ABSTRACT:
The stops of a draft gear housing of a rail car central coupler have to meet relatively large tractive and compressive forces in service. Up to now the expense involved in the fastening of such stops has been very great. In many cases, where the stops or bearings were joined to the center or stub sill, cracks formed and/or the sill became deformed. This incurs considerable expense for repairs and means a loss of service while the vehicle is being repaired. In accordance with the instant disclosure, to avoid such problems the center or stub sill of the rail car is now made such that the front stop and the rear stop are integral parts of the sill.
