The method of giving a current in the same direction on both the flood and ebb 20 tide is now to be described. The single tide gate I, Fig’. 1, is shown, in th~ figure, as hung to a competent suppor~ in the bank or wa~ at A, Fig. 1, and closed against the inner dam wall D. admitting the eurren~ of 25 the N~ng’, or flood fid~ from the fide NdeT. of the dam wall C, to run through the race E. and carry the wheel I-I, in the direction shown by the arrows 12; the outer curren~ gate X, is shown, shut. from the outer dam wall C, to a shutting jamb fitted to receive g in the bank or wall a~ B, Fig’. 1, where it is kep~ by the pressure, caused by the external, or tide water, at T, being higher than that in the miH pond at ~. the inner eurren~ gate L, being open, to pass the water from the race ~o the pond M, so that the eurren~ running through the race E. ear- ties the wheel H, as shown by the arrows 1~, Fig. 1, and fills the pond M, supplying a water power to run ou~, when the external and forcing the water from the pond side M. of the dam wall D, to pass out. as the tide falls, in the direction.of the arrows 13, the inner eurren~ gate L is shown as closed. to prevent the water in the pond, passing by .that end of the inner dam, and will re- mam shut, by the internal water, so long as that in the pond M. is higher, than the 4xternal, or falling fide water, at T, and the outer eurren~ gate K, is shown as open, In fitting the caissons, I do not mean to confine, or limit myself to the mode shown. use any other convenient mechanical means, Of flotation than is required, a small eoek may be fitted, to adm~ so much watch as is needful m load the caissons to the required 3O 35 40 45 50 55 60 keep any such leakage pumped out; and as before premNed I do not intend to confine. or limit mysel~ to the construction of dam~ whose length shah be only competent to receive one whe~, with its equipments, bu~I 75 intend to make the double dam walls, and miH race as long’, as the localities of situa- tion will allow, and work any number of whe~ that the dam wal~ w~l receiv~ plac- ing the tide gate at one end, and the current s0 gates at the other end of the dams, whatever fl~eir length may be. It will be seen, that with any number of wheels, thus fitted, no interruption will take place in the work, ex- cept at the dead low wate~ or high water s5 of each fide, for the instant the water, on either side the dam~ is higher than on the opposite side the-tide gate I, wiH go over ~o, and close on, the lowest Nde, and the like effect will take place with the current gate, on tha~ Nde, the other current gate opening, to pass the wate~ so that the operations of the tide, alone, will change the gate~ and set the whed, or wheels, in work; and it will be seen, that in cases, where the wheel race 95 shall be over about twelve feet wide, it may be proper to make the tide and current gates i,~tP ~:~’ whiCheffectivemaY bemanner,d°ne’ inand theanY pro_e°n" por~on~ between the width and height of chosen, and the rise and fall of the tide, in the given locally. It may be prope~ to protect the tide and current gates from 105 wrecks, or drift wood, on the tide side of the dam, but many well known modes can manual attendanc~ to open and shut them, at the.turn of the tide; but no tide mills have. to my knowledg% been proposed, or made. with three sel~ acting gates, and lon- or wheds, and maintain an equality of powe~ during the flood and ebb; and al- ~1 eo~iinn, tiaethereforeraees’Iin thelimit gate I, at one end of a race way~ formedby i00 115 120 125 130 an inner and outer dam wall, in combina- I 3.
