Abstract
A pipe fitting including a socket having a bore and an opening communicating with the bore. Means within the bore defining a surface inclined to the axis of the bore. Movable clamping means provided to abut the inclined surface whereby to clamp a pipe upon movement of the pipe outwardly of the bore, tubular means within the bore located between the movable clamping means and the opening. The tubular means fitting over the pipe first sealing means between the pipe and the tubular means and second sealing means between the tubular means and the socket.
Claims11
A pipe fitting including a socket having a bore and an opening communicating with said bore, means within said bore defining a surface inclined to the axis of said bore, movable clamping means adapted to clamp a pipe end extending within said bore, said clamping means including a surface substantially complimentary to said inclined surface and adapted to abut said inclined surface upon movement of said pipe outwardly of said bore to compress said clamping means to increase the clamping action thereof on said pipe, tubular means within said bore located between said movable clamping means and said opening, said tubular means fitting over said pipe, first sealing means between said pipe and said tubular means, and second sealing means between said tubular means and said socket, said first and said second sealing means being located adjacent said opening, whereby to be unaffected by said compression of said clamping means.
A pipe fitting including a socket having a bore and an opening communicating with said bore, separate insert means secured within said bore defining a surface inclined to the axis of said bore, movable clamping means adapted to clamp a pipe and extending within said bore, said clamping means including a surface substantially complementary to said inclined surface of said separate insert means and adapted to abut said inclined surface upon movement of said pipe outwardly of said bore to compress said clamping means to increase the clamping action thereof on said pipe, first sealing means between said pipe and said movable clamping means, and second sealing means between said movable clamping means and said bore, said first and second sealing means being located adjacent said opening, whereby to be unaffected by compression of said clamping means.
