas; and my invention also consists in the combination, with a gas-burner so constructed, ot' an independent movahle electrode, which is wiped or swept into and out of contact with a fixed electrode, to produce the electric spark to ignite the gas, by means of a pin or projection sccured to or connected with the rotating vertical portion of the burner, which latter, as it is turned with the stop-cock to let on the gas, is thus caused to actnate the independent movable electrode to produce the iguitin gspark as required.

In the said drawings, A represents the hollow pillar or main vertical portion ot a gasburner, which is provided, as usual, with a tip, (t, and is formed by a prolongation or upward extension of the plug b ot' the stop-cock, and in the same piece therewith, the plug b heilig arranged vertically within the shell B, on one side ot' which is the supply-pipe c. The plug b is made slightly tapering, and its stem d extends down below the shell B,and has secured to its lower end by a screw, e, a thumb-piece (No model.)

or handle, j', by which it can be turned by the hand to let on or shut off the gas, a spiral spring, g, bearing on a washer, 10, being interposed between the thuinbpiece fand the under side ot' the shell B, which serves to keep the plug b snugly down upon its seat. The plug b is made hollow, and communicates with thestraight longitudinal passage. through the vertical portion A ot' the burner, and in the side ot' the plug b is formed an aperture, i, which communicates with its interior, and is so placed that by turning the plug it can be brought into line with the gas-inlet passage k or out ot' line therewith to let on or shut oli' the gas from the portion A, as required.

To one side ot' the shell B is secured an insulating-block, m, from which rises the tixedelectrode D,which is connected, as usuahwith one pole of the battery, and extends up to a point in close proximity with the oritice at the tip of the hunner, the terminal or contact point of this electrode being composed of a piece ot' spring-wire, 15, having its inner end coiled around the upper end of the main portion D, and secured thereto in any suitable manner, by which means it is rendered suflicien tly elastic to enable the arm or movable electrode E to be readily wiped past it, as it is moved into and out of contact therewith, to produce the electric spark to ignite the gas in the following maniier: The movable electrode E, which is connected through the burner and gas-pipe with the other pole ot` the battery, is united by a thin flat spring, n, to a short stud or pin, 12, rising from the shell B, the spring n serving to maintain the arm E in the vertical position seen iii Fig. 1, and allow it to yield freely in opposite directions.

instead ot' being constructed, as shown, with a spring, n, the movable electrode may, if desired, be composed of a single piece of spring metal of suitable thickness and elasticity, secured at its lower end to the shell B.

q is a pin or projection, which is secured to the side ot' the rotating pillar or vertical por' tion A of the burner, and extends outward horizontally to such a distance that its end will intercept the movable electrode E, and, the parts being in the position seen in Fig. 1, as the vertical portion A of the burner is rotated with the st0p-cock in letting on-the gas,

IOO

the pin q is broughtinto contact with the movl able electrode E, and vibrates the same, so as to cause its terminal point 16 to be wiped past the elastic terminal ot' the ixed electrode D, thus producing the spark to ignite the gas, the cock being open when the parts are in this position. As the portion A of the burner continues to be rotated, the pin gis carried out of contact with the movable electrode, which is then automatically returned to its original vertical position by the spring n; and on the return movement of the pin (l, when the stopcock is rotated to shut oi the gas, the pin q is again brought into contact with and slips by the movable arm E, which yields freely against the resistance ofthe spring u, to allow the pin q to he carried back to the position seen in Fig. 1, ready to again actnate the arm E, as bet'ore described. By this construction and arrangement ot' parts the electrodes are not liable to be left in contact, as they are removed a sufficient distance from each other when the stop-cock is turned to its full extent in either direction, or when the gas is turned down to its lowest point, there being no contact made l between the two electrodes on the return movement ot' the cock to shut otf the gas.

1' is a pin which is alternately brought into contact with pins s t, which thus serve as stops to limit the movementot' thc stop cock in either direction.

I am aware ofthe United States Letters Pat ent granted to E. McClintock March 3112568, and to G. W. Tinsley May ll, 1875, and therefore make no broad claim to the prolongation of the plug ot' the stop-cock above the top ot' the shell ot' the burner, nor to any ot' the devices or construction shown in said patents; but--` What l claim as my invention, and desire to secure by Letters Patent, is-

1. A gas-burner having its straight pillar or main outside upright portion, A, which carries the tip a, formed by the prolongation or upward extension of the plug b ot' the stop-cock, arranged vertically within the shell B, in combination with a thumbfpieceor handle, secured to the stem of the cock below the shell B, by which the plug b and the pilla-r A, with its tip a, may be rotated together, substantially as described.

2. The combination, with a gas-buruer having its pillar or vertical portion A formed by the prolongation or upward extension ot' the plug of the stop-cock, arranged vertically withiu the shell, and provided with a thumb-piece or handle below the same, ot' an independent movable electrode, E, adapted to be wiped or swept into and out ot' contact with a tixed electrode, to produce the spark to ignite the gas, by means of a pin or projection secured to or connected with the rotating vertical portion A ot' the burner as the latter is turned with the stop-cock to let on the gas, substantially as set forth.

The combination, with the rotating rertical pillar or portion A ofthe burner provided with a pin or projection, q, of the spring arm E, forming the movable electrode, and adapted to yield in opposite directions when struck by the pin q to allow the latter to be carried past it and .return automatically to its original position when the pin g has passed out of contact therewith, substantially as dcscribed.

Witness niy hand this 5th dny ot' November, A. D. 1880.
