Abstract:
The surfacing and sliding motions of a lathe are connected by gearing for taper turning and boring, and for cutting threads on conical surfaces. The usual cross-shaft 2, in the saddle 1, has a pinion 3, gearing with a wheel 4, loose on a bush, keyed on the spindle 6, which is provided with the usual rack pinion. A wheel 7, keyed on the bush, can be coupled to the wheel 4 by a friction clutch, and can be geared to a wheel 12, on a spindle 11, by pinions 13', 15 or by the pinion 13, the pinions being carried by a reversing-plate locked to the saddle by a bolt 30. Change-wheels 16, 20 on the spindle 11 and the surfacing-screw 22 respectively, are connected by wheels 17, 19 on a quadrant plate 9. The wheel 20 is connected to the screw 22 by a friction clutch. |
