GEORGE E. OORBIN AND JOHN W. PUGH, OF GRAND RAPIDS, MICHIGAN.

IMPROVEM ENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 56,719, dated July 31, 1866.

To all whom t may concern:

Be it known that we, GEORGE E. GORBIN and JOHN W. PUGH, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and Improved Water-Wheel 5 and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section of our invention, taken in the line .r x, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. l; Fig. 3, a side sectional view of the Wheel detached or removed from the scroll.

Similar letters of reference indicate corresponding parts.-

This invention relates to a new and improved water-wheel of that class which are placed on a vertical shaft and one inclosed within a case.

The invention consists in a peculiar shape and position of the buckets of the wheel, together with a wing and chutes or guides for directing the water properly to thebuckets, and in a novel application of the case to the wheel, whereby several advantages are obtained over the ordinary wheels of'the same class in use, as will be hereinafter fully set forth.

A represents a framing, which may be constructed in any proper manner to support the wheel and its concomitant parts. B is the shaft of the wheel, the lower end being stepped in a cross-tree, O, of the framing A, and the upper end working in a bearing, a, on the upper part of the framing. D is the wheel attached to the shaft B, and provided with buckets b, which are of Vcurved form in a vertical direction, as shown clearly in Fig. 3. These buckets are not attached to the wheel in a radial position, but are tangential with a circle, c, concentric with the shaft B of the wheel, and about four times greater in diameter than said shaft. The buckets are encompassed by a rim or band, d.

E represents a case of cylindrical form, and having a tube, F, tted centrally in it, through which the shaft B passes, as shown clearly in Fig. Yl. This case is firmly secured in the framing A in any proper manner; and within said case, just above the wheel D, there are placed a series of chutes, e, which correspond in shape and position with the buckets b of the wheel, with the exception that the former have their vertical curvature in an opposite direction to that of the latter. (See Fig. 3.)

The chutes c are stationary, and directly above these chutes e there is an induction spout or iiume, G, which has a wing, H, extending from its inner end to the tube F. (See Fig. 2.) This wing is designed to give a proper direction to the water in entering the case E.

The lower part of the wheel D, it will be seen, projects below the case E, so as to admit of a free discharge of 'the water.

From the above description it `will be seen that the case E cannot in the least interfere with the wheel-shaft B, as the latter passes through the tube F and is completely isolated from the case; and in the event of the stop of shaft B becoming Worn so that the Wheel will have a little lateral play, the shaft B will not come in contact with any portion of case E.

By having the buckets of the wheel of the shape and arranged as shown in the position relatively with the wheel, the water is made to act with its greatest eEective force against the outer parts of the buckets, where it will have the greatest power, and the water is further allowed to escape freely from the buckets after the force of impact has been imparted to them. This action of the water is aided by the chutes c, which guide or direct the water properly to the buckets, and is also aided by the wing H,

which gives the water a proper direction in.

the case E above the chutes e.

The tube, F, it will be seen, only extends down to a level with the bottom of the chutes.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination of the buckets l) and wheel D, cylinder F, with chutes c and tube F, all constructed as described, and winged spout G, arranged and operating in the manner and for the purpose herein specified.

GEORGE E. OORBIN. JOHN W. PUGH.
