Abstract
1,000,732. Clamps for mine roof support bars; clamp fastenings. RHEINSTAHL WANHEIM G.m.b.H. Feb. 9, 1962 [Feb. 11, 1961], No. 5058/62. Headings E1E and E2B. A cantilever roof bar 22 is connected to a transverse roof bar 8 by a connecting element having opposed jaws 29, 31 for receiving the bar 8 and a pivoted tongue and fork connection for the bar 22. The jaw 29 is adjustably mounted on a screw-threaded extension 27, 28 of the connecting element and is actuated by a nut 30. Specification 1,000,733 is referred to.
