A cast steelcenter casting fits between the center sills and is held by four ofthe same rivets securing each diaphragm to the sills. A flanged5/16 in. plate, 4^ in. deep, forms a backing and stiffener be-tween the diaphragms just above the side bearings. Between the bolsters there are three single deep diaphragms,between the side and center sills on each side of the same sizeand shape as at the bolster; also four flanged intermediate cross.

Although the unloading is normally to be done by machinesit was deemed advisable to furnish four small bottom doors,which close flush with the floor, for use on the ordinary type ofccial pockets. These doors are arranged two on either side andstaggered as shown in the plan. Considering the details of the design, and referring to the ac-companying illustrations, it will be seen that the center sills con-sist of two 15 in., 40 lb., channels set back to back, about 13 and extending continuous for the full length of the hese are reinforced between the bolsters by a y/z x 3 in., , angle riveted opposite the lower flanges and a 20 x 5/16 cover plate also extending between the bolsters. The sidesills consist of a 10 in. built up channel, the web of which isformed by the ext
