VALVE.

Application led February'21, 1922. Serial No. 538,273.

To all whom t lmay concern Be it known that I, THOMAS O. MOUNTAIN, a citizen of the United States, residing at El Paso, in the county of El Paso and, State of Texas, have invented new and usefulImprovements in Valves, of which the following is a specification.

The object of this invention is to provide means for preventing a tank or container from overflowing, when being filled through a hose or the like.

Another object of the invention is to make.

such means automatic so that as soon as the liquid reaches a point adjacent the top of ose or other Afilling medium will be stopped.

This invent-ion also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters 'denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevation of the invention.

F igure-2 is a longitudinal sectional view thereof showing the parts thereof in inoperative position.`

Figure 3 is a similar view showing the parts in operative position.

lfigure 4 is a view showing the invention applied to a .gasoline delivery pump.

Fi re 5' is a view showing the invention applied to another kind of pump.

The remaining figures are detail views.

In these views 1 indicates a faucet which is adapted to be connected with a hose 2 or the like which delivers the liquid from the source of su ply to the passage -3 of the faucet. A va ve 5 controls the flow of liquid through this passage, said valve being adapted to engage a seat 6, which separates one part of the passage from another part, when the valve is in closedposition and 4said valve is adapted to engage a recess 7 `when in open position, said recess being below the level of the passage sothat the valve will not interfere with the flow of liquid. I may make the bottom of this recess removable, as shown at 8, so as to facili tate assembling of the parts. A cylinder 9 liquid from the passage into the cylinder. v

A piston 12 is located in the cylinder and this piston is secured to the valve stem, as shown. The valve stem passes through a hole in the top of the cylinder and the lower end of the. cylinder is provided with an opening 13 which communicates with the atmosphere. A jacket 14 is formed around the outlet portion of the faucet and the space formed Vby this jacket is in communication with the cylinder through the port 15. A passage 16 has one end connected with the upper end of the cylinder and its other end is adapted to be connected to a pipe or tube 17 which leads toa suction creating part hereinafter referred to.

The drawings show the inventionY applied to gasoline delivering pumps of the two different types, though it will of course be understood that the invention can be used in filling containers of all kinds. n

Referring to Figure 4 the outlet of the pump 18 is connected by the hose 19 with my improved faucet so that the gasoline flowing from the pumps will pass through the hose into the faucet and from the faucet into-the tank of the motor vehicle. The piston of the pumpg 18 is provided with the usual rack 20 which is engaged by 4the toothed wheel 21 connected with the handle 22. A small cylinder 23 is supported by the -pump and the lpiston 24 of the cylinder.l is connected with t e rack so that the piston will move when the pump is being-actuated. The bottom ofthe cylinder 23 is connected by the tube 17' with' the paage 16 so that as the pump is actuated air will be drawn through the jacket space, into Icylinder 9,' through passage 16 and tubing 17 f into the lower partuof the cylinder 23. vAs the valve 5 is in open position the piston 12 will be below the port 15 and will not interfere with A valve 5 upon its seat thus stopping the flow of liquid through the faucet. The resulting back pressure in the pump holes will prevent further movement of the pump parts so that the operator will know that-the tank is full and thus prevent overflowing of the tank. The hose and faucet can be drained by pushing downwardly upon the valve stem, which projects above the top of the cylinder, so as to force the valve from its seat.

Figure 5 shows the device applied to a visible form of pump in which a bottle is used to receive the liquid pumped out of the supply tank. After the proper amount of liquid has been pumped into the bottle a valve 26 is` opened to permit the liquid in the bottle to flow through the holes into the tank of the vehicle. ln this case l connect the tubing 17 with the top of the bottle so that the dow of liquid therefrom will create a suction in the cylinder and as soon as the How of air is cut off by the liquid reaching the -end of the jacket 'space this suction will cause the piston in cylinder 9 to raise thus closing the valve 5 and preventing the liquid from passing into the tank. The operator must .then close valve 26.

It will thus be seen that the device will work automatically to prevent overflowing of tanks or other containers. Any suitable form of suction means may be connected with the cylinder for movin the valve to closed osition when the tan or container is fille i It is thought from the foregoingl description that the advantages and novel features invention will be readily apparent.

of may I esire it to be understood' that ll may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What l claim is l. A faucet of the class described comprising a normally opened valve, a suction chamber connected with ther faucet and. through which. the valve' stem passes, a piston in said chamber connected with the stem, a connection from the chamber to a point adjacent the outlet end of the faucet l:3nd means for drawing air from the charn- 2. A device Aof the class described comprising a' body having a passage therethrough, means for connecting one end of said passage to a source of liquid supply, a valve for controlling said passage, a cylinder forming part of the body and through which the valve stem passes, a piston in the cylinder connected to the valve stem, a passage leading from said cylinder to a point adjacent the outlet end of the passage and means for drawing air from the upper end. of the cylinder.

3. ln combination with a vgasoline pump, a faucet connected with the hose thereof, a normally opened valve in the faucet, a cylinder forming part of the faucet and through which the valve stem passes, a piston in the cylinder connected with the stem, a passage leading from the lower part of the cylinder to a point adjacent the outlet end of the faucet and means associated with thel pump for drawing air from the top of the cylinder.

ln testimon whereof I aflix 1n signature..
