Description: |
| Claim:
In setting up a lathe for operation, it is necessary to adjust the tailstock center longitudinally so that the work may be engaged between the head and tailstock centers. Where the variation in work length is slight; the tailstock center may be adjusted longitudinally relative to the tail stock to engage the work. When the variation is greater than the adjustment range of the center however, it is necessary to shift the tail stock bodily to a position approximating the end of the work and the center then is adjusted to establish the bearing engagement. To permit tailstock adjustment, the tailstock is mounted slidably upon the bed and clamping means are provided to clamp it in selected position. In conjunction with these clamping devices, it is customary to provide a series of ratchet teeth in the bed and to equip the tailstock with, a pawl or similar latching device. to establish a positive lock between the tailstock and bed. This arrangement resists positively the thrust of the work against the tailstock center to, prevent the tailstock from shifting under vibration and impacts. |
