Be it known that I, J osnrn E. SAUNDERS,

a citizen of the United States of America,

g which the followinglisa specification.

My invention relates to improvements in centrifugal water lifting pumps, and the objects of my invention are: F irst-to provide a centrifugal water-lifting pump that will raise water by the centrifugal action of a rapidly rotating conical cylinder. Second.-to provide a pump that will raise water by centrifugal force and in which the discharging water isnsed to-develop power, which is applied to assist in operating the pump; and Thirdto providg a simple, inexpensive, durable and practicahrotary centrifugal pump that does not contain any incased rotatin or reciprocating parts, and that is especial i water for irrigation and other. purposes. I attain-these objects by the mechanism illustrated in the accompanying drawings, in which: i

Figure l is a plan view of the improved centrifugal water lift.. Fig. 2 is a vertical sectional view through the same. Fig. 3 is a bottom plan view of the supplemental power imparting water wheel. plan view of the rotatable conical casing. Fig. 5 isa plan view of the intake box. Fig. (i is a front view of the same; and Fig.

7 1s a side View of the adjustable water dividing blades.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings: the numeral 1 designates the water intake conduit of my centrifugal pump. This intake conduit may be a pipe or a box shaped intake. I preferably make it in the form of a Hat box shaped tube and provide it with an -outlet pipe portion. 2, which projects from the top of its opposite" end. This outlet pipe 2 of the inlet box 1 is provided with a hollow tubular central stem portion 3, upon which -a. hollow hub lis slidahly mounted, which supports a pair of water dividing blades 4. These blades are secured to or are formed on the opposite-sides, of the hollow hub 1t, and theiroutencnds extend loosely 'between ribs (3 formed on the insidgyof the out-let pipe 2 that form slideway spaces" for, them in the water intake box. These water dividy adapted to pump or rare Fig. 4 is a ing blades are arranged to extend diametriw cally across the outlet pipes orifice, and.

they are made to be moved slidably upward from the bottom of the intake box to a. number of inches above it, and they are adapted to prevent water. as it is drawnup into the conical water lifting tube, from swirling into a ring shaped column in the outle pipe portion of the intake box.

hand operating rod (3 is provided for lifting the water diriding blades. This rod is secured at one-end to the blades and extends up through the water box above the 'ater and is provided at its upper end with a handle portion (5. This rod may be secared to hold the blades in any desired adjusted position by any suitableineans, such as by a pin 6 that is adapted to rest on a cleat (3 and to be inserted in a row of holes (3 formed in the rod 6. The hollow tubula'r stem ii is secured to the bottom of the water-intake box and is arranged to form a gnide bearing for the lowerend of a vertica supported shaft 8 which extends loosely lrrough it and is jonrnaled any suitable journal box 6, which may be seecured to and snpported on any suitable foundation such asstnne or concrete founda tion or a wooden oframe or a timber. The upper end of this shaft. Sissnpported by a bar 8, secured to cross bars hot :1- wooden or metal frame 10.

A journal box 11 is secured to the bar 8 and the upper end of the vertical shaft 8 is rotatably journaled in the box 11. Upon this shaft 8 a vertically positioned conical casing 12 is mounted, which may be made of any suitable material such as galvanized iron or steel or sheet or cast. iron or other metal, and it is secured to the shaft by any suit able meanssuch as set screws 13,whieh are threaded through hub portions 14, which are formed on spider arms 15, that extend from and are secured to the inner peripheral wall of the conical casing. These spider arms 15 are preferably placedat the upper and lower portions of the conical casing. This conical casing is arranged with its apex or smallestdiameter portion at its lower end and this lower end portion is provided with a tubular inlet portion 17 which is arranged to exteudloosely over tlyeprojecting pipe outlet .secured in any suitable manner to the inte rior of the conical casing, and they are ..adapted to be placed at the lower end portion of it, preferably at its lowest portion, and they extend any predetermined distance along the interior of the casing. Thisconiwater discharging pipes 23. These dis-1 cal casing may be of any desired degree of taper and its larger top end'may be of any desiredlarger diameterrelative to its intake lower end, and it. may be of any desired length. I find in practice, however, that this casing may be given a taper 'suflicient to make its upper end several tunes the diameter of its lower end and lift Water in a strong stream when rotated at a high rate of speed, but this taper may be varied considerabl to suit higher or lower rotative speeds o the casing. The top of this casing is provided with a partial cover-like rim portion 21, which preferably'slopes upward in conical form and is arranged to leavean opening through its; top portion into the interior of the casing. The to peripheral edge of the casing isprovi ed at equidistant points throughout its circumference with,

charge pipes are arranged to discharge the water raised by the centrifugal movement in jets against a supplementary or auxiliary power imparting device, WhlCh is loosely mounted on the driving shaft 8 of the casing and assists in driving the driving shaft and its casing through'the medium of-the discharg-' ing water, as will be presently described. The upper end of the, casing'is surrounded by a stationary water receiving trough 24,

which is preferably circular and is substantially rectangular in 'cross section and is provided with a discharge pipe 25, whlch is arranged to lead the-water to any predetermined point away from the casing. The top edge of this trough is provided with an upwardly inclined rim portion 26, which is adapted to cover the telly portion of a supplementary power imparting wheel 27,

A which is driven by the discharging jets 6f water from the top of the casin as will be presently described' The vertical driving shaft 8 extends above the casing and upon it I mount-and secure to it by any suitable means a power driving wheel 28. This power driving wheel 28 is preferably a belt .driven sheave wheel, but ma be a sprocket chain wheel or a bevel gear, 1f desiredx The wheel 27 comprises aslightly dished or conical disk 29 and a ring 30, between which are secured a plurality of impact blades 31,

which are adapted to .be; engaged by the jets of water escaping through the pipes The wheel 27 is secured to a sleeve 32, which is loosely mounted upon the shaft 8, and may be provided with ordinary ball bearings if flange 33, which is connected with the disk 29 by a plurality of radiating brace rods 34. The ring 30 of thewheel 27 encircles the upper end of the cone- 12, so thatthe blades 31 and ring 30 lie within the trough 24. A

with the discharging jets of water, and they are preferably curved toward the discharging jets ofwater so that they will offer a right angled surface for the jets to strike against, as they move away from them. A suflicient interval is left between the bucket blades to allow the water after impinging against them to pass freely out from them into the trough.

The shaft driving wheel 28 and the power transmittingwheel 35 of the water wheel 27 are connected by belts 36 and 37 to similar power transmission wheels 38 and 39, which are mounted on a counter shaft 40, upon which a power driving wheel 41 is secured. This counter shaft is journaled in boxes 42, which are secured to parts of the frame. The wheel 41'is driven by a belt from any suitable source of rotating power, such as by a windmill or by horse power or by hand power or by steam, electric or other suitable power.

This speed, however may vary with the height of the lift or length and inclination of'the' sides of the casing. The high speed These bucket blades are arranged dlrectly opposite to and in alinement rotative movement of the casing rotates the .waterand throws it by centrifugal force around and up the inclined inner peripheral surface of the casing to its upper top rim portion, from which it is discharged in the form of jets through the discharge pipes 23 against the bucket blades 31 of the water wheel. This virciunferential row ofiiischargingjets has force enough to drive the water \rhccl rotativclv at a high rate of speed and with considerable power, which power is transmitted by its power wheel ill!(-)Il; !ll lhe belt. .37 to the sheave wheel 39 desired. The lower end of the sleeve has a on the counter shaft and assists the counter shaft to drive the casing. The water di 'iding vertically slidable blades t in the intake box prevent the water as it is drawn into the discharge tube 2 of the intake box from being swirled into a ring shaped body of water, which must naturally assume this form of a column under the centrifugal action of the casing and which would reduce the volume of infiowing water flowing from the intake box through its outlet ipe portion into the lower end (if the casing, which is also provided with water dividing blades for the purpose of forcing the water to rotate at the same speed as the casing. The verticallvsliding blades permit of a vertical positioning of these blades .relative to the speed of the casing to thoroughly break up any swirling action of the Water in the outlet pipe of the water ggnintqnre box.

My invention provides a simple, positive and thoroughly practical and inexpensive pump for lifting water in which the centrifugal force of the discharging water drives a wheel that adds a constant supply of power to its operations and decreases the amount of power required to operate it by the amount of power its discharging water jets develop in the water wheel which they drive.
