Church in Record of RecentConstruction, No. 60. 284 AMERICAN ENGINEER AND RAILROAD JOURNAL. OPEN TURRET —PRATT & WHITNEY. IVi X 26 INCH OPEN TURRET LATHE. The new Pratt & Whitney 2l/2 x 26-inch open turret latheshown in the illustration is a universal machine suitable fordoing a large variety of work from the bar and on forgings andcastings, without continually requiring special appliances andexpensive cutting tools. To accomplish this purpose, many newfeatures, including a cross sliding turret, have been machine possesses practically all the flexibility and adapta-bility of the engine lathe. The extreme rigidity, powerful spin-dle drive, quick changes of speeds and feeds, heavy cross feed-ing turret and numerous adjustable stops, admit of narrowerlimits of error, as well as a marked reduction in the cost, overwork produced on the ordinary turret or engine lathe. It has a stiff head, and may be driven either by a direct-con-nected motor or a countershaft drive by means of a single pul-ley. The turret is mounted on a slide, having both positivep
