Abstract

1,198,507. Advancing mine roof supports. K. M. GROETSCHEL. 14 Nov.. 1967 [6 Nov., 1966 ; 15 March, ,1967; 4 Aug., 1967], No. 51724/67. Heading E1P. In an advancing mine roof support comprising three frames arranged in parallel with the central frame movahle .relative to the outermost frames Which are interconnected to form a common unit, the roof structure of the inner frame is interleaved with that of the outer frames so that lateral clearance extends therebetween and the relative angular positions of the frames are controlled to accommodate drift by steering means including guide devices 40, 41 acting directly between and situated at longitudinally spaced locations between the frames. At least one of the guide devices 41 is adjustable for steering purposes whilst the other device may be in the form of an abutment 40 fixed to the inner or outer frame as schematically depicted in Figs. 1-4, (not shown). The device 41 may include a vertical plate 44 which is moved in a transversely extending guideway 45 by a piston-and-cylinder unit 47, 48 acting on a pivoted lever 50 associated with retaining means 52, 53 Numerous modified arrangements of steering devices are disclosed arranged adjacent the roof or base .structures for details of which together with other minor details concerning flushing shield 16, roof and base structures, advancing rams and mode of operation the Specification and remaining drawings (not shown), should be referred to. Specifications 1,037,914, 1,037,916, 1,069,906 and 1.168.791 are also referred to.
