MOTOR ATTACHMENT'FOR' CENTRIFUGAL PUMPS.

SPECIFICATION forming part of Letters Patent No. 356,264, dated January 18, 1887,

Application filed June 29, 1886. Serial No. 206,613. No model.)

To aZZ whom it may concern-.-

Be it known that I, BARTON W. 'Scorr, of Logansport, in the county of Cass and State of Indiana, have invented a new and Improved Motor Attachment for Centrifugal Pumps, of which the following is a specification, reference. being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a vertical transverse section showing a centrifugal pump with my improved motor attachment applied. Fig. 2 is a detail sectional view of a centrifugal-pump wheel and the power-wheel, showing their relation to each other. Fig. 3 is a detail view showing the arrangement of the wheels and belts for transferring motion from the motorwheel to the pump-wheel; and Fig. 4 is a de-. tail perspective view of one of the floats or buckets of the motor-Wheel.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

In centrifugal pumps as ordinarily constructed the water, after being raised by the pump, is discharged with great velocity from the periphery of the wheel, and the force of the water so discharged is usually wasted.

The object of my invention is to utilize the power of the water issuing from the periphery of the centrifugal-pump wheel for assisting in the propulsion of the pump.

My invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

The centrifugal-pump wheel A is mounted in the casing B on the shaft 0, extending transversely through the casing and into the suction-pipe D. The suction-pipe D communicates with the center of the centrifugal wheel A, and is provided with an air-valve, a, through which a small quantity of air is introduced into the casing B along with the water.

Upon a sleeve, E, surroundingthe shaft 0, and extending through the wall of the casing B, a disk, F, is secured within the casing and in close proximity to the side of the centrifugal wheel A. The disk F carries a number of buckets, G, which project over the periphery of the centrifugal wheel A. Each float or bucket is provided with a series of chambers, b, as shown in Fig. 4, to insure the more effective action of the water on the buckets.

Upon thesleeve E, outside of the casing 13, is mounted a pulley, H, and above the shaft 0 is supported a counter-shaft, I, carrying a small pulley, J, which receives motion through a belt, K, from the pulley H. The countershaft I carries a large pulley, L, which drives the pulley M on the shaft 0 through themedium of the belt N.

The shaft 0 is provided with a driving-pulley, O, by which the centrifugal wheel A is set and continued in motion. When power is applied to the pulley O and water is discharged from the ends of the hollow arms of the centrifugal wheel A, it impinges on the buckets G and causes the wheel F to rotate, and the rotary motion of the wheel F is transferred to the shaft 0 through the mechanism already described, so that the force of the water issuing from the extremities of the arms of the centrifugal wheel A is utilized in assisting to drive the pump-wheelf In starting the pump a small amount of air is allowed to enter the air-valve a along with the water, so that the ler el of the water in the casing B is reduced to the line 0 below the motor-wheel, thus permitting the wheel to revolve in the casing without bringing its buckets into contact with the water at the bottom of the casing. After the pump is in motion the valve a is closed, as sufficient air will enter with the water to prevent the rise of the water above the line 0 in the casing. WVater discharged from the pump and wheel escapes from the casing through the lateral opening P at the bottom thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with the casing B, having the outlet P in its bottom, the inlet-pipeD, through which the water is drawn, and a bearing in the opposite side of the casing, of the horizontal shaft 0, a centrifugal wheel, A, fixed to said shaft and having a side opening communicating with the pipe .D, the disk F, having a sleeve, E, mounted inthe bearlarge pulley L, and the belt N, connecting it ing opposite pipe D, the shaft 0, passing with the small pulley M, substantially as set 10 through said sleeve and provided with the forth.
