Locomotive Cylinder-Port Milling-Machine.—This machine (Fig. 220), built by Beaman & Smith, of Providence, R. I., is designed especially to mill the ports of locomotive cylinders. It can be readily attached to any standard locomotive cylinder. The frame or bed is fastened to the steam-chest seat, and the uprights are moved on the frame by means of racks and pinions until the milling-cutter is over the ports as desired, and are then fastened. The cross-head carrying the spindle-saddle is lowered similar to that of a planer, until the milling-cutter is at the required depth. The spindle is of steel, and runs in conical bronze bearings, with adjustment to compensate for wear, and is driven by a cone. The feed is automatic in either direction. |
