his is constructed of plate iron three-eighths of aninch thick, riveted together. The supply pipo is furnished with the man hole and ventilating pipe G,and the leak box H, to catch tho leakage of tho head gate, whenever it is closed for repairs of thewheel. The lower end of the supply pipo is formod by the cast-iron curbs III. Tho curbs aro supportedfrom the wheelpit floor by four columns, resting on the cast-iron beam O; tho beams N, rest immedi-ately upon the columns, and the curb upon tho beams, tho latter projecting over tho columns far enoughfor that purpose. Tho beams N also act as bracos from tho wheelpit wall to tho curb, and aro strongwbolted at each end. K, the disc. This is of cast-iron, and is turned smooth on tho upper surface, and also on its circum-ference. It is suspended from tho upper curb I, by means of tho disc pipes M RI. The disc carries onits upper surface, thirty-three guides, (fig. 3816,) for the purpose of giving tho water entering the wheel 884 WATER-WHEELS.

WATEK-WHEELS. 885 proper directions. They are made of Russian plate iron, one-tenth of an inch in thickness, secured tothe disc by tenons, riveted on the under side. The upper corners of the guides, near the wheel, areconnected by the garniture L, which is intended to diminish the contraction of the streams entering thewheel, when the regulating pate is fully raised. The garniture is composed of thirty-three pieces ofcast-iron, carefully fitted to fill the spaces between the guides; they are strongly riveted to the guidesand to each other. The upper flange of the disc pipe is furnished with adjusting screws, by which the weight is supported upon the upper curb. The escape of water between the upper curb and the upper flange of the discpipe, is prevented by a band of leather on the outside, which is retained in its place by the wrought-iron ring P. The top of the disc pipe, just below the upper flange, has two wings, fitting into recessesin the top of the curb, to prevent the disc from
