gaat arpa,

fatina stata To attachant it may cimcera."` i `Be it jknown "that VI, AOLIvnn .MBoLn-iuenn, of Yoik, inthe county of VYork and State of Pennsylvania, have invented certai `iie'w'vand useful Improvements inlVater-Wheels;I a d`I do `hereby declare the following to he afull, clean-andfexact description. of the san1e,referencebeing had tov the accompanying 4drawings makingparltfof-this specification, in whiche- Figure lrrepresents, inperspective, the penstock for- `containing the waterwheel, or `in which the 1 wheel is placed.` i y `Figure2 represents, on an enlargedscale,`a vertical sectionlthrough thepenstockwaterewheel, `and gates.V Figure 3 represents` a horizontal section through tliepenstock, and withporftions ofv the wheel broken away to show parts underneath them.- ,i i j Figure4 `represents a view of the under` side of the top plate, showing 'the cams `thereon for moving the gates,` e j Figure-5 represents a diagrainshowin'g the centers from which the curves of the buckets or gates are asccrtained or'obtai'ned. y

`Similar-letters of reference, where they occur' in the several separate gures, denote like parts of the wheel and its co-operati've parts in all of the drawings.

My invention relates to'f that class `of water-wheels `wherein a" series of pivoted gates is used to open, i regulate, or close the inlet issues, and so regulate the amount of water to ,be `let'lonto the wheel; and l My invention consists, first, in curving the ianges j ofthe upper and under plates, orcroun-plate, and cyle inder, outsideot' the gates, sojas to make .the water# way at this point of greaterarea Vthan where it strikes thebnckets, andjthns increase its force, bydirninishl ing its volume area where it strikes the gates.

` ft further consistsin combining with a crown-plate whose exterior flange curves outward and upward, a deck-plate, with an outward and downward curved `ilange, tot thatof `thc crown or top plate.

g It further consists in conibining with an upper and an under plate, and a series of pivoted gates between' them, with studs thereon .projecting through slots in said upper plate', a deck-plate furnished with a series of cams, by which said gates may be operated.

lo enable others skilledin the art to make and use i myinvention, I will proceed to describe the same with referenceto the drawings.

The under plate or part of the wheel consists of a cylinder, A, which is vertical, and which has projectl ing from its'upper edge aflange," which is` first horiccntal, as at a, to a point or `line outside of the gates B; thence said iiange curves downward, as at I, and theneeliorizontah as at c, where it is supported by the penstock C,gandthroughrwhich iiange c the bolts that unite this under part with the crown-plate D also Ovei'the topplate rests upon said top or crown-plate, by means of its h .otivnafa terminera, or roux, rENNsYLvANIA. l

' pass, aswell as those which holdand adjust the, spiderE, thatsup'ports the water-wheel shaft Ffas at d.

the cylinder A, and belowits top there is an inwardly-proj ect- Onthe inside of portion a short distance,

i ing horizontal iiange, e, against the perimeter of which and the inner edge ofthe cylinder A the vertical and horizontal iianges f g of the water-wheel F run,'leav ing anannular space, 2, between thewheelfand the under plate,finto which the waterv finds its way, 4and aids to raise the wheel -on its step orsuppora The crown-plate D is recessed and shouldered,as seen in iig. 2, to receive the flanges upon the top H of the.\vater-`wheel. j

Outsidebf or beyond'these shoulders and-recesses the crownplate is horizontal, to-'a point as farout as the gates B'move or act, or nearly so, and thence it curves upward, as seen at h'h, and Vlugs, a', c' project beyond the curve h, to receive the bolts that unite it to the under part or plate, and that support the spi# der, and through it the wheel itself.

The gates B, of the form and construction shown in igs. 3 and 5, are pivoted, as at n, to the top and bottom .platesof the wheel, and upon the upper edge 'of'each gate there is a stud, m, which projects through a slot, o, in the top plate, D, there being a stud and;

slot`for each gate.

D there is a deck-plate, G, which hub j and its downwardly-curved exterior flange-k, leaving a space or chamber between said crown and deck-plates for a series-of eccentric -iianges or cams, r fr, which are `made on the under side of the 4deckplate G, to project and operate in,'as will be explained.

A` shaft, l, is supported in the top and bottom plates of the wheel, and extends up vertically throughV the penstock C, and has at its upper end a hand-wheel, p, or other device by which it can'be turned.4 On this shaft there is a pinion, q, which works into a segmental rack, s, attached to the deckplate G, so that said deck-platemay be moved to open the gates B, which is done bythe cams lr taking against the studs fm, and turning the gates on their pivots. #The gates are closed by the action of the water against them, as vthe portions of them that are beyond their pivots and next the vinrushing water are Ymuch longer than Athe other portions between sa'd pivots and the wheel proper, so that the pressure of the water upon these longer portions constantly tends to close the gates, while they are opened and held open by the cams r. Each gate being independent of the one or more ofthe gates may be clogged by anything getting in and there remaining, while the others may all close, which'would not be the case if they were closed by a positive or arbitrary movement ot" the disk or deckheel G. But while these buckets are other in closing,

'tinued m opening that individual y self-closing by the pressure of the water upon ther longer'ends, yet by an extended ,or oonavement ot the deck-plate they maybe closed by said deck-plate.-

It will perceived'that t anges, h f plates to 1e cul-vi o the erownand deck-plat by a horizontal joint. partcula' ijeot of thisro'r f ed 1 i is, in con eff' 1n with the under n" i ange b, to form a Haring water-way or inlet passage, unbroken by angular or square corners, which,l however obtuse, will break up the regular inflow ot water, and` detract from its normal force, which rounded surfaees will not do to so great an extent.

On the crown-plate D'ofthe wheel there s a hol low shaft or tube, t, which vextends up through the penstook and has on its upper end an adjustable bearing and oii-bc x, I, for supporting and truing the upper part of `the wheel-shaft F.'

' The deekpieces G 'O' of the 'penstoek` are cli or sectional, so that access may he had through the they cover to the wheel; and for the purpose of getting at or into the. wheel, to clean it out or otherwise `an opening may be made-through the case or 1 so as to draw ont. the pivots and stud of one of hebuckets, and thus remove said bucket, whio :es au avenue to the wheel, and any part ofthe w heel may he turned round to this avet g -oi' the tufo' es, allows these But the more of the plates nue. The u i gs for drawing ont'the pivots, 8vo.; eau be closed by a screw, cap, or otherwise.

The holes u in the top plate of the water-wheel, as

yshown at H, are for allowing the water that leaks a point, theywould touch the wheel at apoir Afu, but they are out ofi atv a point, w, so that through-the joint between the wheel and the gate or crown-plate to pass out, otherwise it would be forced up through vthe tube t.

If the gates B,as seen in fig. 5, were f-x niet] t0 ma. all

the

and

What I elainmand desire to secure byk Letters Pat- The upper and under plates, curved beyond the gates, as at b It, for the purpose ot' making a flaring and rounded inlet furthe water, as and fo'rth'e'purpose described. f

Also, in combination with the crown Bange h the deck-plate and its flange It, off the junction ofsaid plates, as andpose described. l

in combinat on with the series stu ds m, (said gates being arrangei f "y plates and the studs m proj i plate ofthe m0,.) the movab cams r, for ing said gate' bed and rep plate audits for rounding for the puretween the g through eek-plate G substantially" rked the.
