Abstract
12,209. Myers, G. F. March 17. Undercutting &c.-Relates to a heading-machine in which a chain cutter mounted on a swinging frame cuts out blocks of coal or other material which are crescent-shaped in plan and of any desired vertical section. The spoil is removed by conveyers. The Figures show a machine in plan and elevation. A column 32 fixed in the centre of the room or heading carries a frame 25 on which guides 81 for the cutter chains are mounted, one on each side for cutting in either direction. A motor 34 mounted on the frame drives the chains, and also a pinion engaging a fixed rack 30 to give feed. A conveyer 56 on each side of the column 32 is driven from the motor 34, and delivers the coal &c. to a second set of conveyers 63 which load it into trucks. The height of the frame &c. is adjustable by screws 52. Antifriction pulleys, placed at the corners of the cutter chain guide, are provided with cutters so as to cut their own way. At the end of each cut, the column is moved forward and clamped again by the screw 55.
