GAS-LIGHTING- DEVICE.

Specification of Letters Patent. Patented NOV. 28, 1911.

Application filed December 8, 1910. Serial No. 596,363.

To all whom it may concern:

Be it known that I, JAMES M. CRowNER, a citizen of the United States, residing at Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Gas-Lighting Devices, of which the following is a specification.

My present invention relates particularly to devices for electrically lighting gas burners and my primary object is to provide a novel and inexpensive lighter, in which all springs and other delicate parts which are subject to quick wear, and likely to get out of order, are done away with.

A further object of my invention is to provide a movable contact point for the. striker arm, so constructed and counter-balanced, that it always hangs at the proper position for use, and in such manner that no springs or other additional means are necessary to maintain it in such position.

A further object of my invention is to provide a laterally adjustable support for the counter-balanced contact, having an offset to form a clearance between the burner and its body portion, for the free and easy movement of the counter-balancing weight.

A still further object of my invention is to provide a striker arm so located and connected upon the valve stem that it will not interfere with the operations of the valve key, and will permit of ready removal for the purpose of substitution.

With these and other objects in mind my invention, therefore, resides in the features to be hereinafter described and particularly pointed out with respect to the accompanying drawing, forming a part of this specification, and in which,

Figure 1 is an end elevation, and Fig. 2 is a side elevation.

Referring now to these figures, 5 designates the lower or valve portion of a burner upon which is screwed, as usual, the burner 6 carrying a tip 7 at its upper end. Transversely through the valve portion 5 extends a valve stem, upon one projecting end of which a nut 8 is threaded, and upon the opposite end of which is secured the button or key 9 by which the valve stem is actuated to turn on, or cut 0E, the flow of gas.

The striker arm 10 which I provide, has a lower and inwardly offset end 11 which is curled about and secured to the washer or nut 8 and is, therefore, positioned at one side of the burner farthest from the key or button 9. The upper angular end 12 of this arm extends above the burner tip 7 and has a swinging movement thereabove when the key or button 9 is turned.

Clamped between the burner 6 and the valve portion 5 is a disk 13, having an up wardly projecting tongue 14: between said burner 6 and the striker arm 10, and in line therewith, the upper portion of said tongue being in the form of a lateral extension 15, upon which is adjustably secured the lower end of a vertical supporting arm 16, and between which and said lower end of said arm 16 is disposed an insulating material 17. The upper and inwardly ofl'set end 18 of said arm 16 supports the pivot 19 of the contact arm 20, the upper end of which contact arm is in the form of a tapering finger 21, the upper end of which is always maintained in the path of swinging movement of the upper end 12 of the striker arm, and the lower end of which contact arm is in the form of a counter-balancing weight 22 which swings in the space between the vertical arm 16 and the burner 6.

From the foregoing it will be seen that as adjustment of the supporting arm 16 upon the extension 15 in order to cause the upper portion 12 of the said striker arm to pass over, and disengage from, the said finger 21 of'the said contact arm at a point adjacent and vertically above the burner tip 7, which is desired. Therefore, it being of course understood that the upright arm 16 and the striker arm 10 are connected to opposite poles of a generator, it will be seen that the disengagements of the said striker arm and the finger 21 will break the circuit previously established upon their contact, and thus de velop a spark which will ignite the gas flowing from the burner tip 7. The counter-balanced contact arm thus does away with all springs and other delicate parts usually employed, and the lateral adjustability of its upright supporting arm renders it easy to regulate the igniting spark in proper relation to the burner tip without bending or twisting either of the contact members as is usually necessary.

I claim:

The combination with a lighting fixture including a burner and a valve; of an arm movable with the valve and having a laterally extending extremity projecting across and above the burner tip, a support mounted on the fixture, an upstanding arm secured to the support, and having an ofiset at its upper end toward theburner, a contact device pivoted to the offset portion of the upstanding arm and having a finger extending into the path of the laterally extending extremity of the first-mentioned arm, and movable thereby across and above the burner tip, said parts swinging in different arcs and separating at a point above and adjacent to the burner tip, and a counterweight for the contact device, said counterweight being located in the space between the burner and that portion of the upstanding arm which is below the oifset thereof.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES M. CROWNER.
