TRACTION RNCINKS 439 upon it. It is ob\ioiis that this puts undue strain uponthe boiler shell at a point where it is the weakest. Theweight of the boiler and the engine is thrown upon thesebrackets and in such a manner that it has a tendencyto throw the inside of the axle down and the outside will tend to throw the tops of the drive wheels to-gether and the bottoms apart. The weight is also throw^nupon these axles so that that part of the hub of the fly-wheel next to the engine will wear faster than the -middle,and as a result the wheels will tend to become wobblyin action and wear the teeth of the transmission gearingunevenly. A truss bar similar to that of Fig. 318 re-moves a great deal of the strain from the water leg, and
