Abstract
A cutting implement having a plate with a curved, sharpened edge which is rotated to traverse the location of a work piece. The plate is shaped so that the rate of advance of the sharpened edge through the location decreases as the angle of rotation increases, thereby compensating for the gradual reduction in the mechanical advantage, and producing a nearly constant power requirement.
Claims18
A cutting implement, comprising, a frame, said frame including means for defining a work support at a predetermined location at which a work piece to be cut is positioned during the cutting operation,
- a plate having a curved sharpened edge and mounted on said frame for rotation about an axis,
- said plate being shaped and said axis being positioned relative to said work support so that as said plate is rotated said edge traverses said location,
- characterized in that said plate also is shaped so that the rate of advance of said edge through said location as a function of the angle of rotation of said plate decreases as the angle of rotation increases.
