When the wheel is in operation, the water thatleaks through between the rims, M /, acts upon thebuckets, L, and thus aids in driving the wheel. Bythis arrangement much friction is obviated, as therims, M /, do not require to be brought in close con-tact in order to form a water-tight joint as hitheito. By the employment of thevalve, F, the water inthe penstock, D, is made to leave the penstockentirely when the gate is closed, the vacuum whichwould otherwise be produced in the1 penstock on thewater leaving it being prevented by the opening ofthe valve by the external pressure of the atmosphere.By removing the nuts of the screw bolts, a, the wheelmay be readily withdrawn from the penstock and allof the parts rendered accessible for repairs. The patent for this invention was granted throughthe Scientific American Patent Agency, July 24, 1860, and further information in relation to it maybe.
