DEFINITION

Classification: 241/239

(under subclass 221) Apparatus in which a nonrotary surface which cooperates with the rotary surface is mounted so as to be adjustable or yieldable relative to the rotary surface.

SEE OR SEARCH THIS CLASS, SUBCLASS:

32, for means mounting a nonrotary surface for release upon overload.

37, for devices providing for automatic control of comminuting surface contiguity.

89, and 189, for similar arrangements wherein the rotary surface is a rotary striking member.

286+, for such devices in which the claimed invention is limited to the mounting of the nonrotary surface relative to the frame of the machine (i.e., the rotary member is not included significantly in combination).
