dated September 28, 1869.

IMPROVEMENT IN TURBINE WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that 1,0. B. WALSH, of Waupacca, in

the county of Waupacca, and State of Wisconsin, have invented a new and useful Improvement in the con'-l struction of Turbine Tater-Wheels and l do hereby' declare that the following isv a full, clear, and exact description thereof, reference .being had to the accompanying drawings, and letters marked thereon, mak-4y ing a part ot' thls description, in which- Figure 1 is a representation of a turbine waterwheel, constructed according to my plan.

Figure 2, a perspective representation of the inner hoop and its flange, and shows the position and construction of a part of the buckets belonging thereto.

.Figure 3, a broken view'of the outer hoop and its flange, with one bucket attached.

The nature of the present invention consists in the peculiar arrangement of the buckets, hoops, rim, and iauges, whereby the construction is greatly simplied, while, at the saine time, a' wheel of great power and durability is produced, as the whole is hereinafter fully shown. l

C, figs. 1 and 2, vrepresents the inner hoop, cast solid with a concave flange, F, which has a height from its base to its inner periphery, which is about equal to the height of the hoop, the bottom part of said hoop being castsolid, with a bottom, through whicha hole is made to receive a shaft.V

Buckets K Iare so formed as tolit the concavefiauge F and hoop C closely, as shown 'at' iig. 2, the lower parts of the buckets K having vertical bearings against the hoop, and underlapping the upper parts at P, and being fastened to the iiange and hoop, by means o t' bolts or screws, put through 'the lugs b b', are held firmly in place. And the"relation of the buckets is such to each other that the water passing between Ythem has so much .space at x x, underthe parts I, as not to strike the backs of the buckets and retard the motion of the wheel, while at the same time the curves V, in the faces of the buckets, so

guide the water downward, as not to break the ourrent of water discharged from the upper easement.

The top parts I of the bucketsP are fastened to the hoop C, by means of bolts or screws put through the lugs h, and to the inside of the hoop B, by bolts put through the lugs f, land the upper edgesof the parts K are fastened by means of screws, put through the ange E, the outer edges of said buckets being so formed as to itthe inside of th'c hoop B and flange E.

'The buckets H J are each cast lin one piece, and ,Y

are soformed as to t-the iange E closely, and also 't "the cuire of the hoop B, to which they are fast? hoops, with their concave anges, provide' a conven' ient support for the inner andouterbuckets, and that their relative size and position permit the inner buckets to take water from between the hoops B O,.and

yet discharge it` below buckets H, at the periphery ofthe wheel, while at the same time the outer buck'- ets are taking and discharging water under a like pressure.

The curbing. and setting thislkind of wheel are so well understood that no instructions are deemed necessary.

' Having thus fully described my invention,

What I claim, and desire to secure by Letters Patcnt of the United States, is

The construction and arrangement of the hoops .B O, concave flanges E F, rim A, ambbuckets K I and H J, as set forth. i
