ABSTRACT:
A method of reclaiming railroad spikes is disclosed in which the used spikes are collected and initially manually sorted to separate the bent and straight reclaimable spikes and to eliminate those damaged beyond reclaiming. The bent spikes are placed in a press and straightened, then the straight and straightened spikes are dumped into a sound insulated, sealed drum type tumbler and tumbled until clean and ready for reuse. The straightening press, tumbler, and a hoist for handling portable bins of spikes are mounted on a car moveable over railroad tracks and movement is controlled either by an operator who walks along the right of way collecting and sorting previously pulled spikes or the operator on the machine. The car is provided with a platform at its rear end for supporting the portable bins.
