Abstract
192,818. Wild, M. B., Dunn, W. H., and Wild &. Co., Ltd., M. B. Nov. 17, 1921. Coal-cutting machines. - In a coal-cutting machine, the main sprocket wheel a engaging the haulage chain s is arranged on a vertical axis centrally at one end of the machine and is larger than the symmetrically and oppositely arranged guide sprockets c, d. The driving mechanism comprises a pinion n adapted to be clutched either to a driven worm wheel g or to a gear m; the sprocket a is driven at low speed through gearing g, l, j, k, m, n, o, p, q, or at high speed through gearing g, n, o, p, q. The driving worm f is actuated either from the main engine or from an independent engine. Channels &c. in the machine frame guide the haulage chain when it is employed for adjusting the cutter jib. Specification 192,526 is referred to.
