WATER-M OTO R.

SPECIFICATION forming part of Letters Patent No. 408,075, dated July 30, 1889.

Application filed April 6, 1889. Serial No. 306,193. (No model.)

To all whom it may concern.-

Be it known that I, HEZEKIAH BROWN, a citizen of the United States, residing at Brownsville, in the county of Chautauqua and State of Kansas, have invented certain new and useful Improvements in IVatenMotors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an apparatus for utilizing the force of currents and streams for'operating an undershot wheel fixed upon a floating frame or boat; and it consists of certain improvements in such a wheel, in combination with said float and adjustable wings, as hereinafter described, whereby the power so obtained can be used to actuate any suitable mechanism that maybe connected therewith.

Hy invention is illustrated in the accompanying drawings, in which Figure 1. is a plan. view; Fig. 2, a longitudinal section; Fig. 3, afront view, partly in section; and Fig. 4, a detail.

Referring to the drawings, A is a frame or float in which the wheel B is mounted.

The open head of the float, designed to face the current, is provided with wires or rods 0, arranged at suitable distances apart to prevent the entrance of logs or other obstructions to the wheel, and with a sliding gate D to shut off the current when it is desired to stop the wheel. The slot 25, through which the gate is passed, is cut on a bevel, so as to hold the gate in an inclined direction against the current, and whereby the gate is made adjustable at any height to regulate the speed of the wheel. The force of the current pressing against the gate will also aid in holding the gate at the desired position.

F F are current boards or sweeps hinged to the sides of the head of the float. The sides of the float at that point are beveled inwardly, as shown at a a, to permit the sweeps to swing inwardly across the front of thefloat. The sweeps are each provided with an attachment G, which are adapted to receive cords or ropes, by which the same can be held in any desired position by securing the ropes to the shore. As shown, these attachments G are made of wire bent into aloop g at their ends to receive the cord, rope, or chain; but

it is apparent, of course, that other forms of attachment may be adopted.

The sweeps can be brought together in front, or one sweep be placed across the current to stop the access of the same to the wheel.

The sweeps are also so hinged that they can be swung back against the sides of the float to let logs or other debris be carried by.

The wheel B consists of a double casing H H.

H is an inner water-tight cylinder formed by having its solid heads joined to the outer casing H at a distance inside the outer casing. Between the heads of the outer casing H and the heads of the inner casing spaces or chambers I I are formed at each end of the wheel.

L L are the floats of the wheel hinged to the outer casing H at m. They are flat, and when closed lie flat against the wheel. They are connected to rods P. The rods I, s'ecured at one end to the float, are passed through slots 0 in the outer casing H, and then into a chamber I, and at that end simply turned so as to engage with the wall of the chamber and to prevent them from falling out. It will be seen that these rods are free to move through the slots 0 when the floats fall, which the latter do by gravity as the wheel revolves.

R is a cover by which the top of the wheel is protected and water prevented from flowing onto the wheel when the same is sub merged or partly submerged.

Having thus described my invention, what I claim is The wheel 13, consisting of a double casing H H, the latter forming an inner air-tight cylinder, with chambers I at the ends of the wheel formed between the heads of the inner and outer casing and the floats, said outer casing provided with slots 0, the freelymoving rods 1, extending into said chambers and to which the floats are secured, 'in combination with a frame to support the same, substantially, as described.

In testimony whereof I affix my signature in presence of two witnesses.

HEZEKIAH BROWN. \kVitnesses:
