wat

This invention relates to improvements l'in pumping apparatus and it consists of theV constructions, combinations and arrangements herein described and claimed.

One of the outstanding objects ofthe invention is to providev4 a pumping apparatus having'a stationary piston and a'movabl'e working barrel producing a combination yof particular merit when used in connection with a windmill, to which end the Working barrel is so connected'with the windmill that the pumping operations occur on the upstrokes of the. .latter rather than the down strokes; as is generally customary inapparatus of'this kind.

Another object of the invention 'is to enable the complete elimination of stuffing boxes, orpacking tubes in pumping yapparatus of this kind,` particular reliance being placed upon a peculiar arrangement ofv cup leathers yon the stationary piston for preventing the leakage of waterstherearoundj A further vobje-ct of the invention isV to make provision for the ready removal-of the. piston and its accessories from its stationary L llocation in the apparatus so thatvthe cup leathers can be renewed as may be `needed without completelydisorganizing the structure. 1

AV still further object of the'invention is to produce a unitary-pumping apparatus,' that is to say, an apparatus which is a unit within itselfrandas such can be transported and set up in a workingposition upon a suitable foundation. K Y

Other objects and advantages will appear in the following specification7 reference being had to the accompanying drawings, in which:

As previously Y'pointed out in `one of the foregoing statements vof the'objects ofthe inventiomjone ofthe purposes of theimproved ,pumping apparatus is to ease theoperation of a windmill with which' it may be connected'. Itis practicallyv an .established practice that the working strokes of awindmill pump occurs on the down-strokes thereof and shouldthe said windmillbeworking under a heavy load there is a grave likelihood of wrecking or disabling the mechanism. By

arranging the apparatus Yin such amanner v that the modeofoperation can be reversed as v indicated, the effort of thefcmill will, be considerably lessened and bothllight and heavy loads can be negotiated with Lequal facilitya y Attention is directed to the drawings. :The pumping apparatus comprises an outer cas-l ing 1 Whichfis flanged at 2. and 3': at the* top and bottom respectivelyfor the reception of bolts 4 and 5 which in oneinstancesecure a bed' plate 6 andthe .fl-ange ,-7 ofa supporting andguide head. 'V8together, .and inthe other instance secure a y closure plate 9:V to thebottom ofthe casing. Therclosure plate vhasga plug 10 which maybe removed for the release ofan entrapped substance. An'adjacent Q hole '11 provides for "aircirculationfandthe I drainage of any water that might accumulate through condensation or otherwise; f

The hollow -body `Y1,2 of `the headSKhas ya faced :shoulder-'17,13 abone end. and internal threads 14 at the other v The shoulder merges withfafbore 15 which is occupied byv the extension 16 of a Asupport plugv 17 whi'chi'is, eX- ternally threaded and screwed l, into .7; the threads 14 untilan-annular-stop. 18 engages kthe shoulder The latter being faced; as stated, provides a tight joint at this particu-` lar place, water entering `and lleaving thev` apparatus at an "adjacent point Yas presently explained, cannot -leakpast themjoint which V the screwing down or loosening of the plug y 17 may be had. i

A chamber 21 in the plug 17 has communication with inlet and Voutlet'passages 22 and 23 inthe tubular extensions 24 of the head 8 through openings 25. The lower end of the chamber 21 and consequently the extension 16,V is internally threaded at 26 so that the tubular piston rod 27 can be screwed in place. AThis piston rod is open at eachend. Thelower end is suitablyformed to receive a plurality of cup leathers 28 (Fig.

These cupv leathers are oppositely directed, Ythat is toA say, some point upwardly and othersy downwardly. The ideaV is to maintainzaleak-proof joint on both the up and down strokes of the working barrel 29 which moves in respect to the piston generally v 'designated SSO/andwith which the fore-going' euple'athers are a iiXedjpart. 2T he'fmode of mounting the cup leathers'is not material nor is the particular number of cup leathersemployed an essential feature. Attention will be paidto the'use of a suiicient number of cup leathers to serve the purpose, and these will besormounted thatwhen the plug 17 and its accessories are removed. the cup Vleathers arereadily detachable for replacement.

Figure 8 illust-rates one mode by which this can be accomplished.r Areduction 31-`of the piston rod receives the cup leathers and spacers 32 Aof' appropriate lengthsin alternation. The lowerextremity of the reduction Vis threaded to receive aV locking collar `When the collar isV screwed up tight by 'means ofgits lugs 34,the` cup leathers will be Vheld in firm position. l Y Y lIt. will be understood from thedescription thus farthatthe piston 30 maintainsa sta.-

Y tionary'position, this being by virtue. of its 'suspension from theXed vsupport plug 17.

'The' workingbarrel 29 isl rendered, movable by'fvrtue ofits connection with a: yoke 35 whichfisladapted toV be joined, with the reciprocating rod f (not shown) Y of f'a windmill.

The Vreciprocation of the yoke'35 is` rectilinear, to whichl end Ythe head 8 has guides and abracket 37, aiiixed to the upper end "ofthe working barrel, has openings receiv- 'ingl the shafts of the yoke.

I The lower endof the yoke A"is securedito a combined'k spider and-cylinder, lcapl 38. The

lower end of the working barrel is suitably secured in the spider, and the spider constitutes a closure for the working barrel. As

the barrel 29 works up and downv around the stationary piston 30, water is drawn in at the inlet 22 and discharged'at the outlet 23. A cap 39 conceals the boss 19 from view. The cap 39 and-head 8 have matched flanges 40 through which bolts 41 are passed to secure the capin position. The spider 38 has lugs 42 that Vride in'guides'43 along the walls of the casing 1 and impart to the spider the additional function of a crosshead.

Inlet and outlet check valves 44 and 45 are connected with the corresponding passages 22 and-23. The pumping apparatus is connected in a pipe line 46thelatter including an air chamber 47KA which has a relief valve 48 of any knownconstruction. Reverting to the bed plate 6 it is observed in Figures 1 and 5 that this is held down to the foundation 49 by anchor bolts 501 This foundation' Imay comprise the concretelining of a. pit, thev purpose ofthe foundation being to support the pumping apparatus in a firm position. A plate 51 covers the large upper chamber of the foundation but has an. opening 52 in which the yoke 35`reciprocates. y

The operation is readily understood. The yoke 35 is connected with a rod or otherreciprocating part of a windmill, and as the yoke reciprocates the movable working barrel 29 is caused to move up and down inrespect tothe stationary piston'30. Uponitheperformance of a down-stroke the tendency to.- ward the creation of a vacuum in the chamber of the barrelf29' below the piston 30 will draw water through the inlet check valve 44 and passage 22. v

VvThe following 11p-stroke of the windmill and consequently of the workingbarrel 29 will cause a discharge of the water in the outlet passage 23 and through the check valve 45. The oppositely directed cup leathers 28 prevent the leakage of water-past the'piston 30 on Ythe respective strokes. of the working barrel. y

Should it become necessary to replace the cup leathers it is only necessary to unscrew the support plug 17 from its mounting in the head 8. It is observed in Figure 4 that the body of the plug comes substantiallyiiush with the top of the head 8. Thus` when the cap 39is removed, the boss 19 will'befully accessible, either yfor the application of a wrench orofa'barinthe crossed holes 20.

VUpon unscrewing the plug the entire piston and its tubular rod can be lifted out. o lIt will be unnecessary to disturb the working barrel constitutes the' support "of the entire apparatus.V The various parts of the apparatus stufHng boX or packing tube of some kind in` addition to the customary cup leathers on the piston. Generally the f piston vcup, leathers point in one direction so that a leakage of Wa.

ter can occur on the suction stroke. But by e providing cup leathers of the form in Figure 8, one set will check any possible leakage pastthe other, the cooperation being such as to obviate the need of astufling box between the working barrel and the piston rod.

While the construction and arrangement of the improved pumping apparatusis that of a generally preferred form, obviously modifications and changes may be made with- Y out departing from the spirit of the invention or the scope of the claims.

I claim:
