  • Publication number: 20010010198
    Abstract: A railcar unit has a pair of opposed side sills that are joined by structure that performs the function of a web in a deep beam or bracing in a truss. The joining structure is able to transmit loads that are applied transversely to the longitudinal direction of the car from one sill to the other, and is also able to transmit a bending moment couple, in the form of opposite longitudinal tensile and compressive forces, also transmitted to the side sills. The locations at which the transverse forces are imposed on, or by, the intermediate structure have longitudinal slip. When the railcar unit is placed in longitudinal tension under draft loads, the longitudinal slip allows the floor structure not to be subject to the longitudinal draft loads. In the embodiment described the joining structure serves the additional function of acting as a floor panel for vertical loads carried within the well car unit.

  • Patent number: 6263805
    Abstract: There is provided a vehicle end sill or the like, in which lap joints formed by one side lap welding are not simply deformed or broken off. An end sill 1 is formed as a box type structural body which includes lap joints W1 which are formed by one side lap welding conducted only from the outer side. Edge portions 12a and 13a of face plates 12, 13 to be superposed on the surfaces 11a and 11b of the end member (intermediate member) 11 are formed as a zigzag shape. The end member has the longitudinal axis substantially perpendicular to the direction along which the load is adapted to be applied to the end sill 1. Lap welding (one side welding conducted only from the outer side) is conducted along the edge portion 12a and 13a of the zigzag shape.

  • Patent number: 6205932
    Abstract: A railcar has a substructure, a superstructure and intermediate webwork sides joining the substructure and the superstructure to form a truss-like structure for carrying automobiles. The resultant truss-like structure does not have a straight through center sill, but does retain end stub sills. The main deck of this structure can be depressed between the railcar trucks, and, in combination with a vehicle supporting deck structure allows vehicles of a greater height to be carried in the depressed center than over the end structure above the railcar trucks. The integrated structure, including a structurally significant roof frame, is also used to support the vehicle carrying decking.

The underframe is constructed of a first corrugated plate in which the corrugations run longitudinal of the vehicle. A second corrugated plate is secured to the underside of the first mentioned plate and the plates are arranged so that the corrugation troughs of the upper plate are in longitudinal alignment with corrugation peaks of the lower plate to define a hollow core honeycomb pattern between the plates.

    Abstract: In a railway freight car an elastomeric boot is attached to the entrance and/or exit of a hollow sill or hollow structural member through which a brake rod passes. The brake rod passes through a brake rod opening in the boot in entering and/or leaving the sill or structural member, and the boot engages the brake rod sufficiently to substantially prevent moisture from passing through the boot and into the sill or structural member.

  • Patent number: 3939777
    Abstract: A mobile trackway comprises a plurality of interconnected carriages adapted for rolling on an existing trackway, and having mounted on upper surfaces thereof two side-by-side trackways. Ramp cars (which form part of the mobile trackway) and switching sections on the carriages permit load-transporting cars to be moved to either of the two trackways from the existing trackway. When used in conjunction with tunneling machinery, a string of muck cars is positioned on one of the trackways and may be conveyor loaded while previously loaded cars are removed from, and empty cars are delivered to, the other trackway. The carriages are of hollow shell construction and are adapted for carrying ballast, for example excavated rock, scrap iron or concrete, to prevent being tipped over by any arrangement of loaded muck cars thereupon. No other stabilization means, such as outriggers or supporting members contacting the tunnel, is required.
