JAMES ARMSTRONG AND HARDY HERRING, OE NEAR LISBON, NORTH OAROLINA. y

IMPROVEMENT IN WATER-WH EELS.

Specification forming part of Letters Patent N o. 4,963, dated February 9, 1847.

T0 all whom it may concern.-

Beit known' that We, JAMES ARMSTRONG and HARDY HERRING, of Near Lisbon, in the county of Sampson and State of North Caroliua, have invented a new and useful Improvement in the Construction of Reaction Tater-Wheels, which is described as follows, reference being had to the annexed drawings Of the same, making part of this specification.

. Figure lis a side View` Of the wheel and' crank-sh aft, the hollovvr frustum of a cone-case surrounding the spiral buckets and attached thereto being removed in Order to show the shape of the buckets and the spiral Watercourses between them. Fig. 2 is a perspective view of the Wheel, the case being in the proper place. Fig. 3 is a View of the end of the wheel in which the issues are formed.

A is the core of the Wheel, made in the shape of a solid frustum of a cone. B are the spiral buckets surrounding or winding around said cone in spiral lines. or Water-courses between said buckets. C2 are the inlets. C3 are the issues. D is ahollow case made in the shape of a hollow frustum of a cone, encircling said buckets and secured to the outer edges of the same by any suitable means, said case being banded by iron bands D2 to strengthen it. F is the shaft. G is a crank on the shaft.

Thebuckets are Of the same Width throughout their entire length spirally, but are not of the same thickness, being made much thinner at the inlet, or where the Water is admitted, than at the outlets, or Where the Water is C are the spaces charge in small streams with great effect, th

Wheel turning in a contrary direction to that in which the Water escapes, as in all reaction Water-Wheels, and not requiring more than one-half the quantity of Water than is required tO turn the Hotchkiss and other Wheels in use to produce a given amount of Work.

The end of the core of the wheel next the inlets is made rounded or spherical, so as not to impede the Water or interfere with its free passage to the aforesaid spiral Water-courses.

We do not claim combininga cone, conical hoop, and curved floats, nor of surrounding spiral buckets on a conical hubby a conical hoop; but

What We claim as our invention, and del sire to secure by Letters Patent, is-

The combination of the frustu-m of a solid cone A, frustum-of-a-cone hoop D, and spiral wedge-shaped floats O, substantially of the form and in the manner herein set forth, for the purpose of forming a frusturn-of-a-cone Water-Wheel of the precise form and arrangement represented in Figs. 1 and 2, and as de` scribed above.
