Abstract: An improved pneumatic impact imparting tool includes a follower which is slidably accommodated in a recess formed on the inner end part of a rotor in a pneumatic motor. The follower is formed with a projection for allowing a ball to come in contact with a cam face as it is rotated together with the rotor. When the ball reaches the top of the cam face, the follower is displaced in the axial direction and enters a recess formed on the inner end part of an anvil to collide against stoppers in the recess. Thus, rotational movement of the rotor is transmitted to the anvil in the form of intermittent turning movement of the latter.

Abstract: An apparatus and improved method for transversely cutting strips of deformable material with a rotating cutting blade which is moved generally transversely across the strip at a predetermined rake angle and bevel angle. A vacuum applied to certain chambers of a platen draws the strip firmly against a supporting structure at two locations on opposite sides of a cutting line during the cut cycle. A lubricant is sprayed through nozzles onto the blade as it cuts the strip and blow-off nozzles remove excess lubricant during the cut and return cycles of the blade to prevent contamination of the cut strip edges. A release bar assists in disengaging the strip from the platen after the strip is cut. Grippers remove the cut strip and then an input conveyor advances the remaining strip toward the cutting line where the grippers pull the strip forward to a predetermined position for the next cut cycle.

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.
Abstract: A straight line shear has a pair of carriages which support opposed pairs of shear blade assemblies. These carriages are displaceable to shear gobs from molten runners of glass.
