  • Patent number: 4562775
    Abstract: A railway vehicle, in particular a locomotive, has three or more trucks with the bolsters of each swivelly supported on the respective truck frames and having means for transmitting longitudinal traction and braking forces to the body underframe. The truck bolsters mount upright body-support spring devices which are yieldable in shear transversely of the locomotive to permit sufficient limited lateral movement of the body with respect to the trucks to prevent the full force of lateral blows and shocks received by the wheels from being communicated to the body and for preventing the momentum of the body from acting with its full lateral force on the truck wheels and rails.

  • Patent number: 4494412
    Abstract: A testing tool for studs and similarly mounted fasteners comprises a cylinder having a base adapted to rest against the surface from which the stud protrudes and a piston axially movable in the cylinder with a hollow piston rod through which an enlarged threaded rod slidably extends, the end of the threaded rod adjacent the base having means to grip a stud when the base of the cylinder is seated against the stud-mounting surface. In one embodiment of the invention, a collar with handles is threadably mounted on the end of the externally threaded rod remote from the base abutting the adjacent end of the piston rod and a hydraulic pressure gauge is attached to the end portion of the cylinder nearest the base so that when the collar is rotated by its handles to apply tension to the stud, it forces the piston downwardly in the cylinder so that the pressure shown on the gauge is proportional to the tension applied to the stud.
