Abstract
1,141,485. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. 13 Sept., 1966 [20 Sept., 1965], No. 40945/66. Heading E1P. In an advancing mine roof support assembly comprising two frames arranged in parallel with an advancing jack therebetween and wherein the component parts of the jack are respectively connected to spring suspension means 5 or 6 of a frame by an axle member 7 or 8, a connecting link 14, 16 is disposed between the jack and the base of one of the frames to prevent misalignment in inclined seams. The link may consist of a pair of pivotal fishplates as shown, a helical spring, a housing containing compression springs or a universal joint for fuller details of which the Specification and Figs. 2-5, (not shown) should be referred to.
