GAS LINE VALVE Filed June 5, 192a ends of the pipes 3, 2 respectively.

Patented Mar. 11', 1930 UNITED STATES- moo]; LERNER, or CHICAGO, ILLINOIS GAS-LINE VALVE Application filed .Tune 5,

This invention relates to improvements in gas line valves and its chief object is to provide means in a gas line for positively cutting off the gas supply to the burners, when desi'red, of a gas range or the like so thatchildren can not open the gas burners and permit the gas to escape and so jeopardize the lives, as well as the property, of the household.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claim and illustrated in the drawing which forms a part of this application for patent and in which- Fig. 1 is an end view of a gas range showing the application of the valved coupling to the gas line.

Fig. 2 is an enlarged view of the valved coupling in side elevation.

Fig. 3 is a cross section through the valved coupling.

Fig. 4 is a vertical sectional view through the coupling at right angles to Fig. 3.

Fig. 5 is a face view of the valve key.

Like reference characters denote corresponding parts throughout the several views.

The small children of a household, in their play, frequently tamper with the gas range and open and close the gas burners for amuse- The present valved coupling is adapted to connect the gas line 2 with the range-supply pipe 3 and it comprises an angular or L- shaped casting 5 formed in its ends with the threaded bores 6, 7 to receive the threaded channel or passageway 8 is formed in the casting and connects the threaded bores 6, 7 and extending transversely through said passage- Way and through the casting and terminating in lateral recesses 9, 10 of the casting is the A gas 1928. Serial No. 283,099.

bore 11 that snugly receives and is co-extensive with the transversely extending valve 12 formed with the transversely extending valve port 13 that, in one position of said valve known as the open position, registers with the gas passageway 8; and that in another position of said valve known as the closed position is out of register with the gas passageway 8.

Secured by rivets 14 to one end of the valve 12 and disposed in recess 10 is the portion 15 of an arrow, the head 16 being secured to one face of the casting at the periphery of said recess in such position that when the valve is in open position the head and portion 15 of the arrow are aligned to denote that the valve is open and the gas line clear. In the closed position of the valve, shown in Fig. 2,

the body 15 of the arrow is in a position at right angles to the head. Stop lugs 16, 17 in the recess 10in the path of movement of the arrow portion 15 limit the degree of its movement with the valve.

A flat disc 18 seats in the casting recess 9 and upon one end of the valve and is retained in position by a screw 19 extending therethrough and into the valve, a coil spring 20 upon said screw bearing against the disc to cause it to yieldingly resist the turning movement, this resistance causing the valve tofrictionally hold any adjusted position in the bore 11. A key 21 formed at one end with prongs 22 is adapted for engagement with thearrow portion 15 to move thesame from open to closed position and vice versa. This key is kept in an out of the way position inaccessible to unauthorized persons or chil-.

' drento preventthem from, at any time, turn:

ing on or ofi the valve 12.

What is claimed is In a valved gasline coupling, an angular casting having threaded bores in its ends to receive the gas pipes and a gas passageway connecting said bores, the lateral faces of said casting being recessed, a valve extending transversely through said casting and through said gas passageway and terminating flush with the said casting recess, said valve being formed with a port adapted to pass into and out of registry with said gas passageway, a pointed indicator head fixed to said casting contiguous to one lateral face recess, stop lugs located in the said lateral face recess, one of said lugs being disposed contiguous to said indicator head and the other lug remote therefrom, an indicator body portion fixed to and movable with said valve,

the ends of said body portion extending into said lateral face recess for contact with said stop lugs and, in one position of said valve, for cooperation with said indicator head, a friction disc adjustably secured to the opposite end of said valve and bearing against one face recess, and a key for rotating said valve.
