'amended April so, v,12328; 3io o. G. 757) This invention relates to a measuring device which is particularly adapted to be used in ineasuring and dispensing predetermined volumes of explosive filler forY introduction in explosive shells or bombs, but is not limited to the singlefpurpose stated as it is also of utility in measuring predetermined volumesv or bulks `of any desi-rable fluent material. l n

It'is an object of the invention to provide a simple, efficient and improved device for intermittently measuring' predetermined volumes of uent material, positive in its action, and having the movingparts arranged in compact functionalV relation so arranged as to permit, ready and thorough cleansing.

Fig. 9 is a view of a modii'ed measuring sump or cup for use with the device shown in Figs. 6 to 8.

Referring now to the drawings by characters of reference and more particularly to Fig. 2 there is disclosed a container or reservoir generally indicated at I0, which may beI of any desirable configuration, volume and construction; but, herein shown for the purpose at hand as comprising a generally cylindrical structure having. spaced parallel inner and outer side wall members I l and I2 joined at their upper edge portions by an annular plate i3 in sealed relation and having bottom portions indicatedY generally tablishing chamber 255, and outlet i9 and. vice-versa is proat Mv and l5, respectively, disposed infspaced sealed relation. Y v

The bottom portion ,lltf includes an annularl inwardly sloping member Hi concentricallysecured at its outer peripheral portion to the wall Hv in sealed relation and a cylindrical depending measuring cup or sump-l1, ofany predetermin'edvolurne secured at its upper peripheral edge portion to` the inner peripheral portion o-f the annular member i6 in `flush and sealed relation.` The bottom portion of the cup I1 is inwardly inclined `conveniently on substantially the sameslopezas the annular member lr6 and has secured thereto in coaXially-disposedrelation a depending tubular outlet member IS. The outer bottom portion l5` comprises-the inwardly sloping member 20 secured at its outer peripheral `portion toV the lower edge portion of wall member lf2 in vsealed relation and an integral or similarly aixed cylindrical depending` member enclosing the outlet member i9 in spaced coaxial relation with the lower portion irl-turned. or provided with a flange as at 2.2-secured to the. tubular outlet in sealed relation.' j

' Inlet and outlet couplings l23 and 24 are affixed to the depending cylindrical member 2i and wall member i2., respectively, which. provides for the circulationof a suitable heat transfer medium between the spaced. walls of the reservoir if desired. Y v

Mechanism` for first cutting off intercommunif cation betweenthe reservoir orstorage chamber and the measuringechamber 25 formed by the measuring cup o-r sump I1 and thereafter esintercommunication between the vided which comprises a pair of reciprocal valves 21, 28 and asuitable linkage generally indicated at 29A adaptedto relatively reciprocate the valves in proper relation.

l Valve 21,' which closes theingress opening of the tubular outlet I9 attached to theV cup I1, comprisesfa circular valve element 3i! press fitted on the valve stem and having a lower inwardly inclined surfaceV 3l corresponding substantially with the, slope of'bottom I3 of the measuring cupvand `a plurality of circumferentially spaced depending clearing iingers 32 disposed coaxially ofk the .elementil on a radius adapting them to snugly iit within the tubular outlet member I9. The junction of the outer surfaces of fingers 32 with theksuriace 3l oi the valve element is undercut to form an annular groove 33. adapted to receive a gasket' 34 of any` suitable' character and a valve stem or actuating rod 35 is coaxially secured to the upper face of the valve element 38 extending upwardly to a suitable position without the reservoir where it is terminated in a portion of reduced section 36 forming the shoulder 31 and having a transverse opening 38 therethrough in proximity of its upper end.

The valve 28 closes the ingress opening of the measuring cup I1 leading from the reservoir chamber 25 and comprises an annular valve element 39 provided with a lower spherical surface 40 adapted in the seated position of the element to slightly protrude into the chamber 26 to compact the material therein and force occluded gases in the material through a vent as hereinafter more particularly described. Valve element 39 is slidably fitted over the valve rod 35 in snug relation and has its spherical face 40 undercut at 4I to receive an annular gasket 42 of any suitable character adapted to seat upon the inner edge of the annular bottom forming member I6 in fluid sealed relation. A valve actuating stem 430i tubular section is secured to the upper face of valve element 39 and extends upwardly to a position without the reservoir in concentric relation to the valve stem or rod 35 where it is terminated adjacent the shoulder 31 on the latter rod. The valve stem 35 is also formed to provide a stop 44 so that when the valve 28 assumes the position shown in Fig. 2 it will engage the stop 44 and prevent further relative movement of the valves 21 and 28 upon exertion of an upward force on the valve stem 43 urging the valve 28 to a position above which it occupies in Fig. 2.

Valve 28 and the cooperating portion of valve stem 35 form a snug sliding fit to prevent flow of material in the reservoir chamber into the tubular valve stem 43 when the valve 28 is in the raised position shown. Intermediate the valves 21'and 28 the valve rod 35 is grooved as at 45 in suchlmanner that the groove will establish intercommunication between the chamber 26 and interior of valve stem 43 when the valve 28 is in its seated position and the valve 21 is in its raised position whereby chamber 26 will be in unobstructed communication with atmosphere through the tubular valve stem 43.

The linkage system 29 for actuating the valves comprises a pair of opposed plates secured to opposed side portions of the valve stem 43 in upwardly extending relation with their upper end wall member I2. A standard 55 is secured to the wall member I2 in upstanding relation and is slotted as at 56 to receive the projecting end of the lever 52 in such manner that the lever will engage the upper surface of the slot under the action of spring 49 when the valves are as shown in Fig. 2. An actuating lever 51 is pivoted at one of its ends 58 to the valve stem 35 within opening 38 and extends outwardly through the slot in standard 55 to provide a substantial hand grasp portion 59. The end of lever 52 projecting without the standard 55 is connected by the link 60 to an intermediate portion of lever 51.

In the operation of the form of the invention thus far disclosed, assuming that the valves 21 and 28 occupy their normal positions as disclosed in Fig. 2 with lever 52 engaging the upper surface of slot 56 the reservoir will be filled with any desirable fluent material and a suitable heat transfer medium will be circulated between the walls of the-reservoir to keep the material inthe reservoir in the proper state of fluidity, if necessary. When the reservoir is lledthe sump or measuring cup chamber 26 will be lled through the opening past the raised valve 28 and the device is now conditioned to dispense measured volumes of the material. The lever 51 is depressed by the portion 59 which causes the lever 52, through the link 68, to fulcrum about its pivot 53 and therethrough depress the plates 46, valve stem 43 and valve 28 against the action of spring 49 resting on the valve stem which at this moment is immovable downwardly because of the interengagement between the valve 21 and its seat upon the bottom I8 of the measuring well I1. When the valve 28 is .depressed sufficiently to engage its seat on the bottom member I6 communication between the chambers 25 and 26 will be obstructed and valve stem 43 will be immobilized against further movement of depression.

Continued depression of the lever handle 59,A1

after engagement of the valve 28 with its lseat will cause the lever 51 to fulcrum about its connection with link 60 and raise the valverod 35 thereby unseating the valve 21 and providing for the discharge of the contents of the measuring j cup chamber 26 through the tubular outlet I9.

sition the vent 45 will straddle valve 28 to estabportions inwardly converged and terminating in spaced parallel portions. If desired the plates 46 may be reinforced by the transverse strut 41 as shown in Fig. 2 .and intermediate its ends an apertured spring abutment 48 is secured in such manner as to slidably receive the reduced portion 36 of the valve stem 35 below the opening 38 therein when the valves are disposed as shown in Fig. 2. A spring 49 is interposed between the shoulder 31 on rod 35 and spring abutment 48 compression to normally retain the valves in the position shown in Fig. 2 with valve element 39 engaging the stop 44. A lever supporting bracket Y 58 of any suitable construction, such as, a pair of upwardly and outwardly converging legs 5I secured to the wall member I2 and having their outer end portions disposed in spaced parallelism and terminating just slightly below the level of the normal uppermost position of the plates 46 is provided to support one end of a generally horizontal disposed lever 52 pivoted as at 53 to the bracket 50. The lever 52 is pivoted intermediate its ends at 54 to the upper end portions of the plates and projects a slight distance beyond the When the valve 28 is held in its seated position by retaining the lever handle 59 depressed and the valve 21 correspondingly held in its raised polish communication with atmosphere past the valve 28 and facilitate'discharge of the contents of the chamber 26. In the seated position of valve 28 the spherical face 40 will act to ensure that the well I1 will be filled with the same v`olume each time it is iilled by positively engaging the upper surface of the contents in the cup; and

` K the clearing iingers 32 on valve 21 will keep v60 attached to the plates 46 undersufcient. initial the tubular member I9 cleared of obstruction as well as serve to guide the valve.

When the -measuring chamber 26 is exhausted of its contents the lever handle 59 is simply released and the valves will be returned to their normal position of Fig. 2 by the spring 49.

In themodied form of valve actuating linkage shown in Fig. 5 the bracket 60 is perforated to receive the upper end portion of valve stem 35 and is suitably secured to any stationary support, which may be the reservoir. A spring 6I is interposed between the valve stems 35 and 43 as shown and acts in the same manner as spring 49 to keep the valves 21 and 28 in the normal relative position of Fig. 2. A lever 62 is pivoted ai? 011 end to the upper end of valve stem 35 and pivoted intermediate its ends by a link 68 to a lever rigidly connected to the valve stem 43.

Upon depression of the free end of lever 62' the f same relative movementsof valves. 2Bl and 21, will take place in the same sequence asin the form hereinbefore described, except in this form a spring 65 interposed between a relative stationary support 66 and the valve stem 35 is substituted for Y the standard 55V and acts to normally seat the valve 21 While spring 6I acts to normally unseat valve 28 when valve 21 is seated.

In the gang measuring and loading device,

shown in Figs. 6 to 9 there is provided a reservoir 61 of generally rectangular shape in horizontal section formed by spaced inner and outer side walls 68 and 69, joined in uid sealed relation`to spaced inner and outer bottom walls 1D and 1I, respectively. 'The `bottom walls 10. and 1l eX- tend inwardly from opposed side walls in down-Y wardly converging relation and are secured in any convenient manner in iiuid sealed relation to a bottom plate 12 disposed medially of the reservoir. The bottom plate 12 is `formed with a plurality of aligned bores 13 corresponding to the number of measuring cups or chambers with which the device is to be equipped and chamber forming members or cups 14 of similar construction are secured to the plate 12 in axial alignment with each of the bores 13. Conveniently the cups 14 are of the same general construction as the cup l1 and are secured to a plate member 15 so bored as to receive the upper end portions thereof in fluid sealed relation as indicated in Fig. 8.

In order to circulate a heat exchange medium about the cups 14 they are enclosed by a casing 18 having parallel side and end walls secured to the plate 15 in sealed relation and an arcuate bottom wall through which the tubular outlets 11 of the cups 1:3 project in sealed relation` A suitable heatving or cooling medium may be circulated about handle 92 and may be freely oscillated about its axis. v

As clearly shown in Figs. 7 and 8 the upper end portions of the, valve `stems 84 project through one leg `of an-angle iron support 93 carried by a wall member 94 secured to the rear edge portions of the wallprojections 9| and are operterposed between the angle support 93 and collars on the valve stems 8d under an initial loading as shown in Fig. 8. Theflinkage for actuating each 'pair of cooperating valve stems comprises a lever 95 secured intermediate its ends to the shaft` 99, a lever 91 secured at one end through a suitable pin inserted in the slot 88 of the valve stem B and pivotally interconnected at its other end with lever 9.8 by means of a link, 9S, a lever 98 having the cups 14 within casing 16 through the inlet and outlet therein as indicated at 18 and 19, respectively.

The plate 15 with its assembled cups and casing is detachably secured to` plate 12 in any desirable manner, as by the stud fastenings 80, with the cups 1li in axial alignment with the cooperating bores 13 in plate 12, and a suitable gasket 8l interposed between the plates 12 and 15 to for a sealed connection. Y

Each cup 14 is controlled by a pair of cooperating valves 82 and 83 similar in construction to the valves 21 and 28, respectively, of Fig. 2. The valves 82 are each provided with a valve stem 84 slotted intermediate its ends as shown at B5 and adjacent its upper end at S9 for purposes hereinaiter made moreapparent. The valves-83 are axially bored to receive the valve stems 84 in snug sliding relation and are counterbored to receive tubular valve stems 81 disposed concen trically of the Valve stems 84 as clearly shown in a bifurcated end 199 pivotally receiving the pins 89 of the bushing 88 secured to valve stem S1 and pivotally interconnected at its other end with lever 95 bymeans of a link IBI, and a link |82 pivotally interconnecting the levers 91 and 99 intermediate their ends. A spring |83 is secured between the levers 91 and 99 of each linkage to normally hold the valve 88 in its uppermost position relative to the valve 82.V When Valve 82 is raised and valve 83 lowered the slot 85 in valve stem 84 will establish intercommunication between the interior of valve stem 81 and the cup M thus permitting communication with atmosphere through ports IMV in the upper end portionV of valve stem 81. v

The top of the reservoir may be closedbva hinged closure 85, which can be raised to give access to the shaft 99 and associated valve actuating linkages, and arclosure plate |96` hinged to the wall member 9d adapted to be raised to give access to the interior of the reservoir.

For the purpose of rendering the device` capable of use for dispensing measured amounts of explosive or similar substance of different quantities, measuring cup units having measuring cupsv 14 of dilferent volumes, as shown in Fig. 9 may be substituted for the cup unit shown in Fig.l 8. The cups 'lll' of Fig. 9 are smaller than those shown in Fig. 8 but have their upper end portions enlarged to conform to the bores 13 in bottom plate 12 of the reservoir.

As well understood in the art a heat exchange medium may be circulated between the inner and outer walls defining the reservoir 81 in any suitable manner and a vent stack |81 and deluge connection 188 maybe provided if desired.

Theoperation of this form of the invention is very similar. to that of the form shown in Fig. 2.

. With the reservoir lled or partially filled with explosive or similar substance and the valves Fig. 8. The upper end portions of the valve stems 81 have secured thereto bushings 88 which receive the valve stems 84 in snug sliding relation and are provided with opposed pins 89 for a purpose made clear subsequently.

rlhe actuating linkage for each pair of cooperating valves 82 and 83 is identical in construction and all of the linkages are simultaneously operable by common means, to which end a rock shaft 90 is journalled in any suitable manner to extensions 9| of the inner walls 68 of the reservoir 61 in parallel relation to the cups 14. The shaft 98 is provided with an actuating disposed as shown in Fig. 8 the cups 14 or 14 will be lled. Vessels, such as bombsor shells, are disposed one under each tubular outlet 11. The actuatingY handle 92 is depressed thereby tending to rotatefshaft 98 and the lever 95 and links 98,

IGI of each linkage counterclockwise as viewed in Fig. 8, which will result in lever 99 pivoting about its fulcrum on link I 02 and the-lever 91 pivoting about its fulcrum on valve stem 84 to depress valve stem 81 and seat valve 83 on bot-r tom plate 12 in closing relationto bore 13. After valve 83 isY seated upon the bottom plate 12 the lever. 99 will pivot about the pins 89 on bushing:

88 upon continued depression of handle 92 and the lever Sl will pivot about its fulcrum on link |02 raising the valve stem 84 to unseat valve 82 and permit discharge of the corresponding cup 14. In the raised position of valve 82 and lowered position of valve 83 the slot 85 in valve stem 84 will establish communication past valve 83 with atmosphere through the valve stem 8l and perforations |84 thus permitting free discharge of the contents of the cups 14| therefrom. After discharge of the cups 14 the valves may be restored to normal as shown in Fig. 8 by simply releasing the handle 92 so that the springs 95 and |83 will be free to move the valve stems 84 and 8l to their normally biased positions in a manner just the reverse of that above described.
