T. V. GOONY. VALVE.

No. 557,975. Patented Apr. 7, 1896 INVENTOH BY W M A TTOHNE Y S.

WITNESSES:

the supply. In swinging downward the end F moves away from the lower end of the stem G to permit the drip-valve G to again seat itself on the seat E so that the water under pressure in the upper end of the cylinder A acts on the piston E to finally seat the valve E and securely hold the same to its seat.

It will be seen that the piston E in its downward movement, by the action of the floatlever F, uncovers the port a just previous to the final seating of the valve E, so that the lever F moves the valve in a downward direction unaided by water-pressure from above until the valve is nearly seated, after which the pressure from the supply in the upper end of the cylinder A acts on the piston E to quickly seat the valve.

As the chamber or cylinder in the upper part of the valve-casing is enlarged and as the upper or piston portion of the valve is of greater diameter than the lower portion, it will readily be seen that when the port a is opened the pressure upon the upper surface of the valve will exceed the pressure upon the lower surface and the valve will be quickly forced to its seat. \Vhen the valve is thus seated, the excess of pressure upon its upper surface will hold the valve firmly toits seat and it will not be altected by any fluttering of the water in the tank which might cause the float to bob.

It will be seen that by the construction described the valve is rendered perfectly noiseless in opening and closing, and as the outlets for the water are submerged in the water contained in the tank 0 the usual noise so frequently observed in supply-valves as previously constructed is entirely obviated.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A supply-valve, comprising a valve body or casing formed with a valve-seat and a cylinder, a valve proper adapted to be seated on the said valve-seat and provided with a piston portion engaging the said cylinder, a floatlever extending into an opening in the valve proper and adapted to engage directly with the upper and lower walls of the said openin g, a drip-valve held on the valve proper and havinga stem extending into the path of the float-lever, the cylinder portion of the valve being provided with a port adapted to be opened and closed by the piston portion of the valve, the said port connecting the upper end of the cylinder with a channel leading to the supply, the free end of the said float-lever fitting loosely in the opening in the valve proper, whereby when the pressure is removed from above the valve, the said valve will have free upward movement, as and for the purpose set forth.

2. A supply-valve, comprisinga valve body or casing formed with an upwardly-projecting valve-seat and having a recess at the sides of the valve-seat communicating with outlet-openings extending through the sides of the casing, the said valve body or easing having an enlarged chamber or cylinder at its upper end, and communicating at its lower end with the water-supply, a valve proper adapted to be seated on the said valveseat and provided with an enlarged portion or piston fitted to move in the said enlarged chamber or cylinder, the said valve proper being formed with an opening, a float-lever extending into the said opening in the valve and adapted to engage directly with the upper and lower walls of the said opening to move the said valve in opposite directions, the end of the float-lever fitting loosely in the said opening, whereby the said valve has movement independent of the movement of the lever, a drip-valve fitting a seat on the said piston portion of the valve and having a stem extending through a bore in the piston and projecting into the opening in the valve in line with the end of the float-lever, the cylinder or enlarged portion of the easing being provided with a port adapted to be opened and closed by the piston portion of the valve and connecting the upper end of the cylinder with a channel leading to the supply below the valve-seat, whereby when the said port is closed and the pressure is removed from above the valve, the valve will be forced open to its full extent,-and when the said port is opened, the pressure above the valve will exceed the pressure below the valve and the valve will be quickly forced to its seat and firmly held thereon, as and for the purpose set forth.
