Abstract: A counterbalance mechanism that achieves its counterbalancing force by the rotation of a shaft which places load upon a spring column. A screw-type drive moves a block axially along the shaft to compress the column, thereby imposing the counterbalance load. This screw-type drive, therefore, limits the application of the counterbalancing force to only one direction of rotation, corresponding to placing a load on the spring column. Also, the counterbalancing force increases in proportion to the number of revolutions the shaft is rotated. The counterbalancing mechanism is ideally suited to oscillating loads, such as the movement of a radar antenna, so that when the antenna moves in one direction, away from its neutral position, one of a pair of counterbalance mechanisms can provide the counterbalancing force; while, when the antenna rotates in the opposite direction, the other of the pair of counterbalancing mechanisms can provide the opposite counterbalance force.
