Patent number: 6550394Abstract: An auxiliary suspension for hydraulic or pneumatic railway car suspensions is disclosed. The auxiliary suspension includes a bumper assembly which is located below the railcar body. The bumper assembly further includes a bumper pad that is retracted when a certain level of pressure is present in the hydraulic or pneumatic suspension. In a retracted position, the passenger car has room to “kneel” at a station platform to align the car floor height with the station platform height. When pressure in the hydraulic or pneumatic suspension is absent, the bumper pad of the auxiliary suspension extends to allow safe operation of the passenger train.Type: GrantFiled: March 11, 2002Date of Patent: April 22, 2003Assignee: Buckeye Steel Castings CompanyInventor: Richard B. Polley

Patent number: 6546877Abstract: A load weigh valve assembly for a railway car is provided. The load weigh valve assembly is mounted to the truck frame on primary sprung trucks to enable actuation of the load weigh valve pivot arm. The load weigh valve assembly is also mounted to the truck frame so as to eliminate the problems associated with oscillating and sliding motion at the load weigh valve pivot arm. In addition, the undesirable valve actuation that occurs due to car roll is eliminated.Type: GrantFiled: December 19, 2001Date of Patent: April 15, 2003Assignee: Buckeye Steel Castings CompanyInventor: Roger F. Sanzo

Patent number: 6543367Abstract: There is disclosed a lightweight truck sideframe for use in a railway car. The truck sideframe is of lighter weight than conventional truck sideframes because of the removal of the double wall of the truck sideframe tension member, leaving a single wall tension member. Removal of this significant mass of metal requires reinforcement of the truck sideframe in several areas including in the tension member below the spring seat, in the compression member, and at the side wall window. The resulting truck sideframe construction is of lighter weight than conventional truck sideframes and exceeds the Association of American Railroad's requirements for strength and durability.Type: GrantFiled: November 14, 2000Date of Patent: April 8, 2003Assignee: Buckeye Steel Castings CompanyInventors: Todd W. Stecker, Richard B. Polley, Roger D. Boster, II

Publication number: 20030047247Abstract: A high strength steel alloy for use in manufacturing railway car components. The alloy has a chemical composition that meets the industry required specifications for B grade steel and exhibits better mechanical properties, such as higher yield and tensile strengths. Secondary benefits of the inventive steel alloy include enhanced weldability and improved fatigue resistance.Type: ApplicationFiled: May 29, 2002Publication date: March 13, 2003Applicant: Buckeye Steel Castings CompanyInventor: Bruce A.

Patent number: 6354226Abstract: There is disclosed a light weight truck bolster for railway car trucks. Metal has been removed in the compression and tension members of the bolster near the center bowl. One longitudinal rib is located in each end of the bolster arms and a pair of transversely extending vertical ribs are located on opposing sides of the center bowl and extend from the tension member to the compression member. The disclosed light weight truck bolster satisfies the Association of American Railroads (“A.A.R.”) design qualifications for truck bolsters while weighing significantly less than traditional truck bolsters.Type: GrantFiled: March 1, 2001Date of Patent: March 12, 2002Assignee: Buckeye Steel Castings CompanyInventor: Todd W.

Patent number: 6079335Abstract: There is an electric railway truck comprising an unsprung third rail collector beam for a swing arm primary suspension. The collector beam and attached current collector is mounted to the truck frame through the use of mounting adapters, links, and elastomeric bushings. Specifically, in the vicinity of the swing arm axle housings, the collector beam is secured to the mounting adapters which, in turn, are suspended below the respective axle housings by the links and accompanying elastomeric bushings. The torsional deflection of the elastomeric bushings permit the links to swing in the longitudinal direction, thereby accommodating the relatively larger angular and longitudinal axle housing motions created by a swing arm primary suspension.Type: GrantFiled: February 23, 1999Date of Patent: June 27, 2000Assignee: Buckeye Steel Castings CompanyInventor: Richard B. Polley

Patent number: 6053112Abstract: There is disclosed a method for compensating for wheel wear to maintain a constant car floor height above the railroad track where the compensating shim is at all times attached to the railway truck. The method comprises generally the steps of providing a wheel wear compensating shim that, when not being used, is removably attached to the underside of the bearing housing or other suitable location, lifting of the side frame away from the primary suspension, disposing the compensating shim between the side frame and the primary suspension, and finally lowering the side frame back onto the shim and primary suspension. The railway truck can thus be shimmed for wheel wear at any location where the side frame and accompanying car body can be lifted without the need to take the railcar to a retrofit service shop.Type: GrantFiled: December 7, 1998Date of Patent: April 25, 2000Assignee: Buckeye Steel Castings CompanyInventor: William C. Jones, Jr.

Patent number: 5967349Abstract: A coupler is provided for a railroad rotary dump car. The coupler comprises a coupler housing, a coupler head, a buff loading shim, and as most preferred, a plurality of spring tabs, and spring tab fasteners. The coupler housing defines a coupler cavity with a cavity end. The coupler head has a spindle, is mounted to the coupler housing, and is adapted for rotary movement relative to the housing. The spindle has a spindle end adjacent the cavity end. The shim interposes the spindle end and the cavity end. The spring tabs are spaced one from another. Each includes a spring portion and a fastener portion. The fastener portions provide for removable fastening of the spring tabs to the coupler housing. The spring portions bias the shim against the cavity end and away from the spring tabs. The spring portions are curved relative to the fastener portions. The spring tab fasteners removably fasten the spring tabs along the fastener portions to the coupler housing adjacent the shim.Type: GrantFiled: March 9, 1998Date of Patent: October 19, 1999Assignee: Buckeye Steel Castings CompanyInventor: Rodney A. Engelbrecht

Patent number: 5762003Abstract: A railroad hopper car for carrying loads of commodities comprises spaced trucks and a car body supported on the spaced trucks. The car body includes an underframe having a center sill, with discharge openings, the center sill in the area of the discharge openings toward the loaded commodities having surfaces sloped toward the discharge openings. The underframe has members connecting the car body to the spaced trucks. These members have shapes distinct from the shape of the center sill. The car body further includes transition members between the center sill and underframe members connecting the car body to the spaced trucks. The transition members along the center sill are sized and shaped to fit with the center sill, and the transition members along the underframe members are sized and shaped to fit with the underframe members. The transition members transition between the center sill and underframe members, allowing the center sill to have sloped surfaces while the underframe members have other shapes.Type: GrantFiled: February 24, 1997Date of Patent: June 9, 1998Assignee: Buckeye Steel Castings CompanyInventors: John R. Downes, Carl D. McClurg

Patent number: 5005715Abstract: An articulated connector for railroad cars comprises first and second connector members pivotally connected to each other at inner ends through a pin to permit vertical, rotational and horizontal pivoting of the connector members. The connector members have opposed ends proportioned to each welded to a railroad car sill. The articulated connector may be attached to a railroad truck which holds the connector and the ends of both connected cars. Pin bearing block means are carried in the articulated connector and abut the pin. Preferably, slack adjusting wedges are used to urge the pin against the pin bearing block, with the slack adjusting wedge means being laterally positioned in the connector. Side apertures are then provided for access from the exterior to the slack adjusting wedge means.Type: GrantFiled: July 24, 1989Date of Patent: April 9, 1991Assignee: Buckeye Steel Castings CompanyInventor: James E.
