DEFINITION

Classification: 241/202

(under subclass 201) Apparatus provided with mechanism for primarily presenting material to the comminuting zone and/or removing it therefrom or for controlling the flow of material to and/or from the comminuting zone.

(1) Note. The term "mechanism" is intended to denote means in addition to gravity for positively effecting the feed and/or discharge.

(2) Note. The feeding and/or discharging must be and operation other than the mere comminuting movement of the comminuting surfaces. However, means for moving a comminuting member out of comminuting position for the specific purpose of discharging material was considered a discharging organization for this group.

(3) Note. Material handling features in addition to those necessary to effect the mere presentation of the material to the comminuting zone or to remove the material from the comminutor were considered to be combined features which were more than mere feeding or discharging combinations and were classified in subclasses 101.01+ unless provided for

elsewhere.

(4) Note. The various feeding and/or discharging subclasses of this class for feeders and/or dischargers in combination with other types of comminutors. Where no feeding and/or discharging group was provided, the patents were classified with the particular comminutor combination claimed.
