ABSTRACT:
The present invention provides a brake that allows an object to rotate continually through its full range of movement, but allows the object to be reliably secured at any position within this range. The object is carried by a brake that includes a deformable cylindrical collar and a lever. Normally, a spring exerts force against the lever, which in turn exerts pressure on the collar, causing the interior diameter of the collar to become smaller. The collar then grasps the rod and prevents the rotation of the brake relative to the rod. A pneumatically controlled piston counters the force of the spring to allow the brake to rotate freely.
