ABSTRACT:
A reference mechanism for a spike driving machine is disclosed. The spike driving machine has a hole sensing device followed by a spike setter and drive head all of which sweep along a rail tie in a direction parallel to the rail. When the sensing device senses a hole it signals to the reference mechanism which references the hole to the setter and drive head which are following. The sweep continues until the setter and drive head are located over the hole at which point the sweep is stopped by the reference mechanism.
