Abstract
An articulated coupling apparatus utilized in connecting together, in a substantially semi-permanent fashion, adjacently disposed ends of a pair of railway cars includes male and female connection members. A front and rear followers, each having a spherical cavity, are positioned within the female connection member. First and second lubricating liners are positioned within such spherical cavities and a spherical member is operably caged between such lubricating liners. A shaft is attached to the spherical member and extends outwardly from the female connection member for secure connection to the male connection member. A pair of wedges are mounted adjacent the rear surface of the rear follower and exert a force onto such rear follower moving it toward the spherical member and further toward the front follower to compensate for wear of the mating spherical surfaces during service and to prevent formation of a gap between the mating surfaces.
