Abstract

705,764. Chucks. VIDAL, E. M. Nov. 10, 1952 [Nov. 8, 1951], No. 26218/51. Class 83 (3) A chuck has jaws 13 sliding in inclined passages 12 in the body 10 and connected by cylindrical ends 20 in slots 21 to a jaw carrying member 22 freely supported on a splined portion 23 of the body and abutted by an operating member 27 sliding on the splines and moved axially to open and close the jaws by screwed engagement with an outer rotatable sleeve 33. In the selftightening chuck illustrated, the body is in two relatively rotatable portions 10, 11, the outer sleeve 33 being fixed to the front body portion 10 and the operating member 27, when moved forward to close the jaws, acting on the jawcarrying member 22 through ball or roller bearings 37. For opening the jaws, the members 22, 27 are connected by a spring-ring 26 expanded out of a groove 25, the ring having a slight axial clearance in the groove to ensure that the forward closing force is transmitted through the ball or roller bearings and not through the ring. If the interengaging threads become jammed during a machining operation, the body portion 11 can be rotated relative to the outer sleeve by a tommy bar inserted in one of a number of holes 39 in a ring 38 secured to the body portion. In a modified chuck, which is not selftightening, the body portions 10, 11 are integral, the ball or roller bearings 37 are omitted and the outer sleeve is rotatable on the body and has a flange between which and a flange on the body are mounted ball or roller bearings.
