' To all whom it may concern:

. way and closing the same.

Be it known that we, WILSON B. RUNNIoN and EDWARD RUNNION, citizens of the United States, residing at Spencer, in the county of Roane and State of West Virginia, have invented a new and useful Valve-Operating Mechanism, of which the following is a specification.

The present invention relates more particularly to means for controlling the passage of gas through supply. conduits or pipes. Under certain conditions, it is of the greatest importance to shut off the gas supply. For instance, the wall brackets are apt to be swung so that the flame from the burner will come into contact with the wall or adjacent combustible material, and cause a coni'lagration. A ain it sometimes happens that the supply of gas through mains is shut oil for some reason without warning. As a consequence, those burners which are in use are extinguished. When the su ply of gas is again turned on, the gas will pass through the burners, and it is apt to cause explosions or asphyxiation.

The principal object of the present invention is to provide novel, simple and practical means for automatically cutting oil the gas supply in such contingencies, thereby eliminatlng any danger of the above characters.

The preferred embodiment of the invention is i lustrated in the accompanying drawing, which is a sectional view through the apparatus, showing portions of the same diagrammatically.

A gas supply conduit 1 includes a valve casing 2, across which extends a partition 3 having an opening 4 therein surrounded by a valve seat 5. A guiding sleeve 6, preferably of insulating material, is fitted in one wall of valve 7, which closes the opening, and is movable into'and out of co'action with the valve seat 5, has a stem 8 rovided with a head 9 that is slidable in 516 guideway or sleeve 6.

An electro-magnet 10 has a core 11 snugly fitted in the outer end 'of the sleeve or-guide- This magnet is electrically connected, as shown at 12 with a suitable source of electrical energy 13. An-

other lead 14 from the said source of eleccate in this circuit. At 17 there is illustrated a-swinging wall bracket burner, which is connected to the supply conduit, and located upon the wall so as to intersect the flame from the burner should the bracket be is movableinto and out of engagement with spaced contact elements or arms 25 mounted on and insulated from the hood or cap 20, as shown at 26. The electric circuit above described includes the contact elements .25. The casing 2 is furthermore provided on the wall opposite the guide sleeve with a cap 27,

or packing box in which is slidably mounted a reciprocatory stem 28 having an outer knob 29am] an inner enlarged head 30, this head being movable through the opening and into engagement with the valve stem 7.

The operation of the structure is substantially as follows: Assuming that. there is pressure in the pipe 1, the diaphragm 21 will he raised so that the outer end of the stem 23' is in engagement with the arms 25. 1f

therefore the switch 15 is closed, the circuit will be closed. Therefore the magnet will be energized, and if the head 9 ofthe valve is in coacting relation with the core H, the valve 7 will be supported in open position, as shown. Assume now that the gas is burning at the bracket 17. If said bracket is swung to the wall, the flame will immediately fuse the conductor 18, and. thereby break the circuit. As a consequence, the magnet will be den'ergized, permitting the valve 7 to drop and close the opening 4, thus cutting off the supply of gas and extinguishirn the flame before dal'nage is done. ()r with the parts,- as shown in the drawing, assume that the supply of gas is cut oif and that there areburners in operation, it will be evident that the pressure in the conduit 1 will be reduced,

thereby permitting the diaphragm 21 to fall. .The stem 23 will gravitate and disengage until the stem 28 is forced upwardly and the valve returned to open position with the head 9 in coacting relation to the electromagne't. If in an emergency, it is desired to manually cut off the supply of gas, it is only necessary to open the switch 15. It will thus be evident that simple mechanism is employed, which materially reduces the dangers above described due to the use of gas.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be a parent to those skilled in the art without urther description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. I
