  • Patent number: 5573126
    Abstract: When slack-free railcar connector assemblies are placed under very high tensile loading, the connector assembly components will stretch and allow a typical "rigid" gravity wedge to descend into a fully seated position between the components and lock-in the tensile loads. The locked-in loads become additive in nature when successively encountered compressive loads are experienced by the connector assembly, thereby increasing the lateral drawbar angling forces, as well as accelerating coupling component wear. The wedge component of the present invention includes a means for vertically supporting and retaining the wedge in a holding position slightly above the normally fully seated position during the tensile loading, thereby eliminating the build up of tensile forces in the connector assembly.

  • Patent number: 5507400
    Abstract: A slackless drawbar or coupler head rotary connection between adjacent cars of a train which is movable along a fixed trackway, is described as having a ball and socket swivel-type connection which allows the elongated shank of a drawbar or coupler head to swivel freely in any direction, contrary to existing devices which employ a cylindrical connector which rotates in a cylindrical recess, thereby allowing the shank to rotate about its longitudinal axis rather than the center of a ball-shaped connector. In the existing designs, angling is achieved by distorting the shape of the pin hole in the shank of the drawbar or coupler head. This is undesirable and causes greater wear of the shank. The swivel connection eliminates the need for such a distorted pin hole which can be cylindrical and only slightly larger, in diameter, than that of the pin.

By this invention, fluid pressure in the hydraulic power line is sensed, to monitor an increase in the fluid pressure as the hydraulic system raises the vehicle coupler while coupled to a railcar. Then, when a substantial termination of the increase in fluid pressure is sensed as the hydraulic coupler is raised, an indicator signals the occurrence of this event, typically by automatically terminating the hydraulic raising of the vehicle coupler. Thus, weight may be transferred without overraising the railcar, without the need for estimating the weight of the railcar prior to the weight transfer process.

  • Patent number: 5279432
    Abstract: A draw bar replacement strap and method for temporarily coupling and moving a disabled railroad car without actuating the drawbar. The strap comprises an elongated, multi-section, multi-ply body extending between a terminal two ply eye through which the strap may be looped and a remote tail. The strap is integrally formed from an elongated, single ply that is appropriately looped and folded. A ratchet system is attached to the strap for tightening. An auxiliary pad is provided for preventing abrasion of the strap when deployed, and for restraining the strap when stored. A multiple ply section forms the eye and extends from the eye to an end journalled to the ratchet. An elongated, double ply body section extends between the ratchet journal and the tail. Through the multi-ply multi-segment structure the tow strength of the cable is vastly improved. In the method the strap is coupled around the towing drawbar, and the tail and ratchet are drawn through the eye.

  • Patent number: 5272986
    Abstract: A vehicle 10 which inspects pipes 12 using flux-leakage has a flux generating electromagnet 14 and foils 18, 20 to transfer the flux to the pipewall 12. Sensors 22 detect flux forced to leak from the pipe by defects. The vehicle is required to pass 1-D bends as shown and has a swivel 40 having a load bar 48 on which there is a link 46 of a towing chain 26. On straight pipe the link 46 occupies a first position nearer to the axis 44. In a bend the swivel turns so that the link 46 can slide along the load bar 48 to a second position further from the axis 44. This reduces the angle which the chain 26 makes with the axis 44 and jamming of the vehicle 10 in the bend is avoided.

  • Patent number: 5193699
    Abstract: The present invention relates to a railway car coupler arrangement whereby a standard yoke, follower, and draft gear are removed from the center sill and replaced with a short yoke member, a spacer block member and slackless drawbar arrangement, namely, a pocket casting wedge shim, and follwer, easily converting the coupler arrangement to a drawbar arrangement without modifying the center sill. The short yoke member, spacer block and slackless arrangement fit exactly within the space formerly occupied by the draft gear pocket casing. The drawbar arrangement maintains the same degrees of angling freedom as the coupler since the drawbar is connected and pivoted from the same pin location as when the coupler was installed. The short yoke member is also designed to more uniformly distribute draft loads to the center sill by transferring forces from the connecting pin into the short yoke member, which in turn transfers those forces into abutting center sill front stops, left intact from the coupler arrangement.
