SAFETY ATTACHMENT FOR GAS-BURNERS.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed March 4, 1908. Serial No. 419,074.

To all whom it may concern:

Be it known that I, HERMAN J. SGHOEN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety Attachments for Gas-Burners, of which the following is a specification.

My invention relates to improvements in safety attachments for gas burners.

Gas cocks of burners are sometimes turned to open position through accident or ignorance, allowing gas to escape into rooms and cause the death or sickness of the occupants, an explosion or if nothing worse, a waste of gas.

My invention therefore has for its object the provision of a simple, effective, durable and inexpensive attachment for gas burners, adapted to be attached or removed from gas burners with great facility and to prevent gas cocks from being turned to 0 en position through accident or ignorance, tiiereby eliminating, to a great degree, the chances of occurrences of the nature above mentioned.

In the drawings :-Figure 1 is a side view of a gas burner having my safety attachment applied thereon. Fig. 2 a vertical sectional view taken on the line 2-2 of Fig. 1. Fig. 3 a horizontal sectional view taken on the line 3-3 of Fi 1 showing the position the arm of my sa ety attachment occupies when looking the burner cock or preventing it from being turned to open position. Fig. 4 a horizontal sectional view taken on the same line as Fig. 3 and showing, in full lines, the position the arm of my safety attachment occupies after the burner cock has been turned to full open position and in dotted lines the position said arm occu ies when the burner cock is turned to partia y open position, and Fig. 5 a fragmentary detail view, on an enlarged scale, showing the screw for locking the arm which locks the gas cook, said screw being shown in full lines, in the position it occupies when looking said arm and in dotted lines in the position it occupies when withdrawn to allow said arm to be moved to unlock the gas cock.

Like reference characters designate corresponding parts in the figures of the drawin s illustrating my invention.

Tieferring to the drawings, 1 desi nates the body of a gas burnerwhich is secure to a service pipe and has a stop flange 2, 3 the burner cock thereof having a thumb and finger hold 4 affording means for turning it and a stop pin 5 adapted to contact with the stop flange, on one side of the body, when the burner cock is turned to or is in closed position. All of these parts and their operation being well known the above reference is thought sufficient and I will now describe the construction of my safety attachment and its operation in connection with a gas burner to pro duce the desired results above referred to.

My safety attachment embodies a support having a bottom 6 provided with a stop lug or abutment 7 extending upwardly from its forward end in the line of movement of the stop pin and adapted to be engaged thereby when the burner cock is turned to or is in open position, a long side 8 and a short side 9 integrally formed with said bottom at its rear end and a portion 10 hinged at 11 to the top of the short side and forming therewith a side of equal length to the long side, the portion 10 and that portion of the long side opposite thereto being curved so as to closely embrace the body 1 of gas burner and their upper ends abutting and being provided with threaded holes which receive the shank of a screw 12 and afford means for clamping the sides together and securing the support on the gas burner or for allowing it to be removed therefrom.

An arm 13 is fulcrumed on a pin 14 projecting upwardly from the rear end of the bottom 6 of the support, the forward end of said arm curving around one side of the burner cock 3 and the stop flange 2 in a horizontal plane and then depending downwardly in front of the thumb and finger hold iof the burner cock and having an enlargement 15 affording means for the engagement of the thumb to move the arm laterally and the horizontal portion of the arm having a shoulder or abutment 16 normally located in the path of movement of the stop pin 5 and bearing against one side thereof when the burner cock is in closed osition and preventing it from being turned to open position.

A screw 17 is inserted through a threaded hole in the side 9 in the same plane with the arm 13 and its end normally located far enough therefrom to allow said arm to be forced laterally to disengage its shoulder or abutment 16 from the stop pin 5 and permit the burner cock to be turned to open position and a spiral spring 18 is supported on said screw, one end bearing against the side 9 and the other end a ainst the arm 13, and serves to normally yieldably hold said arm in its normal inward position with its shoulder or abutment in engagement with the stop pin 5 and prevent the burner cock 3 from being turned to open position and yet allow the arm to be forced outwardly by the lateral pressure of the thumb against its enlargement 15 to disengage its shoulder or abutment 16 from the stop pin 5 and allow the burner cock 3 to be turned to full open position, bringing its stop pin 5 into engagement with the stop lug or abutment 7 on the support. hen it is desired to lock the arm 13 so as to hold the burner in closed position, the screw 17 is turned until its end comes into contact with said arm.

From the foregoing description considered in connection with the accompanying drawings it will be readily understood, assuming the parts of my attachment to be in the position shown by full lines in Figs. 1 to 4 inclusive, that the burner cock is locked in closed position and that it can be unlocked and turned to open position by forcing the arm laterally and returned to closed position and locked by turning it in the reverse direction, which will cause its pin 5 to ride against the arm 13 forcing it outwardly against. the action of the spring 18 and then allowing said arm to be forced inwardly again by the spring 18 when the pin 5 engages the shoulder or abutment 16 and it will also be understood from said figures of the drawings and Fig. 5 thereof that when the screw 17 is turned inwardly bringing its end against the arm that said arm will be locked.

What I claim is 1. A safety attachment for gas burners embodying a support adapted to be secured thereon and an arm fulcrumed on said sup port and having an abutment normally located in the path of movement of the stop pin of the burner cock and preventing said burner cock from being turned to open position and a depending portion located adjacent said burner cock and affording means for forcing said arm laterally to withdraw its abutment from the path of movement of the stop pin of the burner cock and allow said burner cock to be turned to open posi tion, substantially as described.
