ABSTRACT:
A controllable pivot specifically designed for the pan or tilt movement of a motion-picture camera support incorporating two separate braking mechanisms, the first being a drag brake adjustable to provide a controlled resistance to operation of the pivot and the second providing a pivot locking facility independent of the drag brake. In a preferred form the locking brake is a floating band brake operating in the oil of the hydraulic drag brake.
