WELL MECHANISM.

T 0 all 'whom t may concern: i

Be it known that we, MAHLON E. LAfYNE UnitedStates, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain newand useful Improvements in Well Mechanism, of which the following is a specification.

The invention relates to well mechanism and particularly to means wherebypthe sec-- .shaft and its oil casing in shipping and'han ,dlingn The ordinary centrifugal pump mechanism comprises the pump which. is usually submerged in the water, a well casing lining the bore of the well and .power transmission and discharge apparatus extending to the surface of the ground. This apparatus comprises a discharge casing concentrically arranged with respect to'the well casing, a shaft or oil casing inside the dis# charge casing, and a drive shaft inside the shaft or oil casing and extending from the pump runners to the surface of the ground `Where it is connected with suitable driving i means so that even under the most unfavor-qmechanism. As the pump may be located at a distance ofl from 50 feet to several hunf dred feet below the surface ofthe ground,:

the various casings land the shafting are made in relatively short sections for convenience in handling and shipping and these sections are assembled' in the field,`secti'0n after section being added las the' pump is lowered from the surface ofthe ground.

Heretofore it has been the `practice to ship the sections of casing and shafting in long boxes the lengths being greased to protectthe-m during transit and'beforeinstallation This method of procedureis objectionable for several reasons.4 The boxes containing the apparatus are often exposed tothe' weather and the contents becomes wety andv rusty before it is installed. The parts are ordinarily greased inorder to protect them and when these 'parts are installed they are transporting the shafting lin boxes is apt to and SAMUEL N. HALmboth citizens of then shaft and shaft casing sections sop-that tene4 i sion can be applied to such parts thusservf,

thermore, the shock or vibration incidentto method of storageftransportation and han-v dling which will avoid thefforegoing objections, and, briefly stated, consists in :utilizing each discharge casing section as a Stor#v age or shipping' containerl for the corresponding section of shafting and shaft cas# ing. This -is accomplished byproviding ca-ps for the discharge casing sections which` not only form closures protecting the fcon-v tents of the casing but also `assist'inholding the shaft 'and shaft casingsectionlsecurelyv inposition inside the 'discharge casing. In

its preferred form atleast one of th'evcaps provide with screw engaging means; for the ing to hold these parts 'perfectly' straight,r

' so that there is no ldistortion during transp portation or handling. The caps employed may .be `either {screw threaded to lthe cou-` plings at the e'nd of the discharge casing lor may be clamped tightly Iin position by other able conditions as to 'exposure' andv moisture the contents of the container are kept-perf' fectly cleanand-.diy -When the apparatus is installedyitvcan'be elevated to a verticali `*position before taking off thevcaps and vca n Y thenbe assembled from7 this position so that .neither the 'shaft section nor the `shaft casing section'y comesfin co'ntactfv with the ground' andas -a result these parts are not f exposed to the dirt or sand at the time .of installation.` ACertain embodiments of-lthe invention are illustrated'in the accompanying drawings,l wherein-v Figure l is allongitudinal section through one form of thefcontainer with the parts in position therein. Fig.l 2 is a section showing the apparatus `of Fig. 1 suspended for installation and partially disassembled. Fig. 3 is a section similar to that of `Fig.-2but withl theparts still `further disassembled.

ReferringI first to thetconstructioii :is actu-y ally installed in the Well, this is shown in Fig. 4. whereinY 11 4lare the discharefc. c:is.

ing sections provided at their ends with the couplings 2 and 3; 11 4 11 are the shaft casing sections which serve to protect theAv shaftv and carry the bearings for supporting the shaft; 5 5 5 are' shaft sectionsse'- cured together by the coupling G 6; and 7 7 are bearings'for the shaft: The bearings are supported-by means ot tle' spiders' 8 8 integral with the couplings 2 and 3 and" carrying the sleeves 9 9 which are" integral with the spider. ln* order to prevent the bearings turningwith respect l 9 r9 the'split taperin'gf'bu'shi-nb 1010 may be'employed which l"-refforceddown-into position and heldf by' mea-ns and? of the opposing ends ofthe'v shaftfcasiiig'sections just l above.

The means 'whereby thedischia-rge casing 1 is utilized as'y container for the shaft cas' ing. and shaft Willl now be clear on 'refer'` encel to Fig.- 1,l which shows' these parts' in A pai-r of closureE conditionil for shipment; caps 1l and 12 are' employed,I such caps beingj preferably made of rounded'shape -andi Y being provided vWith- 'shou'lde'rs'l for abut.-

The inner end oftlie sh'aite'tensioii islthreadefl to the interior of the sha-ift casing 4 at 18 and to the' shaft coupling 6 at19 so thaton tigilninth nut v17 thefshalit" and shaftl casing' sections ligands areplaced-unclcrte1il sion-thus"insuringv that these parte Will :ot

Fig; 2 'illustrates-fthe- Vmethod of handeling the casingsfat the4 peint of installatie gan'dithej nut* 15 un' revv the sie eyes- The nut 1li remore`d-ai'ter' which? theca a 1-1 is" i i larger Well casing altho such construction able lifting device (not shown). rlhis permits the parts at the lower end of the case to drop down to the position indicatec after which the nut 17 and cap 12 are removed and the extension shaft 16 unscreWed.

.The removal. of the extension shaft 16 permits the shaft section 5 to move down to the position illustrated in Fig. The parts arev non1 in a convenient position tor coupling to the corresponding sections which have' already been placed in the well, the shaft and shaft casing being coupled to corresponding sections beneath and the coupling?) being coupled to the coupling on the discharge case section lying belovr.

ln rthis Way the various casings and sha-ft sections may be transported to the point of use and kept perfectly dry and clean during transportation and maintained against injury kunder the lroughest treatment. Furtherniore,` the arrangement permits of a very rapid and easy installation Without exposing any of theparts to contact with: the ground, sorthat theshaifting and bear* ings are assembled in a clean condition and.

Without the sand and grit which is ordi-fy narily'picked up during the installation operation.

The type of coupling` 2 not only co-operHV ates most advantageously with the closure caps tomalre a satisfactory container but also has other advantages as av part of' a pump discharge casing. rEhese couplings are secured to the pipe 1 by means of the usual tapered screnT connection 23 (Fig. L1) after Which they are held against unseren'- ing by means 'ofthe rivets Q4- or othersuit able means. The other end of the coupling is machined straight,L (not (tapered) andv screw threaded as vindicated clear to vthe machined shoulders. linl this Way the lengt-h Bi (Fig. f1) of the discharge casing section is made exact and deiinite so that. when assembled the discharge casing may be made to correspond to the length ot the shaft casing` and shaft, thus eliminating the necesi-5itiT o'' cutting any of thesections to .fit in the field such as hasheretotore been necessary Where ordinary threaded pipe couplings have been usedV for securing together the sections oi the discharge casing. Such couplings always screw together a more orr less indefinite amount when brought together to a tight position so `that the oier-all length of the casing can never be definitely deteri'ninerl until theparts are assembled The construeu tion is also advantageous as compared with flanged couplings since flanged' couplings oc cupy more space laterally thus requiring a be' made" definite as' to over-'all length; beft 'seenfthatthe present coupling- 'cti-"on occupies no; more space laterally y i ila-ryA sore-W'-coupling sfle'ev'efandl at'thesaeae'tnee prcmdeeror giving a fixed` l lO and definite length to the casing when assembled in the field.

Fig. 5 illustrates a modified form of cap construction, such modified form being primarily duc to screw threading the

caps

27 and 28 in place instead of having such caps merely fit over the couplings 2 and 3 as in the construction of Fig. l. The upper cap 27 is provided with an extension 29 which is threaded at 30 to the shaft casing 31 and atl 32 to the sleeve 83. At the other end of the casing l the cap is merely screw threaded to the coupling 8, the shaft casing being held by the spider 34 which engages the bearing 35 andthe shaft, being held by the nut 3G. This type of construction is somewhat more expensive than that of F ig. l bnt has the advantage of git/*ing a tight connection be.- tweenghe caps and the couplings 2 and '3 without the necessity of using gaskets, and the heads not being perforated, are less accessible to moisture and give a smoother outer surface so that the casing may be more readily moved around upon their ends without catching than the construction of Fig. l wherein the nuts are employed for placing the parts under tension. f

Fig. 6 illustrates a modification which may be employed at the lower end of the construction of Fig. 5 in those cases in which the spiders 3ft of F ig. 5 are not used. When these spiders are not used it is necessary to provide other means for supporting the end of the shaft casing and this is accomplished by the use of the sleeve 37 which is screw threaded to the bearing 35, the cap 3S being perforated to provide forthe passage of the sleeve. A second sleeve 39 with a closed end l0 fits into sleeve 37 and screws overthe end of the shaft section 41. Other modifications of the broad idea will'be readily apparent v to those skilled in the art.
