Abstract

883,407. Mine roof supports. RHEINSTAHL WANHEIM G.m.b.H. May 31, 1960 [June 6, 1959], No. 19269/60. Class 20(2) A mine roof support assembly, Fig. 1, consists of two units A, B mounted by slides 7, 8 respectively on a common I-section guide 9 having abutment stops 10, 10a, each unit A, B consisting of a roof bar mounted on inter-connected hydraulic props 3, 4. In a modification, see Figs. 3 and 4 and 5 (not shown), the upper and lower ends of each hydraulic cylinder component are respectively connected to two vertically spaced guide racks as by slides in the form of stirrups. In a final modification, Fig. 7, the piston and cylinder components of each prop are secured to vertically spaced guides 9, 9<SP>1</SP> and the props of each unit are interconnected together by diagonal struts, the pistons being secured to the guides by releasable clamps.
