WATER-WH EEL.
SPECIFICATION forming part of Letters Patent No. 240,102, dated April 12, 1881.
Application filed September 3, 1880. (No model.)
To all whom it may concern Be it known that I, ISAAC F. DAVIS, a citi zen of the United States, resident at Greensborough, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Water-\Vheels, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification.
My invention has for its objects to provide an improved turbine wheel which shall be simple and cheap in construction and strong, durable, and capable of running at high speed with moderate pressure or a comparatively low head of water. My wheel is an outward-flow wheel, taking its water from the inside and striking the buckets with a direct impulse and discharging it freely, but in such a way that both the weightof the water and the force of its discharge are utilized in driving the wheel. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a partial plan view, a portion of the shaft and its supporting-arms being bisected. Fig. 2 is a vertical sectional view. Fig. 3 is a side elevation; and Fig. 4 is a detail view of one of the buckets.
Referring by letter to the drawings, A designates the stationary rim or annular supporting-plate, which sets in the floor of the penstock. The interior of the supporting-plateA is of the same diameter as the diameter of the wheel B at its largest or upper interior diameter.
The chutes O, which are of semi-crescent shape, are secured to the supporting-plate A and are upon the inside of the wheel, so that the wheel will revolve around and under them.
The supporting-plate A is provided on its under face with two annular downwardly-projecting rings or flanges, l) D, made solid with said plate, and between which the rim of the water-wheel runs. The inner ring or flange,D, prevents the water from running over the top of the wheel, while the outer ring, D, holds it in its track. The chutes 0 curve downwardly and inwardly to a stationary sleeve, E, and form the sides and bottom of a basin, F.
Gates G are pivoted to blocks H upon the bottom of the basin F, and are connected, by pivoted rods I, to a sliding sleeve, J, upon the shaft K.
Arms L, three in number, rise from the supporting-plate A, having a bearing, M, at their junction, in which the upper end of the shaft K revolves. The lower end of the shaft K is stepped on a point, N, secured in a threearmed bed-piece, O, and rods 1? rising from said arms are secured to the supporting-plate by nuts.
The wheel B has its floats or buckets Q, cast with the rim and its hub S, and they are cymbiform and curved, as shown. The openings between them at their lower ends are smaller than the spaces between them at their upper ends, and they are inclined upward from the bottom of the wheel. The hub is an annular disk keyed to the shaft K. The inclination of the buckets upward is at an angle of about forty-five degrees, and this inclination, together with their peculiar form, gives the shape of an ordinary basin.
A lever, T, is pivoted to one of the support in g-arms L, and has a collar, U, which encircles the sliding sleeve J, and is pivoted thereto, so that by elevating or depressing the lever the gates may be opened or closed. The gates are of about the shape of the mouths of the chutes,
and, being pivoted at the bottom, they may be only partially opened when a full head of wateris not needed, and will cause the water to flow against the tops of the buckets, and, owing to the shape of the wheel, the weight of the water will be all utilized as well as the force of the discharge. The lower ends of the buckets hav- 3. In a turbine wheel, the gates G, pivoted to the bottom of the basin F, formed by the chutes (J, in combination with the rods I, sliding-sleeve J, and lever T, pivoted to one of the supporting-arms L, substantially as and for the purposes set forth.
In testimony whereof I affix my signature in presence of two witnesses.
ISAAC F. DAVIS. Witnesses:
