IMPRVEMENT IN WATER-WHEELS- The Schedule referred to in these Letters Patent and making parigi the same.

To all whom it may concern:

Be it known that I, BENJAMIN I. T'ALBOTT, of Iowa Falls, Hardin county, State oi' IoWahave inventedfcertain new and useful Improvements in Water- Wheels, and their appurtenances; and I do hereby declaro thatthe same are described and represented i'n the following description and accompanying drawings,

p so as to enable any person skilled in the art to make and use the same, without further invention or experiment.

The object of my invention and improvements is to so arrange and construct awater-wheel and its appurtenances, that it, with its gate, curb, andimmediate surroundings, may be made in few pieces and cornpleted and put together at the foundry, or machineshop, ready for use, 'and be transported whole, so that when it arrives at its'destination a hole may be cut in the bottom of a box or rlume,^and the wheel set into it, and it will then be ready for the water, which may be let in to turn4 the wheel.

- The nature of my invention consists in providing a cylindrical curb or case around a water-wheel, for'its protection, having an inside flange at the top, and an outside ilange at the bottom and in arranging a cylinder within the wheel, with openings for admitting water to the Wheel, the same having an outside ange by which it is supported, and a bottointo support the weight of the water above; also, in ,providing a cylinder, fitting in the one last mentioned, supported also by a fiange at the top, and having openings for the water to pass through corresponding to those of the cylinder outside of it, 4but movable, so as to regulate the quantity of water'admitted to the wheel; and in providing aspider-frame fastened to the outside curb or case for supporting the step of the wheel-shaft.

In the accompanying drawings- Figure l is a perspective view of .the cylindrical curb and its flanges, with s ueh other parts as may be readily seen. i

Figure 2 is asection of the wheel and its belongings, eut vertically through the centre.

Figure 3 is asection of the wheel, cylinder, and gate, below the line z z on fig. 2.`

In these 'drawings- D is a cylindrical curb, made larger than the wheel p A, so as to permit the water issuing from tile-wheel to pass down freely betweenl it and thecurb.

`I prefer to make this curb of cast-iron, with a flange, E, on the outside'at the top, to rest on the bottom 'of the Huma-and support the curb when the wheel is set in its place for operation; also, with a flange, F, on the inside, to project over the top of the wheel, as shown in the drawing, to support the cylindrical ease B, fitted to the inside of the flange F and wheel A, and supported by a flange on the outside, at 4the top, resting on the flange F.

The case B extends down through the wheel A, as shown in the drawing,v and is provided with a bottom, G, to sustain the water above, so as to prevent it from pressing downward on the arms A3 ofthe wheel, and increasing the friction in the steph a of the shaft A1.

' This shaft'passes up through a hole in the bottom G, and is held above the wheel by the frame H, fastened to the ilange F, as shown ink the drawing.

The arms A3 are fastened to the lower rim of the wheel A, and to the shaft A1, which is turned by the wheel, and may be provided with a pulley, or gear, or coupled toauother shaft, to turn machinery.

The m'ms A A of the wheel are connected by the buckets A, which may be made in the form shown in g. 3,'or in such other form as may be preferred.

The cylindric case B is provided with openings e, for

Vthe water to pass out against the buckets A2, to propel the wheel.

To close the openings c c, I make a second cylinder, O, to fit the inside of B, with openings vcorresponding to the openings c c in the case B, as shown in g. 3, and provide it with a flange on the outside, at the top, to rest' and turn upon the top of the ease B, so that it may be moved to open or close the openings'c c, and

thus 'regulate the quantity of water admitted to the wheel.

'loturn the cylinder G, I fit a shaft,.02, to turn in the flame H and iiange F, with a pinion, O1, on it, to take into the teeth C on. the flange of the cylinder C, as shownin iig. 1.

The bridge-tree I is fastened to the'curb D, to sup-` port the step'a ofthe shaft A1 of the Wheel.

lhis wheel and all its appurtenances may be made at a. foundry or machine-shop,and`f1tted together, and

transported, without being separated, to the place Where it is to be used p The principal advantages of ymy wheell are- First. The wheel itself is made very Wide or of great diameter, in order to give greatleverage tothe water. acting upon the buckets; and the buckets are made,

very shallow andwith a small issue, so as to occupy only a narrow rim at the verge of the Wheel; and the height or length of. the buckets is very great in order to give them sufficient capacity for the necessary amount ofwater; the inner ends of the Vbuckets are curved to iit the' outer curve of the hollow cylinder B,

while the whole face of the bucket is presented -to the direct action of the water-shoot,and to the constant pressure of the copious volume of water, settling steadily down within the cylinder B, thus preventing agitation and broken currents and consequent loss of power. Second. The hollow-slotted cylinder B is of such4 shape as to be easily cast and nished, and not liable to strain or crack in cooling, as Would'be the case if cast with a central small' cylinder enclosing the shaft ofthe wheel;- and this cylinder,l beingboth broad vand high,

brings a full volume of water, in a state of comparative rest, to occupy about fteen-sixteenths (HL) of the entire diameter of the wheel; and from this cylinder the water has to ow only an inch to strike the 4full face of the buckets at the rim or extreme verge of the wheel; at the same time this cylinder relieves4 l especially the hollow-slotted cylinder B with the shaft I passing through a hole in the bottom of the cylinder,

and through the water in which it revolves, so that l the whole space inside of the buckets isr occupied by a broad column of water in a comparative state'of rest.

Having thus fully described my invention,

1. The hollowrcylinder B, and the gate 0,'in combination with the .shaft and wheel, substantially as set forth.

2. A turbine-wheel, consisting of the wheel A, the registering interior and exterior cylinders B and O, with the register-operating. mechanism c1 c2 c3, the projecting cover F E, and the Vshaft A', stepped upon the 1spider I, all combined, arranged, and operating silbstantially as set forth.

In testimony that I claim the foregoing as my own, I affix my signature, in presence of two Witnesses.

Witnesses: B. I. TALBO'IT.
