Application niei mv'em er z'oji a0; s riai are, f425j55 1' To all whom it may concern:

Be it known that we, FRANK-L. PUTNAM and Gnonon EBERSPACHER, citizens of the, United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Automatic Gas Valves, of which the following is a specification. 1

This invention relates to new and useful improvements in acombination gas and water valve.

One object of the invention is to provide a device of the character described which is specially'adapted for use in connection with gas water heaters for controlling the supply of gas to the burner and embodies a novel combination whereby gas will be automatically admitted tothe burner when the water is turned on to be admitted to the water coil of the heater.

Another object of-the invention is to provide a valve that will automatically shut off the gas when the water is turned off;

A further feature of the invention em bodies a novel construction which is not liable to become disabled or .to get out of order by reason of the fact that the working parts are protected by suitable surrounding protecting casings.

With theabove andother objects in view the invention has particular relation to certain novel'features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated inthe accompanying drawings, wherein 1 V The figure shows avertical sectional view of the device.

Referring now more particularly to the' upstanding sleeve 2 which is spaced from the walls of the casing. Fitted over this sleeve.

there is a valve 3 of the form of an inverted cup and provided with an outlet opening4.

The casing 1 is secured to the upper end of a yoke 5 and to the lower end of said yoke there is secured a'tubular gas-valve casing 6 provided with the inlet opening 7 through which gas enters from the gas inlet pipe 8. A valve rod 9 works through suitable stuffing boxes '10 and 11 provided in the lower and upper ends, respectively, of the casings 1 and 6. The upper end of this rod is atcluding'a Water valve casing and a gas valve A specification of l ateiited tached tothe valve 3 and "to the lower end thereof the valve 12 is secured. Within the casing 6 there is a strong coil spring 13 which surrounds the rod 9 and is interposed between the valve 12 and the opposite end of thecasing '6. lVater is admitted through the water inlet 14 and when the water is lifts the valve 3until the opening 4. clears the upper end of said sleeve and the water then passes through the; pipe 15"to the coil 16. matically lifted, permitting gas to pass outthroughlthe port 19, controlled thereby, in the bottom of the casing 6 and the gas then passes. to the burner 17 through the pipe 18. The gas from the burner is ignited by the usual pilot light, (not. shown).

It is obvious from the foregoing that when the water is turned on the pressure thereof will automatically open the gas valve and admit as to the burner 1 arranged underneath tile water coil and whereby said coil will be heated and whenthe water isturned off the spring 13 will cutoff the supply of gas and thusextinguish the flame.

What we claim is r 1. A device of the character described, in-

casing, the former of which has a water inlet and the latter of which has a gas outlet port,- a sleevehavingauniform exterior within the water valve casing and spaced from the wall thereof, within which the water is delivered through said water inlet,

a valve fitted' over said sleeve and at all:

cluding a pair of valve casings, a cylindrical upstanding sleeve anchored to the bottom of one casing and spaced from thewall thereof, an inverted cup-shaped valve fitted over said sleeve and forming, atall times, a tight joint therewith and provided with a side port positions forming a watertight jointtheref A with, and'provided with an outlet port, ai Which is opened by the sleeve when the valve is elevated and closed thereby when the valve is lowered, an'inlet through said vcasing into the interior of thesleeve, an outlet lead-:

ing from said casing, the other casing being provided With an outlet port, a disc valve normally closing said outlet port, a rigid valve stem to the respective ends of'which' said respective valves are attached, a resilient member within theilast mention'ed easing normally holding the valves in closed posi-
