Abstract
Abstract This invention relates to a pruning apparatus comprising a pole; pruning scissors mounted on one end of said pole, said pruning scissors being rotatable around an axis of rotation substantially perpendicular to said pole; and means including a control handle located at the other end of said pole for actuating said pruning scissors in such a way that the actuation of the pruning scissors is independent of their angular position about said axis of rotation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A pruning apparatus comprising: a pole; a fixed member secured to one end of said pole and supporting a first pulley; a rotatable member mounted for rotation with respect to said first member about an axis of rotation substantially perpendicular to said pole, said rotatable member supporting a seconD pulley; pruning scissors mounted on said fixed member and including a first branch secured to said rotatable member and a second branch pivotally mounted on said first branch; a control handle located at the other end of said pole; and a cable interconnecting the second branch of said pruning scissors to said control handle for actuating said pruning scissors, said cable passing through said first and second pulleys and the portion of said cable located between said two pulleys coinciding with said axis of rotation, thereby enabling actuation of said pruning scissors substantially perpendicularly to the axis of the pole around an angle of 360*.
Claim 2
Dependent Claim
154 words
A pruning apparatus comprising: a pole; a fixed member secured to one end of said pole and supporting a first pulley; a rotatable member mounted for rotation with respect to said first member about an axis of rotation substantially perpendicular to said pole, said rotatable member supporting a seconD pulley; pruning scissors mounted on said fixed member and including a first branch secured to said rotatable member and a second branch pivotally mounted on said first branch; a control handle located at the other end of said pole; and a cable interconnecting the second branch of said pruning scissors to said control handle for actuating said pruning scissors, said cable passing through said first and second pulleys and the portion of said cable located between said two pulleys coinciding with said axis of rotation, thereby enabling actuation of said pruning scissors substantially perpendicularly to the axis of the pole around an angle of 360*.
Claim 3
Dependent Claim
24 words
A pruning apparatus as defined in claim 1 wherein said pole is made of a number of tubular elements removably inserted in one another.
Claim 4
Dependent Claim
43 words
A pruning apparatus as defined in claim 2 wherein said pruning scissors are mounted on the first tubular element at one end of said pole and said control handle is mounted on the last tubular element at the opposite end of said pole.
