Abstract
A portable extendable pruner for cutting limbs, branches and the like, the pruner including a hollow elongate housing assembly having a pair of telescoping tubular sections, a shears mounted on the outer end of one of the sections, an actuating element mounted on the outer end of the other of the sections, a first cable for connecting the actuating element to the shears, a second cable having one end connected to one of the tubular sections and the other end connected to the other of the tubular sections, and a compensating pulley assembly connecting the second cable to the first cable to maintain tension in the first cable when the tubular sections are moved axially relative to each other to adjust the length of the housing assembly.

A portable extendable pruner for cutting limbs and branches, said pruner comprising:
- a hollow elongate housing assembly including a pair of telescoping tubular sections;
- a shears mounted on the outer end of one of said sections and an actuating means mounted on the outer end of the other of said sections;
- a first cable mounted in said housing assembly for connecting said actuating means to said shears;
- a second cable mounted in said housing assembly and having one end connected to said one of said sections and the other end connected to said other section;
- and a compensating pulley assembly connecting said second cable to said first cable for maintaining tension in said first cable when said sections are moved axially relative to each other to adjust the length of said housing assembly.
A portable extendable pruner for cutting limbs and branches, said pruner comprising a hollow elongate housing assembly including an outer tubular section and an inner tubular section coaxially aligned in said outer tubular section,
- a shears mounted on the outer end of said inner tubular section,
- a tubular actuating member mounted on the outer end of said outer tubular section,
- a first cable connecting said actuating member to said shears,
- a second cable connected to said inner tubular section and to said outer tubular section, and
- a compensating pulley assembly connecting said first cable to said second cable to maintain tension in said first cable when said inner tubular section is moved axially with respect to said outer tubular section.
