Description
tirant tata pero effet JOHN H. STAPLES, OF WELLS, MAINE, ASSIGNOR OF ONE-HALF HIS RIGHT TO JOHN H. FERGUSON AND SAMUEL CLARK, AND ONE-HALF TOl SAMUEL CLARK, OF
SAME PLACE.
Leners Patent No. 113,592, dated April 11, 1871.
v iMPROVEMENT IN WATER-WHEELS.
The Schedule referred to in' these Lettera Patent and making part of the same.
To all whom 'it may concern Be it known that I, Joan H. STAPLES, of Wells, in the county of York and State of Maine, have iuvented a new and useful Improveinent in Water- Wheels; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Fgure 1 represents a horizontal section of my improved water-wheel.
' Figure 2 is a detail side view of the same,
Figure 3 is a detail vertical sectionv of one bucket of the same, z x, iig. 2, being the section line.
Similar letters of reference indicate 'corresponding parts.
This invention relates t-o a new manner of constructing the buckets and top plates of water-wheels for the purpose ofpreventing loss of power by an nnprolitable presentationrof surfaces to the moving water.
My invention consists in making the inner surfaces ofthe buckets sloping concavously toward and against the core of the wheel, and in the same manner providing a gradual descent toward the said core or center 'of the projectingl top plate of the wheel.
`The outer face of each bucket and the top surface of the wheel remain straight, as heretofore.
Ain the drawing represents the core or center of the; water-wheel B is the shaft of the same;
O is the upperplate or ange; and
D D are the buckets ofthe same. All these parts are of suitable size, shape, material, and construction.
The buckets are o n the inner faces-that is to say, on the faces which are struck by the water-rounded against the center, forming the concave planes a a, Shown in g. l.` Each lof these concave planes or inner faces tapers almost to a point at the lower end of each bucket, so as not to crowd the contracted, be-
causehorizontally placed, lower spaces between the' buckets.
The water striking the-concave planes a will always reach the same in an inversely radial direction, and can consequently not be thrown back against another bucket or part of the wheel, as only water space is opposite each concave plane.
The back of each bucket is not rounded in conside, also provided with a curvd concave plate, b,
which produces a gradual concave plane, extending from the edge of the plate O to the center. or core of.,
the wheel. 'lhis concave slope serves to close a space which would otherwise also be a useless retainer of water, causing consequent loss of power.
The concave planes c b may be .produced by plates attached to the several buckets or parts of the wheel, as indicated in the drawing; or they may be cast solid or otherwise into their respective places, as may be found to be most economical or preferable.
Having' thus described my invention.
I claim as new and desire to secure by Letters Patent- The straight back c of the buckets, and the inwardly concaved plates b of the top plate C, combined as described, with concave faces a, for the purpose specified. l
JOHN H. STAPLES.
