MPROVEMENT IN TURBINE WATER-WHEEL.

Thechdula referred to in these LettarsPatent and vmaking part of the lama.

To all whom it ma/y concern.-

Be it known that I, JOHN JORDAN, of East Windsor, Berkshire county, Commonwealth of Massachusetts, have invented a new and useful Improved Turbine Water-Wheel; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the drawings- Figure 1 is a plan and partial sectional view of my wheel, and

Figure 2, a vertical sectional diagram, showing the interior.

In this wheel, the water is taken in from the outside circumference of the case K, through gateways A A A, tc., and iows out through the centre underneath,

at B, 2.

Gates C O,f&c., are arranged in the gateways so that they may be operated together, and simultaneously, by a peculiar mechanism, which I will now describe.

- Around the central shaft D, and working upon a bearing formed upon the case at the top and around the shaft D, is placed a four-armed frame, E, with adjustable racks F F, &c., arranged so as to extend the arms G G, 86o., of the frame E until the racksproper mesh in with gear-wheels H H, 85e., at one side of each water-gate respectively.

These gear-wheels H H, &c.,'are placed upon the upper ends of shafts I I, &c., which operate the gates themselves by means of the circular rack J on each gate, and a pinion, K, upon each shaft I. i

When the shafts I are revolved by means of *the operation of the gear H by the racks F, the gates O are opened simultaneously or shut, as the four-armed frame Eis turned either way, which is accomplished by means of the connecting-rod L attached to one of the shafts I, and extending upward to the regulatingmechanism above.

As it is sometimes convenient to shut o the water from two or more of the gates, the adjustable arrangement of the racks F upon the arms of the frame E- allows this to be done conveniently, the shanks of the lacks F sliding in grooves, or guides formedin the arms G vof the flame E, and being set by means of bolts N N, &c.

'.lhe construction of the wheel and the alraugement of the water-guides are as follows:

The buckets a a, Ste., are flanges set around the circumference of the -wheelame,`and inclining, from radial lines, in the direction of the flow of water.

On their inner edges, b b, &c., they increase in width from the bottom to the top, the bottom width being of about the same measurement radially as the foundation-platee at its narrowest part, d, or where the waterguides e e, Snc., converge to the circumferential line described by the outer edges, f, of the buckets, these guides being segments of circles set eccentrically to the wheel, and converging from the water-gates toward the wheel, as -just stated. l

-Vertically the buckets a a, 85e., fill the space between the plate c at the bottom and the top of the case O, 'i

and their outer edges are curved backward toward the `flow of water, so as to catch the full force of the stream at these points. y In the operation of this wheel, four convergent streams, (should all the gates be open,) thrown to" ward the centre indirectly bymeans of the waterguides c e,&c., and the inclination of the buckets, operate upon the latter, each stream acting upon the buckets contained between the water-gates and the convergent end of the guides respectively, the guides forming the outer sides of the case.

.The advantages of this construction of wheel are, that the water is most economically used, nearly the full per cent. of power being applied directly against the buckets, and the latter are completely' prevented from being choked by ice, trash, and other foreign matter, their inclination throwing all such toward the centre, where it is washed out by the stream.

Now, having described my invention,

What I claim as new, and desire tol secure by"Let ters Patent, is-

1. The combination of the frame E, having the adjustable racks F, with'the water-gates O, whereby the latter may be opened or closed simultaneously, substantially as described and shown.

2. The combination of the shafts I, having gear H and pinious K, with the circular racksJ upon the watergates @substantially as shown.

JOHN JORDAN.
