Abstract
1,189,667. Taking up slack in flexible elements. COAL INDUSTRY (PATENTS) Ltd. 15 Dec., 1967 [27 Oct., 1966], No. 48303/66. Addition to 1,012,432. Heading B8B. The arrangement described in the parent Specification 1,012,432 for feeding power supplies to a longwall mining machine 10 is modified for use on an inclined seam in that the fixed point 16 for the cable carrying chain 14 is spaced uphill of the mid-point 17 of the machine path so that a loop of chain 14a remains when the machine reaches its uppermost limit of travel, the loop being continually urged downwardly of the incline. The loop 14a is engaged by a pulley 18 which through a cable 19 is urged downwardly by an hydraulic winch 20 at the lower end of the path, the winch motor acting as a pump to produce a downwards force as the loop moves upwards.
