摘要： A railway car with a slackless drawbar arrangement for unit trainservice and the like is provided and includes a drawbar having a section which is fabricated. The fabricated intermediate section is cut from a section of seamless pipe or tubing or can be fabricated from plate, while the coupling end pieces attached to each end of the shank are cast members made from typical casting methods. The coupling end pieces can be cast into standard fixed or rotatable drawbar ends or even be a combination thereof with rotational capability. The geometric shape of the intermediate section is varied, depending upon the application, so that resistance to torsional or bending loads is maximized. The fabricated shank portion is hollow, as well as part of the body of the coupling end pieces, thereby reducing the railcar's weight and costs to manufacture.

摘要： A draft gear assembly is disclosed alone and in combination with a draft sill and a coupler. The draft sill has front and rear stops defining a draft gear pocket. The draft gear assembly has a yoke, a coupler follower, a rear follower, a front resilient member and a back resilient member. The yoke has top and bottom stops. The coupler follower is biased against the yoke top and bottom stops. The draft gear assembly also includes a center rod that extends through the yoke, through the back resilient member and through the rear follower. Prior to installation on a railcar, there is a shortening member on the center rod. The length of the assembly between the shortening member and the front of the coupler follower is slightly less than the longitudinal length of the draft gear pocket. After installation, the rear follower is positioned against rear stops of the draft sill. After installation, the yoke, coupler and coupler follower each have a neutral position and a full buff position. The yoke and coupler also have a full draft position. The draft stroke of the coupler and yoke is 1¼ inches forward. The buff stroke of the coupler and coupler follower is at least 4¼ inches rearward, while the buff stroke of the yoke is 3 inches rearward. The center rod is free from compression throughout buff movement and free from tension throughout draft movement of the coupler and yoke.

摘要： A draft sill end casting with a locking center pin is disclosed. The draft sill has an open member with an elongate channel aligned with the central aperture of its center plate. A support shelf is within the elongate channel. A center pin has an upper retainer key supported on the shelf, and the center pin extends through the elongate channel to the exterior of the draft sill. The lower end of the center pin has a slot. When mounted on a truck bolster, a lower retainer key is slid through slots in the bolster walls and through the slot in the lower end of the center pin. The two retainer keys, support shelf and bolster walls lock the center pin in position, limiting axial movement of the center pin and limit rotation of the center pin. Thus, the draft sill and truck bolster are locked together to limit relative vertical and horizontal movement between them. The shelf may include rotation stops to limit rotation of the upper retainer once it is in place. The draft sill includes a key passage so that the upper retainer key and center pin can be removed if desired. In two embodiments, the key passages are through the support shelf and lead to the exterior of the draft sill; in these embodiments, the center pin and retainer key can be removed from the draft sill as a unit. In another embodiment, the key passage is formed as a slot in the interior wall of the draft sill above the support shelf; in this embodiment, the retainer key and center pin must be removed independently of one another.
摘要翻译： 公开了一种具有锁定中心销的通风口端铸件。 通风门具有开口构件，其具有与其中心板的中心孔对准的细长通道。 支撑架位于细长通道内。 中心销具有支撑在搁板上的上保持器键，并且中心销延伸穿过细长通道到通风门的外部。 中心销的下端有一个插槽。 当安装在卡车垫上时，较低的固定键可滑动穿过垫板壁中的槽，并穿过中心销的下端的槽。 两个固定键，支撑架和支架壁将中心销锁定在适当位置，限制了中心销的轴向运动并限制了中心销的旋转。 因此，挡泥板和卡车垫子被锁定在一起以限制它们之间的相对的垂直和水平移动。 搁板可以包括旋转止动件，以限制上保持器一旦到位就可旋转。 通风门包括一个钥匙通道，以便如果需要，可以拆下上保持器键和中心销。 在两个实施例中，钥匙通道穿过支撑架并且通向通风门的外部; 在这些实施例中，中心销和保持器键可以作为一个单元从起草条上移除。 在另一个实施例中，钥匙通道形成为在支撑架上方的通风门的内壁中的槽; 在该实施例中，保持器键和中心销必须彼此独立地移除。

摘要： The present invention provides a lightweight draft sill end casting for use with railroad cars. The cast draft sill has side walls, front and rear stops, front and rear rib sets and a center plate that are cast as a unit. The draft sill has an open area between the tops of the side walls between the front and rear stops, with a cast metal span connecting the two side walls. The cast metal span may comprise one or more spacer bars or part of a top wall. The cast metal span is in the area between the planes of the front stops and the rear stops. The front and rear stops are spaced below the tops of the side walls. In one embodiment, there are additional lightener holes in each side wall between the ribs in the rear rib set and in the pocket. The total weight of the cast draft sill is not substantially greater than the weight of a comparable fabricated draft sill of substantially the same size, and has a greater fatigue life. The total open area connecting the interior and the exterior of the draft sill between the front stop plane and the rear stop plane is at least 130 square inches.

摘要： A latch lock mechanism for a railcar rotary-dump coupler is provided for an Alliance coupler having a more narrow inner housing cavity for the coupling mechanism than the standard coupler housing chamber, and the latch is operable to extend from a locklift assembly at a coupler and railcar inverted position to contact a top wall recess of the cavity to constrain the locklift assembly from movement past the lock thrower to thereby constrain movement of the lock thrower and coupler head, which latch maintains the coupler in a closed or coupled state at the inverted position.

摘要： A railway car coupler includes a knuckle that is rotatable about a pivot pin. The knuckle is comprised of a tail section, a hub and a nose section. The knuckle is usually made of steel in a casting operation. The pivot pin opening in the knuckle is cylindrical with generally straight walls with a reduced diameter centrally located cylindrical relief area. The nose has a blunt end, and a thicker internal reinforcing section is made by having an end of the face core extend a lesser distance toward the pivot pin opening. The transition area between the tail and the nose is formed by parabolic shaped upper and lower sections.

摘要： A railway coupler is provided having a coupler head comprising pulling lugs, behind which compound fillets of variable increasing radii have been inserted. The compound fillets reduce the stress concentration behind the lugs by distributing load over a greater curved surface area in order to decrease the possibility of fatigue cracking and failure of the pulling lugs.
