DISPLACEMENT PUMP.

Application filed August 11, 1921 7 Serial No. 491,508.

My invention relates to displacement pumps.

An object of my inventionis to provide an improved displacement typepump. Another object of my invention is to provide an improved displacement type pump havin g improved automatically controlled: means for-the supply of the pumping medium thereto. A further object of my invention is to provide an improved displacement type pump in which the control may beaccomplished without the reliance upon floats and by the weiglit'of the liquid being pumped. Other objects of my invention will hereinafter more fully appear.

In the accompanying drawings I have shown torpurposes of illustration one form 'which my invention may assume "in practice.

In these drawings, 1

Fig 1 isa side elevation of the illustrative form-o1 my improved pumping 'mechanism'; parts being shown in section.

ig. 2 is a plan view of the mechanism shown in Fig. 1. 5 I

Fig. 3 'is'an end View, the view being taken from the right hand end of Fig.1.

Fig. 4 is a central vertical section on the liue 44 ofFig. 1. 1

Figs. 5 and 6 are details of the valve mechanism. I

My improved pumping mechanismcomprises a pairof displacement tanks and 2 rigidly mounted upon a beam 3 which is in turn pivotally mounted as best shown in Fig.4 upon a base member 4 which is provided with upstanding brackets 5 pivotally supporting said beam '3, the latter being in turn provided with depending hangers 6 for supporting the same upon the transverse shaft 7 which is rotatably mounted in the brackets 5 in suitableanti-triction bearings. In the bottoms of each of the tanks-1 and 2 there are provided common inlet and-dis:

charge connections

9 and 10 respectively, these connections communicating with transversely extending p1pes'11and 12'secured to

theconnections

9 and 10 beneath the beam 3.- The transverse connections 11 and 12 communicate at opposite sides-of the beam 3 with inlet and discharge connections 13 and 14 respectively, there beingprovlded check valves '15 andlG permitting flow only toward the tanks in the-connections between the line 13-and the pipes 11 and 12, and 17 and 18 permitting discharge only between the line 14 and the pipes 11'and 12.' It will bc'evident from an inspection of Fig. 4 that the pipes 11 and '12 communicate beyond :the check valves with Xs; 19 and 20, therad- 'j'acent sides of the latter being blanked o-fi" and the remote sides being provided-with tubular sections 21 and 22surrounded by -.

suitable glands

28 and 24 whereby a movtable but fluid tight connection may bear ranged between the inlet. and'discharg e lines 13 and 14 and the tanks 1 and 2.*' v

It will he notedthat the beam 3 carries at one end thereof a'depending. vertically disposed rack 25 adapted'to' cooperate with a spur gear 26 mounted upon a horizontal the base 4 and thatthis shaft carries a suit- -.ably keyechor otherwise held with respect thereto, arm 29 having sa relatively heavy weight 30-thereon, the weight 30 being so proportioned relative to its leverage 5 as to 'tend to counterbalance the weight of either ofthe tanks as they fill while' the other" is emptying. Suitable limit'or stop means 31 and 32 are provided upon the base 4 to pre- Qvent' excessive tipping of the beam 3.

For the purpose of supplying and exhausting air or other suitable pumping media to-the tanks 1 and 2 whereby to 'cause the I support uponran arm 35- projee ti'ng upward from the end of the beam opposite the cooperate with the stationary abutment member 42 secured to theframe 4, there beshaft 27 journaledas-at 28 uponthe end of -.discharge of the liquid from the' tanks in alternation and to permit their "re-filling ing" springs 43 and 44 surrounding the stem 38 betweenfthe abutment 42: and thestops 40 and 41 to cushion the action-1t will thusbe evidentthat as the be'am'tilts'clo'ckwise,-the-'valve willyat approximately the I end ofthe tilting movement, assume a po-v I sition near"the top of the casing, as its downward movement'will be'interrupt'ed by engagement of the spring betweenthe colla r 40 and the abutment'42 with said parts 'nects with the 'linel56 leading totthe top of the tank "1. Port 54: communicates with the .line 57 leading to the top of tank 2 and port 53' leads to exhaust. It will be noted that the-valve 37. isof a type in which a port 58 extends betweenand opens through the 7 surfaces of the ends of the D, being similar in construction to the w-ell-known- Allen valve which is familiar in steam engine use: It will be .notedthat the valve 37 and the port'58. are so constructed that the tanks maybe connected together when the valve is insubstantiallymid-position and .priorzto' the. connection ofthe tank, which 'has been. receiving live air,'with exhaust wherebyaconsiderable quantity of air may be bypassed from one tank to the economy will be obtained. 7 The mode of"operationofthis'mechanism willbe readily apparent from the descripother and "tion so. far :given. .Assume' that the parts 1areiin the'position shown with aircut ofi' from both of'the tanks, the: valve stem 38 will then'ibemoved by hand to one of its extreme positions whereby to supply air under pressure to one. ofthe tanks and connect the other with exhaust" In order to prevent tlIB WZIStBf'Oftllelfiuld being sup- ;plied to the/tank connected with air, one .or theother of the manually-controlledstop .1valves '60 and 61 in: the lines 56 and '57, re-

spectively, .will be closed. Thetank in which atmospheric pressure alone exists will ac- .cordinglybegin to -fill.;by reason" of the admission through the check valve 15 or 16 1ofliquid which flows in :by gravity. As the the weight 30 will be swung in oneidirection :or theother, it being noted that the force iqui-d rises in the tank whichis, being filled,

necessary to moveythe weight increases as -.-the: weight moves more nearlyctoward la horizontal position. Approximately at the 1moment when, theweight has reached horizontal position, the tank will become filled :andasthe arm reaches and;crosses its horizontal position, its resistance will decrease and so arelatively rapid tilting'movement of the beam will cause: the valve-chest; t0

move-to such-an extent as to cause it to move .relative-to-the valve, whose path-is limited as described, in such manner as to shift relatively to the valve first to mid-position and then. to reverse position. As this occurs, the valve or 61 which was closed may be opened as there will no longer be any dis charge of waste air. The air admitted to the tank which had previously been filling will begin to discharge the liquid therefrom and the other tank will begin to fill under the gravity head of the liquid, the weight 30 assisting the parts to return to initial position at such time as the tanks are equally filled. The discharge of liquid from the tank first filled will continue while the filling of the other will simultaneously 0 on until the; tank first filled is emptie and the other full-.- rThegrelative vpositions of the valve chest 36 andthe valve 37 will then be reversed as, previously described and the original operation continued, the sole d1fi'erence being that the; tank-last filled will be =discharged.- The systemnow being in full operation will continue to operate automatically'as long as liquid is supplied to it and pressure fluid is'av'ailable' to cause the discharge of the liquid from; the tanks'alternately. It will be evident that tilting movement of the beam 3'will be limited to the proper amount by the stopsBl or.-,32. a

While l have inthisapplication specifically described one embodiment which my invention may assume in practice, it will be understood thatfthis form of the same isshownjfor purposes, of illustration and that the invention maybe modified andjembodied in various other forms without-departing from the spirit or the scope'o-f the appended claims.
