Abstract

904,532. Drivers. FISCHER A.G., GEORG. March 10, 1960 [March 11, 1959], No. 8555/60. Class 83 (3). A lathe &c. workdriver comprises a ring 4 secured to a driving spindle 1, on which work clamping jaws 7 are pivotally mounted, a second ring 9 rotatable on ring 4 and centred on the latter by springs 13 seated in a groove 26, each of which is secured at its opposite ends to the rings 4, 9, and a member 18 having leafsprings 14 which engage a groove 15 in the ring 4, to hold the member against radial and axial movement. Pegs 11 in member 18 engage slots 21 in the jaws so that on rotation of member 18, the jaws pivot about pins 8, and clamp or release the work 6. Cams 10 secured to extensions 28 on ring 9 engage pins 16 on the jaws, thus moving rings 4, 9 in opposite directions to pre-stress springs 13. In operation, member 18 is rotated counter-clockwise, Fig. 1, and pegs 11 rotate jaws 7 clockwise until pins 16 engage the ends 17 of cams 10, thus holding the jaws in the open position. A work-piece is placed between a line-centre 2, and a tailstock-centre (not shown), and member 18 is rotated clockwise, thus engaging pins 16 by surfaces 12 on cams 10, to move the jaws to clamp the work, such movement being assisted by springs 13.
