The draft bolt connecting with the coupling makes aball-and-socket joint, as will be observed by examinationof fig. 3. Fig. 4 is a view in perspective of the couplinghook, and showing means of coupling with link and pinwhen brought in contact with that class of coupler. Substantially this mechanism, as above described, wasthat which Miller brought his suit against. In some cases the cars of the Pennsylvania Railroadused springs surrounding the buflfer-shanks instead ofusing the single spring C, but this was the first arrangementand was probably suggested by the Cummings patent, andwas soon abandoned for the structure shown in the abovecut.
