JOHN TYLER, OF OLAREMONT, NEW HAMPSHIRE.

IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 130,608, dated August 20, 1872.

Specification describing certain Improvements in Water-Wheels, invented by JOHN TYLER, of Glaremont, county of Sullivan and State of New Hampshire.

Nature and Objects of the Invention.

- as will be fully set forth hereafte Description of the Drawing. Figure 1 is a bottom View of the wheel. Fig. 2 is a side elevation. Fig. 3 is a horizontal section; and Fig. 4 is a vertical cross-section.

Similar letters of reference indicate corresponding parts in the drawing.

General Description.

The bucket-head a of my improved waterwheel, and the buckets b b descending from said head, are to be inclosed in a scroll-shaped water-Way, as shown and described in the reissued Letters Patent N 0. 4,539, dated August 29,1871, to which reference is herewith made; and the general arrangement of the waterway, gate, &c., for this wheel is the same as described in said Letters Patent. In my former patent the buckets were straight on the vertical line upon the periphery of the. wheel, and also at their central termination upon the convex portion of the bucket-head, and the po sition of the buckets upon the head is that of an eccentric curve, as will readily be seen, and the internal edges of the buckets are narrowed in their area as they approach the center. -In the present invention the buckets b are made in the form of an irregular curve from the pea riphery to their central termination, as shown in the drawing, their lower edges terminating invention,

in an irregular scroll overlapping each other, and nearly in a plane with the under surface of the wheel. The peculiar shape of these buckets b will be readily understood by any person familiar with water-wheels, by an inspection of the drawing rather than by an elaborate description thereof. The wheel is cast solid-or, in other words, all the parts are cast together at one operation--by means of cores and proper-shaped flasks. .The lower edges of the series of buckets b are connected together by the rim 0, as plainly shown in the drawing. In the present invention the apertures for the discharge of the water are contracted and made much smaller than in the previous Letters Patent above referred to. The primary object of this construction of the buckets is to obtain a greater lifting action of the water upon the buckets, and thereby relieve the wheel of a great portion of its friction upon the step in which the sh aft rests, and thereby greatly contribute to the useful effect and power of the wheel. The general construction of the buckets b is such as to give the greatest and most economical effect of the water upon the wheel.

The elevated cover, packing-box, arrangement of gates, &c., and the general advantages described in the former patent referred to will be applicable and true with my present and a further "or detailed description is unnecessary.

, Having thus fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is i 1. The series of irregularly-curved buckets 12, combined with the curved bucket-head a, substantially in the manner set forth and specified.

2. The irregularly-curved buckets b formed with and projecting from the curved surface of the bucket-head a, substantially as herein set forth.

Witnesses: JOHN TYLER.
