ATTORNEYS JOHN B. HAMILTON, or LOUDON, TENNESSEE.
IMPROVEMENT IN WATER-WHEELS.
Specification forming part of LetterslPatent No. 146,068, dated December 30, 1873.;` application filed` February" s, 1813. y
. fTo all whom it may concern:
Be it known that I, JOHN B. HAMILTON, of Loudon, in the county of Loudon andState of Tennessee, have invented a new and valuable Improvement in Water -Wheels; and I do hereby declare that the following is a full, clear, and exact description of ther construction and operation of the same, reference being hadto the annexed drawings making a part of this specification, and to tl1e" letters and figures of reference marked thereon. I
Figure l of the drawings is a representation of a horizontal section of my water-wheel.
This invention has relation to horizontal center-discharge water-wheels, wherein the water is directed against the buckets by means of scroll-shaped chutes.
The nature of my invention' consists in constructing Athe spurred buckets with beveled or inclined upper edges, in combination with an inclined or beveled surface formed on the lower side of the top rim of the wheel, for a purpose hereinafter explained.
The following is a description of my improvements In the annexed drawings, C C represent two scroll-shaped chutes, forming part of the wheelcase, and serving to conduct wateragainst the buckets B. These two chutes occupy the entire circumference of the wheel, and supply the water uniformly from all directions, so as to nicelybalance the forces acting on the wheel.
The wheel is composed of a horizontal topdisk, D, la horizontal bottom ring, E, and buckets B, secured together as follows: In casting or otherwise forming the buckets, I construct spurs or lugs 'b on their upper and lower edges, which spurs are preferably of tapered or wedge form, and are arranged at or near the ends of the buckets and in therniddle thereof, as shown by Fig. 4.
In casting the disk Dand ring E, I form holes into their surfaces, corresponding in their arrangement to the required position of the` buckets in the wheel, and to the number of spurs b on the buckets.
It will now be seen that when the buckets are all adjusted in their places, and the disk and ring are firmly secured by bolts c, theV buckets will be rigidly held by their spurs.
Should any one or more of the buckets be broken they can be readily removed by loos` l ening the nuts on bolts o, and other buckets adjusted in their places.
It will be seen that the disk D is constructed with a beveled surface, a, Haring upwardly and outwardly, for the purpose of having the spaces between the buckets largest at their entrance, and thus greatly increasing theimpact of the water on the wheel.
My buckets are inade to fltsnugly to this inclined surface a by beveling their upper edges-that isto say, I taper the buckets, as shown in Fig. 2, to correspond to such beveled or inclined surface.
Having described my invention, what I claim as new, and desire to secure by Letters Patent,
The tapered and spurred buckets B, combined with the beveled surface on' the disk I),
as and for the purposes described.
JOHN B. HAMILTON.
