Abstract
An improved drum-cutter mining machine design which transmits force exerted upon a drive wheel during translation of the mining machine along a rack structure to the machine. A protective housing encloses gears and a drive wheel in a manner such that feed forces exerted upon a drive wheel are transmitted through the housing to the mining machine.

A drum-cutter mining machine for longwall mining operations in which the drum-cutter mining machine is translatable along a longwall conveyor, said mining machine including:
- a machine body;
- a capstan supported from said machine body, said capstan supporting internal drive motor means and said capstan forming a vertically extending sidewall positioned above the longwall conveyor;
- a recessed area forming a cavity on said sidewall of the capstan;
- an aperture extending through the recessed area of the sidewall for allowing an output shaft butt of the drive motor means to extend therethrough;
- a housing removably positioned in the recessed area of the sidewall, said housing forming an enclosed area therein;
- means for fastening the removable housing to the sidewall of the capstan in a plurality of desired orientations;
- gear means positioned in said enclosed area connected with the output shaft butt of the drive motor means;
- and
- drive wheel means connected with said gear means and positionable to engage a conveyance means to allow translation of the mining machine therealong.
