摘要： A modular add-on unit provides (14) anti-spin protection for a gear-operated locking system (13) of plug-in railway freight car doors (12). The unit has an input shaft (26) with a handle (36) attached thereto, and an output shaft (42) with a recess (40) therein configured for direct engagement with industry standard door shafts. An anti-spin mechanism (24) disposed within a housing (17) couples the two shafts together, and the housing is attached to the outer surface (42) of the door, preferably by welding.

摘要： A replacement roof sheet for replacing a removed roof section of a covered hopper car roof that has cracks radiating from the square corners of a rectangular hatch. The roof sheet has an arcuate cut-out aligned with the hatch opening and an upstanding, arcuate coaming web joined to said roof sheet at said cut-out, the ends of the coaming web forming joints with exposed ends of the roof coaming peripheral of the hatch opening. Two reinforcing members, having dual-angle standards, bridge the joints to reinforce them. Each member has a base portion secured to the roof sheet and the car roof, a first or lower portion conforming to the inward slope of the roof coaming and secured thereto on one side of the joint, and a second or upper portion conforming to the vertical coaming web and secured thereto on the other side of the joint. An end of the roof sheet overhangs an end wall of the car spaced from the hatch and an end sheet depends to said end wall to cover the space therebetween. The end sheet has a lower margin overlapping the exterior surface of the end wall to accommodate variations in dimensions and installations from car to car. Closure blocks seal gaps between the ends of the roof coaming and coaming web; and closure wedges close gaps between the rounded car roof end wall and the planar roof sheet.
摘要翻译：一种替换屋顶板，用于更换具有从矩形舱口的方角辐射的裂缝的覆盖的漏斗车顶的已移除的屋顶部分。屋顶板具有与舱口开口对准的弓形切口，以及在所述切口处连接到所述屋顶板的直立弓形拱形腹板，所述梳理纤维网形成接头的端部具有屋顶连接周边的暴露端舱口开口。两个加强构件，具有双角度标准，桥接接头以加强它们。每个构件具有固定到屋顶板和车顶的基部，与屋顶铰链的向内倾斜一致的第一或下部，并且在接头的一侧固定在其上;以及第二或上部，铰链腹板并在接头的另一侧固定在其上。顶板的一端伸出与舱口间隔开的轿厢的端壁，并且端板与所述端壁相对，以覆盖它们之间的空间。端板具有与端壁的外表面重叠的下边缘，以适应尺寸的变化和从汽车到汽车的安装。封闭块密封屋顶铰链和铰链网的端部之间的间隙; 并且闭合楔住了圆形车顶端壁和平面屋顶板之间的紧密间隙。
