Abstract
A counterbalanced power chuck such as may be used in association with power lathes is disclosed wherein each chuck jaw has a pivotable lever extending from a bore in the back face of the jaw through a stationary pivot section of the chuck body and into a bore in the opposing face of a radially movable weight. As chuck rotational speed increases, centrifugal force on the weight maintains jaw engagement pressure.
