2 Claims. (01. 242 55.5)

1 This invention relates to a cabinet for dispensing sheet material such as, wrapping paper,

waxed paper, paper toweling, cellophane, foil,

etc., from a supply roll.

It is an object of this invention'to provide a cabinet from which the sheet material can readily be withdrawn and severed in any chosen length. It is another object of this invention to provide a cabinet wherein the sheet material will always be available for easy grasping; It is still a further object to provide a cabinet which may be used either when supported on a horizontal surface or on a vertical surface, andmore particularly, a cabinet in which new rolls may be placed when the cabinet is supported ona vertical surface without the roll falling out of the cabinet. Other objects and advantages of the invention will be evident from the following description and accompanying drawings wherein:

Figure l is a perspective view of the dispensing cabinet,

Figure 2 is a rear elevation of the cabinet,

Figure 3 is a perspective view of the cabinet of Figure 1 showing the cover in open position and the roll removed,

Figure 4 is a side elevation of the cabinet showing parts broken away,

Figure 5 is a fragmentary perspective view of the cabinet showing one of the bearings for supporting the roll,

Figure 6 is a front elevation, partly in section, of the supply roll,

Figure 7 is a section taken along the line 'I--"I of Figure 1, and

Figure 3 is a side elevation of the cabinet showing the cover open of the dispensing cabinet supported on a vertical wall.

The dispensing cabinet I is preferably made of metal and comprises a base 2 andcover 3. The cover is hinged by pivots 4 and 4' to the base. A passageway 5 between the front portion 6 of the cover 3 and a guide I extending along the front edge of the base 2 allows the sheet material within the cabinet to be withdrawn when the cover is closed as shown in Figures 1, 4 and 7.

The cover {includes two side walls I and II and convexly curved top wall I2. The front edge of the top wall I2 is preferably provided with serrations to form a serrated cutting edge I I3. The cutting edge I3 is also preferably turned upward, as shown in Figure 4, so that the serrations will not mark the sheet material as it is being withdrawn.

The base 2 includes a bottom wall I5, and side walls I6 and Il front wall I8 and rear wall I9. Extensions and 2| integral with the side wall serve as brackets to carry at'their ends the pivots 4 and 4' for supporting the cover. Front wall IB carries guide I at the top thereof and in the embodiment shown guide 1 is an extension integral with the front wall I8. The leading portion 22 of the guide is convexly curved, the center portion 23 generally flat and lying in a plane generally parallel with the base, and the trailing portion 24 generally flat and parallel to the front portion 6 of the cover wall. The side walls l6 and I! have inwardly offset portions I6 and II which are shaped to form partial bearings 25 and 26 for rotatably supporting the supply roll 29.

The supply roll 29 comprises sheet material 30, such as waxed paper, wound on a hollow core 3| which may be made of paperboard. In each end of the core a metal flanged sleeve 32 is provided comprising a short sleeve 33 secured by projections 34, as shown for one end in Figure 6, to the core 3I and a circular axial flange 35 projecting beyond the end of the core.

The supply roll 29 of continuous sheet material is placedin the dispensing cabinet by disposing the flanges 35 of the flanged sleeves 32 on each end of the roll in the bearings 25 and 26. It is a feature of this invention that these bearings are partial bearings which are so positioned as to have portions 36 and 36' of the arcs thereof extend beyond the vertical axis of the roll to support the flanges 35 by gravity so that they remain in place when the cabinet is supported on a vertical surface. (See Figure 8.)

To further insure-that the roll remains in the bearings a boss 31 associated with bearing 25 extends within the flange 35 whereby the flange is secured against transverse movement between boss 31 and the bearing 25. (See Figure 5.) The boss 31 is preferably formed from a strip of metal 38 welded to offset wall I6 and has a pair of U-shaped portions 39 and 39 which are adapted to fit over the bearing 25 and the flange 35. Only one bearing is provided with the boss since the flange must be inserted axially into this bearing when the roll is placed in the cabinet.

When a roll of sheet material, as for example, waxed paper, has been placed within the cabinet and the flanges 35 at each end thereof are resting on bearings 25 and 26, the free end of the web is drawn over guide I and the cover 3 is swun over the base 2 to close the cabinet. A latch which cooperates with a keeper 4| is provided to retain the cover in closed position. The keeper 4! is a slot formed in an offsetfiange 42 on the rear wall [9. The latch 46, made preferably of a resilient strip of metal, is secured to the inside cover as by rivets 43 and is providedwith a dent 44 at its end and a button-like protuberance 45 at its center. Associated with the latch 40 is a protuberance 4B on the'cover'3 which serves to facilitate the lifting of the coverwhen unlatched. This protuberance is preferably formed from a portion of the cover topi'dvide an opening 41 through which button 45 is accessible for releasing the latch 40 by pressing the button.

After the cabinet isdocked closed, sheet material may bewithdrawn from the "cabinetand severed inany desired length bytearing along the serrated edge I3; A brake member is provided to prevent the supply-roll from unso that its free end frictionally'engages the outer surface of the flange-35w The brake member 50a1soserves to retain the roll in the bearings.

Though obviously a brake may" be provided at each end of the roll it has beenfound" that only one located at the bearing not having tl'1e 'boss 3fwill serve the twofpurposes; f The simplicity of construction and the dual" function of'the brake member is a marked improvement over the art, such as U. S. 2,434,194.

Even though the roll is braked as "described,

the leading edge ofthe paper 'upori s tanding may "tend to withdraw-into the cabinet'due to a tend l ency for the outer layerofthe web to 'pull back off the roll. "To' overcome this tendency grippers and 56'are provided whicharet adapted to engage 'the' paper as it crosses guide I. fThese grippers are formed of 'resilient"springinetal jiingers which are secured to th elinside of the cover at 5'1 and 58 as by welding. The fingers are positioned and arranged so that their free "ends frictionally engageth e web as itorferlies or moves over the guide 1;" (See Figures and I.) Although two grippers are'shownan'y suitab e u b m be ew P *efi qt'p 'e fi Y without interfering with'the' 'ease ofwithdrawing the web. V I

When the dispenser is used' for disp ens'ing waxed paper, which isinherently slippery, it is difficult to grasp the web only from the underside as in' the dispenser shown in the aforeme 'tioned U. S. Patent 2,434,194. I'0 -facili'tate'igrasping theweb, a cut out area 60 is'provided in the guide 1 immediately above which, and in alinement with, isprovided an "opening 5] in the "curved top wall l2 ofthecover. Bythisarra'ngement a person may-easilygraspthewebfb'etween his fingers and then withdrawthesheetmaterial The opening in the cover may extend through the edge [3 but it is preferred to have an uninterrupted and rigid cutting edge as shown for purposes of uniform tearing.

5 Rigidity of the serrated cutting edge [3 is further enhanced because it is turned upwardly as previously described. Additional rigidity is also obtained by an indentation 62 in front portion 6 of the cover since the stiff edges of the in indentation reduce flexing. f the cover. This indentation 62 "further serves to-receive a suitable label 63 for the dispenserwhich'; because of the indentation, cannot be accidentally brushed off.

When the dispensing cabinet is to be used on a table top or other horizontal support, it rests H on rubber feet 65. When it is hung on a wall 66, itmay be hooked through openings 6'! by hooks 68 in the bottom wall l5 of the base 2.

'When a roll is in the cabinet and the cover latched, sheetfinaterial may be withdrawn by "grasping that portion of the free end of the sheet material exposed in the opening H between the "fingers and pulling out as much material as de- 25 sired. v( See Figure 7.) The amount withdrawn ean thenbSeiiered by-"tear ing the'w i thdrawn portion along [serratedfedge' I3. "(Figure 1.) -Afte'r the desired material has been' severed; an-

other portion of the rn aterial will be'exposed it) inopening 1| because of the operation ofbrake 5 member 5lland grippers 55and 56. Hence,"ma-- terial canreadily befirem'oved from "the cabinet -without further manipulation untilthe roll is exhausted. V V I as To insert a ne'w-roll;-whether the'cabinet is 'fv'ertically or horizontally supported; "the button 45 of'latch 40 isdep'ressedand the"cove'r swung open by grasping the protuberance 46. Withthe cover open'thebrake' member 50 is movedbut of """hence the flange at this end of'the roll may be lifted out of the" bearing. W The flange resting inbearing 25"n ay now be withdrawn" axially.

K The newroll is'placed inthef' bearings 25an'd" 2'6 4 in the reverse order, mans, flange 35 on'on'e end of the roll is axially inserted in bearing2 5 around 4 b o ss '3],"andthe ffiahge iit the other end is laid iribearingZG." Sufilcient material is unrciied so '""'that the'fre'e end"overlies"the" guide 1. The 50 coverisnow swung closed'andthe'latch 40 will automatically lockl Thef'gripper's 55 and 55 will engage the freeend of "the'mate'rial'and the brake "memberwill'lioldth'e" end of the roll resting in bearing 26 in" place. The cabinet is again ready for use as described above.

' The'specific'- constructionherein described is given as an illustrative embodiment ofthe invention' and it is to bhnd e'rstood that other modifications and changes are intended to be 60 included within the scope of theabpendea claims.
