  • Patent number: 6178644
    Abstract: A pruner assembly having hollow shaft with a longitudinal axis, a lower end, and open upper end, and a handgrip portion slidable along the longitudinal axis between a first and a second position. A shearing mechanism attaches to said open upper end of the hollow shaft, which mechanism includes a body having a hook adapted to receive and hold a limb, a cutting blade pivots on the body and against the hook to cut the limb. An arm member pivots to the body and couples to the blade so that pivotal movement of the arm member pivotally moves the cutting blade. A pulley is mounted to the arm member distal end and a cable guide pulley is coupled to the hollow shaft adjacent the open upper end for guiding a cable into and out of the open upper end without the cable contacting the walls thereof. A cable is provided for moving the cutting blade with respect to the hook.

  • Patent number: 6038773
    Abstract: A portable pruner for cutting limbs comprising a hollow handle assembly having a longitudinal axis, a lower end and an open upper end. The slidable grip portion is slidable along the longitudinal axis between a first and a second position. The cable runs through the hollow handle assembly to the outer engagement with the shearing mechanism. A shearing mechanism is attached to the upper open end of the hollow handle and includes a body having a hook adapted to receive and hold a limb. A cutting blade is pivotally attached to the body and selectively pivots against the hook to cut the selected limb. The pruner includes means for pivoting the cutting blade with respect to the hook wherein the pivoting means is responsive to movement of the sliding portion between the first and second positions. In one embodiment, the overall pruner length is adjustable with two clamped telescoping handle assembly segments and a mechanism for adjusting the operative cable length to accommodate the length variation of the pruner.
