| 20120097631 | Rotary Coupler for a Railway Car - A railcar coupler system that includes a yoke comprising a front end, a rear end, a top strap, and a bottom strap. The top strap and the bottom strap are positioned between the front end and the rear end. The front end comprises an internal bearing surface that is obliquely angled with respect to a central axis of the yoke that extends from the front end to the rear end of the yoke. The system also includes a connector configured to rotate within the yoke such that an axis of rotation of the connector is substantially aligned with the central axis of the yoke when the connector is positioned within the yoke. The connector includes an external bearing surface that is obliquely angled with respect to the axis of rotation of the connector and configured to correspond to the internal bearing surface of the yoke. | 04-26-2012 |
| 20110266242 | Coupler Knuckle System and Method - A method for manufacturing a railcar coupler knuckle includes providing a first mold section having internal walls defining at least in part perimeter boundaries of a first coupler knuckle mold cavity. The method includes providing a second mold section having internal walls defining at least in part perimeter boundaries of a second coupler knuckle mold cavity. The second coupler mold cavity of the second mold section is offset from the first coupler mold cavity of the first mold section. The method includes closing the first and second mold sections and at least partially filling the first and second coupler knuckle mold cavities with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle. | 11-03-2011 |
| 20110197461 | Railway Car Coupler Head Contour Gauge and Method - A railway car coupler head contour gauge includes a cylindrical portion configured to be rotatably coupled to a coupler head. The railway car coupler head contour gauge also includes a pulling lug gauging portion, and a contoured gauging surface that is configured to align with a contour face of a top pulling lug of the coupler head during gauging. The coupler head contour gauge may also include a convex portion configured to align with a buffing shoulder of the coupler head. | 08-18-2011 |
| 20110163059 | Railcar Coupler System and Method - A railcar coupler includes a coupler head portion extending from a shank portion. The coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler head portion comprises a nose portion and a gathering face extending from the nose portion for engaging a second coupler knuckle coupled to the second railcar coupler. The coupler head portion comprises a guard arm portion extending from the nose portion towards the shank portion. The coupler head portion comprises a horn portion having a back surface. A distance between the back surface of the horn portion and a nose end of the guard arm portion is less than 11 inches. The coupler head portion comprises a locklifter shelf less than 2 inches above a bottom edge of the coupler. | 07-07-2011 |
| 20100326943 | Railcar Coupler System and Method - A railcar coupler includes a coupler head portion extending from a shank portion. The coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler head portion comprises a nose portion and a gathering face extending from the nose portion for engaging a second coupler knuckle coupled to the second railcar coupler. The coupler head portion comprises a guard arm portion extending from the nose portion towards the shank portion. The guard arm portion comprises a minimum height less than a height of the shank portion where the guard arm portion meets the shank portion. | 12-30-2010 |
