Abstract
442,965. Coal - cutting machines. EICKHOFF, A., (trading as EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI, GEB.), 176, Hunscheidtstrasse, Bochum, Germany. Jan. 8, 1935, No. 650. Convention date, Jan. 18, 1934. [Class 68 (i)] In a chain coal-cutting machine with a friction coupling in the drive to the chain sprocket to prevent overload, the coupling is provided on the shaft of the sprocket. As shown, motor d drives the cutter chain through gearing p, q, r, m, a spring-pressed cone-coupling a, b and sprocket k. The spring s is adjusted by a nut x and bolt z. The gear head h is slued by worm gearing y, t, pinion and internal gear i. In a modification, the cone coupling is replaced by a disc coupling arranged in the hub of the sprocket wheel.
