Center Bowl Liner With Spring Washer Conductor

US Patent:
8413590, Apr 9, 2013
Filed:
Dec 21, 2011
Appl. No.:
13/333323
Inventors:
James Kennedy - Zelienople PA, US
Jon Kaufman - Beaver PA, US
Assignee:
A. Stucki Co. - Moon Township PA
International Classification:
B61F 3/00
US Classification:
1051994, 384422
Abstract:
A center bowl liner provided for use between a center plate of a railroad car and a center bowl surface on a truck bolster. The center bowl liner includes a disc-shaped element having top and bottom surfaces and a central opening for receiving a center pin. A conductive washer is attached to the disc-shaped element, the conductive washer having a profile wherein portions of the conductive washer are exposed at the top and bottom surfaces of the disc-shaped element and create an electrical connection between the railroad car center plate and the center bowl on the truck bolster. The disc-shaped element acts as a load-bearing element supporting the railroad car center plate. The conductive washer, since it may have spring-like properties, will also undertake to bear a limited amount of the load of the railroad car center plate in addition to providing electrical connection between the car and truck.

Abstract:
A center bowl liner is provided for use between a center plate of a railroad car and a center bowl surface on a truck bolster. The center bowl liner includes a disc-shaped element having top and bottom surfaces and a central opening for receiving a center pin. A conductive spring washer is attached to the disc-shaped element, with the conductive spring washer having a contoured profile such that portions of the conductive spring washer are exposed at the top and bottom surfaces of the disc-shaped element and create an electrical connection between the railroad car center plate and the center bowl on the truck bolster. The disc-shaped element acts as a load-bearing element generally supporting the railroad car center plate. The conductive spring washer, since it has spring-like properties, will also undertake to bear a limited amount of the load of the railroad car center plate in addition to providing an electrical connection between the car and truck.
