ABSTRACT:
A rotary scraper including a spool with fingers integral therewith and projecting radially therefrom, with the fingers striking the work surface as the wheel rotates, thereby to impact the work surface; the fingers are arranged in a plurality of comb-like structures with the base of each comb inserted in a slot parallel to the axis of the spool. Each comb is locked in place by a cylindrical cover for the spool having a slot displaced radially from the slot in the spool into which each comb is inserted. Each comb is therefore held in place by the S shaped bend thus induced and is curved away from the direction of rotation from the spool. The fingers of each comb are relatively flexible. The curved portion of each comb outside the cover acts as a support for the fingers of the next adjacent comb should they be flexed inwardly beyond the desired point.
