Abstract
A head-held, pressurized fluid operated, shears unit for use in the processing of poultry and the like. The shears unit has a body member having a weight and size for ready grasp by a user. One of the cutting blades is fixed in position, and the second blade is pivotally-mounted so as to move toward and away from the first blade to effect a cutting action. The motion of the pivotal blade is effected by connecting that blade, through a pivotal linkage, to a reciprocatable piston rod that extends from a forward end of the body member. This piston rod is fastened at a second end to a double-acting piston within a piston cylinder in the body member. A master valve operated by a lever for grasp by a user directs the pressurized fluid to one of two sides of the double-acting piston so as to effect moving of the piston and piston rod and thus opening or closing the pivotal blade with respect to the fixed blade. When the body member is fabricated from machinable plastic, the master valve includes a valve body received in a cavity within the body member with the valve stem moving within this valve body.
