Wood-turning includes inventions for reducing sticks of wood
to a desired form by means of rotary or non-rotary cutters brought
into engagement with the circumference of the continuously-rotating
stick or by means of rotary or non-rotary cutters revolving circumferentially
around and in engagement with the stick or that portion of the stick
to be reduced.
Wood-turning also includes machines provided with work-holders
which hold several sticks arranged axially in or near the circumference
thereof to form a cylinder of such sticks to be operated upon by
the cutter as though it were a single stick. These machines are
for producing sticks of polygonal section by turning the sticks
in the work-holder to successively present new surfaces to the cutter.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
In this class of machines rotating saw-cutters which engage
with the sticks while secured in the lathe-chuck or between the
centers are regarded as a species of rotary cutters and are not
clasified with saws in Class 83, Cutting.
Wood-turning does not include machines comprising a relatively-rotating
cutter and table or support upon which blocks or segmental strips
of wood are so secured that they may be brought into engagement
with the cutter which stands transversely to the sticks and feeds
longitudinally thereof. See the Search Note to Class 144 below
for the locus of such machine intended to shape wood.

cutter. This operation is continued until as many sides have been
produced upon the sticks as desired.
