Method of constructing a hose

Claim 1

The method of constructing a hose comprising in sequence as a continuous process the steps of extruding a core tube of synthetic rubber over a mandrel whereby the mandrel will control the inside diameter of the core tube throughout the remainder of the process, completely curing the core tube by application of heat to the core tube and mandrel, applying a bonding agent to the tube after the tube is completely cured, and applying a reinforcement over the tube in a manner to effect a bond of the core tube to the reinforcement via the bonding agent and whereby neither the bonding agent nor the reinforcement is subjected to said heat.

Claim 2

The method of constructing a hose comprising in sequence as a continuous process the steps of extruding a core tube of synthetic rubber over a mandrel whereby the mandrel will control the inside diameter of the core tube throughout the remainder of the process, completely curing the core tube by application of heat to the core tube and mandrel, applying a bonding agent to the tube after the tube is completely cured, and applying a reinforcement over the tube in a manner to effect a bond of the core tube to the reinforcement via the bonding agent and whereby neither the bonding agent nor the reinforcement is subjected to said heat.

Claim 3

The method of constructing a hose comprising in sequence as a continuous process the steps of extruding a core tube of synthetic rubber over a mandrel whereby the mandrel will control the inside diameter of the core tube throughout the remainder of the process, completely curing the tube by application of heat to the tube and mandrel, applying a first coating of bonding agent to the exterior of the tube after the tube is completely cured, applying a first reinforcement layer of cotton braid over the tube to be adhered thereto by said bonding agent, applying a second reinforcement layer comprising stainless steel braid over the first layer, applying a second coating of bonding agent to the second layer so as to penetrate the interstices thereof to make contact with the first layer, and applying an upper layer of cotton braid over the second layer into contact with said second coating whereby the coatings bond the three layers together and said heat is not applied to the bonding agents or reinforcement.

Claim 4

The method of constructing a hose comprising in sequence as a continuous process the steps of extruding a core tube of synthetic rubber over a mandrel whereby the mandrel will control the inside diameter of the core tube throughout the remainder of the process, completely curing the tube by application of heat to the tube and mandrel, applying a first coating of bonding agent to the exterior of the tube after the tube is completely cured, applying a first reinforcement layer of cotton braid over the tube to be adhered thereto by said bonding agent, applying a second reinforcement layer comprising stainless steel braid over the first layer, applying a second coating of bonding agent to the second layer so as to penetrate the interstices thereof to make contact with the first layer, and applying an upper layer of cotton braid over the second layer into contact with said second coating whereby the coatings bond the three layers together and said heat is not applied to the bonding agents or reinforcement.
