CUP DISPENSER.

Application led October 22, 1926. Serial No. 143,340.

' This invention relates to cup dispensers and more particularly a dispenser especially adapted for machine operation for use in automatic machinery, where posit'ivenessv in operation as well as the capacity for'speedy operation. becomes an absolute necessity. y

The present device, although not limited to use in connection with an automatic machine such as a filler and capper, is particularly well adapted to the requirements of a machine of this kind by reason of the fact that it will not, under any circumstances. release more than one cup at a time nor will it dispense a second cup to any stationV of a conveyor. Neitherl will it fail to supply a cup to any station by reason of the cups sticking` to one another. Obviously, a dispenser of this character offers the advantage that there will be no possibility of the machine becoming jammed, which happened whenever aV number of cups were fed to one station ofthe conveyor and fouled with the iilling or capping mechanism or some other part of the machine. Nor can there be a loss of material and consequent messing of the machine by reason of the failure of the dispenser to supply a cup to any particular station of the "conveyor, which sometimes occurr'eo with the ordinary type of cup dispenser' where thecups failed` to droop due to their becoming stuck together inthe stack. n

' A further and important feature of the Vpresent dispenser lies in the fact that the cups are not dropped singly in a way which would permit of their becoming cocked sidewise and fail to arrive in proper position on the conveyor of the automatic machine, but are directed and `guided by moving with the stacl: into position on the conveyor so as to eliminate any uncertainty as to the proper ldisposition of the cup when dispensed. This Vfeature is particularly important where quantityproduction requires speeding up the operation of the Inachiiie to the point where ai many' as t5 cups, or even more. have to be di pei per minute. under which circumances Vthe ordinarv types of cup dispensers t occn found to be impractical and to give serious trouble., y l

yThe novel method of operation just referred to permits of the use of a simple means to strip olf the dispensed cup from the stack in the event there is any tendency for `it rto' adhere,and also enables the use of a novel means' whereby adjustment' may be ymade to adapt the dispenser to operation with cups of slightly different characters. i

v The linvention is illustrated in the accompanying drawings, whereinf Fig. 1 isa front viewof a Iilling and cap-A ping machine equipped with a cup dispenser made in accordance with my invention;

Throughout the views the same reference num eralsl are applied to corresponding parts.

As stated before, the cup dispenser of the' present invention is not limited tof machine operation but may be manually operated, as 1n the case of a vending machine. However,

I prefer to illustrate the same in rconnection with a filling and capping machine as shown in Fig. 1, which corresponds to that shown in my copending application, Serial No. 72.618, filed December 2,1925: lAs stated in. said' application this machine makes what are known as packaged sundaeswhich are individual cups intendedfor delivery to thev ultimate consumer as a handily made-up confection for home or picnic consumption. The cups or other containers used for this purpose are preferably of waxed paper which p are relatively inexpensive and intended to be thrown away after they have served their1v hurpose.

Referring toFig. 1, the cups or other suit'- able containersA lOare fed` one by one from an l upright container 11 into openings 12 provided inthe plates of an endless linked-conveyor or belt 13.Y The latter isfed step by step fromend to end of a frame 111 which constitutes a unitary support for the cup dispenser 15, of which the container 11 forms a part, the cream dispenser 16', and the capping y mechanism and cap ldispenser 17, which comprises an upright container 18 for caps. For the present purposes it will suliice to state that the cups are supplied one by one from the dispenser 15 to the conveyor 13 and pass beneath a rider 19 andby keeping the saine elevated prevent the stoppage oi" the machine, as described iii my copending application above referred to. '.Aiiter passing the rider the next station reached by the cup-is beiieath the lirst et two measuring' cyliifiders 2l) from which a measured amount of sherbetis dispensed into thc cup, in case the .cups 211'@ to be lilled withsherbet and cream. The next station is beneath the second cylinder 2O Jfrom which a measured amount ot crean'i is dispensed siillicient to lill the cup.' The tllled cup aiter leaving the creamv dispenser is closed witha cap by the capping mechanism at 17 and, in the course or several more step by step advances et the conveyor 1,55, enters upon lingers 21 extending toward the nia- ,chine from a ,chute 22. The filled cups ire renioved-itrom the-chute and placed inte .cans

which are removed te a hardening reoiii. The

produetionoif l the .filled cups proceeds at a rapid rate, as many as l5 or more cups being tilted per minute. The motor 23, which provides the power for the driving` oit the cup dispenser, the cream dispenser and the cap feeding and applying mechanism, coniinunic ates .power 'to the main drive slialt 2li.

"llhrough the intermediary oit suitalile cams (not shown), oscillating' 'movement is given a lever 25 at the back of the machine to recipl recate a link 26 to operate the cup dispenser 15. From this point on reference will be had more particularly. to Figs. 2 8, inclusiva-foi' a more detailed discussion el my iin- .proved cup dispenser.

The cup dispenser comprises thc upright container. 11 preferably open on one side so 'l'batthc stack et nested cups 10 will be visible to the operator and he can easily see when thc supply et cups is nearly exhausted. The container 11 is refifeive-d iii a base portion 27 slidably mounted on a paire'tl guide rods 28 tor -nioveinent up and down with respect to the conveyor 13. The baseportion 2"? is also slotted as at 29 to inake the stack of cnps visible to the last. rlhe guide rods 28 vproject vertically and in' parallel relation from a. block `l() secured, as by means of the bolt 31, to the trame 14 oi the machine. A pair et vcup gripping jaws 32 is pivotally mounted on the container base 27 as at 33, tor inovenient indicated by con'iparison oipFigs. 2 and The jaws 32 are contouredas atl-341 to lit nicely about a cup just beneath the rolled riin portion 35 so as to hold tliecup 'firmly and without crushing. rThe jaws Y32 constitute extensions from the bell crank lever portions 3G by means of which they are pivoted to the container base 27. The hell crank lever portions 86 provide arms 37 extending toward eachother, as appears in 241, tobe pivotally connected, as shown atBS with: the link 26, The pivot pin 38 is riveted to one o'l the arms 37 and has capacity for Vsliding motion container base 27 comes into engagement with an elongated head 41 provided on the boit 3,1 and serving as a stop, thc-link 2,6l is lree to nieve with respect to the container hase, as'indicated in Figs. /l and f?. i'ihis v-niovenient of the link with r respect to the iontainer base serves to open and,V close the remain closed until thecontainer arrives at the lower Vend ofvits stroke whereupon the jaws are opened by the 'further movement et' the link 2G with respect to the container. The opening o'l'l the jaws allows the stack .oit

cups to drop so that the lowerinost cup ,enters and seats in the opening` 12 in a linker the conveyor 13. The rim portion 35 seats ontop oft' the link about the opening. asV indicated .in Figi'. 7. In this operation it will be clear that the stack of cups has moved a solid column and pointed the lowerinost cup directly into its opening` inA the conveyor. V he cup was thereby positively directed and guided into place so that there could be no i possibility of its becoming cocked to one, sideV or another, as was the case in other types oi cup dispensers where the cupwas causedto drop an appreciable distance after being re'- leased from the stack. Furthermore, whenV the cup has entered the opening el: the ronveyor it is squared up properly by the weight of the stack ot cups resting thereon. The cup gripping jaws are closed on the commencinent of the upstroke oic the link 26, as indicated in Fig. 8. Thejaws grip the next to the lowerinost cup and raise the stack with it out of the cup that has been dispensed. The 'features next to be described have reference te the provision of novel means whereby it is insured that the cup'dispensedwill notbe picked up with thepstaick on the withdrawal ot' the latter.y clue to the cup sticking orbcing wedged on the stack, and also to the teature whereby the cup dispenserinay be readily adapted to ,operation with cups offslightly but, at the end ,et the downV stroke when the different characters, as for example where the cups to be used are made of paper of somewhat different thickness vwhich might produce avariation in the spacingof the rims B5 ywhen the cups arenested.y

- lwith a lug 45 provided on a plate 46 when in its operative position. The plate '46, as shown in Figs. 68, is held in position with the block 30 by the bolt 3l. The dog 42 is arranged to be movejd to, an out'of the way position when the container arrives at vthe lbottom of its'stroke'so thatthe stack of cups is perfectly free to drop down to position the lowermost cup in the conveyor. provided on tlie'container base 2'( engages the-dog 42, as shown in Fig. 7 and moves the same to an out of the wayposition against the action of the spring 44. However, inimediately upon the raising of the container the plate 47 nieves away from the dog, as shown in 8,' and the4 latter is rmoved out to its operative position in between the lowerniost cup and thev nexty cup just above.

Then, if there is any tendency for the lowermost cup to adheie to the stack and to be raised with it in the raising of the container. the dog 42 will strip'the cup off the stack and retain it in the conveyor, Under ordinary circumstances the dog may not come into play as the lowermost cup will, lof itself, remain on the conveyor when dispensed. However, there are times wlieu the cup, due to a possiblel compression of the stack, has become wedged in the stack and will not become sep# arated so readily in which case the dog will serve the purpose'of forcingtliecujli off the bottoni of the stack. vOftentin'ies the paraffin lcoat-ing on Vthe cups: will cause ythe cups to stick to one another, especially in warm weather and in that case alsothe dog 42 insures the removal ofthe cups one' by one as they are dispensed. The dog is suitliciently close tothe conveyor so thatvthe cup does not have an opportunity to rise very far out of its opening in the conveyor before' it is stripped off the stack. The cups, therefore` drop back easily into place when stripped olf and will notV be cocked up in an improper position. Thus, there is no likelihood of the machine being jammed by a cup fouling with any part of the mechanisml rllie cup gripping jaws 32, it will be clear, operate in a fixed spaced relationship with respect to the lower'end of the container 1l,

A pl ate 47 v particular station.

or more specifically, the lower Vend of the container base 27.' Thus, when the container is in its lowermost position as respects theco'iiveyor the jaws 32 vin opening and closing operate in a predetermined spaced relation vto the conveyor. I, therefore, provide the head portion 4l on the bolt Bl of a proper length to provide for a predetermined clearance between tlie aws and the conveyor in the opening and closing/of the jawsv so as to insure proper gripping engagement of the j jaws with the next .to the' loweriiiost cup of the staclrafterthe stack has been released and is resting onr the coi'iveyor. "Obviously, the

clearanceto be left between thejaws and the y conveyor will depend on what the distance is lbetween the rims of the vcups in the stack. The vdistance between-the rims of the cups in the stack will vary slightly vif the cups are made of thicker or thinner stock. ing the length of the head .4l the container -wiil be'spaced differentlywith respect to the conveyor'when it comes into contact with the head 41 and the cup gripping jaws will accordingly operate closer to'or farther from the conveyor depending on whether the head 4l is shorter or longer. `In this way, it is positivelyinsured that the jaws will pickup all but the bottom cup lofthe stack atr each operation of the dispenser yto and from the conveyor'. Instead of making a variation in the length of the head 4l it is obvious that Y the bolt Sl'inay be provided as an adjustable set screw and having a lock nut to secure the same in its adjusted condition.

lt is believed that the foregoing description makes it clear that the dispenser can never release more than one cup at a time under any circumstances.- Neitheris there A'any possibility of the dispenser failing` to rdeposit a cup to each station. The present dispenser, unlike any other dispenser of which I am aware, will not repeat the dis-v pensing of a cup to any particular station.

.In certain cases, as for Iexan'iple where the Yoperator has stopped the machine to make lsome adjustment or repair and might in so doing turn the'coiiveyor back a step or two,

. the ordinary dispenser under such conditions would dispense a second cup to one or more stations, which would cause a jani if the niachine were allowed to proceed before the operator noticed the trouble and would stop the machine .to remove the surplus cups. vlith the presentdispensei' there is no possibility of dispensing inoi'e than one cup to any Assume, for example, that 'the conveyor is turned back so that a stat-ion containing` a cup is brought beneath.

the dispenser. In that case, when the vdispenser isl lowered the stack is entered iii the cup already dispensed. The' gripping jaws will then pick up all but thelowerinost cup *soV that only one cup will, in anyI event, be

leftin any station of the conveyor. The

elimination of all possibilities of jan'iiiiing arising from the operation of the dispenser makes the present dispenser particularly well suited to use in automatic machinery, espeeially'where a large number of cups have to be handled per unit of time.

It is believed that the foregoing conveys a clear understanding of the objects and possible uses of my invention and wiiile I have illustrated but a single working embodiment itshould be understood that changes might be made in details of construction or arrangement without departing from the spirit and scope of the invention as defined by the appended claims.
