A piston rodextension to be satisfactory must be of simple yet rigid con-struction, easy to lubricate and easily removed without interfer-ing with other parts of the locomotive; above all, it must havean ample bearing surface, a feature which was lacking in all ofthe earlier designs of piston rod extensions. A superheater can be successfully applied to any of the existingtypes of locomotive, provided they are equipped with piston gaging point / is moved against the flange. The amount ofwear is indicated on the scale E, which is divided into divisions1/16 in. apart. The deptli of wear of the tread is measured by the scale F,which is free to slide up and down in the part A. The limitsof flange wear may be determined by using the gage
