Abstract

726,622. Mineral-mining machines. COMPTON, C. E. July 10, 1953 [Feb. 4, 1953], No. 19199/53. Class 68(1). A breaker for freeing mineral from a face comprises one or more L-shaped rods 7 welded at the ends 10 thereof to a rotatable shank 2 in such a manner that the leading limb 8 of each rod extends rearwardly and outwardly from the leading portion 3f of the shank 2 in which a boring bit 6 is mounted. This breaker may replace the breaker of the mining-machine head described in Specification 675,440.
