Abstract

1,113,015. Shovel excavators. PRIESTMAN BROS. Ltd. 8 Oct., 1965 [9 Oct., 1964], No. 41339/64. Heading E1F. The dipper stick of a crowd shovel excavator is between its ends pivoted on a crowd arm pivoted on the outer end of the boom of the excavator. Pivotal movement of the stick with respect to the arm and of the arm with respect to the boom is controlled by rams acting between the stick and the arm and the arm and the boom with the first movement being used to provide a scooping action and the second movement being used for a crowding action of the scoop of the dipper stick.
