TURBINE PUMP 7 Victor J. Domer, Okeechobee, Fla. Z w 1 Application June 7, 1950, Serial No. 166,633

4 Claims. (01. 103-90) The present invention relates to new and useful improvements in pumps and more particularly to a turbine pump for' use in pumping water from wells.

An important object of the invention is to provide a turbine pump including a rotary shaft having a plurality of impellers at suitably spaced apart intervals and providing a novel bearing construction for centering-the shaft in a well casing.

Another object of the invention is to provide novel means for locking the bearing against rotation in the well casing.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which.

Figure 1 is a vertical sectional view of the assembled pump;

Figure 2 is an enlarged fragmentary vertical sectional view taken substantially on the line 2-2 of Figure 1, and;

Figures 3 and 4 are transverse sectional views taken respectively on the lines 3-3 and 44 of Figure 2.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of this invention the numeral 5 designates a casing in which a rotary shaft 6 is positioned, the casing having a water outlet head I attached to its upper end and formed in its side with outlet openings 8. The upper end of shaft '6 is journaled in a bearing 9 at the top of the head 1 and a pulley I is attached to the upper end of the shaft and is driven by a belt I I from a motor or other suitable power source I2.

A plurality of impellers I 3 are secured to shaft 6 by set screws It for lifting water entering the bottom of the casing to the head I and discharged through the openings 8.

A plurality of bearings designated generally at I are positioned in the casing between the impellers I3 and a collar I6 secured to the shaft above each of the bearings by set screws IT.

The bearings I5 comprise a rubber bearing sleeve I8 enclosed in a metal sleeve I9 and from which a plurality of centering fins project radially for. engaging 2 the casing and the bearing in the casing. I

The bearing is locked against rotation in, the casing by a locking fin 2| swingably mounted on a vertical pin 22 secured in upper and lower eyes 23 and 2t and one side of metal sleeve I9, the fin 2| beingswingable circumferentially of the casing 5 into wedgingengagement therewith. A coil spring 25 is positionedon pin 22 with one; end 326 of the spring bearing against. the metal sleeve"!!! of the bearing and the other end 21 of the spring bearing against one side of locking fin 2| to force the latter into wedging locking engagement with the inner surface of the casing.

In the operation of the device the shaft 8 is rotated by the motor I2 and the impellers I3 are thus driven to lift the water in the casing to the discharge head I.

The bearings I5 are positioned on the shaft immediately adjacent the impellers to center the impellers in the casing and to prevent vibration of the shaft.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the sprit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a turbine pump, the combination with a well casing having a rotary shaft therein with an impeller secured to the shaft within the casing, of a bearing in the casing in which the shaft is journaled including a rigid sleeve, rigid radial fins on the sleeve engaging the casing and centering the sleeve in the casing, a locking fin in the casing pivoted to the sleeve and swingable into wedging engagement with the casing to hold the sleeve and radial fins stationary in the casing, and a torsion spring mounted on the locking fin and reacting against said sleeve and locking fin to swing said locking fin into engagement with the casing.

2. In a turbine pump, the combination with a well casing having a rotary shaft therein with an impeller secured to the shaft within the easing, of a bearing in the casing in which the shaft centering is journaled including a rubber bearing sleeve, a rigid sleeve telescoped over the rubber sleeve, radial rigid members on the rigid sleeve engaging the casing and centering the sleeve in the casing, a locking member in the casing pivoted on the rigid sleeve and swingable about an axis parallel to the axis of the rigid sleeve into engagement with the casing to hold the rigid sleeve and rigid members stationary in the easing, and a torsion spring mounted on the locking member and reacting against the rigid sleeve and locking member to swing said locking member into engagement with said casing.

3. In a turbine pump, the combination with a well casing having a rotary shaft therein with an impeller secured to the shaft within the easing, of a bearing in the casing in which the shaft is journaled including a rigid sleeve, rigid radial fins on the sleeve engaging the casing and centering said sleeve in the casing, and a locking fin in the casing pivoted on the sleeve and swingable circumferentially of the easing into Wedging engagement with the casing to hold the sleeve andradial fins stationary in the casing.

4. In a turbine pump, the combination with a well casing having a rotary shaft therein with an impeller secured to the shaft within the easing, of a bearing in the casing in which the shaft is journaled including a rigid sleeve, rigid means fixed to and spaced around said sleeve and engaging the casing to center the sleeve in the casing, a fin extending parallel with the axis of the sleeve and pivoted thereto and swingable circumferentially of the easing into wedging engagement therewith to hold the sleeve and said rigid means stationary in the casing, and a torsion spring mounted on said fin and reacting against said sleeve and fin to swing said fin into engagement with the casing.
