  • Patent number: 4407203
    Abstract: A lift lug for receiving and securing a lifting device to a railroad tank car for re-railing the tank car. The lift lug includes a bolster pad mounted adjacent an end of the tank car and a vertically disposed bolster web, the bolster web having a substantially horizontal extending upper edge. A substantially horizontal base plate is mounted on the extended upper edge of the bolster web with an inner edge of the horizontal base plate secured to the bolster pad. A substantially vertical lift lug plate has its upper edge secured to the bolster pad and its lower edge secured to the base plate. A pair of generally triangular lift lug webs each have their lower edges secured to the base plate, their outer edge secured to the bolster pad. The lift lug plate has an opening adjacent its lower edge.

  • Patent number: 4406152
    Abstract: A railroad tank car is calibrated by continuously adding liquid into the tank car from a liquid supply means. The amount of liquid is measured by meter means as the liquid is being continuously added. Depth sensor means continuously determines the depth of liquid in the tank car. A computer is used to monitor the instruments and to obtain a measure of the volume of liquid in the tank car at pre-determined depths and to correlate the volume measure with the measured depth.

  • Patent number: 4275662
    Abstract: A roof structure for covered hopper cars has roof sheets with curved sections disposed on each side of a continuous trough hatch opening. A hollow, beam-type side plate connects the outer margins of the roof sheets to the side wall unit and includes an outer transition member with a curved section forming part of the side plate and also having a lip extending inwardly of the vehicle to form a continuation of the curved roof sheet. A connection piece underlies transversely extending edges of the roof sheets to join the sheets. Intermediate bulkheads or partition sheets have a rounded top to fit snugly for attachment to the curved roof sheets and are rigidified by stiffeners which extend horizontally and transversely of the vehicle from side plate to side plate and are connected thereto to join with the roof sheets and intermediate bulkheads to form a rigid roof beam which resists twisting and deflecting during transit.
