摘要： A specially configured insert used in a drawbar support housing. The insert is essentially a block member having at least a portion of an aperture extending therethrough from a front face to a back face. A concave draft load bearing surface is formed in the front face of the block member adjacent such aperture. A tapered surface area is formed adjacent such aperture which extends from the back face of the block member inwardly towards the concave draft load bearing surface to enable requisite movement of a shank portion of a drawbar.

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 rotary railway drawbar coupler is provided which comprises two elongated shank members each having a convex butt surface at one end and a generally circular butt surface at the other end. The two elongated shanks are positioned between the two railway cars being coupled such that the circular butt ends are adjacent each other. A connecting collar surrounds the circular flange of which the circular butt surface is a part. Each elongated shank may have a longitudinal cavity extending inwardly from the circular butt surface to accommodate a cylindrical bar that extends between the elongated shanks.

摘要： The present invention provides a method and apparatus for reconditioning a draft gear assembly friction clutch mechanism. The apparatus comprises a generally rectangular substantial flat plate member having at least one protuberance extending outwardly from one side of such plate member. The friction clutch mechanism reconditioning method includes the steps of removing each component of the friction clutch mechanism from an open end of the draft gear housing. Then engaging the plate member with an outer surface of one of the outer stationary plates of the friction clutch mechanism in a position such that the protuberance extends into a recess on the outer surface. Thereafter reassembling the friction clutch mechanism into the open end of the draft gear housing in a position such that an opposite surface of the plate member engages a portion of a wall surface of the housing.
