Abstract:  
The present invention relates to particle-throwing apparatus, more particularly to apparatus of the type shown in U.S. Patent 2,732,666, granted Jan. 31, 1956. Such apparatus includes a wheel that rotates and forcefully projects a directional stream of particles for impingement against work pieces that are to be cleaned, peened, or otherwise treated by the particles. Among the objects of the present invention is the provision of novel constructions for use with the above wheels to simplify their manufacture and maintenance.
