Abstract

890,168. Mine supporting arches and frames. PAURAT, F. W. Dec. 3, 1959 [Dec. 5, 1958], No. 41091/59. Class 20(2) A mine arch or gallery support frame comprises members 2 pivoted at 8 end to end and braced by struts 5, 6, 7 each connected between two pivots 8 which are separated by one or more of the other pivots. Some of the frame members may be yielding and consist of telescoping parts 1a, 1b the struts being connected to the entrance opening 15 of the outer part 1a. The strut 5 is a rod having forked connections 5a to the pivots, one prong of each fork being hinged to facilitate connection. The strut 6 comprises two pairs of strips adjustable by a pin 12 and holes 11 and the strut 7 comprises a bight of cable or chain surrounding two pivots 8 with the ends overlapped and connected by clamps to allow the strut to yield.
