ABSTRACT:
A chuck for use in lathes and on other work equipment has a jaw carrier that is mounted in a central bore of a chuck housing on a pair of pivot pins and is capable of being indexed or rotated 180.degree. within the chuck housing while a workpiece is held in chuck jaws supported on the jaw housing. The indexing permits performing operations on the opposite ends of the workpiece without unchucking the workpiece from the jaws that are carried on the jaw carrier. The construction of the chuck permits obtaining adequate jaw gripping force and a positive drive between the chuck housing of the workpiece and the indexing jaw carrier. The chuck greatly increases the versatility of machine tools and yet is easily constructed with existing tools itself because it doesn't involve complex interfitting parts.
