Abstract

997,904. Mineral-Mining machines. GEWERKSCHAFT EISENHUTTE WESTFALIA. May 7, 1962 [May 9, 1961], No. 17438/62. Heading E1F. In a mineral-mining plough two plough body-carrying carriages are coupled together by a beam 21 supporting a cutter carrier 8, which is spring-biased in an upward direction. Each body carries pre-cutters 17 and a pivotable plough and loading body 7, the ploughing edges 6 of the bodies being so arranged that one of the edges is operative on a face for a given direction of the plough therealong. Pivotally mounted at 4 on the beam 21, which is coupled to the carriages 1a, 1b by pivot pins 3, are two non-vertically adjustable ploughing units 5. The cutter carrier 8 pivots about a pin obliquely inclined to and secured to the top of a telescopic shaft 9 within which is a coil spring. The compression of the spring can be adjusted and the length of the shaft can be limited by worm and screw mechanism extending through the spring between the upper part of the shaft and the beam.
