ABSTRACT:
A combination comprising a blade block for mounting on an abrasive throwing wheel and a blade for mounting on the blade block is provided. The blade has a front surface and a rear surface, a first opening on the rear surface and a second opening on the rear surface spaced from the first opening. The blade block is provided with projecting means, such as a lug, adapted for insertion in the first opening on the rear of the blade. An abutment means contacts the rear of the blade. An opening in the blade block is provided, and the opening is intermediate the projecting means and the abutment means on the blade block. The blade is held in position on the blade block by locking means, such as a deformable, resilient wire, adapted for insertion in the second opening on the rear of the blade and for insertion in the opening in the blade block. The assembly comprised of the blade block, throwing blade and locking means is particularly useful in a rotatable, centrifugal, abrasive throwing device of the type frequently used for throwing sand, metal shot and other particulate material onto a surface to be cleaned.
