DEFINITION

Classification: 198/494

(under subclass 493) Apparatus wherein the section is provided with means which is positioned so that it can directly act on the section, or some part thereof, to remove soil or other unwanted or undesirable material therefrom.

(1) Note. The cleaning means is structure, in addition to that which is normally used to discharge the load. This additional structure may discharge the unwanted material to the same area that the load is delivered to if the unwanted material is of the same material as the load. For example,

belt conveyors are often provided with a cleaning implement located immediately downstream of the load discharge point, which implement strikes off load adhering to the belt beyond the discharge zone. This adhering load must be removed as it could have a deleterious effect on the conveyor; however, such material obviously could be carried along with the discharged load without contaminating the same. In fact, if the adhering load was not rejoined with the discharged load, material would be wasted. In such arrangements, the adhering load is, in fact, rejoined with the discharged load.
