MORGAN 59 IRRIGATION PUMP Filed May 2, 1938 2 Sheets-Sheet 2 ATTORNEYS Patented Sept. 24, 1940 STATES PATENT OFFICE 1 Claim.

This invention relates to irrigation pumps and has for the primary object the provision of a device of this character which may be readily set up in an irrigation ditch to separate different elevations through which the ditch extends and which will efliciently elevate water from a low level to a higher level with the water checked from returning from the higher level to the low level when the device is in operation or standing idle.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings,. in which- Figure 1 is a vertical sectional view illustrating an irrigation pumpconstructed in accordance with my invention and taken on the line Il of Figure 2.

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

Figure 3 is a sectional view taken on line 33 of Figure 1.

Figure 4 is a transverse sectional view showin the discharge mouth of the pump.

Figure 5 is a perspective view illustrating an impeller forming a part of the pump.

Figure 6 is a fragmentary vertical sectional view showing means for directing water to a bearing of the pump for lubricating purposes.

Referring in detail to the drawings, the numeral l indicates a sluice to occupy a position in an irrigation ditch and carries a partition or gate 2 separating the sluice and providing in said sluice a low water side A and a high water side B. The low water side A is at an elevation lower than the high water side. The sluice 1 has vertical uprights 3 for supporting the gate or partition 2. The gate or partition is further supported by braces 4 fastened onto a vertically arranged post 5. Mounted on one of the braces is an upper bearing 6 for supporting a vertically arranged pump shaft 1. A pump housing 8 is mounted on the bottom of the sluice adjacent the gate or partition 2 on the low water side and has a discharge mouth 9 extending through an opening formed in the gate or partition and on which is mounted a flap valve ll adapted to close the pump housing to the high water side B when the pump is inoperative. The shaft 1 extends into the housing 8 and is arranged eccentrically thereof. Secured on the shaft I within the pump housing is an impeller l2 of the rotary type and adapted to take water in axially thereof and to expel said water peripherally by centrifugal action. The top and bottom of the housing 8 have water inlets I3 for directing water from the low water side A into the pump housing axially of the impeller so that the water thrown out by the impeller during the rotation thereof will be against the walls of said housing and be forced toescape therefrom by the mouth 9 into the high water side B of the sluice consequently raising the water in said side B to a higher elevation than the level of the water in the side A. The water inlets I3 of the pump housing are in the form of cylindrical housings l receiving water through the sides thereof and directing said water axially of the impeller. Seal elements I6 are arranged between the top and bottom walls of the pump housing 8 and the impeller. A partition I! is arranged between one of the side walls of the pump housing adjacent the mouth 9 and the periphery of the impeller to prevent water from returning into the pump housing during the rotation of the impeller from the mouth side of the pump housing.

The impeller consists of a plate 18 having a hub l9 secured on the shaft 1. The plate l8 has angularly related faces 20 on which are mounted blades 2| disposed at an angle to the axis of rotation of the impeller. Ring-like plates 22 are secured on the upper and lower edges of the blades 2|.

The pump shaft 1 is connected to a power source in any well known manner so as to rotate the impeller in the direction indicated by the arrows in Figure 3. The water received axially of the impeller is forced out under pressure in the pump housing and escapes therefrom by way of the mouth 9. The water being thrown out by centrifugal action from the blades creates a suction to pull water into the impeller axially thereof from the water inlet. The force of the water escaping from the mouth 9 of the pump housing opens the check I I, the latter remaining open as long as the pump is in operation. However, when the pump is inoperative, the check I l gravitates to close the mouth and prevent water from the side B from returning to the side A. The housing [5 supports a bearing 22' for the shaft 1 and this bearing is fed water by way of a pipe 23. The pipe 23 receives water from the side B by extending through an opening in the gate 2.

A device of the character described can be easily and quickly set up in an irrigation ditch and will efiiciently elevate water from one level 5 plates mounted on the angularly related faces and extending substantially therefrom, ring like plates connecting the upper and lower edges of the said first-mentioned plates, compartments formed on the said housing and having openings to permit the ingress of the Water axially of the said plates, and means to rotate the said shaft.
