摘要： A railway car coupler system includes a railcar coupler comprising 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 coupler pivot pin hole for receiving a pivot pin for coupling the railcar coupler to the first coupler knuckle. The pivot pin hole has a longitudinal axis. The coupler head portion comprises top and bottom coupler pulling lugs each having a respective coupler pulling lug engagement face. At least one of the coupler pulling lug engagement faces of the top and bottom coupler pulling lugs is angled with respect to the longitudinal axis.

摘要： A linkage-actuator for the coupler knuckle-assembly of a railway passenger car which is mounted on the coupler head directly adjacent to the knuckle-assembly, which linkage-actuator does not extend along the shank connecting the knuckle-assembly to the car proper, thereby saving considerably on space and weight. The linkage-actuator allows for both manual and pneumatic actuation of the knuckle-assembly. The linkage-actuator for the knuckle-assembly is mounted directly on the coupler head. The rotatable operating rod for placing the knuckle into its lock-set or fully open position is actuated by a pivotal plate mounted on top of the coupler head. One end of the plate is urged into its non-actuated, horizontal position by a spring, while the other end of the plate is connected to an eccentric cam that is coupled to the rotatable actuating rod of the knuckle-assembly. An air-bellows lifts the end of the plate coupled to the eccentric cam which, in turn, rotates the actuating rod, to thereby place the knuckle into its lock-set or fully thrown position.
摘要翻译： 一种用于铁路客车的联轴器转向节组合的联动致动器，其安装在与转向节组件直接相邻的联接头上，该联动致动器不沿着将转向节组件连接到汽车本体的杆延伸， 从而大大节省了空间和重量。 联动执行器允许手指和气动致动转向节组件。 用于转向节组件的联动执行器直接安装在联轴器头上。 用于将转向节放置在其锁定或完全打开位置的可旋转操作杆由安装在联接器头部顶部上的枢转板致动。 板的一端通过弹簧被推动到其非致动的水平位置，而板的另一端连接到联接到转向节组件的可旋转致动杆的偏心凸轮。 空气波纹管提升联接到偏心凸轮的板的端部，该偏心凸轮又使转动杆旋转，从而将转向节置于其锁定或完全抛出位置。

摘要： A pair of elongated latches positioned transversely to a longitudinal axis of a railroad car particularly adapted to be rotated to an upside down position for gravity release of contents within the car, are pivotally attached respectively on each side of a top of a coupler lock. The coupler lock is an operative part of a coupler for the railroad car. The lock is movable within a lock chamber formed in a head of the coupler and is defined in part by vertical sidewalls and a roof or top wall. A configuration of each latch and relative position to the lock chamber sidewalls is such that a center of gravity of each latch lies above its pivot connection which insures that regardless of the direction of rotation of the car, at least one of the latches readily swings to an extended position to engage the top wall of the lock chamber and thereby prevent an inadvertent release of the lock when the car and at least one pair of mated couplers are rotated toward an inverted position for emptying contents of the car.

摘要： This invention relates to a railway car coupler of the knuckle type and provides an improvement in the operation of a standard E coupler during a coupling operation. In particular, it concerns the provision of a lock lifter toggle which will assure dropping of the lock to its final locking relation with the coupler knuckle when the knuckle is closed during a coupling operation.
