IMPROVEMENT IN WATER-WHEELS.

'The Schedule referred to in the Letten-Patent md making part of the um..

following isa full, clear, and exact description thereof,

reference being had'to the accompanying drawing .ofthe-same which makes part ofthis speciticatiou, nnd'in whichj Figure 1 represents a topview of a water-wheel embracing my improvements;

Figure 2 represents a side elevation of the same;

I "igure 3 represents a vertical section;

Figure 4 represents a horizont-al section of one of the buckets;

' Figure reprcs'cnts a portion of the under side' ofthe upper rim, showing the recesses and'shoulders for the buckets;

f Figure 6 represents a top view of a portion of the upper rim and base plate of the wheel, showing the recesses in the base-plate into which the buckets are secured; and y Figure 7 represents an inverted view of the feeder.

AIn the accompanying drawing thewhecl consists of a central base-plate, A, and an upper annular rim, B, cast in separate pieces, between and to which the buckets C are bolted. l.

The base-plate A isa hollow cone, having a hub, D, projecting from its under side within which a square opening is formed, tapering from the bottom to the top of thecoue toireceiv e the correspondingly-shaped end E of a'vertcal supporting-shalt, F, and thus form a self-locking suspending seat for the Wheel, the weight of the latter tending constantly 'to render its connection with the shaft firm without any fastening, -as it cannot descend below thc wedge-shaped endthereof.

The upper annular rim B is ot' greater diameter than the base-plateand has the same inclination, and the buckets G are therefore secured between* themso as to incline upward and outward and expose their inner concave sides to the directaction of the water within the annular rim.

`lThe buckets C are arranged in curved lines upon the sides of the cone A, so that the spaces a between their inner ends shall he greater than their outlets.

Their inner concave faces, b, have a regular curve with a radius about equal to the circle which 'bounds their lower ends,'while their outer sides, c, havean oval shape, soas to bulge outwardat its back for several purposes, viz, to diminish the discharge-opening d at the back ot' each bucket, and to terminate their ends in sharp edges, as shown in figs. 4 andt6, to facilitate the entrance and discharge of thc water from the buckets.

The buckets are cast separate and secured between the cone A and `the annular rim B in the following manner.:

Ihe cone. is cast with a series of curved recesses or grooves, c, corresponding in form to the cross-section of the buckets, into which their lower ends are -tted so as to lock and hold them in place, as shown in fig. 6; and the under side of the annular rim B is cast with a series ofshoulders, j, against which the upper oval sides c of the buckets are placed, and in these' positions they are locked by screw-bolts g passing through the annular rim, the thickest part of the buckets, and lthe cone A, to tho under side of which they are secured by screw-nuts h.,`as shown in figs. 3, 5, and (i.

The wheel thus constructed issurmounted by a conical feeder, G, supported by a flange, 1'-, upon the door -of the flume.

The feeding-openings H are tangentto ahub, I, and the arms J, between 'which tbeyare made, are inclinedbn theiruuder sides toward the inner end of each bucket, as seen in tig. 7, for-the purpose of imparting to'vthe water a whirling motion within the fiume, and causing it to impinge, bythe -combined action of the tangent arms J andthe inclination of their under sides, upon the wheel in the direction of its motion, and thus gain-.greater power of the water' and steadiness of motion of the wheel than if thewater were'directed through radial openings vertically. Moreover, the 'whirling motionof the water in the flume produced by thetangeut feeders, increases its velocity, and, consequently, the force of its passage through the openings, and this arrangement bas been found'to possess advantages which the radial feeders cannotproducc.

A frustum ot' a cone, K,'is securedin any suitable manner upon the upper side of conical base A, thc upper end of which tits into a collar or sleeve-Jv, in the hub I of thc feeder, for the purpose of forming a guard to prevent the water from entering round the shaft and to deect it outward' against thc buckets; the insulation of the shaft is therefore effected by the Isame device which imparts an interior centrifugal action of the wa'ter against the buckets.

The feeder is provided on itsunder side at.the eircnmference of the feeding-openings H, with an annular rim, l, which encircles a rlm, m, on the annular cap plate Bof the buckcts,f.or the purpose of iuclosing the connection of th wheel with the feeder, andprevent the waste of wa cr bythe wearing down ofthe step of the driving-shaft..

The bridge-tree consists of aframc of four arms,M, bolted*l to the rim or angc i of `thc feeder, and its bearing-point, N, is stepped in the lower angular cud of the driving-shaft.

A conical register is arranged upon the feeder, having tangential openings and arms O, corresponding to those of the feeder, foi` the4 purpose of regulating the quantity ofwater to the' wheel and cutting it off when desired.

The upper sides of these arms O are rounded so as to direct the water into the openings between them in the direction of the motion of the wheel', and thus forni, in connection with the feeding-openings H, oblique tangential chutes directly above the buckets of the wheel. n

It is provided with a cogged segment, n, on its circumference, into which a pinion, p, matches, by which the register is opened and closed,'.as desired.

The pinion is mounted `in bearings in a frame slcured upon the flange i, of the feeder, and the lrange lofmotion of the register is limited by the stopsq, tig.

1, against which the ends of the segment strike.

' By being arranged in tangents to the hub of theregister, the arms O also prevent more effectually the entrance of chunks of ice or drift-wood into the wheel. .The driving-shaft passes through the feeder, and its .upper bearing is formed ina box, P, supported upon a flanged sleeve, Q, which-rests upon the hub I of the feeder, to which the box and the sleeve are secured by screw-bolts, r, passing through their flanges, and clamped securely by screw-nuts on top of the box, by which they may be tightened, and thus obtain a bearing-box secured directly upon the hub of the feeder, so that the shaft passes through the latter and the inclosing-sleeve without touching them.

The object of the double bucket is to close the ontlet-openings d, and bring the bearing of each bucket vdirectly before the water.

l "The feeder conducts the water without any breakage so asto bring its full force directly upon .the buckets,

`thus avoiding friction against the inner and outer rims, and holding it in a body for action.'

Having described my invention,

I claim--` 1. The buckets Qforinng the outline of the wheel in `the forni of a frustum of a cone inverted, said buckets being secured to the base-plate A and annular rim B by means of the recessed seats e and tbe curved, shoulders j; inthe manner described.

2. The inclined buckets, having their outer sides of curves of a radins about halt` that of the inner sides, and arranged so that the sides having the least radius will form, with its contiguous bucket,'enlarged open-- ings at their receiving-ends and narrow outlets, in the manner and for the purpose described.A

3. The hub 'D of the cone A, made with anangular tapering` seat, and the end of the driving-.shaft F of corresponding shape, for the purpose of suspending the wheel upon a self-locking and snpportin g seat without fastening, as herein shown and described.

4. The arrangement of Athe cone K so as to form a continuation of the bascplate A, and he inclosed oy the hub I of the feeder, to produce a centrifugal actionof the water upon the buckets and to insulate the vertical shaft from the water, as described.

5.' The feeding-openings H, arranged tangent to the hub I of the feeder, in the'lnauner and for the purpose described.

6. The register, having tangent openings, in combination with the tangent openings ofthe feeder, in the manner and for the purpose described.

7. The arms of the tangent openings and the arms ofthe feeder, inclined in the saine direction on one of their sides only, so as to direct the water into the wheel and upon the buckets, in the manner described.

8. The buckets O, arranged upon4 a conical'baseplate A, substantially as described, with a feeder constructed with tangent openings arranged within the diameter ofthe upper ends of said buckets, as described.

9. The combination and arrangement of the conical base-plate A, the annular rim B, buckets O, the angular suspending and locking-seat E `of the wheel, the frustnm of a cone, K, the feeder and register, with their tangent openings, the several' parts being constructed, arranged, and operating in the manner herein described.

In testimony whereof I have hereunto signed my name.

RALPH STINSON.
