Abstract

1,163,412. Mineral-mining drum. D. PALMER. 28 June, 1967 [29 July, 1966], No. 29904/67. Divided out of 1,163,411. Heading E1F. The inner end of each loader vane 7, 8 extending spirally about the body 1 of a mineral-mining cutter drum is beyond the inner end of the drum, cut away and supported from the body 1 by gussetting 12 to lie radially outwards of the periphery of the drum to be able to overlie a drum driving shaft bearing housing 11, which is of larger diameter than the body of the drum.
