  • Patent number: 8471160
    Abstract: An inline conduit switch includes a body having an anchor fitting adapted for mounting to a support and a conduit fitting adapted for mounting a control cable thereto. The conduit fitting is at least partially received in a bore of the anchor fitting for relative axial movement between a first configuration to which the body is normally biased and a second, compressed configuration. First and second electrical contacts are operatively carried by the anchor fitting and the conduit fitting, and are brought into electrically conductive engagement in the second configuration. The inline conduit switch operates to create electrical contact when a control cable is placed in tension, thereby axially shifting the conduit fitting relative to the anchor fitting.

  • Patent number: 5407251
    Abstract: A tailgate assembly is disclosed for use with a dump truck which has a bed, two side walls and a bed opening, and also has an obstruction, such as a tag wheel assembly, spaced relatively closely to the bed opening. The assembly comprises a tailgate pivotally connected to hydraulically operated arms for moving the tailgate between open and closed positions. Guides restrict the tailgate to a first substantially rectilinear path of travel and lost-motion connections prevent relative pivoting of the tailgate with respect to the arms to cause outward swinging of the tailgate with respect to the truck bed during a second path of movement to prevent interference between the tailgate and the obstruction during sequential opening of the bed and the raising of the bed to its dumping position.
