Be it known that I, JAMES REED, of Newville, in Richland county and State of Ohio, have invented certain new and useful Improvements in lVater-lVheels; and I do hereby declare that the following is a true, full, and exact description of the same, reference being had to the accompanying drawings, which are a part of-this specification.

Figure l is a sectional view of a hub of a water wheel, having buckets like those used in my improvements. Fig. 2 is a top or E plan view of a wheel having such buckets. Fig. 3 is a view in perspective of one of my improved water wheels, in connection with a chamber, into which the water that moves the wheel passes. Fig. & is a sectional view of a cross section of one of the buckets of my improved wheel, showing the convexity To remedy the deficiencies I have observed in the water wheels now in use, I have ascertained, from actual experiment, that water wheels to be most efficient, should be conwater when applied. agreeably to its most efficient law, upon a surface of such a character as to receive the greatest efiect from it, when thus applied.

My invention consists in the construction, and application of an eccentrically spiral and convex bucket, to the hub, or shaft of the wheel, saidshaft having a vertical, or nearly vertical position, in order that the water when applied agreeably to its most eflicient law.

The bucket used in my improvement descends spirally, from its upper terminus, in nearly the same degree for about three fifths of its length, whence it descends, spirally, much more rapidly to the point at which the water issues from the wheel. I contemplate using only two such buckets on my improved wheel, and their respective ends fail to meet, on the hub, or shaft of the wheel, by the space of an inch, more or less. I place a band around the periphery of this wheel, of the width of the space, or width on the hub thereof, covered by the buckets. I apply the water to my wheel according to the hydrostatic rule, or principle of its action, by conveying it, through a proper or convenient conduit, into a cham- PATENT FFICE.

the band, or rim of the wheel, and of any convenient height. Said chamber may extend above the point, on it, at which the water is let into it, and the hydrostatic pressure, therefore will be greater or less as the water is high or low in the chamber, or if the chamber be only of a fixed height, the power will be greater or less as the elevation of the water above the chamber, is greater or less in the flume or reservoir from which it is conducted to the chamber.

As the principle of thepower of the pressure of water, when hydrostatically applied is well settled as a scientific fact, any remark upon it will not be needful in this specification. It will be remarked, however, that it has been shown, by experiment, that my wheel, on a trial in comparison with other wheels of the character set forth in my disclaimer was more efficient under equal circumstances.

The letter A, Fig. 1, represents the character, shape, and position, on the shaft, or hub of the wheel, of the bucket in my improved water wheel, which in its downward inclination, is spiral to a certain degree for about threefifths of its length, whence it descends, spirally, more rapidly to its end at which the water flows from the wheel. The ends of the buckets are brought to an edge, or nearly so, and the lower side of the bucket is of a smooth surface, and nearly conforms in shape to the upper side. I have constructed my bucket of this form, for the purpose of securing the power of the hydrostatic pressure upon the whole surface of the bucket; and at the same time have provided by the more rapid descent of the lower part of the bucket, to receive the side pressure of the water against the bucket, in the line of its motion.

The letter B, represents a chamber, drawn in red ink, for the reception of a column of water by the hydrostatic pressure of which my wheel is to be moved, and which may be carried to any convenient height. It is to be of the exterior shape, and diameter of my Wheel, and is to be placed on or over it in such a manner as will permit a free revolution of the wheel, which is represented in black ink, as on its shaft, or spindle, and standing on the block, in red ink, marked D, Fig. 8.

I am aware that water wheels, with buckets spiral and concave and plano spiral have been used before the date of my applicaacter above stated, in combination with a 10 tion; and I therefore disclaim each and all circular chamber for the purpose set forth of them; but and substantially as described.
