Abstract

141,472. Cook, A. C., and Lauckner, J. E. March 5, 1919. Driving machines. - Relates to lathes in which the lead-screw and nuts are made equal in length and the screw is adjustable so that the traverse of the nut may be evenly divided over the whole length of thread, the nut being at the middle of the cut when the screw and nut are fully engaged, and consists in a device whereby the principle may be applied to any ordinary screw-cutting lathe. The ordinary lead-screw is replaced by a bar A to which a short lead-screw B, formed as a sleeve, is secured by taper pins F. The nut C has extensions D fitted with hardened brushes E accurately fitting the bar. Specification 17269/15 is referred to.
