In. they liquid vender shown'L inthev dravv` ings as an embodiment of`- the invention ally of the general trameparts, allot the larger operatingparts. together with sever ali of" the smaller ones, may, be die-castings ot a.y sfu-it;- able metal, suchk as zinc, and" all of' the remainingparts of the machine Vare so designed as to be readily manufacturedr from' easiiy obtainable suitable materials. The particu# lar construction illustrated; in the drawings asian embodiment of the invention Wiilfnow be described in. detail; with reference to the drawings.
A singlehollow die-casting forms the main n frame; part ofthe machinewhill includes the most of an expanded base 11,. the majonportion of a hollow substantially rectangular standard 2 which rises from the hollow base 1,and also comprises a top wall 3 for the upper end of the standard 2, which forms the bottom of a container for the liquid. The lower portion of the front of the standard 2 and the upper front portion of the base 1 are formed by a die-cast removable front door 4, which has an interlocking engagement at its upper end as shown in Figs. 3, 8 and 10, and which is secured place at its base end by means of an ordinary lock 5 which has looking detachable engage ment with the upper end of a lock stud 6, se-
- cured to the bottom of a money pan 7 which telescopes into the bottom of the base 1 and is also removably held in place by means of the look 5. Internal frame parts forcirrying various parts of the operating mechanism comprise'a lower bracket member 8 Ywhich.
secured to the rear wall of the standard 2V by means of a pair of screws 9, a mechanism frame 10 similarly secured to the rear wall of the standard 2 by means of a pair of screws 11, and a dial-formingindicator frame 12 in the upper and forward part of the standard 2 which is secured to the front and upper part of the mechanism frame 10 by means of a pair of screws 13 which are screwed in from the back of the mechanism frame 10, these frame parts 10 and 12 being pro-vided with abutting spacing bosses to receive these screws 13. These frame parts 8, 10 and 12 may all conveniently be zinc die-castings.
An upright cylindrical glass container body 14 rests upon a shoulder formed within a peripheral upstanding flange 15 on the pro- ]ecting dish-shaped standard top 3 which thus forms the bottom ofthe container', this joint being provided with a gasket 16. The upper' end of the glass container body 14 is provided with a die-cast cover cap 17 which is flanged downwardly around its periphery and is there provided with a sealing gasket 18. VThe central portion of this cover cap 17 projects upwardly in the form of a housing 19 for accommodating internal parts'which project upwardly above the top of the container body 14. rlhe front of this housing 19 is ofy circular shape and carries a name plate 20 which indicates the use of the machine, that is, the nature of the liquid vended. The container body 14 and its cover cap 17 are Vfirmly clamped and rigidly secured in place by means of three screw bolts or rods 21 which pass through the cover cap 17 and screw into lugs 22 formed on the container bottom 3. Y
Near its rear edge the cover cap 17 is provided with'a screw plug 23 for filling the container.
An upright pump cylinder 24 has its lower end securely sealed against the upper surface of the container bottom 3 by means of an interposed gasket 25 and is firmly secured to the container bottom by means of a pair of screws 26 which pass through lugsas shown provided on the lower end of the cylinder. The lower end of this pump'cylinder 24 is provided with a sealed outlet or delivery passage 27 which entends laterally into a lug 28 provided on the cylinder. A small delivery7 tube 29, which may suitably be of copper, is sealed into the lug 28 in communication with the cylinder passage 27 and together therewith forms a continuously freely open outlet or discharge conduit from the bottom of the cylinder 24. This outlet tube 29 extends upwardly above the liquid level and above the top of the container body 14 into the housing portion 19 of the cover cap 17 and its upper end has a freely open outlet turned downwardly. The down-turned upper end of the small outlet tube 29 loosely enters and freely opens into the upper end of a considerably larger vertical overflow pipe 30, which may be of brass, having its lower end screwed into he container bottom 3. A delivery spout 3l communicates with the lower end of the overflow pipe 30 and extends to the outside of the Lmachine where it projects at the left side of the upper portion of the standard 2 below the container bottom 3. This spout 31 may be a piece of bent copper tubing cast into the main frame part of the machine as an insert.
The pump cylinder 24 is provided with a pair of oppositely arranged spaced upward extensions 32 which form a piston guide without adding anything to the effective length of the cylinder 24. Apiston 33 of inverted cup shape is adapted to reciprocate into and out of the open upper end of the cylinder 24, being guided bythe guide extensions 32 when it rises above the top edge of the cylinder 24 between these rather widely spaced piston guides. Since the piston 33 when it is reciprocated rises at'its lower edge above the open top of the cylinder 24, it is obvious that this cylinder can then freely fill with the liquid without need of providing any inlet valve for this purpose. However, in such a construction, when the piston rises in the cylinder, it would have a tendency to draw air into the cylinder throughthe small outlet tube 29, after of course first drawing out the small quantity of the liquid contained in this tube.
Therefore, the top web of the piston 33 is provided with a'suitable number of relief openings as shown in F ig. 5 which are controlled by an inwardly opening valve 34 of substantially a usual form. The cylinder part may be a Zinc die-casting, while the piston and its valve may suitably be of brass.
The piston 33 is further guided between the cylinder extensions 32 by means of a pair of' top extensions 35 on the piston which have inner plane opposed faces spaced apart to the same extent as the spacing between the piston guides 32 at their opposed edges so that thereby a large slot is provided which comprises the space between the two piston guides 32 and the space between the two piston extenrecesso4 sions 35. A piston pin 33 extends between andi-shred at its ends in the respective piston extensions 35.
Anz operating link 37, which may be a brass stamping, is provided at its lower end with an eye by which it is pivoted on the piston piny 36.- This link extends upwardly at a slight outward: inclination and at its upper end. is turned outward horizontally. This turned over upper end of the link 37 has rigid-ly connected thereto the u'pperend of a vertical slidable operating rod 38 which eX-k tendsdownward through and projects tor.k
some distance below' they container bottom 3. This connection between the piston link o7 and the operating rod 38 is made by means of a rather extended threaded portion on the upper end yof the rod which passes through-- the end of the link, which is {irmly held and clamped in place between a pair of nuts-319, thereby providing an adjustable connection between the piston link 37 and its iperating rod 38 by reason oi which l presently more cl-early appear, the piston 33 may be adjustably raised or ylowered in 'the cylinder 34- for thereby varying the effective length of the stroke of the piston .vithout any change in the actual length ot the path of( its reciprocating movement. ySuch adjustment obviously will correspondingly vary the` measured quantity of the liquid livered from the cylinder, by reason ot' tno' fact that the length of the path of travel et the pistonv within the cylinder below the up-y perend.v of the latter may thus be made longer or shorter.
The upper end of the operating)` rod 38 as well' as the piston link 37 extends above the top of the container body 14C into the lowerl part of the housing 19. Theslidable openl ating. rod. 38 is provided with a guide tube lllforniing a liquid tight sleeve which at its upper end is somewhat above the upper end oli the container body 14 and which at its lower end screws with a sealing lit into the container bottom 3, which it is shown nassing through and forming a rod guide therein (Fig. It may be noted that the side of the hollow standard@ adjacent to its base l and, in line below the spout 3l is provided with a drip trough 4l from which any drinpings may drain into the casing andV be caught by the money pan 7 trom which they will4 quickly and harmlessly evaporate.
In the embodiment of the invention shown thepiston 33 is normally at its lowermost position in' the cylinder d tion of the machineis lifted ou of the` inder and is again returned in its i stroke to its lowermost normal position, thus performing a single complete recipi'ocaticn foreach time the machine is operated. Thus the sliding operating rod-*38 ymay termet a lift rod since it iirst raises the piston 33 r before itimparts to this piston its downward as will delivery stroke. The portion ofk the lift rod' 38 which. extendsbelow the container bottom 3 and. the lower end of theguide sleeve 40 passes through and is slidably guided in a bearing provided by they inner frame part or mechanism frameand this rod normally projects freely downwardfbelow this bearing to an extent substantially equal to or a. little greater' than the extent of its sliding movement and terminates in a rounded lower end. T his litt rod 38 is provided with a stop pin l2 which limits its downward movement by abutting againstA the top of the bearing 'formed by the frame part 10. Other stop means for this lift rod will hereinafter appear. Above this stop pin there is a washer 3a-iid on the litt rod 38 interposed between; this washer and the lower end of the guidey sleeve 40 there is a rather strong coiled. thrustA spring Ll-t. lt will now be clear that iii the operating rod 38 is lifted and then released the spring le will return this rod to its lowermost position and. thereby impart aA deliv-v ery stroke toY the piston 33. Thelift rod 38 andL its guide sleeve l0 maybeot brass.
A rockingoperatlng lever has a camy toe which enga-ges the rounded lower end of the lift rod 3,8.k Forwa-rdly fromI the lower end' portion of the lift rod 38,*this operating lever 45 is pivoted on a pin 46 which is carried by a pair of spaced forwardly'projecting ribs formed on the inner frame piece l0, the lever l5 being guided between these ribsas is cleari ly shown in the drawings. `Above and forwardly from its pivot pin 46 theV operating lever ll'is provided with al relatively short tail arm'by which this lever is stopped against the lower side of the indicator trame 12, as shown in Figs. 3, 8 and 10, which thereby-also forms a further stop for the'lift rod 38 against the downward thrust of its spring-44. The operating lever 45, hardened steel stamping, is ot'a flat substantially triangular shape so ythat virtually or in f invention is concerned, any suitable manul ally operable device may be provided for thus actuating or rocking the operating lever 45, such for example as a-usual simple form of plunger projecting from the front of the machine, or by means lor a simple rocking actuating lever provided with a suitable handle at the outside of the machine. However, in the more desirable embodiment of which desirably is al the invention shown, the manually operable device for actuating the rocking operating lever is coin controlled. These coin controlled parts of the operating mechanism will bc described somewhat farther along, since at this point it is thought desirable to describe the mechanism of the hereinbefore noted indicating device which is employed in carrying out'the invention for giving at any time a visual indication of the number of delivery operations to which the machine has been subjected. Such indicator may be considerer, constituting a simplified form of cash register which will indicate thenumber of sales which have been made, and correspondingly of coursethe amount of cash which has been, oi' which should have been, tflren in, regardless of whether or not the delivery operations of thcinachine are controlled by the deposit or insertion of a coin therein.
The indicator mechanism will now be described. A circular window opening is provided in the front and near the top of the hollow standard 2 and is closed by a glass plate 47, held in place by means of a bezel ring` 48, which is flanged inwardly over the front of the glass and flanged outwardly at the inner side of the wall of the standard. At its front the indicator frame 12 has a rather `deep flange which fits up against the edge of the glass 47 and its bezel ring` 48. rl`he eX- posed front surface of the front plate of thisl indicator frame 12 forms a dial, which in the particular construction shown in the drawings is graduated or calibrated in units running from one to one hundred, every tenth unit being indicated by a longer calibration mark and by a single numeral, running from one t0 nine. excepting at the combined starting and Vending` point at the top, which is left blank.
A large or long indicating hand 49 moves sten by step over the dial for giving unit indications, thus moving` one step or unit indication at each oneration of the machine, so that thereby obviously this long outer or forward hand 49 will directly indicate or count the operations of the machine unit by unit from one to one hundred. At the rear of the long hand 49 is a short or medium length intermediate hand 50. At each actuation of the machine. this medium hand 50 moves angularly over only one-tenth of the dist-ance covered by the units hand 49. Thus when the units hand 49 .has made one rotation. to give an indication of one hundred, then the medium hand 50 will have covered teu unit spaces and will stand at the numeral 1 on the dial, thereby also indicating one huncred. according to this hand 50. After this. for succeeding operations of the machine, these two hands 49 and 50 are to be read together. For example, when the unit hand has moved again over the first ten units indication and reached the numeral `dium hand 50v reaches the numeral 9, it will indicate 900. rl`h1s medium length hand 50 is therefore a hundreds hand. lnward from the intermediate medium length hundreds hand 50, there is small or short hand 5l, which is a thousands hand. by reason of the fact theJr in its movement it covers one-tenth 'ular distance of the medium length or hundreds hand 50, correspondin lv covers one one-thousandth of the angltance covered by the units hand 49. rllhus when this thousands hand 5,1 stands at the numeral 1 on the dial. it will. indicate one thousand. lt will thus be readily understood that by reading the dial `.idi cations of the three hands together, unit indications up to 9.999 may be determined, which will then be 51 will now be described. All of these hands are in axial alignment with their common aXis at the center of the dial. rlhe units hand 49 is carried upon the forward end of a shaft 52 which extends to the rear through the dial plate of the indicator frame 12 and at its rear end is journaled in a bearing' provided on the mechanism fra-ine 10. rlhis shaft 52 rotatably passes through and projects at both of its ends beyond an intermediate sleeve 53 which passes through the dial plate and at its forward end carries themedium length intermediate hundreds hand 50. rlFhis intermediate sleeve 58 rotatablyv passes through and projects at both of its ends beyond a shorter outer sleeve 54 which is joui'naled directly in the dial plate of the indicator frame 12 and at its forward end carries the short or thousands hand 5l.
' A large spur gear 55 is fixed on the units hand shaft 59. adjacent to the front side of its bearing in the mechanism frame This gear 55 forms a part of the operating mechanism for driving` the entire indicator mechanism, which will be presently descr-il od. lt may be noted, however, that this dri ing devicehfor Ythe indicator moves the gear 55 for- Ward stepy by step to the extent of one units indication of the units hand 49, each-timev that th-e hereinbefore described delivery mechanism is operated.
A Transfer vmechanism is provided between the units hand shaft 52 and the hundreds 4This pinion 56 engages with a spur gearV which has., formed 1n the same piece therewith as a hub on its forward side, a spur pinion I58 which engages with ak spur gear 59 fixed upon the rear end of the intermediate sleeve 53 which carries the hundreds indieating hand 50. The pinion 56,y gear .57, pinion 58 and gear 59 constitute continuousv'ly engaged transfermeans from the units indicating 'shaft 52 to the hundreds indicating 4sleeve 53, the ratio of which is as ten to one, that is to say, it will require ten rotationsof the shaft 52 in order to impart one complete rotation to the sleeve 53.
Similar transfer means are provided from the hundreds indicating sleeve 53 to the thousands sleeve 54, comprising a spur pinion 60 in the same .piece with and forming a hiubon the forward side of the gear 59, engagingvwith a spur gear 61 Acarrying on its forward side a spur .pinion 62 forming a hub thereon in the same piece therewith and which is in engagement with a spur gear 63' which 'is fixed upon therear end of the short outer sleeve 54 which carries the thousands indicating hand l. The ratio of this continuously engaged transfer gearing from the intermediate sleeve 53 to the louter sleeve 54 is also ten to one.
Thus it will be seen that the comparative extent of angular v'movement between the 4units*indicating hand 49 and the hundreds indicating hand 50 is as ten to one, and simiV larly between the hundreds indicating hand v and the thousands indicatingfhand'51 the comparative extentof angular movement is :also as ten to one, and that accordingly the comparative extent ofthe angular movement between the units indicating hand'49 and the thousandsindicating hand 51 is as one hundred to one. The two transfer gears 57 and 6l are independently loosely journaled upon a `stud shaft '64 which at kits forward' end is rigidly fixed .the` dial plate of the indi-` cator frame 12, the -rearmost transfer gear 57 being positioned on the shaft -by the -f'ront face of 'th-e contiguous drive gea-r 55.
The large drive gear `is continuouslyengaged with and is driven by a pinion 65 which .formed in the saine piece and asa hub 'on' the forward side of a ratchet vwheel 66. This ratchet vwheel 66 with its pinion 65.. is journaled on the middle portionof a shaft 67, the rear end of which enters themechanism frame l0 and `the forward end kof which enters the rear end yof al boss 'formedonth'e indicator frame `12,*so that this ratchet wheel with its vpinion is .rotatively confined Ibetween these two frames, with the upper portion fof the ratchet wheeljust at the reargof thelower portion the drive gear 55.
it will be noted that this ratchet wheelfshaft 6l" is located belowand considerablylto the left side of the gearshaftor units hand shaft 52 so that the toothed periphery of 4the ratchet 66 is j ust at the left of a vertical-,plane t passing throrwh the axis of the. shaft 52.
The ratio ofv drive foreach tooth, or from tooth to tooth, of the ratchet wheel 66 vto the units indicating shaft 52 is as one hundred to one. rllhat is tofsay, each time the ratchet wheel 66 movesover lthe angular distance between two of its teeth, the units lindicating hand 49 will move over a singleunits. indication on the dial. For example, the ratchet wheel 66 mayV have twenty-five ratchetA teeth, itsl pinion 65 may havev twelve teeth andthe drive gear 55 may have i fortyfei-ght teeth. lt might be noted that this ratchet wheel together with all of lthe above described 4gear wheels in the indicator mechanism may conveniently be Zinc `die-castings.
l The device by which the ratchet wheel 66 1s driven or actuatedstep by step one tooth at a time vfor each operation of the above de scribed delivery mechanism will now be described. 'Thisratchet wheel 66 is provided with a holding pawl 68, shown as in the form of a bent leaf spring the remote end ofl which is provided with an eye which 'fits over an anchor pin 69, which may be cast'upon the wall of the mechanism frame 10 which extends just at the rear of the ratchet wheel `66. This springholdingpawl 68 isprevented Vfrom rotating on its anchor pin 69 by means of a holding pin 70 which at its rear. end isy fixed in the mechanism frame lO and thefforwa-rdly projecting yend portion of which vis split to form a slot whichreceives the spring pawl 68 at an intermediate point thereonsuitably spaced from the anchor pin 69, as is mostlpclearly shown in Fig, 1l; The free end of this spring lpawl 68 engages between two of the teetliof the ratchet wheel 66 for norinally holding'V this wheel stationary while at j the same time providing for its rotative move-ment in one direction only when actuat ing'force is applied thereto. VIn the construction shown,the direction of rotation ofthis ratchet wheel '66 is counter-clockwise fas viewed from theA front, vso that thereby its toothed periphery vat the right yside off l its shaft 67 will move upwardly.'
A spring-pressed pawl-'carryingoperating .lever 7l for the .ratchet wheel-'66 is pivoted 'iii on the front and near the lower right hand corner of the mechanism frame l0 on a pivot stud 72 which may be castupon this frame piece. This indicator operating lever 7l, which may be a flat steel stamping, is straight along its lower edge and extends to the left in the form of an arm, the free end portion of which overlies the slot formed between the guide ribs on the frame piece l0 for the operating lever 45, which is a part of the ydelivery mechanism of the machine. It will be noted that flanges or webs are formed on the frame piece vl0 at opposite sides of the upper edges of the guide ribs and that the slot for accommodating the operating lever 45 extends upwardly above these flanged ribs into the uprightvportion of the frame piece l0 at the back of the ratchet-operating lever 7l.
This ratchet lever 7l is in general of substantially triangular shape, thereby to providev thereon an upper arm which extends angularly inward. This ratchet lever 7l is vrovided with a fairly strong return spring 3, which is a coiled compression spring en Agaging over a small lug formed on the upper arm of this lever 7l and at its other end this spring 73 is seated in a socket-forming projection 7 4 on the front face of the frame piece 10. The ratchet-.operating lever 7l, which is a pawl lever, carries a spring driving pawl 75, the construction of which per se may be the same as that of the holding pawl 68. The right or shank end portion of this sprin pawl, which carries an `eye at its end, is anc iored in a slot cut into the pawl lever 71 from its left hand end, and from the point Where this flat spring pawl 7 5 emerges from this slot the spring pawl, by reason of a bend therein, projects inwardly and upwardly with'its free end normally in engagement between two of the teeth of the ratchet wheel 66 at the right of the periphery of the latter. n V Y When the pawl-carryin g lever 7l is rocked upwardly its spring `pawl 75 will impart rotative movement to Vthe ratchet wheel 66 and when this pawl-operating lever` 7l is released it will be returned to its normal position `shown in the drawings by its spring 7 3, which is stronger than thespring pawl 7 5, which accordingly will be moved over the teeth of the ratchet wheel v66, the latter being held against reverse rotation by the holding pawl 68. In the operation of the indicator device, this operating lever 7l will thusl be lifted the correct distance for rotating the ratchet wheel to the extent of a single tooth movement or step, the return spring 73 then acting t0 reset the' indicator-operating lever 7l audits spring drive pawl 75 to normal position, for a subsequent operation. In the embodiment of the invention shown in the drawings, this indicator-operating lever 7l will be thus lifted by the upper edge portion of the underlying operating lever 45-each time Lacasse this latter lever is operated for effecting'a delivery of a predetermined measured quantity of the liquid, as hereinbefore described.
The manually operable device for actuating the operating lever Li5 remains to be described, and in the embodiment of the invention shown in the drawings this i`s a coin controlled device, by reason of which the hereinbefore described delivery mechanism or dispensing mechanism is normally inoperable, the manually operable operating device or driving device being made effective for this purpose bythe insertion of a proper-coin. These `coin controlled parts of the complete operating mechanism of the illustrated coin controlled vending machine will now be described.
Near its upper end the front door'piece or plate 4L is provided with an outer recess 76 which forms the entrance way for a coin. This entrace way 76 is vertically of a flaring triangular shape, as shown in Figs. 3 and 8, and has its upwardly and inwardly inclined bottom wall convexly curved to fit the lower edge of a proper coin while it is open freely outwardly with a vilat downwardly and inwardly inclined upper wall for guiding the flat side of the coin. The coin is thence guided downwardly at its edges in a coin slot 7 which at the front and in the lower parts thereof is in part formed by the inner inwardly and downwardly inclined flat end surface of a lug 7 8 formed on the inner side of the door plate 4 below the coin entrance 7 6. This colin slot 77 at its upper and inner part is also in part formed by means of an inner coin guide 79 which is in the form of a short flat bar notched at the middle on its lower edge and at its opposite ends rigidly secured in place on the inner side of the door plate l by means of a pair of screws 80, one of which ap ears in Fig. l0.
n operating handle 8l,which maybeazine die-casting, is shown at the right side of the Vmachine just above the base l as an upstanding lever arm to be pushed rearwardly and downwardly. This handle lever 8l has a hub portion 82 which is journaled in a bearing provided in the wall ef the standard 2. The notched and squared end portion of a handle shaft 83 is cast as an insert into the hub 82 and adjacent end of the handle lever 81, whereby the handle 8l and its shaft 88, which may be of steel, are rigidly and firmly secured together. The other end of this handle shaft k83 is journaled in a bearing formed on the opposite wall of the standard 2. llVithin the hollow standard 2 the handle shaft 88 carries a coin carrier 84 through the lower end of which it passes and in which this shaft is removably fixed. This coin carrier 84 is in general of Vsubstantially an inverted U shape as probably appears most clearly in Fig. 7 with the handle shaft 83 passing through the lower ends of its arms, so that this coin carrier 84 in general forms an upstanding lever which in its normal position projects upward ly at a forward inclination as shown in Figs. 3 and 8.
rlhe coin carrier 84 at the lower ends of its spaced arms is shown as provided with hub portions the ends of which fit up against the inner sides of the opposite walls ofthe standvle ard 2 surrounding the handle shaft 83. vThe coin carrier 84 is firmly and rigidly secured to this handle shaft 88 by reason of the squared end portion of the shaft adjacent to the handle hub 82 fitting snugly in a square hole through thefadjacent coin carrier hub end, the handle shaft 83 being anchored to this hub end of the coin carrier by means of-a screw 85 the inner end of which engages in a recess 1n the squared portion of the handle shaft as kshown in Figs. 2 and 7, Vso that thereby the coin carrier 84 and the handle mal position the coin carrier 84 will be stopped by a pair of/rear oppositely opposed stop lugs 86 thereon abutting against the lowervsides of lateral forwardly projecting shoulders formed on the lower part of the bracket member 8, as shown. in Figs. 3, 8, 9 and 10. The coin carrier 84 at the left side thereof is provided with a downwardly projecting tail arm 87 t0 the e-nd of which there is connected the forward end of a coiled retractile return spring 88 for thecoin carrier 84, the other end of this spring being an-v chored to the adjacent wall of the standard 2 by means of a screw 89, as shown more particularly in Figs. 3 and 8.
rlhe transverse bar of the coin carrier 84 at the top thereof is provided 'on its rear side with a deep and wide transverse notch, forming opposed lateral shoulders, as shown in the drawings, more clearly 1n Fig. 9. These shoulders, adjacent to rbut slightly spaced ,rearwardly from the bottom of the large slot slots or grooves 90 are normally 'in alignf ment with the coin slot 77, so as to receive the nserted coin 91 therefrom. j
The top bar of the coin carrier 84 has Va forwardly extending ledge 92 which is arcuate on its upper surface and which along its upper side margins is provided with apair of arcuate ribs 93,- the Vrear ends of which are in line vwiththe adjacent faces of the coin-receiving slots 90, and the upper arcuate surfaces of which extend forwardly and'v downwardly from the coin lslot77 along the lower correspondingly curved surface of the casinglug 7 8. The purpose of these ribs 93 is to provide a rest for the Vlower edge of a coin should such coin be vinserted through the coin slotl 77 while the coin 'carrier '84 is outof its normal position, that is, when the coin carrier has been rocked rearwardly. This prevents thelugs 86. The forward ends ofthese lug arms Y 94 are connectedtogether by a 'cross piece or bar 95 the upper side of -*which is provided with a coin-guidingsurface 96, this surface from frontto rear forming an arcuate convex curve which is Ythe `same as the arcuate curve of the path oftravel of the coin carrier, this surface 96 also being concavely curvedr from side to side or laterally to the arcuate' contour ofthe edge of the coin. This coin-guiding and supporting surface 96 extends across from the front to the rear of the top of the cross bar 95.
The rear side of this cross har 95 forms a substantially vertical surface which is sul stantially in line with the aXis of the handle shaft or coin carrier'shaft 83, while the forward sideofthis cross vbar together with` its coin-guiding surface 96 is somewhat forward of the radially aligned coin-insertion slot 77 and fthe coin-receiving slots 90 in the coin carrier-84 when the latter yisin its normal position shown in the drawings.
hus an inaio serted coinsuch as the coin 91 in the coin carrv'rier slots 90 will rest at its lower edgeV upon and be supported by the --curved surface 9G von the cross bar 95, which is cast in the same piece with the bracket member 8. When the coin carrier 84 has been rocked to itsrearward position, the coin 91 will pass beyond the end of the coin-supporting surface 96 and beyond the rear flat face of the bar 95, and' will accordingly be free to drop into the bottom of the casing where it will be received in the money pan 7 f f It will be noted from the drawings, lparticularly Figs. 8 and 10, that the hereinbef'o're described operating leverl 45 has thereon a rounded downward projection or lug 97 which is just at .the front of and in the path `of rearward movement ofthe upper edge por- V tion of the coin 91. Therefore, if the coin carrier 84 is rocked while it carries a coin,
lthe exception that the pivot hole fo the coin carried thereby will rock the operating lever 45 in the mann-er hereinbefore described, for edecting the delivery of a pre determined measured quantity of the liquid. When the coin carrier carries no coin, it is obvious that it may rock freely back and forth without effecting any result. The coin 91 merely forms a temporary extension of the length of the lever arm formed by the coinv carrier 84 and is then released from the coin carrier in the manner above noted. When the operating lever 45 ias been thus rocked to its operated position, the resulting angularly inclined position of its lug 97 together with the rounded contour of this lug will cause this lug to have a cam action upon the upper edge of the coin in the coin carrier by reason of which the coin is pushed downwardly, which facilitates the quiclr release and downwarddropping of the coin 91, as will be readily understood.
It is important that the coin carrier 84 when itcarries a coin should. be compelled to move completely to its rearward position for discharging the coin without .permitting it to return from any intermediate position to or towards its normal position in which it is shown in the drawings. Otherwise it is obvious that the coin carrier could be rocked back and forth to and from an intermediate position and unlimitedquantities of the liquid thereby obtained by the use of only a single coin. Accordingly, in order to prevent this, a pair of forwardly extending coin ratchetpawls 98 and 99 are located one at each side of the lower portion of the operating lever 45,. and at the rear are pivoted on a pin. 100 which extends between a pair of upstanding lugs 101 on the top of the bracket qmember 8, a spacing collar 102 (Fig. 9) beingl provided on the pivot pin 100 between these ratchet pawls. j
Each of these coin ratchet pawls 98 and. 99 is provided at its rear or pivoted end with a tail arm whi-ch projects downwardly Vbetweenthe casing wall of the standard 2 and the rear face of the forwardly offsetupper portion of the bracket member 8, each of these tail arms being urged rearwardly by a coiled'thrust spring` 103 which is seated in a socket provi ded in the back of the bracket 8. This bracket below and forwardly from the pawl pivot pin 100 forms a stop shoulder for both. of these coin ratchet pawls against which they are normally pressed by their springs 103, each of these pawls 98 and 99, however, acting independently of the other.
These two ratchetpawls 98 and 99, wnich may be steel stamping-s, are both ali' 1,.
tne pivot in 100 `in the left hand ratchet pawi locatedfarther forwardly in the pawl arm than is the pivot hole in the right hand ratchet pawl 98 (Figs-8, 9 and 10). YThe right handA ratchetpaw'l 98 projects wardly and terminates in a rounded end closely adjacent to the rear face of and near the upper edge of the coin 91 in the coin carrier (Fig. 8), while the forward end of the similarly shaped. left hand ratchet pawl V99 is a little farther to the rear (Fig. 10).
These pawls 98 and 99 each has a smooth shank portion adjacent to its pivot pin 100 after which for the rest of its length out to its forward end it is provided on its lower edge with a series of ratchet teeth the front faces of which incline rearwardly while the rear faces of these teeth are abrupt, the notches provided between these teeth being adapted to receive into them the upper edge of the coin 91 as it is moved forward by the coin carrier. lt is to be noted that the ratchet teeth of these respective pawlsalternate with each other, that is to say, the pawl teeth in one of the ratchet pawls come even with or opposite to the notches between the pawl teeth in the other ratchet pawl. Thus when the coin carrier 84 carrying a coin 91 is rocked rearwardly, the upper edge of this coin will engage alternately with the teeth of the respective coin ratchet pawls 98 and 99, thereby cutting' in half the amount of lost motion in the return movement of the coin carrier with the coin, before such return movement is stopped by a tooth of one of the ratchet pawls. This arrangement renders it impossible to obtain more of the liquid than has been paid for. It also assures the delivery of a uniform measured quantity of the liquid at each successive operation of the machine. ln this connection, vit will be noted as obvious that the homonologue of this feature could. also as well be embodied in a substantially similar dispensing' device withoutcoin control, for similarly assuring successive uniform deliveries. y
The hereinbefore mentioned notch in the lower edge of the coin guide 79 is to provide clearance for the lug end 97 of the operating lever V45 and similarly for the forward ends los of the'coin ratchet pawls 98 and 99, asbwill be. clear from Figs. 3, 8 and 10, so that these parts may come close up to the coin 91. lt will be noted that the forward edge of the operating lever 45 near its lower end lug 97 is provided with a rounded projection by which in its return movement this operating lever will be stopped against the upper portion of the coin guide 7 9, additionally to the above notedstop provided by its top projec-V tion against the lower side of the indicator frame 12. Vf hen the coin drops from. the coin carrier it will strike a. bell 104 for announcing to the customer that the machine has been fully operated.
lt isthought that the operation of all of theparts and features of the vending machine have been fully described in connection with the description of the construction and that therefore there is nothing which need be acne-din uns respect. c vending-machines constructed 'substantially fas f shown 'in the drawings fand above 'describedhave Vbeen found Ito .operate'successfully,'substantially in the manner hereinbefore described. 4
