The primary object of the invention is to provide means acted upon by the gas flame to holdthe gas valve open, said means closing said valve when the flame'is extin- I" I guished.- y

Inthedrawings, :lt) designates the gas I i burner, gas beingadmitted to the same by the valve 11, actuated bythe valve rod 12. A bracket 1a is secured to the burner said bracket being formed of a single piece of metal the body portion of which is bent to embrace the burner, the apert-ured extensions of said body portion being connected by the screw 16, in order that the same mayfbe clamped upon the burner. The arm 17 of the bracket is offset from the same and egg tends upwardly, and secured to said. arm is a bar 18 which is formedintermedi" ateits ends with a yoke19. This bar is secured at either end to a vertically extending arm 20 the lower ends of thearms 20 beingcurved to engagetjhe sliding weighted member 26. A second bar 24, similar in construction to the bar 18, is secured to said arm, and the two bars combine to form a guide for said sliding weighted member. This sliding weighted member 26 is provided with the head 27, to prevent the same from falling between the transverse bars 18 and 24, the end portion of the bar being connected to the valve rod 12 as shown in detail in Fig. 1. The yoke 28 has, its end portion connected to the upper terminals of.

the arms 20, said yoke extending over the burner.

The burneris lighted after the valve rod 12 has been lifted, said valve rod being held Specification of Letters Patent. Application filed January 15, 1912. Serial'No. 671,179.

until the yoke to expand. When this yoke has expanded,

moved to grasp the slidingmember 26, the

force the same into contact with the sliding t-ainedinits expanded position the sliding valveo'pera'tor will be held raised, the valve being maintained open.- To close the valve, the rod 12 is manipulated and meg sliding. valve operator-allowed to fall. It will be noted that should the flame be extinguished and contraction of the'yoke 28 willlseparate the lower terminals of the arms 20, permitvalve and out 01f the supply of gas.

It will be seen that a construction of this character will cut ofi the flow of gas should the flame be extinguished-without manipulating .the valve. Attention is also called to the fact that the device may be easily and economically constructed, being readily applied to burners now in use. r

What is claimed is:

the gas burner, a bar supported by said )bracket, a plurality of arms pivotally sup-' ported by saidbar, a second bar connecting diate their ends with yokes,a weighted valve operator slidably mounted between said bars, the terminals of said' arms being offset to contact with said sliding valve operator,
