Abstract

1,243,426. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. 26 Feb., 1969 [9 March, 1968; 16 May, 1968], No. 10258/69. Heading E1P. In an advancing mine roof support assembly comprising two frames 42, 44 and 33, 34, 35, 36 adapted to be advanced alternately by rams 48, 49, the units 33, 34 and 35, 36 are interconnected by resilient bridging means 37 having guide means 39 slotted at 40 to receive resilient bars 41, 46 arranged as shown to maintain relative, vertical alignment between the frames during advance. In a modification, see Figs. 1 and 2, (not shown) the central frame is replaced by a single prop connected to the outer frame units by a resilient bar slidably received in a guiding device carried by a resilient bridging element which also carries the cylinder of the advancing ram.
