  • Patent number: 6749380
    Abstract: A mechanism to assist in raising and lowering a hinged deck end section wherein a lifting force is applied to the deck end section by a counterweight mechanism. In the preferred embodiment, the counterweight mechanism operates in conjunction with a conventional, proven spring assist mechanism of the type that has been used in the past on trilevel railway cars. The counterweight mechanism preferably includes a counterweight that is slidable along a vertical track in a location that is readily accessible for visual inspection and maintenance. Nonmetallic wear pads are preferably employed in conjunction with a dry film lubricant to control friction between the counterweight and the track. The mechanism preferably provides a mechanical advantage so that the lifting force applied by the counterweight mechanism exceeds the weight of the counterweight. A roller chain, steel cable, or the like is preferably employed to connect the weight to the deck end section.

  • Publication number: 20020127078
    Abstract: A door edge protection assembly for installation on a railcar. The railcar has a side wall, a roof rail running substantially horizontally along the top of the side wall, a roof extending upwardly and inwardly from the roof rail, and a plurality of decks for supporting vehicles thereon. The door edge protection assembly includes a door edge protection member for cushioning impacts between a vehicle door edge and at least one of the side wall, the roof rail, and the roof. In the preferred embodiment, the door edge protection assembly also includes a clip for supporting the deformable door edge protection member in the interior of the railcar. The clip lockingly engages the roof to provide positional stability of the deformable door edge protection member relative to the roof rail and roof.

  • Patent number: 6339994
    Abstract: A radial end door that includes, in addition to the conventional inner and outer rollers for supporting the door, a door mounted support on the inner portion of the door, unsupported by the railcar body when the door is open, but supported by the railcar body when the door is closed. The door mounted support preferably comprises a roller that can be added as a retrofit or upgrade to the existing door, without altering the basic configuration, geometry or operational characteristics of the door, except to improve the performance of the door. The door mounted support preferably cooperates with a floor-mounted support comprising a wear bar having a ramp portion to raise the door mounted support and increase loading on the outer roller as the door is closed.

  • Publication number: 20010035108
    Abstract: A novel sidewall structure for a motor-vehicle carrying railway car wherein at least one upper deck is supported principally by longitudinal beams that are themselves supported by end structures, without the need for large, heavy vertical posts to support the decks between the end structures. To provide a lightweight car body with sufficient strength and durability for commercial rail service, the car body may be of monocoque construction. Each sidewall preferably has a plate girder structure that employs the horizontal beams as its principal supports, with the beams tied together by sidewall panels or plates. A plurality of light stiffeners may be employed to limit flexure of the sidewalls. Each of the end structures preferably comprises an offset H frame that includes a draft sill joined to a body bolster, and inner and outer cross bearers joined to the draft sill. In the offset H frame, the draft sill slopes downward and inward, with the inner cross bearer being at a lower elevation than the outer one.

  • Patent number: 6024023
    Abstract: A railway hopper car comprises one or more gates, which have a durable, abrasion-resistant, low-friction coating applied to the upper, load-contacting surface thereof to reduce breakaway opening torque. The railway hopper car is particularly useful in handling heavy loads of bulk materials which have high densities and which compact under load, such as soya meal and hydrated alumina. The preferred coating use on the gate is a polymeric powder paint coating having high impact resistance, as well as high abrasion resistance, at the temperature extremes that may be experienced in the harsh operating environments typically encountered by railway hopper cars. The preferred coating is a food grade material suitable for use in contact with bulk agricultural commodities.

  • Patent number: 5829360
    Abstract: An auto rack car has an improved door locking mechanism for heightened security in auto rack car doors which rely on upper and lower lock assemblies for security. The improved locking mechanism is lightweight and inexpensive and is adaptable for retrofit installation to lock assemblies which are currently in use on auto rack cars. The locking mechanism thus provides a commercially viable means to prevent unauthorized intrusions into the car involving unlocking of an upper lock assembly and subsequent flexure of the door while a lower lock assembly remains locked.

  • Patent number: 5787816
    Abstract: A novel method and apparatus for installing and securing auto rack side panels, either during manufacture of the auto rack railway car, or during refurbishment of the car, where covers are placed over components which clamp the panel corners. In a preferred embodiment of the invention wherein end portions of elongated dust closure plates are employed to clamp side panel corners against brackets to prevent metal-to-metal contact between the end portions of the dust closure plates and the side panel corners engaged by the end portions thereof, plate covers are installed over the end portions of the elongated dust closure plates so as to be disposed between the end portions of the dust cover plates and the panel corners, to avoid abrasion and rusting as a result of friction.

  • Patent number: 5782187
    Abstract: A pivot plate assembly for supporting vehicles over the articulation between pivotably interconnected railway car units, and allowing rolling transport of vehicles from one railway car unit to the next. Platforms are pivotably attached to respective railway car units adjacent their interconnected ends. A vehicle has its front end portion secured to one of the pivotal platforms and its rear end portion secured to the other platform while the platforms are oriented collinearly with respect to one another. The vehicle thereby maintains the pivotal platforms collinear with one another as the railway car units pivot with respect to one another. Accordingly, the pivotal platforms remain substantially stationary with respect to the vehicle supported thereon throughout pivotal movement of the railway car units to stably support the vehicle straddling the articulation between pivotably interconnected railway car units during transport.

  • Patent number: 5575221
    Abstract: A truck mounted brake system comprising a brake cylinder mounted on a truck bolster, having a cylinder rod extending through the bolster, wherein a series of elongated slots are provided in the second sidewall and the intermediate webs of the bolster to facilitate access to mounting bolts for the brake cylinder. The slots are dimensioned to avoid unnecessary weakening of the bolster. In the preferred embodiment, the brake cylinder is positioned so that the pivot point at which the cylinder rod joins the brake lever is substantially coaxial with the brake cylinder bushing when the cylinder rod is in its extended, loaded position. Interior and exterior surfaces of the bolster sidewall which the brake cylinder and its associated fasteners engage are preferably substantially planar to avoid loosening of the fasteners over time due to surface irregularities.
