Abstract

129,066. Poppett, G. June 1, 1918. Coal-cutting machines. - In a coalcutting machine, a hollow cutter-bar a has within it a stationary helical rod o, which conveys to a chamber p the grit and dust which enter the bar through holes n, n adjacent to the helically - arranged cutters b. A suction pump r is connected to the chamber p. The cutterbar is revolved by gearing g, e and is reciprocated through the engagement of a grooved cam i with a ball j carried by a stationary adjustable holder. The gearing is contained in a box c forming an oil bath and swivelling on a wheeled or other base-plate.
