The Niles Boiler-plate Planing Machine — Fig. 5 shows a boiler-plate planing machine, made by the Niles Tool Works, Hamilton, O. It will bevel the edge and square up a narrow caulking surface, plane plates 14 to 18 ft. long at one setting, and is arranged to plane any length by resetting the sheet. There are two separate tools on the tool post... The cut is taken both forward and back. A large steel screw operates the saddle. Brackets extend out from the back of the bed, carrying rollers for supporting the sheet and facilitating handling. A heavy clamping bar holds the plate securely in position. The bar is raised and lowered by screws at each end. No intermediate screws are required, hence the operation of setting is quickly accomplished. The driving pulleys are 24 in. diameter for a 2½-in. belt, and strongly geared to the screw. The screw is of steel. 3½ in. diameter. 2 in. pitch, and is supported in a continuous bearing, preventing sag or deflection. The nut is of extra length and surrounds three-fourths the diameter of the screw. |
