To all whom it may concern: groove a, formed in the wall of said recess. Be it known that I, FRANK \V.

The upper seating recess a formed therein. The valveportion a of the casing is in the form of a recess is in the form of a vertical passage cap for the chamber a and is preferably I00 50 closed at its lower end, except for a small inscrew-threaded, so as to screw into the same. let-port a that communicates With a vertical This cap is provided with a screw-threaded hollow burner attaching-nipple a ,a supplypassage (W, and a screw at, the latter to accommodate the upper end of the valve cylinder or stem as the latter is partially lifted from its seat by the pressure of the gas. It is this lifting of the valve from its seat that reduces the friction of operation to the lowest point and produces a valve susceptible to the slightest electrical influence.
In the form of my invention illustrated in Fig. 4 the armature of my valve is formed all of one piece of soft iron. Otherwise the con struction and operation is substantially as heretofore described. In setting the device up the two electromagnets are connected to independent circuits, so that either one or the other may be operated at the will of the operator. IVhen one is operated, the valve is oscillated in one direction, turning up the gas. \Vhile the other is operated, the valve is oscillated in the opposite direction, turning the gas down to its lowest point and leaving only the usual pilot-flame burning. The switch or buttons for operating the circuits may be located in any desired position most convenient for operation. I do not care to limit myself to this valve operating in a vertical position, as it may be equally well employed in such places as where it is necessary for it to be placed horizontally. The cylinder, with its cut-away portion, could also extend up with the armature at its lower end with equal facility and exactness of operation. This device is designed particularly for use with WVelsbach burners, as the mantles are thereby not subjected to the shock incidental to other methods of ignition. As has before been mentioned, the upward pressure of the gas upon the valve partially lifts it from its seat and thus reduces the friction to a minimum.
It will be observed from the above description that the cap covering the valve-chamber is removable without in any way disturbing the valve or the magnets and wiring, said cap being entirely free of the same. After the cap is removed the valve can be lifted out bodily to be cleaned and oiled without disturbing the magnets or the wiring.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a gas-regulatin g cock the combination with a casin g, of an oscillating valve mounted therein and adapted to control the gas-supply, an armature mounted upon said valve, and electromagnets applied in the casing so as to exert their force upon the armature at a tangent to its direction of rotation or oscillation, substantially as described.
2. In a gasregulating cook the combination of a separable casing, an oscillating valve mounted therein and having a pendent cylindrical portion with a flattened side adapted to bring the valve-openings into communication with each other, and electromagnets for oscillating or partially rotating said valve either in one direction or the other, substantially as described.
3. I11 a gas-regulatin g cock the combination of a casin g, a valve mounted therein and comprising a vertical cylinder having a flattened side adapted to bring the valve-openings into communication, and an. armature on said cylinder, and electromagnets applied in the cats ing so as to eXert their force upon the armature at a tangent to its direction of rotation or oscillation, substantially as described.
4. In a gas-regulatingcock the combination of a casing having a hollow chamber, avertical recess, an inlet-groove formed in said recess, and a passage from said recess to said chamber, a rotary or oscillating valve mounted in said recess and provided with a flattened side to bring the passage and inlet-groove into communication either more or less, an armature on said valve and electromagnets for operating said armature to turn the valve either one way or the other, substantially as described.
5. In a gas-regulatin g cock the combination of a casing comprising two separable parts, one of the parts being provided with a hollow chamber communicating with the gas-supply, a valve in said chamber for regulating the supply, and provided with an armature, electromagnets for actuating the valve, the other member of the casing being adapted to be removed from the lower member without breaking the connections or disturbing the magnets substantially as described.
In testimony whereof I hereunto affix my signature in presence of two witnesses.
