  • Patent number: 3963205
    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.
