摘要： A core chuck comprising radially movable exterior jaw members, means operative in response to a relative rotation between the jaw members and those means to apply a radially outward force to the jaw members, and biasing means for urging the jaw members toward a predetermined radial position. The biasing means comprise a band spring disposed in axially aligned recesses in surfaces of the jaw members, at least one of the recesses being provided with spring retainer means preventing removal of the spring from the recess in a radial direction.

摘要： CHUCK STRUCTURE FOR LATHES OR THE LIKE CAPABLE OF INTERNAL OR EXTERNAL CHUCKING EITHER MANUALLY OR AUTOMATICALLY. THE CHUCK STRUCTURE DISCLOSED HAS A PULLDOWN FEATURE IN BOTH INTERNAL AND EXTERNAL CHUCKING AND IS ADAPTED TO RECEIVE BAR WORK IN ONE MODIFICATION THEREOF. INTERNAL AND EXTERNAL CHUCKING IS ACCOMPLISHED BY PROVIDING SEPARATE SPACED APART JAW STRUCTURES WHICH ARE ROTATABLE ABOUT SEPARATE AXS PARALLEL TO AND SPACED RADIALLY FROM THE AXIS OF ROTATION OF THE CHUCK. AN INCLINED SLIDE IS PROVIDED IN EACH JAW STRUCTURE ACTUATED BY BELL CRANK MEANS SECURED TO THE JAW STRUCTURE FOR PROVIDING THE PULLDOWN FEATURE. THE BELL CRANKS OF THE JAW STRUCTURES ARE ACTUATED BY SEPARATE RODS IN ACCORDANCE WITH ROTATION OF AN INTERNALLY THREADED RING GEAR ENGAGED WITH EXTERNAL THREADS ON THE RODS IN ONE MODIFICATION AND IN ACCORDANCE WITH A PULL ROD CONNECTED TO AN ACTUATING MEMBER HAVING PORTIONS ENGAGED IN RECESSES IN THE ACTUATING RODS IN ANOTHER MODIFICATION.
