Abstract

420,813. Coal - cutting machines. BERRY, J., 25, Meanley Road, and FOX, H. H., Samson House, both in Astley, Manchester. May 6, 1933, No. 13200. [Class 68 (i)] To remove debris made by a coalcutting machine, a scraper disc K is mounted eccentrically below the sprocket wheel which drives the cutter chain, a baffle plate D being reversibly mounted at either side of the machine to deflect the debris as it is flung from the disc K. A plate P prevents the disc returning debris to the cut.
