Description:

Apparatus to be attached to Engine-Lathes for Turning Tapers

My improvement consists in attaching to the sliding portion of the head an index-wheel by means of a screw, the threads of which are graduated, as ten or twenty to the inch, and the periphery of the index-wheel cut with fifty or one hundred spaces or notches, so that their multiple or product will be one thousand, and therefore each space or notch in the wheel will represent one-thousandth of an inch, and each revolution of the index-wheel will be equal to one thread of the screw, and will be indicated on the graduated scale.
