Claims
- 1. A shear resistant roll restraining means for arresting lateral rolling motion of a railway car having a truck including a transverse truck bolster beam, a transverse car bolster beam having divergent laterally and upwardly sloping bottom web sections, and a center bearing means pivotally coupling and supporting the car bolster on the truck bolster, the improvement comprising:
- a side bearing means upstanding from the truck bolster and being laterally spaced from said center bearing means,
- a wear plate assembly on said car bolster vertically aligned with and abuttably engageable with said side bearing means,
- said wear plate assembly including an alignment wedge depending from said web section and having an upper surface portion generally conforming thereto and a substantially horizontal bottom abutment surface,
- said wear plate assembly also including a horizontally extending wear plate supported below said bottom abutment surface,
- means defining vertically extending and aligned openings in said wear plate, said wedge and said web section,
- fastening means removably positioned within said vertically aligned openings and securing said wear plate to said wedge in vertical load transfer relation, and
- weld attachment means extending substantially about the periphery of said upper surface portion of said wedge and integrally uniting said wedge and said web section independently of said fastening means, thereby to eliminate bending of said fastening means due to shearing action between said wedge and said upwardly inclined web section when said horizontal bottom abutment surface of said wedge engages said side bearing means.
- 2. The invention according to claim 1, and
- vertical shimming means sandwiched between said wear plate and wedge.
- 3. The invention according to claim 2, and
- said shimming means comprising at least one flat plate having said fastening means extending therethrough.
- 4. The invention according to claim 1, and
- a bevel washer carried on the upper surface of said web section, and a weldment integrally securing said washer to said web.
