ABSTRACT:
A system for orientating a railway spike of the type having a head provided with a lip which projects at one location from the head. It is important to ensure that the lip is aligned in a predetermined angular position so that when the spike is driven in a tie by means of an automatic spike driver the lip will overlie the rail flange. The system involves a holding device, such as an electromagnet for holding a spike and a drive motor rotating the holding device and spike until a light path defined between a stationary source and detector is interrupted by the lip of the spike and at which point the drive motor is deenergized, in addition, a switch indicating a complete 90.degree. rotation of the spike is also activated so that one of the flat faces of the square section shank will face the rail.
