ABSTRACT:
In a lathe chuck, the jaws consist of two jaw segments, couplable with each other in different relative positions by means of a coupling member operatively linked to an actuating member by way of a positioning assembly. A latching assembly is provided for fixing in place the forward jaw part while the rearward jaw part is being moved. The latching assembly, the actuating member, and the positioning assembly are all adjustable in a linked relation to one another, so that the chuck span of the chuck jaws is automatically adjustable by the actuating member.
