DEFINITION
Classification: 241/109
(under subclass 107) Apparatus provided with mechanism for primarily presenting material to the comminuting zone or for controlling the flow of material thereto.
(1) Note. The term "mechanism" is intended to denote means in addition to gravity for positively effecting the feed. The feeding must be an operation other than the mere comminuting movement of the comminuting surfaces.
(2) 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.

301, for feeders and/or dischargers combined with comminutors where the latter was claimed so broadly as to fail to present a basis for classification in a specific comminutor group.
