  • Patent number: 11400911
    Abstract: Methods, systems and a kit for indicating brake air pressure status in brake pipes of multiple interconnected train cars are provided. The methods include operating at least one end-hose adapter per train car. Each end-hose adapter is mounted between a train car end hose and a brake pipe to be in fluid communication therewith and are configured to sense the brake air pressure in the brake pipe. Each end-hose adapter kit includes connections adapters for connecting either end to different parts of the train car system. The end-hose adapter provides a first visual indication when the brake air pressure is within an operable range and/or a second visual indication when the brake air pressure is below an operable value and is experiencing leakage.
    Type: Grant

  • Patent number: 7267306
    Abstract: A hybrid support bracket for supporting a flexible end hose of a railcar air brake hose assembly is described. The bracket has a free end of a predetermined length and a train line support unit is displaceable along the displaceable free end. The train line support union has a connector which connects an end of the flexible end hose to the brake hose assembly. The hybrid bracket is secured to the yoke of a coupler and is displaceable therewith. The displaceable free end and train line support union permit relative displacement between the hybrid bracket and the hose support to compensate for the slack of the coupler due to wear.
