Abstract

829,786. Mine supports. BIENHULS, W. May 4, 1956 [May 6, 1955], No. 13760/56. Class 20(2) In a multi-part support suitable for use in mine shafts, roadways &c., the parts are flexibly held together to permit relative movement in a plurality of directions by rubber connecting members. The mutually engaging surfaces of the connecting members and the support parts may be provided by projections, e.g. on the connecting members and recesses, e.g. on the support parts, in which the projections engage. A number of embodiments are described, some of which are represented in Figs. 2, 3, 5, 9 and 10, in which the references 3, 6, 12, 31 and 21 respectively denote the rubber connecting members.
