FLOAT-VALVE.
Specification of Letters Patent.
Application filed April 6, 1912.
Patented June 10, 1913.
Serial No. 688,939.
To all whom it may concern Be it known that I, FRANK SCHUH, a citizen of'the United States, and a resident of Albany, in the county of Albany and State of New York, have invented a new and Improved Float-Valve, of which the following is a full, clear, and exact description.
The invention relates to flushing tanks for supplying water to water closets, urinals and other similar fixtures, and its object is to provide a new and improved float-controlled inlet valve, arranged to insure a proper opening and closing of the valve against the pressure of the water supply to direct the incoming water in a downward direction, to prevent upward squirting of the water, at the same time rendering the valve practically noiseless to render the valve self-cleaning of sediment and other extraneous matter, and to prevent the valve from sticking.
For the purpose mentioned use is made of a valve, levers extending in opposite directions and controlling the valve, and a float connected with the ends of the levers.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in
which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a perspective view of a floatvalve as applied to a flushing tank, part of the latter being broken out; Fig. 2 is an enlarged sectional side elevation of the valve as applied to the bottom of the tank; Fig. 3 is a cross section of the valve seat; Fig. 4: is a side elevation of the valve; Fig. 5 is an enlarged side elevation of one end of the float and its connection with the corresponding valve lever; and Fig. 6 is an end.
body B in position on the bottom Av and.
to properly connect the su l iae G with the body B. pp y p 1 In the body B rises centrally a valve seat B adapted to be engaged at its upper end by a washer F held on the under side of the top of a bell-shaped valve G extending within the cup-shaped body B, as plainly indicated in Fig. 2. The valve G is preferably provided in its side wall with openings G for the passage of the water, it being understood that when the valve G is raised it opens the valve seat B and allows water to pass through the seat B against the under side of the bell-shaped valve G- which directs the water in a downward direction against the bottom of the body B to then rise in the latter and pass into the tank A to fill the same to the usual normal level.
It will be noticed that when the valve G is in an open position and the water is directed in a downward direction by the valve G it prevents the water from squirting upward in the tank and practically renders the ball cock noiseless and at the same time any sediment that may settle in the bottom of the body B is washed out of the same by the force of the incoming water.
The top of the bell-shaped valve G is provided with an integral apertured boss G into which extend the inner ends H and H of float-controlled levers H and H pivoted at I and I on lugs B rising integrally from the upper edge of the cup-shaped body B. The levers H and H are provided with upwardly-extending. arms H, H terminating in threaded ends H H on which screw nuts J, J engaging brackets K and K attached to the ends of a float L, made in cylindrical or other shape, and extending loosely between the arms H and H of the operating levers for the valve G. Each of the brackets K and K is formed of two spaced members between which the corre sponding threaded end H or H extends, and each member has a horizontal top K and an upwardly and outwardly inclined bottom K and the nut J or J is between the said top K and the bottom K When the water is discharged from the tank A then the float L falls with the water and in doing'so the tops K of the brackets .K and K bear on the upper surfaces of the nuts J, J to impart a swinging motion to i the levers H and H so that the valve G is lifted in a vertical direction to open the valve seat 13 and thus allow water to pass into the tank A to till the same to the normal level. As the water rises in. the tank A to the normal level the float L rises with it and consequently the inclined bottoms K of the brackets K and K bear on the under sides of the nuts J and J thus imparting a swinging motion to the levers H and ii in a reverse direction so that the lovers move the valve G in a downward direction until the valve is finally seated on the valve seat B and closes the same.
In order to insure a proper contact of the nuts J, J with the tops K and the bottoms K of the brackets K, K the upper and lower surfaces of the said nuts are preferably rounded off or made spherical, as plainly indicated in Figs. 5 and 6.
The bell-shaped valve G is loosely fitted in the body B to permit ready escape of the water into the tank, and in order to prevent sidewise motion of the valve G at the upper end {thereof use is made of a screw G screwing in the top of the boss G to extend in close proximity to the inner segmental end faces of the ends H H (see Fig. 2).
From the foregoing it will be seen that by the arrangement described the float L and the valve G move vertically up and down and consequently the valve is not liable to stick, and a proper opening and closing of the valve is insured.
The tank A is provided with the usual outlet valve N under the control of the operator and connected with a flushing pipe 0 leading to a water closet, urinal or other fixture to be flushed. A refilling pipe P connects with one side of the valve body 13 to allow refilling in case any of the fixtures of the tank are out of order, the pipe also serving as an overflow pipe to carry oil surplus water.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:
1. A float valve for flushing tanks and the like, comprising a cup-shaped body having a valve seat rising centrally in the body for the passage of the water into the tank, a bell-shaped valve extending into the said body and surrounding the said valve seat, the under side of the said valve being adapted to be seated on the upper end of the said valve seat, levers extending in opposite directions and fulcrumed on the said bod the said levers being connected with the top of the said valve and the levers having upwardly-extending arms terminating in threaded ends provided with nuts, and a float provided at its ends with brackets engaging the said nuts.
2.
