摘要： A constant contact side bearing assembly for a railcar including a housing with wall structure defining a central axis for the side bearing assembly and a multipiece cap. The cap is arranged in operable combination with the housing and includes a movable first member and a movable second member carried by the first member. A portion of the second member extends beyond the housing and defines a friction surface for the cap. A spring resiliently urges the friction surface of the cap into frictional contact with railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on the first member and wall structure on the second member into frictional engagement with the wall structure on said housing in response to a vertical load acting on the friction contacting surface on the cap.

摘要： An elastomeric spring including an elongated elastomeric body defining a longitudinal axis for the spring and having first and second longitudinal ends. An outer surface of the elastomeric body extends between the first and second ends and has four generally planar sides, with each planar side of the outer surface being disposed to one side of and generally parallel to the longitudinal axis of the spring so as to reduce radial bulging of the spring in all directions when an axial load is applied to the spring. The outer surface of the elastomeric body further includes four angled corner sections extending between the first and second ends of the elastomeric body and disposed a substantially common distance from the longitudinal axis of the spring. One corner section is disposed between any two adjoining sides on the outer surface of the elastomeric body.

摘要： An apparatus for releasably holding an electronic media device having a generally flat screen on which an image can be electronically displayed. In one form, such apparatus includes a base including hinged first segment and a second segments whereby allowing the base segments to be adjustably positioned and held in selected angular positions relative to each other so as to substantially reduce an operative length of the base and facilitate storage and transportation of the apparatus. The first segment of the apparatus includes structure for suspending the base from a support. The second segment of the apparatus includes structure for receiving, releasably holding and stabilizing the electronic media device with the generally flat screen of such device facing away from the front of the base.

摘要： A constant contact side bearing assembly configured for insertion into a walled receptacle provided on an upper surface of a railcar bolster. The side bearing assembly includes a housing assembly including a base and cap receivable within the open top walled receptacle on the bolster. The base has laterally spaced sides and longitudinally spaced ends. The cap is guided for movements relative to the base and has a generally flat railcar body engaging portion along with structure which combines with the sides and ends on the base to define an internal void for the side bearing assembly. A longitudinally elongated and generally rectangularly-shaped elastomeric compression spring is arranged in the internal void within the side bearing assembly for absorbing, dissipating, and returning energy imparted to the side bearing assembly during a work cycle. During a side bearing assembly work cycle, the spring is configured to deform in a predetermined manner and such that, upon maximum spring deformation, the spring maintains an operable relationship relative to the housing assembly of the side bearing assembly.

摘要： A constant contact side bearing assembly for a railcar including a housing with wall structure defining a central axis for the side bearing assembly and a multipiece cap. The cap is arranged in operable combination with the housing and includes a movable first member or spring seat and a movable second member or top cap carried by the first member. A spring resiliently urges the cap members toward railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on the first member and wall structure on the second member into frictional engagement with the wall structure on the housing in response to a vertical load acting on the friction contacting surface on the cap. At least the top cap is structured to establish a coefficient of friction ranging between about 0.4 and about 0.9 with the railcar during operation of the side bearing assembly.
