- IMPROVEMENT IN WATER-WHEELS.

. Y? Specification forming part of LettersPatent N o.

.r May Z'o all whom lit may concern Be it known that I, RICHARD M. GADDY, of Nichols, in the county ot' Marion and State ot South Carolina, have invented certain new and useful Improvements in Water- Wheel; and I dohereby declare that the following is a full, clear, andA exact description thereof, which will enable others skilled in the art to vwhich it appertains to make aud-use the same. reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part otl this speeiiication.

The nature of my invention consists in the construction and arrangement of a waterwheel, as will be Hereinafter more fully set forth.

In the annexed drawing, Figure l is a central vertical section on lille a: x, Fig. 2. Fig. 2 is a transverse crosssection on line yy, Fig. l; and Fig. 3 represents a bottom view ot' the wheel.

A represents the vertical shaft on which the wheel is secured, said shaft having its lower bearing in the bridge-tree B, under the curb or casing C, and its upper bearing in a spider or cross-bar within said casing. The casing C may be constructed in any suitable manner, and have any desired number of chutes, a, for admitting the-water into the same above the wheel, and also have suitable gates for letting on and shutting' ott' the water, as required. The wheel D is made in bowl or semi-spherical shape, hollow, and out with a series of spiral Yslots or openings, b b, running from near the upper edge to near-the center of the bot-tom ofthe wheel,'so as to leave, as'it were, a solid top rim, and a solid center disk, with a series of spiral fanshaped pieces, D1, between a-nd connecting said rim and disk. Each of these spiral pieces D1 is curved or beveled inward along one edge, and from the top to the bottom along this edge, on the inside of the wheel, isa spiral tapering flange, D2, as shown, the two spiral parts D1 l 79,6496, dated July "11, 1876; application filed 17, 1876.

and D2 forming the bucket of the wheel. The outer edge ot the bucket as thus formed is also beveled, as shown. The shat't A passes through, and is fastened in, the center ot' this wheel, and on the shaft are tormeda series of spiral flanges, d d, which extend from the bottom of the wheel upward a suitable distance abovel the top ot' the wheel. The relative dimensions ofthe shaft and wheel are such that a space will be lett all around the shait bctween the outer edges oi' its spiral flanges and the inner edges ot' the buckets, as fully shown in the drawing'.

The chutes ce in the ease C being above the wheel D, the waterI passes through the same, and down onto the wheel, acting both on the buckets and on the spiral angesof the sha t. t

rlhe water that strikes the iiangcs d ot' the shai't aids in rotating the wheel, and Athen as p the same water falls down onto the buckets it acts on them, giving still greater impetus to, and accelerating the motion ot', the wheel.

The wheel may be made ot' wood or metal, or of both combined, as desired.

Having thus fully described my invention, what I claim as new, and desire to secure by, Letters Patent, is-

l. A water-wheel made hollowin semi-spherical iorm, and provided with interior buckets, substantially as herein set forth.

2. The water-wheel D, made hollow in semispherical form, with spiral slots b, and spiral interior buckets DL D2, substantially as and for the purposes herein set forth.

l 3. The shaft A, provided with spiral flanges d, in combination with the wheel D, as and for the purposes set forth.

In testimony that I claim the foregoing as my own I aiiix my signature in presence ot' two Witnesses.
