T0 ALL WHOM IT `MAY CONCERN: p

Beit known that I, JACOB JOYCE, of Dayton, in the county of Montgomery, and State of Ohio, have invented certain new and useful' Improvements in Water-Wheels; and that the following is a full, clear, and exact description ofv the same, reference being had to the accompanying drawings, making a part of this specification, in which i Y AFigure represents a vertical section through the whcel,ease, and regulating-chute cylinder.

Figure 2 represents a horizontal section through the same, taken at the red line ai :c of iig. 1.

Similar letters of reference, where they occur in the'separate iigures, denote like parts of the wheel in both oft-he drawings. i

I am awaretliat many ways have been devised for directing and regulating the inow of water to a waterwlieel. ,Of course Imake no claim to this in any broad sense,rbut believe that I have invented a plan of so directing, introducing, and regulating the quantity of water let on to a water-wheel, that is cheaper and better thanany other plan knownto me.

In addition -to the plan of regulating and directing the indow of water, I havedevised a plan of relieving the escape or` dischargeof the water from the Wheel after it has expended its force uponit, and this, too, without interfering-with the ttin'gipfthe wheel in a lathe, which cheapens its construction, and causes the parts to movcwit-limore accuracy, as. thejoints are thus more truly made. i

My invention consists in the use of a stationary case, furnished with a series of openings, and interposed between the adjust-able or turning-gates or chute-case, and the wheel proper, for the purpose of directing or regulating the'inow of' water upon the wheel, in combination with the constructing of the wheel proper of a cylindrical form and with aperpendicular exterior,` for readily turning it off in a lathe, and with a hollow conical interior for'the better or more free discharge of the water after'it has been expended upon the wheel.

' 'loenable others skilled in theart to make and use myinvention, I will proceed to describe the same with reference to the drawings. Y f

The wheel A is of the double turbine centre-veilt kind, and secured to its shaft B in any of the usual well* known ways, andthe shaft supported in a bridge-tree, 0, as is common in such Wheels. The exterior, a, ofthe wheel A is cylindrical, so that it ma be readily turned-oil' in a lathe. The-interior ofthe wheel is conical, and the top, bottom, and central rims or rings 1, 2, 3aroparallel,'or nearlyso, and are Vinclined in a downward direction from the exterior towards the interior of the wheel, as clearly shown in ig..1. The Object of the-conical -form' oi' the interior of the wheel is to enlarge the dischargespace orvent from the top to or towards the bottoni,

'and allow the water to freely escape after it has left'the buckets.v Below the wheel isplaeed the usual suction orldraught-cylinder D, which is a part of the register-.case E, as said cylinderfcase and Vflange F, ars'jwell as, the header top-plate, I prefer to cast-in one piece,rand to turn oiiand fit up at one time in ailathe. "The rijm of the wheel A runs close to the interiorof the vertical portion ofithe case E', and quite close tol the Aurldl s l Df the head or top plate Gr, which is aclose plate, having no free openings. The shaft B of course passes through this head ortop plate, but is packed. The cylindriealportion E of the case is furnished withaseres of openings c c @which are. as longr as the whcelmis high, and through which the wat-er passes to reach the buckets of the l wheel. Around the exterior of the stationary case E, and resting in whole or in part upon thellange F thereof, orp'artia'lly on the {lange and partially by the projection d, extending over on to the top plate (ih-the chute or gate-rim' or cylinder H is placed. This chute or gate-cylinder has a series of guides Ve e arranged upon it, so as vto `form a series of chutesff, corresponding to the number and size of openings c in the ease E, and the dead spaces g, between the ehutesf, ae of suieient height and width to cover the openings c when moved over them.

The A'gate or chute-cylinder-hms upon it a-curved rack, h, into which a spur-gear, z', on the shaftj takes, and-by turningsaid shaft or gear the gate or chute-cylinder can be turned to open o'r close the water-ways c, and regulate the inflow at pleasure, or cut'ito entirely, as the case may be.

Whether thc'guides e are used or not, the wheel Ais made with two tiers of buckets 7c Z, so arranged that the upperones, c,will alternate in position with the lower ones, l, as shown.y By means of thisalternate arrangement of the buckets placed intiers, and the use of the `openings e, in the case' E,extending the Ventire depth of
