ABSTRACT:
In a mechanism or support for a television or movie camera which allows the camera to be tilted or pitched upwardly and downwardly, the weight of torque offered by the camera is counterbalanced by means of a series of accumulators or spring elements placed between the rotatable support for the camera and the stator portion of the support and adapted to be selectively engaged between the rotor and stator, depending upon the weight of the camera being used. Preferably each accumulator offers a restoring torque that is different from that of the other accumulators such that by selective engagement of various combinations of accumulators many different weights of cameras can be accommodated.
