ABSTRACT:
This disclosure relates to an automatically controlled scraper for moving particulate material onto a radial or star feeder for distribution thereby. The scraper includes a scraper bucket suspended from a radially extending arm. The bucket is connected to both a digging cable line and a lifting cable line, each of which is in turn connected to a suitable winch. The winches are controlled by clutches and brakes, each of which are optionally activated by interconnected automatic and manual control elements, whereby operation may be selectively changed from automatic to manual at the discretion of the operator.
