Abstract
Abstract Apparatus for forming stakes, bridging and the like from new or scrap material particularly from pieces of material of similar but varying cross-sectional dimensions. The apparatus includes a conveyor means having a plurality of laterally disposed pockets longitudinally spaced therealong, three saws one of which is disposed along one side of the conveyor means and the remaining saws being disposed along the other side of the conveyor means, means for securely holding within each pocket during the sawing operation the pieces of material to be disposed therein to prevent vertical movement thereof relative to the saws, shield means disposed in partial encompassing engagement about said pocket as same pass adjacent to saws and about said saws, and means for driving the conveyor means and the saws. Each of the pockets has opposed wall means for limiting longitudinal movement of the pieces of material to be disposed therein relative to the conveyor means. Each of the saws is mounted for pivotal movement about a corresponding line disposed parallel to the longitudinal axis of the conveyor means. The driving means includes a separate electric motor for each saw, each saw being mounted upon the shaft of its corresponding motor. A fourth saw may also be mounted along the other side of said conveyor means. An apparatus for forming stakes is obtained by using a guide rail in lieu of a saw along said one side. An apparatus for forming bridging is obtained by using one saw on each side of said conveyor means.
