Abstract

960,824. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. Aug. 11, 1960 [Oct. 9, 1959], No. 27891/60. Heading E1E. In a modified advancing mine roof support as disclosed in Specification 866,240 the piston rod 20 of the advancing cylinder 13 for the independently movable roof support units 11, 12 itself forms a cylinder in permanent communication with a pressure source 15, 16, 17 for continuously urging a plunger 21, 23 and hence the conveyer towards the coal face, the elastic intermediate members of Specification 866,240 being consequently dispensed with.
