  • Patent number: 9540021
    Abstract: A contaminant mitigation device for use with a slack adjuster for a railway brake rigging to protect the critical operating area of the slack adjuster. The critical operating area of a slack adjuster includes the components that are configured to operate together to adjust the brake rigging. The slack adjuster includes at least a main housing portion, a cone nut housing portion enclosing the critical operating area of the slack adjuster, and an overtravel housing portion. The contaminant mitigation device includes a sealing system configured for cooperating with at least one of the main housing portion, cone nut housing portion, and overtravel housing portion to seal the critical operating area against entrance of fluid and/or contaminants therein and/or to at least reduce the exposure of this area to fluid and/or contaminants. The contaminant mitigation device can also include a drainage system associated therewith.

  • Patent number: 8469464
    Abstract: A parking brake assembly for a railway car includes a ratchet mounted for rotation on a threaded piston rod of a brake actuator and a holding pawl engageable with the ratchet for maintaining a push rod of the parking brake assembly to apply braking force when the air pressure is lost in the brake pipe and releasing the push rod to accordingly release the braking force when the supply of air pressure in the brake pipe is restored. An operating lever and a cylinder connected thereto are provided for selectively rotating the holding pawl. Valve is provided for supplying air pressure to and evacuating it from the cylinder. Release mechanism is provided for manually releasing the braking force. The parking brake assembly is employed with either truck-mounted or carbody-mounted braking system.

  • Patent number: 8381886
    Abstract: A release holding mechanism for a railcar hand brake includes a release shaft rotatably mounted in the housing. A quick release handle is rigidly secured to an external end of the release shaft for rotation therewith and manually rotatable into a release position to initiate the quick release of the railcar brake application. A release lever cooperates with a driving mechanism of the hand brake to effect quick release of the railcar brake application. A release ratchet wheel is mounted for rotation with the driving mechanism. A release pawl operably engages the release ratchet wheel when the driving mechanism rotated for releasing the brake application. A gravity weighted member is disposed on and rigidly secured to the release lever for maintaining the release pawl, due to gravity, in a disengaged position relative to the release ratchet wheel when the driving mechanism is manually operable for effecting the brake application.

  • Patent number: 8256584
    Abstract: A parking brake assembly for a railway car includes a ratchet mounted for rotation on a threaded piston rod of a brake actuator and a holding pawl engageable with the ratchet for maintaining a push rod of the parking brake assembly to apply braking force when the air pressure is lost in the brake pipe and releasing the push rod to accordingly release the braking force when the supply of air pressure in the brake pipe is restored. An operating lever and a cylinder connected thereto are provided for selectively rotating the holding pawl. Valve is provided for supplying air pressure to and evacuating it from the cylinder. Release mechanism is provided for manually releasing the braking force. The parking brake assembly is employed with either truck-mounted or carbody-mounted braking system.

  • Patent number: 7802689
    Abstract: An articulated coupling apparatus utilized in connecting together, in a substantially semi-permanent fashion, adjacently disposed ends of a pair of railway cars includes male and female connection members. A front and rear followers, each having a spherical cavity, are positioned within the female connection member. First and second lubricating liners are positioned within such spherical cavities and a spherical member is operably caged between such lubricating liners. A shaft is attached to the spherical member and extends outwardly from the female connection member for secure connection to the male connection member. A pair of wedges are mounted adjacent the rear surface of the rear follower and exert a force onto such rear follower moving it toward the spherical member and further toward the front follower to compensate for wear of the mating spherical surfaces during service and to prevent formation of a gap between the mating surfaces.
