DEFINITION

Classification: 241/203

(under subclass 201) Apparatus in which the moving comminuting surface or surfaces has a motion which is the combined result of a plurality of simpler motions one of which is rotation.

(1) Note. Mere nonsymmetrical arrangement of the rotary surface about a shaft (e.g., eccentrically mounted) was considered to give the surface compound movement. Accordingly, all devices having such eccentrically mounted surfaces were classified in this group.

SEE OR SEARCH THIS CLASS, SUBCLASS:

103+, and 107+, for plural surfaces having compound movement relative to a common surface.

220+, and the notes thereto for devices in which the comminuting surface has a simple rotary motion with no additional movement during comminution.
