lMPROVMENT IN WATER-WHEELS.4v

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Beit known that I DAVID O. HOLMAN, of Adams, in the county of Jefferson and State of New York, have invented a new and valuable Improvement in `Water-Viheels; and I do hereby declare that the following is a full, clear, and exactdescription of thc construction and operation ofthe same, reference bcing had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.`

Figure 1 of the drawing isI a representation of my water-wheel in horizontal section Figure 2 is a side elevation; and

Figure 3 is a plan view .of the same.

-Iiigure 4.- is a perspective view of the wheel itself,

.and

Figure 5 is a perspective view of one of the gates.

My invention relates to turbines; and

It consists iu the novel construction and arrangement of buckets, casing-gates, and method of operating the same.

The wheel is composed of a ring or cylinder, A, of the same height as the buckets B B, and is, ou its inner side, provided with arm C C, meeting in a ceutral sleeve, D, within which the shaft or spindle E is secured by any suitable means.

B B represent the buckets, so formed'that the inner and outer sides are bounded by cylindrical snrfaces, the axes of 4the cylinders upon which they are constructed being oblique to each other.

The right line of the center of the inside of each bucket coincides with the prolongation of the diameter of the wheel at this point.

The formation of the bucket is illustrated by diagram on sheet 3 of the drawing.

The cylinder-A is perforated with two holes foreach bucket, and the bucket is secured to the cylinder by means of screw-bolts rigidly attached to or formed ou the bucket itself, and passing through said holes, and fastened by nuts from the inside ofthe cylinder A.

The ends of each bucket are flush with the edges of the cylinder A, and somewhat inclined to the direction of the radius, slanting outward and away from the wall of the succeeding bucket.

The curved outer edges of the buckets are designed to fit the cylinder of the-casingneatly.

By the construction of the buckets, and their position with respect to each orher and the cylinder A, it is designed to utilize all the direct force of the water admitted to the wheel, as well as its reacting power', in a superior manner, the tendency of the water being to the outer edge of the bucket er toward the end of the lever-arm.

This wheel is placed in a casing, G, the spindle or shaft E having suitable bearings at its lower end, and where it passes through the top of the casing.

This casing isprovided with a suitable number of chutes or guides HH, which are slightly curved inward, as shown at iig. 1, to guide the water into the wheel.

Above and below the chutes /H H are projecting ilanches a c around the casing, having sueient width to be exactly evenwith the outer ends ofthe chutes. In these iianches are formed semicircularrecesses, ni., each recess com mencing at the outer edge of a chute, and curving inward to the inner edge of the adjoining chute, and then ont again, to complete the semicircle.` The-se recesses are covered on the upper side of the upper tianch and ou thc lower side of the loweriianch by the plates b b, secured by bolts, and extending in scmicircular form beyond the anches.

The plates b are provided with slots c, for the fastening bolts to pass through.

In this manner they are made adjustable, and their position can be changed to correspond with the wear of the gate or the edges of the chutes against which it closes.

In the plates b b, and in the centeis of the circles formed by the outer edge ofthe plates, and the semicircular recesses m, are the bearings of thc adjustable rotating gates I. l

Each gate consists of a horizontally-curved plate. whose outer surface is a portion of a true cylinder, and whose inner surface is correspondingly concave or hollcwed out, this plate being connected with the journals e of the gate by sector-shaped lugs or earsd l projecting from the. concave side.

When the gate is shut it closes the outer opening of the. water-way or space between the outer end of one chute and the inner end of the next. In this position its convex side is turned toward the wheel.

XVhen open, the gates form a daring continuation of the water-way',` their concavities serving to guide the water to the chutes. that the action of the head of water canhave no eiect upon it, as regards changing its position. In what` ever position the gate is placed it will remain, and there is, therefore, no necessity of a locking device.

The gates I I are operated simultaneously by the following means To each of the upper journals e is iirmly keyed au arm, f, which, by a rod, h, is connected with a ring, k, placed around the upper part ofthe easing G at the base of the t'op L. This ring is on one side provided with a rack, through which it is operated by means of a pinion on the upright shaft J. By tux-:F

The forni of the gate is such other, in combination-with the cylindrical body A,

having the perforations s, substantially as specified.

2. The cylinder-shaped concavoconvex gate I, .hav`

ing-its bearings in the'projecting ears .upon the axial line of the cylinder of formation, substantially as spec-rv fied. 3. In combination, the cylinder-shaped rotating gates I I, 'and the adjustable slotted bearingfplates vb,. sub

stantially as specified.

' 4. The casing G, having the centrallydepressed top lL, supporting cylinder It, and flanches a', provided with the semicircular recesses mf, substantially as specified.

5. In combination with the gates I, ears d, and pivots-e, the armsf, rods'h, ring k, and arack and pinion mechanism for operating the same, substantially as specified.

6. The combination of the wheel A B, casing G, cylinder-shaped rotating gates I, and the ring k, with the mechanism for regulating the adjustment of the gates, as specified.

In testimony 'that I claim the above, I have hereunto subscribed my name in the presence of two wit- DAVID C. HOLMAN.
