Abstract

241,110. Hurd, F. W. April 18, 1925. Coal-cutting machines.-A cuttercarrying block, integral with or attachable to a cutterchain link or cutter disc, has one or more undercut slots 7 extending substantially parallel with the direction of travel and tapering rearwardly, so that correspondingly-shaped cutters 8 arranged in the slots are wedged more securely by the thrust of the cutting operation. The cutter block may have a substantially semicircular head 1. Cutters in adjacent blocks are staggered. Specification 240,733 is referred to.
