Abstract

769,328. Mineral - mining apparatus. DEUTSCHE KOHLENBERGBAU-LEITUNG. May 28, 1954 [May 29, 1953], No. 15851/54. Class 68 (1). A member b carrying two cutter knives facing in opposite directions is pivotally mounted on the base a of a plough type, mineral-mining machine, and is so connected to the haulage means by a linkage that the haulage means positively causes the member b to turn about a pivot c to present the leading knife in an operative position before the haulage means becomes effective to move the machine along the seam.. The linkage consists of a bar e, slidably disposed in a channel formed in the body a, a block h rotatably mounted on a pin f secured on the bar e and slidably engaging within an aperture formed in a laterally projecting extension of the member b. The pivotal movement of the member b is restricted by stops g that can be continuously or discontinuously adjusted.
