Abstract
Abstract A hose rotation restrainer which attaches to the inner product hose of a coaxial vapor recovery hose assembly along with the inlet end of a suction tube in the vapor passageway between the inner product hose and the outer hose to prevent rotation of the product hose in order to maintain the end of the suction tube at a low point in the catenary of the hose assembly for removing liquid accumulations.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
In a coaxial vapor recovery hose assembly having an inner product hose having an outer radius and an outer diameter, an outer hose coaxially surrounding said product hose and defining therewith an annular vapor passageway therebetween and a suction tube which extends to a low point of a catenary of the hose assembly where a liquid would accumulate while in use, a cradle-shaped hose rotation restrainer, attached to said product hose at said low point and comprising a pair of arcuate, parallel members connected at each end thereof by semicircular loops having a radius equal to the outer radius of the product hose, said members being spaced apart a distance equal to the outer diameter of the product hose.
Claim 2
Dependent Claim
119 words
In a coaxial vapor recovery hose assembly having an inner product hose having an outer radius and an outer diameter, an outer hose coaxially surrounding said product hose and defining therewith an annular vapor passageway therebetween and a suction tube which extends to a low point of a catenary of the hose assembly where a liquid would accumulate while in use, a cradle-shaped hose rotation restrainer, attached to said product hose at said low point and comprising a pair of arcuate, parallel members connected at each end thereof by semicircular loops having a radius equal to the outer radius of the product hose, said members being spaced apart a distance equal to the outer diameter of the product hose.
Claim 3
Dependent Claim
20 words
The restrainer according to claim 1 wherein said members and said loops are formed from a continuous piece of material.
Claim 4
Dependent Claim
48 words
The restrainer according to claim 1 wherein it is formed of a material which is rigid enough to retain the arcuate shape of the restrainer when no tension is exerted on the hose assembly, yet flexible enough to straighten out when tension is exerted on the hose assembly.
Claim 5
Dependent Claim
147 words
A coaxial vapor recovery hose assembly comprising an inner product hose having an outer radius and an outer diameter; an outer hose coaxially surrounding said product hose and defining therewith an annular vapor passageway therebetween; a suction tube located within said passageway and connected at one end to a suction means, the other end thereof being located at a low point of a catenary of said hose assembly where a liquid would accumulate while in use; a cradle-shaped hose rotation restrainer attached to said product hose at said low point and comprising a pair of arcuate, parallel members connected at each end thereof by a semicircular loop having a radius equal to said product hose radius, said members being spaced apart a distance equal to said product hose diameter; and means for attaching said restrainer and said suction tube to said low point of the product hose.
Claim 6
Dependent Claim
147 words
A coaxial vapor recovery hose assembly comprising an inner product hose having an outer radius and an outer diameter; an outer hose coaxially surrounding said product hose and defining therewith an annular vapor passageway therebetween; a suction tube located within said passageway and connected at one end to a suction means, the other end thereof being located at a low point of a catenary of said hose assembly where a liquid would accumulate while in use; a cradle-shaped hose rotation restrainer attached to said product hose at said low point and comprising a pair of arcuate, parallel members connected at each end thereof by a semicircular loop having a radius equal to said product hose radius, said members being spaced apart a distance equal to said product hose diameter; and means for attaching said restrainer and said suction tube to said low point of the product hose.
