Abstract

1,016,990. Advancing mine roof supports. HOESCH-BERGBAUTECHNIK G.m.b.H. Aug. 29, 1963 [Sept. 15, 1962], No. 34251/63. Heading E1E. In an advancing mine roof support system comprising two interconnected frame assemblies each including at least two props 1 mounted on a runner 2, one of the props is biased into the vertical position by springs 4 connected to the prop by a connector 8 which is adjustable for varying the position of the prop relative to its runner without altering the position of the spring relative to the said runner. The springs 4 are connected to the runner 2 by a swivel axle 5 and a spring 6 and are connected to all clamps 9 by an adjustable bolted slot connection 8, 10, see also Fig. 1 (not shown).
