HOPE ATTORNEY Patented Nov. 4, 1941 UNITED STATES TNT ()FFICE I DISPENSING DEVICE Samuel N. Hope, Wauwatosa, Wis., assignor to Griffith-Hope Company, West Allis, Wis., a cor- The present invention relates to devices for dispensing paper cups and other articles.

It is customary to dispense various kinds of articles, such as paper cups, from a forwardly movable stack or pack, the foremost article thereof being withdrawn as needed. In some instances the successive articles of the stack or pack, especially when disposed in nested relation, tend to cling to each other, such tendency being particularly pronounced in the case of Waxed paper drinking cupsafter exposure to heat.

An object of the invention is to provide an improved dispensing device having simple but effective means for retaining a stack or pack of articles although permitting ready withdrawal of the foremost article and causing release thereof from the succeeding article, notwithstanding possible adhesion between the articles.

Another object is to provide a dispensing device which iscapable ofeconomical manufacture and which is reliable in operation.

A further object is to provide a'dispensing device. which can readily be filled through the dispensing opening of the device.

A still further object is to provide'a dispensing device which will facilitate the, mounting thereon of "a magazine-forming carton or package .containing the, articles.

The invention further consists in the novel features hereinafter described and claimed.

Fig. 18 isa fragmentary detail view'oftl'ie'" In that form of the invention shown in Figs." 1 to 8, I0 designates a tubular casing which c'o'm-" prises a' cylindrical'sheet metal shell 'll of 0- shaped cross-section bridged by a longitudinally member 12; and closed at its rear end by a flanged sheet metal end plate I3, the channel member and end plate being rigidly secured to the shell;

as by spot welding. At its'front end the casing is provided with a sheet metal extension collar 14 spot welded to the shell and channel member.

The casing is suitably supported, preferably inhorizontal' positionwith the channel member uppermost. A flanged wedge plate I5 is rigidly engageable in a mounting bracket l6 secured to the underside of -a horizontal support H, such as' a soda fountain counter, the casing being drawnv m forwardly to a wedging position. v a The casing isadapted to housetherein a succession of articles, which in the presentinstance & tom of the foremost cup projecting from the casing, and the beaded rims of the cups fitting loosely in the cylindrical shell ll. i

i The cups are releasably retainedin the casing by a plurality. of spring-pressed dogs 20 mounted in the shell four peripherally spaced dogs being shown in the present instance. Each dog consists of an elongated block, preferably of metal, extending longitudinally of the casing and having a pair of longitudinally spaced, pointed teeth or projections 2| and 22 which extend respectively through a pair of aligned slots 23 and 24 formed in the shell, there being a fulcrumforming bridge 25 between these slots loosely fitting in a fiat-bottomed notch 26 formed in the dog between the teeth. The dog pivotally bears on the bridge to permit a limited rocking movement of the dog, the opposite ends of the dog having stop projections 21 which are engageable with the outer surface of the'shell beyond the; ends of the slots 23 and 24. The dogs 2|! are held in the slots by a coiled tension spring 28- extending about the shell and fitting in central notches 29 formed in the outer edges of the dogs, the ends of the spring being anchored on hooks 30, Fig. 5, struck up from the flanges of the channel member H2. The spring and dogs are housed in an arcuate sheet metal cover 3| of channel cross-section extending about the shell II and secured thereto by rivets 32. The dogs are preferably symmetrical about a central transverse plane, thus facilitating assembly.

A cup-shaped follower 33 slidably fits in the, shell I and has an end wall bearing on the rim portion of the innermost cup. A spirally wound leaf or ribbon spring 34 has a portion extending in the-channel member l2 and is rigidly secured at its'front end to the extension collar I4, as by a rivet 35. The spirally wound spring extends into the shell and has its outer convolution bearing on the inner side of the end wall of the cup-shaped follower 33, the latter having a notch 36 in its side wall to admit the spring. The spirally coiled'spring tends to roll up toward the open front end of the casing and thus'urges thefollower 33 and the cups |B toward this end. Theflange ofthe' foremost cup, however, engages the teeth 2| of the spring-pressed dogs 20, thus restraining movement of the cups.

When a cup is to be dispensed, it is grasped in the fingers and pulled outwardly, the rim portion of the cup displacing or depressing first the rear teeth 2| and'then the front teeth 22 ofv the dogs 20 and causing the dogsto pivot on the bridges 2.5. the rear teeth 2| of the dogs b'eing thus urged against the second cup in front of its beaded rim Hi to restrain movement of this cup. Continued outward movement of the foremost cub causes the front teeth 22 of the do s to be--' come further depressed against the action of the coiled springs 28. as seen in Fig. '7, the dogs then pivoting on their rear end portions 21. and the central notched portions of the dogs being displaced nutwardlv out of pivotal engagement with the res ective brid es 25. The rim portion of the foremost cu'o finally passes over the front tee h 22 of the dogs. permitting removal of the nun from the casin the following cup being retained in the casing by the rear teeth 2| of the dogs; Succeeding cups are withdrawn in the same manner, the nested cups being urged forwardly by the spirally coiled feeding spring 34. When the last cup is withdrawn the follower 33 is retained by the dogs. The yielding mounting of the rockable dogs permits the foremost cup to be withdrawn without injury, while still providing the desired gripping and restraining action on the following cup. An advantage for the feeding spring 34 is that the feeding pressure .walls and having inturned rear flanges -|08 is adapted to fit.

on the cups remains substantially uniform whether the casing is full or has only a single remaining cup. The portion of the spring extending from the anchorage 35 to the coiled portion is substantially fiat and bears on the web of the channel member l2 out of the path of the cups.

To load the casing, it is only necessary to push a stack of nested cups into the casing, the spring-pressed rockable dogs 20 being forced outwardly by the rim portions of the cups as the cups pass into the casing. The yieldable mounting of the dogs permits both the front and rear projections of the dogs to be depressed simultaneously, thus avoiding injury to, or jamming of, the cups during the loading operation. This mounting also permits the follower 33 to be inserted into the casing through the dispensing opening after the dogs are installed.

It will be obvious that the feeding spring can be used in other types of dispensers, such as napkin dispensers. The feeding means forms the claimed subject-matter of my copending application for Cup dispensing device, Serial No. 273,628, filed May 15, 1939. The use of feeding means permits the dispenser to be mounted in various positions including an up-feed vertical position.

In that form of. the invention shown in Figs. 9 to 19, H0 designates a holder-forming casing in 'which is detachably mounted the lower end portion of a cardboard cup package or carton I08 of a well-known type, the package enclosing therein a, stack or succession of nested paper cups 8., The package is here shown to be of the usual square cross-section and sometimes bears suitable advertising or other indicia (not shown) on one or more of its sides. The lower end wall of the package is opened to permit the dispensing of the cups bottom end foremost.

The casing ||0- comprises asheet metal band or plate I31 bent to form a front wall and side I38 which are rigidly secured, as by spot welding, to the rear face of 'a back plate I39, thus forming a hollow square structure'within the upper portion of which the lower end of the cup package The casing further includes an inner sleeve or shell I which is formed by bending a sheet metal band to cylindrical shape and which fits within the hollow square portion of the casing. The sleeve is secured to the back plate I39 by a rivet |4|I passing through registering notches I41, Fig. 17, in the longitudinally split rear portion of the sleeve, the fastening of the rivet serving to expand the split sleeve into snug engagement with the inner wall surfaces of the hollow square portion of the casing. The upper edge of the shell or sleeve III is spaced downwardly from the upper edge of the casing band I31 and forms a stop for the open bottom end of the cup package. The front and opposite side walls of the casing band I31 are embossed with vertical stiffening ribs I42 which also serve to provide ornamentation. The cup package forms, in effect, an upward extension of the casing.

The back plate I39 extends somewhat above the casing band I31 and at its upper end carries opposite forwardly projecting resilient ears I43 which are bent to present vertical ribs I44 at the inner sides thereof to engage and indent the resilient side walls of the cup package, as seen in Fig. 13', thus firmly holding the package in position on the casing. The retaining ears facilitate the mounting of the package and avoid obscuring any indicia that may be present on the front and side walls of the package. The ears I 43 are here shown to be formed on the ends I of a sheet metal strap I45 which is secured, as by spot welding, to the rear face of the back plate. The opposite side edges of the back plate are beaded or doubled on themselves at I46 to avoid sharp edges and to provide stiffness.

A flanged wedge plate I I is rigidly secured to the rear face of the back plate I I2 and is wedgingly engageable in a mounting bracket II6 secured to a vertical supporting wall I II, the holder being urged downwardly to a wedging position.

The cups IIB descend from the cup package or carton into the cylindrical sleeve or shell III below which the lowermost cup extends, and are releasably retained in the shell by a plurality of spring-pressed dogs I mounted in the shell, four peripherally spaced dogs being provided in the present instance. The dogs are similar to those of the device of Figs. 1 to 8, and each consists of an elongated block, preferably of metal, extending longitudinally of the shell and having a pair of longitudinally spaced, pointed teeth or projections I2I and I22 which extend respectively through a pair of vertically aligned slots I23 and I24 formed in the shell, there being a fulcrum-forming bridge I25 between these slots fitting in a fiat-bottomed notch I26 formed in the dog between the teeth. The dog pivotally bears on the bridge to permit a limited rocking movement of the dog. the opposite ends of the dog having stop projections I2! which are engageable with the outer surface of the shell beyond the ends of the slots I23 and I 24. The dogs extend outwardly of the shell into the open corner spaces of the casing and are held in their slots by respective leaf springs I28 extending longitudinally of the shell, the upper ends of the springs being secured. as by riveting, to respective tongues I30 struck up from the shell. Each spring has an inturned lower free end I41 which is urged inwardly and which bears in a notch I29 formed in the outer edge of the corresponding dog, the notch being somewhat wider than the thickness of the spring so as not to interfere with the rocking of the dog. The inturned end of the spring has a central notch I48 to admit the notched outer edge of the dog and thus maintain the spring in operative -engagement with the dog, the notch I48 being slightly wider than the thickness of the dog. The spring normally holds the dog in the position shown in Fig. 15. During manufacture. the dogs and their sprin s are readily applied to the sleeve or shell III, which then forms a conveniently handled subassembly. After the sleeve is incorporated into the casing, the outer walls of the casing conceal the dogs and springs.

When the device of Fig. 9 is in use. the stack of cups is urged downwardly by gravity. the bead or rim portion II9 of the lowermost cup being supported on the upper teeth I2I of-the retaining dogs I20, as seen in Figs. 12 and 15. When a cup is to be dispensed, it is grasped in the fingers and pulled downwardly, the rim portion of the cup depressing first the upper teeth IZI of the dogs and then the lower teeth I22 and causing the dogs to pivot on the bridges I25. The operation is substantially the same as that of the device of Figs. 1 to 8. Fig. 16 shows the lowermost cup passing the lower tooth of one of the dogs. At this stage the upper end I 21 of the dog pivots on the outer wall of the sleeve or shell, although in some instances the inwardly urged upper tooth I2I of the dog may pivot on the rim portion of the second last cup. Although the cups may adhere to each other to some extent, the cup which follows the one being withdrawn will be prevented by the inwardly urged upper teeth of the retainingdogs from leaving the casing. The rim portions II 9 of the cups may be relatively stiff, but the yielding dogs will readily permit the passage of the lowermost cup.

When the cup package is exhausted, it is lifted out of the casing and is replaced by a new package, the cups thereof descending into the casing until the rim portion of the lowermost cup rests on the upper teeth of the retaining dogs.

The construction of each form of dispensing device insures withdrawal of only one article at a time, thus avoiding waste.
