UNITED STATES JOHN HAsELTINE, 0E MELROSE, MAssAcnU'sETTsi `IMPROVEMENTIN `WATER-WHEELS Specification forming part of Letters Patent N o. 14,535,

dated March 25,1856; extended seven years; reissue N0. 6,873, dated January 25, l'fapplicatinn filed December 23, 1875.

To all whom it may concern:

` Be it known that `I, JOHN HAsELTINE, of Melrose, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Water-Wheel, and combined the same with a case or guide sol as to operate in a new manner, which inventions are fully set forth in the following specitieation, reference being had to the accompanying drawings, of which- Figure l is atop view of my wheel in a scroll case or guide, with the cover on, which conducts the water to the entire periphery of the wheel. Fig. 2 is a top view of my wheel in the scroll-case or guide, with the cover removed. Fig. 3 is a bottom view of my wheel in the scroll case or guide. Fig. 4 is a side view of my wheel out of the case, witha section of the hoop removed. Fig. 5 is a vertical sectional View of the wheel4 out of its case, on the line wa'. Fig. 6 is a view in perspective ofthe shaft, with four iioats attached.

My invention consists in making the outer portion of the float, upon which the water acts rst, radial; the next portion, which receives the action of the water, tangential; and the lower portion, upon which the water acts by its head, to incline downward from the shaft or center of the wheel, and from the tangential and in combining the same with a case in a novel manner.

- A A A A are the sides, and B is the bottom, of a scroll, and C is a cover which fits closely on top of these sides, the shaft of the wheel passing through the aperture in it and llng it substantially. These parts A, B, and O constitute a case in which the wheel runs, and by which the wheel is supplied with water. It is made so deep as just to allow the radial and perpendicular portion D of the Goats to turn freely in it, while it gradually diminishes in width to its termination.

A series of iioats projects from the shaftof the wheel at equal intervals` all around it.

The radial portion D of the float may be connccted to the shaft E ofthe wheel by the tangential portion F ofthe oat, and this tangential portion is made perpendicular to or parallel with the shaft, as represented, and stands upon a tangentto a circle drawn with the axis of the shaft for its center.

The inclined portion G of the oat is joined to the lower edge of the tangential portion F, so as to incline downward from the tangential portion to its edge, and from its inmost extremity to its peripher or where it joins the rim or hoop H of the wheel, which rim or hoop surrounds. the extremities of the inclined portions Gr of the floats, and is preferably joined to them.

The shaft E is provided with pivots I I,which may be tted to turn in appropriate boxes fitted for them.

The oats above mentioned may be made of wood, or of wrought or cast iron, or the wheel may be cast whole, as preferred.

The water enters the case, as indicated by the arrows, Fig. 2, and acts on the radial por, tion D of the iioats, and, as it is confined by the case' or guide everywhere except where it enters the wheel, it necessarily turns toward the shaft of the wheel and acts on the tangential portions F of the floats, and, by its head, on the inclined portions Gr of the io'ats,which inclined portions are as nearly as may be concentrically opposite to their discharging-apertures-that is to say, so'that a circle drawn in a horizontal plane about the center of the fwheel, so as to pass through any point of a discharging-aperture, will alsointersect the in-4 clined surface next in front of it, from which the water flows through this aperture-from,

which the water tends to iiow in the direction ofthe periphery of the wheel, the inclined portions being' so arranged that the water has a tendency to flow or run toward the periphery of the wheel as it descends through it.

By the inclination of the floats from the periphery ofthe wheel upward to the interior extremities of the oats a cavity is formed within the wheel surrounded by the iioats, as indicated more particularly in Figs. 3 and 5, and the water discharges in this cavity, and thence downwardly and outwardly, which it could not do were the rear edgesof the inclined portions of the Boats in a plane at right angles with the axis of the shaft, in which case the above-mentioned cavity would not be in the wheel.

It will be apparent that this inclination of the oats from the periphery ofthe wheel upward toward the interior of the wheel makes the length of each of the discharging-orifices greater than the distance horizontally from the shaft to the peripheryof the wheel, which is a new and useful result in this species of wheel.

- What I claim as my invention is- 1. A water-wheel having ioats with radial,

tangential, and inclined portions, constructed and arranged substantially as described.

2. A water-wheel having' oats with the tangential and downwardly-inclined portions so arranged that the discharging-orifices are concentrically opposite the inclined portions,-in a case or guide and rim, all so constructed that the head of water always presses equally on all the floats at once, substantially as de scribed.

3. A watenwheel surrounded by a rim above which the water enters the wheel, having floats the lower portions of which are so inclined downward toward the periphery of the wheel ,that the water shall tend to flow toward the periphery of the Wheel, substantially as described.

4. A water-wheel, `with its guide or case substantially as described, having oats inclined upward from its rim toward their interior extremities, so as to permit lengthening the discharging-,apertures and forming a cavity within the wheel, substantially as described.
