'our-DfisPENsING MACHINE.

"Application fried october e, 192e. serial No.2 139,793.'

\ This invention relates to dispensingmeans and more particularly to a cup dispensing machine. My invention is intended foriuse in dispensingV cups which are disposed in stacks and `in nested. relation; It am iaivarethat numerous 'machines forI dispensingjcups' arranged in stack and nested relation-have been used, but the machines 4of thislcharacter v l porting and separating the cups or, in some cases, pivoted latchesor equivalent mem-v F bers for this purpose.'` As a generalnrule f the construction ofthe dispensing mechanism is complicated and expensive andv involves an unnecessary number of parts, sothat the likelihood of` bindingor disarrangementl of parts is always tov befeared..z Aside-from.

thefobjections notedthereis, necessarily, a veryv appreciable expense 2 incurred. in the accurate fitting4 and machining bof the vva` rious parts, renderiiig :the 'cost ofthe completed' machine excessive, which Anecessarily results Yin its .use being restricted.

`.In mymachine I Vavoid the, numerous obl, je'ctions above noted regardingthe machines ofthisgeneral typeinowin'vcommon use reducingfthe number of movable parts `to'a minimum` and `having such parts sol constructed and `,related as-:toeliminatei all a probability of t binding orfinaccuraciesvin operation ofthe-dispensing!mechanism; I-

also provide my dispensingmachine ywith a receiving elementA so disposed vasto; re-` ceive .cups dischargedl vertically from the machine, Ythiselenient beingso arranged as to permit ready removal'y ofthe cups' by slight distortion thereof. Injconstructing my machine I have-takeny care-tofhaveall surfacesof the'dispensing mechanism: so,

Thecover is further provided With upwardf i v. lyjextending fingersu Whicharedisposedinf f r circular arrangement and snugly receive the lower'portion of an elongated cylindrical cover or container 9 of glass or other suitable material. The container 9 seats'upon the upperrnd 'of neckx 1, the innerperipheral surface of the container being ush with the inner peripheral,surface of the neck so as to (form a continuation thereot. The cups C to'be dispensed are arranged within the container 9 in a stack and in nested relation. The cups employed are preferably constructed in accordance with the `cupedisclosed in the patent to Ernest R. Huntley ior paper vcup, INo. 1,497,755 issued June 17, .1924, though any L:other suitable or preferred 'torni of paper cup maybe employed. Cup C-is provided at its upper' endfwith-an outwardly turned bead or 'shoulder c* of appreciable thickness or height and the body of the (iup is olt" `frusto-conical shape' being;- inverted or tapering downwardly when the cupsarei supported in the container. The dispensing` mechanism which I employ is so constructed as to'readily enter betweenthe flanges of two adjacent cups lwhen these flanges are disposedclosely adjacent or in contact with each other. I consider' this an importantl feature oie-'my invention permitting` the cups to be nested with the `flanges evthereofv in contact with `eaclrother.` By this arrangement it is possibleto include in asingleist'ack amuch larger `number of cups than'can be done when the cups'ai'e stacked in-t'heJordi-nary` manner now necessaryl in machines aty present commonly "used, in

whichy machines the `cups are so stacked or arranged that the upper endsoi" thecups are spaced a very appreciable distance apartto permit operation 'otthe'separatihg and dispensing. mechanism. lVith the separating and'v dispensing-mechanism which I employ this objection is avoided and a very consider'-v able Isavin'gin space necessary to acconnnodate a stack of cups is effected, which lis'an important consideration. f'

' The base platel2rand the cover member l cooperate to form a housing for reception' of a U'shaped slide `10 which is slidably mount# ed `on"-t'l1e f'upper face of'base plate 2 and confined between this plate and the top 'wall of the cover'so as to be held thereby against all vertical `looseness or play. The arms y11 of this slide are vconfined between the outer flat-surfaces of flattened side portions-1n of neck 1 and-the side wall 5 of cover member 4.' The-cover member and the plate thus 'co-v operate with each other and with the neck to form .guideways for-'the slide andthe arms" thereof and eilectually. prevent looseness or play ofthe slides VVThis is animport-ant fea'- ture inthe construction of my machine as it insures accuracy in operation of the slide and'proper entry of the cup lseparating and dispensing'means between the flanges-of the cups irenderingitf possible to stack the vcups with their' 'ianges c'iclosely adjacent andin contact With each other, as above noted. The front wall 5 also acts as a stop element to limit outward movement ofthe slide 10 which is urged outwardly by an expansion coil spring` 12 seated at its inner end in a recess 13 provided inneck 1.. .The outer 'portion of spring` 1:2isY rseated ina" hollow stud 141 evtendinpl from 'the center of the vbight portion 1150i slide l() yand operatingv through an opening provided through wall 5..fat'r15f"Villienithe slide 1() is in its outer position, the inner ends ot arms' 11 are spaced away trom wall a'oi the housing, this distance being sutlicient to'permit'inward movement of the slide into position to bring,` the biglitportion l210t thereot'vinto con-` ber- 17 is provided with a double point radius i inner portion 171,'the 'apex ot' which is dis posed abovezand'remoteronrtheouter end offmember 16.

which is an important vconsideration in this art.

` y The outlet member is providedv with a depending'arm 18` carrying at its lower end a receiving member or collar 19 which is disposed in concentric relation tothe member '3. The upper inner portion 20 of member 19 is :flared and the'forwardl ends of vthe' arms of `this member are beveledor inclined outwardly and forwardly at 21. The cup discharged through neck 1 and outlet member l 3 is' directed into the member 19vwheie it is f support-ed by means of its shoulder c. This cup `inay be readily removed from member 19 by being raised slightly therein and then moved outwardly tl'irough the space or opening 22 between the ends of the arms of the receiving meinbei'. The flare 20 at the upper end of member 19 serves to direct the cupA into such member and thevincli'ned or beveled surfaces 21 permitl the cup to. be readily withdrawn fromthe receiving member without excessive distortion ofthe cup or danger of injury thereto.

This provides simple and` veflicient means whereby the cups, as they vare dispensed, are Areceived fand. held in position to bereadi-l-y removed fromlth'e machine.
