JESSE S. TEED, OF MORAVIA, ASSIGNOR OF ONE-HALF TO \VILLIAM A. KIRBY, OF AUBURN, NEW YORKI WATER-:WHEEL.

SPECIFICATION forming part'of Letters Patent No. 361,556, dated April 19, 1887.

Application filed April 8, 1886. Serial No.198,278. (No model.)

To aZZ whom it may concern:

Beit known that I, J ESSE S. TEED, a citizen of the United States, residing at Moravia, in the county of Cayuga and State of New York, have invented certain new and useful Improve ments in \Vater-Vheels; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the construction of water-wheels, the nature of which will be hereinafter fully explained, and pointed out in the claim.

In the drawings, Figure l is a perspective of the casing employed by me for my improvements. It is partially broken away to show the periphery of the center wheel and the buckets fixed thereon. Fig. 2 is a side elevation of the casing having the cap removed, so as to show the opening in the case, the rollerbearings, and the end of the shaft. Fig. 3 is a vertical central cross-section of the case and wheel, showing a modified form of bucket on a reduced scale. Fig. 4 is a side elevation-of the wheel, one-half of the casing being removed. Fig. 5 is a 1 perspective view of a bucket on an enlarged scale.

The casing is composed of the two end plates or halves, A A, snugly jointed and bolted together. These halves are provided with central openings, A through which the shaft B.

passes, and their outer portions, A A are expanded and made concave or approximately semicircular, as shown, so that when brought together they form an approximately-cylindrical passage, A in which the buckets, hereinafter described, travel in the operation of the wheel. The casing thus made is narrow in its central portions, in which the body of the wheel works. Each end plate has lugs A cast or otherwise provided on the outer face, and arranged so as to provide radial channels or recesses A, for the reception of the blocks 0 O O, which carry anti-friction rollers B which support the shaft B. The casing has an exit-port, A and one or more inlet-ports, A

The inlet port or ports will be explained more particularly hereinafter in their relation to the buckets.

The blocks 0 C may be bolted rigidly in place, but are preferably adjustable, like the block (3, which has a slot, 0 in its shank and is adjusted by a set-screw, O, threaded into the removable caps D. In the revolution of the water-wheel water will be sprayed or thrown through the openings A onto therollers or other bearings B, and will keep the latter perfectly lubricated, so that no other means for lubricating need be provided. The water thus sprayed onto the bearings finds its way back into the case through a small opening, E, near the inner periphery of the caps D. Instead of the roller-bearings B fixed bearing-blocks may be substituted, as shown by dotted lines in Fig. 2; but the rollers are preferred, as the friction and wear are less.

The cap D is of suitable size to provide space for the bearing-blocks O C. It is made so that it can be bolted to the casing, as shown, and is provided with an opening to permit the end of the shaft B to pass through, the latter being packed therein to preventthe exit of water or ingress of air. On the outer end of the shaft a band-pulley, B, or other suitable device may be secured. The set-screw O. is threaded on the cap, as shown. Only one cap D and one set of anti-friction rollers or bearings are shown in the drawings. It will be'understood that corresponding cap and rollers are arranged on the opposite side of the case.

The wheel F is a thin plate or wheel with hub and rim of suitable material, which is keyed to the shaft B about midway between the parallel sides of the plates A A. Its periphery extends about flush with the point where the side plates begin to expand to form the cylindrical portion A To the periphery of the wheel the buckets G are secured. Each bucket G is provided with a shank, GK, which fits into a mortise, G in the side of the wheel F, to which it is securely bolted. The closed end of the bucket is approximately semispherical, so that the water or power medium impinging thereon will be deflected outward on all sides in a sheet or spray. The bottoms G* and tops G of the buckets are oppositely inclined or flared to permit the escape of the spray without causing any lost power or re;

tarding of the motive power. bottoms may be set at any angle to each other and to the radii of the wheel; but the construct1on shown, and more particularly hereinafter referred to, is preferred, and in practice is found to give the best results.

In cross-section thebucket may have the sides 1n planes parallel with the plane of the wheel, or said sides may be expanded and conformed somewhat to the passage A*, as shown in Fig. 3. The principal feature to which I call special attention is that of the bucket in its longitudinal section, whereby the force of the jet of water is always received on the rounded or inner closed end thereof. By reference to the drawlngs it'will be seen that the tops G and bottoms G are so arranged that each stands approximately at a tangent to the periphery of the wheel. This relative position is not so absolutely necessary for the bottom as for the top. The bottom may be made to deflect from the tangent more or less; but the best results are attained when it is made so as to set on the tangent line. The object in setting the bottom G on the tangent is to provide a free surface along which the water will be thrown after striking the closed or inner end of the bucket. If the bottom were set on the dotted llne G in Figs. 4 and 5, the free backward movement of the water would be somewhat obstructed, producing a counter effect instead of being utilized as power.

By my preferred construction the inner end of the bucket is always clear, so thatthe force of the j et is unbroken by accumulated or eddying water. The greatest power that can be exerted by the momentum of the water is when the latter acts on a hinge or on a line parallel with a tangent to the wheel.

The top of my bucket is set approximately at a tangent to the wheel, so that when its outer lip, G, passes the inlet-port the jet moves parallel to the inner surface thereof and strikes the inner end, as shown by the arrow marked J in Fig. 4. As the bucket is driven forward the jet retains its relative line with the wheel, while the closed end of the bucket is given new relative positions to the line of the jet, so that the latter is directed at all times against the inner end or bottom of the said bucket, as will be understood by reference to the arrows J and J which indicate, respectively, the relative lines of the said jet in its first and last contact with the bucket.

Theprinciple on which my device is constructed and depends is the utilization of the percussive force of the water thrown in a straight line, which force is determined by the weight behind the chute or jet, or, in other words, by the number of pounds of pressure to the square inch exerted by the body of water from which the jet is thrown. The jet pro- 7 jected against my bucket strikes thelatter with a force equal to the pressure of the water.

These tops and The elliptical form of the'bucket permits the jet of water to be broken and disintegrated and thrown backward or outward from the bottom or hollow apex along the sides of the bucket in a spray.

The inlet-port A is arranged to throw the jet on atangent to the wheel, or on aline beyond .the periphery of the said wheel and parallel with the tangent. vTwo or more inlets may be employed, if desired. Each inlet is to be arranged, as described, for the single jet.

The wheel may be used equally well in a horizontal or vertical position. When arranged to work in a horizontal position, the shaft B must be supported in a vertical position, as willbe readily understood.

It will be observed that the shank G is set to one side of the longitudinal center of the bucket, so that when the latter is secured in place an equal portion of the bucket will come on each side of the plane of the wheel, as shown in Fig. 3. The mouth of the bucket inclines rearwardly and upwardly, so that the edge of the top is set far back of the edge of the bottom, as most clearly shown in Figs. 4 and 5. By this construction the buckets, when arranged upon the disk, have the rear end of one bucket overlapping the forward portion of the bottom of the preceding bucket, and the jet of water will strike the inner end of each bucket only, and will play upon the bucket next in order the moment it begins to leave the bucket immediately in advance thereof, thus utilizing the force of the water tothe best possible advantage. The water as soon as it strikes the bottom of the bucket is deflected outward and backward, not against the sides of the casing to create friction between it (the casing) and the wheel, nor yet back against the incoming water to retard its momentum, but in an outwardly and rearwardly direction, as previously intimated, that will permit it to escape without producing any lost motion.

Having thus described my invention,what I claim, and desire to secure by Letters Patent,

The combination, with the case and the wheel, of the buckets having the end of one bucket overlapping the bottom of the preceding bucket, each of said buckets having the top and bottom oppositely inclined and tangentially arranged to the wheel, and having the end of the top set beyond the end of the bottom, and having the sides substantially parallel and the inner endclosed and rounded, substantially as shown, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
