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.
