Specification of Letters Patent.
Patented Apr. 9, 1918.
Application filed December 19, 1914. Serial No. 878,086;
To all 10 ho-m it may can (761%! Be it known that I, LAWRENCE W. LUEL- LEN, a citizen of the United States, residing at Mountain Lakes, county of Morris, and State of New Jersey, have invented certain new and useful Improvements in Dispensing Devices, of which the following, taken in connection. with the accompanying sheets of drawing, is a full, clear, and concise descrip-.
My present invention relates to certain improvements in dispensing devices, that are particularly adapted to dispense paper drinking cups. In United States Letters Patent No. 1,043,85 l heretofore issued tome, a dispensing device for paper drinking cups is shown in which a cup reservoir and a supporting bracket nested stack of paper cups ina sanitary condition and inv such a position as to enable the cups to be conveniently and individually withdrawn, the terminal cup of the stack projecting beneath the device to be grasped by the hand of the user.
The present invention is an improvement on my said previous patented invention, and comprehends primarily mechanically operated means for separating the terminal cup from the superposed stack and moving the same to delivery position, while retaining the balance of-the cups within the device.
A further object of my invention is to provide a new and improved form of bracket support which normally houses the terminal cup of the stack prior to its deliverance, said bracket support being provided with means for arresting tl-e descent of the terminal cup and retainingit in position whereby it can be conveniently grasped for removal. Other and further objects will manifest themselves upon a reading and understanding of the following description.
' Referring to the accompanying drawings, in which I have illustrated one preferable embodiment of my invention, I will proceed to describe the same,- having it understood that the form shown is illustrative, rather than definitive, as structural changes may be resorted to without departing from the invention as defined by the appended claims.
Figure 1 is a top plan view of the bracket support showing, generally, the cup separating and delivery instrumentalities in dotted outline, illustrating their relative positions.
Fig. 2 a view in side elevation taken on is used for storing a v 7 7 9,231, I have illustrated a paper line aa of Fig. 1, being broken away to illustrate more clearly the cup supporting ledges of the supporting devices, and their operative relationship tothe cup flanges.
Fig. 3 is a bottom plan view taken on line 6-6 of Fig. 2 to illustrate the structural characteristics of the top plate of the bracket showing the manner in which the cup separating and supporting instrumentalities cooperate therewith.
Fig. i is a cross-sectional view taken on line 0-0 of Fig. 2, illustrative of the manner in which the terminal cup of the stack is retained in delivery position.
Fig. 5 is a view taken on line d-cl of Fig. 1 showing the position of the cup separating mechanism after functioning. I
Fig. 6 is a view taken on line 6-6 of Fig. 4, showing in top plan the spring actuated re-setting mechanism for returning the delivery actuator and supporting instrumentalities to'their initial position.
Fig. 7 is a view in perspective of one of y per, which may be water-proofed by a coating of paraffin or similar substance. compactness and convenience of shipping and handling the cups are nested. Owing to the cohesive properties of the waterproofing material, it frequently cups become stucktogether. It is therefore, desirable to provide a mechanism which will overcome this tendency and positively separate them, one from the other. Thls accomplish by the vmechanism herein lllustrated, without'in any way marrlngor distorting the flanges of the cups. MllllOIlS of paraffincd paper drinking cupsare at present used annually, and, therefore, 111 this connection my invention possesses great utility.
In my co-pending application, Serial No. drinking provided with what I term a This cup is not waterproofed destructible than a cup which is rolled edge. and is more readily parafiined paper cup, desirable as CODdllClVG toward smgle use. The frailty and unsubstantial character of happens that two For a feature which is the part 2 for the purpose of replenishing the device with cups. The bracket part 3 is provided With a cylindrical extension or petticoat serving to house the lower portion of the terminal cup as Well as several of those superposed above it. The lower end of the housing is constricted as 5, forming a throat of slightly less internal diameter than the diameter of the flange the cup, so that the terminal cup, when it drops into delivery position (see Fig. Will be retained by the engagement of the cup flange with the throat, from which position the cup may be readily removed by a slight pull. The two-part bracket support is rec tilinear in outward form, as shown clearly in Fig. 1, excepting that portion which forms the petticoat or housing for the terminal cup, this being cylindrical. The part 2 of the support is provided With a bracket 6 cast integral therewithand serving to atvford means by which the device may be tastened to a support. t is also Provided with an upwardly extending circumferentially arranged flange 7 and an inwardly directec ledge or seat 8 both of which serve to support and retain the removable glass reservoir 1 in its proper position. The parts 2 and 3 are held. together by suitable screws, four in number, passing through alined aper tures 9. Both of these parts are cast in the special forms shown so as to provide the re quired seats for the accommodation of the actuating instrumentalities to be presently described. T he part 2 is cast with two pairs of projections 10, diametrically opposite to each other. lugs 11, through which the screws, fastening the parts together, pass, serve to form rectangularly disposed passages or channels along and through which the cup sustaining and delivery devices reciprocate during manipulation. The channels 12 accommodate the pair of cup supporting members 13, while the channels 14- accommodate the combination on sun ortin and delivery momaround three of its sides and partly around its i ourth leaving a gap 1? to acccrareservoir bei' removable rrom.
These. in combination Withthe modateand permit the movement of the handle 18 of the actuator ring 19. Within the space formed by theupwardly-extending wall 16 is a spring 20, one end of which is anchored to a lug 21 cast integral With the part 3. The other and opposite end of this spring is anchored to a corresponding lug 22, which projects beneath and is cast integral With the actuator ring 19. The spring 20 is located beneath the actuator ring 19, said actuator ring resting upon the annular projection 23. The spring 20 is put under tension when the handle 18 of the actuator ring has been operated, and serves to return the same to its initial position.
The actuator ring 19 is provided with two sets of diametrically opposed projections which engage and actuate the escapement mechanism consisting oi": the cupsupporting and separating members 18 and 15. These cup supporting and separating members are given a rectilinear movement along the channels in which they are located by the partial rotary movement oi the actuate ring 19, sufficient lost motion being allowed between the projections 2% and the depressions or apertures 25 of the cup-sup porting members to accomplish this. The cup supporting members 13 are positioned and move in opposite direction, but in arallel relation. The cup supporting and separating members 15 are similarly located and similarly move in the passages or channels provided therefor. The four members comprising the escapement mechanism are thus simultaneously actuated and move in definite relationship to dispense the cups one a time.
The cups are sustained Within the device by the rim oi the terminal cup, which normally rests upon projecting shelves or ledges 26 and 2? of the members 1? and 15. The members 13 normally are disposed diagonally opposite each other at the extreme end of their rectilinear travel when the dispensmg mechanism is inactive, prior to operation. The same may be said with respect to the members 15. In this position, as shown clearly in ig. 1, these shelves or ledges, which are all in a common plane project Within the annular dispenser opening of the device, and directly under the flange oi the lowermost cup. 'lhese sup porting ledges do not extend the length of the member, but terminate at a point near the center thereof, so that When the members travel the extreme length of their movement upon the rotation of the actuator ring, they pass beyond the cup dispenser opening so as to permit the flange of the terminal cup to pass and drop upon its egress from the device.
Understanding. that the bottoms of the paper cups are sli 'htly removed from their L flanges wi l ends,
consequently be spaced one from another when the cups are in nested position This spacing of the flanges of the cups affords an opportunity of providing a mechanism for dispensing the cups from the device individually or one at a time. As the shelves 26 and 27 of the members 13 and 15 move away from the delivery aperture, other shelves 28 and 29 of the members gral therewith and are located on a higher plane than the shelves 26 and 27, are projected into the delivery aperture underneaththe flange of the cup next succeeding the terminal cup, engaging the rim of the second cup and coming into substantial supporting position thereunder before the lowermost shelves 26 and 27 pass from beneath the flange of the terminal cup. IVhen the shelves 28 and 29 are in their full cup sustaining position, the lowermost shelves 26 and 27 have passed from beneath the flange of the terminal cup and have permitted the terminal cup to descend.
In the eventthat there should be slight adhesion between the cups, which would prevent the terminal cup from dropping by gravity after the lowermost shelves 26 and 27 have passed from beneath its flange, the ejecting mechanism which I have provided comes into action and operates to loosen or pry them apart by exerting a downward pressure upon the rim of the terminal cup, and this automatically as the device is operated. This ejecting mechanism is combined with a pair of the cup supporting members 15. Ther e being two of these mechanisms, both being of the same general construction, a description of one will suffice. Pivotally mounted on the carrier at 30 is an ejector 31 having a flange engaging part 32 which forms in inactive pos1tion,'
a prolongation of the shelf 29. This ejector ismounted so as to move downwardly within the member .15,which is made in channel form for the purpose. The pivoted end of the ejector 'is provided with a wedge surface 33, which engages an inclined lug 34 (see Fig. 5), when the member 15 has been moved to its extreme position under the rotation of the actuator ring 19. During this movement, the lug 34 forces the ejector 31 downwardly, bringing the part 32 into engagement withthe top of the rim of the terminal cup and pressing it downwardly, causing the terminal cup-to separate and drop by gravity. It will be noticed that this ejector does not start to move until the member 15 has almost reached the limit of'its movement and the supporting ledges or shelves 26 and 27 have passed from beneath the flange of the terminal cup. In order to retract the ejector 31 to normal inactive position, I mount a torsion spring 35 beneath having one end engaging the base of the member 15 and the other free end engaging 13 and 15, which are formed inteof distortion or the underside of the actuator, so that the actuator when moved to eject a cup, is operating against the tension of the spring. As the terminal cup passes from the supporting shelves of the members 13 and 15', and has been separated from the adjacent cup by the ejeetors 31, the cup descends or drops by gravity. The cup is halted in its descent by the engagement of its flange with the contracted. throat 5 of the bracket (see Fig. 4:). The cup is thus supported and retained in position with its major portion projecting beneath the device in position to be grasped by the hand. The proportions or diameters of the cup flange and the contracted delivery aperture or throat, need only be such as to aiford slight engagement between the two, because an individual cup has very little weight and no substantial point of contact need be necessary between the cup flange and the engaging throat of the device. The cup will be sustained in delivery position and will require but slight pressure to remove it, sothat. no possibility disfiguration of the cup or its flange will result due to flexure or otherwise.
Having thus described my invention what I claim as new herein and desire to secure by Letters Patent is:
