Abstract
1,062,755. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. Oct. 8, 1963, No. 39600/63. Heading E1E. In a self-advancing mine roof support system comprising a series of frames d, f connected in pairs by shifting cylinders o acting through springs p, r on the floor bar of each frame so that the frames d, f are advanced alternately, at least one of the frames d has an additional shifting cylinder s detachably pivoted in a cup t near the roof bar k, m thereof, the body of the cylinder reacting on a chosen part of a chain u, v detachably connected to the adjacent frames. The cylinder s may be supported by a chain (not shown) and is manually swung to any desired in-line or oblique position. It may thus be used for assisting the advance of a frame or correcting the position of a tilted frame. Each frame, Fig. 2 (not shown), comprises a floor bar (i), two hyldraulic props (g), (h), and a resilient member (n) connecting the prop heads (k), (m).
