Abstract
Abstract A rapidly assembled and disassembled, pressure tight connection of a firehose to a hydrant or the like is made even if the threads of the outlet pipe of the latter are damaged or do not exist. A slotted, clamping sleeve receives a clamping nut on its external threads, and when the nut is tightened the slotted end of the clamping sleeve engages the outlet pipe. A hose connector carries an enlarged external diameter collar faced with a gasket which bears against the end of the outlet pipe and the gasket is forced thereagainst by a threaded body which engages internal threads on the clamping sleeve. The hose connector swivels inside the body until the collar is tightened against the end of the outlet pipe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A connector comprising a cylindrical body having a first end formed for attachment to a hose or other outlet and a second end opposite said first end, a seal on said second end having an external diameter larger than said second end, a sleeve surrounding said second end and rotatable relative thereto prior to completion of connection, said sleeve bearing against said seal and having external first threads, and means preventing said sleeve from being detached from said second end, an annular connector member having internal second threads mating with said first threads and having a plurality of axially projecting tapered fingers separated from each other by radial slots, said fingers surrounding said seal and projecting beyond said seal and being deformable in a radial direction relative to said connector member, said fingers formed with external third threads, and a nut surrounding said fingers and having internal threads in threaded engagement with said third threads, whereby upon rotation of said nut relative to said connector member said fingers are clamped against a tubular outlet disposed within said fingers and upon rotation of said sleeve relative to said connector member said seal is tightened against said outlet and said body is gripped against rotation relative to said connector member.
Claim 2
Dependent Claim
208 words
A connector comprising a cylindrical body having a first end formed for attachment to a hose or other outlet and a second end opposite said first end, a seal on said second end having an external diameter larger than said second end, a sleeve surrounding said second end and rotatable relative thereto prior to completion of connection, said sleeve bearing against said seal and having external first threads, and means preventing said sleeve from being detached from said second end, an annular connector member having internal second threads mating with said first threads and having a plurality of axially projecting tapered fingers separated from each other by radial slots, said fingers surrounding said seal and projecting beyond said seal and being deformable in a radial direction relative to said connector member, said fingers formed with external third threads, and a nut surrounding said fingers and having internal threads in threaded engagement with said third threads, whereby upon rotation of said nut relative to said connector member said fingers are clamped against a tubular outlet disposed within said fingers and upon rotation of said sleeve relative to said connector member said seal is tightened against said outlet and said body is gripped against rotation relative to said connector member.
Claim 3
Dependent Claim
23 words
A connector according to claim 1 in which said seal includes a rigid collar of an external diameter greater than said second end.
Claim 4
Dependent Claim
36 words
A connector according to claim 2 in which said collar is fixed to said second end of said body and said seal comprises a resilient gasket on the side of said collar opposite said second end.
Claim 5
Dependent Claim
29 words
A connector according to claim 1 which further comprises separate turning means connected to said body, said sleeve and said nut for turning movement thereof relative to each other.
Claim 6
Dependent Claim
16 words
A connector according to claim 4 in which each said turning means comprises a radial handle.
Claim 7
Dependent Claim
