Patented Aug. 15,l 15939 V DISPENSING CABINET AND MEANS FOR MOUNTING A SUPPLY ROLL THEREIN Frank G. Steiner, Chicago, Ill., assigner to Stein- I er Sales Company, Salt Lake City, Utah, a-cor'- poration of Utah Application January 12, 1938, Serial No. 184,648

11 Claims.

'I'his invention relates generally to paper or sheet material dispensing devices, and relates particularly to means for mounting a supply roll of paper in a cabinet, and f or facilitating-the connection of the roll with the mounting means. The invention has for an obfiect to provide means for preventing wrong placement ofthe roll with reference to a dispensing mechanism.

The means for preventing wrong placement of the roll is related to the broad idea (disclosed in my co-pendlng application 40,794 series of 1935) of so feeding paper from a roll; that the tendency of the paper to curl in a direction toward the roll is utilized forcausing the paper (after delivery through a delivery opening) to assume and 'be maintained in outwardly spaced relation with respect to the front face of the cabinet so that its end can be easily grasped.

This invention is also related in some respects to the invention disclosed in the application of Merle J. West 140,213 series of 1935, now Patent No. 2,146,038 of Feb. 7, 1939, which broadly pro'- vides means for preventing such wrong placement .of a roll, as would defeat the purpose of utilization of the curl'of the paper, for making the same more accessible for grasping.

'I'he main objects of the present invention are, to provide means for preventing wrong placement of the roll, and to provide means for facilitating connection of this last mentioned means. Another object is to providea new means for facilitating the connectionvof the roll with its mount,'independently of any scheme for preventing wrong placement. I believe myself. the first In the West'application 140,213 supra., now

Patent No. 2,146,038 although means are provided for preventing wrong placement of the roll, the connection of this means might sometimes be didlcult because of the'requirement of the registration between elementsv carried respec tively by the roll and by the mount therefor. The present invention not only provides new forms of connecting means between the roll and the mount. but provides means by which such connections are facilitated.

Features ofthe invention include all details of construction shown, along with the broader idea 60 ofproviding guiding means for facilitating connection of the4 connecting means; f

Objects, features and advantages of the inven- -A tion will be set forth in the description of the 55 in said drawings,

, In the drawings, the device has been shown ous kinds of cabinets.

The cabinet is generally indicated at I. 'It hasa front wall 2 having a delivery opening 3. In this instance the front wall 2 is pivoted as at 4 tothe bottom of the cabinet to swing downwardly to a point below the cabinet. The upper edge 5 of the down-swingable front 2 cooperates with the lower edge 5 of the top of the cabinet to define the down-leading delivery opening 3.

Rolls I5 and I6 cooperate to feed the paper. Roll I5f is operated by va crank 28. A suitable guide 2| directs the paper outwardly and downwardly through the opening 3. The paper is guided upwardly and over a tearo knife or blade 25 by which the paper is separated as a result of pull thereon.

It willbe noted that face 21 of the paper which was opposed to the roll faces, after ejection through the opening 3, is directed toward the user and away from the front 2 of the cabinet. It is noted that paper curls outwardly, and thus the natural curl of the paper, due to its original roll formation, is utilized for facilitating grasping.

Referring now to Figures 2 and 3, a supply roll of paper is indicated at 30, and a hollow paper core or tube for the roll is indicated at 3|. The roll itself may ,be said to provide vaiirially alined openings or depressions at opposite ends,

but preferably these openings are formed in or by a tubular core or by a core having openings in its ends. Upon this core the paper is wound tightly. This core thus constitutes an element which is permanently nonrotatably secured in the roll, in a manner to strongly resist detachment. i

The support or mount for the roll includes an element of sheet metal having a horizontal portion 32 and bent up arms 33-34. pivoted as at 35 toa plate 35, which plates extend vertically o'f the cabinet and are spaced inwardly from the outer walls 31 of the cabinet. While the particular mount is claimed in combination it is understood that the invention is broader than vthe particular structure of the mount.

Referrlng'rst to the form of invention illustrated in Figures 1 to 5 inclusive, broadly, means is provided for detachably mounting the roll, including parts which facilitate connection of parts on the roll with parts on the mount.

Referring rst to Figures 3 and 5, a cap-like lelement48isiittedwitl`iinthecoreu soasto close one end thereof.l 'Ihe cap may nt' ina depression in a core. Terminal prongs are provided on the circular inner margin of'this member 4l, the prongs being indicated at 4|. There are four of these prongs only threeof which are shown. Element 40 is shown asa cup orcap but may be a disc or plate. The use oi this ele-i ment and its immovable attachment in the manner shown is a` feature. As attached it' cannot be removed without considerable diillculty until the supply roll is depleted. `The element is introduced and moved to the position shown in Ill'ig-` ure 3, at which .time the prongs are alined with a cylindrical wall of the cap 4II. After the capv Eacharmis.

has been positioned as shown, a tool is introdud into the co're from the opposite end'and the prongs are. forced outwardly to bite into the paper of the core. This is a very eifective and simple means for substantially non-removably and non rotatively securing the cap within the core.

The cap 40 has punched-outtherefrom a pair of parallel flat ears or projections indicated by the numeral 45, and also has punched out therefrom a pair of arcuate ears or projections 46. 'I'he guide ears 45 are alined on a diameter which passes through the rotative axis of the roll. 'Ihe elements and 46 are symmetrically arranged as are the corresponding elements o-f the mount (see Figure 4), later to be described, to the end that the elements will register forconnecting the parts together and to the end that the guide means can cooperate for facilitating this connection. While the specific one-piece construction of its cap and connection and guiding-means is claimed per se, there is no intention to limit the broader aspects of the invention to. thisspecific construction.

Referring now to Figures 2, 3 and 4, there is rotatably mounted upon the arm 33 of thev swinging'mount an element generally indicated by the numeral 48 which is formed by bending a pieceA v I of metal to provide portions 49 having their4 ends spaced to provide a guide slot 50, adapted to receive the projection or fln formed by the members 450i the cap 40. The element 48 is rotatably mounted in an opening 5I of the arm by means of a tubular extension 52, as` show n. Arranged symmetrically on opposite sides of the slot 50 are arcuate slots corresponding in shape-'and adapted to receive elements 45 of the cap 40. Just as soon as members 45 enterslot 50 it is only necessary to slide the parts in one direction or another to cause lelements 46-55 to register so that elements 45 enter the slots or openings 55. Arm33 is slightly sprung outwardly beforethe .parts 45 enter the slots 55, and just as soon as these parts register the arm springs inwardly automatically. Thus a very simple means is provided for facilitating the connection between the parts 45 and 55. The thickness ofthe fins 45 and the width of the slot 5|) are so proportioned as to slide easily one inthe other. `It will of course be understoodv that the s1ots'5o and ss may be in the cap 40, and the projections 45 and 45 may be on the part 48, thus. obtaining a lreversal of the parts. The means for facilitating'the Iconnection are broadly claimed although the preferred form shown, is also claimed. There might be some advantage in making the cap- 40 l pro- The arm u has rotatably mounted thereon a projection 58', a pin 6|' riveted to the part 34 serving as means about' which 'this element rotates. This element 68 isrounded as shown to ilt into the1 end of the tube. It is evident from an inspection of Figure 2 that if the roll were turned end for end, that is, if the part 40 were positioned at the right instead of at the left, no .proper connection with the support orzswing frame could be made. This is the ,feature which prevents wrong placement of the roll with referenceto the'feedins mechanism and front of the cabinet. It 'may here be said' that any suitable mount equivalent of the arms 30--34 may be used, it being understood thatA it is not necessary in all cases thatY there be any movement of the mount. I'he part 43 could be rotatably iconnected wth the plate 35 or with the wall 31. l'Jlhefra'me is'the'pre-.u

aieaasa ferred construction because it can be swung to a point outside of the cabinet. i

Referring now to the modification illustrated in Figures 6 to 10 inclusive, the cap element is generally indicated at 56 and is connected kby vmeans of the prongs 4|' as in case of the rst form. Referring to Figures 8 and 10, the cap or` form and which are symmetrically placed with reference to the axis of rotation.

It is noted that the cap and its elements 59 and 60 are all of one piece of metal made -.by

punching, and this' isla feature of all of the de-v vices herein, including the mount elements.

Referring again to Figure 8 the arm 33 has rotatablyattached thereto by means of a tubular extension 62 a mount element indicated at 6|. This element 6I is formed by 4bending a strip of metal upon itself as shown to form a spaced out guide portion 63, which is narrower than the base portion. The ends of the element are secured asr by spot Awelding at 64. This guide part 63 slidably fits between the parallel elements 59. Introduction by sliding motionmay be made at either end of the element 6|. In this guide portion 63 are two arcuate slots 68 which positionally corre spond to and which receive the arcuate outstanding ears or lugs 60 of the cap. It will be seen that as soon as the part 63 is placed in the groove l formed by parts 59, slight sliding motion one way or the other will bring parts 60 into registration with the parts 68, to enter thereinto, 'and thus connect the roll to the mount.

Referring Vnow to Figures 11 to 13 inclusive, in this form no guiding means to facilitate connection is used. The cap 10 is provided with prongs 4i", and with punchedout outstanding arcuate portions 1I symmetrically arranged as shown about the axis of rotation of the wall. The arm 33 has rotatably secured thereto a mount element 15 rotatably'held by means of a tubular portion 16. The element 'l5 has end portions 11 formed by bending inwardly as shown, and the ends of these portions are so formed that they cooperate to deilne an open-end S shaped slot 18. The shape of this slot is such as to receive and connect with the arcuate parts 1i. The specific construction of this device is a feature of this invention.

.Referring now to Figures 14 and 15 another modification is shown in which the cap is provided with punched-out guide elements 60, and with outstanding arcuate elements 8l. All elements are arranged symmetrically asin the other cases. The connecting mount element which is attached to the arm 33 has a structure substantially like Figure 9 with the exception` that the S shaped slot 6?. is closed. The slot is adapted to receive the parts 6l which as viewed in Figure 15 are reversed S shaped. Again it is noted that the cap may have the slot and the mount have the projection.-

It is further noted that in all formsof the in'- V vention with the exception of that form illustrated in Figures 12 and 14, guidemeans is-provided for facilitating the connection between the elements respectively of the. cap and of the mount. 4This means is therefore broildllli claimed because I believe myself the rst to kprovide any means for facilitating such a connection and moreover the rst to provide any of the specific means shown herein and the first to connect a cap in a core immovably and simply and in the manner shown.

It isA again noted that the cooperative locking parts are arranged symmetrically about the axis ofrotation lof the roll. Just as soon as registration is obtained between the guides, it is only necessary to slightly slide'the parts in one direction or another to cause the connecting means to connect. In both forms the guide means'provide a. projection on one of'the elements fitting a groove in the other.

It is further noted that the projecting parts of the guide means are longer in an axial direction than the projecting parts of the'connecting means, so that the slide or guide groove 'is deep enough to perform the guiding function while the outer ends of the projecting parts of said connecting means ride along the inner surface of the guide part of the mount. l

In Figure' 16 a modification has been shown 4wherein a ring or annulus is attached to the core.

In this, as in the other forms, the attachment' is made by expanding'the prongs, to cause them 4to bite into the material of the core and thus immovably secure the cap or ring.

Numeral generally indicates a cap having punched out diametrically related arcuate attaching projections 9|. The ring 90 has inward extensions which, normally or before attachment of the cap, occupy the position shown in the drawings, but which arevto 'be expanded outwardly as indicated by the arrows by a suitable. tool introduced through the opening 93 of the ring. It, of course, will be understood that when this occurs the prongs 96 bite into the material of the core 3i as has been indicated in Figure 17.,

vThe advantage here is that instead of introducinga tool, or mandrel, from the opposite'end of,

the core, the expanding tool may be introduced through an opening in the ring, that is, introduction is at the same end as that to which the cap is attached. The cap in this instance has a spool-like relation to the material on the core.` 'Ifhat is. it overlaps thismaterial. Numeral 33 indicates one of the arms of the swinging mount and this arm has attached thereto an element .indicated at 98 which is the substantial equivalent of element 15, of Figure 11, and which has therein arcuate slots 91 receiving the arcuate projections 9|. The feature of this form hasin common with the feature of the other forms, the connection of the cap by expanding prongs into the material of the cover.
