Fig 3 shows one ofthe latest trucks manufactured by theJ. G. Brill Company. The truck consistsof the side frames (1), which are tiedtogether by the end frames (2), and thetransom (3). Equalizer bars (4) andequalizer springs (5) are used. Betweenthe sides of the transom (3), which aretied together by the transom tie bars (6),is located the bolster (7), on which ismounted the center bearing (8), and theside bearings (9). The bolster is carriedon the bolster springs (10), so that sameis free to move and the vibrations of thetruck are not carried to the car chafing plates (11) and transom. GIBBS SUSPENSION^. tion by means of springs is made to theparallel bars. GIBBS SUSPENSION. Fig. 2 illustrates this form of motorsuspension. Two side bars (K), one oneither side of the motors, are joined to-gether across the ends by the bars (L).The frame of each motor is fastened tothe side bars at M. The back side ofeach motor is provided with a lug (N),which is fastened to the bar (L) by bolt(O) with springs (P) and (R) to takeup the vibrations. Referring to the figure, chafing plates (12) are fitted to the truckto receive the wear. The bolster springs (10) rest in bolsterspring seats (13), which are carried onthe spring plank (14). This spring plankin turn is held up by the transom bymeans of the hangers (IS). CROSS-BAR SUSPENSION. We now come to consider the modernmethods of suspension, of which this isone. It is really a modification of thecradle suspension. Referring to Fig. 1,
