.~.~ Reciprocal comminuting surface having openings
DEFINITION
Classification: 241/94
(under subclass 83) Apparatus in which a comminuting surface which is provided with openings for the passage of material has reciprocating motion, i.e., traverses the same path and reverses its motion at the end of this path.
(1) Note. The path may be rectilinear or curvilinear.

95, and 274, for devices in which the material is given a reciprocating motion relative to a stationary comminuting surface.
262+, for relatively reciprocating surfaces which cooperate to comminute the material.
