Abstract

943,426. Pipe supports. A. J. E. GEAIRNS. June 2, 1961 [March 11, 1961], No. 8969/61. Heading F2S. In a constant pipe-line support comprising a cam pulley 2 rotatably mounted between a pair of plates la forming a bracket 1 and having chain parts 4, 6 anchored to its periphery and connected respectively to a rod 8 of a pipe support 5 and a spring device 7, the chain parts 4, 6 operate respectively over a semicircular portion 2a which is concentric with the cam pulley axis 3 and a cam-shaped part 2b of the pulley, the turning moment of the force of the spring device 7 about the axis 3 of the pulley being constant within a predetermined range of movement of the cam pulley. The chain part 4 maintains a lift in a constant tangential direction. The rod 8, which incorporates a turnbuckle 13, carries a plate 9 which is adapted to bear upon two cross-bolts 10 mounted between the plates 1a should the spring device fail. Bolt holes 11 may be provided higher in the bracket 1 to receive cross-bolts for cooperating with the plate 9 and holding the pipe e.g. during the erection of the pipe-line. The rod 8, having scale markings 28, passes between guide plates 17 which are welded to the bottom of the plates 1a and act as a marker. The bracket 1 is suspended from an overhead girder by a rod 15 which can swivel about its own axis and has a boss 14 rotatably mounted on a cross-bolt 16. The cam 2 can be shaped so that the chain portion 6 passes horizontally from the pulley with, or without, crossing the chain 4. If the chains cross the portion 4 passes between a double-chain portion 6.
