Abstract: An elevating scraper adapted to be towed by a tractor to perform earth-grading operations and the like including a vehicle frame, towing means on the frame, and a forwardly open scraper bowl located on the frame and terminating in a lower, forwardly extending scraper edge. An upwardly and rearwardly extending elevating conveyor assembly is mounted on the frame forwardly of the scraper bowl and spaced from the scraper edge, and a support surface is situated closely adjacent the conveyor assembly and cooperates therewith so that material may be elevated by the conveyor assembly and supported during such elevation by the support surface and moved into the scraper bowl. The support surface is perforate so that material of large size will be directed to the scraper bowl while smaller sized material will pass through the support surface to the underlying terrain.

Abstract: A self-loading auger scraper has a sealed auger supporting bearing assembly that includes a fixed lower housing secured to the floor of the scraper bowl and an upper housing rotatably mounted in bearings in the lower housing. An auger drive means is supported on a cross beam at the top of the bowl; and the upper bearing housing and the drive means have generally coaxial opposed square stub shafts which are loosely but non-rotatably engaged by square sockets in the bottom and top of an auger shaft to provide slip connections. The length of the auger shaft is such as to permit the auger to float while maintaining the slip connections.
