Application led May 5, 1915.
T0 all whom z'z may' concern Be it known that I, ARTHUR L. MoR'roN, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented new and useful Improvements in Pumps, of which the following is a specification.
This invention relates to a deep well ump.
One of the objects of the present invention is to provide a simple, substantial, cheaply manufactured deep well pump, and particularly to provide a novel form of impeller and diffusion member which produces a considerable increase in efficiency.
Another object of the invention is to provide a simple form of casing or housing for each impeller and connected diffusion member which may be built up to permit application of additional units where the head is increased as conditions demand.
Further objects will hereinafter appear.
The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accom panying drawings, in which Figure l is a vertical, central section showing the installation of the pump. Fig. 2 is a plan view of the runner or impeller. Fig. 3 is a side elevation of same. Fig. 4: is a side elevation of the diusion ring. Fig. 5 is a horizontal section on line 5 5, Fig. 4:.
' Fig. 6 is a horizontal section on the line 6-6,

1ers, such as indicated at 7, said impellers being suitably secured upon the shaft so as to'turn in unison with same, and inten posed between each impeller is a diffusion ring, such as indicated at 8. The diffusion ring consists of a central bearing member 9, eXteriorly of which is mounted a ring 10, and interposed between the bearing member 9 and ring l0 vis a plurality of diffusion vanes ll. These vanes are convex or scooplike in shape; the lower end of each vane bemg straight and radially disposed, as indicated at 12 in Fig. 6. The remainder of the vane then gradually assumes a twisted shape, such as indicated at 13, in Figs. 4 and 5. The vanes thus shaped will take the water discharged in the direction of arrow a from the impeller mounted just below and reverse its direction.
The impeller running in the same direction as arrow a will impart a swirling action to the water which travels in the same direction. lower end of thediusion vane will lgradually be changed in direction and will nnally be reversed before discharging at the upper end of the diffusion vanes, as the water entering or striking the scoop-shaped vane will gradually turn in the direction of arrow b and finally discharge at the upper end inthe direction of arrow c. The swirling action of the water is thus destroyed and its direction reversed. The scoop-shape of This water entering the the vanes reverses the direction or flow of the water while thegradual twist provided in the vanes has a tendency to force the water inwardly toward the intake end of the neXt impeller. The water is admitted as near the center of the impeller as possible and skin friction with relation to the inner face of the casing is reduced to a minimum. 'ihe diffusion rings are in this instance placed on top of a pipe section, such as inupon the seat, the coupling thus forming a housing. The impeller, indicated at 7 is interposed between each diffusion ring and the pipe sections 5 form housings eXteriorly of the impellers.
Any suitable number of units may be added to or taken away as conditions warrant, as it is only necessary to add the desired number of impellers, together with the pipe sections and couplings required. The impellers shown in the present instance are provided with three blades, the outer edges of which are flanged, as indicated at l5. The lower intake of each blade is straight, as indicated at 16, while the upperl discharge end of each blade is considerably inclined, as indicated at 17. This permits the blade to receive the water discharged from the upper end of the diffusion vanes and thev water received will be forced up the blade surface, and as it strikes the inclined upper end it is thrown inwardly toward the shaft of the center of the casing. The flanged edge of each blade also has the same tendency. Skin friction on the interior of the casing isthus considerably reduced.
In operation, referring to Fig. l, it will be seen that the lowermost pipe section 5 serves as the suction or intake end of the pump. The water is here lifted by the lowermost impeller indicated at 7 and when discharged will immediately enter the lower ends of the diffusion vanes in the direction of arrow a. The vanes will then gradually change the direction or flow of the water and finally discharge it at the upper end in the direction of arrow c. The water will enter the second impeller indicated at 7 in a direction opposite to its revolution, which is in the direction of arrow a. An efficient action is thus produced, as the water flowing in a. direction opposite to the revolution of the impeller is more easily gripped and raised than would otherwise be the case.
The cycle of operation or flow of water from one unit to another is the same as described, the number of units depending upon the head required and other conditions. The upper twisted shape of the diffusion vanes, together with the. inclined or angular shape near the upper end of' each impeller, has a tendency to increase the efficiency of the pump, as the water is always discharged or thrown toward the center of the casing while passing from one unit to another, reducing skin friction with relation to the interior of the casing and at the same time delivering water at a point where it is more efficiently raised from one unit to another.
A pump constructed as here shown may be exceedingly cheaply manufactured as the exterior casing of the pump is constructed of nothing more or less than pipe fittings screwed one into the other. These sections when screwed one into the other also form seats and clamping members for the several diffusion rings, thereby eliminating any necessity of otherwise securing same, and the bearing members provided in each diffusion ring` at the same time serve as an alineiuent for the shaft and bearings for same.
The materials and finish of the several parts of the apparatus are such as the eXperience and udgnient of the manufacture may dictate.
I wish it understood that. various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that l do not wish to limit myself to the specific design and construction here shown.
Having thus described my invention, what l claim and desire to secure by Letters Patent isl.

et. In a pump of the character described, an impeller comprising a hub, a plurality of radially disposed, inclined blades on said hub, the intake end of each blade being straight and radial to the hub, and the discharge upper end inclining upwardly and outwardly, and a flange of gradually increasing height from the base to the top on the outer edge of each blade.
In a pump of the character described, an impeller comprising a hub and a plurality of radially disposed, inclined blades on said hub, the intake end of each blade being horizontally disposed with relation to a vertical line through the hub, and the discharge end of each blade being disposed at an upward obtuse angle with relation to thevertical line.

7. In a pump of the character described, means to check the outward whirling motion and peripheral friction of the water, consisting of fixed diusion vanes with horizontal radially disposed lower edges, said vanes gradually increasing in curvature upward around the axis, and terminating in an inward twist, and rotary impellers having radial straight edges, to which the water is delivered from the diffusion vanes in an opposite direction from its entrance to the vanes. c
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
