Definitions

  • This invention relates to resilient centering mechanism for supporting a railway car coupler at a point forwardly of its point of primary connection with the car.
  • the invention is concerned particularly with a centering arrangement which may be conveniently inactivated to permit the coupling of cars in relatively angled relationship as when positioned on a curve of the railway.
  • couplers and car components for connecting them to cars which provide a side-toside angling range of a coupler relative to its car not exceeding about 16 inches whether or not mechanism is provided for resiliently centering the coupler.
  • Such structure is usually arranged to permit a vertical angling range centered on the horizontal of approximately 6 inches. Horizontal and vertical angling ranges greater than these are not desired because of greater size and weight Olf the car components which receive and support the coupler within the end of the vehicle, and encroachment upon the space, e.-g., the Berne rectangle, needed by the train crew for train operation.
  • the need to position an automatic coupler in angled relationship with its parent vehicle prior to coupling with another vehicle is particularly desirable in the operation of side bufier vehicles in order that trainm'en may be clear of the between-car region during coupling.
  • the need for positioning the coupler at an angle relative to its parent car prior to coupling is particularly evident when coupling a car located on a curve with another car located on a tangent to the curve.
  • the coupler heads of the two cars in this instance are displaced from the center of the track at different distances.
  • the coupler heads are laterally displaced in opposite directions from the center of the track.
  • coupler centering mechanism which may be temporarily inactivated and the coupler shifted to horizontally offset angled positions.
  • Another object is to provide a coupler centering mechanism resiliently acting upon a coupler to center it both vertically and horizontally with respect to the neutral position of its longitudinal axis.
  • a further object is to provide centering mechanism in accordance with the foregoing objects which may be readily placed in condition for shifting the coupler to an angled position from either side of its neutral position.
  • Still another object is to provide a coupler centering mechanism having the deactivating or releasing feature referred to immediately above which is substantially housed within a striking housing or casting.
  • a device for supporting a car coupler within the underfrarne of a railway vehicle which, in its broadest aspect, operates to center and resiliently support a coupler along a predetermined path of movement for at least a portion of the device.
  • Such path extends in a usually horizontal direct-ion in transverse relation to the length of the coupler.
  • the device includes a coupler-supporting portion in resilient, laterally traversable relation with another portion; but
  • the device comprises a carrier for the coupler shank having an upper portion providing opposed surfaces spaced in a direction extending transversely of the length of the coupler for receiving the shank; a cage situated next to the carrier in the lengthwise direction of the coupler and connected with the carrier in guide relationship for movement of the carrier relative to the cage in the transverse direction; and resilient means disposed operatively between the carrier and the cage and acting therebetween to urge the carrier in the transverse direction to a neutral position relative to the cage.
  • the device further comprises a support connected with the underfra'me for supporting the cage in a manner permitting its movement along a course aligned in the transverse direction of the device and the vehicle; and a detent system having a portion on the support and another portion on the cage engageably cooperating to prevent transverse movement of the cage relative to the support from a centered position during normal operation of the device.
  • the detent system is constructed for urging the portions thereof into interlocking relationship as soon as the coupler shank is returned to a non-angled centered relation with the device.
  • FIG. 1 is a perspective view of an assembly including a striker casting and mechanism supported therewithin providing a resilient support of a coupler with respect to a neutral alignment or position relative to its primary point of connection with the vehicle.
  • FIG. 2 is a perspective view of a sub-assembly from the assembly of FIG. 1, illustrating a coupler carrier movably mounted, and partially contained, within a casing or carrier support.
  • FIG. 3 is a lateral elevation of a coupler carrier shown also in FIGS. 1 and .2.
  • FIG. 4 is a front elevation of the carrier in FIGS. 1, 2, and 3.
  • the term front as used herein and below, has reference to a longitudinal direction of a railway vehicle extending away from its center. That is to say, a front view is that observed when looking from a point along said axis toward the center of the vehicle.
  • FIG. 5 is a lateral elevation of a cage included in FIGS. 1 and 2 for receiving the carrier of FIGS. 3 and 4.
  • FIG. 6 is a front elevation of the cage shown in FIG. 5.
