Abstract

311,064. Donaldson, J. April 10, 1928. Drills.-Machines for drilling shot-holes in coal &c. are supported on a strut 1 by an adjustable collar 5 to which is pivoted a rack 8 engaging the coal face. The fluid or electrically operated drill has a lug 10 sliding on the rack bar for feed by a lever 12 a spring pawl 15 preventing reverse movement.
