A railway coupler arrangement which eliminates the conventional yoke strap, thereby enabling a larger draft gear to be employed in the coupling without increasing the overall size of the sill. The invention also provides a novel assembly for facilitating a rotary coupler arrangement in which the diameter of the rotary shank can be increased over prior art rotary butt couplers.

Railway coupler arrangement

The present structure provides for a plurality of members for maintaining a pair of laterally spaced side frames of a single axle truck in a squared relationship. The members are joined to the side frames by detach-safe connections, wherein latches are formed at the ends of the members to seatably engage with notches formed on brackets of the side frames.

Single axle truck transom assembly

A railroad vehicle truck having a single wheelset includes a pair of spaced side frames. The side frames are joined into a rigid unit by a pair of transversely positioned crossbars. The crossbars are positioned one each on each side of the wheelset which has its axle ends journaled in bearings carried in turn in a pedestal jaw centrally formed in each side frame. Projecting inwardly from each end of the side frames is a bracket which forms part of a set of upper pivot connections with an upper end of a swing arm. A laterally positioned crosstie assembly is joined through a pair of spaced end caps with a lower end of each swing arm to form a set of lower pivot connections. Each crosstie assembly end cap has a pair of spring cups containing a set of springs which operatively support a body of the railroad vehicle thereabove.

Single wheelset railway truck rigid transom connected sideframes

A side frame for a single axle railway truck is provided. The side frame has top and bottom and spaced side walls. The side frame has a generally hollow cross section, with an upper middle portion, downwardly sloped intermediate portion and lower outer portions. The top and bottom walls have decreasing thickness inwardly from the end of the outer portions.

Single wheelset railway truck sideframe

An improved railway truck friction shoe is provided. The contact point of the shoe slope face with the bolster and the spring center line of the shoe are substantially coincident; the contact point is substantially equidistant from the top and bottom edges of the shoe column face. The convex sloped surface of the shoe has a reduced crown radius, and the vertical face of the shoe has an increased length. The shoe is designed to provide a more even distribution of contact pressures across its column face. This results in a longer wear life for the shoe by providing for more uniform wear.
