Abstract
1,079,187. Mine-roof supports. SALZGITTER MASCHINEN A.G. June 8, 1965 [July 10, 1964; March 27, 1965], No. 24133/65. Heading E1E. A multipartite capping for mine roof supports (Figs. 1, 2) comprises capping portions 5, 6 displaced relatively by a hydraulic cylinder 11, to which props 1, 2, 3 are pivotally connected, and bridged by a leaf spring 10, secured at 12 to the portion 6, relative to which the portion 5 is slidable and connecting the portions 5, 6. A part of the spring 10 can be biased towards the roof. The portion 5 overhangs the prop 1 at the rear and has fork arms 13, lower than the top surface 8 of the capping 5, 6. The portion 6 may also have a rear-extending leaf spring. The props 1, 2, 3 have pivot shafts 17 transverse to the advancing direction. In a modification (Fig. 7) the prop 1 has a resilient supporting device made up of an abutment member 20 slidable on the prop base 19 and a compression spring 22 between a stationary abutment 21 and the member 20.
