Abstract
An apparatus for salvaging nailed boards employed in the building of temporary board roads over marsh land. The boards have nails extending from one side thereof which must be bent flush and the boards stacked in bundles for reuse in laying a new board road. The apparatus has at its front end a set of board receiving rolls with their axes along the major axis of the machine for receiving the boards with their major axis transversely of the machine on the rolls with the nail extending upwardly. Co-extensive with the board receiving rolls for advancing the boards edgewise from the front to the rear of the machine are pivoted dog pushers. In advance of the nail bending roll there is provided a pair of barriers for maintaining a single vertical layer of boards. A pair of endless chains are positioned to engage and move boards edgewise rearwardly from the board receiving rolls through the machine. A single large rotary nail bending roll is positioned diagonally across the machine with its rotary axis extending across at least four boards simultaneously is positioned rearwardly of the barriers. A board transfer rod is positioned to receive a group of edgewise boards from the endless chain drive for moving the boards rearwardly of the machine to a board stacking device positioned rearwardly of the nail bending rolls for receiving the boards from the transfer rods to stack the boards for reuse.
