ABSTRACT:
A spike driving machine is disclosed in which a hole sensing device and spike holder are driven in toward a rail under the action of a fixed stroke piston and cylinder until a stop engages the rail. The stop has been previously adjusted to line up the hole sensing device and spike holder the correct lateral distance for engagement with the tie plate holes. Excess travel of the piston and cylinder is taken up by providing a flexible connection between an X-frame carrying the hole sensing device, the spike holder and a drive head and a Y-frame which is fixed in the lateral direction. The stroke is chosen to align the spike holder under the drive head. Thus, the arrangement can be used for rails of differing thickness simply by adjusting the stop appropriately.
