ABSTRACT:
A counterbalance device for a rotary shaft comprises a sleeve member in the form of a short tubing or a handle which can be mounted on the rotary shaft. The sleeve member has an extension rear portion adapted to receive a bushing member to be mounted thereon. The bushing member is provided with at least two aligned openings. A rod can be inserted through these openings and be mounted on the bushing member by a set screw. At least one counterbalance weight can then be mounted on the rod to provide counterbalance for uneven weight distribution with respect to the longitudinal axis of the rotary shaft.
