Abstract

925,832. Mineral-mining machines. AUSTIN HOY & CO. Ltd. May 1, 1961 [Feb. 16, 1960], No. 5493/60. Class 68 (1). Mounted at each end of the driving motorcontaining body 11 of a mineral-mining machine is a cutter chain-carrying loop jib 21 extending transversely of the body and about an area enclosing the cross-section of the body, whilst behind each cutting plane of the jib but ahead of the associated end of the body on which a jib is carried is means 32 that lies within the limits of the cut formed by the cutter chain to break up and shift laterally clear of the body mineral freed by the cutter chain. The means may be augers or a scraper conveyer having vertical, pick-armed scraper flights. Specifications 860,072, 813,719 and 811,490 are referred to.
