  • Patent number: 11034036
    Abstract: Shear tools are described that are driven by a power assembly. In one version, the shear tools include a pivotally movable pair of lever arms. Upon activation of the power tool, the lever arms of the shear tool are pivotally displaced and urge a die along a shearing plane relative to another stationary die retained by the shear tool. In another version, the shear tools include a carriage and link assembly. Upon engagement and activation with a power assembly or power tool, a movable die is urged past a stationary die. Also described are systems and related methods utilizing the shear tools which enable convenient shearing or severing of workpieces such as strut channel.

    Abstract: The strap and band cutter is specially configured to produce smoothly rounded corners on the ends of a cut band or strap when opening palletized loads and other materials secured together by straps or bands for shipping. The cutter is a manually operated shear having two elongate lever arms joined by a pivot. The arms terminate in handles at one end and cutting jaws at the other. The cutter operates in double shear, i.e., a central jaw having two cutting edges passes through the opposite jaw and its two shear faces. The jaws are specially configured to produce rounded corners on the two cut ends of the strap or band after cutting, thus greatly reducing or eliminating the chance of injury from contact with one of the ends of the cut strap.

  • Patent number: 5483746
    Abstract: A hand operated slot-forming tool has an elongated nose portion having a mechanically advantaged dual edge cutting blade which is pivotally mounted over a slotted dual element anvil blade having shearing edges which work in opposition to the dual edges of the cutting blade in response to squeezing of handles on the tool which cause the cutting edges to close together in gradual shearing contact with stock to be slotted. The cutting blade can be placed in abutting contact with the right angled leg to produce a slot having one edge lying at the intersection of fight angle legs of a channel member. Uniform reproducible slots are produced.

  • Patent number: 5052258
    Abstract: A cutter for repeatedly cutting identical size pieces from a larger sheet of a semi-brittle and semi-rigid material includes an outer jaw affixed to a base and an inner jaw affixed to an arm that is resiliently connected to the base. The upper jaw includes a non-planar cutting edge that initiates the cut simultaneously at two locations located respectively on the right and left sides of the inner jaw and approximately midway between the front and rear of the inner jaw so as to produce a progressive scissors-like cutting action that proceeds simultaneously both forwardly and rearwardly from the aforesaid two locations and continues along the desired path.

  • Patent number: 5033194
    Abstract: An improved hand operated metal shears comprising an open lower cutter and a replaceable upper cutter that slides in a raceway in the upper handle and is forced downward thru a workpiece into the lower cutter when upper and lower handles are biased together thus shearing out a segment of a workpiece, the lower cutter being attached to the upper handle by a specially shaped post so that either straight lines, curved, or odd shaped cuts may be made.

  • Patent number: 4807363
    Abstract: An apparatus for trimming venetian blind slats is provided wherein a hand-held housing carries a removable anvil and blade; the blade is adapted to slide across the anvil, thereby causing a shearing action. The cutting surface of either the anvil or the blade is crowned so that the shearing action begins between the edges of the slat and extends transversely to each edge of the slat. A guide is provided to constrain the blade to a repeatable path across the anvil. The blade is driven by a lever actuated handle which extends longitudinally in a direction parallel to the longitudinal axis of the venetian blind slat. Operation of the handle by the user extends through a linkage connected to the blade to drive the blade across the anvil in a guillotine fashion. The removable blade and anvil can be made of hardened steel. A jig is also provided to facilitate trimming a predetermined amount of material from a plurality of slats.

  • Patent number: 4729170
    Abstract: A punch tool provides two generally longitudinal handles joined by a transverse pivot pin that is carried in a resilient bushing. One of the handles defines a straight bore that houses a sliding punch die and further defines a support for a mating, stationary die. The second handle is joined to the sliding die such that relative movement between the handles causes the sliding die to move within the bore, toward or away from the stationary die. Flexibility of the bushing permits the pivot pin to shift its axis longitudinally of the tool while permitting straight movement of the sliding die.

  • Patent number: 4689884
    Abstract: Scissors for cutting a V shape have two parts which are pivotably coupled. The first part has a V-shaped cutting block with two cutting edges which meet at an apex. The second part has a pair of cutting blades with cutting edges which cooperate with the cutting edges of the cutting block during relative rotation of the parts. The cutting blades are arranged such that the point at which the cutting edges of the cutting block meet engages the cutting edges of the cutting blades at different angles in the relative rotation of the two parts.
