  • Patent number: 4427330
    Abstract: An upright fence picket workpiece bundle receiving frame is disposed in lateral parallel relation with respect to an upright elongated fence picket pointing machine and connected thereto by a horizontal frame extending between the upper limits of the bundle frame and picket pointing machine. The bundle frame includes a motor operated platform receiving and elevating a horizontal layered bundle of fence picket workpieces with the workpieces parallel with the length of the picket pointing machine. Workpiece layer operated cams and lifters, mounted on the bundle frame, aligns respective end portions of the uppermost layer of the workpiece bundle and lifts the topmost layer thereof to a horizontal plane spaced above the remaining workpiece bundle and the horizontal frame. Motor operated drag chains, overlying the horizontal frame and projecting into the workpiece bundle frame, move the lifted workpiece layer to an overlying position on the horizontal frame.

  • Patent number: 4387751
    Abstract: An elongated upright open framework defines a vertical workpiece passageway intermediate the frame sides and ends open toward one end of the frame bottom portion for horizontally receiving workpieces from a laterally disposed feed conveyor. The frame supports a carriage for reciprocation between its ends which is driven by a drive motor and a drive train. Pairs of clamp jaws, disposed at respective end portions of the carriage, are opened and closed by carriage movement to grip and release the respective workpiece end portions as it travels with the carriage. One pair of clamp jaws is moved by cam rollers following a cam groove on inner surfaces of the frame to contact one end portion of the workpiece with rotary cutters disposed above and below the travel path of the carriage as the carriage moves to a workpiece release position. A drive motor operated conveyor discharges the finished workpiece from the frame.
