  • Patent number: 7461867
    Abstract: An apparatus for lifting a brake hose including a glad hand secured to one end thereof. The brake hose to be lifted into an elevated position is attached to an end of a railway car. Such apparatus further maintains the brake hose in such elevated position during in track service. Such apparatus includes a first member engageable with a predetermined portion of such railway car and a second member engageable with one of such glad hand and such brake hose. There is at least one fluid pressure actuated expansion member disposed between and engageable with such first and second member. Additionally, a supply line having a choke is disposed in fluid communication with such at least one fluid pressure actuated expansion member and a source of fluid pressure for expanding the expansion member in a longitudinal direction and thereby raise such brake hoses to a predetermined elevated position.

  • Patent number: 7461869
    Abstract: “An air brake hose coupling member includes a locking device having a housing with a first aperture for attachment to the air brake hose coupling member and a second aperture for attachment to a hose support member which is adjusted to provide a predetermined clearance between the air brake hose coupling and a rail track. A locking pin is mounted for reciprocal movement within the housing and is being urged. by a resilient member in one direction for preventing undesirable complete rotational uncoupling of such pair of mating air brake hose coupling members. The locking pin is manually movable in the opposite direction during coupling and uncoupling under normal operating conditions. Alternatively, the housing is provided as a boss formed on a body of the air brake hose coupling.

  • Publication number: 20080264890
    Abstract: The present invention increases the capacity and resistance to closure of the draft gear assembly by providing an angled surface on the tapered plates intermediate of the inner and outer friction surface in the area where the tapered plate contacts the third horizontal rib of the housing. Providing an angle on the edge surface of the tapered plates in this area increases the side force on the movable plates during the application of a buffing shock to the draft gear assembly.

  • Patent number: 7258243
    Abstract: A draft gear assembly includes a yoke and a coupler follower disposed within the yoke. A front compressible resilient member is disposed intermediate the yoke and the coupler follower. A rear compressible resilient member engages a back wall of the yoke at one end and engages a rear follower at a distal end. A center rod extends through the rear compressible resilient member and the rear follower and engages a shortening member. A plurality of stops members are attached to the back wall of the yoke for limiting compression of the rear compressible resilient member during buff travel. The stop members may be extended toward the coupler follower for limiting compression of the front compressible resilient member during draft travel. Alternatively, a center rod or elastomeric pads may be adapted for limiting compression of the resilient compressible members during buff and draft travel. Stops for limiting compression may be also attached to a center sill.

  • Patent number: 7216940
    Abstract: An apparatus engageable with a railway vehicle truck-mounted braking system for compensating for truck bolster movement which includes at least one force transmitting wedge member movable in a reciprocating motion by a pneumatic actuator. The at least one force transmitting wedge member engage rollers rotateably attached to a return push rod member disposed within the truck-mounted braking system for extending the return push rod member to reduce brake shoe clearance prior to brake shoe application. A method for compensating for truck bolster movement also includes fully pressurizing a wedge actuator prior to pressurizing the main brake apparatus actuator. Depressurization of the system returns the force transmitting wedges and return push rod to their original positions upon completion of brake application, subsequently increasing brake shoe clearance for allowable truck bolster movement.
