To aZZ whom may concern Dim-1L,

3c i' known that 1, CHARLES a citzen of the United States of America,

residing at Jackson, in the county of Jackson and State oiE'h lichigun, have invented certain new and. useful Improvements in Automatic GusValvee; and I do her oy cleclare the following to be a full, clear, and

exact description of the invention, such as it appertains to make and use the some.

My invention relates to improvements in automatic valves and more pa ticularly to the type aduptecl to he used on sutonmtic Wutn? l'zezrters and the like, and its object is to provide the device will] miltoi'natic mechanism which will enable the valve to return quickly to closed position as soon as the water pressure is turned oil and to pro- Vlde the same with various other new and useful features hereinafter more fully rlescribed and particularly pointerl out in the claims.

In illustrating my improved clevici-i l have shown an ordinary form of gas valve which ll herein describe for the purpose more clearly bringing out the nature of my in vention, reference being had to the accompanying drawing, in which:

After the water has been turned off and the pressure released the disk 15 will be raised by the springs 16 opening the pas sage 13 and allowing the Water which remains above the piston to pass freely therethrough thus permitting the gas valve to be returned quickly to closed position by means of the spring 5. It will be noted that after the water is shut off there remains a slight excess of pressure above the piston due to the opposite pressure of the spring 5. The spring 16 will open the valve 15 against this pressure however, but will yield to the impact of water on-the valve when the same is flowing through the motor.

What I claim is f 1. In combination with a gas controlling valve; a cylinder having an inlet at the top and an outlet near the bottom, a piston movable in the cylinder and connected to the valve to control the same, a spring yieldably supporting the piston and closing the valve,

said piston alsohaving a vent.opening therethrough, a vent valve above the piston and opposlte the inlet opening of the cylinder, and a spring supporting the vent valve above the piston in the open position, and yielding to permit the valve to be closed by impact of the current of fluid flowing through the cylinder.

2. The combinationwith an automatic gas valve having a motor provided with a piston, of an automatic water release, com rising a guide pin projecting from one si e of the piston, a series of passages through the piston grouped about the guide pin, a disk slidably mounted upon the guide pin, springs to normally space the disk away from he passages, said disk being adapted to In ve downward by impact of fluid passing through the motor to close the passages substantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.
