Abstract

1,176,476. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. 31 March, 1967 [1 April, 1966; 3 June, 1966], Nos. 14639/66 and 24890/66. Heading E1F. On a rotary, mineral-mining cutter head one or more guide vanes 3 are each of such a configuration and so mounted about the hub 1 of the head as to each form with the hub a helical pocket in which mineral mined by the cutter picks of the head is received and confined radially as it is moved axially of the head to be discharged from the supported end thereof. Preferably each vane involves a strip 12a or strips 11a, 12a forming a helical vane portion spaced radial from the hub and indined towards the supported end of the hub. This vane portion may be mounted on the hub independently of the helical portion 3a as shown.
