Coupling hose assembly
First Claim
1. A hose and clamp assembly for quick assembly of the hose with two spaced rigid tubular members, such as an automobile radiator inlet and an automobile engine outlet, said hose comprising an elastomeric material having a pair of circular clamps thereon, one adjacent each of its ends, one end of the hose being applicable to one of said tubular members and the other end of the hose being applicable to the other with the clamp on said one end of the hose surrounding said one tubular member and the clamp on the other end of the hose surrounding the other tubular member, each clamp comprising a flexible band extending circumferentially around the hose disposed in direct engagement with an elastomeric exterior surface of the hose, means on each of the band for pulling it around the hose so as to cause the band to squeeze the hose for sealing engagement of the interior surface of the hose with the respective tubular member, each band being secured to the hose by directly bonding the inner surface of the band to the elastomeric exterior surface of the hose over a limited minor area of the band and having a major portion of its length extending from said area of securement free of the hose and disposed for direct engagement with the exterior surface of the hose, each band being adapted to be pulled around the hose by the respective pulling means independently of the other band to effect squeezing of the hose within the band without imparting any squeeze to the hose within the other band, the hose being free to flex between the bands.

Abstract
A coupling hose assembly with a flexible hose and two clamps each bonded for only a minor portion of the length thereof to the hose, each positioned adjacent an end portion of the hose. Ridges are formed in the hose on each side of each clamp to guide each clamp as it is being tightened. The inside of the hose is provided with a circumferential bead against which the ends of tubular members can be positioned so that they are inserted sufficiently in the hose so as to be in proper registry with the clamps, thereby ensuring that when the clamps are tightened they will constrict the hose uniformly about the tubular members to produce seals therebetween.
