Suitable valves 2e [and 25 control the ingress of `the liquid from fthe' base to the head through the pipes 22 and 23 respectively, the said valves being provided with caps 26 screw threaded in the upper. side of the head 4, and through which access may be Ahad to said valves.

'i if pivoted as at 4t2 to the frame work 12 and e rock said lever so that the lovverend. of same will move forwarr'lly.

Asrtllie lower end of said lever is moved forwardly l the lowerl end oli' the leverll willengage the teeth ot the gear wheel 37, and rotate thev latter and the'pointer 33 connected thereto'` backward step by step. This operation' isl f continued until `the pointer reaches zero, I by which .time the five gallons are. ldiss,4k charged. IAfter eaclrrocki'ng of the lever by the pins it is returned to the position'j which surrounds the pivoted point of said lever. vIn this position the pawl 1.3 is free of the teeth of the gear wheel 37 so the lat- H l l ter may be rotated when. the pointer is moved inpredetermining a new quantity;` "f As the pointerlfl is always moved .iirorie direction durillg the discharging operation of the pump, it will be seen that it may bei` moved inthe shortest direction'. to predetermine vthe quantity to be discharged, `that is,-` L. if a quantity above five gallonsr isv to be discharged, Mthe pointer 133' may be moved to.- ward the lel't `in Fig; 5 `and for any quantity not exceeding five gallons, t'o the rhg'ht.` The u movement of the p ointer in either direction` unlocks the discharging. means 'as herein-"m` after described'. I `v e 'In single cylinder double "acting pumps without the equalizing rodt' whiclrwill.` i ltial. that.y the piston be returned to normalfor starting position in. discharging anydesired quantity because less liquid .is di. ",arged upon the up stroke of the piston than .upon L the down strokedue to the 'displacementof.' j some of the liquid by the piston rod.v Ilere` p tofore when it `was desired. to discl'iaige quantity which exceeded that dischargedv b v a' complete 'reciprocation of the pis'lzoiriinfl'f` which did not amount to that dischf'trged by means were provided to automatically limitthe stroke of the piston se that the li'l'nited f reciproca tion of the pistou `would discharge the quantityl exceeding a 'complete reciproc tion, and therefore, it is desired to'claiur this feature broadly -without regard to -thev character-of the mecl'lahism employed; Td accomplish this i1-osait, the tollowing mech-i auism 'has been devised: h/[ou11ted-1lpo1i"the e'xtrcii'ie inner-end ofthe sleeve 36 andforming a part of the gear 37, is a disk 46 pro- .di 2o The finger 57 is 5a a partial rotation.

Upon the movement of the knob 32 to predetermine the quantity to be discharged, the tooth 47, (Fig. .7), will engage a notch48 in a disk 49, and give the latter with concave portions 5() and -51 which engage'tie periphery of the disk 46 and said /dis'k t9/"ijs" locked therebyiin either of two positions/ The disk 49 is loosely mounted iniip'n av'stub shaft"52, suitably secured in the frame Work 12, and-is provided with a sleeve 53 which carries at its other end a bevel gear 54, the atter meshing with a similar gear 55 fast tothe work l2. `This shaft 56 has a' finger 57, (Fig. l) which, when the pointer is at zero' tands inthe path of a iiip pawl 58 attache to the lower end of the rack plate located approximately midway the length of said shaft and is only moved out of the path ot' the iiip pawi 58 when theshaft 56 is rotated by moving the pointer 33 to indicate a gallon or more. The

timing of the return of the shaft 56 'carrying V50 with 'the base 1.4l

the finger 57 by means of the lever 41,

pawl 43 and intermediate connections, is

quently the piston 1 unless a quantity comprising a half gallon is to be discharged, in

which case the last upward movement dis-v charges only a quart and thereturn movement an equal quantity, or in other words,

the nger is returned to normal position Just as the last half gallon is to be discharged, the' piston then being in itsupper position when even. gallons are discharged,

4.0 and in its lower 'position when fractions of a of the piston l in discharging a half gallon secured tothe finger' J shaft 56, with which the' flip pawl 58 c onis limited by a disk 59 'tacts, while the downward movement-of said piston is limited byv its coming into contact- Suitable t-ie rods 60 connect the base and head tosecurely hold them in place. t

The shaft 7 is normally locked and consequently 'the operating handle 11, and is released upon the adjustment of the pointer 33 to any desired 'quantity in the following manner? The part of the disk 46 secured to the inner end of the sleeve 36 that is put of the'plane' ofv the disk 49 has a V shaped notch 61, (see Figs. 5 and 9) upon its yup-per l side, in which rests the rear end cfa pawl 62l pivoted upon a stub shaft` 63 projecting from theframework 12. 'This paw] is fast to one end of a sleeve 64, which carries at its -65 .other end a pawl 65, the free end of which This disk 49 is providedl upper end of a vertical shaft 15 56, which is guided by the head 4 and .trame ing Vfrom a disk 67 secured to the shaft`7, and thereby locking the shaft from rotation. When the knob 32 is rotated, the disk 46 will also be rotated, camming the free end of the pawl 62 upwardly and through means of the sleeve 64 raise the pawl 65- out of the path of the lug 66, so that the shaft 7 andthe disk 67 may berotated. As the predetermined quantity is discharged the disk 46 will have been rotated back to its' normal position, as previously described, and thc pawls 62 and 65 returnedto their normal positions by gravity or a suitable spring. It is obvious,-that if desired, the piedetermining' feature of the invention may be used as an indicating or registering mechanism' to keep account of the quantity of liquid. ldischarged, in which case the locking should befleft oii .and the ,figures on the dial arranged so as to progress inthe opposite direction from that shown.

Heretofore in double .acting single cylinder piimps where registers have been employed to keep track of the quantity of liquid discharged, they have been. made to register the. quantity discharged by a com'- plete reciprocation of the up-stroke or the return of the piston. This construction is faultyfor the reason that if it is desired to discharge a less quantity than that discharged by a complete reciprocation of the piston, a quantity greater than that discharged would be registered or none at all.

In some instances,'it is very desirable to discharge the desired quantity by the continued movement of the operating handlel in of the piston at the end one directioitbut the great difficulty heretofore in single' cylinder double acting'self measuring,-pumps has been thatthe same amount of'iquid would'not be dischz-irged upon one=s'ti'okel of the piston as upon the other, due to the displacement of the liquid above the piston by the piston rod. This objection has been overcome by the followT ing simple and etiicient means. Extending downwardly from 'the piston, as shown in Figs. 1 and 2, is a rod 450i the same cross sectional area as the piston rod 3, which displaces the same quantity ofliquid below the piston l as the rod 3 does above. The rods 3 and 45 pass through suitable packing boxes 68 and 69 which are-mounted upon the head 4 and tively.

It is to be understood that the dial 34 may be divided into fractions of agallon representing pints and quarts, or any other quantities desired, as well as the gallon fractions as shown.`
