It is adapted for work requiring great accuracy,but the design being free from delicate parts, it is equally suit-able for heavy boring service. One of the important features of this machine is the locationof the spindle saddle within the post. This makes possible tliesymmetrical construction of the entire machine about the spindle. Horizontal Boring. Drilling and (Vlilling Machine axis and affords a very rigid support for the spindle. Thethrust is taken on two V tracks, one on either side of thespindle, eliminating the distorting strains which are inevitablein machines having the spindle and saddle on the front of thepost. The thrust, coming squarely against the bearing ofthe saddle on the post, tends to add to the truth of the aline-ment. The saddle has a vertical power feed for milling as wellas a rapid power traverse. This motion is transmitted through avertical screw which is connected by gearing to a similar screwin the outboard post, so that the spindle saddle and outer bear-ing alwajs move in unison. The spindle driving gear is enclosedwithin the saddle with a portion extending outward and exposedlor use as a face plate. The sinndle slides in a long sleeve whicli revolves in remov-able bearings, the main bearing being tapered so that adjust-ment may be made for wear. The spindle is driven through twolarge
