Abstract

984,430. Advancing mine roof supports. GEWERKSCHAFT EISENHUTTE WESTFALIA. July 28, 1961 [Aug. 13, 1960], No. 27517/61. Heading E1E. In an advancing hydraulic mine roof support comprising frames which are guided parallel to one another by resilient coupling means 7, 8, 9 and advanced by a shifting device and wherein each frame includes hydraulic props, a roof bar and a floor bar, the frames are spring loaded out of the vertical position-to urge their adjoining roof bars 5, 5<SP>1</SP> together-as by means of leaf springs 3 and resilient intermediate members 1. The roof bars are strengthened by guide plates 6. In a modification, Figs. 3 and 4 (not shown), the floor bars of adjacent frames slide directly on one another and are resiliently inter-connected by shifting cylinders and connecting members, adjustable connecting members also being provided to connect adjacent frame assemblies.
