FLUSH TANK VALVE Filed April 50, 1940 i I M mil gmc/whom Patented Oct. 21, 1941 FLUSH TANK VALVE Yervant H. Kurkjian, Hawthorne, N. J.
` Application April 30, 1940, Serial No. 332,602
l,hcl. 4-v56 4 Claims.
V'Irnis' invention relates to flush tank valves, and has for one of its objects the production of a simple and em-cient Valve which is so constructed as totightly seat upon the Valve seat, through the medium of the weight of the water within the tank acting upon the valve.
A furtherobject of this invention is the production of an efficient flush tank valve which may be economically constructed and assembled and which will' provide an efficient closure for theg Valve seat.
Other `objects and advantages of the present invention will appear throughout the following specification and claims.
In the drawing:
Figure i vis a vertical sectional view of the vaive ifn a closed or seated position and illustrating one form of my invention, a certain portion of the Valve being shown in elevation;
Figure 2 is a bottom plan View of the Valve shown in Figure 1;
Figure 3 is a side elevational View of the valve in a partly open position, a portion of the valve being shown in section;
Figure 4 is a vertical sectional View of a modified form of the invention;
Figure 5 is a side elevational View of the upper section oi the type of valve illustrated in Figure 4, a certain portion being shown in section;
Figure 6 is a side elevational view of the lower section of the type of valve shown in Figure 4, a certain portion being shown in section;
Figure 7 is a vertical sectional view of a further modied form of valve;
Figure 8 is a top plan View of the valve disc shown in Figure 7, the stem being shown in transverse section.
By referring to the drawing, it will be seen that A designates the conventional valve seat used in conjunction with toilet valves, and the like. A hollow flush valve I is adapted to fit snugly upon the valve seat A, and this hollow flush valve I0 is preferably formed of rubber or other resilient material and comprises an inverted conical portion II, the lower edge of which is provided with a reinforcing upturned bead or flange portion l2 which is spaced away from the side walls of the conical portion II, to provide a water-receiving channel, as shown. The hollow flush valve I0 is provided with an upstanding annular fiange I3 along its upper edge and a partition I4 is formed within the hollow flush Valve I0, as shown in Figure 1, preferably formed integral with the valve I0. The partition I4 is inset with respect to the outer edge I of the valve I 0 to provide a water-containing compartment I6. A stem I'I of the conventional type is threaded into vengagement with a cap I3 tted within theA depending nipple' I 9i.
The operation of the device isas follows:
The valve Ill will operate in the usual manner to rise vertically with respect to the seat A, and uncover the valve seat. The buoyancy of the Valve I0 will permit the valve II] to rise when the valve Il) is moved from the valve seat A for the purpose of moving the valve to an open position. As' the tank, of which the valve seat A forms' -a part, empties, the water will rush through the valve seat A and contact the ange or upturned bead i2 tendingto pull the inverted conical portion II of the Valve I0 to 'a iirmvrseating position upon the valve seat. The'water which will naturally fill the compartment I6 will add additional. weight to the valve also tending to force the valve down tightly' upon the valve seat However, while' the valve l Ii is' in a raised position from its seat and is immersed within the water contained in the tank, the buoyancy of the valve will tend to counteract the weight of the water within the compartment I 6. As soon as the water falls below the level of the edge I5, however, the water within the compartment I6 will tend to add additional weight to the Valve and cause the valve I0 to become more firmly seated upon the valve seat A as soon as the water within the tank is drained off through the opening provided by the valve seat A.
It should be understood that I have provided two distinct features which will tend to force the valve Il) upon its seat, one being the upturned bead or iiange I2 against which the downwardly rushing water through the valve seat A will contact tending to pull the valve III to a seating position, and the other feature being the weight of the water within the compartment Iii which will tend to iirmly force the valve II! to a seating position upon the Valve seat A.
In Figure 4, I have shown a modied form of the invention wherein the valve Illa is formed of flexible material, such as rubber and the like, and comprises an upper section 20 and a lower section 2|. The lower section 2l comprises an inverted cone-like structure having an open lower end 22 similar to that shown in Figure 1, and the lower edge of the lower section 2| is provided with an upturned bead or flange 23 similar to the flange or bead I2. The lower section 2l is provided along its upper edge with an vide an interlocking fit between the upper and lower sections 20 and 2|. A stem 26 is secured to a cap 21 carried by a nipple 28 supported by the bottom wall 29 of the upper section 20. The upper section 20 is also provided with an upstanding annular ange 30 to provide a waterreceiving compartment 3| similar t0 the compartment I6. By means of the structure just described it will be seen that the upper and lower sections 20 and 2| are separable.
In Figure '1, I have shown a further modified type of my invention, wherein-a fiexible valve 32 is illustrated, preferably formed of rubber or other resilient material, and having an inverted cone-like lower portion 32. The lower portion 32 is provided with an open lower end 33 which lower end terminates in an upturned bead or flange 34. The valve 32 is provided with an upstanding annular flange 35 and at the point of junction between the flange 35 and the inverted conical portion 32 is provided an annular channel 36, in which channel 36 is tted the edge of a stem engaging disc 31, to which disc 31 is secured the stem 38. The disc 31 may be formed of rubber or any other suitable material, and is preferably provided upon its upper and lower faces with channels 39 and 4U. The disc 31 provides a partition between the lower and upper ends of the Valve 32 and constitutes a floor for the water-containing compartment 4|, similar to the compartment I6.
It should be understood that certain detail changes in the mechanical construction may be employed without departing from the spirit of the invention so long as such changes fall within the scope of the appended claims.
Having described the invention, what I claim as new is:
l. A tank valve of the class described comprising a exible hollow body, said body having a substantially inverted cone-shaped lower portion,
the lower portion having an open lower end and' an upturned reinforcing ange formed around the open lower end and spaced from the sides of the body to provide a water-receiving channelinto which water flowing by the valve will impinge to pull the inverted cone-like portion tightly upon a valve seat.
2. A flush tank valve comprising a flexible body formed of a pair of separable sections, one section having an inwardly extending annular bead around one end thereof, and the other section having an annular channel adapted to receive the bead in interlocking engagement for firmly holding the sections together, one of the sections being formed of resilient material for facilitating the assembly of the sections and the separation of the sections.
3. A flush tank valve of the class described Y comprising a hollow body, the lower end of which comprises a substantially inverted cone, the body having an annular channel formed intermediate the ends thereof and upon the inner face of the body, and a stem-supporting disc tted within the body and inset with respect to the outer edge of the body and having its periphery fitting within the channel, the body being flexible and resilient to facilitate the placing the periphery of the disc in the channel and removal therefrom to permit replacement of the body independently of the disc, said disc constituting a floor for a compartment formed at one end of the body.
4. A flush tank valve of the class described comprising a pair of sections, one section having an annular channel, and the other section having a portion for fitting into said channel for detachably connecting the sections together, `and one of the sections being flexible for facilitating the removal and replacement of one section independently of the other section.
