SAFETY DEVICE FOR GAS VALVES.

Application filed January 22, 1926. Serial No. 82,988.

This invention relates to gas burner valves, the invention having more particular reference to a novel type of attachment for gas burner valves.

The invention has for an object the pro vision of an improved attachment for gas burner valves which will prevent the gas from being turned on accidentally.

A further object is to provide a device of this nature which may be readily attached to the ordinary gas burner valve, as in general use. 7

Another object is to provide an attachment of this nature of novel simple 0on struction and arrangement of parts.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the fol- V lowing description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing shows a perspective view of a gas burner valve with my improved attachment in place thereon.

Fig. 2 of the drawing shows a perspective detail view of the attaching screw.

Fig. 3 of the drawing shows a similar view of the support. 7

Fig. 4 of the drawing shows a perspective detail view of the rear of the support as shown in Fig. 3. g

Fig. 5 of the drawing shows a perspective detail view of the operating lever.

Fig. 6 of the drawing shows a perspective detail view of the operating lever screw.

Fig. 7 of the drawing shows a perspective view of the operating lever spring.

Fig. 8 of the drawing shows a perspective 40 view of a gas burner valve with a modification of my improved attachment in place thereon.

The body member 10, having an inlet 11,

outlet 12, valve proper 13. held in position by a screw 14: and spring 15, and havinga I handle 16, and a pin 17 located in the elongated slot 18, are of common ordinary construction such as generally used in gas burner valves.

As here embodied my improved attachment comprises a support 19, or bracket, of any suitable shape, having a protruding portion 20, preferably of cyllndrical construction, at one extremity, and a second similar protruding portion 21, at its other extremity.

The operating lever '22 has a button 23,

or any similar suitable extended portion, at

one extremity, and a finger 24', projecting at a right angle to the operation lever 22, at its other extremity.

The operating lever spring 23, of any suitable number of coils, has two protruding extremities 24 and 25, at right angles thereto.

It :will be understood that the gas burner handle 16, and the support 19, are attached to the valve proper 13, by the attaching screw 26, which has a suitable slotted'head 27, and a threaded portion 28, the said attaching screw being similar to the screw ordinarily used to attach the handle 16, but of sufficient additional length to accommodate the support 19, which is provided with an aperture 29, centrally located in the heretobefore mentioned protruding portion 21,

and acircular recess 30, centrally located with the aperture 29, and opposite to the protruding portion 21. It being further understood that the protruding portion 21 will engage in a recess located in the valve proper 13, to ordinarily receive the inner extremity of the handle 16, and that the inner extremity of the handle 16 will engage in the recess 30, of the support 19. The operating lever 22, is pivotally attached to the support 19, by the operating lever screw 31, having a suitable slotted head 32, and a threaded extremity 33. It being understood that the operating lever 22 has an aperture 34, suitably located, at or near its center, to receive the said operating lever screw 31, and that the support 19 has a threaded aperture 35, centrallylocated in the hereto-before mentioned protruding portion 20, of the support 19, to receive thethreadedextrem- 'ity 33 of the operating lever screw 31, as a means of pivotally attaching the operating lever 22 to the support 19, as hereinbefore set forth. The operating lever spring23, is positioned over the heretobefore mention protruding portion 20, of the support 19, and has its protruding extremity 24 located under the operating lever 22, and its other protruding extremity 25, located over the support 19, so as to normally hold the heretobefore mentioned finger 24 of the operating lever 22 in engagement with the heretobefore mentioned elongated slot 18 of the gas burner valve body 10.

It will be further understood that the above mentioned construction is such as will normally hold the valve proper 13, in a closed position, as clearly shown in Fig. 1, of the accompanying drawing, and that the valve proper 13, can not be opened until the linger 21 of the operating lever .22 is dis engaged from the elongated slot 18 of the valve body 10, by pressing the button :23 of the operating lever It being clearly understood that the linger 2d of the operating lever 22 will normally engage the elongated slot 18 of the valve body 10, direetly adjacent to the extremity of the said elongated slot 18, opposite to the pin 17, for the purpose as hereinbeitore set forth.

Referring in particular to Fig. 8 of the accompanying drawing, in which I have shown a modification of my improved attachment. The heretobel ore mentioned operating lever 22 has an upper protrudirn por tion 36, located directly above the heretobefore mentioned finger 2st of the operating lever, the adjusting screw 37, has a suitable slotted head 38, and is threadedly attached to a threaded aperture located in the upper protruding portion 36 of the operating lever as at 39, so that extremity 10 :is in contact with the heretobeiore mentioned pin 17, a look nut 41 being provided to hold the adjusting screw 37 in the desired position.

It being understood that the above described construction will mirn'ially hold the heretobelore mentioned valve proper 12) in a fully closed position, in event of any slack or play in the heretobefore described construetion, which might allow the valve proper 13 to be slightly or partly opened when the linger 2 1 oi the operating lever 19 is normally engaged in the elongated slot 18 01' the valve body 10.

Having); thus I claim new ters .atent oi lows:-

The combination with a valve having a slot therein, oi. a valve stem, a pin in said stein adapted to travel in said slot, a lever mounted on said valve stem, a spring; l on norn'ially urging the inward portion of said lever downwardly, an adjustable locking and desire to protect by Letthe United States is as folzneans screw threaded in said lever in position to engage said pin for holding said valve stem in a predetermined position, and means for fixing said adjustable locking means in an adjusted position, said lever being: manually operable to release said pin for permitting movement of said valve stem in testimony whereof I have allixed my signature.
