Abstract
A tool balancer for manufacturing/assembly work has a swing arm mounted to an upright standard or column. A bracket mounts an articulating arm to the distal end of the swing arm. A tool holder is mounted to the distal end of the articulating arm. An adjusting saddle received on the articulating arm has a tooth which couples to one of a series of adjusting apertures on the articulating arm. Tension springs are connected between the bracket and the adjusting saddle to bias the articulating arm upward to offset the weight of a tool and to maintain the adjusting saddle in locking engagement with the articulating arm at the desired adjustment.
