Abstract

10,045. Farnsworth, A. W. May 15. Tunnelling, machines and shields for. The shield a, with its cutting-edge b and advancing rams 11, is combined with arrangements for removing the face. These consist of ploughing-cutters h, which are traversed along the arms g of the revolving cutter head by screws i. The arms are attached to the boss f and the rim j, which is driven by gearing p, n, m from an electric or other motor A. Other gearing s v drives the feed-screws. Front and back plates 5, attached to the rim j, carry between them either fixed or pivoted cross-plates 7, which serve to collect and raise the cuttings to the hopper 9. The pivoted plates are tilted by stops thereon striking the hopper to discharge wet material. Shields surround the feed-screws and their gearing to exclude dirt.
