The invention ,,.hich tl: accompanying illustration depicts, and thc following description elucidates, enables the wheel to be raised and lowered as circumstances may require,_ and the water can be directed into the buckets, at any point of the wheel within the range of its adjustment. The buckets are also peculiarly constructed, so as to obtain a large percentage of power, and the whole wheel is simple and economical. Fig. 1 is a perspective view of the wheel, Fig. 2 is a detached perspecth'e view of a bucket, and Fig. 3 is a section of the same. A represents a circular cast-iron plate, whicli is fitted loosely on a vertical shaft, B, which has a square base, so that the wheel and shaft will rotate together, and the plate be allowed to rise and fall on the shaft. On the lower part of B an inverted conical hub is formed, and through the plate, A, four screws, b, pass vertically, the lower ends of the screws resting on the conical hub. The shaft, B, is stepped into a crossbar on the frame, c, and the upper end has its bearing in a crossbar, d. The upper surface of A has radial grooves in it to receive the arms, e, and they project far enough from the periphery of A to hold the buckets, C. These buckets are of cast-iron, and are of pecUliar form, which is better seen in Figs. 2 and 3. The buckets are formed each of two parts, one part receiving the percussive force of the water, and the other part receives the force from the gravity as it leaves the bucket. The upper part, /, of the buckets are formed of a top piece, g, a back, , and side, i, and a bottom-piece, j ; the top piece, g, and side, i, project from the back, h, so as to form the angles with it, and the bottom piece, j, only extends about half-way across the bucket, a space, k, being allowed, which space forms the orifice of the lower part, l, of the bucket. The lower parts, l, are of scoop form, the bottoms being inclined at about an angle of 45. The outer edge of the back, h, of each bucket has an eye, m, through which the arm, e, passes, and the front edge of the side, i, is notched to receive the arm of the bucket immediately before it. Each bucket, therefore, serves as a bearing tor the arm immediately before it, and each bucket is bolted to its arm by bolts, a. The plate, A, and buckets, C, are covered by a plate. D represents the sluice through which the water ! passes to the wheel, and E is a cylindrical I case in which the wheel is fitted. The sluice, ', is made to communicate with the case, E, S by means of an adjustable mouth, F P, which can be raised up and down by lever, t, and link, ,. G is a sluice gate that regulates the quantity of water. The operation is as follows :The wheel may be raised or lowered within its case, E, by the adjusting of the screws, b, and the water is directed properly into the buckets, C, at whatever height the wheel may be placed by adjusting the mouth, F, by moving the lever. t. The wheel, therefore, may be adjusted according to the height of the water, so that an uniform fall may be obtained. The water first acts against the upper parts,/, of the buckets, by impact and in passing down into the lower parts, I, of the buckets, and out from them a force is obtained by the weight or gravity of the water, and owing to the form of the buckets, as shown, the water is allowed to pass very directly through the buckets, so that there is but little power lost by friction. The buckets by being attached by arms to the center plate, arranged as shown, it renders the construction of the whole extremely simple, and susceptible of being readily repaired in case of a bucket being broken. It is the invention of John Custer, of Find-lay, Ohio, from whom any further information Oan be obtained. A patent was granted May 5, 1858.
