ABSTRACT:
Apparatus for securing pickets to elongated stringers employs a worktable having stringer accomodating channels into which the elongated stringers are placed. A picket hopper accomodates a stacked array of pickets transverse to said channels and stringers. A reciprocating carriage assembly is positioned on the worktable and reciprocates a given distance in a forward and backward movement. As the carriage moves forward the lower most picket in said hopper is pushed to a fastening location. Located at this location and above the pushed picket are fastening means, which are air actuated nailing guns. The guns are mounted on a shaft which is synchronized with the carriage assembly to cause the guns to move about an arcuate path which causes the guns to contact the picket at the fastening location to secure the same to the stringers. Also including are side locking means which are located in the stringer channels and which force the stringers against the vertical channel walls during carriage motion to provide a consistent product. The operation is automatic and each successive picket is secured to the stringers by the carriage pushing the next picket against the last picket nailed. In this manner the carriage assembly pushes the completed product away from the fastening location at increments equal to the picket width and this action occurs for a picket of any width. The action of the apparatus further assures that each picket is straightened or aligned with the last secured picket due to the forces exerted on the pickets by the carriage assembly. Other features as synchronizing means for the entire operation are described.
