摘要： A rail car having an interior cavity and an end opening for loading and unloading lading. A pair of door assemblies, each of which includes a plurality of panels, each pivotally movable with respect to the other for closing at least a portion of the end opening. Pivot means for mounting each of the door assemblies are provided to move the door assemblies between their respective open position and closed position. The pivot means are mounted for movement toward and away from the interior of the rail car to permit storage of the door assemblies within the rail car when their panels are folded back upon one another. The means for moving the pivot means include a guide means in the form of a pair of parallel racks and co-operating pinions drivingly mounted on a common manually driven shaft, one rack and co-operating pinion each at the top portion and the bottom portion of the door assembly. The rack and pinions function to keep the top and bottom portions in register as the folded door assemblies move along tracks extending normal the opening into the interior of the car for storage. The pinion driving shafts are manually driven and include pawl means which hold the doors in storage until the pawl is automatically removed from the teeth of its associated pinion upon manual pulling out of the door assembly. Intermediate locking means on the edges of horizontally disposed lading deck members adjacent the opening are provided, as well as a final locking means which includes a plurality of cams pivoted for movement in unison on a common locking shaft. The shaft includes a locking flange by which vertically movable interference means can selectively restrain the locking flange to prevent rotational movement of the locking shaft for unlocking of the doors. A pivoted sealing lug and appropriately positioned adjacent apertures on the lug and member prevent movement of the interference member during transit of the car.

摘要： A railway house car is provided with a sliding door and door driver. The door driver includes a lock having a door mounted hasp and upper and lower bracket portions mounted on a fixed door post for common engagement with a locking pin. The lower bracket portion has a pivoted manual lever mounted thereon with a crank arm for providing an increased mechanical advantage. The crank arm extends downwardly to pivotally and drivingly engage a door latch carried on an inner surface of the crank arm. The door latch has an opening on its end opposite the crank arm for selective connection to a flanged boss mounted on a vertical door edge reinforcement member. The lever with its crank arm and the door latch may be made from plate steel.

摘要： A compact door driver is provided on a railway house car for moving a railway car door between a closed or locking position and an open or sliding position. The door driver includes a lever having a crank arm and is rotatably mounted on a structural member of the railway car for movement in excess of 45 degrees. A boss in the form of a roller is mounted on the crank arm. The door driver further includes a door mounted hasp having a cam surface defined end opening in the form of a transverse slot for receiving said boss selectively to drivingly interconnect the lever and the door. When connected to the crank, pivotal movement of the hasp is limited and the hasp, crank arm and boss act similar in manner to a Scotch yoke mechanism. The driver may provide theoretical mechanical advantages substantially within the range of from approximately 8 to 1, to approximately 46 to 1, ignoring friction, depending on the direction of the door and angular position of the crank arm. The railway car door accordingly may be urged between the sliding position and the locking position with a force that is appropriate for the particular position and direction of movement of the door.
摘要翻译： 在铁路车厢上设置一个紧凑的门驱动器，用于在闭合或锁定位置和打开或滑动位置之间移动铁路车门。 门驱动器包括具有曲柄臂的杠杆，并且可旋转地安装在铁路车辆的结构构件上以超过45度的运动。 辊子形式的凸台安装在曲柄臂上。 门驱动器还包括门安装的搭扣，其具有形成为横向槽形式的凸轮表面限定的端部开口，用于接收所述凸起件以选择性地驱动地连接杠杆和门。 当连接到曲柄时，叉头的枢转运动受到限制，并且搭扣，曲柄臂和凸台的作用类似于苏格兰轭架机构。 驱动器可以提供基本上在大约8到1到大约46到1的范围内的理论机械优点，忽略摩擦，这取决于门的方向和曲柄臂的角位置。 相应地，铁路车门可以以适合于门的特定位置和移动方向的力而在滑动位置和锁定位置之间被推动。

摘要： A rail house car with side openings and doors for closing the openings by movement of the doors longitudinally along the car sides and laterally into and out of the openings. Cranks moveably support and retain the doors on longitudinal tracks below the doors and within longitudinal retainers above the doors. The cranks are selectively manually driven for lateral movement of the doors. The top cranks include combination skid and roller devices which permit the doors to move easily because of the rollers when they are longitudinally moved along the track and retainer but which permit the locating of the rollers within recesses in the surfaces of the retainers when the doors are located laterally substantially within their openings along the car sides. The skids provide minimal wear of the surfaces of the retainers when the doors are so located because of the relatively large areas of the skid surfaces in face to face engagement with the retainers' surface portions adjacent the recesses as compared to wear normally created by the rollers' tangential lines of contact with the retainers' surfaces. This wear is usually present in those situations where insufficient structural support for the roof causes vertical vibrations in the longitudinal retainers. The skid and roller combination is also associated with any auxiliary cranks which are in engagement with surfaces of the longitudinal retainers.
摘要翻译： 一种具有侧开口和门的轨道车，用于通过门沿着轿厢侧纵向移动并横向进入和离开开口来关闭开口。 曲柄可移动地支撑和保持在门下方的纵向轨道上的门和门上方的纵向保持器。 选择性地手动驱动曲柄用于门的横向移动。 顶部曲柄包括组合滑动装置和滚子装置，这些装置允许门在沿着轨道和保持器纵向移动时容易地移动，但是当门是门锁时，允许将辊定位在保持器的表面中的凹槽内 大致沿着车侧侧面位于其开口内。 由于与通常由辊产生的磨损相比，由于相对于与凹部相邻的保持器表面部分的表面相对较大的滑动表面的面积相对较大，因此当门位于这样的位置时，滑板提供保持器表面的最小磨损 “与保持器表面接触的切线。 这种磨损通常存在于在屋顶的结构支撑不足导致纵向保持器的垂直振动的情况下。 滑动和滚子组合也与与纵向保持器的表面接合的任何辅助曲柄相关联。

摘要： A door driver is provided on a railway house car for moving a railway car door between a locking position and a sliding position. The door driver includes a lever which is rotatably mounted on a structural member of the railway car. The door driver further includes a plurality of drivingly interconnected drive members, one of which is a driving member and another of which a driven member. The lever is drivingly connected to the driving member. The drive members have a plurality of gear teeth thereon and are rotatably mounted on the railway car with the gear teeth of at least one other drive member. When a force is exerted on the driving member, the driving member transmits that force to the driven member so the force capable of being exerted by the driven member is greater than the force exerted on the driving member. The door driver also includes means for connecting the railway car door to the driven member so that upon movement of the lever, the railway car door is urged between the sliding position and the locking position with a force that is greater than the force exerted on the lever.
