The main members of the underframe are 15-in. center sills, with 3^-in. by 3J^-in. by 3/g-in. angleside sills. The inside longitudinal hopper sheets are madein one piece for each set of hoppers flanged outwardly. Whereeach sheet passes up over the center sills the flange is rivetedto that of the adjoining hopper sheet and the sheets are rivetedto the sides of the center sills. Of the lower flanges oneforms a surface against which the door clcses, while the otheracts as a support for the end hopper sheet. This sheetpasses up over the hinge angle, giving the proper finish overthe door of the next hopper. The outside hopper s
