    摘要： A mobile machine mounted on a track for advancement therealong for removing irregularities from the surfaces of the rail heads comprises a machine frame, a tool carrier vertically adjustably mounted on the machine frame and arranged thereon for guidance along a respective track rail, and a cutter head on the tool carrier. The cutter head has a cutting tool capable of machining the surface of the head of the respective track rail continuously upon advance of the tool carrier along the track rail.

    摘要： The key seat slotter has a shank on which a pulley is adapted to be clamped. A broaching blade is slidable in a groove on the shank through the bore of the pulley. The key seat is cut in the pulley bore by manually pivoting a handle to effect repeated strokes of the broaching blade. The depth of the cut is progressively increased to the desired depth of the slot between successive strokes of the blade by incremental advancement of a tapered feed bar in the groove on the shank on which the broaching blade is slidably mounted.
