  • Patent number: 4567656
    Abstract: A hand tool of the scissors type includes two pivotally-movable operating members or jaws or blades and two pivotally-movable handle members which members are readily separable from each other and are interrelated by a single pivot bolt extendable through the four components so that relative movement between each operating member and its respective handle member is precluded. The components are readily replaceable without supporting rivets, pins, screws or the like. Novel locking means allow easy tool operation both in the opening stroke preparatory for use and in the closing operating stroke and for assuming the safe locked position when the tool is fully closed.

  • Patent number: 4442603
    Abstract: The invention discloses pruning apparatus of the compound action hook and blade type. At the upper end of a longitudinally-extending handle, a stationary hook is fixed and extends upwardly therefrom in a plane parallel to and offset from the longitudinally-extending plane of the handle. It defines a downwardly-facing arcuately-shaped limb-engaging-surface for engagement with a limb. There is a movable blade which has a cutting edge and is operable to be reciprocated in an intersecting manner through cutting and return strokes with relation to the engaged limb and to the limb engaging surface of the fixed hook. A lever is pivotally mounted relative to the hook and a link pivotally interconnects to each of the lever and movable blade. The hook and movable blade and lever and link are each disposed contiguous to a common vertical plane.

  • Patent number: 4258472
    Abstract: An elongated pressure sensitive adhesive element for attachment within a recess on a component part of a shear, the upper side of the sheet carrying indicia for indicating the manufacturer or distributor or seller of the shear. The shear has pivoted crossed blades normally biased to opened position and is provided preferentially with a recess or inset in the spine or upper wall of the upper handle, into which an ornamental and/or information-bearing label may be inserted: (a) to impart a pleasing appearance to the tool; (b) to conceal an unsightly rivet which attaches the biasing spring to the handle; and (c) to carry information such as the manufacturer's or distributor's name, his trademark, tool model or number, or the like. The label and upper handle may be of contrasting colors to enhance tool attractiveness.

  • Patent number: 4156311
    Abstract: A shear having pivoted crossed blades normally biased to opened position is provided with a modular type latch allowing the single handed locking of the handles in a locked position or releasing of the locked handles into an opened position. The latch is integrated as a functional unit for ready association with the other previously assembled shear components by the mere insertion of the unit in situ whereat the shear is immediately available for operational use, securement being obtained without the need for screws or springs or hooks or like supplementary securement means, the latch being self retaining, once inserted. The salient feature is that the latch, which in one key sense is not fixedly related, is an independent unit which is a part of the total structure and serves as the means for latching and unlatching the blades in desired relationships.
