Abstract

1,167,912. Advancing mine roof supports. STAMICARBON N.V. 19 Jan., 1967 [19 Jan., 1966; 6 Aug., 19661, No. 2968/67. Addition to 1134862. Heading E1P. An advancing mine roof support assembly as disclosed in Specification 1134862 is modified in that the frames are interconnected by at least one coupling having components 10, 11, 14, 14', 10', 11' which hinge about vertical axes and have at least one leaf-spring part 13 or 13' so that the frames can pivot relative to each other in a vertical plane to acoommodate floor irregularities. For modified couplings utilizing spacers and adjustable hinges, Figs. 4-8 (not shown) should be referred to.
