M. DECAMP, OF SOUTH B END, INDIANA.

IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent N0. 40,612, dated November 17,` 1863.

To all whom it may concern Be it known that I, M. DEGAMP, of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and Improved Water-Wheel; and I do vhereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whichl Figure 1 is a vertical central section of my invention, taken in the line a; x, Fig. 2; Fig. 2, a plan or top \iew of my invention.

Similar letters of referenceindicate corre sponding parts in the two tlg-tires.

This invention relates to an improvement in horizontal water-wheels; and it consists in the employment or nse'of a removable funnelshaped ring fitted in the lower part ofthe penstock, and directly over the wheel, as hereinafter fully described, whereby the Wheel may,

.when necessary1 for repairs and other purposes,

be very readily raised from the penstock without removing the decking or planking.

The invention further consists in the employment or use of a ring placed at the bottom ofthe wheel, which is open and arranged in such a manner that the water, when the. wheel is in operation, will not be supported by the. latter, and consequently much friction avoided on the step of the wheel-shaft- To enable those skilled in the art to make, use, and construct my invenlion, I will proceed to describe it.

A represents a quadrilateral penstock provided at its lower part with a decking` or planking, B, within or below which the wheel 0 is placed. This wheel (l is formed of two rims, a a, between which the buckets l) are placed, said rims being connected to the shaft D by means of arms c. The wheelhas an open bottom, and the lower end of the shaft D is stepped in a circular bed-piece, d, on the bottom ofthe tail-racee. (See Fig. I.) On this bed-piece d there is placed loosely a ring, E, of angle form in its transvers section, and the upper edge of this ring lits within a iiange,f, at the bottom of the lower rim a of the wheel, as shown clearly in Fig. l. This ring E prevents the escape of water underneath the wheel.

F is a ring of conical form, the upper edge of which is provided with a horizontal flange, g, which rests on the edge of the circularopening h in the decking or planking B, said Y opening being a trifle larger in diameter than the wheel. The lower edge of the ring F is provided with a pendent flange, t', which tits within the upper rim a of the wheel.

The two rings E F may be of cast metal, and the wheel C may also be of the same material.

From the above description it will be seen that the water, as it passes through the wheel in the direction indicated by the arrows, cannot rest upon the wheel, as the latter is not provided with any bottom. The water will rest or act upon the bed-piece d, and escape through the bucketsl b, the ring E preventing it from passing underneaththe lower rim a. Hence the step of the shaft D is relieved from the pressure caused in ordinary wheels by the latter, supporting the water as it passes through them.

At any time when it is necessary to raise the wheel for alterations and repairs all that is required is simply to elevate the ring F, and the wheel can be elevated at once through the openings h. By this means the trouble of taking up the planking or decking B is obviated.

I would remark that the flange z' of the ring F and the upper edge of the` ring E fit snugly within the rims a a ofthe wheel C, so as to avoid any material leakage ofvwater.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The ring E, placed on the bed-piece d, in which the shaft Dis stepped and tted in the lower rim a of the wheel C, substantially as and for the purpose specified.

2. The conical or funnel-shaped ring F, fitted in the circular opening h in the decking or planking B, and Within the upper rim a. of the wheel, substantially as and for the purpose set forth. M. DEGAMP.
