IMPROVEMENT IN 'WATER-WHEELS.

The Schedule referred to- 1n these Letters Patent and making part of the same Beit known that I, JOHN L. FRIsBIE, of the city of Hillsdale, in the county of Hillsdale and State of Michigan, have invented a certain newand Improved Tater-Wheel; and I do hereby declare that the following is a full, clear, and complete description ofthe same, reference being had to the accompanying drawings making part of this specification, in which drawings- Figure lv is is a side view of the water-wheel.

Figure 2 a vertical longitudinal section.

Figure 3 is a View ofthe outflow side of the wheel.

Figure 4 a view of the intow side.

Like letters of reference refer to like parts in the several views.

Objective.

The object of this invention is to economize water in its use as a -niotor'for drawing machinery hy'receiving. its full and direct force upon a pair of wheels, and confining the volume of water in course tothe wheels until its force is expended in the manner as hereinafter set forth.

Descriptive.

In iig. 2 A B represent a pair of wheels of equal size, around the periphery of which are buckets, C, of any desirable dept-h, and of equal distances apart, and in width eorrespomling with the face of the wheels. Said wheels are inclosed in a case or curb, D, corresponding to the width and circumference of the wheels.

In one side thereof is cut a throat, E, a full view of which is shown in fig. 4.

Said throat corresponds in width with the space between the faces of the wheels, or distance that the faees'of the wheels are apart. On the opposite side of the case or curb, at the point where the extreme ends of the buckets describe a circle and begin to divide, descends the point a of a double scroll or center-piece, G, Fig. 2, which also describes the same circle as that of the extreme ends of the buckets for a distance about equal to .the space from the point of one bucket to the point of the next. At this point an opening, H,.is made in the side of the curve on each side at the end of the scroll or centerpiece, the two openings H being about twice the capacity of the opening E, a full view otwhich is shown in iig. 3.

Each wheel is alike provlded with a shaft, I, one end of which runs upon a step in the bottom "of the curb, whereas the opp'osite end penetrates the caseabove, and has its joui-nal seat therein.

To the projecting end of each shaft is keyed a cog# wheel, J said wheels have an equal pitch, and correspond in size at the pitch-line with the circle described by the extreme points of the buckets of the wheel within the case.

Operation.

The opera-tion of the above described device is as follows:

The water 1s conducted through an ordinary pipe or ume to the throat Epas indicated by the arrows, iig. 2, where it impinges upon the buckets C, which are so geared that one fl'om each wheel meet at the center line, and form a direct resistance tothe stream, and, as resistance yields to force, the wheels move together in direct-ion of the arrows until the points of the buckets reach the point a of the double scroll.

The stream then divides, one-half passing on one side of the scroll, and the other to the opposite side. The buckets continuing the resistance until the next pair unite in their course in the center, as aforesaid. The distance from the point of the center-piece to the point i' discharge is equal to that of the distance from the point of one bucket to the point of the next, so that as soon as one bucket reaches the point ofthe scroll, thereby cutting off the forceof the water from its head from the preceding one, said preceding one has reached the point of discharge, and the water is allowed to escape at the instant itsjforce is expended, hence it is not carried on to create friction, or otherwise impede the free action ot' the wheels in their rotary movement The water having expended its force is discharged through the openings H, at the ends of the scroll, by centrifugal force.

By this device the impulsion of the streamis 'equal to on each wheel without any reaction, and is transferred to one shaft by means of the cog-wheels J J running in conjunction, as above said, for driving machinery.

What Iclaim as my invention, and desire to secure by Letters Pat-ent, is-

'lhe wheels A B, provided with buckets in a taugential line, and operating in relation to each other,

in combination with the double case or curb D, having an induction-opening E, and eduction-openin gs H H, with the center G between the openings H H, operating conjointly, substantially as and for the purpose set forth.
