Abstract

1,220,979. Chucks. ROTOMORS S. R.L. 4 Nov., 1968 [20 Nov., 1967], No. 52224/68. Heading B3B. A chuck having jaws 6 movable radially simultaneously by a scroll plate 9 rotated by a toothed rim 14 and level gear 15 has the engaging faces of the scroll groove 10 and teeth 11 of the jaws inclined towards a point on the axis 12 so that axial movement of the scroll plate 9 simultaneously moves the jaws 6 radially. In this way the chuck can be altered manually by means of a chuck key and bevel gears 15 to the approximate size of a batch of workpieces and then final clamping can be achieved by axially moving the scroll plate 9. The scroll plate 9 is moved by connecting it to a bushing 13 which is moved by a fluid-pressure actuator rod.
