DEFINITION

Classification: 198/570

(under the class definition) Apparatus including either (a) conveyors on separate conveying paths, or (b) conveyors which transfer a load from one to another.

(1) Note. The following arrangements are not considered systems with plural conveyors: (a) sets of reciprocating members tandemly disposed along the load conveying path, members of adjacent sets being interdigitated, and the load being supported on, and advance by, the sets successively, (b) two or more members which are fixedly secured to a single reciprocating means, such as a pressure actuated ram, and

which push articles or bulk material supported on the same surface or on different surfaces, and (c) plural reciprocating means, such as rakes, which positioned in side by side relation, are not rigidly connected together, and are arranged to cooperate in pushing a mass of articles or bulk material supported on a surface without separating means between the articles or bulk material.

(2) Note. Includes here as a system of plural conveyors is an arrangement wherein reciprocating members are driven by a single powered means (e.g., a crankshaft), and are not fixedly connected together if said members push articles or bulk material supported in separated relation on the same surface or on different surfaces (e.g., cans in spaced-apart-troughs, or rows of cans supported on the same surface, but separated by a partition).

(3) Note. Not included here as a system of plural conveyors is a first conveyor which is located above a second conveyor and which engages a portion of the load carried by said second conveyor and moves it backward (e.g., a doffing roller situated above an endless belt and rotating in a direction opposite to movement of the latter).

(4) Note. Included in this subclass are systems of conveyors such as endless belts placed side by side, with one belt carrying cans, and another belt carrying can covers, to workers at a can assembly area.

SEE OR SEARCH THIS CLASS, SUBCLASS: 497, for conveyors having cleaning scrapers which are provided with auxiliary conveyors for transporting removed detritus away from the main conveyor.

620+, for plural conveyors which coact by gripping a load therebetween, and which do not transfer the load from one to another.

793+, for pallets, carriages, or the like, which move around an endless path to convey loads supported thereon, plural drive means being spaced along said path for moving said load-conveying means.

817, for plural endless belts disposed side by side and jointly supporting the same load.
