DEFINITION

Classification: 239/668

(under subclass 650) Apparatus in which the supply holder has an opening in a lower portion thereof and is so constructed, with at least one sloping wall leading to the opening, that the material is discharged by the action of gravity, and in which the strewing means rotates about an axis and receives the material in a direction substantially transverse to the axis.

(1) Note. For the meaning of "rotates about an axis" see (1) Note in subclass 681.

(2) Note. An agitating or disintegrating means may be used to assist the flow of material by breaking up lumps, but the supply holder must be so constructed that the use of a conveyor or ejector to move material horizontally is not necessary.
