Abstract
741,904. Mineral-mining apparatus. JOY-SULLIVAN,. Ltd., and SMITH, W. M. July 13, 1954 [Aug. 24, 1953], No. 23263/53. Class 68(1) The centrally-disposed, conical breaker h of a mineral-boring cutter head, formed by a cutter-armed, open ended cylinder a and a scroll conveyer g secured to a rotatable and advanceable shaft f in which the breaker h is mounted, is reciprocated axially of the cutter head. As the shaft rotates the end of a plunger q, radially disposed therein, passes over a series of cam surfaces in a ring structure s secured against rotational movement and the plunger moves radially of the shaft to impart an axial movement to rod h' to the breaker h.
