ABSTRACT:
Apparatus for holding a railroad spike in a substantially vertical position while the spike is being driven into a railroad tie. The spike holding apparatus includes a support member adapted to connect said apparatus to a railroad spiking machine, a pair of jaws which rotatably depend from said support member at an angle to the plane of the rail which angle is large enough to avoid interference with rail anchors but not so large as to preclude sufficient mechanical leverage from being imposed on the spike to be held and actuators to to rotate said jaws relative to said support member and to one another. The first jaw of said pair includes a cradle adapted to receive a spike and further adapted to avoid interference with the spike after it is driven. The second jaw of said pair includes contact surfaces adapted to force a spike into the cradle of the first jaw and hold it down until said spike is driven into the tie.
