Uncoupling Devices Patents (Class 213/159)
  • Patent number: 8356721
    Abstract: A spring retention device particularly well suited to use on railcars. The spring retention device has first and second fingers that oppose each other at inclined interior surfaces to define an opening. The interior surfaces overlap and are inclined relative to opposed substantially parallel and planar surfaces with which the first finger is substantially aligned between aside from its terminal end which is bent so the first finger extends outwardly from the first planar surface. The opening terminates in an enlarged portion that has an interior surface defining the perimeter of the enlarged portion. The interior surface of the enlarged portion is substantially perpendicular to the planar surfaces. Springs having eyes that have their wire bent in substantially the same plane may be inserted through the opening, then when turned to align with the enlarged portion, the spring contained therein will be prevented from backing out of the opening.

  • Patent number: 7900786
    Abstract: A telescoping, uncoupling lever for a railroad car. The lever is formed of round rod and includes a handle rod, a lock lifter rod and a track assembly. The track assembly includes a handle rod track and a lock lifter rod track with tracks connected to each other at their opposite ends. A glide housing is attached to one end of the handle and lock lifter rods to allow the handle and lock lifter rods to slide on the tracks of the track assembly. Each glide housing is tubular, has a cavity extending there through to connect rod openings at the opposite ends and has glide of C-shaped transverse cross-section positioned therein to receive and partially encircle a rod.

  • Patent number: 7686177
    Abstract: An improved lever assembly for uncoupling railroad cars having a coupler that includes a lock lifter. The lever assembly has a handle on one end that is pivotally connected to the railcar and a hook located at the other end of the lever assembly that is connected to the lock lifter. The assembly has levers that slide relative to each other. The levers are held adjacent to each other by enclosures through which the levers slide. The enclosures contain U-shaped glides held stationary relative to the enclosures. Typically made of plastic, the glides provide low friction sliding contact with levers sliding through them. The glides are longitudinally shorter than their containing enclosures providing protection from ultraviolet light.

  • Patent number: 7562781
    Abstract: A cut lever apparatus that automatically actuates a lock lift assembly to either lock or unlock a coupler knuckle of a freight car coupler. The apparatus includes a cylinder member having a piston disposed therein. A bracket member is attachable to the freight car coupler to support the cylinder. A linkage member is connected to the piston of the cylinder and the lock lift assembly to convert a lateral motion of the piston to a curvilinear motion of the lock lift assembly to either lock or unlock the coupler knuckle. A valve member is connected to the cylinder for communicating a pressurized fluid to the cylinder when a predetermined signal is sent to the valve and preventing pressurized fluid from entering the cylinder in an absence of the predetermined signal. Pressurized fluid in the cylinder is vented to atmosphere when the valve shuts off supply of pressurized fluid thereto.

  • Patent number: 6739464
    Abstract: An elongated tubular glide housing for a telescoping, uncoupling lever for a railroad car. A tubular glide housing includes a rectangular seal enclosure having a top wall, a bottom wall, an outwardly located side wall, and an inwardly located side wall defining a passage extending through the enclosure. The top and bottom walls of the enclosure have leading and trailing edges. A circular tool opening is formed in each of the outwardly and inwardly located side walls. A pair of elongated plastic glide elements are positioned in the passage extending through the rectangular steel enclosure. Each of the elongated plastic glide elements is formed with a generally L-shaped transverse cross-section including a first leg and a second leg. The L-shaped elements are dimensioned to fit into the passage of the steel enclosure. Each of the first and second legs have a leading edge and a trailing edge. An outwardly projecting retaining tab is formed at each of the leading and trailing edges of the first leg.

  • Patent number: 6206215
    Abstract: Disclosed herein is improvement of the standard Type-E or Type-F coupler, which is compatible with the existing standard couplers, for providing automatic uncoupling features. The improved coupler includes a coupler head of the type having standard coupling knuckle, guard arm, and an standard interior knuckle-control structure within a lock-receiving chamber. Said interior knuckle-control structure includes the standard components such as a knuckle-lock attached to a lock-lift assembly, a knuckle thrower and other standard components. In order to provide the coupler with automatic uncoupling feature, an electric actuator, such as a motor or a solenoid, is installed within a chamber provided behind said guard arm. Said actuator controls the movement of the lock-lift assembly via a leverage system provided so that the coupler lock can be lifted to the lock-set position by said actuator. The actuator is connected to and controlled by the serialization and operation-control system of the train.

  • Patent number: 4460099
    Abstract: Two side-by-side housings each receive a telescoping member therein. Bearings captivated within each housing engage the telescoping members such that the bearings are free to slide both with respect to the housings and the telescoping members. A handle for operating the lever and an arm for engaging the car coupler are mounted to opposing distal ends of the telescoping members. The other ends of the telescoping members are free to extend beyond the housings and have stops which abut the bearings while these ends are disposed within the housings.
