Abstract

1,093,334. Advancing mine roof supports. HERMANN HEMSCHEIDT MASCHINENFABRIK. Feb. 17, 1966 [Feb. 17, 1965], No. 7048/66. Heading E1E. In an advancing mine roof support comprising two frames 1, 2 arranged in parallel with an advancing cylinder 5 and a steering cylinder 6 therebetween, the support is connected to the conveyor 10 by an elastically flexible coupling rod 9 which is slidably guided in rings 7, 8, is pivotally fastened to the conveyor and, has limit stops adapted to co-operate with the guide rings for actuating sequence control valves 11, 12.
