Abstract

An assembly for home installation replaces a metal-bodied valve in an inner tube with a vulcanized elastomeric valve so that the tube can be safely used for play, such as in a swimming pool. The assembly includes a vulcanized elastomeric cover having a diameter larger than the diameter of the flange of the elastomeric valve, with the cover having a vulcanized bond to the flange of the replacement valve. An annular disk of unvulcanized and vulcanizable material has a central opening fitting around the body of the replacement valve so that the disk underlies the inward facing surface of the valve flange. A nonvulcanizing adhesive temporarily adheres the disk to the flange, and an unvulcanized and vulcanizable material is provided under the cover radially outward from the flange. Release material overlies the unvulcanized material under the flange and the cover, and after the release material is stripped away, the assembly is bondable to the inner tube by vulcanizing the vulcanizable material to bond the flange, disk, cover, and inner tube all together.

Dependent claims

An assembly including a vulcanized elastomeric valve having a body with a flange for replacing a metal-bodied valve in a vulcanized elastomeric article, said assembly comprising:

a. a vulcanized elastomeric cover having a diameter larger than the diameter of said flange;
b. means forming a vulcanized bond between a radially inner portion of said cover and the outward facing surface of said flange;
c. an annular disk of unvulcanized and vulcanizable material having a central opening encircling said body with said disk underlying the inward facing surface of said flange;
d. a nonvulcanizing adhesive temporarily adhering said disk to said flange;
e. means providing unvulcanized and vulcanizable material adjacent the inward facing surface of said cover radially outward from said flange;
f. release material overlying the inward facing surface of said unvulcanized and vulcanizable material under said flange and said cover;
and
g. after removal of said release material, said assembly being bondable to said article by vulcanizing said vulcanizable material to bond said flange, disk, cover, and article all together in a secure, vulcanized bond.
