DEFINITION

Classification: 198/550.01

Bin having a power-driven conveyor section for discharging or feeding discharge to a gravity or power-driven section:

(under subclass 523) Apparatus wherein the system comprises a receptacle (e.g., bin, tank, etc.) with a power-driven conveyor section for discharging it, which receptacle serves as a source of supply for the system, or the power-driven discharge feeds the discharge to additional conveyor section

either of the power-driven or gravity type.

(1) Note. This and the indented subclasses provide for a specific use of the type of conveyor section designated as "a bin with a power-driven conveyor section for discharging it", as discussed more fully in subclasses 523 and 540 above. These subclasses (550.01+) are the only areas within this heading wherein a receptacle and conveyor arrangement of this nature is accorded, for purposes of classification, any status other than that of its power-driven section, per se.

(2) Note. An elevating conveyor, having at its lower end structure, forming a "boot" from which the conveyor picks up material, usually is an example of a bin with a power-driven conveyor for discharging it. However, such is not the case in the event that structure of the boot is claimed in such a manner (e.g., "a forwardly and downwardly sloping rear wall leading to the path of the buckets", etc.) that its function as a gravity flow path cannot be ignored; in this situation, the two devices present a system comprised of a nonpower-driven conveyor section (gravity flow path) feeding to a power- driven section.
