Description: |
| Claim:
The invention has particular reference to the type of chuck in which a number of jaws are simultaneously actuated radially to and from work-engaging jaws, as by a pneumatic cylinder and piston. In such devices, a precise adjustment of the respective work-engaging jaws is essential in order that the several jaws may simultaneously engage and release the work and precisely support it exactly on center. |
