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. A rope and pulley assembly operatively interconnects with the movable blade through the lever and link and has a free end extended to the lower extremity of the handle for effecting pivotal movement of the movable blade through the cutting stroke responsively to a manually effected pull. Spring means effects movements of the movable blade through a return stroke. An adjustable grip in the form of a manually engageable member has a sinuous opening therethrough for the extension of the rope thereinto and therethrough and therefrom in the slip free positioning and grasping of the grip relative to the rope for the facilitating of the application of a force on and substantially parallel to the rope.
