UNITED STATES PATE EEICE.

IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 117,451, dated July 25, 1871.

To all whom it may concern:

Be it known that I, CHARLES WATKINs PAE- KER, of Genesee Forks, in the county of Potter and State of Pennsylvania, have invented a new and valuable Improvement in Turbine Vater- Wheels 5 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this speciication, and to the letters and iigures of reference marked thereon.

Figure 1 of the drawing is an end View. Fig. 2 is a vertical section through the diameter of the wheel. Fig. 3 is a face View of the shaft and buckets detached from pen-stock. Fig. 4 is a vertical section across the shaft and pen-stock.

This invention has relation to turbine Waterwheels g and it consists in the employment or use of a series of buckets which are placed longitudinally and eccentrically on the shaft, with inclined planes between them, in combination with a series of curved or spiral buckets at each end of the longitudinal buckets, the whole placed within-a case or pen-stock and arranged as hereinafter set forth.

' In the accompanying drawing, A represents' or spiral position on the shaft A, the spaces between them gradually decreasing in width from their inner to their outer ends. The width of the outlets at their outer ends is the same near the shaft A as at their outer extremities, a peculiar twist being given to the buckets in order to make their outer ends parallel with theends of the pen-stock, or at right angles with the axis of the shaft A; consequently, the discharge is equal at all points ofthe openings, rendering thepressure of the water more equal than results from other arrangements, and limiting the area of the discharges in keeping with th-e capacity and form of the wheel. The whole is surrounded by a case or pen-stock, E, the curved buckets being encompassed by a projecting rim, F.

rllhe water iirst acts upon the central buckets B by impact or direct action, and is deiiected by the inclined planes toward the end buckets C G, upon which it acts by a reactive iniiuence and escapes through the outlets between them.

It is obvious that the peculiar twist mentioned as being applied to these buckets presents a more considerable area of surface for this reactive influence of the water than any form hitherto devised, and consequently increases the percentage of power.

l claim as my invention- The water-wheel herein described, having the plane bucket B tangentially placed with reference to the shaft A, the curved end buckets C G, and the intermediate inclined planes a a tapering from the central portion of the wheel each way toward the shaft, substantially as speciiied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

. CHARLES WATKINS PARKER.
