142 /   HD   WOOD TURNING



DEFINITION

Classification: 142/

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.

LINES WITH OTHER CLASSES

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.
