ROTARY WATER-MOTO R.

SPECIFICATION formingpart of Letters Patent No. 534,916, dated February 26, 1895. Application filed February 9, 1894. Serial No. 499,635- (No model.)

To all whom it may concern:

Be it known that I, COLUMBUS K. ROGERS, a citizen of the United States, and a resident of Salem,in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Rotary Water-Motors, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in rotary water motors and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1, represents a side elevation of the improved rotary water motor. Fig. 2, represents a cross section on the line 2-2 shown in Fig.1; and Fig. 3, represents a vertical section on the line 3-3 shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

The invention consists of an inclosing shell composed of vertical sides A A between which is secured the peripheral casing or wheel chamber B having flanges b b bolted or otherwise secured to the interior of the sides A A in a water-tight manner.

In the side pieces A A are journaled the rotary wheel shafts G O to which are secured the Wheels D D provided with wings d d d d as shown. Above the wheel chamber B is located the pressure chamber E which is separated from the wheel chamber by a partition B which is of the form of two arcs of a circle arranged side by side upon a common base, which shape causes the partition to closely conform to the shape of the motor wheels. The partition B is provided with two series of ejector nipples that project downward at a tangent to the two wheels, the nipples of both series being inclined in the same direction so that the wheels will be rotated in the same direction. From the center of the partition B depends a divisionwall B that extends down to the motor shaft g and separates one motor wheel from the other and prevents any,

back pressure on the blades of the wheels and also prevents any water ejected against one of the motor Wheels striking the other. The chamber E is connected by means of a pipe e to any suitable source of water pressure.

The Water from the pressure chamber E is forced through a series of ejectors B B against the fans or wings d d of the wheels D D thus causing the latter and their shafts to be set in a rotary motion in the direction of arrows shown in Fig. 3.

F F are pinions secured to the respective shafts O O the teeth of which mesh in the teeth of a spur gear G secured to a motor shaft 9 journaled in the side pieces A A as shown in the drawings by which a rotary motion is imparted to said shaft from the wheels D D in the direction of the arrows shown in Figs. 1 and 3.

To the motor shaft 9 is secured a balance wheel H and a pulley h from which motion may be communicated by means of a cord or belt to the machine that is to be driven.

The rotary motion from the motor shaft g may of course be communicated to the machine to be driven by means of gears, sprocket wheels and chains or other well known devices without departing from the essence of my invention.

From the lower part of the casing B leads a discharge pipe B through which the water is allowed to escape from said casing after it has done its work in causing a rotary motion to be imparted to the motor wheels.

B is a division wall between the fan wheels D D so as to prevent the water ejected against one of the fan wheels from striking the other wheel as shown in Fig. 3.

Each shaft 0 C may have one or more motor wheels secured to the same shaft. In the drawings Fig. 2 I have shown two motor wheels secured to each shaft and I wish to state that I do not wish to confine myself to any num-' ber of motor wheels on each such shaft as I may use one or more according to the power desired to be conveyed.

By admitting water under pressure from the pipe e into the pressure chamber E the water is forced out in jets or streams through the ejectors B B against the motor wheels D D thereby causing the latter to be rotated in the direction of arrows shown and to convey a continuous rotary motion to the motor shaft g as fully shown and described.

The speed and power of the motor may easily be regulated by the adjustment of a stop cook or cutoff on the supply pipe 2, which is however not represented in the drawings.

ICO

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. In a water motor, the combination with the inclosing shell having journaled therein two motor wheels arranged in the same horizontal plane and geared to revolve together in the same direction, and a partition arranged over said wheels and dividing the shell into a pressure chamber and a wheel chamber, and provided with two series of ejector nipples projecting downward at a tangent to said wheels, and a division wall depending from said partition between said wheels to prevent back pressure on the motor wheels, substantially as described.

2. In a water motor, the combination with the inclosing shell having journaled therein two shafts O, O, carrying pinions F, F, and having rigidly mounted thereon motor wheels D,D, the motor shaft g jonrnaled in the shell and carrying the spur-gear G meshing with the pinions C, O, and operating to cause the motor wheels to rotate together in the same direction, the partition B arranged over said wheels and dividing the shell into a pressure chamber and a Wheel chamber and provided with two series of ejector nipples projecting downwardly at a tangent to said wheels, and a division wall depending from said partition between said wheels and extending to the shaft carrying the spur gear, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 24th day of January, A. D. 189*.

COLUMBUS K. ROGERS.
