Abstract: A device for parting a strip (6) of binding material that has been fitted around an article (5), such as a roll of sheet material or bundle of sections and the like, comprising a housing (1) provided with a support (12) for supporting the device with respect to the article (5), two blades (7, 8) connected to the housing (1), at least one blade (8) of which can be moved with respect to the housing (1), drive means (37) for moving the blades with respect to one another between an open position and a closed position for cutting through and/or snipping through the strip (6) when the housing (1) is bearing on the article, and a clamp (16) for holding the parted strip. The clamp (16) and one of the blades can be brought into interaction with one another to clamp the strip (6) between them.

Abstract: An automatically controlled cutting machine having a reciprocating cutting blade that is translated along a cutting path through a layup of limp sheet material under computer control includes an ultrasonic transducer that establishes standing waves along the length of the blade. The reciprocating motions of the blade shift the nodes in the standing wave to different elevations within the layup so that cutting is uniform in each ply of the limp sheet material. A drill used to produce marking holes in the material is also provided with ultrasonic means and aids the drilling in penetrating through the layup during drilling operations.

Abstract: The device comprises a shear adapted to be mounted to the boom of a backhoe or like machinery with relatively movable members and be actuated by a powered, movable member of the backhoe. The shear comprises a generally U-shaped support member adapted to be disposed about the top of the backhoe boom. The shear also includes a pivotally mounted cutter head adapted to engage an anvil section attached to the support member to shear an item such as a metal member inserted therebetween. A cutter head is actuated by the backhoe movable member and is pivotally returned to a raised position after a shearing operation by a biasing means connected to the cutter head.

Abstract: A band saw and a saber saw are both provided on the same table top working surface, and both are operable at the same time so that a pair of parallel cuts (either arcuate or straight) may be made in a workpiece at the same time. The saber saw blade has a vertical position thereof which is parallel to the vertical plane of the band saw blade, and the saber saw is adjustable with respect to the band saw to provide for cutting pieces of material of different widths. The saber saw blade is also pivotal from the vertical position thereof to a horizontal position wherein it is below the table top working surface, so that the band saw alone may be used. A workpiece resting member associated with the saber saw allows for pivoting of a workpiece with respect thereto to have an arcuate cut made therein by the band saw when the saber saw blade is in its horizontal position.

Abstract: A combination band saw, scroll saw and jigsaw having multiple blades driven by a common power source through a system of pulleys and belts, the jigsaw and scroll saw of which are activated by means of a belt-activated drive rod and piston rod system. The band saw is carried by a series of pulleys and the combination saw may be operated with all three blades simultaneously in operable position, or, in the alternative, each blade may be activated individually.
