TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 295,590, datedMarch 25, 1884.

Application filed February 6,1883. (No model.)

Be it known that I, ISAAC SHEROK, of Fremerit, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Turbine Water-Wheels; and I do hereby 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 pertains to make and use the same.

My invention relates to an improvement in turbinewatenwheels, and more particularly to that class thereof in which the water is admitted to the wheel through the periphery of a chute-ring surrounding it; ithe object of the invention being to provide a wheel of the character designated with an improved ring-gate.

A further object of the invention is to provide a wheel with a ring-gate arranged so as to be relieved within and without from waterpressure.

A further object of :my invention is to pro Vide improved means for mounting a ringgate within a wheel whereby the resistance of friction is reduced to the minimum, the slight wear falling on the gate being so compensated for that the elliciency thereof is unail'ected.

A further object of my invention is to provide means for maintaining the inner casing and the chute-ring in their appropriate positions, and preventing them from interfering with the action of the ring-gate, which is interposed between them, such devices serving also the secondary function of excludingsan from the gate. A further object of my invention is to provide a wheel with a gate adapted to be carried through the whole range of its adjustmeet without changing the ang e at which the water is impacted on the wheel. WVith these several objects in view, my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of a turbine wheel constructed in accordance with my invention. Fig. 2 is a view thereof in vertical cross-sea tion. Fig. 3 is a view in perspective, embracing the inner casing, the bed, the crown-plate, and the sleeve. Fig. 4 is a view of the chutering. Fig. 5 is aview of the ring-gate. Fig.

6 is a View of the guardwring; and Fig. 7 is a view of the wheel in horizontal cross-section. The cylindrical casing A, within which the wheel is located, rises centrally from the bed 13, 5 5 the said parts being preferably cast integral. If desired, however, they may be'made separate and secured together. The casing is provided with a series of apertures, O, the rear side walls, D, of which are beveled, while their forward side walls, D, are curved. The object in curving the walls D will be set forth hereinafter. The contour of these side walls is best shown in Fig. 7 of the drawings, in which the arrow indicates the direction in which the wheel rotates.

The crown-plate E is reinovably secured to the upper edge of the casing A by bolts or equivalent means. In virtue of this construction the plate may be removed, leaving the wheel exposed and permitting it to be removed or repaired without disturbing the parts located without the casing.

The chute-ring F is provided with a series of apertures, G,havingbeveled side walls and cor- 7 5 responding in number and position to the apertures G in the casing. The ring is further provided with an upper bearing-ring, II, and a lower bearing-ring, I, the said bearing-rings being downwardly inclined in the same plane for the purpose of. elevating the water a little before its impact on the buckets of the wheel. WVings .I located between the rings H and I are designed to deflect the water into the apertures G aforesaid. 8

The horizontal extension K of the bed 13 is provided with an annular recess, L, and with a shoulder, M, the lower face of the ring Ibeing suitably cut away to fit down upon the said extension to which it is rigidly secured by 9c screws or equivalent devices. By fitting the said parts together, as above described, the displacement of the chute-ring is prevented.

The inner edge of the guard-rin g N is adapted to fit closely around the upper portion of the 5 casing A,while its outer edge is provided with a depending flange, 0, arranged to fit in an annular recess, I, formed in the outer edge of the ring H, to which the ring is attached by screws or equivalent devices. In virtue of 1c this construction and arrangement of parts, the guard-ring is made to form an additional safeguard against the displacement of the chutering. The guard-ring is further provided with two segmental slots, Q, opening into the space R, located between its upper face and the upper face of the ring H, and occupied for the most part by the flange U of the gate-ring U. The bent ends b of the arms T of the framework V extend into and play in the said slots, the said ends of: the arms being attached to the flange of the ring-gate.

The frame-work V, which is provided with a rack, X, is fitted over and arranged to move on the sleeve 7 as a pivotal center. A pinion, Y, journaled in the frame Z, secured to the crown-plate E, meshes with the rack X and actuates the frame-work and the ringgate. Gaps A, adapted to cover the slots Q, in the guard-ring, are designed to prevent sand and other abrasive substances suspended in the water from entering the spaces It and B, the latter being the space between the casing and chute-ring in which the ring-gate is located. The said caps are provided with apertures O to receive the ends of the arms T. As the frame-work is moved from side to side, the ends of the arms play in the slots Q, the caps being moved over the surfaces of the guardring without, however, exposing the slots.

The ring-gate U, which is located in the space R, before referred to, is provided with aseries of apertures, E, corresponding in number and position with the apertures O and G of the casing A and chute-ring I respectively. The flange U of the ringgate has bearing upon the ring H of the chute-ring, as shown. Inasmuch as the ring-gate is interposed between the inner casing, A, and the chute-ring I it is practically relieved of all water-pressure, and as there is no pressure of water upon its flange U, the force to be overcome in operating it is chiefly represented by the friction of the said flange upon thebearing-ring H. This friction being very slight, the parts are in a great measure preserved from wear, but all wear, however inconsiderable, is compensated for by leaving a space, F, between the lower edge of the gate-ring and the bed, so that as the flange U wears away the ring-gate is permitted to descend and take up the wear.

The form of ring-gate which I have shown is the one which I prefer to employ; but it is evident that so far as the form and position of the flange U are concerned that the gate may be modified.

The chute-ring and the inner casing are rigidly secured together in such relative positions that the curved walls of the apertures of the latter will be a little in advance of the beveled walls of the apertures of the former, In virtue of this relation and of the curved contour of the forward side walls, I), of the apertures of the casing, the water in entering the wheel will not be retarded by contact with the inner casing, whether the ring-gate is adjusted to admit the full head of water to the wheel or only a part thereof. I

It should be observed, that although the limit myself,

, ring-gate is rotated in regulating the amount of water supplied to the wheel, the angle at which the water is impacted on the buckets is not changiedg th ns insuring a uniform and steady action of ti e wheel.

I would have it understood that I do not to the exact construction shown and described, but I hold myself at liberty to make such changes and alterations as may be considered to fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
