Abstract

212,630. Marks, E. C. R., (Goodman Manufacturing Co.). Dec. 12, 1922. Coal-cutting machines.-The cutter chain of a mining-machine is formed of blocks connected by links 2, the body of each block having an uninterrupted inclined front face 8 and being rearwardly tapered; an inclined aperture receives a bit 6 which abuts against a pin 13 and passes through an aperture 17 in a clamping member 14 inserted in the block 1 from the rear and adjusted by a nut 19. The clamping member is held against rotation or falling out by a pin 20 and has a relatively hard gripping surface preferably formed by a set screw 23. A projection 11 on the block 1 supports the outer end of the bit. The bit is double-ended and of uniform section.
