Abstract

1,103,800. Advancing mine roof supports. RHEINSTAHL WANHEIM G.m.b.H. 29 Dec., 1965 [3 Feb., 1965], No. 55046/65. Heading E1E. In an advancing mine-roof support comprising two or more frames arranged in parallel a cantilever extension 11 is supported from two or .more adjacent props as by pivoted jacks 9, 9a. The jack 9, 9a may be pivotally secured to a second jack 12, 12a arranged as shown. For minor modifications and layouts Figs. 2 - - 5 (not shown) should be referred to.
