摘要： A railway hopper car is provided with bottom discharge doors which include an opening and closing mechanism for each of the doors. The mechanism comprises a bell crank lever and linkage arrangement which in the closed position assumes an over-center lock position. The doors are initially actuated to an open position for affecting gravity discharge by means of a track side cam. A second closing cam structure is provided, which, as the car passes therethrough on opposite sides of the track, the bell crank lever and linkage mechanism is again moved to its closed over-center position locking the doors. The closing cam includes a spring actuated portion built into the cam face which is adapted to assist in the operation of the bell crank lever again moving to its over-center position.

摘要： A railway hopper car having bottom dump discharge openings include a bell crank arm which is pivoted by a camming arrangement positioned adjacent to track to an opened position whereby a load is discharged. An auxiliary latch is provided which in the normal operating condition of the train locks the arm against rotation to prevent opening of the doors. The camming device includes an arrangement which is first engaged by an auxiliary latching element which is moved to a release position whereby a cam follower engages the camming face of a cam to thereby pivot the bell crank to its open position.

摘要： A hopper discharge structure is provided with slope sheets defining a throat over a pneumatic outlet tube. The throat is closed by two sliding valve plates. The valve plates are moved by crank arrangements which provide an operator with varying mechanical advantage in operating the valve means. The crank arrangements are mounted on operating shafts extending the length of the hopper. The operating shafts extend through the hopper end walls and are adjustably supported for rotation by reinforcement plates adjustably mounted on the end walls. The operating shafts are equipped with handles which accommodate the insertion of an extension bar from two different directions. The outlet tube is covered by a hinged cap and locking structure. The cap is cammingly sealed over the end of the outlet tube by a cam lock and handle mounted on the locking structure. Outward force on the handle unlocks and withdraws the cap from the end of the outlet tube. The cap locking structure includes a catch which latches it away from the outlet tube in the open position.

摘要： A plastic hatch cover is secured over a hatch opening by a hold-down bar extending across the hatch opening above the hatch cover. The hold-down bar has one end pivotally connected with a hinge bracket on the upper deck and another end engageable with a latch structure for sealing the hatch cover. The hatch cover is secured to the hold-down bar by clips on the hold-down bar adjacent the latch structure and adjacent the hinge. The clip adjacent the hinge detaches from the rest of the hold down bar when the hinge bolt is withdrawn, allowing removal of the hatch cover. Lug portions extend upwardly from the hatch cover to engage the hold-down bar to prevent lateral motion of the hatch cover with respect to the hold-down bar. The hatch cover is provided with reinforcing webs on its upper surface and on its lower surface.

摘要： A railway hopper car has a hatch opening defined by its upper deck surface. A hatch cover is adapted to close the hatch opening. A hinge arrangement is connected with the upper deck surface and a locking arm extends from the hinge arrangement and across the hatch cover, being connected to the hatch cover. The hinge arrangement has a stop thereon which supports the hatch cover when it is pivoted open. The locking arm has a hatch engagement portion on the end opposite the hinge arrangement which is engaged by a latch structure connected with the upper deck surface. The latch structure includes a pivoting latch holder and latch which may be engaged with the latch engagement portion and rotated in one direction to seal the hatch cover and rotated in the opposite direction to unseal the cover. When the latch is rotated to unseal the cover, any excess pressure in the car causing the hatch cover to rise will rotate the latch holder into an extended position where the hatch cover is retained loosely over the hatch opening, and the pressure is allowed to escape. The link has a pivotal connection with the coaming bracket to provide for complete disengagement of the cover from the hatch. The pivotal connection is eccentrically mounted in a cylindrical adjustment member secured by a set screw. Selective rotation of the cylindrical member adjusts the tightness of the hatch cover seal over the hatch opening.

摘要翻译： 铁路货车有一个由其上甲板表面限定的舱口。 舱口盖适合关闭舱口。 铰链装置与上甲板表面连接，并且锁定臂从铰链装置延伸并穿过舱口盖，连接到舱口盖。 铰链装置在其上具有止动件，当其枢转打开时支撑舱口盖。 锁定臂在与铰链装置相对的端部上具有舱口接合部分，该舱口接合部分由与上甲板表面连接的闩锁结构接合。 闩锁结构包括枢转闩锁保持器和闩锁，其可以与闩锁接合部分接合并沿一个方向旋转以密封舱口盖并沿相反方向旋转以开封盖。 当闩锁旋转以开启盖子时，导致舱口盖升高的汽车中的任何过大的压力将使闩锁保持器旋转到延伸位置，在该位置处，舱口盖松动地保持在舱口开口上方，并且允许压力逃逸 。 该连杆具有与支架支架的枢转连接，以提供盖子与舱口完全脱离接合。 枢转连接偏心地安装在由固定螺钉固定的圆柱形调节件中。 圆柱形构件的选择性旋转调节了舱口盖上的舱口盖密封件的密封性。

摘要： A railway car underframe comprises a center sill having bell mouth draft housings at opposite ends thereof. The housings accommodate the use of drawbars or shank type couplers. With the use of a shank type coupler a draft housing extension is secured to the bell mouth housings. The housings include structural shear elements interengageable with each other to align and secure the housings in rigid relation. The housings include connector plates secured together by fasteners with said connector plates longitudinally spaced apart to provide vertical spaces. Wedge elements having open end vertically spaced recesses are driven into the vertical spaces to provide for rigid metal to metal contact with the spaces accommodating the fasteners. Proper alignment, securement, and quick assembly therefore is achieved.

摘要： A door operating mechanism for a bottom dump hopper car including a plurality of transversely mounted bottom discharge gates arranged in oppositely opening pairs and operatively connected by compression struts to pendulously mounted vertical levers. The levers are movable divergently outward by linkages connecting them to a lever mounted on a longitudinally extending rotatable actuating shaft. The invention further provides that in the locked position the vertical levers and compression struts be in an overcenter position relative to each pair of associated discharge gates, thereby assuring positive locking of the mechanism.
