Abstract

8523. Schaerer, O. May 8. Lathes.-Relates to a lathe attachment for backing- off milling-cutters during manufacture. A headstock a is fixed on the lathe bed w between the lathe headstock and the slide-rest. A spindle c for carrying the milling-cutter M is eccentrically mounted in a sleeve o, eccentrically mounted in a hollow spindle b in the headstock a. The spindle b is oscillated by a wheel d on it engaging through an intermediate wheel with a wheel e secured to a slotted lever f rocked by a pin x on the lathe driver-plate. A pawl i, adjustable round the wheel d, engages a ratchet-wheel h on the spindle c and drives it in the cutting direction only, the spindle being held against backward movement by a spring pawl k. During the cutting stroke, one tooth is backed off as shown in Fig. 6, the work being withdrawn from the tool z without rotation during the idle back stroke, so that the next tooth may be operated on. The desired eccentricity for backing off is obtained by angularly adjusting the sleeve o in the spindle b, the two being connected by a pawl and ratchet s. For side backing-off a screw pin n on a bridge on the headstock is screwed into engagement with one or other of oppositelyinclined slots m, m<1> in a split sleeve l clamped on the spindle b, thus imparting to it an axial reciprocation.
