Description:
The nature of my invention consists in so constructing a watch-maker's pivot-lathe as to obviate all the difficulties arising from the breaking of pivots when cut or turned in the lathe by a file, as is the case with all that have been hitherto made, and from defective workmanship caused by dependence on the accuracy of the hand or eye when these have become impaired or infirm.
