  • Trolley pole support apparatus with variable length moment arm
    Patent number: 6193035
    Abstract: A trolley pole support apparatus is provided in which the trolley pole is urged to an extended position by a spring acting against a moment arm and the force required to position the trolley pole in the stowed position is minimized by minimizing the moment arm between the spring contact point and the trolley pole pivot. By doing so, even with the maximum compression of the spring in the stowed position, this small moment arm permits only small forces to be transmitted to the trolley pole shoe.

  • Rerailer apparatus
    Patent number: 5896816
    Abstract: Disclosed is a rerailer apparatus that can be installed in a rail car for rerailing the rail car if it derails. The rerailer includes two vertical lifting members which are suspended from the rail car and are connected to a foot. These lifting members are used to lift the rail car vertically when the lifting members are extended and the foot contacts a support surface. A lateral movement member integrated with the vertical lifting members and the foot is used to move the lifted rail car laterally.
