Abstract
This relates to a batting wheel particularly useful in a surface cleaner for batting abrasive particles against a surface to be cleaned. The batting wheel includes a hub which carries a plurality of axially spaced collars. At the ends of the batting wheel there are vane retaining plates of which at least one is removable so as to facilitate the removal and replacement of vanes. Each vane includes a flat blade and a retaining enlargement at the radially inner end of the flat blade. The collars are provided with axially aligned, circumferentially spaced slots for receiving the anchoring portion of a vane with each vane having an enlargement which is received in an enlarged opening in the respective collar. The enlarged opening is disposed at the inner end of a slot which receives an axially inner end of the flat blade. This permits the opposite batting faces of the flat blade to be selectively presented for batting abrasive particles.
