PATENT OFFICE.

. GEORGE W. CONVERSE, OF SPOKANE FALLS, W'ASHINGTON TERRTTORYP WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 281,459, dated July 1'7, 1883. Application filed SeptemberIE), 1882. (ModeL) I H To all whom it may concern:

Be it known that I, G. W. CoNvERsE, of Spokane Falls, in the county of Spokane and Territory of Washington, have invented a new IO ject obliquely against the sides of the bucket,

on which it acts both by its impact and its weight, escaping from the bottom of the wheel in an annular stream; and to this end the in vention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor-- responding parts in all the figures.

Figure 1 is a plan view of my improved water-wheel with part of the chute-section and also part of the gate broken out. Fig. 2 is a transverse sectional elevation of the same, and Fig. 3 is a section of Fig. 1 on the line 00 0c.

The shaft to is set upright in any suitable step, b, and is provided with a hub, c, to fill the central space for a suitable distance aroundsaid shaft, to prevent said space from being filled with dead-water, or that which wouldbe practically inoperative, so far as driving-power is concerned, because of being so near'the cen ter. The buckets d are attached to this hub radially, said buckets being made wider than the height of the hub, and extending above it to the height of the groove 0 in the fixed center 8 of the case, said extensionbeing'nearly. vertical. From the center of the buckets downward said buckets curve backward, as seen clearly at g in-Fig. 3, so that the weight of the water acts on them after the impact has been expended-on the side of the upperparts, against which it is projected by the oblique chutes h, arranged in an annulus over the buckets. Between the buckets and the chutes I arrange an annular gate, i, fitting in the groove 6. of the central hub, s, and in a groove, j, in the rim is of the chute-case, and having openings Z, which coincide with the chutes when the gate is op e11, and which rest under the partitions m, between the chutes, when the gate is closed, said gate being connected by arms a withthe seg-' ment 0, with which the gate opening and closing shaft 1) is geared. Below the wheel is a bottom, q, attached to the lower edge of curb t, and having chutes u for the escape of the wa ter after acting on the buckets, said chutes being coincident with the-chutes h above, through which the water enters the wheel, and equal in number to them. These chutes u are inclined in the same directionas the chutes h, and they cause the current to set more powerfully in the direction in which the wheel turns, by retarding the discharge of the water, and thereby opposing the tendency of the buckets to set it backward, than it does without them, thus increasing the efficiency of the wheel. I make a packing-box, w, around the shaft 011 thehub s, and cover it with a cap, 3/, to prevent the escape of any water along the shaft. The bot tom q enables the wheel to be set lower down in the backwater than other wheels, without detriment thereby, because the plate q being closed except at the chutes a, through which the inflowing water to the wheel escapes, and said openings being only of the requisite size for the escape of said inflowing water, the backwater has no inlet to the wheel to create back action.

Having thus described my invention, what I claim as new, and desireto secure by Letters Patent, is. I

1. The combination, with the buckets d and the chutes h, of the bottom q, having dischargepassages to, inclined in the same direction as the chutes h, substantially as and for the purpose set forth. 7

2. The combination, with the radial buckets d, vertical, or nearly so, in the upper half, and having the rearward curve 9, and the chutes h, of the bottom q, having discharge-passages u, inclined in the same direction as the chutes h, substantially as and for the purpose set forth.

3. The combination, with the shaft to, provided with the hub c, the curved buckets d g, secured radially to said hub, and the chutes h, of the gate 1', provided with openings Z, and the bottom q, provided with discharge-openings a, substantially as and forthe purpose set forth.

4. The combination of chutes h m, gate 13, buckets d, and the bottom q, substantially as described. 1
