ROYAL N. DAVIDSOI OF VVEAVERVILLE, CALIFORNIA.
WATER-WH EEL.
SPECIFICATION forming part of Letters Patent No. 253,267, dated February 7, 1882.
Application filed September 2, 1881.
To all whom it may concern Be it known that 1, ROYAL N. DAVIDSON, of Weaverville, county of Trinity, State of California. have invented an Improved ater- Wheel; and I hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to that class of waterwheels which is operated by the forcible discharge of a stream of water upon the buckets or flanges in the rim of the wheel, and are commonly known as turbine water-wheels.
It consists in certain details ofconstructiomas hereinafter described and specifically claimed.
Referring to'the accompanying drawings, Figures 1 and 2 are perspective views of my wheel. Fig. 3 is a vertical section.
Let A represent one side of a wheel having a central axis, B, about which it revolves. The side A is convexcd to its center in conical form. On the front side of A are the flanges or buckets C. These are hollowed or dished out at the periphery of the wheel, and are curved inward toward the center, gradually tapering, as shown. Their inner ends are therefore much narrower than their outer ends, the buckets being made to conform on one side to the convexity of the side A, and on the other side being made straight. Upon their outer or straight sides is secured a rim, D, forming the other side of the wheel. This rim has an opening in the center, so that it really amounts to a ring or band inclosing the outer or dish-shaped ends of the buckets, while leaving the inner ends exposed for the discharge of the water. The apex of the side A is about in the same plane with the rim D, so that the water-spaces formed by the buckets are contracted toward the center both in width and depth.
The wheel isintended to be properlymounted, either vertically or horizontally, and the stream of water directed upon each successive flange or bucket at a point in said bucket near its outer end. The force of the stream revolves (No model.)
the wheel. When the stream first strikes the bucket its velocity is much greater than that ference toward the center, at which point the velocity of the wheel is less than at the circumference, and the diminished velocity of the stream will not therefore act as a drag upon the revolution. Because of the curvature of the buckets a further force is generated by conducting the water to the center.
It will be seen that this is a central-discharge wheel. The force of the stream is directed against the buckets and against the conical side of the wheel. After expending its force it isconductcd toward the center, and because of the conical side A is discharged out of line with the power stream, and thus does not interfere with it, nor does the contents of one bucket interfere with another.
Having thus described my invention," what I claim as new, and desire to secure by Letters Patent, is
A water-wheel consisting of the convex or conical side A, having a central axis, B, the tapering buckets or flanges O, secured upon the convex side and curved and tapering toward the center of the side A, and the rim or side D, with its open center, substantially as and for the purpose herein described.
In witness whereof I have hereunto set my hand.
R. N. DAVIDSON.
