The motion between the cats, due to their approaching and receding fromone another, is allowed for by the swivel-joint and the cross-pipe C. As the cars approach, the swivel-joint comes intoplay, the cross pipe moves in an arc, and the motion of the caris thus allowed lor. As the cars recede, the same thing lakesplace^only the cross-pipe moves in the opposite direction. It will be seen that the swivel-joint mechanism suppoitsthe cross-pipe and the ball-and-socket-joint mechanism withoutrequiring special supports for these parts from the car-body,which is a difficult matter to accomplish. When the cats areseparated, the only part of the apparatus which hangs downtoward the ground is the
