  • Patent number: 5480218
    Abstract: A pipe bracket for use in a freight brake control valve on a railway freight vehicle. A service portion and an emergency portion are mounted to a first pipe bracket side directed opposite to the first pipe bracket side. Piping to a brake pipe, a brake cylinder, an emergency reservoir and an auxiliary reservoir are connected to a second side of the pipe bracket. A plurality of passageways are provided through the pipe bracket portion for providing fluid communication from the brake pipe, the brake cylinder, the emergency reservoir, and the auxiliary reservoir to the service portion and the emergency portion. One or more and preferably four access ports connect to one or more and preferably each of the passageways. Preferably, the access ports are provided on the first side of the pipe bracket portion. A housing having one or more channels, each corresponding to an access port is engaged to the pipe bracket portion so that fluid pressure at the access ports can be transmitted to the housing.

  • Patent number: 4867279
    Abstract: A low-profile railway car retarder having a pair of braking bars disposed parallel and on opposite sides of a track rail and having an upper and lower pivotal lever carrying a respective one of the pairs of braking bars. A pneumatic motor pivotally connected to the outer extremities of the upper and lower levers, and the height of the pivotal connection of the upper lever is substantially at the same level as the track rail so that a humped railway vehicle is permitted to freely pass through the car retarder. The pneumatic motor lifts the upper lever and depresses the lower lever to move the pair of braking bars to a closed braking position wherein pressure is supplied to the pneumatic motor so that the pair of braking bars engage the opposite side of the wheels of a traversing vehicle at a relatively high point to exert a greater amount of retardation of the vehicle.
