Abstract
Abstract A device for restraining high pressure pipes from whipping, if ruptured, said device comprising a pedestal supporting a sleeve that has an inner diameter that exceeds the outer diameter of the pipe, and is loosely received over the pipe, and that is supported on the pedestal to be spaced from the pipe about its circumference; a pair of tie bands are each looped about the sleeve and tensioned against the sleeve, with the respective tie bands having their ends anchored to the pedestal on either side of the pipe to secure the sleeve against the pedestal in spaced relation about the pipe. The pedestal may be rigidly connected to the building floor, but preferably is resilient in nature in order to act as an energy absorber in resisting pipe whip.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A pipe movement restricting device comprising: a pipe, a pedestal structure, a sleeve proportioned to freely receive said pipe and be spaced from contact with same, said sleeve being supported on said pedestal in a position to be substantially concentric with said pipe, a first tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on one side of said pedestal, and a second tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on the other side of said pedestal, said tie bands being tensioned against said sleeve to press same against said pedestal and hold said sleeve in spaced relation about the pipe from divergent directions.
Claim 2
Dependent Claim
124 words
A pipe movement restricting device comprising: a pipe, a pedestal structure, a sleeve proportioned to freely receive said pipe and be spaced from contact with same, said sleeve being supported on said pedestal in a position to be substantially concentric with said pipe, a first tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on one side of said pedestal, and a second tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on the other side of said pedestal, said tie bands being tensioned against said sleeve to press same against said pedestal and hold said sleeve in spaced relation about the pipe from divergent directions.
Claim 3
Independent Claim
167 words
A device for restraining movement of a high pressure pipe in the event of rupture of same, said device comprising: a pipe, a pedestal structure disposed in upright position, under the pipe and in a plane extending transversely of the pipe, a sleeve proportioned to freely receive said pipe and be spaced from contact with same thereabout, said sleeve being received over the pipe and being supported on said pedestal in a position to be spaced from said pipe about the circumference of said sleeve, a first tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on one side of said pedestal, and a second tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on the other side of said pedestal, said tie bands being tensioned against said sleeve to press same against said pedestal and hold said sleeve in said spaced relation about the pipe from divergent directions.
Claim 4
Independent Claim
167 words
A device for restraining movement of a high pressure pipe in the event of rupture of same, said device comprising: a pipe, a pedestal structure disposed in upright position, under the pipe and in a plane extending transversely of the pipe, a sleeve proportioned to freely receive said pipe and be spaced from contact with same thereabout, said sleeve being received over the pipe and being supported on said pedestal in a position to be spaced from said pipe about the circumference of said sleeve, a first tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on one side of said pedestal, and a second tie band looped about said sleeve in the plane thereof and having its ends anchored to said pedestal on the other side of said pedestal, said tie bands being tensioned against said sleeve to press same against said pedestal and hold said sleeve in said spaced relation about the pipe from divergent directions.
Claim 5
Dependent Claim
27 words
The device set forth in claim 2 wherein said pedestal structure includes: a resilient post against which said sleeve bears under the action of said tie bands.
Claim 6
Dependent Claim
16 words
The device set forth in claim 3 wherein: said pedestal structure is resiliently restrained against movement.
Claim 7
Dependent Claim
19 words
The device set forth in claim 2 including: means for shim adjusting said sleeve relative to said pedestal structure.
Claim 8
Dependent Claim
71 words
The device set forth in claim 2 wherein: said pedestal structure comprises: an I-beam structure having diagonal side walls disposed on either side of the pipe, said side walls converging in an upward direction, said ends of the respective tie bands being respectively secured to an anchor plate adapted to engage the respective pedestal side walls, and means for releasably clamping the respective anchor plates to the respective pedestal side walls.
Claim 9
Dependent Claim
19 words
The device set forth in claim 5 wherein said clamping means includes: means for shim adjusting said anchor plates.
Claim 10
Dependent Claim
37 words
The device set forth in claim 2 wherein: said pedestal comprises a concrete body, said ends of the respective tie bands being secured to wedge type anchoring devices received in correspondingly shaped sockets formed in said pedestal.
Claim 11
Dependent Claim
35 words
The device set forth in claim 2 wherein: said pedestal comprises: a legged structure assembly, said ends of the respective tie bands being secured to legs of said assembly on either side of the pipe.
