DEFINITION

Classification: 198/348

(under the class definition) Apparatus having at least one driven conveyor section, said apparatus further having either a plurality of supply points or zones or a plurality of discharge points or zones arranged such that a discrimination may be made as to which supply or discharge point is to be used.

(1) Note. An outlet which is in constant communication with a conveying system and which can be pointed to direct the flow in different directions is not considered to constitute a selective or changeable destination and will not be found herein.

(2) Note. Recycling of the load back to a supply is not considered to comprise plural destinations.

(3) Note. The word arrangement as used in this title and the definitions indented hereinunder includes a single conveying section which is provided with either means to alter the length of travel of the load along the section so that different sources or destinations may be communicated with the section or means which allows selective supply or delivery of the conveying section from either side.

SEE OR SEARCH THIS CLASS, SUBCLASS:

536, for a conveyor system having a gravity section and wherein the last section of the system is adjustable, usually for the purpose of changing the exit path of material leaving the system.

537, for a conveyor system having a gravity conveyor section and having means to handle a portion of the load which becomes separated from the main flow path and wherein the separated portion may comprise a portion which is shunted to an auxiliary path for return to the main supply and eventual recirculation. 580, for a conveyor system having plural power-driven conveyor sections and wherein a portion of the load is recycled in a closed path.

209, Classifying, Separating, and Assorting Solids, appropriate subclass, for conveying arrangements which function to separate or sort conveyed articles based on either a physical characteristic of the articles or a load carried code; further, see

703+, and 705 for power-driven sorting tables and carriers, respectively. If a destination code is carried by a reusable

load carrier in lieu of a article itself, the patent will be placed as an original in this class (198). Also, a conveyor to transfer material (or an article) to a selected destination by use of computer memory is to be found in this class (198). The combination of a Class 198 device with a Class 209 sorting means is to be found in Class 209.

414, Material or Article Handling,

133, for conveying arrangements having some additional means external to the conveyor structure which allows an operator to control the destination of a conveyed load. Thus, Class 414 provides for patents claiming a conveying system having a central control means and a synchronous memory means, e.g., coded memory wheels, shift register system, etc. Examples of such arrangements are devices wherein a code would be impressed by an operator at a central station onto an analog system associated with a conveying section; that is, the code would be placed in a device separate from, but which operates in synchronism with the conveying structure. Operator actuated keyboards used to effect destination selection will likewise be found in Class 414.
