Abstract
924,752. Mineral-mining machines. STAHLWERKE BRUNINGHAUS G.m.b.H. Dec. 28, 1960 [April 20, 1960], No. 44438/60. Class 68 (1). In a mineral-mining machine a plough member 6 is caused to swing in a horizontal plane about a pivot 7 at one end of a lever 5 by a jack 8, 8a extending between a bracket 6c on the plough member 6 and a pivot 10 on the lever 5, which can be angularly rotated about a vertical pivotal support 4 on a self-advancing frame 1 by a jack 11, 11a. The angular adjustment of the lever 5 about the pivot 4 allows the zone of operation of the plough body 6 to be extended transversely of the width of the frame 1.
