DEFINITION

Classification: 144/422

Of different operating assemblages:

(under subclass 421) Subject matter including regulating the functioning of at least two disparate operating assemblages.

(1) Note. See the (1) Note under subclass 421 for an explanation of "operating assemblage."

(2) Note. This subclass is the locus of patents disclosing control of a sequence of operations performed by different operating assemblages responsive to a tool. For example, a device wherein a woodworking tool strikes a limit switch causing a cutter to cut the product of the tool, and/or causing a handler to discharge the product from the machine, would be found in this subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

429, for woodworking generally wherein the operation of a plurality of operating assemblages is responsive to a device other than a woodworking tool.
