Abstract
Abstract A hose coupler wherein the end of a hose member is slit longitudinally in a plurality of locations in order to permit it to be flared over a frusto-conical surface of a male coupling member. The latter is also provided with a roughened exterior surface in order to help prevent the slit end of the hose member from slipping off the frusto-conical surface. The male coupler member is provided with a substantially cylindrical surface region wherein a watertight seal is effected between the flexible hose member and the coupler. A female coupling member is provided with a frusto-conical inner surface so that it may be placed in telescoping relationship with respect to the slit end flexible hose and pulled toward the frusto-conical external surface on the male coupling member to establish a wedge fit therewith. In this manner it is possible to effect a watertight seal at one point and pull the assembly at another point whereby a leak does not develop if the end pull causes physical damage to the inner tube portion of the hose in the area of the hose where pull is effected.

Claim 1
Independent Claim
258 words
In a watertight coupling for a flexible hose capable of imparting high tensile end pull substantially uniformly to said flexible hose, the combination which comprises: a. a male coupler member, b. said male coupler member being provided with a substantially frusto-conical external surface portion to receive the end of a flexible hose member over at least a portion of said frustoconical external surface portion, 1. said male coupler member further being provided with a shoulder at its leading end and a groove inboard of said shoulder, c. a female coupler member having a frusto-conical inner surface which overlies said frusto-conical surface of said male coupler member and engages the end of said flexible hose member substantially uniformly around the external periphery thereof, d. said frusto-conical surfaces being wedged together but spaced apart through the intermediary of said flexible hose member, e. and means separate from said female coupler member for engaging said flexible hose member to establish a watertight seal between said male coupler member and said flexible hose member, 1. said means for engaging said flexible hose member to establish a watertight seal comprises a clamping member in registry with said groove and retained therein by said shoulder with said hose member being intermediate said clamping member and said groove, f. said frusto-conical surfaces of said male and female couplers being wedged together outboard of the locus of said watertight seal whereby damage to said flexible hose member resulting from said wedging action of said coupler members will not cause a leak in said flexible hose member.
