FLUSH VALVE Filed Aug. 27, -1930 INVENTOR e, ATTORN EY Patented June 2, 193
PArsNr ermee BERT O. TILDEN, OF TRENTON, NEW JERSEY, ASSIGNOR TO B. O. T. MFG. C0., OF TREN- TON, NEW JERSEY, A CORPORATXON OF NEW JERSEY UNITED STATES y FLUSH VALVE Application filed August 27, 1930. Serial No. 478,108.
This invention relates to flush valves to be operated in connection with water closets, and the like, and has for its object to prol vide novel construction and arrangement of the ushing mechanism, wherein the flush valve, which is preferably annular, is supported entirely by, and is movable with, a reciprocable over-flow pipe, and wherein the valve float is also supported by the said 1f over-flow pipe, all of said parts being arranged concentric or having a common axis, and being guided by a float cylinder, which is disposed concentric to the over-flow pipe, the valve body, and the outlet or discharge 35 spud. A further object is to provide an over-flow pipe, which is movable and straight, instead of being stationary and formed with the usual right angle offset to carry the waste water from an eccentrically disposed pipe to the Waste opening. By this novel disposition and arrangement of the over-How pipe, the disposal of the overflow or waste water is more positive, free and rapid and obviates all danger of the flush tank over-flowing, in case the ballfloat becomes accidentally detached from the ball-cock, and besides, the arrangement whereby the over-flow discharges directly through the valve when the latter is closed, renders the operation entirely noiseless.
And a further object is to provide a combined Hush valve, valve float, float chamber and over-flow pipe, that may be assembled at the factory and shipped and installed as one part, and which is extremely simple,
strong and durable. The present ilush valve,
which may comprise a relatively thick, leather or rubber disc, and requires no particular adjustment, and but infrequent renewal,
is designed to supplant the common, frail,
hollow, rubber, spherical valves, which are prone to leakage, and to become shattered and water-logged, and in a short time rendered useless.
I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawings, in which- Q Figure l is a top plan view of the flush tank with the cover removed. Fig. 2 is' a central vertical, longitudinal section, taken substantially on line 2 2 of Fig. l, showing the valve and related parts in elevation, the valve being in the open position.l Fig. 3 is a central transverse sectional view of the iiush valve and related parts, the Valve being closed. And Fig. t is a partial elevation and partial central vertical section of the flow pipe, the loat and flush valve.
In the drawings, 2 represents a china or 60 other flush tank, whose bottom 2 vis formed With a central opening 2a Jfor flushing purposes and an opening 2b for the in-flow of the flushing water, and 2c represents the usual cover for the tank. '3 represents the fresh water supply pipe, whichis fitted with an elevated ball-cock 3', that supports a pipe 3a employed for refilling the tank, following each iushing operation. The ball-cock is controlled by the usual ball-icat 4:, which 70 connects with the cock by means of a rod 4. 5 represents the over-flow pipe, which is disposed in'axial alignment with a cagelike valve body 6, the bottom of said body comprising a threaded spud portion 6, 75 which extends through the opening 20;, and may connect with awater closet bowl, and the like. Above the spud 6', the body 6 is formed with an integral annular portion 6a, of larger diameter than the spud, and which is adapted to over-lie, like a flange, the inner bottom surface of the tank, and m represents a nut employed to clamp the body 6 to the tank bottom. The top of the ring 6a, comprises the valve seat, as 60, and 85 in practice, the plane of said seat is not over a quarter of an inch above the plane of said bot-tom, so that at each flushing of the tank, the latter is substantially emptied. This is a very desirable feature, and will be appreciated when it is understood that in the common run of flush tanks, the flush valve seats are located one inch or more above the plane of the bottoms, which prevents a relatively large volume of the water from being dis-V pensed for flushing purposes. Heretofore the depth of this unused water has usually been two inches or more, and this water has been prevented from liowing into the bowl, to refill the same and restore the usual trap,
, admission of the water to the valve seat 6c,

from all directions. 7 representsV a cylindrical float chamber, which is normally open at its` top and' bottom ends.. The bottom of the cylinder however, is preferably closed by a detached disc 7 which may rest upon an internal horizontal flange', as 67, of the. member 6d.' The disc 7" may be dispensed with and the bottom made integral with the float cylinder'. The lower end of cylinder 7 and the top end of member 6d, may be cori respondin-gly threaded for effecting a rigid but detachable connection between said parts. The said parts may be provided with complementary bayonet fastening means, as' shown at 7a, in Figs. 2 and 3L Within the chamber 7, is disposed loosely the valve float 8, which in the instant case, is rigidly mounted concentrical'ly upon the over-flow pipe 5. The float 8 is preferably of slightly less dia-meterv than the bore of r the cylinder 7 to enable the fiushing water,
when'its level is higher than the top ofthe cylinder, to gravitate past the float and lill the cylinder; The bottom`7 is formed with a centralopening 70, to receive and guide the pipe 5. This opening is preferably slightly larger' than the pipe 5, so as to enable the water in the cylinder 7 t'o drain oil' slowly in order to retard' the closing of the valve until the full volume of flushing water has passed from the bowl. In the present case, the refill tube is dispensed with, and the refilling of the bowl to lestablish the usual trap is effected by the last few quarts of water that remain in the tank after the siphon action or effective flushing work is pipe 5 and comprises a leather or other compressible ring, as 9, which faces the seat 6c,
and a ring of brass or other metal, as Qa.,
overlies and reinforces the ring 9. The rin-gs 9-9a are preferably detachably held in place by a nut 9U, which may be threaded to. the lower end of 'the overflow pipe 5. The valve 9 seats by gravity, and the seating is rendered positive. by the combined Weight of the valve 9-9a, over-flow pipe 5 and float S, and the slight looseness of' the float within the cylinder 7, as well asf the loose lit of the iiow pipe, where it passes,
through the bottom 7", insures the proper valves the raising ofA pipe 5, :fi-oat 8- and; tlreg valve 9, as one part, frorn the position shown in Fig. 3, to that shown in Fig. 2.
