A mounting box has a circular mounting post that accepts circular openings in the shanks permitting them to rotate relative to each other between a closed coupled position and an open uncoupling position. The spring end portions engage the mounting box to bias the shanks into their coupled position. The knuckle carries a ferrous actuating pin that cooperates with a magnetic pad along a track to rotate the upper shank into its open position. Full Article
up Railcar coupler core with vertical parting line and method of manufacture By www.freepatentsonline.com Published On :: Tue, 13 May 2014 08:00:00 EDT A method of casting a core includes the steps of preparing a first half of a corebox, preparing a second half of a corebox such that the parting line of a core formed from the first and second coreboxes runs along the vertical axis of the core.

up Railcar coupler knuckle cores with rear core support By www.freepatentsonline.com Published On :: Tue, 10 Jun 2014 08:00:00 EDT A core assembly for creating interior spaces in a railcar coupler knuckle is designed to be set in a cavity with cope and drag sections. The cavity is shaped to form a railcar coupler knuckle and includes a first wall that forms the substantially vertical outside wall of the tail of the knuckle. The core includes a kidney section with a rear core support section that extends at least 0.5″ outside the first wall of the cavity when the core is set in the drag. Full Article
up Coupling and conduit for consist communication system By www.freepatentsonline.com Published On :: Tue, 10 Jun 2014 08:00:00 EDT A coupling for a communication conduit is disclosed for use with a train consist. The coupling may include a nipple configured for insertion within a fluid conduit, a flange configured to engage an end of the fluid conduit, a retention member configured to engage an outer surface of the fluid conduit, a first fitting extending from the flange away from the nipple, and, a retaining tab configured to retain a second fitting of another coupling in engagement with the first fitting. The coupling may further include a closure mechanism configured to close off an end of the first fitting and movable during engagement with the second fitting to open the end of the first fitting.

up Coupling arrangement for the front of a tracked vehicle By www.freepatentsonline.com Published On :: Tue, 22 Jul 2014 08:00:00 EDT A coupling arrangement for the front of a tracked vehicle is disclosed, comprising a central buffer coupling having a gladhand, a coupling shaft supporting the gladhand and a bearing, via which the coupling shaft can be joined with the undercarriage of the vehicle pivotable in a horizontal and/or vertical direction. An energy consuming device allocated to the central buffer coupling having at least one energy consuming element with a destructive design is provided. To ensure maximum energy consumption in a crash with a course of events definable in advance, the coupling arrangement additionally comprises a supporting structure with two longitudinal beams arranged on the sides of the central buffer coupling and a crossbeam joined with the two longitudinal beams, said crossbeam beam being arranged above the central buffer coupling such that a vertical deflection of the coupling shaft relative to the undercarriage of the vehicle is limited by the crossbeam.

up Use of no-bake mold process to manufacture railroad couplers By www.freepatentsonline.com Published On :: Tue, 22 Jul 2014 08:00:00 EDT A railroad coupler assembly having at least a body and a knuckle both formed in a no-bake manufacturing process, the body and the knuckle having dimensional tolerances of distances between features that wear during operation that are about half those obtained from a body and a knuckle manufactured by a green sand process, resulting in increased fatigue life compared to the body and the knuckle manufactured by a green sand process. The body and the knuckle resulting from the no-bake manufacturing process have no observable laps, scabs, chaplets or welding in critical areas of the body and knuckle, which are reflected in surface conditions matching SCRATA (Steel Castings Research and Trade Association) values of: D1 (laps); E1 (scabs); F1 (chaplets); and J1 (welds).
