The illustration shows an improved design of Newton hori-zontal slab milling machine of a size especially adapted torailroad shop work. The design and construction are such asto make this machine very rigid and enable it to work themilling cutters to their full capacity. One of these machines,in operation in a locomotive shop, recently removed 18 a connecting rod in three minutes. The table is 30 ins. wide and may be made to mill anydesired length. The spindle is 6 ins. in diameter. The cross-. NEWTOH PLANER TYPE MILLTXn MACHINE. rail is of the angular face design, is eounterweighted, and maybe adjusted either by hand or by power. The spindle isoperated by means of a worm and a worm wheel, the wormwheel being of phosphor bronze and the worm of case-hardenedsteel. The center of the spindle may be raised 32 ins. fromthe carriage and the uprights will admit work 36 ins. main upright has a 22-in. face. The carriage is operatedby means of a spiral pinion and rack and has nine changesof feed through gearing, with a power quick traverse and handadjustment. The motor is bolted to an extension of the baseof the machine and is a General Electric variable speed , having a speed variation of 2 to 1. The millingmachine is made by the Newton Machine Tool Works, Phila-delphia, Pa.
