Application November 7, 1933, Serial No. 696,932 3 Claims.v (Cl. 10.2 90) rThis invention relates to a pump of the type adapted to be lowered into a well casing or other restricted place and has for its principal object the provision of a pump of this character which will lift a maximum amount of duid with a minimum amount of power.

Another object of the invention is to so construct the pump that the line of flow of the fluid therethrough will follow gradual curved lines so lo that the water will not be required toA turn sharp ineiicient bends, and in which the rising water will follow a spiral or inclined path so that the pump will not be required to lift the water directly vertical.

A still further object is to provide a pump oi this character in which the surface of the irnpeller will be relieved from all back pressure or dead weight of the water column.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent fromthe following description.

in the following detailed description of the invention reference is had to the accompanying drawings which form a part hereof. Like numerals refer to like parts in all views of the drawings and throughout the description.

In the drawings:

Fig. 1 illustrates a Vertical section through a typical well casing illustrating the pump in place therein.

Fig. 2 is an enlarged section through the pumping portion of the device.

Fig. 3 is a bottom face view of the impeller.

Fig. 4 is a cross section through the pump housing taken on the line 4 4, Fig. 2.

Fig. 5 is a similar section taken on the line 5 5, Fig. 2.

Fig. 6 is a similar section taken on the line 6 6, Fig. 2, looking upwardly.

Fig. 7 is a diagrammatic, developed section through the deflecting portion of the pump.

1n the drawings, a typical well casing for receiving the pump is indicated at 10. The pump is supported therein on the lower extremity of a discharge pipe 11 of the necessary length. The Various lengths of the pump pipe 11 are connected by means of suitable bolt flanges 12. B-e- 50 tween the lengths of pipe are shaft bearing members 13, clamped in place by means of the flanges l2. These bearing members form journals for a vertical pump Shaft 14 which extends concentrically throughout the length of the pipe 11.

In the type of pump illustrated, a belt pulley 15 is secured on the shaft 14 .so that the latter 'l' ley to be iilled with oil througha suitable oiler 17. The oil from the oil reservoir ldconstantly feeds to suitable thrust bearings within the pulley 15, which in turn support the weight of the shaft 14. An outlet casting 18 supports the bearings in the pulley 15 from the pipe 11. The outlet casting is provided with an outlet 19 through which the water or other iiuidibeing pumped discharges.

A pump housing 2() is secured on the lower extremity of'the pipe 11 and a rotor housing 21 is secured upon the bottom of the pump housing 20. The rotor housing 21 is iianged as shown at 22 so that additional pump housings or additional intake pipe may be secured thereto. f

A semi-spherical rotor 23 is secured upon the bottom of the shaft 14 immediately below the pump housing 20 and within the rotor housing 21. The rotor 23 is formed with a convex back plate which when in place is directed downwardly, as shown in Fig. 2. Upon the convex surface of the back plate is a series of spiral, twisted vanes 24. The vanes 24 curve inwardly toward the axis in a spiral-like direction and simultaneously twist in a lateral direction. A line extending laterally across a vane adjacent the axis will be vertical, while adjacent the periphery a similarly placed line would be horizontal.

The inner face of the rotor housing 21 ts snugly to the outer edges of the vanes 24. The curvature of the Varies is such that their rst impact with the water, adjacent the axis, would act to direct the wat-er outwardly and their last impact with the water, adjacent the periphery, would act to direct the water upwardly.

A deflecting member 25 is formed in the pump housing 20 immediately above the rotor 23. It is desired to call particular attention to the deflecting portion as it forms one of the principal features of the improved pump. It might be cast integrally with the pump housing 20, as illustrated, or may be a separate section bolted or otherwise secured thereto. In it a series of peculiarly shaped passages 26 are formed. Three passages 26 have been found to be very satisfactory although, of course, the invention is not limited to this particular number of passages.

The passages 26 open at the bottom in narrow curved openings 27 extending abo-ut the periphery of the rotor, each having a length of approximately 120. The passages shorten in length as they pass upwardly and increase in width so as to open at the top deflecting portion 25 in round discharge openings 28. The passages 26 are inclined both in the direction of rotation of the rotor 23 and also inwardly toward the axis thereof so that they tend to incline in a general spiral-like direction. Above the deflecting portion 25 is a series of scoop-like shields 29, there being one shield placed on the forward' side of each of the discharge openings 28 so as to still further direct the discharging currents in a spiral direction as they emerge from vthe pump housing 20.

'Ihe deiiecting portion 25 serves a double purpose; rst, it prevents the weight or pressure of the water column in the pipe l1 from resting or pressing upon the upper face of the rotor 23; second, it causes the water to pass upwardly on inclined paths which can of course be accomplished with less power thanI by forcing the Water immediately upward. This provides a pump structure which will operate on less power and deliver more fluid than the usual types of pumps. 1 y

It is readily apparent that additional pumping elements can be secured along the pump shaft one below the other if desired so as to recreate a multi-'stage effect where high delivery against high pressures is. desired.

- While a specific forrn of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent 1. A pump comprising: a vertical shaft; a rotor mounted on said shaft, the lower face of said rotor being convex; spiral blades extending from said convex face; a rotor housing surrounding said rotor in close proximity to said blades; a

dispersion member positioned above said rotor and provided with a series of passages for receiving the discharge from said blades, said passages following substantially spiral lines through said dispersion member; a conical pump housing extending above said dispersion member; and deflecting flanges extending above the discharges of said passages into said pump housing so as to direct the discharging water on an inoline.

2. A pump comprising: a conical pump housing open at its top; a deecting member positioned in the bottom of said pump housing, there being passages extending through said deecting member, said passages having relatively long curvated openings in the bottom and substantially round openings at their top, the portions of the passages between the bottom and the top being inclined in a spiral; a rotor housing secured to said pump housing below said deflecting member; and a rotor mounted in said rotor housing so as to force uid into said passages.

3. A pump comprising: a conical pumphousing open at its top; a deecting member positioned in the bottom of said pump housing, there being passages extending through said deiiecting member, said passages havingfrelatively long curvated openings in the bottom and substantially round openings at their top, the portions of the passages between the bottom and. the top being inclined in a spiral; a shaft extending c'o-axially through said pump housing and through said deflecting member; a semi-spherical rotor member secured on said shaft within said rotor housing, said meinberbeingV positioned .Y
