Abstract

868,605. Chains for coal-cutters. AUSTIN HOY & CO. Ltd. Nov. 3, 1959 [Nov. 3, 1958], No. 35256/58. Class 24. Intermediate links 12 of a coal-cutter chain are cut away at 26 to accommodate a sprocket tooth. There is also space for a tooth between the links 12 for the next adjacent sprocket tooth. The link 12 is strengthened above a line 29. Projections 30 of the links 12 engage abutments 32 on the pick-carrying links 11 to prevent reverse bending of the chain.
