Abstract

241,231. Maschinenbau-Akt.-Ges., H. Flottmann & Co., (Assignees of Pfannenschmidt, C. G.). Oct. 13, 1924, [Convention date]. Coal-cutting machines.-The shaft m of the motor of a coal &c. cutting machine drives a pump k which compresses oil stored in the casing a and delivers it to a rotary engine comprising interlocking toothed cylinders h, i; the engine shaft g drives a sleeve e through worm gearing and a clutch o connects the sleeve to the shaft e of the haulage drum d. A cock n deflects liquid to the casing a to vary the speed of the haulage drum.
