CURRENT-TURBINE.

To all whom it may concern:

' Be it known that I, ALoNzo H. PERRY, a citizen of the United States, residing at Bartlesville, in the State of Oklahoma, have invented new and useful Improvements in Current-Turbines, of which the following is a specification.

The purpose of the present invention is to devise a motor wheel designed most especially for utilizing the force of flowing water such as streams, flumes or the like, said wheel being of such construction as to admit of its being wholly or partially submerged in the water and adapted to be placed either in vertical or horizontal position according to the direction of flow of the water.

One object of the invention is to provide against interference with the power transmission shaft by ice in the event of the mechanism being located in a stream so as to be exposed to the weather.

A further purpose of the invention is the construction of a turbine wheel in which the discharge from the blades or wings may be regulated to suit the pressure or head of water by means of which the wheel or turbine is set in motion.

The invention consists of the novel features, details of construction and combinations of parts which hereinafter will be more particularly set forth, illustrated in the accompanying drawings and pointed out in the appended claims. I

Referring to the drawings forming a part of the specifications: Figure 1 is a detail view of a current turbine in operative relation, the mountings being shown in section and the wheels in side view. Fig. 2 is a front View of the turbine wheel. Fig. 3 is a detail view in elevation of a portion of the turbine wheel as seen from the rear showing more clearly the adjustable blades. Fig. 4: is a horizontal section on the line 41 1 of Fig. 2 looking in the direction of the arrows. Fig. 5 is a detail perspective view of one of the blades or wings. Fig. 6 is a perspective View of one of the adjustable blades.

Corresponding and like parts are referred to in the following description and inclicated in all the views of the drawings by the same reference characters.

It is to be understood that the turbine wheel may be placed vertically or horizontally according to the direction of flow of Specification of Letters Patent.

the Water whose power is adapted to be utilized for driving the machinery to be operated.

The wheel may be mounted upon a shaft 1 and is preferably secured to said shaft so as to rotate therewith. The turbine comprises a hub 2, a series of blades or wings 3 extending outwardly from the hub, and a rim 4 encircling the blades and secured to the outer ends thereof in any convenient and substantial manner. The blades 3 have a slightly tangential arrangement this being -to receive the impact of the water in the manner well understood. The rim 1 serves both to connect the outer ends of the blades 3 and also to confine the water and prevent radial displacement thereof by centrifugal action when the turbine is in operation. lVings 5 project from the rear edges of the blades 3 at an angle thereto preferably at about 35. The wings 5 incline in the same direction and the spaces formed between them constitute discharge passages for the spent water after acting upon the blades 3. The turbine, including the hub 2, blades 3, wings 5 and rim 4. may be cast or constructed in any other manner. The blades and wings are preferably formed of sheet metal cut into the required shape and having portions bent to provide the blades 3 and wings 5 and secured at their ends to the hub and rim in any way. Other blades 6 are adjustably connected with the wings 5 to admit of varying the width of the wings 5 so as to regulate the discharge and hold the water in contact with the blades 3 for a greater or less time according to the head or pressure of said water and the desired velocity of the turbine to suit the particular work in hand and the flow of the water by means of which the turbine is operated. The wings 5 have transverse slots 7 and the adjustable blades 6 have openings 8. Bolts 9 pass through the openings 8 and slots 7 and serve to secure the blades 6 in the desired adjusted position.

The turbine may be mounted in any manner. As shown in Fig. 1 the shaft 1 is arranged in horizontal position and the turbine vertically, said shaft being mounted in beams 10. The end of the shaft 1 is received in a bearing 11, which is secured to a beam 12, said bearing being closed at its which is in mesh with a. bevel gear 16 fast to the shaft 1. A sleeve 17 is mounted upon the vertical shaft 14 and is arranged so as to project above and below the level of the stream in which the turbine may be placed. The sleeve 17 is larger than the shaft 14 so as to leave a space between said shaft and its inner walls. The sleeve is closed at its ends in such a manner as to prevent water entering the same and to maintain an air space at all times. A set collar 18 supports the sleeve 17 upon the shaft 14 at the required adjusted posit-ion.

The purpose of the sleeve 17 is to prevent the formation of ice in cold water binding and otherwise interfering with the free rotation of the shaft 14. In the event of ice forming upon the surface of the water, 19,

the sleeve 17 willbe held fast and constitute abearing for the shaft 14 which latter is adapted to rotate freely therein.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the inventiomwhat is claimed is: i

1. A turbine comprising a plurality of blades arranged at an angle to the plane of the wheel, and adjustable means carried by said blades for choking the vent thereof.

2. A turbine comprising blades arranged at an angle to the plane of the wheel and provided with wings projecting from the inner or rear edges of the blades at an obtuse angle thereto, and other blades adjustably connected with the wings and movable toward and from the first mentioned blades.

3. A turbine comprising tangentially arranged blades set at an angle to the plane of the wheel and having wings extended at an obtuse angle from their inner or rear edges, and other blades fitted to said wings and adjustable thereon toward and from the first mentioned blades.

4. A turbine comprising a hub, a rim, blades having connection at their ends with said hub and rim respectively and provided at their rear edges with wings extending therefrom in the same direction at an angle of about thirty-five degrees, and other blades adjustable upon said wings toward and from the first mentioned blades.

5. A turbine comprising a plurality of ALONZO H. PERRY.
