18 Claims.

This invention relates to improvements `in devices for dispensing material in roll form, and has among its objects to provide means for preventing the dispensing of unauthorized material, that is for preventing dispensing unless the supply roll is equipped with some means which can cooperate with some means in the cabinet for allowing the roll to be moved to a proper'dispensing position. An object is also to prevent the dispensing of inferior material.

Where paper in roll form is used, and particularly where it is supplied free of charge. It is desirable to prevent waste of paper. An important object herein is to provide a cabinet adapted to dispense paper only of a certain high quality, and to prevent the use of paper of inferior quality, and to prevent waste of the paper. In order to force the use of a certain quality of paper, means is provided to prevent the dispensingof any roll of the supply material or to prevent its movement to a position at which it can be dispensed, unless said roll is equipped Witha device which co-acts with a device in the cabinet to permit such introduction and positioning.

Another object of the invention is to provide a rotatable mounting means for a roll or rolls of supply material, and another object is to provide means adjustable for frictionally retarding the rotation of said mounting means in varying degrees conformably to the tensile strength of the paper. certain tensile strength, and in some supply paper the lengths ofthe paper are dened by periorations. Therefore, to control the rate of withdrawal and thus prevent waste, means is provided which yieldably resists roll rotation due to pull on the paper. The amount of yieldably resistance required depends upon the quality of the paperand depends on the rate of pulling which is to be permitted. If after the retarding means is set, an attempt is made to dispense the paper by pulling it out too quickly it will break or it will tear ofi along perforations which define a single length. l

The invention herein is applicable to the same general type of cabinet shown in our co-pending application for Method And Means For Dispensing Material In Roll Form, Serial No. 642,498,

filed January 2l, 1946, now Patent No. 2,553.389, dated May 15, 1951. Although the invention herein is applicable to the type of cabinet shown in the aforesaid pending application, yet vsome phases of the invention herein are applicable to. other types of cabinets,

Further objects of the invention are to provide improved cabinet structure; to provide means for preventing the dispensing of an unauthorized supply roll; to provide a new and The proper quality of paper has'a 2 simplified form of cabinet; to provide cabinets of varying heights which will house two or more supply rolls placed end'to end with their axes in vertical alignment; to provide means adjustable in varying degrees, for iricticnally and yieldably resisting withdrawal of the material of the supply roll conformably to the tensile strength of the supply material; to provide a simplified form of upright spindle as means for holding a supply roll in dispensing position; to provide a spindle structure which can be made by simple assembly of parts which are formable by stamping and punching operations; to provide a threepiece cabinet of which the pieces are stamped and formed of sheet material; to provide a cabinet in which dispensing can only occur when a tubular supply roll is held with its axis in upright position; to provide a roll as an article of manufacture having a crossbar secured within its core; and to provide a method for applying the cross bar.

Objects, features and advantages of the invention will appear in the description of the drawings, and in said drawings:

Figs. 13 and 14 show the bar bent upon itself to reinforce and stiffen it; and

Fig. 15 is similar to Fig. 7 and shows means for automatically intermittently. varying the degree of yieldable resistance to'rotation of the supply roll, during dispensing.

Now referring to the drawings: The cabinet casing is constructed of sheet metal and, with the exception of a top cover, is composed of only three pieces. The rst piece forms the back section I. This section I has near its top a keyhole slot (see Fig. adapted to fit over a projection on a wall as a hanger for supporting the cabinet. The back also has a pair of openings (only one shown) through which fastening devices may be inserted to secure the back against swinging.

The second piece provides a front-2 and sidewalls 3 for the cabinet. The front V2 of this secondl piece is of semi-cylindrical configuration and it extends downwardly from the top only a distance which is equal to about half of the total height of the cabinet. The sides 3 are rearward/parallel extensions from this semi-cylindrical iront wall.

Each side 3 has a verticalflange 4 engaging with the rear surface of the back element I throughout its entire vertical height. These anges are secured by spot welding. The front edges E of the 'lower portions of the sides slant downwardly and rearwardly as best shown in Fig. 2. At the lower edge of the cylindrical wall andalong the edge 5the metal is turned as at 6 to give a smooth finish.

Thethird piece or bottom I of the cabinet has a rear flange 8, which is-secured to the front surface of the back element I, and the bottom has side 'flanges 9 which are disposed toV be forwardly convergent as shown in Figs. 3 and 7, and which are continuous with a curved portion which lli'es at the extreme `front. The vertical heights of these side flanges decrease as they converge forwardly so that there are Vprovided downwardly forwardly slanting upwardly faced edges lII) sometimesv referred-to herein as dragedges. These edges are-adapted to act asffriction drag means engageable by the bottom end of an unauthorized supply roll, under certain` conditions to be mentioned hereinafter.

'The cabinet is provided with `a top colver `I `2 which can be openedfor top. loading. rI'he cover is hinged at the rear of the back I. For'thispurpose the back is provided with two short upper terminal rolled portions I'Il and the lid is provided with an elongated rolled portion I5. A suitable pintle I6 traverses the rolledA portions vas best shown in Figs.'2 and 6. The lid has a marginal downturned flange which fits'the front and side walls as shown. The lid is also provided with a lock I'I the bolt of which engages a 4flange formed by overturning the top "periphery of the semi-cylindrical portion at the front '2 asbest shown in Fig. 5. Centrally of the lid'there is provided a cylindrical cup I9 opening downwardly and suitably securedby means. of, a Screw as shown. This cup as shown inFigsfe, 5, and 6'is adapted to engage over the upper end of an upright spindle on 'which 'the supply 'rolls are supported for storage and dispensing.

A very important part of this invention'is the spindle and the means thereon vandjtherebelow for preventing anyunauthorized supply rollY from assuming a position which will permit unimpejded dispensing. The principle underlying this phase of the invention, i's to prevent any unauthorized roll from arriving Aata position at'which it can be dispensed, if the roll is not equipped witha suitable stopping and/ ortripping device, adapted to trip a stop on an element 'whichfsupports the roll. The idea is toH allowa standard supply roll to arrive at dispensing position. butto prevent the arrival of a substitute non-standard roll at that position.

Asbest shown in Fig.v S'thiSspindlef is generally designated 25 and is supported for rotation on a post 26 which is rigidly non-rotatably secured to the bottom 'I of the cabinet in the upright position shown. Its axis is coaxial with the axis of generation of the semi-cylindrical wall 2. Rotatable about this shaft is a washer 2l which may be of bronze, and the lower end of the -spindle l2li rests on this washer which in turn rests on the bottom S, and the spindle and the washer can rotate.

The-structure -of the spindle is a feature of the invention. Thespindle 25 is formed to provide diametrically related slots 30; to provide for its rotative action upon the post; to provide a trippable latch and detent arrangement; and to provide means for obtaining yieldable resistance to its rotation on the post.

The spindleV is composed of two halves 28, each given a form somewhat like that of a channel iron and these channels are then attached to the outer sides of two rectangular thimbles 3l arranged in the lower part of the spindle. These thimbles are formed in the iiat by stamping, and are then bent to provide flanges to which the channels are connected as by spot welding, and in such spaced relation as to provide the diametrically related slots, 30. These thimbles are arranged in vertically spaced relation near the bottom of the spindle and each has a cylindrical bearing fl'ange'3'2 which is rotatably engaged with the post'. This spindle is thus constructed by elements, all of which can be made by punching and stamping and it will be further noted that a rigid structure is provided by the means herein shown, and that a very effective bearing is provided which maintains the spindle in upright positionwithout any lateral play.

v The walls of the channels are cut out as at 33 to permit the introduction or removal of a resilient bowed member 34 which is part of the means for adjusting and varying the frictional relations between the spindle and the post. A screw 35 is threaded into this bowed member and has a slotted head 36 which is received by a socket v3"! of either channel. The head abuts the channehand when the screw is turned the degree of pressure on member 34'can b'e varied, to correspondingly vary the frictional resistance against which the spindle must be turned.

This'means by which the frictional resistance to the rotation of the spindle can be adjusted in relation to the quality of the paper used or to b'e used, is an important feature. The good quality paper to be used herein must have a certain tensile strength. The tension adjusting meansA is therefore manipulated to apply a proper amount of "fricticnal resistance to the rotation of the spindle by the roll. The adjustment can be so made asto save papenand is so related to the degree of tensile strength of the paper, that if an attempt is made towithdraw paper too quickly the paper will prematurely break. The slowing downjof the withdrawal rate-saves considerable paper.

VSimple removal'ofthe spindle 25 from the post 26: is prevented by'means of a split 'spring ring 40 fitting in aV circumferential groove 4I of the post* 2 6. The spring is applied through opening 42 in'one of the channels.

Arranged' in the upper part of the tubular spindle 25 is a device which in its functional aspect constitutes means for preventing movement of an unauthorizedv supply roll downwardly on the spindle to a point at which it can be dispensed through the dispensing opening. This opening is., defined bythe semi-cylindrical bottom edge of the front Wall 2, and by the bottom 1, see Fig. 2.

- This preventing means comprises a lever 45 having a hook like projection 46 passing through a slot 41 and pivotally held by a pin 48 which passes through punched out bearing depressions in one of the channel members, 28.

The projection 46 normally or initially occupies the position shown in Fig. 6, and the upper end of the lever 45 lies across a plane connecting the slots 36, so that a bar riding in the slots will engage that upper end and cam it to the position of'Fig. 4 to withdraw the hook 46.

The upper end of the lever has pivoted thereto a detent adapted to prevent accidental movement of the lever 45 from its position of Fig. 6 and to prevent movement of an unauthorized supply roll downwardlyon the spindle to dispensing position. This detent comprises a piece of sheet metal bent upon itself to a. somewhat U-shaped form, the U-end 50 being the heavier so that gravity action causes the detent to automatically assume the position shown in Fig. 6. In this position the arm of the detent lies across a plane connecting the slots and unless a supply roll is equipped with means for tripping this detent and bringing the lever to the position of Fig. 4, the hook 46 remains in preventing position. The upper end of the upper arm of the lever has a camming surface 52 engageable by the downwardly travelling bar of an authorized supply roll. In Order that, the lever may be applied or removed, after the channelshave been spot welded to the thimbles, an elongated opening 53 is provided in one of the channels. This opening is of -such a size that after the pivot pin 48 is removed, the lever with its detent can be withdrawn therethrough.

Moreover, another advantage of the angular arrangement of the said drag producing means is that if an attempt is made to cover the edges with a smooth plate, the cover element will be disposed at an angle to the bottom end of the supply roll or the roll will assume such an angle that friction will be generated to resist rotation of the roll for dispensing.

At the top of that channel on which the lever 45 is mounted there is a downturned element 55 at the top of the spindle which performs two functions. First it prevents the weighted or heavier end of the detent from overswinging in such a manner as to bring its weighted end to the wrong side of its pivot. Its second function is, to be engaged by the weighted end of the detent, as the upper arm of the lever moves by gravity in clockwise direction to assume its initial position, to positively cause the detent to be swung in counter-clockwisedirection to the detent position of Fig. 6. These movements to initial position, occur as soon as the lever 45 is released, as when a crossbar 56 of` either authorized supply roll 51 moves downwardly from a position whereat it engages the lever as ink Fig. 4. When the lever 45 is released its top arm swings in clockwise direction to assume the initial position of Fig. 6. It is to benoted that the mannerof placing the pivot of the lever at one side thereof and the shaping of the lever obtains this automatic gravity action to the said initial position. The inner edge of the lever 45, assumes a position substantially parallel with one side of slot 31, when brought to the tripped or permitting position of Fig. 4.

AThe authorized supply roll 51 having a core 6i) has the diametrically placed barv 56, and said roll thus equipped is claimed as an article of 6 manufacture adapted for use for tripping a device equivalent to the trippable device heretofore described, and as a stop for limiting downward movement of the supply roll at the proper position in relation to the dispensing opening. This bar engages the top of the post 26 as shown in Figs. 4 and 5, to limit an authorized supply roll at a position and in a condition for unimpeded dispensing action in relation to the dispensing opening. An unauthorized supply roll is indicated at 62 in Fig. 6. Since this roll has no means to engage the top of the post 26 to limit its downward movement, its lower periphery has engaged the drag edges l0 at two points 63, and when an attempt is made to pull the paper out, the paper will break because of the resisting action of the 'edges I0 onthe roll.

The crossbar 56 limits the supply roll at a posithe lever 45 in the position shown. The bar 56v when engaged with the slots 30, causes the spindle to rotate as the material is pulled off of the supply roll. Varying resistance to such rotation is obtained by adjustment of the bowed member 3134 in a manner heretofore described.

The arrangement of the drag edges is such that a two-point peripheral drag engagement is had for the unauthorized supply roll, whatever its 1 diameter may be. If it has a smaller diameter than that shown, then the two point peripheral drag engagement occurs forwardly and at a lower level.

If a person should remove the spindle 25 and attempt to support an unauthorized supply roll by means of the post 26 only, the attempt would be unsuccessful because the supply roll would assume a tilted position like that shown by dot and dash lines at 65 in Fig. 5. This would occur because of theY difference in the diameter of the post and of the core. In this case also the periphery of the unauthorized supply roll will engage at two points with the drag edges.

The paper core around which the paper is wrapped is provided with a diametrically disposed bar adapted to trip a device, which when untripped would prevent proper placement of the supply roll in a position to be dispensed. A feature of this invention, in addition to an article of manufacture as supply roll having a crossbar in its core, is the method for introducing said crossbar and rigidly attaching it within the core in diametric relation.

Referring to Figures 8 to 14. The crossbar 56, after being stamped, is bent at its ends into a somewhat U-shaped form to stiffen the ends. The extreme outer portions of the ends are sharpened so that their entry into and through the wall of the core will be facilitated. These ends are also provided with stop shoulders 'l5 which are adapted to abut the inner surface of the core to provide means by which the degree of traversal of the core by the ends will always be the same, because neither end can penetrate any farther than the distance defined by its stop shoulder.

In practice the method comprises, bending the bar as shown in Fig. 8, then introducing the bent bar to the position shown in Figs. 9 and 10, then straightening the bar to the position of Figs. 1l.

and 12'to1 cause its ends. to kbe xed in the. core, and, then bending the middle portion of the bar:

to a` U-shaped. conguration as shown in Figs. 1-3 and 14 to stifen it. In practice the bar is so disposed that its surfaces A and B (Fig- 14) both lie at thesame. distance from the corresponding end.' of the. supply roll, so, that no matter which endzofthe roll. isrst introducedover the spindle, the bar E6 whenit has engaged the upper. end of. the post. 26, will always be, so. positioned; as to hold the supply roll in proper relationto thev dis:- pensing. opening, and atv a level abovel the drag edges` |05 so that-the rollis free for rotation.,

Another and important object ov this, invention.. see Fig. 15.is to; provide means, which. will positively prevent theuser from pulling, out long lengths of the material, by a. slow. steady pull. Thisprocedure is easier of; accomplishment when the diameter of the roll is largest. Thev present device causes the paper to tear off alongfthe-perforations Whichv define a length of it. Heretofore there hasbeen described. means f'or frictionally. resisting the rotationY of the spindle, as rotated by pulling on the paper, and; the tension adjustment of this means in part accomplishes the .object above mentioned; However, when a new supply rollV is at nrst put in the cabinet less pulling tensionisrequired to rotate thev roll because ofA leverage advantagev due to its larger diameter. It is as though pulling actionv were applied. at' the outer end: of. a long` lever arm. However, as the diameter of the supply roll decreases, as dispensing precedes, a greater-pull or tension on the paper isrequired, and under these conditions with aV given setting of the; friction varying means the paper will generally unfailingly tear off along the perforations, becausegreater pull is required When it is` applied to a shorter lever arm. These perforations have not been shown, but their employment is'common.

Therefore, in order to assure this tear. off'vvh-en the roll is large, We provided means whichk Will automatically intermittently vary the; degree of resistance to pulling., during pulling. This automatic variation results in ai jerky action, to be explained, and occurs for-all: diameters of therolly pose is shownk only in Fig. 15, but said meansis adapted for and intendedto loe-used 'inconjunction with the structures previously described.

To this end-a post 8 I takes the placezof .post 25 and hasv the cross sectional conguration. of'. a regular polygon, having inthis instance siX facets 81. The ends8-2 of the spring lbow Sill-'Iare adapted' in this instance toflatly engage the-fac.etsas shown. When during pulling on-the paper these ends 82 ride over the longitudinal ridges 8-.3 formed by the intersection ofthe facets, .greater resistance to Withdrawal occurs, and the paper will' unfailingly separate alongya. perforated line. The `action is jerky, because the degree of' resistance to Withdrawal intermittently varies, as `rotar tion of the roll continues during. dispensing.
