Abstract

1,059,557. Portable conveyers in mines. DOWTY MINING EQUIPMENT Ltd. Nov. 11, 1965 [Nov. 17, 1964], No. 46777/64. Heading B8A. [Also in Division E1] In an advancing mine roof support comprising two frames 3, 4, each connected to a conveyer 17 by an advancing jack 8, the frames are slidably coupled to a guide assembly 30 pivoted to the conveyer. The pivotal connection allows relative movement in a substantially horizontal plane and a limited amount of relative vertical movement. For details of the pivotal connection, Fig. 2 (not shown), should be referred to.
