Patent number: 4476760Abstract: A fluid actuated cutting machine comprising a stationary lower blade and a vertically movable upper blade mounted at one end to a pivot rod. The upper blade is disposed at angle relative to the horizontal plane. The other free end of the upper blade is disposed beyond a vertical plane on which lies the cutting edge of the lower blade. A pressure arm, mounted on a cantilivered beam connected to the base of the machine, acts against any tendency for the upper blade to align its cutting edge with the cutting edge of the lower blade. During its downward movement, the upper blade is constantly drawn from its horizontally angled position relative to the lower blade towards alignment with the lower blade. This movement is resisted by the pressure arm. The resistance causes a firm cutting pressure between the two blades at the constantly moving contact point during the downward movement of the upper blade.Type: GrantFiled: February 18, 1983Date of Patent: October 16, 1984Assignee: Joseph Galkin CorporationInventors: Charles Block, Leon Mintz
