However, theshoes for the leading truck should cover not only theouter tread but the flange also of the wheel in order toreduce to a minimum the tendency to sharp tender shoes, if used on steel tires, should prefer-ably be made of the same design, although the tend-ency toward wearing the wheel flanges sharp is not sogreat as in the case of the engine truck. The shoes ineach case should have good frictional effect consistentwith the proper action on the tires. THE SARGENT BRAKE SHOES. The Sargent brake shoes, made under license fromthe American Brake Shoe Company, are described asfollows: Locomotive Driving Brake Shoes. — First, the LOCOMOTIVE APPLIANCES. 71. Fig. Steel Brake Shoe. skeleton steel brake shoe, Fig. 2, is a casting ofmild steel, the metal of which isso disposed as to cover as muchas possible those parts of thewheel tread which are not actedupon by the rail. Steel is themost effective metal for wearingdown the tire and in the skeletonsteel brake shoe the right metalis properly designed for the service required. Thematerial possesses high f rictional power and a strongwearing action on the tire, and, as distributed in theskeleton design, cuts away the outer tread and top offlange, thus tending to maintain the original tire out-lined. Shopping engines for tire turning is largelyprevented or delayed by the use of the steel shoe, andthe expense of locomotive maintenance considerablyreduced. The skeleton steel brake shoe is stronglyrecommended for freight, switching and suburbanservice, and where tires are rapidly worn into by theaction on the rail. The Skeleton Steel Insert Shoe, Fig. 3, is recom
