Patent number: 7549379Abstract: A long travel constant contact side bearing for railway cars provides better handling characteristics, achieving improved tracking and curving through use of various combinations of features. The side bearing comprises a base and a generally cylindrical wall section extending upwardly from the base. A cup-shaped cap comprises a generally circular top section and a generally cylindrical wall section extending downwardly therefrom. The cap extends into the wall section of the base. At least one coil spring is provided within the base and extends to the underside of the cap. The cup shaped cap includes a centrally located cut out section with an elastomer pad fitted within the cut out section. The cup shaped cap cylindrical wall sections can be coated with a lubricant or hardening substance.Type: GrantFiled: July 19, 2006Date of Patent: June 23, 2009Assignee: AMSTED Rail Company, IncInventors: Jay Monaco, Bradford Johnstone

Patent number: 7527003Abstract: An improved side bearing for railway cars is provided that achieves improved tracking and curving by the limitation of rock of the railway car. The side bearing comprises a base with a generally upwardly extending wall portion. A cap comprising a top section with generally downwardly extending wall portion is provided. The cap extends into or around the wall section of the base. Two coil springs are provided within the base that extend to the underside and support the cap. An elastomer spring is also provided that is located within an least of one of the coil springs.Type: GrantFiled: May 21, 2008Date of Patent: May 5, 2009Assignee: ASF Keystone, Inc.Inventors: Ralph H. Schorr, Bradford Johnstone

Patent number: 5017066Abstract: An adjustable guide for a railway well car has a fixed guide for centering containers of a wide standard width during loading, and a retractable guide associated with and placed below the fixed guide for centering and positioning of containers of a narrower standard width. The positioning of the guides one below the other provides a stepped guide arrangement for incrementally guiding the container as it enters the well of the car.Type: GrantFiled: January 3, 1990Date of Patent: May 21, 1991Assignee: Trinity Industries, Inc.Inventors: Eugene R. Tylisz, Bradford Johnstone

Patent number: 4782762Abstract: A railway car train comprises five car units. Each car unit has two end structures with a depressed well portion supported therebetween. A pair of side structures extend between the end structures and adjacent the well portion. A floor structure extends between lower portions of the side structures to form the bottom of the well portion. The floor structure includes an end beam extending transversely between lower portions of the side structures at the end of the well portion. The end structure includes a stub center sill connected to a shear plate member. A deflection member is secured to the inward end of the shear plate member. The deflection member includes a vertical wall portion and a sloping wall portion for deflecting containers into the well portion as they are loaded. The deflection member is connected with the shear plate member to form a transverse girder.Type: GrantFiled: May 7, 1987Date of Patent: November 8, 1988Assignee: Trinity Industries, Inc.Inventors: Bradford Johnstone, Phillip G. Przybylinski, Eugene R. Tylisz

Patent number: 4741274Abstract: A railway hopper car has longitudinally spaced hoppers on both sides of a center sill. The hoppers have door assemblies which may be opened and closed by a door operating mechanism. The door operating mechanism includes a pneumatic cylinder which rotates a lever to move an operating rod longitudinally within the center sill. Door operating levers are rotatably supported on the railway car and pivotally connected to the operating rod to be rotated when it moves. The door operating levers are pivotally connected with struts connected with the door on the hoppers. The mechanism is configured so that all forces are substantially coplanar in a vertical plane passing through the centerline of the center sill to reduce lateral twisting forces in the mechanism. Adjustment of the length of the strut is provided for positioning of the door operating levers during assembly.Type: GrantFiled: March 27, 1986Date of Patent: May 3, 1988Assignee: Trinity IndustriesInventors: Ray L. Ferris, Bradford Johnstone, Emmanuel L. Komasinski, Maurico F. Rosellini, William D. Stoughton

Patent number: 4651650Abstract: An elastomeric pad placed in shear and having one portion or surface engaged with a portion of a railway car body and another portion or surface engaged by pivotal linkage means to a wheel housing dampens vibrations of a wheel and axle assembly which is resiliently mounted to the car body for rollingly supporting the car body. The pivotal linkage is elongated and connected to the wheel housing and the car body using spherical bearings to minimize wear. The linkage is attached at an angle of inclination to minimize strain on the elastomeric pad and linkage assembly caused by vertical travel of the railway car body due to varying weight loads.Type: GrantFiled: January 9, 1985Date of Patent: March 24, 1987Assignee: Pullman Standard Inc.Inventors: Eugene R. Tylisz, Bradford Johnstone
