ABSTRACT:
A rail spike feeder, which may feed regular spikes, hairpin or lock spikes, and coach screws, uses a holder which receives spikes from a spike chute. The spikes do not assume any secure position from exiting the spike chute until after contact with the holder. The holder uses a four bar linkage arrangement such that the holder pivots about ends of first and second links at the same time the opposite ends of the links are swinging or pivoting about their mounts. This maintains a proper orientation for spikes moved into a spiking position whereat a spiker head, such as a spike hammer, may insert the spikes into tie plates and ties. A counterweighted finger assembly is used to maintain spike orientation as spikes are transferred from the spike chute to the holder.
