Abstract

462,551. Coal-cutting chains. ANDERSON, BOYES, & CO., Ltd., and ANDERSON, A. Sept. 12, 1935, No. 25323. [Class 68 (i)] [Also in Group XXII] The pick-carrying blocks of a cutter-chain for a coal - cutting machine each comprises a bridge member 1 constituting the pick box, and separate side plates 2 secured to the bridge member by welds 5, 6. Preferably, a projection on the bridge member extends between the side plates. The pick-receiving sockets are formed by drilling and broaching before the welding operation.
