(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, A Gear Cutting,
Milling, or Planing, subclasses 64-242.
(5)
Note. The term "rotation", as used in conjunction
with severing apparatus, is taken to require at least 360° of
unidirectional motion; which motion must be continuous. A series
of intermittent arcuate movements of work during severing, which
may add up to 360° or more is not considered to constitute "rotation".
See Class 83, Cutting, 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 Cutlery, or as a device for this class
(82) and claimed generically are to be classified here (82) and
cross referenced to Class 30.
