IMPROVEMENT IN WATR-WHEELS.

The S cheule xefen'ed to in theseLettei-s Patent and making part of the same.

To all whom 'it 'may conce'r'n:

Be it known that I, FRANKLIN HoYT, of Montpelier, in the county of VVashington, and State of Vermont, have invented certain new and useful Improvements in Water-Wheels, of 'which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part o'f this specification, and ilu which- Figure 1 represents a Vertical section of my improved water-wheel at the line x x of fig. 2.

Figure 2, a horizontal section of the same, at the line y y of lig. 1. l

Figurc 3,.a view in perspective of the gates, 'and theimechanism by which they are moved, detached, an w Figure 4, a similar' view of the chutes, detached.

The object of my invention is to provide a waterwheel which shall possess the combined advantages of a turbine and a breast-wheel, as well as to afford an improved means of regulating and stopping'the supply of water thereto; to which ends,

My improvements consist,

First, in constructing the buckets of curved form, both vertically and laterally, whereby the entering water acts upon them first by impact, as in ordinary breast, and aterward by gravity, as in turbine Wheels, as hereinafter described. w

Second, in a series of curved gates attached by pivoted arms to a ring which encircles them, and which sfirotated by gearing in such manner as to diminish on' close at pleasure the openings through which the water is admitted to the chutes.

In the accompanying drawings, which showa' convenient airangement of vparts for carrying out the objects of my invcntion, A represents the wheel which rotates in a casing or penstock, B, to which the water is conducted through the head-race B'.

A represents the wl'ieel-shaft, which bears on a step, al, on the frame A2. y

The buckets a of the wheel are curved radially ther'eto, as in turbines' of lordinary construction, andare, likewise, curved vertically for a portion of their length toward their lower ends,l which extend below the bottom plate b of the-casing B, and are surrounded, for this portion of their length, by a band, a, connecting their outer edges, and extending npward from the plane of their lower edges to the upper face of the' bottom plate b of the casing B, 'and formingarun'ningwater joint therewith, as shown in fig. 1.

By this construction, the water is prevented from flying off centrifugally from the buckets afteracting upon them by impact, and is retained until all that is let into the wheelshall have descended the whole length of the bncket in the space between the band a and the hub-cylinder of thewheel, to be discharged at the bottom of the buckets without waste, after pro- The water is directed to the buckets by the curved chutes f f which are united at top by a plate, F, through which the shaft Al passes, and secured at bottom to the casing B, the chutes being inclined toward the wheel, as shown in red lines in fig. 2, to properly di- .rect the currents of waterthereto, i i

Curved gates, D, are placed within the chutes f, 'being secured -at one'end to pivots, d, mounted in hearings in the casing B, and connected at their opposite cnds, by pivoted links, c', to a ring, O, which ing. I

Byirnparting rotary movement to the. ring O, by means of the pinion e, on the Vertical shaft E, gearing 'into teeth,.c, on the inner surface of the ring, the gates D can be moved so as to increase, diminish, or shut off entirely the supply of water to the wheel, according as each gatc is moved from or toward the to he regulated at pleasure.

Having thus fully described my inventi'ou,

Vi-fhat I claim, and desire to secure by Letters Patent, is-- p 1. The wheel A, constrncted substantially as dea, and the band a, in combination 'with the bottom .plate b of the casingB, asand for the pnrpose speci fied.

2; The gates D I), in combination with the chutes f j; pivoted links 'c'.;', and ring O, the whole arranged au'd Operating substantially, as and for the purpose described.

In testimony that- I ciaim the -foregoing a's my invention, I have hereunto set my hand and seal, this 6th day of March, '1869.
