Abstract

936,842. Coal breakers. A. OELLRICH, [trading as MASCHINENFABRIK UND EISENGIESSEREI A. BEIEN]. March 9, 1960 [March 17, 1959], No. 8367/60. Class 59. In a coal breaker for mining in which the passage crosssection between a base frame 1 and a breaker roller 4 mounted on a rocker 3 is adjustable by means of compressed-air operated cylinders 5, an air compressor 6 mounted on the rocker is associated with the cylinders. The air compressor is constructed as a piston pump, the piston-rod of which is connected by way of a connecting rod 7 to an eccentric or crank-pin on the shaft of the breaker roller. The air compressor is connected to the pressure chambers 5a, 5b of the cylinders by way of a compressed air tank 12. The pressure in the tank is kept at a predetermined value by means of a spring-loaded control slide 15 which, when the pressure is exceeded, connects the pressure chamber of the pump to atmosphere. A fourway cock 19 enables either of the pressure chambers 5a, 5b to be connected to atmosphere.
