ABSTRACT:
A pivoting ejector for an elevator scraper including an ejector member pivotally attached to the scraper bowl capable of undergoing forward movement therein to urge earth material from the bowl for discharge, while undergoing pivotal movement to prevent contact of the elevator member with the elevator. A hydraulic control circuit governs the amount of forward and pivotal movement of the ejector member during discharge of the scraper, and further effects upward movement of a pivotally mounted elevator, either independently or in cooperation with the ejector member.
