The forest of shores will be noticed inside of the ves- sel during construction and how much could be saved by having 'the material all made from the mold loft. Fig. 168 shows the boiler room with the seatings completed for the boilers, as well as the great number of shores sup- porting the decks. The. shell plating runs an. inch thick and has an average width of five 'feet amidships; it is lap-butted and almost entirely quadruple riveted. The four top side strakes of the plat- ing of the hull are double strapped, and quadruple riveted. Within the range of the double-bottom the shell is also double-strapped, treble riveted inside, and double riveted out- side, and the butts of the keel plates are treble riveted. : Wherever possible hydraulic riveting was resorted to, and even before. the rivets were put in the plates and angles were forced and held together by hydrau- lic power, so that the temporary bolts and nuts would bring the surfaces as closely together as possible before rivet- ing. In this way there was absolutely no possibility of yielding when the riv- ets were put in. The work done by -hy- draulic power includes the center gird- er, keel-plate garboard strake, the center strake of the inner bottom, the intercos- tal girders, the end frames to the reverse angles of beam-knee brackets, 'the bridge-- Fic, 164. deckshear strake, the shelter-deck string- er angles, and the side stringers between top and erected with gin poles as shown by Fig. 159. Fig. 160 shows the erecting of the side framing, which is conposed of chan- nels nine inches deep amidships, and an- gles and reverse bars at the ends. The frame spacing is 32 in. amidships and 27 in, at the ends. The belt frames are spaced six frame spaces apart beyond and five frame spaces in the boiler and machinery' spaces. : Belt frames are 30 in. deep and % in. thick, with frames double to shell and heavy face bars continued from tank top to main deck. The bottom, framing is composed of floor plate and angle; the angle is joggled over the shell plating in- way of the inside strakes in the double bottom. The beams are erected along with the frames, as shown by Figs. 160, are 161 and 162. : Bere ee : Fig. 161 shows the engine room with pen os Big. «1650 ca pe framing up abaft same.
