Application filed June 24, 1929. Serial No. 373,357.

V mechanism, making it inexpensive to manufacture.

With the above and other objects in view the invention consists in the automatic lighter for burners as herein claimed and all N equivalents.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts in different views,

Fig. 1 is a central sectional view of an automatic lighter for burners constructed in Y accordance with this invention, the valve thereof being in the closed or normal position' Fig. 2 is a similar view with the valve in the open position caused by the opening of a burner valve reducing the pressure in the supply pipe, and

Fig. 3 is a plan view showing the usual relation of the lighter to the burner.

In these drawings, 10 indicates a gas supply pipe or manifold, which, in the case of a gas range, supplies a plurality of burners 11 controlled individually by their valves 12.

A casing 13 has a threaded connection 14: with 1735 the supply pipe 10 and is provided with a cup-shaped cover member 15 with a gasketed diaphragm 16 between them, said diaphragm dividing the casing and its cover into a lower pressure chamber 17 and an upper counter pressure chamber 18. Between these two chambers there is restricted open passage afforded by a passageway 19 in the cover member controlled by a needle valve 20 and communicating through registering openings in 5 the diaphragm and its gaskets with a passageway 21 in the casing member. A valve seat 22 formed in the casing member 13 has a pipe 23 connecting it with a pilot 24 in which there is normally maintained a low 0 pilot flame which develops into radiating jets 'ing to the communication through passageneedle valve 36.

of burnenlighting flame extending to the burners 11 upon the opening of an automatic valve admitting greater gas pressure thereto.

A set screw 25 is threaded through the casing 13 into the pressure chamber .17 so as to be capable of adjustment, with a lock nut 26 thereon for maintaining its adjustment. Within the chamber 17 a yoked member 27 is swiveled on the end of the screw 25 and forms the fulcrum fora valve lever 28 having 'a conical pilot flashing valve member 29 pivotally mounted on one endand having a yoke at the other end with slot and pin connection to a stud 30 anchored to the center of the diaphragm 16. A coiled spring 31 has.

one end connected with a spring clip 32 swiveled on the anchor stud 30-and its other end engaged by the end of a screw 33 adjustably threaded through the cover member 15 and provided with a set nut 3&1 for locking it in I its adjustment. The action of this spring is to hold the valve closed'on its seat when the gas pressures above and below the diaphragm are equalized, which is the normal state 0W- way 19,21.

For maintaining the normal small pilot light there is a by-pass around the valve formed by a passageway 35 controlled by a In operation the opening of a burner valve 12 causes areduction in pressure within the supply pipe 10 and therefore within the pressure chamber 17 but, owing to the limited capacity of the passageway 19, 21, the reduction in pressure in the chamber 18 is gradual and for a short time it exceeds the pressure in chamber 17 to flex the diaphragm 16 and cause thevalve toopen and admit a greater volume of gas to the pilot, causing it to flash the valve and restore the parts to their normal positions ready for the next operation when a burner valve is opened.

The period of duration of the lighting flame may be varied by the adjustment of needle valve and the proper adjustment of the valve and the spring may be made by 5 adjusting screws and 33 respectively.

The burner lighter of this invention isoof simple,.inexpe nsive construction but is durable and free from parts likely torequire attention so as to render service indefinitely in the automatic lighting of iburn'ers .whenever their valves are opened. I V

lVhile, for convenienceof illustration, the needle valves 20 and 36 arerepresente'dasdi ametrically opposite, itmay be preferredto 15 locate them otherwise, such as 90 apart.
