Description

UNITED STATES PATENT QFFIGE.
ZAGHARIAH W. NEWMAN AND JOHN A. POWELL, OF IUKA, MISSISSIPPI.
IMPROVEMENT IN WATER-WHEELS.
Specification forming part of Letters Patent No. 172,645, dated J annary 25,1876; application filed July 14, 1875. V
' To all whom it may concern:
this specification.
This invention relates to turbine waterwheels; and the nature thereof consists in certain constructions and details to be hereinafter more fully described by the aid of the accompanying drawings and letters of reference marked thereon, in which Figure 1 is a side elevation of the improved wheel. Fig. 2 is a sectional plan of the water-wheel. Fig. 3 is a plan of the gates.
The water-wheel m is firmly attached to an upright shaft, A, and rests upon a suitable bearing, a, and is made to revolveimmediately under the pen-stock and cistern. The water is conveyed to the wheel by the flumes G G, which are opened and closed by the gates D D. The said flumes are constructed so as to compress the water and discharge it at the top of the buckets 0 0 of the wheel M. This wheel is fully shown by Fig. 2, and it will be seen that there are two discharges, o 0 o o and t t t t*. The ts discharge at the periphery of the wheel, at its outside, by perpendicular slits, and the os discharge at the bottom of the wheel, by which means the water gives greatly-increased force to the wheel. By
increasing the diameter of the wheel there can be a great number of bottom and side openings. The gates rest upon the face of the flumes (l O in cistern E, and are merely sheets of metal, which are hinged upon the shaft A at d, andall are perated upon by a simple handle, d
It is well known in water-wheels that the force of the water acting upon the shaft is injurious, and that packing has to be used to prevent the leakage of water, which produces friction, and thereby counteracts the force of the water. To prevent this there is raised for any desired distance around the shaft a funnel or conical tube, N. This separates the water in the cistern and brings it directly out to the fluines. contrivance can be brought above the waterlevel, and thereby prevent the leakage of water upon the shaft.
Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is as follows:
The combination of the vertical shaft A pivoted at a, as described, conical shaft N, cistern E, hinged gates D D, flumes O (J, and wheel M, the several parts being constructed, arranged, and combined to operate substantially as described, and for the purpose set forth.
In testimony that we claim the foregoing as our own improvement we affix our signatures in presence of two witnesses.
