Repairing Locomotive Driving Boxes Brasses Cast in Place are Better Bothas to Service and Cost of Repairs BY M. D. FRANEY, Master Mechanic, Lake Shore & Michigan Southern, Elkhart, Ind. The design of the driving box and its associated parts, themachinery available in the shop, its relative location, as well asthe organization of the shop have an important bearing on theproper method of repairing driving boxes. In the followingstudy of the subject the functions of the driving box and itsassociated parts will be considered first and will be followedby a discussion of the proper method of making repairs. The ideal driving is one having a general construction ofample strength to permit maximum wear and the restoring of. Pacific Type Locomotive. worn parts to their original dimensions. It should give themaximum service between general shoppings with a minimumamount of repairs. The following items affect the service andrepairs; wear between the journal and the brass; the secureholding of the brass in the box; lateral wear between the drivingbox face and the driving wheel hub; securing and holding of thehub liners in the boxes and on the driving wheels; reducing toa minimum the wear between the shoe and wedge face and thedriving box. The wedge bolts should have ample strength anda liberal bearing area between the bolt and the wedge. Theflanges of the driving box for shoe and wedge lit should betapered to prevent the raising of the brass from the journal, orthe binding of the driving box and shoe and wedge during therolling of the locomotive in service. Experience proves that the wear on the main driving journaland brass is more rapid than on the front and back wear may be
