Abstract

233,365. Sullivan Machinery Co., (Assignees of Holmes, M. P.). Feb. 19, 1923, [Convention date]. Drawings to Specification. Coal-cutting machines.-A mining - machine especially for low vein work has a feed operating member driven by mechanism including transmission mechanism disposed in, and longitudinally removable from, a longitudinal bore in the machine frame. Two speed transmission mechanism is employed, driven by a fluid pressure motor comprising intermeshing rotors, the gearing, motor and lubricating means for the latter being constructed and arranged as set out in the abridgment of Specification 211,475. Specification 233,366 also is referred to.
