Filed: 1945-10-27
Abstract: 603,674. Chucks. HERBERT, Ltd., A., and LLOYD, A. H. Oct. 27, 1945, No. 28454. [Class 83 (iii)] A bar chuck for machine tools is operated by a reversible electric motor, mounted eccentrically to the machine spindle, the drive including a speed reduction gear and lostmotion connection. The drive from the electric motor 17, Fig. 1, is transmitted, through reduction gearing 18 and a torque member 25, to a clutch-operating shaft 32, lost motion being provided between the interengaging dogs 30. A toggle action mechanism, Fig. 3, is actuated from the drive-shaft 32, which moves a trunnion 45 laterally, this trunnion being connected to the operating- sleeve of a bevelclosing collet chuck. The lost-motion connection allows the motor to attain its maximum speed before operating the chuck in both directions and the slotted linkage provides a means for moving the chuck-sleeve and then locking it by the motion of the arms 35 and 36. The chuck, Fig. 4, is shown in the closed position. In opening the chuck, the sleeve 46 is moved to the right until the inclined face 61 allows a locking member 58 to pivot about its end 59, after which the internal sleeve 54 is free to move axially until the face 65 abuts the face 64 of the locking member. The movement of the sleeve carries with it the pressure ring 52 threadably attached to the sleeve, thereby releasing the closing action on the bevel-closing collet 50. The pressure ring and internal sleeve are relatively adjustable by a threaded key 55. In closing the chuck, the operating sleeve 46 presses the locking member 58 inwardly to abut the face 65 of the internal sleeve and move it to the left whereby the pressure ring urges the collet into the hollow spindle 48 of the machine. In a modification, the locking of the internal sleeve is effected by the use of steel balls in a groove in the spindle and cammed into locking position by the external sleeve being axially displaced. Specifications 391,823, 416,127 and 453,332 are referred to.
