PATENT FFICE.

DIRECT-ACTION WATER-WHEEL.

To all whom t may concern.-

Be it known that I, STEPHEN HADLEY, J r., of Lyman, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvementsin Water- Wheels; and I do hereby declare the following to be a full, clear, and exact description thereof, reference .being had to the accompanying drawings, in which- Figure l is an elevation; Fig. 2, a Vertical section; Fig. 3, a plan of the buckets; Fig. 4., the suspension-plates; Fig. 5,aplan of chute; Fig. 6, a plan of lower frame.

My wheel is divided for the purpose of using the water by impact or percussion alone withoutany aid from reaction or centrifugal force.

The course of the water through my wheel is ina straight line, which I conceive to be important to obtain its full force, and as the water passes onward with accelerated velocity I adapt my curves and increase the diameter so as to effect this object, causing the iow to be natural and with the least disturbance.

The construction is as follows: I form a suitable frame-work a as a base, at the center of which there is aspherical projection b upward, so constructed as to be adjusted by setscrews. Upon this pivot b the lower end of the spindle or shaft rests. This part of the shaft is enlarged, and on its lower end there is a concavity c, just fitting the pivot and forming the bearing of the shaft. Six pillars g (more or less) project up from the baseplate d and sustain the chute d, which is cast with a iiange for the purpose of attachment to said pillars. Below this plate there is attached a bellshaped cap e, that just covers the buckets of the wheel, to be-presentlydescribed, said buckets running close underneath it. Above the lian ge the chute ascends in a true spiral scroll for a single turn and then projects upward ina straight line f to the forebay or other place of supply, gradually enlarging in diameter to the top,in which lI generally place a revolving or other sufii- 'two rings being concentric and connected by radial arms. Between these two rings there are three or more conical rollers m', placed radially and having set-screws through the outer ring to set them up for adjustment. The inner ring just fits and surrounds the collar of the upper bearing. Above these attachments there is a stout bevel or other gear-wheel'n, made conical on the under side corresponding with the disk below and resting upon the conical rollers. This gearwheel it is firmly keyed to the shaft, which is thus principallly sustained as the wheel revolves. The wheel is of a bellshaped form, an outline of which is shown at p p, Fig. 2. The outer surface is concaved in its elevation. This forms the hub or base upon which the buckets s are affixed. These buckets run spirally around the hub, gradually diminishing in cross-section as they approach the periphery. They are in shape a semicircle in their cross-section, or nearly so, being twisted to the curve, so that the water passing straight through the wheel shall have its course at all times perpendicular to the bucket, the straight line being Amaintained by the bellv or concave form of the base upon which said buckets are fixed. The form and proportions of this part of the device are very importantras upon them depend the full effect of my invention. They must be so formed and arranged as that the water shall pass through the wheel in a straight line without deflection, the face of the wheel assuming the proper concave for that purpose. The bucket must be so curved as to have the water acting perpendicularly iipon it, and, lastly, as the wheel increases in diameter from the commencement of the bucket to its termination the bucket shall diminish in capacity as the water becomes diffused, and thus the velocity of the two becomes more equal.

vThe stationary cap over the buckets confines the water to its proper course. and thus aids t-he eect.

Whole are required to produce the best effect, which I attain.

2. The adjustable collar, beve1-wheels, and gear-Wheel combined to tram and sustain the Wheel and adj ust it perfectly to the stationary parts, as herein set forth. I

3. In combination with the above-described wheel, the stationary cap inclosing the moving buckets, as above specified.
