This invention relates to lathes such as are used for drilling and turning. Heretofore lathes have been provided each with a tail-stock adapted to slide along the lathe-ways and to be fastened at any point there on, and the tail-stock is usually furnished with a spindle fitted to slide parallel with the ways and in perfect line with the working spindle of the lathe. It is usual to provide the tail-spindle with a feed-screw for sliding it longitudinally in its bearings, and some lathes are provided with a hand-lever to be substituted for the screw to slide the spindle when a quantity of work is to be done that does not demand the steady firmness of the screw-feed, the lever being much quicker than the screw in operation. The objects of this invention are, first, to obtain the service of either the screw or the lever without the necessity of removing the screw to use the lever, and vice versa, and, secondly, to obtain the further advantage of the combined use of the screw and the lever.
