ABSTRACT:
A torque counterbalancing mechanism for use on tiltable tables, the mechanism comprising a cam operated on by a spring loaded cam follower so that their interaction produces a force equal and opposite to the torque generated as the tiltable table, with load, rotates either side of the vertical. At the null position, i.e. no torque, the spring is at rest with no pre-stressing and means are provided for changing the effective length of the spring, thereby changing the RATE of the spring, to adjust the mechanism to accommodate different heights of the center of gravity of the load or changes in load.
