Patented Aug. 25, 1908;

To all whom ci may concern:

Be it known that we, WILLIAMC. MAYo and JOHN HoULEiiAN, citizens of the United in the county of El Paso, State of Texas have invented a new and useful Liquid-Dispensing Apparatus, of `which the following is a specification'.

This invention has reference to improvements in liquid dispensing apparatus, and its object is to provide a means whereby beverages or other liquids may be obtained from customer on the depositionl in the apparatus of a coin of proper value.

The present invention has moreparticulai` l reference Ato the means whereby# the liquid may be dispensed after havingbeen released from a normally looked or inoperative condition by the introduction into the apparatus of a coin of proper value.-

The mechanism whereby the introduced coin operates to release or unlock the apparatus to o eration forms the subject-matter of our app ication No. 355,457 iiled February 2, 1907, for liquid dispensing apparatus, of which the present case is a division.

The present invention comprises means whereby, after the apparatus has been irnlockedby the introduced coin, liquid may be ejected from a suitable container in predetermined quantities on the manipulation of the apparatus through external means under the control of a customer.

Since one of the purposes of the invention `is the dispensing of beveragesthe invention further comprises means for providing a customer with a clean glass or other liquid receptacle, and it also comprises means whereby glasses that have been used by previous The' invention will be fullyfu'n'derstood from the following detailed descript-ion,.taken 'in yconnection with the accompanying draw-I ings forming part of vthis ,speciii'catiom in .A y I p which -extendsthroughA the piston and'is operation; ,Fig 2 is a similar view of the portion of the m'achinecontain-ing'-the coin-opercustomers` may be automatically cleansed.

the machine in the act v17 normally against its seat.

Figure 1 yis a central verticalsectionrof the -y improved liquid dispensing machine, with'l and with thel ated mechanism, and showing another phase of the operation of the machine; Fig. 3 is a cross section on the line of Fig. 1 Fig. 4 is a cross section on the line y-y of Fig. 1; Fig. 5 is a section of the coin conduit on the line z-z of'Fig. 1; Fig. 6 is a detail view of the operating pinion; Fig. 7 is a detail view, partly in section, showing a portion of the operating mechanism for ropelling the turntable carrying the liqui -receiving receptacles; and Fig. 8 isa detail view of the coin engaging end of the operatinglever handle section.

Referring to the drawings, there isshown a main casing 1 of cylindrical shape, the bottoni of which is supported upon an foot 2 having formed thereon so as to surround the base an annular trough 3 designed to receive waste liquid which will be ermitted to escape through a suitable ori ce, not shown. In thev bottom of the casing 1 and concentric therewith is a pump cylinder 4 secured to the casing by screws 5, or'otherwise, and this pump cylinder has formed in one side a conduit 6 which communicates with the interior of the pump c linder through an opening 7 at the lower en thereoi. This conduit 6 is continued up above thepum cylinder and there carries a valve 8 contro ed by a spring 9, and the 'top of the conduit is closed by a screw-cap 1() which also serves to confine the valve and spring in the conduit. Above the valve-seat the conduit 6 communicates with a spout 11 screwed through the side of the casing into a boss 12 formed on the side ofu the conduit 6.

Within the pump cylinder 4 there is a piston 13 provided with suitable; packing rings seat formed at the lower end of 'the passage 15. The stem of the valve 1,6 is guided by a Vbracket 18, andra head 20L formed on the valve stem serves to maintain the valve head The piston is carried'. on the lower1 end-lof a pistonrod2 1 there threaded :to receive a nut 22 which..

:servesto 'clainpthe piston iiri'nlyto "a flange 23 Jformed onfthe piston-rod21 nearits lower and. The casing l is ydesigned to formareiptacle fortheliquidto be dispens'egiLand-also .I a nut formed in said rack bar.

for the coin-controlled operating mechanismA `for the machine. To se arate the casing into a lower compartment or theliquid and an upper compartment for the coin-controlled 5 mechanism, the casing is divided into two parts, the upper part having its lower end closed by a iaphragmx24 providedI with an annular 4flange 25 extending below said upper p part of the casing and there threaded so as \to engage threads on the upper inner edge of the lower or li uid-receiving portion of the casing. This t readed connection is indicated at 26. In'order that the mechanism in the upper compartment ofthe casing may be readily accessible, the diaphragm 24 is heldremovablyl therein by screws 27, or otherwise. l

At the center the diaphragm 24 is Jformed ywith aboss 28 through which extends the piston-rod 21, and above this boss the pistonrod projects upwardly into the upperl chamber of the casing and is there rovided with rack teeth 29 for a pur ose w ich will hereinafter appear. It wil now be seen that if the piston be raised from the lowermost 'osition indicated in Fig. 1, li uid contained) in the lower compartment of t e casing and at such a level as to lill the ump cylinder 4, will flow through theopening and by the valve head 17 into' the space below the piston, and when the piston is again depressed the valve head 17 will close this opening and the liquid will be forceds up the conduit 6, opening the valve 8 and escaping throu h the spout 11, the pump being of the or Vinary force-pump type. Coming, now, to the mechanism shown'in the upper compartment of the casin it will be seen that the rack I teeth 29 on t e upper end of the pump piston 40 engage a pinion 30 which, in turn, meshes with another rack 31 fast tov-the inside of the casing by means of screws 32 and facing the vrack 29 on the upper end of the piston-rod.

This structure is such that any force applied to the axis. of the pinion 30 to move the same in a vertical plane will, through the coaction of the two racks 29 and 31 and the pinion 30,'cause the rack 29 to travel through twice the distance traveled by the axis of the pinion 30. Thus the pumpV may be operated through the desired range of movement by a movement of the pinion axis through a ath of only half the extent of movement o the pump piston. For the purpose of moving the inion 30 through the desiredrange of trave there is provi ed a lever 33 pivoted coincident with the rack bar 31 by 'a pivot screw 34 entering This lever 33 is perforated coincident with the axis of the pinion 30, as shown at 35, Fig. 4, and through this perforation extends the hub 36 of aA toothed wheel 37, which hub 36 .constitutes `the journal beari'n 'of the pinion 30 and to which the latter is held by a screw 38 and in'- away, as shown at 41,.to exposeratchet teeth f42 formed on said hub 3-6 at the end projecting through the pinion 30. In the path of. the ratchet teeth 42 is a ratchet pawl 43 pivoted at 44 upon said pinion 30 and under the stress of a s ring 45, as indicated in Fig. 6. The en d of tlie lever 33 remote from its pivot point carries a section 46 of the coin conduit, which section 46 is, in one phase of the operation'of the mechanism, coincident with and projecting into another section 47 of the coin conduit formed as a part, and,4 if desired, an 'integral part, of the walls of the upper compartment of the casing 1, and this section 47 Vterminates at the upper end in a coin-receiving opening 48 exterlor to the machine.

Carried by the lever 33 and confined thereto by guide brackets 49-50 is slide bar 51 constrained by a compression spring 52 to normally tend in a direction aWay'froni the pivot point of the lever 33j ,The spring 52 is confined in a recess 53 formed in the inner face of the slide bar 51 and abuts at one end against one wall of this recess and at the other end against a lug 54 formed on the lever 33 and projecting intoA the recess 53. This slide vbar extends to the Vs ection 46 ofthe coin conduit carried by the lever 33 rand is there formed into a head 55 having therein a vertical roove 56 coincident with the coin' 100 channel ormed in the coin conduit section 46. This head 55 is, however, formed with a cam face 57 in the path of the coin, and a recessed portion 58 below the same constitutes a pocket for the coin, as will hereinafter appear. 'The slide bar 51 also carries a block, 59 in,J osition to engage the teeth' of the toothe wheel 37 when this lever has been moved by the spring 52 away from the ivot yso point of the lever 33, the said toothed lockl A also acting' as a stop for liinitingthe movement of the slide bar under the action of the spring 52. 1 vlThe lever 33 has an extension 60 beyond the coin conduit section 46 and there has pivy115 otally secured to it by means ofa screw 61. an arm 62 extending to the exterior of the machine. This arm 62 passes through a boss 63 formed on a sliding cover plate 64 closing a vertical slot 65 formed in the wall ofthecas- 120 ing 1- and constituting a guideway for. the

-Inovement of the arm 62, whereby the latter may have an extended vertical movement but is prevented from lateral movement and,.

in turn, serves at this point to guide the lever 33 of which 'it constitutes an extension .or elongation. The arm 62 is threaded at its outer enfd to receive a ca 66 between which and the outer endof the oss 63-there is confined a spring 6 7. The arm 62 Yalso receives 130 l which 1s fast to the top of the casing.

is also another spring ger 72.'

lby the arm 62.

in a nut formed in itsouter end the shank 68 of a manipulating handle 69 locatedexterior to the machine in convenient position for manipulation by a customer.

The inner end of the arm 62 is formed into a cam head 70 eccentric to thepivotscrew 61,`

and this cam head enters the coin conduit section 46 through a slot 71` formed therein opposite the head 55 formed on the slide bar 51. The arm 62 has a limited movement around the pivot screw 61 jdetermined by a slotted or hooked finger 72 formed on said arm and engaging a lug 73 formed on said coin conduit section 46 in the path of said iin- Connected to the arm 62 within the casing There 75 connected at one end to the lever 33 and at the other end to the upper end of 'the piston-rod 21.

The normal position of the parts is shown in Fig. 1. That is, the pump piston is at the lowermost point of vits travel and the lever 33 has vmoved downward until stopped by the engagement of the lug 73 with the diaphragm 24, while the spring 74, acting on the arm 62, maintains it in a slightlyelevated position a little above the lower edge of the slot 65, withy the cam head 70 projecting into the coin conduit section 46 oppositeA the head 55 on the slide bar 51, the two parts 55 and 70 coacting to restrict the width of the coin conduit at this point. Now, if a coin be dropped through the opening 48, it will gravitate to this restricted portion of, the coin conduit,

on the diaphragm 24, and when the parts are shown in Fig. 1 this stop 76 enters the lower end of the section 46 of the coin conduit suliciently to hold the coin in line with the recess 58 in the head formed on the end of the slide bar 51. Now, if the handle 69 be moved upward bythe action of the in the position 'spring 74 and by the hand of a customer, the cam head 70 will again enter the coin conduit section 46 and engage the coin, forcing 1t against its seat on ,the head 55 and ultimately causing. the bar 51 to be movedlongitudinally to a sufficient extent to carry the toothed lug 59 out of engagement with the toothed wheel 37. The pinion 30 is-now unlocked and the handle 69 may beraised to' the full extent of its travel and thus, through the action ofthe fixed rack 31 and the pinion 30, raise the piston-rod 21 and the piston 13 to the upwardlimitoftheir movement, as shown in Fig. 2, .this upward limitof travel being determined bythe position of lthe, upper edge of the slot 65 which. is then engaged The customer now presses down upon the handle 69 and because of the wmovable section of the coin conduit.

there is a spring 74, the other end of resistance of the liquid, meantime iowed throughthe valve in the iston to the under side of the latter, the rst downward movement of the handle will cause the arm 62 to turn on its pivot and carry the cam head 70 away from the coin, thus permitting the coin to fall from out rltple e slide bar 51 now returns to the first position under the action of the spring 52 and the toothedY block 59 engages and locks the toothed wheel 137 But the pinion l30 is still free to move upon its axis since the pawl 43, which holds the pinion against movement on the hubf36, is inactive to the movement of the pinion in a direction to lower the piston. However, as soon as been lowered to the position shown in Fig. 1, the pawl 43 and ratchet teeth 42 coact with the toothed wheel 37 and toothed block 59 to ei'lectually lock this pinionagainst return ymovement and so lock theentire structure against further manipulationuntil another coin of the proper denomination has been inserted.

In the operation thus far described it'has been assumed that the user is supplied with a suitable receptacle -or through the spout 11. But the invention contemplates means lwhereby clean glasses, or other suitable receptacles, may be carried by the machine' for. the convenience of theA user. For this purpose there is formed on or secured to the lower portion of the casing 1 an annular flange 77 between whichand a shoulder 78 higher up lon the casin mounted an annular casting 79 made hello as shown, for lightness, and this castingv is formed at its lower end with anannular, horizontally-projecting glass-carrier 80.. Upon the yupper edge of vthe casting 79 there is formed an annular ledge 81 carrying an annular series-of ratchet teeth 82, the purpose of which latter will ybe hereinafter described. The iange 77 carries afnurnber of equi-distantly spaced hollow u rights 83, each having a number of upwar ly-projecting nozzles 84, -and, the top of each upright terminates in a pin 85 -upon which is hung a glass tumbler 86 bottom upward, the lower edge of the glass hanging close to the upper face of the glass-carrie;- 80 within an upturned rim 87 formed on the edge of the glasscarrier. .The interiorof each of the hollow uprights 83 communicates with a duct 88 extending throughthe vbase of .the glasscarrier to a point above the flange 77, and in this flange 77 there is Jformed a passageway 89, open on its upper edge so as to be in communication with the inner ends of theducts 88. The `passageway 89 extends through but a portion of the circumference of the ange 77, say to theextent of about ninety degrees. The ducts 8 8 will therefore 'be in communication with this passageway which has inthe t'hc handle 69 has again the liquid ejected e n tion with said passageway 89 the water isl fast in any suitable manner to the casing, and

92'and link 93 the-lower end 95 of the pawl 94 will be sufhcient to move the glass-carrier a moreor less tangentially and produce a swirl of the water which is very efficient in cleansf away in any suitable manner, as by means of glasses carried thereby.

through but one-quarter of the revolution of the glass-carrier, which latter, in the practical operation of themachine, is made to travel entirely around its seat on the flange 7 7 Water is conveyed lto the passageway 89 from a'source of sup ly, not shown, and when one or more of the ucts 88 is in communicaconveyed through the hollow uprights 83 and forced through the nozzles 84 against the sides of the glass tumbler's. These nozzles 84 are iven a slight twist, so that the water jets wilI strike the inner walls of the tumblers ing the inside ofrthe glasses. The water used for washing the glasses falls on tothe bottom of the lglass-conveyer', which is purposely madeslightly inclined toward the axis of the conveyor, and a number of passages 90 are provided to convey the waste water into the trough?) from which lit may be conveyed a waste ipe, which, however, isnot shown. The g ass-carrier is covered by a hood 91,

which extends, around the said glass carrier except adjacent to the spout `11, so that the glasses are hidden from view while being cleansed and only the one about to-be usedis within the reach of the customer.

l The passageway 89 is made to extend through only about a quadrant so that the glasses will have time to drain and dry before they are brought into reach ofthe customer. In order to prevent the escape ofn water between the passageway 89 and the edges of the glass-carrier, the meeting edges of the glass-carrier and the flange 77 may be ground to produce a watertight joint.

In' order to provide for the rotation of the glass-carrier, the lever 33 is formed with a short arm 92 to which is secured a link 93 carrying a pendent awl 94, the lower end of. which is formed with) a tooth 95 engaging the rack teeth 82 on the ledge 81 before referred to. The awl 94 passes through and is guidedin .t e u per wall of the hood 91, and this portion of t e structure is protected by a casing 96 fast to the casing 1 and the hood 9 1 as indicated in Fig. l. Now, when the lever 3.3.is moved to raise the piston 13 the outer ed of the arm`92 is depressed and through t e link 9 3 depresses the pawl 94, which, in itsl normal position, restsbehinda tooth 82 at a slight angle to the vertical, so that as a res`ult of the vdownward movement of the arm willr be forced in a direction to. rotate thev glass-carrier upon a verticalaxis., and the parts are so proportioned that this rotationdistance equal to the distance betweentwo4 It is possible that an unscrupulous customermay endeavor to insert a coin to which a string or wire has been vattached Vfor the i purpose of operating the machine and then withdrawing the coin. To prevent this, the up er-section 47 of the coin conduit is provi ed with a cross vslot 97 in which moves a knife blade 98 'fastto one end 'of a rock-arm 99 pivoted at the other end to the diaphragm 24 and in the path of a lug 100 on the arm 62 l of the manipulating lever, so that as this lever is moved theknife will be forced across the conduit*` and thereby sever any cord or wire which may have been attached to the coin, before the lever vcan be manipulated to cause the machine to expel the liquid.
