摘要： A modular center filler for railway vehicles comprising an inverted U-shaped core member fitted between front and rear cover plates and securely attached to a bottom cover plate to which a center plate is attached. Downwardly extending legs of the core are aligned with corresponding inner, beveled edges of the center plate which receive high forces during transit as a car rocks back and forth. The core member is positioned to receive these forces and transmit them into the center filler structure, car bolster and car body framing for even distribution throughout the vehicle.

摘要： A door operating mechanism for a bottom dump railway hopper car including a plurality of longitudinally mounted, divergently opening discharge doors held in the closed position by a plurality of longitudinally spaced claw-like latches. Each pair of transversely opposite latches includes operating rods connecting each latch to a bell-crank positioned beneath the longitudinal hood of the car. The bell-cranks are operatively connected to a longitudinally disposed tension rod, which includes linkages at either end for actuation of the mechanism by trackside mounted cams.

摘要： Method of converting a hopper type of rail car to accept a wider outlet gate permits existing cars which are in over-supply to be made useful. The method requires that the opposed pairs of side slope sheets of the original car, and the opposed pairs of center and end slope sheets which are joined to them to form the bottom portions of the hoppers, be cut apart. One of the pairs of slope sheets then has its width reduced at its lower end portion while the lower end portions of the other pair of slope sheets are cut away and replaced by new slope sheet portions which are of greater width than the original portions. After the mounting flanges for the original outlet gates are removed, new mounting flanges which are wider in one direction and narrower in the other, are located in a predetermined fixed position relative to the frame of the car, preferably by an assembly jig which is temporarily clamped to the car frame. The pair of slope sheets which had its width reduced is then bent outwardly into contact with the mounting flange. The new pair of slope sheet portions is then welded into position relative to the hoppers and the pair of slope sheets whose width was reduced. To relieve stress in the slope sheets which are bent outwardly, the seam about which they are bent relative to the hoppers is heated.

摘要翻译： 将料斗式轨道车转换为接受更宽的出口门的方法允许现有的供应过剩的汽车变得有用。 该方法要求将原始轿厢的相对的侧边坡形片和连接到它们的相对的中心和端部斜面片对形成料斗的底部部分切割。 一对斜面片中的一对在其下端部分的宽度减小，而另一对倾斜片材的下端部分被切掉并被新的斜面片部分所替代，该斜面片部分的宽度大于原始部分。 在拆卸原始出口门的安装法兰后，在一个方向上较宽且另一个方向较窄的新安装法兰相对于轿厢的框架位于预定的固定位置，优选地通过临时的组装夹具 夹在车架上。 然后将其宽度减小的一对斜面片向外弯曲成与安装法兰接触。 然后将新的一对倾斜片部分相对于料斗和宽度减小的一对倾斜片焊接到位。 为了缓解向外弯曲的倾斜片中的应力，加热了相对于料斗弯曲的接缝。

摘要： A door lock mechanism for hopper cars includes a longitudinally extending operating rod actuated by a linkage means tripped by a track side cam. The rod in turn actuates cam locks by means of bell cranks which cause the locks to rotate and release transverse tension rods connected to doors for opening the same. The cam locks include cams engageable with teeth on the tension rods for securely locking the doors in a closed position. The operating rod also includes cam means effectively engaging the cam locks to positively lock the same in a closed position.

摘要： The invention is of a hatch assembly that includes a hatch cover adapted to seal a hatch opening defined by a raised combing of a deck. A locking arm having a hinge end and a lacth end extends across and beyond the hatch, and has a hatch clip adjacent each end to floatingly connect the locking arm to the hatch cover. A latch is mounted to pivot arms to engage latch engagement structure on the locking arm with a force dependent on the height of the pivot arms from the deck. An adjustment member includes tool bearing surfaces to enhance the rotation of the adjustment member and thereby adjust the force. A latch handle includes a stiffening member to strengthen the handle against forces tending to rotate the latch handle about the pivot arms. A pair of hinge bracket walls are mounted to the hatch combing and define a hinge bracket space between them. A stop is affixed to the bracket walls to prevent the hatch cover from contacting the horizontal deck surface. The hatch clip at the hinge end of the locking bar includes a flat clip base joined to two clip side walls by repective clip arcuate portions. The clip side walls fit outwardly of a hinge member within the bracket space. Shim are located between the clip side walls and the hinge member to bias the hinge member inwardly of the clip side walls and into abutment with the flat clip base.

摘要： The hatch of a cargo vessel, such as the hopper of a covered hopper car, is sealed by a hatch cover having a locking arrangement which prevents the hatch cover from being blown open by pressure within the hopper upon unlocking the lock. An over center locking arm has two locking detents on it which coact with two locking detents on a locking bar to selectively provide a sealed, pressure blow off and hatch open position. A rotative adjustment is provided to enable the sealing pressure of the hatch cover on the hatch to be selectively adjustable.
