ABSTRACT:
A pair of air-operated hammers for driving railroad spikes are guided by separate yokes, raised and lowered by trunnion-mounted cylinders; a cross frame in a vertical plane is supported between the hammers and clamps join upright guides to the crossframe, the clamps enabling the hammers to be laterally adjusted on a main frame.
