Abstract

1,023,820. Mineface conveyers. E. BRAUN, H. HALBACH, and G. BRAUN, [trading as HALBACH & BRAUN]. Feb. 27, 1964 [Feb. 28, 1963], No. 8137/64. Heading B8A. [Also in Division E1] Rollers 19 extending through openings in the side of troughing of a scraper conveyer at curves in the troughing facilitate movement of the scraper flights round the curves. The conveyer 8 is held against the coal face by piston- and-cylinder units 20 supported against props 21.
