Abstract
1,071,462. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. March 19, 1964 [Dec. 19, 1962], No. 23574/62. Heading E1F. In a rotary cutter drum mineral-mining machine 10 the pressure of the hydraulic fluid fed from a pump 14 to the cutter drum-driving, hydraulic motor 12 is used to regulate through suitable control means 22, 23, 24 the delivery of a hydraulic pump 20 driving the hydraulic haulage motor 18 so that the speed of advance of the machine is adjusted to a value consistent with the cutter motor maintaining a pre-determined power output. In a second embodiment the pilot supply 25 to the piston cylinder units 22, 23 controlling the setting of the swash plate pump and the control means 24 are replaced by a servo motor that is actuated by pressure variation in the supply line 13 to the cutter drum motor 12 to control the pump 20.
