FLUSHlNG-TANK.
SPECIFICATION forming part of Letters Patent No. 630,586, dated August 8, 1899.
Application filed August 11, 1897. Serial 71 (N0 modem To all whom it may concern:
Be it known thatI, DAVID D. BUICK, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Flushing-Tanks, of which the following is a specification,reference being had therein to the accompanying drawings.
This invention consists in the peculiar construction of the combined discharge-valve and overflow, and, further, in the peculiar construction, arrangement, and combination of parts, as more full y hereinafter described and claimed.
In the drawings, Figure 1 is a vertical 1ongitudinal section through my improved flushing-tank. Fig. 2 is an enlarged view ofthe discharge-valve and overflow. in a different.-
position. Fig. 3 is a perspective view of the fulcrum-bracket.
A is the tank proper, which may be of any suitable construction.
B is the inlet-valve, and O the float con-;
trolling the operation of said valve.
D is the discharge-pipe, and E is the seat for the valve F, controlling said discharge, which valve is constructed as follows:
a is a hollow sphere, preferably of sheet metal andin two sections. The lower section is formed with a central opening, around which is the outwardly-spun flange b, which forms a seat for the valve-ring 0, formed of rubber or other suitable material and adapted to bear upon the valve-seat E.
dis a tube passing through the sphere a, being secured to the upper section, preferably by soldering, and extending up to the normal height of the water in the tank when the valve is seated.
G is a rod passing centrally through the tube (Z and secured at its lower end to a spider e in the valve-seat E, preferably by means of the nuts f and g engaging withthe screw-threaded end of said rod above and below the spider e.
H is a cone secured to the upper end of the rod G a short distance above the upper end of the overflow-pipe (1 when the valve F is resting upon its seat.
I is a flange or collar at the upper end of the pipe d, and J is a lever having the bifureated end embracing the pipe (1 below the col lar I. This leveris fulcrumed in the bracket K, secured to one side of the tank, and comprises the plate h, secured to the outer side of the tank-casing, having a slot 01, through which the lever J passes, and the inwardly extending bifurcated arm j, between the bifurcations of which the lever J is pivoially secured.
K is the pull cord or chain, attached to the outer end of the lever J.
L is a cover to the tank.
The parts being thus constructed as shown and described, the operation is as follows: When the valve F is resting upon its seat E, if water be admitted to the tank through the valve B it will rise to the level of the upper end of the pipe d, at which point the raising of the float C will close the valve B. Should, however, the valve fail to close for any reason, the water cannot rise higher, as it will overflow through the pipe d and be discharged in the discharge-pipe D. As the water rises in the tank the valve F is held to its seat by reason of the exposed area of the upper side of'the sphere a being greater than that of the lower side thereof. The lever J is normally held with its bifurcated end just below the collar I, as shown in Fig. l of the drawings, theouter end of said'lever resting against the shoulder is, formed at the upper end of the SlOlH; in the bracket K. When the cord or chain'K is pulled, the inner end of the lever J will be raised, lifting the valve F from its seat E and allowing it to rise by its own buoyancy until the upper end of the overflowpipe is seated against the cone H. This will close the overflow pipe, while the hollow sphere a will act as a float to hold the valve F in its raised position even after the lever J is dropped. Thus while the water is discharged from the tank the overflow-pipe is sealed. When the water is completely discharged from the tank, the valve will again is obtained by formiu g the retaining flange or seat I) for the valve-ring c as an integral part of the sphere a, spun out of sheet metal. With previous constructions it has been cus- Too tomary to employ a cast ring to form the seat, soldered or otherwise secured to the sphere; but this increases the weight and necessitates a large sphere to obtain the required buoyancy, thus displacing a larger quantity of water. A f n rther advantage of my construction is that the sealing of the overflow-pipe when the valve is opened prevents the drawing of air in with the water and the noise occasioned thereby.
That I claim as my invention is The combination with the tank, the valve controlling the discharge-opening therein and the lifting-leverforsaid valve, of the fulcrum-
