Letters Patent No. 113,400, dated April 4, 1871,

IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in' these Letters Patent and making pari: of the same.

To all whom it may conce/rn Be it known that I, GARDNER Cox, of Pier-pont, in the cennty of St. Lawrence and State of New York, have invented a new and improved W'ater-Vheel; and I do hereby declare that the following is a full, clear, and exact description thereof, which will' enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

rlhis invention relates to a new and .improved waterwheel ot' that class which is secured to a vertical shaft, and consequently rotates in a horizontal plane.

The invention consists in a peculiar construction of the buckets, and a novel application of them to the wheels, whereby a large percentage of the power of the water is obtained.

In the accompanying drawing- A represents a suitable base or platform, in which the lower part of the wheel is fitted and works.

B is the shaft of the wheel, the lower end of which is stepped in the cross-bar- O, iitted and seeured`tothe base or platform in which the wheel is fittedand works. n

The wheel is composed of a hub or hody,1, having buckets, G, attached to its exterior. This hub or body has a concave periphery, as shown clearly in fig. 1, so that the hub or body gradually decreases in diameter in a concave form from its upper to about 'lhe buckets G are each composed of two parts, e and b, the upper and longer parts, 11, being inclined at au angle of from five to thirty degrees with a horizontal plane orthe plane of rotation of the wheel, the

longer or upper buckets?) bending or'eurving down at the lower ends at c, the lower parts of the buckets a bending or curving up at the upper ends, forming a4 connection at c. Theicenter, at c, forms nearly a tlat cymct frectft, which is shown clearlyin tig. v1.

The lower portions of these buckets, whiehinclnde-I the parts a b, are. similar `to those now employed in the ordinary turbine waterwheels, the extension or prolongation of the upper parts l) and the gradual increase of the buckets Ifrom their upper to their lower ends, caused by the concave-exterior of the body F, constituting the main portion of my improvement.

Byhavin g the buckets ci b constructed and applied to theeoncave exterior of the hub or body F of the wheel, as shown and described, the full benefit of the force o i' the impact of the water is obtained, and also the force or power due to the gravity of the water in its discharge from the wheel, the gradual expansion ot the buckets admitting of the free discharge ot' the water, so that the latter cannot serve as a drawback to the wheel.

I 'claim as new and desire to secure by Letters Patent- The buckets a b, united at c' to the external cylin-Y der, arranged as shown, 'when said buckets areattached to the concave periphery of the downwardly-diminishing hub or body F of a wheel, as and for the purpose MARY E. WELCH, HERBERT I. BROWN.
