Application led June 20, 1921. Serial Nog''i.' i, l

To all 'whom t may concern.' "f I Be it known that Lnwrs l-lANnY, a citizen of the Unitedtates, residing atfLos Angeles, in the county of Los Angeles and Stateof California, have invented newand useful Vimprovements in Pumps, of which the following is a specification; e

rIhis invention is a pump adapted lfor deep well pumpingand includingv a casingsunlr into the well and provided with a foot valve at the lower end' of the same. v QA rotatable rod extends through` thecasing and is1provided with impellers at spaced points for raising a column of liquid through the casing.

In order that they impellers, by their presence in the casing, will not decrease the cross sectional area of the casing which is open to the flow of the liquid, said casing at the impellers is increased in diameter, and as a consequence an equal volume of liquid may flow throughout the length of the casing in order to prevent back pressure.

The invention also contemplates the provision of means within the well casing for preventing whirling of the column of liquid due to the action of the impellers, and as a result the loss of head in the column of liquid is prevented.

The invention will be readily understood from the followingdescription of the accompanying drawings, in which:

Figure l is a vertical section through a well showing a pump constructed in accordance with the invention, in side elevation.

Fig. 2 is a detail section on the line 2-2 of Fig. 1. i

In the drawings 1 have shown a deep wheel bore at l, and said bore receives the well casing 2 which at its lower endl is provided with an inlet check valve 3. Rod t rotates within casing 2 and has impellers 5 fixed thereon so as to be rotated with kthe rod vithidn the casing Jfor elevating a column of C[The impellers 5 are so positioned upon rod 4 as to be opposite joints between sections of the casing 2, and the couplings for said casing sections are so arranged as toenlarge the cross sectional diameter of the well cas* ing and therebypermit a uniform flow of liquid through the casing irrespective of the space taken up by the impellers.v v

As an instance of this arrangement, the

ends` of adjacent sectionsof l'casing 2 are spaced from onefanother` with `n'npeller 5 positioned in,r said space, and' coupling sleeves i 6 and 7 are threaded ',.Qntothe ends of the respective casing sections;r Thesey coupling sleeves divergently taper away from their ends which are threaded onto casing sections,

and the adjacent ends of said ,coupling sleeves are threadedk asshown at` 8 infor-der `*that* they may bfefconnected to form ttli'e 'coupling for the'sectiofnsof thefcasingf.` l

"In practice, the couplingsleeve 6 is prefn l erably yelongated and kis adapted to receive impellersy 5 withinthe enlarged end of the casing, while coupling sleeves 7 lis relatively short so as to be connected to coupling sleeve 6 below impeller 5.

In order to prevent whirling of the column of liquid in the well casing, vanes 10 are radially vdisposed in the casing and are preferably carried by coupling sleeves 7. These vanes are radially disposed and form a bearingll forrod 4.

It will be noted that my improved construction contemplates the use of .a practically continuous impeller shaft throughout i the entire length of the pump or well tube and said shaft being accurately balanced, which permits operation at the lowest possible speed for the maintenance'o eiiiciency; and, in thisconnection it will be understood that slow speeds oit operation eliminate vibration and also the possibility of crystalization, and likewise eliminate overheating of the bearings in the pump head.

fIhe provision of an inlet check valve at the bottom of the pumpprevents water from n escaping downwardly through the bottom oi the well tube, maintains a water column within the well tube when the pump stops, thereby excluding air and preventingy deterioration of parts, and provides for atmospheric pressure on rsuction when the i water drops belowv the lower pump runner or impeller.

The enlargement of the well tube adjacent to the impellers permits the latter to be constructed with ample blade surface so as to render the action of lifting the water' vcomparatively easy, permits the installation of guidevanes in the well tube without materially obstructing theflow of water, kmaintains practically the same area throughout. the length of the well tube, and permits the water to pass'through the runners at the same velocity as through the Well tube sections that connect the enlarged portions. Further, the enlargements in the Well tubing permits the impellers to be made larger than the tubingand in the proper proportions for the imposed duties.

It Will be readily understood that minor changes in the size, form and construction of the various parts of my improved pump may be made and substituted for those herein shown and described Without departing from the spirit of my invention, thev scope of Which is set forth in the appended claims.

Various changes may be made Without de parting from the spirit of the invention as claimed.

1What is claimed is: i r

1. A pump comprising a casing formed of sections, a pair of ,coupling sleeves connecting the confronting ends of adjacent sections, one of said. sleeves exceeding in diameter that of thev sections and tapered in one direction from a point substantially mediallyof its ends, the other sleevebeing y relatively short and tapered from the first Sleeve to the adjacent section, a plurality of vanes disposed radially Within and formed integrally With the short sleeve, a bearing sustained axially within the sleeve by said vanes, a shaft journaled in the bearing, and an impeller fixed to the shaft and disposed Within the first sleeve.

2. A pump comprising a casing formed of sections, a pair of coupling sleeves connecting the confronting ends of adjacent sections, one of said sleeves being relatively long and the other relatively short, with the former arranged above the latter, a plurality of vanes disposed radially Withinthe` short sleeve, a bearing sustained yaxially Within the sleeve .by said vanes, a shaft journaled in the bearing, and an impeller fixed tothe shaftabove the yvaries and Within the long sleeve. f

In testimony whereof Ihave signed my name to this specification. y f
