摘要： A locking device for a pair of mating air brake hose coupling members includes a housing with a first aperture for attachment to one 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 reciprocally disposed 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.

摘要： A friction-type draft gear assembly includes a housing having an open front end and a closed rear end forming a ledge to fit into a 24.625 inch draft gear pocket. The front portion incorporates an integral yoke portion with a pair of key slots for attachment to the coupler. A coupler follower is disposed within open front end and communicates with a pair of apertures during buff and draft travel. A compressible cushioning means is positioned within the second end with a seating arrangement abutting an end wall thereof and is extended longitudinally toward the open front end. A friction cushioning element is provided in the open front end of the housing. A spring release mechanism is adapted for continuously urging the friction cushioning element outwardly from the compressible cushioning means thereby releasing such friction cushioning element after compression of such draft gear assembly.

摘要： A friction-type draft gear assembly includes a housing having an open front end and a partially closed rear end with a first and second rear portions and a pair of ledge members disposed intermediate such first and second rear portions for enabling the draft gear assembly to fit into a draft gear pocket of a predetermined length. A first rear portion is adapted to receive a compressible cushioning element with a seating arrangement abutting one end thereof which extends longitudinally from the second portion of the closed rear end toward the open front portion. A removable bottom wall is attachable either to the first or second rear portions for enabling installation of the compressible cushioning element through the first end. The open front end is adapted to receive a friction cushioning means which has a spring release mechanism for continuously urging the friction cushioning means outwardly from the compressible cushioning element thereby releasing such friction cushioning means after compression of such draft gear assembly. The open front end is configured for direct attachment to a coupler with a coupler key.

摘要： The present invention provides an improved TMX.RTM truck mounted brake assembly for applying a brake shoe force to a railway car wheels by interfacing with an axle motion III bogie. The improvement comprises a rack and pinion type hand brake mechanism integrally mounted on at least one truck bogie per railway car. The hand brake mechanism utilizes a plurality of gear/pinion arrangements to transmit the force applied at the drive wheel to the transfer lever disposed within the TMX.RTM truck mounted brake assembly to effect the brake application. The hand brake mechanism is disposed within the spatial confines of the TMX.RTM truck mounted brake assembly and axle motion III bogie. The brake beams of the brake assembly are of the open box construction to accommodate such hand brake mechanism. A visual indicator is provided to identify the hand brake in both fully applied and fully released positions.

摘要： 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.

摘要： A hand brake having mechanism for retaining the hand brake in a substantially released and hold position to prevent unwanted application of the railway car brakes due to vibration or other energy sources during railway car motion. Such mechanism includes at least one spring mounted to the hand brake housing substantially engaging a release lever disposed within a quick release mechanism so as to prevent reverse rotation of the release lever causing an unintended take-up of the chain.
