Abstract
A method of assembling a connection for branched radiator coolant hose in which the hoses to be connected are adhered onto the ends of a T-shaped connector. Then a capsule of rubber is molded around the area of the connection and cured to form a unitary and integral connection.
Claims14
A hose assembly comprising:
- at least one polymeric hose having terminal end portions;
- an integral, hollow connector branched in a predetermined configuration and having radially enlarged portions defining a predetermined number of nipples so as to accommodate the number and orientation of each of said at least one polymeric hose to be connected;
- a layer of adhesive disposed between each nipple of the connector and a terminal end portion of the at least one polymeric hose, a terminal end portion of every said hose radially distended over the radially enlarged portions and fit over its respective nipple, and in contact with said adhesive;
- and
- a capsule of polymer molded onto and covering substantially all of a portion of the connector and one of said terminal end portions of each of said at least one polymeric hose including and extending axially past the maximum radially distended portion, the capsule cured and forming a cohesive, agglomerated continuous mass with said one terminal end portion of each of said at least one polymeric hose and the connector.

A hose assembly comprising:
- at least one elastomeric hose;
- an integral polymeric connector, branched in a predetermined configuration so as to accommodate the number and orientation of each of said at least one hose, every end portion of the connector that is to seal and secure one of said at least one hose having a nipple, the nipple having a radially enlarged portion that has a substantially frustoconical obverse taper, each of said every end portion having an end of one of said at least one hose radially distended and fit over the obverse taper;
- a layer of adhesive disposed between the nipple of each end portion and the inner surface of the end of each of said at least one hose;
- and
- an outer capsule of elastomer molded onto and covering substantially all of a portion of said connector which is uncovered and cured to form a cohesive, agglomerated continuous mass with the one end of every hose to seal the assembly against fluid leakage and wherein said outer capsule of elastomer is molded onto and covers substantially all of each said one hose including that portion which is fit over the obverse taper.

A method of manufacturing a hose assembly comprising:
- installing one end of each of a plurality of elastomeric hoses onto a separate branch of a branched, hollow connector having a radially enlarged portion on each branch by forcibly sliding said one end onto said separate branch and distending each end over a radially enlarged portion;
- positioning a layer of adhesive between each of said one end of a plurality of hoses and said separate branch, said layer of adhesive bonding said one end of each of said plurality of elastomeric hoses to said separate branch to which said one end is connected:
- molding a capsule of elastomer around a sufficient portion of every said one end including the radially enlarged portion and a portion of the connector uncovered by said one ends;
- and
- curing the elastomer in the capsule to form a unitary, agglomerated continuous mass so as to seal the assembly against fluid leakage.
