PATENT OFFICE:

2 Claims.

The invention aims to provide a simple and inexpensive, well-balanced, eflicient and longlived rotary pump designed primarily for irrigation purposes but not restricted to this field of use.

With the foregoing in view, the invention re sides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a central longitudinal sectional view through a pump constructed in accordance with the invention'.

Figs. 2 and 3 are horizontal sectional views on lines 2-2 andv 3 3 of Fig. 1, respectively.

Fig. 4 is a perspective view of the lower section of the casing.

Fig. 5 is a perspective view of the rotor.

The pump casing C is provided with a cylindrical side wall 8, with a lower end wall 9 and with an upper end wall I0, said lower end wall 9 beingprovided with a liquid inlet li while said end wall I is formed with a liquid outlet l2, said inlet and outlet being centrally located and being suitably adapted for connection with pipes or couplings I3 and I4 respectively. The casing is preferably formed of upper and lower halves flanged and secured together by bolts I or connected with each other in some other adequate disk I 9 centrally secured to the lower end of said shaft, and a plurality of spirally directed vanes 20 secured to the lower side of said disk. The disk I9 is disposed about midway between the end walls 9 and I0 and its peripheral edge is spaced from the casing side wall 8. The vanes 20 extend to the edge of the disk I9 from the periphery of the liquid inlet I I and the curvature of these vanes radially deliversthe liquid from the rotor and of course also moves the liquid circumferentially. l

Helically pitched vanes 2l are secured to the cylindrical side wall 8 of the casing between the peripheryof the rotor and said side wall, said vanes 2l being so pitched as to elevate theliquid into the space between the disk I9 and the end wall I0. Fixedly mounted in this space, preferably by securing them to the end wall I0 and the extending from saidside wall to said outlet. I

(Cl. 10S-103) side Wall 8, are spirally pitched vanes 22 which direct the liquid to the outlet l2.

I preferably provide a web 23 extending dia.- metrically across the inlet II in a plane extendling longitudinally of the axis of'said inlet, for 5 the purpose of preventing whirling of the liquid during its passage through said inlet, thus allowing the spirally pitched vanes to more effectively act upon the liquid to centrifugally deliver it. 1o

The shaft i8 may, of course, be driven in any suitable way and when this shaft is rotated, the liquid is" centrifugally delivered by the rotor vanes 20 and is circumferentially moved also by these vanes. The circumferentially moving, i'al5 dially delivered liquid is elevated by the helically directed vanes 2l and this liquid is directed tothe outlet I2 by the spiral vanes 22. 'Ihe pump is well balanced, requires little power for its operation, is highly eiiicient, and long-lived.

While the details disclosed may be followed if desired, variations may of courseA be made within the scope of the invention as claimed.

vI claim:

1. A water pump comprising a cylindrical cas- 25 ing whose length is less than its diameter, said casing having one ilat end wall provided with a central relatively small inlet spanned by a flat web in a plane unidirectional with the casing axis, said casing having a second flat end wall provided with a central outlet of substantially `the same diameter as said inlet, a bearing secured centrally in said outlet, a rotor in said casing co-axial with the cylindrical side wall of said casing, said rotor comprising a central shaft ro- 3" tatably and non-slidably mounted in said bearing, a flat imperforate disk secured at its center to said shaft and situated substantially midway between said end walls, the peripheral edge of 40 said disk being spaced from said casing side wall, I

and spirally directed water-moving vanes secured to the side of said disk toward said one end wall, said vanes extending from said disk substantially to said one end wall and extending 5 from said inlet to said edge of said disk, helically directed water-moving vanes secured to said casing side wall around said rotor and extending from said one end wall substantially to the plane of said disk, and spirally directed water-moving vanes situated between said disk and said'second end wallfthese vanes being secured to said second end wall and to said side wall, extending from said second end wall toward said disk and 2. A water pump comprising a cylindrical casing -whose length is less than its diameter, said casing having one end wall provided with a central relatively small inlet, said casing having a second end wall provided with a central outlet of substantially the same diameter as said inlet, a bearing secured centrally in said outleta rotor in said casing coaxial with the cylindrical side wall of said casing, said rotor comprising a, central shaft rotatably and non-slidably mounted in said bearing, an imperiorate disk'secured at its4 center to said shaft and situated substantially midway between said end walls.- the peripheral edge of said disk being spaced from said casing side wall. and splrally directed water-moving vanes secured to the side oi said disk toward said one end wall, said vanes extending from said disk substantially to said one end wall and extending from said inlet tesaid edge of said disk, helically directed water-moving vanes secured to said casing side wall around said rotor and extending from said one end wall substantially to the plane of said disk. and spirally directed, water-moving vanes situated between said disk and said second end walll these vanes being secured. to said secl0 ond end wall and to said side wall, extending from said second end wall toward said disk and extending from said side wall to said outlet.
