Abstract

822,781. Linings for mine workings. LOBBERT & CO. G.m.b.H. Sept. 17, 1957 [Jan. 26, 1957], No. 29178/57. Class 20(2) A frame for lining walls and roofs of mine workings comprises two parallel wire sides 1 connected by strutting 4 hooks 3 formed at one end being in the plane of the frame and hooks 2 at the other end being of right angles to the plane of the frame so that adjacent frames can be hooked together. Thehooks 3 may be turned towards or away from one another. Specification 800,658 is referred to.
