1,252,346 Jan. 01, 1918 Lathe headstock Franklin Hardinge Chicago, IL Back geared head for quick-change swing. Original Application 28 Jan 1915. Patent was then divided and refiled on 8 April, 1916.
"My invention relates to lathes and has for its object the provision of an improved lathe head stock wherein the end shake of the cone pulley and the end shake of the spindle are entirely independent so that the cone pulley is free to vibrate independently of the spindle and thus insure steadiness of the spindle and the work carried thereby when accuracy is an important element. This application is a division of my co-pending application Serial No. 4,841, filed January 28, 1915. In carrying out the objects of my invention I provide a head stock containing the usual front and rear bearings in which is journaled the spindle. An end thrust plate is secured to the spindle and acts against an end thrust bearing positioned between it and the front face of the rear bearing of the head stock. The end thrust of the spindle is thus taken up by the thrust plate and the bearing. Mounted around the spindle between the front and rear bearings of the head stock and arranged to have certain longitudinal movement relative to the spindle I provide a cone pulley which may, if desired, be connected with the spindle or the thrust plate so as to rotate therewith. My invention finds particular utility in a lathe head stock wherein back gearing is employed to cause the spindle to rotate at a different speed than the speed of the pulley. In this construction the end thrust plate can conveniently form one of a pair of gears mounted on the spindle for obtaining the desired gear ratio between the cone pulley and the spindle. Adjusting means is provided between the thrust plate and the end thrust bearing so that any end shake of the spindle may be easily and quickly taken up. A further object of my invention is the provision of means for locking a face plate of the class described in my Patent No. 894,635 to the lathe spindle so that accidental displacement thereof is prevented."
