Abstract
An X-ray tubehead counterbalancing mechanism devoid of springs, cams and chains is disclosed. The mechanism requires only a single adjustment to precisely counterbalance objects, such as tubeheads and the like. The mechanism includes a commercially available gas spring which is used in conjunction with parallel motion linkage assembly which carries the tubehead. The piston rod end of the gas spring is adjustable upwardly or downwardly in a direction substantially normal to the axis of the piston rod by means of a single adjustment screw cooperating with a clevis which pivotally mounts the piston rod. With such adjustment capability, the present mechanism will support and counterbalance tubeheads having wide variations in weight and inertia.
