IMPROVEMENT IN TURBINE WATER-WHEELS.

HPO-

The Schedule referred to in than Letters Patent and making put of the Ilma.

To all lwhom tt may concern Be it known that we, P. H. LAMEY and A. J. BEAOHELL, OlPOrt Treverton, in the county of Snyder, and State of Pennsylvania, have invented a nevr and improved Tater-Wheel; and I do hereby declare that the following is a full, clear, and exact de'- scription of the construction and operation of the same, reference beiughad to the accompanying draw` ing, making a part of this specification, in which the figure is represented by a horizontal section.

This invention consists in making the outer part of each of thebuckets of a Water-wheel a swinging gate, hinged to the inner lrigid part; also, in so placing such swinging gate as that it shall be at right angles, or nearly so, to the direction of the current f water that acts upon it, so that the latter may strike it full on the side; also,lin providing horizontal surfaces of triangular shape, the broad ends of which meet the lower euds'of said swinging gates, so as to afford. a foundation for the current acting against the face of the gate; also in `providing three reacting-surfaces, and both side and bottom-Vents to each bucket.

In the drawings- A represents a water-wheel of ordinary construction, except as to .the features to be hereinafter recited.

Each of the buckets of our Wheel is made with a rigid innerl part, a, and an outer part, a', hinged to said inner part.' The joint a" of each swinging gate, a', is situated in rear of a line passing from the outer edge of the gate to the centre of the axis of the Wheel, so that the instant any hard matter, such as sticks, stones, or the like, by accident enter within the casing, and lodge Where the outer ends of the buckets strike against it While passing, owing to the jointure of the part a', it may yield to any such obstacle, and fracture thus be avoided.

We give the outer gate a of each bucket a direction such that the entering current strikes it squarely ou the side, and thus We are enabled to get from this impact the full force of the water. result is also the construction of horizontal surfaces,

b, of a triangular form, where'of the apex of each sur-- face is in rear of the outer side of one bucket, and its base at the foot of the front side-'of .the next succeeding bucket, so that each surface, b, conducts the current straight to its bucket, and aiords a foundation for itsaction while thus operating.

To secure a suicicncy of reacting surface we prolong the rigid part a of each bucket a good distance on an angle, obtuse as to the swinging part a', and leave a vertical vent between each pair of buckets.

We also provide a bottom-part, c, to each bucket, coextensive with the side a, and of proper inclination, and we leave a vent between each bottom-piece and its neighbor. XVe also provide a third reacting vertical surface, d, ou the front side of each bottom-para;

c, so that the sides a., c, and d form oneenclosure. By the time the water passes from these enclosures, our notion is that its force is pretty nearly exhausted, and that our construction enables us to get all the power of the liquid possibly extract-able from it. Having thus described our invention, Whatwe claim as new, and desire to secure by Letters Patent, is- 1. The hinged part a', in combination with the rigid part a of the bucket, substantially as described.

2. The horizontal triang'ular surface l1, in combination with the part a', substantially as described. P. H. LAMEY. Witnesses: A. J. BEACHELL.
