Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A releasable coupling device for a pipe, said coupling comprising a body having first, second, third and fourth concentric bores, a collar retained in said first bore and having an inner surface inclined to the axis of the bores, a clamping member disposed about a pipe and within the collar for axial movement relative thereto, said clamping member comprising a plurality of flexible jaws and means cooperating with the inclinded surface of the collar for driving the jaws inwardly to clamp the pipe upon relative movement between the collar and clamping member, means in the second bore for forming a seal between the outer surface of the pipe and the wall of the second bore, said pipe being disposed in the first, second and third bores, and means fixed to the collar for guiding the pipe into the coupling having an abutment member for the end of the clamp.
Claim 2
Dependent Claim
149 words
A releasable coupling device for a pipe, said coupling comprising a body having first, second, third and fourth concentric bores, a collar retained in said first bore and having an inner surface inclined to the axis of the bores, a clamping member disposed about a pipe and within the collar for axial movement relative thereto, said clamping member comprising a plurality of flexible jaws and means cooperating with the inclinded surface of the collar for driving the jaws inwardly to clamp the pipe upon relative movement between the collar and clamping member, means in the second bore for forming a seal between the outer surface of the pipe and the wall of the second bore, said pipe being disposed in the first, second and third bores, and means fixed to the collar for guiding the pipe into the coupling having an abutment member for the end of the clamp.
Claim 3
Dependent Claim
39 words
A connector according to claim 1, in which the collar includes an annular rib constituting said guiding means which extends beyond the body member for guiding the pipe, said rib including an annular member which constitutes said abutment surface.
Claim 4
Dependent Claim
34 words
A connector according to claim 2, in which the rib and a portion of the collar include means defining a recess adapted to receive a release tool for releasing a pipe from the clamp.
Claim 5
Dependent Claim
26 words
A connector acccording to claim 2, which includes means defining a slot adapted to receive laterally a release tool for releasing a pipe from the clamp.
Claim 6
Dependent Claim
30 words
A connector according to claim 1, which includes means defining a bore in the collar portion to allow access of a release tool for releasing a pipe from the clamp.
Claim 7
Dependent Claim
40 words
A connector according to claim 1, which includes a member which surrounds any portion of the collar and clamp extending beyond the body member, said member including tubular portion for guiding a pipe and an annular surfaced constituting said abutment.
Claim 8
Dependent Claim
31 words
A connector according to claim 1, which includes a nut attached to the ring, said nut including an abutment surface for the clamp and a guide surface for guiding the pipe.
Claim 9
Dependent Claim
31 words
The coupling of claim 1 wherein said means for guiding the pipe has means for access through the collar to the clamp for release thereof from its engagement with the pipe.
