WILLIAM SIMS, OF STAYTON, OREGON.

WATER-WHEEL.

. SPECIFICATION forming part of Letters Patent No. 227,065, dated April 2'7, 1880.

Application filed January 20, 1880.

To all whom it may concern:

Be it known that I, WILLIAM SIMs, of Stayton, in the county of Marion and State of Oregon, have invented a new and useful Improvement in Sectional Turbine \Vater-Wheels, of which the following is a specification.

Figure 1 is a plan. view of my improvement. Fig. 2 is a perspective view of two sections of the wheel. Fig. 3 is a sectional elevation taken through the line a m, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish sectional turbine water-wheels so constructed that the sections may be easily put together and will be held firmly in place.

The invention consists in constructing the sections with inner rims having their ends rabbeted, inclined buckets, and outer rims, made thicker than the inner rims, to give the inclined buckets a slight twist, as will be hereinafter fully described. The wheel is formed of ten (more or less) sections, and each section consistsof an inner rim, A, an inclined plate or bucket, B, and an outer rim, 0.

The inner rim, A, is designed to fit into a recess in a wooden shaft, or between flanges upon an iron shaft, and has ribs or tenons D upon the middle part of its inner or concave surface, to fit into grooves or mortises in the shaft. The ends of the sections A are rabbeted upon the alternate sides, and one of the said rabbeted ends projects, as shown in Fig. 2, so that the adjacent ends of the rim-sections A may be halved to each other.

The bucket B is made in the form of an inclined plane, as shown in Figs. 2 and 3. The outer rim, 0, is made in the form of a section of a hoop or band, as shown in Figs. 2 and 3, and is thicker than the inner rim, A, as shown in Fig. 3. The inner or concaved edge of the inclined plane or bucket B extends from the upper side of the convex edge of the inner rim, A, to the lower side of the said edge. The outer or convexed edge of the bucket B extends from the upper edge of the outer rim, 0, to its lower edge, as shown in Fig. 2. The greater thickness of the outer rim, 0, gives a twist or spiral shape to the bucket B, which tends to equalize the force of the water during the action of the wheel.

Each section A B O is castin one piece, and the sections are bound together by a tire placed upon the outer rims, O, as indicatedin dotted lines in Fig. 1.

The wheel may be made with any desired number of sections. The section shown in the drawings is designed for a ten-section wheel.

By varying the number of sections and the relative thickness of the rims A O the pitch or inclination of the bucket B will be varied as the desired power of the wheel and the fall of the water may require. With this construction the wheels can be made at less cost than wheels constructed in the usual way, and any damage or breakage can be more easily and cheaply repaired.

In the case of small wheels with a thin rim the ends of the adjacent sections may be made square, and need not be halved to each other, as that construction would make them too weak.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A turbine water-wheel made in sections, substantially as herein shown and described, each section consisting of an inner rim, A, an inclined bucket, B, and an outer rim, 0, as set forth.

2. In sectional turbine water-wheels, the section A B O, constructed substantially as herein shown and described, consisting of an inner rim, A, having its ends rabbeted, an inclined bucket, B, and an outer rim, 0, made thicker than the inner rim, A, as set forth.

YVILLIAM SIMS.
