ABSTRACT:
A self cleaning sprocket for a roller chain comprising a circular disc having a plurality of outwardly extending teeth and between which are formed roller receiving pockets. At the base of each pocket extending radially inwardly therefrom are foreign material receiving niches which receive foreign material driven from the pocket by the engaging roller of the roller chain. The niches are U-shaped and extend from curved portions of the pocket which form the working faces of the sprocket. The sprocket and chain drive associated therewith is particularly well suited for use with an agricultural machine, such as a planter, which is used in a dirty and trashy environment.
