.SELF-MEASURING PUMP.

SPECIFICATION forming part of Letters Patent No.'534,464, dated February 19, 1895, Application yfiled June 28,1894. Serial No. 515.997. (No model.)

To all whom it may concern:

Be it known that I, SYLVANUS F. BOWSER, a citizen of the United States,'residing at Fort Wayne, in the county of Allen and State of Indiana, have invented a `new'and useful Self- Measuring Pump, of which the following is a specification.

This invention relates to self-measuring pumps; and itlhas for its object to eifect certain improvements in pumpsof that character wherein means are provided for accurately gaging the quantity of liquid to be elevated without theuse of supplemental measuring devices.

To this end the main and primary object of this invention is to provide certain improvements in the operating mechanism for pumps of that character especially employed in lifting oils and other heavy liquids, whereby the quantity of oil may be properlyand accurately gaged, and at the same time registered, when large quantities are being pumped.

With these and otherobjects in view, which will readily appear as the nature of the invention is better understood, the Vsame consists in the novel construction,combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawingsz-Figure l isa side elevation of a storage tank, partly in section show-y ing my improved pump used in connection therewith. Fig. 2 is an enlarged detail in perspective of the pump operating mechan ism. Fig. 3 is a central vertical sectional view of the construction shown in Fig. 2. Fig. 4. is a transverse sectional; view on the line of Fig. 3. Fig. 5 is a detail sectional view on the line y-g/ of Fig. 4. Fig. 6 is a similar view on the line .e-z of Fig. 4. Fig. 7 is a detail in perspective lof `the adjustable stop collar carrying the sliding stop-stud.

Referring to the accompanying drawings, A represents an ordinary storage tank in connection with which the herein described pump is preferably employed, and this storage tank is usually intended to be arranged in the cellar of a store or below the iioor thereof whereby the contents,rwhich are oil or lother liquid, may be conveniently pumped up into the store-room by the operator. This storage tank A, is provided at thej'bottom thereof with a drop pump-pocket B, which is of a.

depth sufficient to accommodate the cylinder of a pumping apparatus, said pocket usually being about eighteen inches deep. The pocket B, extends below the plane of the tank bottom so that the entire liquid contents of the tank can be substantially drained by the pumping devices employed in connection with the tank, the cylinder C of such pump being adapted to be seated in the said pocket,

and at its upper edge the pocket is entirely encircled or surrounded by the surrounding rim-Bange extended upwardly from the bottom of the tank around the upper edge ofthe pocket. The upwardly extended rimange is usually about one inch high and serves to keep back all the sediment that would otherwise naturally drain into the pumpspocket and clog up and interfere with the free working of thepump.

The pump cylinder C, is of the ordinary construction, and in the present invention is preferably bolted to the lower end of the frame upright D, which is of a length sufficient to extend above, the iioor andto a con- Y venient height for easily operating the pump,

land said pump cylinder C, at the lower end of said upright, has connected to the lower end thereof the pump discharge pipe E, which rises parallel with the frame upright to substantially the same height as the same. said pump cylinder O, accommodates therein the piston head E,`to whichl is attached the lower end ofthe pump rod F, working through the top of the tank and the iioor above which the apparatus projects, and having attached The to the upper portion thereof the vertical rack bar G.' The rack bar G, is provided at its upper and lower ends with the'off-standingcollars H, embracing the pump rod and one of which collars receives the set screw I, to

clamp the said rack bar in pump rod.

The rack bar upper end of the pump rod position on the is guided to move through a top guide open ing J, in the o-standing bearing bracket K, having an inner iianged end lc, bolted at one side of the frame upright D, at the upper end thereof. The said off-standing bearing bracket K, is of a substantially hollow construction having the opposite bearing sides- L, from the inner faces of which project inwardly extending guide lugs Z, disposed at IOC) one side of the attached rack bar G, to assist in holding the pump rod steady in its vertical reciprocations, While -at the outer end of the bearing bracket is located a` top pipe opening M, to receive the extreme upper end of the pump discharge pipe E, which is held firm in this bracket by a set screw m, engaging a threaded opening at the outer end of the bracket and impiuging against the, said pipe.

A reciprocatory movement is communicated to the pump rod from the meshing cog pinionN,mountedon the short operatingshaft O, journaled in the opposite bearing, sides of the oft-standing bracket- K, and one endv of said short operating shaft O, projects through, the short circular bearing collar P, projected from the outer face of one of the bearing sides of the brackets, and this projecting end of the short operating shaft is squared to removably receive one end of thecrank handle Q. At the end which is attached to one end of the operating shaft, the said crank handle is provided with a short laterally extended hub portion R, working against theouter edge of the bearing neck P, and with a squared to tit over the squared end of opening R', said shaft. The said crank handle is detachably held in position by means ot the securing screw fr', engaging a threaded opening r2, in the outer end of the short operating shaft. The crank handle is turned back and forth in operating the pump, it being obvious that the meshing cog pinion will communicatea reciprocating motion to the upper rack end of the pump rod and thereby operate the pump to discharge a quantity of oil out throughthe discharge spout S,1eading from the pump discharge pipe near its upper end.

The short hub portion R, at one end of the crank handle, accommodates thereon the circularly adjustable stop collar T, provided at one i side with a stop-lug t, and a threaded opening t', to receive the set screw t2, which holds the said collar fast` in any adjusted position on the hub of the crank handle, and the movement of said crank handle is limited by the stop lug, t, of said stop collar coming in contact with the'stop pin U, projecting from one side of the, bearing bracket. When the piston of the pump is raised to itsfull height the lug on said collar is` adapted to contact with said pin, and it will therefore be obvious that by adjusting the collar and moving the stop lug thereof toward or away from'the saidstop pin, the stroke of the pump can be made longer or shorter, so that the exact amount of liquid to be drawn by a complete stroke can be accurately regulated or gaged.

At one side of the stop collar T, and adjustably mounted on the bearing neck P, is a secondstop collar V, provided aty one side with a threaded opening fu, to receive a set screw/v', to hold the second stop collar fast on thebearing neckin any adjusted position. The said collar V, isfurther provided with a recessed lug W, Which accommodates thereinthe sliding stop stud w, having attachedu to one end thereof the short finger wire or piece'w', which is grasped by the fingers to project one end of the stop stud beyond the outer face of the second stop collar and in the path of the stop lug t, on the main stop collar T, and thereby provide means for shortening up the stroke to one-half or one quarter, or other fraction desired.

As illustrated, We may assume that the outer or main stop collar T, is adj usted so that one complete stroke of the` piston will draw one half a gallon, While theinner or second stop collar is adjusted so that when the stop stud is projected, the movement of the crank handle will only give one half a stroke and thereby pump ono quart o tho liquid; to bo drown With tho honor` operative moohaoiom ad,- J'uotod to sosolooo holo o gallon of liquid at each strokeit will be obvious thatin1 drawing large quantities, forinstauce tive gaiionsor more, it would require the operators closest attention to" count ten or more haii-gallon strokes,`and torelieve the operator of such ooon and.V to. aoouratola iodioeto t11o -osooo amountof liquid'being piirnped,i1le1nploy a register dial X, The register dial X, is mounted on the pivotscrew wc., at one side of the oft-standing bearing bracket and isoprovided upon itsperiphery with suitable.1 graduations from one gallon up, and also with a ratchet portion or disk Y, the teeth ot'` which are engaged oneatl ajtimelat the endot each full stroke by the gravity pawl or, dogg/,pivotally mounted in the recess y', at one` endfof the short operatingshaft0,ivvliicli isjournaled below theregister,diai.` A pointer finger Z,

When the` pump isadjustedlto operate in connectionwith the inner or second stop collar and its` sliding stop stud, the registering device just` described ishardlynecessary` and will notzoperate."

From the above it will be seenV that the herein-described pump can be accurately gagedtodraw any amount of liquid desired at one strokeof thepistomwhile at the same time simpleand efficient meansare provided for oooororoly rogiotorns extra. largo quontities ofI the liquid being pumped, andlwill haveit understood thatchanges` in the form, proportion and tho minor details ofi ooootruotion may be resortedi to without departing from the principle orn sacrificing any oi the advantages of;` this invention.
