Letters Patent No. 96,57 3, elated November 9, 1869.

IMPROVEMENT IN WATER-WHEELS.

The Schedule` referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that we, J. G. FREDENBURR and y WILLIAM V. ANDREWS, of Newcastle, in the 'county jets, through nozzles.

It consists `in the form of the buckets, and the Inanner of connecting them to the rim of the wheel.

The faces ofthe buckets receiving the water represent spiral concaved forms, so shaped as to give the water, which is discharged against them when, in the lowest position, irst, an upward or radial direction, and then a lateral direction away from the wheel, calculated to utilize, as much as possible, theunspent force of the water, which is commonly lost in these wheels by the immediate escape after the impact, and also calculated to discharge the Water away from ythe wheel, so as not to clog or impede its motion, all hereinafter more fully described;

Figure l represents a side elevation of our improved wheel, and

Figure 2 represents vertical and transverse sections of the buckets.

Similar' letters of reference indicate corresponding parts.

casting, and have spiral concave faces, B, for the reception of the water, and flanges C, for securing to a plain rim, l), having suitable arms, and connected to a shaft.

lstantially asl specilied.

'lhe buckets A aremade of metal, preferably by v The faces of the burkets range nearly radially, and are calculated -to receive the water at their bottoms,

and at the bottoni of the wheel, (which revolves in a vertical plane,) from a direction parallel with the said plane, and deflect-it upward to some' extent, and then outward, giving it a spiral course, whereby a greater' percentage of force is received from the water than when the faces of the buckets are made iiat. lhe Water is also prevented from reacting against the jet, and also vfrom clogging the wheel.

A further advantage is also gained, of discharging the water away from the shaft and pulley, which are on the opposite side, thereby saving the expense of a bulkhead to keep the belt dry; and a still further advantage -is, that in many cases, when the-head is Very high, the escaping water will be thrown so high as to be available for running directly into the batteries, for use there, without the employment of elevating-apparatus.

The buckets are secured to .the rim by bolts, and these mayhave slotted holes in the rim, so as to pormit adjusting buckets on the wheel with great exactness.

vHaving thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is-

l. The buckets A, provided with the spiral concave facesB, and combined with the rim,l substantially as speciiied.

2. The buckets, having' faces formed as described, provided' with flanges O, and secured to the rim, sub- J. G. FREDENBURR. W.v v. ANDREWS.
