UNITED STATES PATENT EEICEo ROBERT STEWART, OF FULTONHAM, NEW YORK.
IMPROVEMENT IN WATER-WHEELS.
Specification forming part of Letters Patent No. A 5,@ 5, dated January 10,1865.
To all whom t may concern Be it known that I, ROBERT STEWART, of Fultonham, in the county of Schoharie and State of New York, have invented a new and Improved Water-VVheel 5 and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being hadv to the accompany ing drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. 1.
Similar letters of reference indicate like parts.
This invention relates to a new and iinproved water-wheel of that class in which the power of the water is obtained both by impact or percussion and reaction.
The invention consists in the peculiar shape of the buckets in connection with their mode of attachment to the wheel, as hereinafter set forth, whereby it is believed that a wheel of economical construction is obtained and one which will give a large percentage of the power ofthe water;
A represents a scroll, in which the wheel B is placed, said scroll gradually diminishing in width from its outer to itsinner end, where an abutment, c, is formed. (See Fig. 2.) The shaft C of the wheel has its lower end, stepped in a bridge-tree, D, below the scroll, and the wheel is composed. of a cylindrical case, b, attached by arms c to the shaft, and having buckets Z attached to its periphery. The buckets d are composed of or have three dit ferent surfaces for the water to act upon. The central surface, e, has avertical position on the case Z1, and has an oblique position relatively therewith, forming an obtuse angle at the side, against which the water acts, as will be seen by referring to Fig. 2. The upper and lower surfaces, ff, of the buckets areinelined from cto the upper and lower ends of the case b,and in a direction toward or facing the current of the water, said surfaces forming the discharge passages or issues g, which gradually contract from their outer t0 their inner ends, as shown in Fig. l.
The buckets d are encompassed at their upper and lower ends by rims or bands L 71, which form outer cases for the discharge passages or issues, the outer ends of the latter being iiush with the upper and lower surfaces of the scroll, as shown in Fig. l.
The water in passing into the scroll first acts by impact against the vertical portions c of the buckets, and is discharged through the passages orissnes g, both at the top and bottom of the wheel, the water exerting a reacting force against the partsf.
The transverse oblique direction of the central parts, e, of the buckets admits of the water passing' uninterruptedly around or through thescroll, and still allows it to act effectively upon or against'the buckets.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Paten t, is-
The buckets (I, having the vertical transverse oblique and inclined surfaces c f f, and attached to the case b, with the bands h h, encompassing the inclined surfaces f f, in connection with the scroll A, all arranged substantially as set forth.
ROBERT STEWART.
