Abstract: A friction dampener can include a housing having one end slidably surrounding one end of a shaft movable relative thereto. Opposing ends of the housing and shaft can each having a connecting eye member for connection to separate independently movable elements. One or more friction elements can be carried by the shaft which frictionally engage inner surfaces of the housing. The friction elements can have inner and outer portions having different material properties. The housing can be adapted to generally maintain the pressure between the friction elements and the housing within a range of desirable pressures.

Abstract: A railway vehicle truck having side frames which are supported with respect to the journals of spaced apart wheelsets with the respective pair of wheelset axle ends supporting each side frame being constrained to move simultaneously in opposite directions toward and away from each other in response to truck steering impulses.

Abstract: An articulated connector for flexibly connecting the adjacent ends of a pair of rail car platforms which are supported on a common truck bolster, the connector comprising a spherical bearing formed integrally with a conventional center plate bearing of one car platform, and spherical elements carried by the other car platform for cooperable engagement with the spherical bearing to transmit vertical, lateral and longitudinal train forces between the adjacent platforms solely through engagement of the mating spherical bearing elements.

Abstract: A railway truck and a bearing adapter therefor which provides improved control of relative movement between a railway truck wheelset and the truck side frames supported thereby.

Abstract: A railway truck and more particularly a truck including a variable bias bolster friction assembly having an elongated retention spring which extends preferably between a side frame spring seat and an inner end portion of a downwardly opening spring pocket formed in a rigid friction shoe, the spring pocket extending upwardly therein to provide space for a maximum length retention spring in a variable bias friction assembly.

Abstract: An articulated rail car connector for joining the adjacent ends of rail car platforms which are supported on a common truck bolster, the connector including in one preferred embodiment a pair of nested center plates which support the adjacent car platforms upon such a truck bolster and which are longitudinally slideable with respect to one another, and a drawbar pivotally connected between the adjacent car platforms to transmit longitudinally directed buff and draft loads therebetween.

Abstract: A hydraulic snubber device and more particularly, a snubber adapted to be interposed in the spring group between a bolster and a side frame member and having a single primary operating cartridge which is selectively usable with a plurality of differing configuration snubber casings or envelopes for a variety of spring group positions; and, further, a snubber device which is operationally positionable within the center of a spring group and is captively retained therein solely by communication of the snubber casing thereof with laterally adjacent springs of such a spring group.

Abstract: A railway truck assembly provides sprung support of a car body with respect to the truck wheels by means of compression springs interposed between axle carried supports such as truck side frames and a car body support such as a bolster, wherein biased friction assemblies provide fit-up and friction damping of relative motion between the axle carried supports and the car body support, the friction assemblies including rigid metallic friction members and elastomeric elements received in a pocket formed by spaced surfaces which engage the respective members with the elastomeric elements in biased engagement with a pocket surface and having an elastic characteristic to provide an elastomeric response for non-rigid compliance and cushioning of low level car body support force variation through elastic deformation thereof, and damping of larger level car body support force variation through bodily sliding of the friction wedges on frictionally engaged surfaces in repeatable cycles of elastomeric cushioning, frictio
