IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same To all icliom it may concern Be it known that l, JACOB M. (Joon, of Lake \'il lage, in the county of Belknap and State of New Hampshire, have invented an Improved \Vater Wheel; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying?r ldrawing making part of this specification- Figur'e 1 being a lop view of the improved waterwhcel.

Like letters designate correspondiner 'parts in all of the figures. A

The tirst feature of my improvement consists in the construction of the top, a, oi' the case, A, with a cenral opening therein large eimugh to allow the top to come oli over the shalt. o, of the wheel, without rcmorin the couplinf,r therefrom, or any pullcy or gearwheci, if used thereon, and in covering this opening with a removable cap ur dome, l, made in two parts, so that it also can be removed from the shaft C with-' out relooking the coupling thcrcii'om.

This cap or dome forms the upper bearing of the shaft, is provided willi a soft metal bush, and has a stalling-box in it, so as to he. water-tight around the shaft.

The two parts oi' the cap or dome l, which covers the central aperture in the top Il, have respectively flanges, b b, on their contiguous edges, by which they are secured together with screws, c c, so that the cap can be taken apart and removed from the wheel-shaft C whenever desired, without disturbing the coupling or connecting gear of the shalt above it. The cap also has a flange on its lower edge, by which it is secured to the top cy with screws tl 1I, so that, ou removing, the cap can he removed from the. wheel-shatt without hindrance.

The bearing in the cap is lincd with a soit metal bush, c, und has a sluiting-box, y, iu its upper end, so as to prevent all leaking from the wheel-case, around the shaft li. The outer edge of the iop (iy is secured by bolts or screws to the stationary guides G (l, which project upward l'roin the main caso A, and between which the water is admitted to the wheel. The topis raised a little inside, above thc guido. in order to gire free room for the wheel to turn beneath, and not interferewith the projeetinfcr holt-loads or screws onthe top wheel-plate, by which the wheel-buckets are secured to the said plate.

The next feature of my improvement consists in the construction and combined arrangement of the gates E E, mounted in a ring. and connected together, and of the stationary guides G G, also situatedln a ring, the ring of gates having adjustable valve-plates, of peculiar form and arraugeinent,`and the guides, having peculiar positions, with chutes between them, of peculiar form, in relation t0 the wheel L within, substantially as I shall describe.

First, the gates E E are arranged at uniform distances apart, in a ring, their inner surfaces heilig accurately formed and situated in the circumference ol' a single circle, concentric with the wheel L, and the Aguides' G G are similarly arranged, at uniform and corresponding distances apart, their outer surfaces being accuratcl y formed and situated in the circumference of a single circle, concentric with the wheel, and coinciding with the circumference of the circle described by the said inner surfaces of the gates, so that the gat-es fit closely around the guides, but may turn on their center, outside ot' the guides, without impediment. Y

Second, the inner surfaces of the guides G G do not reach quite into the periphery of the wheel, or the outer edges 0f its buckets y p, but leave a narrow annular space between, through which a small quant-ity of water may flow, for the purpose of obviating ii'iction and obstruction between the guides and buckets.

Third, the edges ofthe guides G G, forming the outlines ot' the chutes K K, through which the water is admitted to thc wheel L, on all sides are in planes tangential to the outer periphery of the wheel, so that the water is directed to the buckets in acourse tu produce the best effect, and, whcn the gates are moved to open the chutes to the. water, as shown in iig. 3,

their rear inclined surfaces, 'r t', are in line with the adjacent edges of the guides, so that thc water is di rected in unbent sheets upon the wheel.

Fourth, the front edges of the gates E lil are covered with valve-plates, h h, made ofelastic metal, and thin enough to bend and yield to pressure, their inner edges reachinor inward through the chutes, inst in front of the edges ot' the gates. This part of the plates forms planes tangential to the wheel, or is slightly curved, butlies in the saine general direction7 as shown, si) that they will shut tightly against the rea-r edges of the guides (`r G when the chutes' are closed by the gates, and the chutes will always retain a wedgeshaped form, whether wholly or only partially opened thereby, and will direct the water in straight unbroken sheets to the wheel. The outer ends or tlanges of the valve-plates bend around the outer surfaces ofthe gates, to which they are attached, by set-screws ifiy passing,r through horizontal slots in the plates, for the purpose of adjusting the positions ofthe plates acculrately,'tliat they may close all the chiites simultagenerally from ten to thirty-six, according to the corresponding sizes of wheels.

The gates E Eure mounted between tirol-ing llanges, D D, to which they are fastened. To the upper ange D a cross-bar, H, is secured, and extends; oss the top of the case. 1t has a central opening, which titi-i around the bottom flange ot' the carp or dome B, and turns thereon as a pivot-guide. A segment rack, I, projects from one side otI the cross-bar, and gears into a pinion, J, on a short vertical shaft, lig-which is mounted on the ease-top a, andiii a frame, m, secured upon the said top, orbearings. The shalt cisturned by a hand-wheel or crank, l. By this device all the ring-gates E E are moved simultaneously mitin-ning,r the said hand-wheel.

Another ieature of my improvement consist-s in dividing the ring-gates E E into two or more sections, or in the einploinient ot' two or more rings oi' gates, one over the other, so asto let the water into the wheel, either in dilferent quantities at the top and bottom, or all at the bottom, as may be desired.

This improvement is shown infh'g. 5, which represents two rings or sets of gates, E E and E E', and the manner it'o1iei'atiiig-tlieiin so as to open thelower ringer set ti'ist,'entirely, ei' partially before. the openot' -the second orupper ring of gates commences, and 'the closing of those setaalsowillrbe one in advance of the other', -theone which'qop'ei'is last closing tirst.

. The iiieansof producing. this movement, as repreysented, is by extending th'e shaft 7c of the hand-wheel "l' down, outside o f theqivateieivhecl ease, and placing th'ereon two piuions, l a?, one opposite to the flange D ot' the upper gate E E, and the other opposite to the flange D otthe lower gates E' E. On the upper flange D is a short rack, t, into which the upper pinion gears, andon the lower tlau'ge D is a short rack,

l u, into which thelower pinion gears. These two racks are not apposite to each other, one over the other, but one is alittle to one side of the other, so that the pinion will take first into one, and move the gates as far as desired, before the other pinion takes into its rack. Then there is a. cog or stop,'ii, on the lower edge of the upper riiig,.and a stop, w, on the upper edge, oi" the lower ring, the two being,r so arranged as to have one strike the other, at the pioper time, and thereby bring the rack ot' the other ringinto gear with its pinion at the moment required, and lvice' versa, on the return movement. Similarly, if there are three or more rings or gates, one opens before another, in succession.

Another feature of my invention consists iu dividing the buckets@ p by a horizontal paitit-ion-iilate, y, one in each, as 4shown at the right hand in g. 5, or two, as seen at the left hand in the same Atigure, into two or threecompartments z z, cach corresponding; with the double or ltriple rings of gates above described. By means of' these' compartments only the lower, or two lower rings or sets ot' gates, may be. opened, and

upward reaction, to relieve the weight ot the wheel on its step, as it' the whole wheel received thc water. lJhis is a- .valuable feature for small streams, oi' when the water is low. n v' That I claim as my invention,and desireto secure by Letters Patent, is-

rlhe cover a ot' the watcr-wheel case, constructed with a large central aperture, covered by a divided removable cap or dome, B, substantially as and for the purpose herein speeilicd.

Also, the ring-gates E E, with their adjustable valve-plates l1 7i, the guides G G, and chutes K K, lcoi'istructed, arranged, and combined substantially` as and for the purpose herein set forth. Also, the two or moi'ehsots ofgatcs E E and E' E, one: above the other, to cover the saine chutes K K, in combination with buckets pp, divided into compartments, substantially as and for thc pin-pose herein spccitied.
