Plural Pivotal Axes Patents (Class 227/42)
  • Patent number: 4513900
    Abstract: An end plating machine comprising a frame having an in-feed portion at one side thereof and an out-feed portion at the other side thereof. A stationary platen is provided at opposite ends of the frame below the in-feed and out-feed portions adapted to support the ends of a cross-tie delivered thereto. A conveyor delivers the cross-ties to the in-feed portion whereupon a tie transporter assembly moves the tie from the in-feed portion and delivers the tie to a tie elevator assembly which lowers the tie onto the stationary platens. A robotic claw assembly is provided above the stationary platen for squeezing the ends of the tie to close cracks therein. Each pair of robotic claws is operated by a single hydraulic cylinder. When the ends of the tie are squeezed together by the robotic claws, a hydraulic ram at opposite ends of the tie drives nail plates into the ends of the tie.
