`Thel crossA se'c'tionalfare'a of'y they casing at 'circular f andVL its juncturewith'the other-flat portion and consequentlyis positioned for receiving water'fr'om the pocket Al7through` the jet ori- .fices 18Hformed' in the said rib and being projected` therethrough annularly downward i into the blades `ofthe water wheel.A

The orifices are of ilarger diameter inside the` casing than they area-ththeir discharge ends and "if desired a vsmall li y 1 9' may be raised at'the advanced side Q each orifice receiving end to tend to facilitate thepasysage of waterv jinto the saidorifices 'to be directed forcefully'against/the water wheel blades, K i. i Sull/@ble [Supports -20fmayv be provided for supporting the casing upon the buttresses l and a bevel gear 2l may be `mounted on the shaft 4c and caused to mesh with ya bevel gear 22 on any suitable power take-off" shaft 23 .which may be equipped withA a take-off pulley 24 for applying the power setup by the rotating wheel to any desired practical use.

, By providing the casing scroll-shaped with its peripheral wall forming a true `circle and the gradually diminishing cross sectional area feature being provided for by changes in the v inner wall dimensions, a

more truly circular path for the inrushing water that will set up theleast possible resistance is provided', and by providing the flatfaces .forming the annularpocket the water will lbe naturally forced into the said pocketl by centrifugal force and delivered therefrom at its maximum force; Also by delivering the water from the greatest diameter Iofthe'scroll casing maximum leverage andmore power`v is obtained with a l minimum of friction vor other resistance.

By formingthe nozzles in the depending rib the power. applying water jets or nozzles are directed `toward the blades in a manner for utilizing the maximum of their power applying potentialities and` by rpositioning the blades as indicated at substantially right angle reversely kdirected positions .and by curving and sharpening edges of the blades into substantially axial alignment with the nozzles, means is provided for receiving the maximum force of the water jets without tendency toward waste or loss vof power` by waste of'water over the blades and between the wheel and casing.

While I have disclosed the wheel as operatingin ahorizontal plane around avertical axis it is to be understood that the same may be mounted to operate on a horizontal axis to rotate in a vertical plane without departing from the principles of the invention.;

lIf desired the rib through which the de-l V liveryy casing discharges may be formed on the outer or peripheralA flat face thereofl to discharge into a horizontally rotatable turbine wheel 25., Also, the discharge may be effected through slots 26 instead of the orifices if found practical. See Figures 7 and 8.

From the foregoing descriptiomtaken in connection with the accompanying draw` from the circularI portion and "joining to form an angle, an annular rib depending juncture. with theother flaty portion, and having nozzle orices therethrough to deliver' from one flat portion closely adjacent its having an entrant throat and a terminus and its cross sectional area gradually diminishing from the entrant throat to the terminus,

the peripheral diameter of said'casing remaining constant while'the remaining portions' thereof are diminishingto form thescroll.

In a device of the character described, a water delivery casing of the scrolly type having a cross Sectional area partially'circular and havingtwo iiat portions projecting from the circular 'portion and joining to form an angle, an annular rib` depending from one fiat portionnclosely' adjacent .its

juncture'with the 'other flat portion, and having nozzle orifices v'therethrough to deliver the water from thel angle formed by the flat portions through said rib, a rotatable water wheel having spaced ring wall s,"vanes Y between the walls land terminating s hortof` the tops of the walls to forman annular groove to receive the depending 'ribwliereby the nozzle orices discharge will be 'directed against the vanes to rotate lthe wheel. j v
