ABSTRACT:
An articulated connector for railroad cars comprises first and second connector members pivotally connected to each other at inner ends through a pin to permit vertical, rotational and horizontal pivoting of the connector members. The connector members have opposed ends proportioned to each welded to a railroad car sill. The articulated connector may be attached to a railroad truck which holds the connector and the ends of both connected cars. Pin bearing block means are carried in the articulated connector and abut the pin. Preferably, slack adjusting wedges are used to urge the pin against the pin bearing block, with the slack adjusting wedge means being laterally positioned in the connector. Side apertures are then provided for access from the exterior to the slack adjusting wedge means. Also, the inner end of the first connector may define a downwardly facing, spherical face which rests on a spherical recess area defined in the second connector inner end, with the connecting pin extending horizontally through the first and second connector member inner ends. By this and other improvements, improved wear resistance can be provided.
