Abstract
Abstract A pipe support comprises a pipe shoe, an upper stainless steel bearing member curved upwardly at opposed edges to provide vertical stainless steel returns, and a lower bearing member having a bearing surface of low-friction material surmounting a layer of elastomeric material. The pipe shoe is advantageously of U-shape, W-shape or inverted Tee-shape and has a serrated or toothed upper periphery capable of being tailored prior to use by removal of the tips of the teeth to suit the specific geometry of pipe diameter and desired bottom-of-pipe to top-of-steel dimensions. A method of manufacturing U-shaped and inverted Tee-shaped serrated or toothed shoes in pairs is also provided, which involves cutting a rectangular tube longitudinally along two opposite sides or cutting a structural steel I- or H-section longitudinally thereof with a zigzag line of cut, whereby to form two similar serrated-edged halves.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A pipe support comprising a. a pipe shoe for connection to a pipe; b. an upper bearing member connected to the pipe shoe to support the same, said member having a horizontal portion that curves upwardly at a pair of opposite edges into a pair of upwardly extending returns, said horizontal portion having a downwardly facing, flat, smooth, horizontal bearing surface fixedly secured thereto; and c. a lower bearing member beneath the upper bearing member having an upwardly facing, low-friction bearing surface secured to and surmounting a layer of elastomeric material that in turn is secured to and surmounts a base plate for mounting the lower bearing member in a fixed location; d. said bearing surfaces directly engaging each other in free sliding relationship in any direction in a horizontal plane defined by said surfaces.
Claim 2
Dependent Claim
135 words
A pipe support comprising a. a pipe shoe for connection to a pipe; b. an upper bearing member connected to the pipe shoe to support the same, said member having a horizontal portion that curves upwardly at a pair of opposite edges into a pair of upwardly extending returns, said horizontal portion having a downwardly facing, flat, smooth, horizontal bearing surface fixedly secured thereto; and c. a lower bearing member beneath the upper bearing member having an upwardly facing, low-friction bearing surface secured to and surmounting a layer of elastomeric material that in turn is secured to and surmounts a base plate for mounting the lower bearing member in a fixed location; d. said bearing surfaces directly engaging each other in free sliding relationship in any direction in a horizontal plane defined by said surfaces.
Claim 3
Dependent Claim
173 words
A pipe support comprising a. a pipe shoe for connection to a pipe; b. an upper bearing member connected to the pipe shoe to support the same, said member having a horizontal portion that curves upwardly at a pair of opposite edges into a pair of upwardly extending returns, said horizontal portion having a downwardly facing, flat, smooth, horizontal bearing surface fixedly secured thereto; c. a lower bearing member beneath the upper bearing member having an upwardly facing, low-friction bearing surface secured to and surmounting a layer of elastomeric material that in turn is secured to and surmounts a base plate for mounting the lower bearing member in a fixed location; d. said bearing surfaces directly engaging each other in free sliding relationship in any direction in a horizontal plane defined by said surfaces; and e. a guide member disposed on each side of the lower bearing member and positioned laterally of each said return of the upper bearing member at predetermined locations whereby to limit transverse movement of the upper bearing member.
Claim 4
Dependent Claim
173 words
A pipe support comprising a. a pipe shoe for connection to a pipe; b. an upper bearing member connected to the pipe shoe to support the same, said member having a horizontal portion that curves upwardly at a pair of opposite edges into a pair of upwardly extending returns, said horizontal portion having a downwardly facing, flat, smooth, horizontal bearing surface fixedly secured thereto; c. a lower bearing member beneath the upper bearing member having an upwardly facing, low-friction bearing surface secured to and surmounting a layer of elastomeric material that in turn is secured to and surmounts a base plate for mounting the lower bearing member in a fixed location; d. said bearing surfaces directly engaging each other in free sliding relationship in any direction in a horizontal plane defined by said surfaces; and e. a guide member disposed on each side of the lower bearing member and positioned laterally of each said return of the upper bearing member at predetermined locations whereby to limit transverse movement of the upper bearing member.
Claim 5
Dependent Claim
57 words
A pipe support according to claim 1, wherein said pipe shoe comprises a member having at least one upwardly projecting, plate-like portion having an upper periphery, each said periphery being of toothed configuration whereby to permit removal of the tips of the teeth to tailor the shoe to provide a desired invert when secured to a pipe.
Claim 6
Dependent Claim
17 words
A pipe support according to claim 1, wherein the pipe shoe is of inverted Tee-shape in cross-section.
Claim 7
Dependent Claim
16 words
A pipe support according to claim 1, wherein the lower bearing surface is formed of PTFE.
Claim 8
Dependent Claim
24 words
A pipe support according to claim 1, wherein a layer of insulating material is disposed between the pipe shoe and the upper bearing member.
Claim 9
Dependent Claim
15 words
A pipe support according to claim 2, wherein the guide members are faced with PTFE.
Claim 10
Dependent Claim
23 words
A pipe support according to claim 14 comprising a pipe shoe stem having an upper edge or edges of serrated or toothed configuration.
