Abstract: An internal combustion engine overspeed protection system utilizes a spring-actuated expandable overspeed link in the fuel control linkage to shut off fuel independently of governor or throttle action. The link is normally latched in a contracted condition and positioned in the fuel linkage between a manual fuel lever and the fuel cranks for the respective cylinders of the engine. An automatically resetable hydraulic actuating device unlatches the link in high speed response to an engine overspeed condition. A spring coupling in the fuel linkage permits relatching of the overspeed link by manipulation of the fuel lever.

Abstract: A portable battery cart is disclosed for transporting electrical batteries including a wheeled base frame and an elevator platform carried by the base frame. A jack lift is provided for moving the elevator platform vertically relative to the base frame. A movable frame is carried by the elevator platform and a rotatable drive assembly is provided for moving the movable frame means in a generally horizontal direction relative to the elevator platform. The elevator platform includes a plurality of rollers and the movable frame includes a latch member for attachment to the battery so that the battery moves with the frame means over the rollers for loading and unloading from a roller platform of an associated storage rack.
