  • Patent number: 4861195
    Abstract: A cable guiding chute assembly suitable for attachment to a vibratory plow blade to dispense a cable at a selected drop radius. The cable chute assembly includes a pair of generally vertical side wall members joined by a forward wall to define a cable passageway and interchangeable gate members extending the length of the passageway to define cable guiding conduits having different radii. Each gate member is releasably secured to the side walls of the chute to permit expeditious removal and replacement. Further, the chute assembly is constructed with minimal surface area to reduce drag and a leading edge to reduce the build-up of material between the chute and plow blade. Moreoever, the chute assembly includes a downwardly directed bottom opening which permits pulling of the cable when the plow blade is removed from the ground without damaging the cable exterior.
