  • Patent number: 7926426
    Abstract: A railway vehicle recovers metallic objects like railroad spikes from a railway bed having a pair of rails. The vehicle includes wheels for riding on each rail and a carriage carrying a crawler for supporting the vehicle on the railway bed when one of the rails is removed. A pneumatic lift raises and lowers the carriage and crawler. A conveyor belt assembly for transporting the metallic objects to a hopper is supported entirely by an overhead support structure. A lateral translator moves the conveyor belt assembly from side to side. Various features are provided which allow a conveyor belt to be removed from one side of the conveyor belt assembly while maintaining continuity of the conveyor belt loop. A distinctive conveyor lift is provided for raising and lowering the conveyor belt assembly. A remote control is provided for controlling various operations of the vehicle.

  • Patent number: 7244089
    Abstract: A machine which travels on railroad rails includes a conveyor belt which transports metallic objects from a railway bed into a hopper. The conveyor belt revolves around a pair of rollers mounted on the framework of a conveyor belt assembly. One roller magnetically picks up the metallic objects and a hydraulic motor powers the other roller to drive the conveyor belt. The magnetized roller is mounted via two mounting bearings which slidably engage the assembly. An adjustment bolt on the assembly engages the mounting bearing to move the magnetized roller to adjust conveyor belt tension to facilitate replacement of the belt. A lift beside the assembly raises and lowers one end of the assembly which rotates about a pivot tube within the conveyor belt. The lift, pivot tube and hydraulic lines connected to the motor are all situated to allow the belt to be removed without interference therefrom.

  • Patent number: 6622849
    Abstract: An apparatus and method is provided for feeding bulk metal objects from a hopper supported by a frame. The hopper includes side panels that taper downwardly to form an interior chamber therebetween with upper and lower openings. Doors are hingedly attached to the side panels adjacent the lower opening and are opened and closed by piston and cylinder combinations pivotally attached to the frame and pivotally attached to members extending downwardly from the doors. Arms extend from the doors into the interior chamber to facilitate the movement of the metal objects in the hopper toward the lower opening to feed through the doors. Vibrations created by various movements of the doors also help move the metal objects toward the lower opening.
