Figure "llis a plan section showing-the relation of the pin to the slot in the roll. In the drawings, the numeral l indicates the back of the cabinet, and numeral 2 the bottom thereof. The bottom .and back are formed in one piece, or section, as best shown in Figure 4. The bottomis pressed outwardly and downwardly to form a depression ,3 having slots t and arcabinet go ranged as shown. The slots are so positioned that dust or dirt rolls downwardly and outwardly through the slots. The depressed portion 3 is elongated, as shown in Figure 3, in a direction transverse of the cabinet or parallel with the axis of rotation of the feed rolls and the supply roll. A forward portion of thebottom 2 is bent upwardly as at 6, so that its'upper edge is arranged close to a feed roll I suitably journaled on an axis or shaft or trunnions 8 in a manner to be hereinafter described. This feed roll is grooved as at 9, and the upwardlyyoutwardly slanted portionfi has attached thereuntosuitable fingers l0 which-cooperate with the groove to direct the paper downwardly and outwardly. The upper edge of the back has an inturned-or forwardly'directed horizontal flange i5, which-in turn has at its forward edge downwardly turned flanges l6 spaced apart to provide an opening [1. Below this cut out portion Hand below the flange I5 is arranged a keeper l9 with which the-hook 18 of a lock generally indicated at 49' engages to'secure the cover.- The locking mechanism is not described because it is of well known construction, but it will be understood when the -keyis inserted in'the lock and the lock is rotated, the hook I8 isswung from the position shown in Figures 2 and'9, for example, to a release ..position which allows the front cover to be swung forwardly and downwardly below the bottom 2 to act as a shelf. The frontccover is substantially formedof three parts, one part of which forms the top 2! and the front "22, the other ;two parts forming the sides respectively indicated at 23, .24, all parts together forming a four-sided compartment. The hinging means includes a pair of L-shaped brackets arranged one at each side of a pair of upright journaling plates later to be described, said brackets being indicated by numerals 25. Each bracket rests on the top of a flange of a corresponding feed roll journaling plate and each has an upturned outer portion through which passes a pivoting pin 26, one pin being attached to the side 23 and the other to the side 24. A split key 21 secures the pin 25 against outward movement. The pins are introduced into openings of the brackets from opposite sides by movement toward one another after the sides of the device have been preliminarilysprung outwardly. The straightening of the previously sprung sides 23, 24 tends to hold the pins in position. The placement of these pins in relation to the inner and outer sections is such that when the cover is swung outwardly and downwardly to its lowermost position (while the inner section hangs on a wall), the outer edge of the knife portion, later to be described, engages the bottom wall of the cabinet as a stop to limit rearward swing. In such a position the cover forms a're'cep'tacle for a temporary placement of the supply roll. From this position the end of the paper can be started or threaded through the rolls, and then the supply can be lifted and placed in position within the cabinet. extending part of the bottom of the front 'wall 22 of the cover, and is best shown in Figures 1, 3 and 4. This extension is indicated at 30 and it has paper-sighting openings 29 therein, as best Z is projected from the feed roll 1. The front 22 is bent to provide a bead 32 around which the paper passes to a point beneath the knife. The bead 32 constitutes means for holding the projecting end of the paper, remaining after tear-off, away from the knife so that the fingers or thumb can be introduced between the inner side of the knife and the paper, for grasping the paper to pull out more of it. As shown in Figure 4, the supply roll 35 is so supported that it simultaneously rests upon the feed roll 1 and upon supporting means, specifically upon a pair of supports, each indicated by the numeral 35. These cross sectionally L- shaped supports are held by a singlefastening device indicated at 31, the supports being swingable about this fastening device and their lower ends being in contact with the bottom of the inner section of the casing. The weight of the roll tends to hold them in that position. Due to the inclination of the ledges or movable supports 36, the paper tends to roll constantly toward the feed roll I, no matter how small the roll becomes. This makes for even pull-feed action. It is equally emcient in any cabinet in which the paper supply is in roll form, whether it be of pulltype or crank-operated type of feed. Moreover, there is no intention to entirely limit the invention to supports such as 38. The provision of the elements 35 and the arrangement by which they are separately adjustable provides means whereby leveling of the supplyroll in relation to the dispensing roll can be obtained conformably to variations in winding irregularities in the supply roll, and whereby the The tear-off knife is a downwardly, forwardly degree of contact pressure of the supply roll with the dispensing roll can be varied conformably to the changing weight of said roll resultant from use. The construction for the journaling support for the rolls and for the mounting of a stop mechanism includes two upright plates respectively indicated at 39, 40.. It is to the inner sides of these plates that the inclined supports 36 are attached and it is between these plates that the supply and feed rolls are disposed. Each plate (see Figure 2) has at each of three margins an outwardly directed flange, the flanges pointing toward the sides 23 and 24 of the cabinet. These elements 39, 40 are spaced to provide lateral chambers respectively indicated at 42, 43. The top flanges for the plates are respectively indicated at 44, and these flanges are cross-connected by a bar 43 held by suitable screws 41. The rear flanges are indicated at and the bottom flanges are indicated at 5|. The bottom flanges 5| are spot welded to the bottom 2, as are the flanges 50 spot welded to the rear wall I of the cabinet. Key-hole slots 52 are provided in the rear wall so that the cabinet can be hung on suitable fastening devices (see Figure 3). This flanged and welded structure braces the vertical and horizontal parts of the inner section and provides an unusually strong cabinet, by the use of a minimum amount of material. As before stated, the feed roll is suitably journaled by means of a, shaft 8, and the plates 39, 40 form part of the journaling means, the said shaft or equivalent trunnions passing through bearing collars punched out of the plates 39, 40. These plates also have slots 55 in which are journaled a, presser roll 56 pressed into engagement with the paper 51, as best shown inFigure 4. Springs 58 suitably secured, as best shown in Figures 1 and 5, yieldably hold the roll in the positionshown in Figure 4. Reverting to the feature wherein the attendant is forced to properly place the roll, and by which proper feeding action is interfered with when a roll of shorter axial length is placed in the cabinet. Referring to Figures 3 and 4. The axial length of the supply roll is about equal to the horizontal distance between the plates 39 and 40 and the supply roll has an inwardly directed diametric slot 60. Referring to Figure 4. A pin 62 projects inwardly from the plate 40, this pin being slightly shorter than the axial depth of the slot 60, said slot being of sufficient width so that its sides can rest and slide on the pin as the roll is moved inwardly in the direction of the arrow A of Figure 4 when servicing the cabinet. It is noted that only one end of the roll has a slot 60 so that unless the slot is arranged on the same side as the pin (of which there is only one), the roll cannot be introduced. Moreover, whenthe roll is placed so that the slot is on the same side as the pin registration must be obtained between the slot and the pin before the roll can be moved inwardly. This is done while the pin is in register and while the walls of the'slot engage and move along or are guided by the pin. Referring to Figure 4, it is noted that the diameter of the full roll represented by the letter Z is greater than the distance X from the inner side of the pin 62 to the forward edge of. the bar 46 so that a roll of full diameter cannot be dropped in from the top. Also, the diameter Z is greater than the distance Y from the bottom of the pin to the top of the presser roll 56 so that the full roll cannot be introduced in this directhe knife. tion. If an attempt is made to use a roll of a diameter Z, but of a length S which is slightly less (see Figure 3) than the distance between the end of the pin and the inner side of the plate 39, then the roll will not be properly supported by the elements 36. The reason is that the inner edges of these elements are so spaced (see Figure 6) that although a roll of such shorter length can bridge and rest on the supports, it will move axially during feeding and one of its ends will slip from one of the supports while its opposite endis held, and the axis of the roll will assume a non-parallel relation with the axes of the feed rolls to cause jamming. In the front view the roll of proper length is shown in dotand-dash lines and the roll of improper length is shown in two dots-and-dash lines. Right placement gives the right curl to the paper under It is seen that the pin and slot arrangement prevents wrong placement, and that the pin and slot in conjunction with the support arrangement ,makesit very inconvenient, if not impossible, to get a proper operation when a roll of a lesser length is used. It is noted that this device requires a dispensing roll of a predetermined axial length which in length is substantially equal to the horizontal distance between the two upright walls of the chamber. The pair of spaced supports is adapted to only receive and support by its opposite end portions a supply roll which is of the above mentioned predetermined am'al length, and these supports are adapted to sup-port said supply roll in proper feeding relation with the dispensing roll 'whereby "if the supply roll is shortened to a certain degree it will fall off of the supports'and proper feeding cannot occur. In this case if the length of the roll is shortened by an amount equal to the depth of the slot 69, this falling off will occur. Therefore, in order that proper feeding take place the roll must be of a predetermined length, and if a very much shorter roll is used it will fall olf of the supports. Another feature which facilitates introduction of the leading end of the paper between the rolls, is the cut-out reduction in diameter of the middle part of the presser roll 59. This cut out portion is indicated at 95. Two or three human fingers can be introduced into this reduced portion of the presser roll, the tips of the fingers at this point pressing the paper inwardly toward the meeting point of the roll. This can be accomplished whether the supply roll is pocketed in the outer casing or cover when open, or after the supply roll has been placed within the cabinet by sliding past the pin 62. In either instance the paper is preliminarily laid on top of the presser roll and then the fingers are curved and the paper is pressed into the reduced portion with the fingers curved, their tips turn or move the roll to move the paper toward and into the bite or meeting points of the rolls. After the paper is brought through the rolls its forward portion is pulled so that it lies in the receptacle or cover and then as the cover moves to its closed position the end of the paper falls below the end of the cabinet, in proper relation to the tear-off blade. Referring to Figures 3 and 4. Attached at one end of the roll 7 between the plate 40 and the side 24 is a feed roll operating disk 70 which projects through slots H respectively in the front 22 of the cover, and in a finishing plate 13. The plate is suitably secured by fastening devices and is has an outwardly, downwardly bent portion I4 which overlies the tear-off knife 39. It will be understood that this disk is :used for starting the the stop mechanism in stop 'position. The only essential difference in the positions of these figu-res is the positions of the slide. In Figure 1 the slide is in its uppermost .position withits cushion engaging the flange 44, and in Figure 5 the slide is in its lowermost position with the vacuum cups invacuum attached relation. .It will be understood that when the mechanism is-operated from its position in Figure I the slide is lowered even below the-positionshown in Figure 2 to primarily compress the'cups, and then the resiliency of the cups 'moves the "slide slightly to the position shown in Figure 5. The aXleor trunnion f the feed roll 7 pro- J'ects laterally through the plate 39- and has attached thereto asmall spur gear 8 9. This gear meshes with a second larger gear suitably journaled on a screw'82 carried by the plate 39. Suitably attached to theouter face of this gear BI is a stop arm 83 which is adapted to engage the outer side of a stop flange 95, which is part of a slide 99. This flange is part of a channelshaped element having an opposite flange 86 slidingly engaged with the fiange 81 of a bracket 88 suitably secured to the outer side of a plate 39. The channel element is suitably secured to a slide element generally indicated at 90. The inner face of theslide lies against the outer face 'of the plate 39 and the inner upright edge 9| of the slide is engaged with another guide member 92 preferably struck out of the plate 39 and this element 92 and the flange or element -87 guide the slide on the inner side. It will be seenfrom the dot-and-dash line position of Figure 1 that as the arm 83 moves in clockwise direction the slide is lowered. This is accom- "plis'hed by means of a link later to be described, and in the dot-and-dash line position shown it will be noted that when the arm 83 moves in counter-clockwise direction, which it is now supposed -to be doing, the principal thrust of the slide isagainst the element 81, while there is a tendency to rock the upper part of the slide to therightagainst astrike-out guide 93, which lies under a part of a timer-supporting bracket 94, suitably secured to the outer face of the plate 39. The bracket is arched to receive the guide 93, and the bracket 94 has a portion 95 overlying the upper part 96 of the slide 99, and the slide is held between this portion 95 and the outer surface of the plate 39. Three guiding elements are thus provided for the slide, one adjacent its upper end, one near its bottom, both on the same side, and one near the middle on the opposite side. The first and last mentioned guides are struck up from the plate, the lowermost guide is detachably secured by bolts. In order to make room for the struck out middle guide the bracket is bowed outwardly, as shown, and this bowed portion merges into the attached portion of the bracket and into that portion which overlies the slide and prevents its outward movement from the upright 39. The slide is moved to stop position and released for independent movement away from that position by means of a link 91, slotted as at 98. A pin 99 passes through the slot and thus rotatably and translatably attaches the link to the gear 8!. The opposite end of the link is pivoted to an outward extension I of the flange 85, and a split key IN and a suitable washer secures the link in pivotal relation. The upper end of the link is attached to one end of a spring I02, the opposite end of which is attached to a struck-out portion of the flange 44, as best shown in Figure 1. This spring, it will be seen, acts through the link to raise the slide, as soon as it is released by the link, so that when the parts are positioned as in Figure and the vacuum is released the link is free to slide upwardly under the action of the spring. I At the upper part of the slide is an extension I03 to which is attached a vacuum cup I04. The bracket or plate 94 has a shelf I05 upon the top of which is mounted another vacuum cup I06 which cooperateswith the vacuum cup I04 in the manner to be described. This vacuum timestop device is not herein claimed per se, inasmuch as it is covered in other pending applications. It will be understood that an intake opening I08 admits air within the cups so that the vacuum is gradually released, and the rate of air entry can be adjusted by means of a screw I09, yieldably held for adjustment by means of a spring H0 (see Figure 3) acting on the screw head III. It can be seen by an inspection of Figure 1 that the stop mechanism is, in this instance, arranged at a level above the feed roll, so that as the feed roll rotates the slide is pulled downwardly against the action of the spring I02. During downward action the link causes the flange 86 to be pressed against flange 81, the spring also acting at this time to press the slide rearwardly in the same direction against its two guides. Rocking tendency towards the right is prevented by the guide 93. When the slide moves upwardly from its position in Figure 5 by the action of the spring, the link now being loose and the slot sliding on the pin, the spring continues to keep the slide against both of its guides 81 and 92. This is a valuable and eflicient arrangement of the parts not exactly like any other mechanism for the same purpose, known to me. The mechanism is particularly adapted for reducing noise, and for allowing an arrangement above the level of the feed roll, and for allowing an accessible positioning of the timer at the front so that adjustment can be easily accomplished. The three-guide arrangement, with the link'and spring acting to hold the slide anti-rattle relation to the two guides is a valuable construction. We claim as our invention: 1. A dispensing cabinet having a back and side walls, a dispensing roll journaled in the side walls, a pair of supports, each carried by a side wall, means pivoting each support to its side wall so that each can be separately adjusted, said supports extending forwardly and downwardly toward and to a point below the level of the bottom of the dispensing roll, said supports adapted to be bridged by and to support by its outer ends a supply roll so that said supply roll constantly engages the dispensing roll by gravity action, said supports being adapted to be adjusted by moving their outer and lower ends upwardly toward the measuring roll, whereby leveling of the supply roll in relation to the dispensing roll can be obtained conformably to variations in winding irregularities in the supply roll and whereby the degree of gravity contact pressure of the supply roll with the dispensing roll can be varied conformably to the changing weight of the roll resultant from use, and whereby these adjustments can be made with a minimum of forward movement of the supply roll. 2.
