TANK
Application filed November This invention relates to outlet valves for fiush tanks, and its principal object is to provide an improved valve of highly flexible construction, which will effectively seal the outlet and will not lose its shape through long-contiued use.
The accompanying drawing is a vertical sectional View showing a preferred form of my invention.
In the drawing, 1 is the top or upper portion of the valve which may be of any suit able shape and construction, the form shown being concave, with a central, upwardly-projecting stem 2 in which is embedded the usual i5 metallic spud 3 for connection with the lifting rod, and a stem-base 4 which flares toward the horizontal. I prefer to make this upper portion of vulcanized, soft-rubber compound.
5 is the lower or seating portion, of convex or conoidal form, here shown as approximately hemispherical in outline although its contour might be slightly varied. This portion is also of soft-rubber construction and is integrally joined at its upper end to the outer R5 edge of the top portion 1.
I provide the lower portion with a thickened, annular, reinforcing belt 6 of the same material, which occupies an intermediate zone of said lower portion, substantially coso extensive with the ordinary seating zone of the valve. This thickened zone lies wholly below the junction of the upperand lower portions and is connected with the outer margin of the upperport-ion 1 by a thinner,
The valve is provided with a relatively wide mouth opening 8, typical of the fullmolded type of valve vulcanized between metal surfaces of which the inner one is a core adapted to be withdrawn through the opening 8 after the completed ball has been removed from the outer mold.

Serial No. 149,153.
tortion thereof of soft-rubber sary flexibility the tank outlet.
at the seating zone, but being construction, it has the necesto effect a proper sealing of The thinner zone 7 provides a greater radial flexibility in the region immediately below the outer margin of the top portion 1 and tendency of sa static pressure promoting a ti unseated by a horizontal, inw
allows for a slight spreading id margin due to the hydrowhen the tank is full, thus ght seal. WVhen the valve is n upward pull thereon, the ardly-acting component of the upward force exerted through the stem-base 4 tends to flex and the upper 6, and thus pro the valve at the thin zone 7 portion of the thickened zone gressively break the seal with a minimum exertion of force.
I claim: 1. A hollow,
buoyant tank valve comprising an upper portion, and a softrubber lower portion connected to the outer edge of said upper portion said lower portion being est diameter at portion.
the junction with said upper 2. A hollow, buoyant tank valve comprismg a soft-rubber upper portion, and a convex, soft-rubber lower portion integrally joined to said u pper portion at the outer edge of the latter, said lower portion having a thickened relnforcing belt located in an intermediate zon e thereof and a thinner wall portion above said belt, immediately below the unction of said lower portion with the upper portion.
In witness whereof I have hereunto set my hand this 9th d ay of November, 1926.
