ROTARY DEEP-WELL PUMP.

Speccation of Letters Patent.

Patented May 21, 1918 Application filed October 6, 1916.v Serial No. 124,141.

To all whom 'it may concern:

Be it known that I, MATTHEW T. CHAP- MAN, a, Citizen of the United States, and a resident of Aurora, in the county of Kanet and State of Illinois, have invented certain new and useful Improvements 1n Rotary Deep-Nell Pumps, of which the 'following' o elements of which are designed preferably to be located below the normal level of the water in the well. The leading object of this invention is to provide a new and irnproved form of connecting means for .the

several discl'iarge-pipes, each of which is made up of united sections, through which discharge-pipes the water is forced out ofl the well, and also an improved arrangement vwater discharge piping comprising two vertland construction of bearings and inter-bracing means for the rotary pump shaft and the several discharge-pipes. I accomplish this object by the means illustrated and hereinafter particularly described, although it will be understood that, except as specified in some of the claims, I do not intend to limit myself to the exact constructions. and arrangements shown. That which I believe to be new and desire to cover by this applica` tion is set forth in the claims.

20 indicates a base plate supported at the to the .base plate 20, as is best shown in said Fig. 10. Rising from the casing 23 are three standards 25-26-27 to which 1s connected a standard 28, upon the upper end of which is revolubly mounted a hub 29 about which is removably secured a pulley 30. The hub -29 has adjustably connected to it the upper end of a shaft 31, the adjustment of the shaft being secured through the medium of nuts 32 mounted by means of screw-threads upon the upper end of the shaft.

\,The standard 28 comprises a sleeve 33.

which is out of contact withthe shaft 31; the shaft 31 and the hub 29 being supported by means of anti-friction bearings supported by said sleeve. Speh anti-friction bearings able screw-threaded openin base plate 20, a bearing 51 or the shaft 31 f other suitablel fastening devices. I

comprise bearing-rings 34-35 supported by the standard 28 and other bearing-rings 36-37 mounted in a sleeve 38 depending ll'rom'thc hub 29 about the sleeve 33 and Within a sleeve'39 rising from the standard 28. The oppositely-disposed portionsof the bearing-rings in which the racew'ays for the balls 40 are cut are obliquely disposed whereby such bearings are adapted to take care of both the, downward pressure and the lateral pressure, as will be readily understood. An

oil cup 41 is provided at the upper end ofA the shaft communicatin with a central duct 42 which conducts oil rom thecup to the upper bearing.' Oil is also adapted to be conducted tothe bearin s by a pipe 43 lead ing from the lower' end of a suitable tank 44 by which oil may be fed to the sleeve 39,

the space between the sleeve 39l andthe sleeve 33 being substantially filled with oil if desired.

The pulley 30 inthe construction shown is ada ted to be driven by means of a belt 45 which in turn is driven from anysuitable of the discharge casing 23 so as to provide communication between the` said pipes and the water discharge casing. 50 indicates a casing about the shaft 31 secured by means of screw-threads at its upperl end ,in a suitthrpugh the being secured by means of screw-threads upon the protruding upper end of the shaft casing 50.

Pipes 46,47 and 48 are to be of a uniform length-they may be 16 or 20 feet in length, ,more or less,'-but must be of a uniformv length. Then the three pipes are screwed into plate 52 at their lower` ends. The upper end ofeach pipe has a separate iange 49 screwed to each; then they are placed into a" machine and machined true 4and centrally` vfor the `alinement of shaft 31; then the fiange 53 lis connected to said flanges.l

is Ibest shown 1n Fig. l, the intermediate bearings 55 are supported by the casing 50 being connected thereto by means of screw- I threads. Each of the bearings 55 (see Fig.' 4) is provided with bosses 56 on its sides in 30 which are mounted by means of screwthreads short pins 57 upon the outer ends of which are mounted brackets 58 which are adapted to engage the pipes 46-47-48 for spacing such pipes in position relative to As is shown in Fig. 5, when more than one bearing 55 is employed between the 'adjacent bearings 54, a second length of casing 50 is secured b means of screw-threads to the lower end o the upper most one of such intermediate bearings 55, depending downward therefromv to the next bearing 55 for properly supporting it in po- `sition. As is bestshown in Figs. 1 and'5,

the lowermost 'one of the intermediate bear- 95 ings'55 for each length of the pipes 46, 47 and 48 has depending Afrom it a small pipe 59 in lieu' of a casing 50 surrounding the ower end tothe bearing 54 immediately below, vas shown in Figs. 1 and 3.

The` lowerinost bearing 54 for the shaft. 31 just above the pumping means down in the well 'is secured by means of a short threaded sleeve 60 to the u per end vof a sleeve 61 cast as a portion oi) a member 62 that is provided with three separate conduits 62a as clearly shown in Fig. 7 by which the water is carried from the pump casing 63 to the water discharge pipes 46,47 and 110 -in position by webs 68 centrally ofa casing 120 member 69 immediately below the ypump casing 63. `The uppermost cap plate 64 comprises a sleeve 70 in alinement with the sleeve 61. The sleeves 61 and 70 are provided with packing means 71-72, respec 125 tively, between which is mounted a coiled spring 73, metal plates 74-75 being interposed between the ends of the spring and the packing means. A recess 76 is provided near the lower end ofthe sleeve A61, whichrecessis connected by nieans of a pipe 77 with a tank 78 adapted to contain clean water. to the recess 76 serving to assist the spring 73 in holding the packing tight within the sleeves and serving to keep such packing wet 'so as to be serviceable for excluding the water being pumped from the bearing 54 immediately above the sleeve 61. Should the supply of water through the pipe 77 fail at any time, clean water from the supply being pumped may be furnished through a short pipe or nipple 79 that is located in one of the conduits 62, such nipple being clearly shown by the breaking away in Fig. 6 of a part of the wall of that conduit. This nipple communicates with the recess 7G, the entrance of water to the nipple being through a screen or iilter 80 carried at the upper portion of such nipple. Below such screen or lilter is provided a downwardly-opening valve 79a which is normally kept closed by the pressure of the water in the supply pipe 77 so that the clean water supplied to the recess 7 6 from the tank 78 will not be allowed to escape, but which Valve will open when the supply from such tti-spk fails and'admit water trom the stream being forced up through such conduitn-such water, however, being cleared or" sand, as

will be understood, on account of passing through the screen or filter 80.

l/Vithin the lower end of the casing G9 is mounted a shell 81 which is held in position by means of an outwardlyextending'flange 82 which extends between the casing 69 and the downwardly-extending casing 83, to the lower end of which the water suction pipe va double-leaved 'valve 86 which is in the the bar 85.

form of a flexible diaphragm of any suitable type provided with plates 87 fixed thereto tor holding it in position. The diaphragm is held in position by an inverted U-housing 88 which is held in position by means of suitable bolts 80 passing-through The sides ot the housing 88 are provided with suitable openings 90, and at its center the bar provided with an opening 91 adapted to be closed by a.V valve 92 which is held yieldiagly in closing position by means of a spring 03. the lower end of which is supported by a cross-bar 94 adjustably 'ield in position relative to the cross-bar 85 by means of screw-threaded pins 05. its best shown in 11, the pipe 24 has interposed in it a short section of pipe 06 of a larger size lmving small pipes QT leading downivard troni vlts lowermost portion, such pipes 97 opening into a small pipe 98 provided with a Valve 39, this arrangement being or the purpose of clearing sand from the water as hereinafter described.

Water from the tank 78 is thus fed.

In Fig. 13 which shows a modification ot the structure shown in Fig. 4, corresponding parts are indicated by the same reference characters, but with the addition of an exvwhich surround the water discharge pipes,

being provided with set screws 101 by which they are adjustable relative to the pipes. By the constructions shown in Figs. 4 and 13, the pump shaft is adapted to be adjusted relative to the water discharge pipes to secure proper alinement of such shaft.

In Figs.` 14 and 15, which show another modication, corresponding parts are indicated by the same reference characters but with the addition of an exponent b In this construction two water discharge pipes 102 and 103 are used in lieu of the threepipe construction of theA remaining figures, the construction here shown employing the adjusting means such as that shown in Fig. 13 in lieu of the type shown in Fig. 4.

In Fig. 12 is shown a modied form of mechanism at the bottom of the pump casy ying 63, the members 104-105 supporting between them a plate 106 upon a cross-bar 107 of which is mounted a two-leaved valve 108 of any suitable type adapted to close downward to prevent the escape of water downward through the suction pipe 84"'. A spring-seated upwardly opening valve 109 is provided in communication with the casimg member 104 providing relief for the water above the valve 108 as hereinafter de- 'l scribed.

With the shaft 31 being driven by means of the pulley 30, or in any other suitable manner, the runners 65 arerotated, serving to cause the water to rise through the suction pipe 84 past the valve 86 whence it is forced upward through the water discharge pipes 40,47 and 48 and discharged through the discharge head 23. A suitable supply of clean water is supplied through the pipe 77 from the tank 78 to the packing means 71 and 72, serving to prevent the water being pumped from passing upward about the shaft to the bearing 54 immediately above the runners. At the same time a suitable supply of oil is fed yto the'anti-friction bearings located within the pulley 30, such supply of oil coming from the cup 41 and the tank 44. Oil is delivered from the tank .44 also to the upper end of the bearing 51 through a pipe 110 branching from the pipe 43. Any excess of oil from the cup 41 flowing past the bearings within the pulley 30, together with such oil as is admitted to the 'pipe from the tank 44, passes downward i 51 through the easiiigO to the bearing 55 immediately below the bearing 51. The oil passing through the 4lowe'rmos't bearing 55 for any length'of pipes 46, 47 and 49 is conducted by the pipe 59.,to the bearing 54 immediately below. The oil is thus`-con ducted from the cup 41 and the tank 44 downward by steps through the various bearings and through vvarious lngths'ofv easings 50 and 59 to the bearing 54 immedi- -ately above the pump runners.

The water whichis delivered throu h the discharge -pipe 24 -at or near the sur ace is delivered into the enlarged pipesection 96. By reason of the enlarged cross-section of the pipe 96, the water is adapted to flow valve'at thebottom of the pump casing, I

am enabled to retain in the pump casing such an amount of wateras `may be necessary for starting the pump without priming from any other source. In order to Aprevent injury to the pump Casing by reason of the back pressure of the water upon the sudden stopping of the pumping operation when a check-valve is used, I haveprovided vthe downwardly opening relief valve 92 which is adapted to open automatically when the pressure above the valve exceeds the pressure below the valve by a certain predetermined margin.

The use of a relief-valve such as that shown in Fig. 6 serves also as a means for the escape of sand from the pump casing.

In many cases in newly bored wells a very high percentage of sand is pumped with the water for a considerable time, sometimes as high as thirty or forty per cent.

Upon the stoppage of a pump operating in a well ot' this type and provided with a foot-valve, if no meansrwere provided for the escape ofthe sand, the entire pump cas.-

ving above the Valve and a considerable portion .of the lower end of thc water, discharge pipe or pipes would be entirely filled with the sand which would settle from the water retained in the pump when brought to a stop, making it out of the question to start the pump again into operation., By the use of such a valve as that shown in Figs. 6 and S, the immense quantity of sand contained in the water is cleared from the casing leaving the valve 86 free to have its normal operation. This is accomplished by adjusting the` springl 93 oF the v alvc to sup- 'denly stopped or slowed down,`the bacioward pressure of the Water .upon the valve $6 is relieved sufficiently by the .openinfgoff' I'OIII juring the parts. If the spring f93 were set port any desired height ffwater abovethe' valve, this being effected through the' adjustment of the bar 94 along the screwthreaded pins 95. When the pump is sudthe valve 92 so as to prevent the water bursting the pump casings or otherwise i'nto4 support 20 feet of water, for examp1e,'in

a well 150 feet deep, then the valve 92 would be held open until the water in lthe upper 130 feet of the pipes 4'6-47-48 flowed at a fairly slow rate through the opening 91.

line of piping above the valve and substantially all of the,f sand would be washed out of the pump c sing and the discharge pipes long before tijd' water had reached the predetermined /l'evel at which the spring 93 l would act to close the Valve. Accordin ly when thevalve 92 finally closes it retains within the pump casing the desired column of clear water substantially free-of sand or other/sediment.. By reason of thi'sconstruction, when pumping has been carried on l)for some little time so as to carry the leve of the water Vin the well below the runners, when the pump is stopped temporarily for any reason a' quantity of water is'retained of a plurality of lines of sectional discharge piping, means for connecting's'aid lines of piping together at the section joints, a shaft,
