Abstract

1389358 Escalator and passenger conveyer handrails WESTINGHOUSE ELECTRIC CORP 22 Aug 1973 [23 Aug 1972] 39713/73 Heading B8A The handrail 24 of an escalator or passenger conveyer, is driven by being pressed against the peripheries of a series of driving pulleys 70 by the action of spring loaded pressure rollers 92. Each pair of pulleys 70 is associated with a pair of pressure rollers 92 mounted on a pressure applying spring 110. If there is an odd number of pulleys 70, the rollers 92 are arranged in pairs respective to pairs of the pulleys 70, and a single roller 92 and spring assembly 110<SP>1</SP> (Fig. 8), is provided for the remaining single pulley 70. The pulleys 70 are driven by a drive belt, or chain 56, passing over sprockets 54 rigid with each respective pulley 70. The drive belt 56 is maintained taut by the action of a jockey pulley 80 loaded by an adjustment screw 84. Each spring 110 is prestressed to the shape shown in Fig. 2 from a curved shape (Figs. 4, 5B, 6B, 7B, and 8, not shown). It may have laminations 130, 132.
