DEFINITION

Classification: 82/46

(under the class definition) Apparatus and processes.

(1) Note. At the time this and indented subclasses were established (1959) the bulk of art, was drawn from Class 164 (now Class 83, Cutting) concurrently undergoing reclassification. No attempt is now made, with respect to art falling within the turning concept, to distinguish between severing and lathe structure, except by schedule superiority.

(2) Note. Devices for "scoring" or "grooving", either disclosed as capable of use for severing or which score rather than sever because of work charateristics (distinguished from structural apparatus limitations), are also here classified if such devices otherwise fall within the class definition.

(3) Note. Included here are devices wherein the initial engagement of tool and work, either implied or specifically claimed, effects a piercing or incising of said work so that claimed means for relative rotation subsequently effect the severing operation.

(4) Note. Devices, otherwise falling within the above class definition, which utilize toothed rotary cutters to impart a shape or form, rather than length or size, to work are not classified here but are considered to be milling devices for Class 409, subclasses 64+.

(5) Note. The term "rotation", as used in conjunction with severing apparatus, is taken to require at least 360 deg. of unidirectional motion; which motion must be continuous. A series of intermittent arcuate movements of work during severing, which may add up to 360 deg. or more is not considered to constitute "rotation". See Class 83 for devices with such characteristics.

(6) Note. The relative movement of work and tool, or their resepective holding means, may be (1) the result of direct operator manipulation, (2) merely initiated by an operator, (3) fully automatic, or (4) any combination of these.

(7) Note. Classification of patents in this and indented subclasses requires that, in addition to disclosure appropriate for turning, there be claimed disclosure of (1) means for effecting relating rotation of tool and work as recited above and/or (2) tool infeed means.

(8) Note. Devices disclosed as capable of use as either an implement (or hand tool) for Class 30 or as a device for this class (82) and claimed generically are to be classified here (82) and cross referenced to Class 30.
