DEFINITION

Classification: 198/560

(under subclass 523) Apparatus wherein the system comprises three or more conveyor sections, the first three sections of which are, in sequence, power-driven, gravity and power-driven.

SEE OR SEARCH THIS CLASS, SUBCLASS:

554, for a conveyor system under this heading having the same sequence of power-driven and gravity sections, but wherein the first power-driven section is a means for discharging a bin, which bin and power-driven section constitute a source of supply for the system.

561, for a conveyor system under this heading having a gravity section located between two runs of plural-run, power-driven section.

563, for a conveyor system under this heading having gravity and power-driven sections in a sequence which is the reverse of that of this subclass (560).
