Lette/rs Patent No. 84,047, dated November 17, 1868.

To all whom t may concern:

Be it known that we, J. H. BoDrNrr and T. A. HrLL, of Mount Morris, in the county of Livingston, and State of New York, have invented anervand improved Water- Wheel; and we do hereby declare that the following is a frrll, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of .this specification, in which- Figure 1 is a vertical axial section of wheel and curb.

Figure 2 is a bottom view of the gate.

. In this inventionthe gate is made in a peculiar form, to adapt it to be opened and closed with less power, and a novel device is employed for the purpose of moving it; Iii-addition to this, the curb is so constructed that as the step wears away, the joint between the wheel and the curb still remains water-tight In the drawings, A represents the curb, having tight side walls, arid so constructed that. the water passes vertically to the wheel;` B, the wheel, of the verticaldischarge pattern; C, the shaft;. F, the central cone, surrounding the shaft above the wheel; D, the step; and E E, braces, by which the step and its socket,'sup ports, and adjusting-apparatus are attached to the curb.

The curb is provided with an elongated rim or flange, a, around its lower edge, which encircles the upper part of the wheel B, the joint between them being watertight.

This iiange extends down over' the sides of the wheel so far that if the step D should wea'r away and drop the wheel down a considerable distance, it would not affect its action, inasmuch the flange would still cover its upper edge, and prevent the escape of the water around it.

The curb is covered by a ilat circular plate, provided with suitable apertures around its outer edge, orrtside of the cone F, to admit the proper supply of water through the chutes H H to the wheel.

I is the gate, in the form of an annular plate, lying flat upon the cover of the curb, and encircling the cone F, being provided with a series of openings, 'i i, at suitable distances apart, to open enclose' the chutes H H to any requireddegree, as the gate is rotated in one4 direction or'tlrc other. 4

The openings i lare usually oi' thc same size and dimensions as the solid parts i i', between them.

The solid parts ol' are made concave on their under side, as see'n Aat c c, iig. l, and shown by fig. 2, so that the only parts o f the gate which bear upon the surface of the curb are the rings in n, at its edges, and the bars o o, which connect them.

The gate, thus constructed and operating, is opened and closed by the following apparatus:

A bevel-gear wheel, w, on au upright spindle, S, pro- The Schedule referred to in those Letters Patent and making part of the lame.

vided with a harrd-wheel, s, serves to operate a. horizontal screw-shaft, T. A block, R, screws back and forth along the latter shaft, 'as the hand-wheel above, is turned, and, as it vscrewsback and forth, moves the gatearound by means o'f an arrn,'v, which is hinged or jointed to the gate at one end, and the blockat the other.

This device not only operates withl great power, but

'holds the gate so rm'ly in anyrequired. position, that it cannot be moved,'except from above, by turning the s indie.

pP P represent the frame, attached to the curb, which vsupports the screw-shaft and spindle.

'lhe gate, thus constructed and operated, is one of the most firm and-durable ever invented, while it can bc opened and closed more easilykthan any other heretofore brought into use.

Having thus described our invention, we do not claim a water-wheelr with side-feed and centre-vent, working in connection with flanges upon a curb having side gates and a tight cover, said flanges being for the purpose of directing the entire volume of water to the centre of the wheel; neither do we claim a combination ofhand-wheel, shaft, and worm-screw, for the purpose of working the gate. The flanges a a, upon our curb, are intended to be used only in connection with a wheel having the-top feed, its sides being cylindrical, and the side walls of the curb being watertight; and the arrangement for operating the gate is limited to the particular combination of cog-gear, screw-shaft, and arrn, described and shown.

What we do claim as our invention, and desire to secure by Letters Patent, is-

l. The arrangement ofthe top-feed vertical-discharge wheel B, in connection with the ilangesa a, upon'the lower edge of a curb, which has .the gate at itstop, its side walls being water-tight, substantially as and for the purpose herein set forth.

2. The gate I, when cast with recesses or concaves, c e, on its under surface, substantially as specified.

3. The arrangement of wheel B, gate I, arm c, screwshaft fl, block R, working upon the screw-shaft, and spindle S, operating' the screw-shaft by means of coggearing W, when said parts are constructed to operate in connection with each other in the manner and for the purposes above described.
