THOMAS N. EGEItY, OF BANGOR, MAINE.
IMPROVEMENT IN WATER-WHEELS.
Specification forming part of' Letters Patent No. 149,646, dated April 14, 1874 application filed January 22, v1873.
To all whom it may concern: l
Beit known that I, THoMAs N. EGERY, of Bangor, in the county of Penobscot and State of Maine, have invented certain new and useful Improvementsin Water-Wheels 5 and I do 'hereby declare that the following is Aa full,
l water-wheel the parts of which shall be in such. relation to each other as to utilize more fully the power of the head. It is designed more part-icularly for a horizontal-pressure wheel.
In wheels of this class, when the buckets are perpendicular, the bottom of the wheel has a tendency torun away from the top, since the water acting upon it has a greater head or fall, and consequently more velocity, than that acting uponA the upper part of the buckets; for instance, if the wheel is one foot in height from top Ito bottom, it has been demonstrated that the water at the bottom, having one foot more head, will, in passing around a given circle, come out about three feet in advance of the water at the top, so that the tendency is to carry the wheel around in advance of the water, which would otherwise act upon the upper portion of the buckets. I
obviate this by making the top of the wheel about three feet less in circumference, or, what is the same thing, about one foot less in diameter than the bottom for each foot it is distant from it, and inclining the bucketsy inward at the topi the same proportion. This causes both top and bottom of the buckets to be acted upon equally by the water. I also construct the buckets so as to avoid the concussion ties, the upper part of the outer end of the bucket being the longer, andthe inner end being parallel thereto. This construction both eases the. water as it falls from one bucket to another, and allows it to escape more readily from the wheel after it has done its work.
The wheel is also provided with a rimAat the bottom, which acts as a stop-water, retaining a portion of it under the wheel, and causing it to balance that which falls upon the top.
In the drawing, A shows the wheel, a being the top, and b the bottom thereof; c, the buckets, with inclined ends d e, and slanting iuward from the perpendicular. At f is the shaft, and g the stop-water, as described. h shows the ordinary fiume which may be used.
I do not claim, broadly, inclining the buckets inward from the perpendicular, since if this be not done in accordance with the rule here specified, no good effect is produced. If the inclination be .too great, the top of the wheel will run away from the bottom.
What I claim as my invention, and desire to secure by Letters Patent, is-
l. A Water-wheel constructed substantially as herein described, to wit, having its top as much smaller than the bottom in diameter as the distance between them, and its buckets inclined inward, as specified.
2. Buckets c, having their ends cut slantingly, as shown at d e, as and for the purposes set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 20th day of January, 1873.
