UNITED STATES moan PATENT DFFiCE 2 Claims.

My invention relates to improvements in pumping mechanisms, and refers particularly to a pumping mechanism adapted for deep water well operations.

5 The present invention covers improvements upon the invention shown, described and claimed in the application for patent filed by me on October 28, 1935, Serial No. 47,194.

The aim or purpose of this invention is to insure a more useful, practical and efficient pumping mechanism with the same general objects in view disclosed in said application.

One of the main objects of my invention is the provision of a lateral adjustment mechanism which will allow the adjustment of the impeller shaft, while said shaft is in motion, to raise or lower the impellers with reference to the seat for such impellers to allow dirt, sand, gravel or other foreign matter to be discharged before the flow of pure water and thus prevent injury to the impellers and contiguous parts of the pump mechanism.

Another object of my invention is the provision of a lateral adjustment mechanism having means for raising and lowering the shaft carrying the impellers without stopping the pump or interference with the general operation of the pump while pump is operating, thus saving a great amount of time, labor and money usually caused by this operation.

Another object of my invention is the provision of a pumping mechanism which by reason of its ease of adjustment of the impeller shaft while it is in motion will save much wear and tear upon the impellers and associated parts and thereby impart durability and long life "to the working parts of the pump mechanism. Another object of my invention is the provision of a pumping mechanism of the character stated 40 which'will provide efllcient lubrication or all working parts under all conditions and which mechanism in every respect will prove practical,

desirable and emcient.

Another object of my invention is the provision of 'a full floating lateral adjusting mechanism of character stated which will provide eiilcient cooling of the thrust bearing carrying the pump shafton account of said thrust bearing being above the heat of the electric motor and which provides more air space around thrust bearing.

Another object of my invention is the provision of a full floating lateral adjusting mechanism,

that will indicate the amount of wear on the imnism stated.

for the face of the impeller thereby preventing water from by-Passing or short-circuiting be- I tween the face of the impellers and their seats. 10

Another object of my invention is the provision of a lateral adjusting mechanism which contains the main thrust bearing of the pump or impeller J shaft independent of the electric motor which relieves all hydraulic thrust and shaft weight of! 16 themctor, thereby making the motor more eflicient and giving longer life to both motor and pump thrust bearings. The pump shaft thrust bearing in my invention could fail and no damage would be done to the motorv due to said bearing so being independent of the motor.

With these objects in view my invention consists of a full floating lateral adjusting mechanism of the character and for the purposes stated embodying novel features of construction and as combination of parts, substantially'as described and claimed and as shown in the accompanying drawings, in which:

l5 being formed with an oil chamber l6 and being further provided with a seating or guiding portion l'l.

It will thus be noted that the housing or casing I of my pumping mechanism comprises the lower or base section, the intermediate or rotor section, and thetop section, and upon said top section is mounted the dome I8 through the medium of the hingeflil at one side, while opposite saidv hinge connection the dome is retainedin closed H position by means of the rod 20, and pin 2|,

passing through slot 22, said slot permitting the use ofa pin, or aflat key or wedge as, found most From this construction it will b noted that the dome surmounts the top section and is normally held in locked position by means of the rod 20 and the pin 2|, but may be readily raised or lowered when required by releasing pin 20, and with- I: l drawing pin 2|, which allows the cover to bev i opened or closed on its hinge 19.

Mounted in the cylinder, seat or guide portion ll is the inverted shell or cartridge-23 having on its outer upper edge screw threads 24 with which engage the screw threads 25 on the inner face of slots 21 in which fit thepins 28, andvupon its outer partingpartial'rotation to said ring and causing the pointer 32.

Fromthis construction it will be noted that the shell or cartridge is mounted for vertical movement inthe guide in the upper portion of ment of said shell or cartridge. 1

Passing entirely through the housing or casing is the rotary shaft 33 which has the upper threaded end 34 receiving anut 35-and locked in position for set adjustment by means of the key 36 and this nut rests upon the head or block 31, which rotor '40, and upon said shaft is secured the upper flange plate 4| carrying pins 42 which slide in openings 43 of the hub 44, of the fan 45.

It will be noted that plate 44 is keyed to sleeve 39, and transmits power therefrom to shaft 33, through pins 42, and plate 4|.

The fan 45 is thus located above the motor provided with the regulation valve 56 and to which leads the water cooling pipe 51 while the oil tank or feedelement 58 ismountedin proper relation" to feed the'oil through the valve mechanismto thoil feed pipes53 and 54.

I V The lubricating system of my pumping mechanism is of paramount importance as it insures :the lubricant being supplied in the proper quantity, the supply governed or regulated and the temperature of the lubricant being of the proper fluid condition'in all kinds of weather.

From; this construction it will be evident that the oil is properly fed to the ball bearings atthe upper end of the-rotary shaft, intermediate and contiguous to the fan and rotor. and to the lower portion of said shaft, which shaft passes. down through the bearing 59 throughout the entire length of the supply pipe. and at its lower end carries the duplicate or twin'impellers B0. and 60', as most, clearly shown:-:inFig..2.

Dumping mechanism will be 1 readily v understood rapid rotation to th'eshaft which carries theim pellers and that such impellers are capable of .being set and fixed initially in proper relation to the valve seats in the inlet memberor nozzle, and that such impellers by raising of the supporting shell or cartridge-will permit the dis.-,

charge of any foreign matter preceding the flow of clear water, and that the vertical adjustment can be. made to-any degree to take up wear upon the faces of the impellers to bring such faces in proper relation tothe facespf the seat rings to obtain the ,most efficient results.

It will be apparent that the placing of the fzm in the desired relation to the rotor will insure a draft of cool air to the rotor and other enclosed mechanism to keep the moving parts of said mechanism in a proper cooled condition.

It will also-be noted that my lubricating system ensures the supply of a proper amount of lubricant to the moving parts of my mechanism and that such lubricant under all conditions of weather will be supplied attlie desired tempera.- ture toinsure the most eificient results.

The open top of the casing'places the adjusting mechanism where it is in plain view and accessible for moving the shaft to adjust the impellers in their cases during the running of the pump and thus to perfectly regulate the fiow of water through the outlet of the casing, or to shut on the flow.

The adjusting mechanism for the line shaft and impellers is capable oi indicating the position of the impellers in the cases through the open top of the casing and the adjusting mechanism is only capable of moving the impeller the set space allowed in said impeller cases.
