THOMAS A. PAYNE, 0F BRIDGEPORT, CONNECTICUT.
AUTOMATIC CUT-OFF FDR GAS-BURNERS.
Application filed December 6, 1916.
To all whom it may concern:
Be it known that I, THOMAS A. PAYNE, a citizen of the United States, residing at Bridgeport, in the county of Fair-field and State of Connecticut, have invented a new and useful Improvement in Automatic Cut- Offs for Gas-Burners; and I do hereby declare the following, when taken in connec tion with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, 111- Figure 1 a side view of a gas-fixture illus trating the location of my improved automatic cut-off.
Fig. 2- a vertical sectional view of the automatic cut-off detached.
Fig. 3 a perspective view of the valveoperating arm, detached.
This invention relates to an improvement in automatic cutoffs for gas burners particularly adapted for burners used in connec tion with prepayment meters. It has many times occurred that the meter runs down when the cock at the burner is open, and then when a coin is dropped in the meter the gas escapes through the burner.
The object of this invention is to provide means for closing a valve between the cock and the burner which valve will be closed by the pressure of gas; and the invention consists in the construction hereinafter described and particularly recited in the claims.
In carrying out my invention, I employ a body 3 which is located in a gas-fixture 4: between the coc 5 and the burner 6. As herein shown the body 3 is connected at its lower end with a coupling-piece 7 so as to provide a bottom chamber 8 between them. This chamber connects at the bottom with a gas-supply pipe 9 of the fixture. At the top of the body is a burner-cap 10 forming a chamber 11 between the upper end of the body and the cap, and this cap is recessed and threaded to receive the burner nipple 12. In the body is a transverse valve-chamber 13 provided at one end with a tapering valve-seat 1a which is formed in an offset 15 and the chamber is closed at the opposite end by a plug 16 entering an offset lug 17. In the valve chamber is a tapered valve 18 adapted to enter the seat 14: and this valve has a handle stem 19 projecting beyond the Specification of Letters Patent.

ofi'set or extension 15, and an inwardly extending stem 20 the end of which is supported in a hole 21 formed for it in the plug 16. Around the stem is a spring 22 one end of which bears against a washer 23 fixed to the stem 20 and the other end against the plug 16, the tendency of the spring being to force the valve into its seat. Connected with the valve is an arm 2& the end of which extends over the upper end of a vertical passage 25 which connects the valve-chamber 13 and the bottom chamber 8, and in this passage 25 is a float 26 for the purpose as will hereinafter appear. The arm 21 is formed with a small opening 27 near its outer end adapted to engage with a beveled pin 28 projecting into the chamber 13. To prevent the valve stem from turning so as to keep the end of the arm in proper relation to the passage 25, the valve-stem is provided with a key 29 entering a keygroove 30 in the plug 16. The passage 25 is connected with the valve-chamber 20 forward of the valve 18 by a port 31, and the valve-chamber 20 is connected with the upper chamber 11 by a port 32 extending from the valveseat 14. Under normal conditions the float 26 will stand in the passage 25 above the port 31 so as to allow gas to enter the port 31 and escape through the port 32 to the burner. Should the supply of gas be out 011', the float 26 will drop to the lower end of the passage 25. When the supply of gas is turned on, the float 26 will rise rapidly and the momentum will be suflicient to lift the outer end of the arm 21 ofi from the pin 28 allowing the spring 22 to act to force the valve 18 into the seat 1 1 and thus close the port 32 preventing the escape of at the burner. In order to light the gas it will then be necessary to push in the handle end 19 of the valve stem inward, which will open the port 32, and this valve stem is pushed in until the hole 27 in the arm 24 engages with the pin 28which locks the valve in its open position. The pressure of gas will then hold the float 26 above the port 31 allowing the free passage of gas to the burner.
It will thus be seen that if the gas cock 5 is open and there is a supply of gas, the pressure of the gas will lift the float so as to close the safety cut-0E and prevent the flow of gas to the burner.
I claim 1. An automatic cut-off for gas-burners comprising a body located between the burner cock and the burner, said body formed with a transverse valve-chamber provided with a valve-seat, a valve in said chamber and adapted to enter said seat, a vertically arranged passage communicating with the source of supply and with said valve-chamber, means for holding the valve in the open position, a float in said passage independent of the valve adapted to rise and release said valve, a port connecting said passage with said valve-chamber, and a port opening from the valve-seat to the burner.
2. An automatic cut-off for gasburners comprising a body located between the burner-cock and burner, said cut-ofl comprising a body formed with a transverse valve-chamber provided at one end with a valve-seat, avalve in said chamber and adapted to enter said seat, a spring tending to force the valve into its seat, a vertically arranged gas-passage communicating with the valve-chamber, an arm connected with said valve and extending over the upper end of the gas-passage, means for locking the said arm in its forward position, a float in said gas-passage and adapted to trip said arm, a port extending from the gas-passage below its upper end to the valve-chamber forward of the valve, and a port communicating with the valve-seat and the burner and adapted to be closed by the movement of the said valve.
3. An automatic cut-oif for gas-burners located between the gas-cock and the burner and comprising a body formed with a transverse valve-chamber, a valve-seat at one end of the chamber, a plug adapted to close the opposite end of the chamber, a spring-operated valve adapted to enter said seat, said valve formed with an outwardly projecting operating handle and with a valve-stem supported in said plug, means to prevent the turning of said valve-stem, a vertically arranged gas-supply passage opening into the valve-chamber, an arm connected with the valve and extending over said passage, means for holding said arm in its forward position, a float in said gas-passage and adapted to trip said arm, a port connecting the gassupply passage below its upper end with said chamber, and a port leading from the valve-seat to the burner, which port is adapted to be closed by the movement of said valve.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
