Abstract
Elevating scrapers are useful for loading material into a bowl and transporting the material to a location for dumping. When the elevator loads material into the bowl, a portion tends to slide forward between the side walls and the elevator and out of the bowl. The subject arrangement provides a blocking plate attached to the side wall which extends toward the elevator. The blocking plate blocks the reverse flow of material between the side wall and the elevator. This arrangement of components reduces the amount of time needed to load the material into the bowl.
