Ejector type scraper

An ejector type scraper, comprising a bucket having side walls and a bottom wall forming an open front end through which soil passes to load the bucket as it is moved forwardly over the ground surface, an ejector having a generally vertical front face extending across the bucket from one side wall to the other and supported by the bucket for movement between a rearward position as the bucket is loaded and a forward position to eject soil therefrom, and a pair of hydraulically operated, extendible and retractable actuators each connected at one end to a side wall of the bucket and at the other end to the ejector near one side edge thereof, each actuator being of the same size and comprising a cylinder, a piston reciprocable in the cylinder, and a rod on the piston projecting from one end of the cylinder, said actuators being reversed end for end so that the rod of one extends as the rod of the other retracts in order to move the ejector between its rearward and forward positions, first conduit means connecting the cylinders with one another on one side of the pistons thereof so that hydraulic fluid which fills the conduit means and the cylinders on said one side of the pistons will transmit the movement of one piston to the other, and second conduit means for introducing hydraulic fluid into one cylinder while exhausting it from the other cylinder on the other side of the pistons thereof.
