ABSTRACT:
An apparatus for straightening a rail spike or the like includes a pair of said facing support arms mounted for pivotal movement about spaced axes on a frame, male die blocks mounted on the arms for movement therewith toward confronting angularly related surfaces of a female die member. A plurality of such female die members may be mounted on a rotatable support table such that the support surfaces of the female dies define radially extending angular grooves. The support table may be incrementally rotated for sequentially effecting a spike straightening operation, the table being locked at the spike straightening station and thereafter automatically ejected.
