. Railway mechanical engineer . a. May. 1910 RAILWAY MECHANICAL ENGIN 225 or within the two steel pieces. When the rod is deflected fromthe normal position, the spherical bushing allow- the partsto rotate sidewise around the center of the front crank pin;at the same time the bushing can revolve cm the cylindricalportion of the pin. Several oil holes are provided throughthe bronze bushing to insure lubrication of both the sphericaland cylindrical surfaces. The operation of the lateral motion axle should be con-sidered in connection with the engine truck. The driving. Lateral Motion Device Assembled on the Axle springs of ihe hr-t and second axle- arc equalized in the-usual manner with the engine truck; therefore, the weighton the engine truck center pin and the lateral motion boxeson the first axle is divided in proportion to the arms of thefront equalizer. The engine truck is of the inverted rockertype, having a resistance of 50 per cent against the initialmovement, and. as previously stated, the resistance of thelateral device at the first driver is 20 per cent. These re- lateral resistanci is applied in the plane of each wheel in-stead ot being applied midway between the wheels and <livided between them as in the case of a four-wheel tank. Asfar as guiding the engine is concerned, therefore, the arrangement is very similar to a four-wheel application wit)rear wheel of the truck acting a- a driving wheel. ihe resistance of the lateral motion box is proport oner]with the idea <11 providing enough initial resistance so thatfor any ordinary r
