IN, vnssIeNoR To. AMrmICAN LACE PAPERQ WISCONSIN, .A .coRroRATIoN .or WrscoNsm Application .led March 5,

VThis invention relates to improvements in ldrinking cup dispensers. 'Y

:It is theobjectofthe invention to provide Ya novel and simple form of dispenser havling no movingparts and in which a stack of paper cups or like `articles is sup-ported on A.fixed flanges so designed as *to*l provide adequate support for thestaclz, to *permit the Vwithdrawal of individual cups from the bottom of the stack, and to `minimize the resistance to such withdrawal.

There have been numerous attempts to devise dispensers `for paper cups and the like `in which fixed flanges would :take the place of movable escapement mechanisms. It has7 been characteristic of the fixed flange devices-thatrthey have either beeninaccurate in permitting the escape of imore than one'cuprat a time or elsehave afforded so much resistance as 4to be very'diflicult of operation. VThe lpresentinvention 'seeks` to overcome lthese objections :by VKa design `in which Y the dispensing flanges are spaced apart for a distance less than the distance between the marginal bead portionsof the Vcupsto be dispensed and are so arrangedwith referencegto thegenclosing barrel as to provide space into which the distorted'margnal bead portion of the cup may expand during 'its successive clearance of the flange members `which oppose its, discharge.- Since clearance is providedfor but one cup bead at a timefthe device functions accurately in discharging individualV cups and since the cup bead clearsthe projecting flanges successively instead of simultaneouslythe resistance to withdrawal is minimized.V Hence a -device embodying the present invention material fori retaining the .upper :portion cfm thestackjof'cupstobe dispensed. i"

1931. ASerin No. 520,201.

-Like characters throughout'the several lviews.

The v'dispensing` device comprises a sleeve .5 providedI at its rear witha boss 6 havinga parts are identified `bythe reference dovetailed slot at 7 Vto engage a mountingffs plate V8. The intermediate portionlof the slot 7 is deep enough to secure the heads of screws used-to supnortthefmounting plate.

VThe mounting .plate has laterall notches, oney of whichis shown at 9, andvvhich are adapted ed to receive set screws `10 inserted tfromthe sides of boss 6, as shown in dotted lines-in Figure 3. v

The sleeve 5 `is counter fbored to receiveM tube l1 which vissupported on shoulder 12""6 with its interior surface flush. With1thefad- #Tube 511 may glass orfother jacent interior wall 1 ofV tube 5. comprise the usual tubing of Below tube l1 'the `interior fsurface of disp pensingV sleeve '5 tapersvery slightly inwardly,:as'shown at 15, toward'ashoulder '1G-at whichthe transverse dimensionof the interior vbore through sleeve 5 enlarged in a lateraldirection. The diameter `of the sleeve :portion 1'5 immediately aboveshoulder 16 is made to 'correspond closely to the diameter=of the'beads rof'the,

l cups to'be dispensed, thus r'eceivingfthe staekti and permitting it free yaxial movementwhile substantially eliminating possibility of v'lateral movement of lthe lowermost cups.

At the front andrear of the interior lWallf is substantiallyc surfaces ofthe sleeve 5 ijustbelow-shoulderugr '16 are'flanges 17 and 4 18 which project'centrally to materially restrict the internaldiameter of sleeve' from front to rear. These flanges have ybeveled upper surfaces and aref;- very slightly offset in a vertical direction-so that they Will not simultaneously oppose their lmaximumresistance to a given cup which isl being dispensed therefrom. The offset is preferably less than the distance b etween'feiiV corresponding bead portions of consecutive cups in the stack. Below the flanges 17 and 181I the internal'peripheryfof sleeve 5` again becomes" cylindrical .as shown atv20, its diameter" being thesame yas the transverse di-y 100 mension immediately below shoulders 16 at the sides of the device.

When a stack of cups is in the dispenser, the marginal bead portions of the lowermost cup will rest simultaneously on both of the flanges 17 and 18, the offset of flange 17 above flange 18 being insufficient to cause flange 17 to take the entire load. AWhen the operator grasps the lower portion` of the lowermost cup to effect withdrawal thereof from the dispenser the resistance offered to the front and rear portions of the bead of the cup by flanges 17 and 18 causes distortion of the bead portionof the cup whereby its transverse diameter is increased as compared with its diameter from front to'rear. The increase in transverse diameter is accommodated by the enlarged bore 20 below shoulders 16. The shoulders 16 are so located with reference to the height of flanges 17 and 18 as to be adapted to receive only the bead portion of the lowermost cup, thereby preventing more thanone cup from being dispensed; `In this connection it should be noted that the offset of shoulder 18 below shoulder 17 is not essential to the operation of the device but does contribute materially to the smoothness of the operation since, as above noted, the maximum resistance of the shoulders 17 and 18 is consecutive instead of being concurrent.

When one side of the cup passes flange 17 it immediately springs out to its normal circular form, thus relieving the cup distortion at one side. The other' side of the cup is undergoing Van increasing distortion at A`the moment due to flange 18 but immediately afterward this part of the lcup alsoV is relieved and the cup passes freely from the dispenser.

I have found that the freedom of dispensing action can be controlled quite largely by the extent of flanges 17 and 18. If such flanges are of less extent than they are illustrated in Figure 3, the dispenser tends to function inaccurately. If the extent of the flanges is increased they afford an unnecessarily great resistance to the dispensing operation. Preferably they should be slightly less than 90O in extent as shown.

VwWhile I have referred to` cup distortion herein, I wish to make it clear that such distortion as occurs is preferablyvery slight,

the dispenser size being accurately worked `out with reference to accurately sized cups to be dispensed.

I claim:

1. A dispensing device comprising a sleeve having a stack receiving portion` a cup delivering portion of greater diameter than said stacl; receiving portion, circumferentially spacedmeans between said portions adapted toengage thelmarginal bead portion of the lowermost cup of a stack, said sleeve being recessed intermediate said cup engaging means to receive bead portions of a single cup passing said means.

2.
