Patent number: 4917019Abstract: A railway car comprises a center sill with a crossbearer, webs and end bolsters extending across thereof. A light side stiffener interconnects the projecting ends of said webs and spans between the bolster and the crossbearer. A shear plate covers a trapezoidal end frame extending from the bolster. The frame includes inclined braces buttressing a pair of cantilivered brackets projecting toward and horizontally overlapping similar brackets of the adjacent car.Type: GrantFiled: May 12, 1989Date of Patent: April 17, 1990Assignee: Trinity Industries, Inc.Inventors: Harold E. Hesch, Phillip G. Przybylinski, Robert P. Sellberg

Patent number: 4893568Abstract: A hopper car is converted to a gondola-type car by replacing the hoppers and their dump doors with a light metal sheet floor. The floor sheets form a series of box-like compartments. The compartments are formed by crossbearer partitions extending between the side walls, center sill and the sheet floor. Floor frame members reinforce the rigidity of the floor structure. The partitions are formed by tubular crossbearers on gussets on the center sill, and closure walls converging at the top thereof.Type: GrantFiled: December 7, 1987Date of Patent: January 16, 1990Assignee: Trinity Industries, Inc.Inventor: Norman S. Adams

Patent number: 4817537Abstract: A container carrying rail-highway vehicle in the form of a semitrailer chassis including an elongated center sill box extending longitudinally of the vehicle, a front box-type transverse sill attached to a forward portion of the center sill and a rear box-type transverse sill attached to a rearward portion of the center sill member. Two side beams are further provided and are attached at each end thereof to the front sill and rear sill, respectively, on either side of the center sill. The side beams are disposed from a generally higher position in the front of the vehicle to a lower level at the rear of the vehicle and are further attached to the center sill by a plurality of transverse outrigger members which extend between the center sill and each of the side beams.Type: GrantFiled: March 16, 1987Date of Patent: April 4, 1989Inventors: Alan R. Cripe, Christopher A. Cripe

Patent number: 4802420Abstract: This invention relates to centre beam freight cars. The purpose of these freight cars is to carry large, bulky freight which does not require much protection from the elements. Thus, any freight car must have wide utility and sufficient rigidity but a tare mass which does not constitute a high proportion of the fully laden mass of the freight car. The prior art freight cars suffer from a high tare mass proportion in order to provide sufficient rigidity. In this invention, a freight car is provided with a centre beam structure in the form of a vertical truss having a horizontal truss mounted on the top of it. Either of the trusses, or both, are in the form of an open truss. This centre beam structure provides a freight car which has adequate resistance to normal lateral and compressive stresses but has a relatively low tare mass in relation to its fully laden mass.Type: GrantFiled: July 21, 1987Date of Patent: February 7, 1989Assignee: National Steel Car LimitedInventors: Ronald S. Butcher, Mohamed A. Khattab

Patent number: 4690072Abstract: A railway car body structural arrangement has a bolster fabricated from plates and formed on the upper surface of a bottom closure member of the body of a railway car and rigidly affixed to a bolster post at each side of the car. The lower portions of the bolster posts are affixed to the bolster assembly adjacent to the upper surface of the bottom closure member to enable use of a continuous side sill member on the car. Bearing surfaces which limit the transverse angular movement or roll of the car body with respect to a truck are attached to and project downward from a lower surface of the frame of the truck which is supportingly and pivotally engaged with the center sill substantially directly beneath the bolster.Type: GrantFiled: April 5, 1984Date of Patent: September 1, 1987Assignee: Pullman Standard Inc.Inventors: Herbert S. Wille, Phillip G. Przybylinski, Joe B. Raidt
