The application of the chain suspension to both passengerand freight connector heads, by which accurate verticalalinement of the head is assured while in its free position,is shown in the drawing and in one of the photographs. Byreferring to the drawing it will be seen that the length of. Application of Freight Connector with Chain Suspension;Interchange Adapter in Service Position the chain is so adjusted that when the head is free the centerline of the connector is raised at an angle such that the noseof th( projecting guide is held % in. above the horizontalline through the pivot center. In this position the bearingface of the connector head projects l]^ in. beyond the insideface of the coupler knuckle. The angle of the chain is suchthat when connector equipped cars are coupled the slack pro-duced by the 13^2 in. compression gives the heads completefreedom of angular movement within the full range of move-ment of tlie car couplers, both angular and vertical. In passenger service the use of high steam pressure on thesteam heat line, particularly between the locomotive and abaggage car equipped with head end lighting equipment,produces a severe reaction tending to separate the heads un-less springs of higher capacity than those used in
