Patent for a new and improved wood-working machine. This design "relates to improvements in wood-working machines, and is designed to produce a machine for automatically tapering material in either straight or curved lines. The improvement consists, essentially, in the employment of movable cutters approached or receded by means of a cam or cams, and is adaptable in forming staves and other portions of barrels or other articles in which the parts require a taper in straight or curved lines" (lines 8-17).
