Matter enclosed in heavy brackets [II appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.
This invention relates generally to devices for dispensing rolls of paper, such as towelling rolls, wrapping paper rolls or the like.
In winding paper rolls of the above types, different mills wind the paper web on mandrels of diiierent diameters, whereby the axial holes provided by the mandrcls vary accordingly in size. Generally the rolls have a center core of cardboard or like material, but this may be omitted in some instances. Conventional dispensers for such paper rolls consist of means for engaging and supporting the ends of the roll for rotation about its axis. With rolls having different size axial openings, it is dithcult with such dispensers to maintain aiignrnent between the axis of the roll, and the axis of the roll supporting means.
It is an object of the present invention to provide a roll dispenser in which the centering means is effective for rolls having axial openings of different diameters.
It is a further object of the invention to provide a paper roll dispenser which centers the roll on the desired axis of rotation without engaging the inner surfaces of the core.
Another object of the invention is to provide a paper roll dispenser which establishes a driving relationship between the supporting means and the roll, as well as to effect automatic centering.
Another object of the invention is to provide a paper roll dispenser in which all of the paper can be removed from the roll without interfering with the desired centering action.
Additional objects and features of the invention will appear from the following description in which the preferred embodiment has been set forth in detail in conjuntion Willi the accompanying drawing.
Referring to the drawing:
FIGURE 1 is a plan view illustrating a simple type of paper roll dispensing device, with a paper roll applied to the same.
FIGURE 2 is an end view of the paper roil, showing one arrangement of slots.
FIGURE 3 illustrates one of the devices for engaging and supporting the roll, looking towards that side of the device which faces the roll.
FIGURE 4 illustrates the same device as in FIGURE 3, as viewed from the right hand side of this figure, a portion of an engaged paper roll being illustrated in dotted lines.
FIGURE 5 is a view like FIGURE 2 but showing another arrangemcnt of slots.
FIGURE 6 is a view like FIGURE 3, but showing another embodiment adapted to cooperate with slots as shown in FIGURE 5.
FIGURE 7 is a view like FIGURE 4, showing the embodiment of FIGURE 6.
FIGURE 1 illustrates a paper roll 10, which may be of the type commonly marketed for use as paper toweiling. This roll is formed by a web 11 wrapped about the cardboard or fibrcboard core 12. In same instances the core may be omitted. The simple type of dispensing device illustrated in FIGURE 1 consists of devices 14 and 15 Re. 25,828 Reissued Aug. 3, 1935 which engage and support the ends of the roll and which in turn are rotatably carried by the panel 13.
At least one of the devices 14 and 15 (eg. 15) is constructed as illustrated in FIGURES 3 and 4. Thus in this instance the device consists of a fiat metal body iii which is rotatably carried by a pin 17, on the supporting arm 13a. At least three finlike spurs 13 are carried by the body 16 and extend generally in planes parallel to the axis of rotation. In the particular construction illustrated, three fins 18 are provided, and the plane of each fin is coincident with the axis of the pin 17, as shown in FIGURE 3. Also the general angular spacing of the fins is equal, although this is not essential.
The corresponding end of the paper roll 19 is shown in FIGURE 2 and is provided with a plurality of angularly spaced slots 19. These slots have the some angular spacing as the fins 18, but they have a depth and radial extent considerably greater than the width and radial length of the fins. This proportioning is illustrated in FIGURE 4.
It will be evident that the fins 13 will be accommodated within the slots 19 in the manner illustrated in FIGURE 4, with portions of the body 16 engaging the end face of the roll. Because of the proportioning. the fins wili not contact either the outer end or bottoms of the slot. In other words, only their side faces are permitted to contact the side faces of the slots. Because the device of FIGURE 3 has three tins engaging in three siots, there is an inherent centering action which makes it necessary for the axis of the roll to coincide with the axis of rotation of the device 15 before the fins 18 may be accommodated within the slots.
The inherent centering action described above is a distinct features of the present invention. By virtue of this automatic centering action, which is independent of engagement with the inner surfaces of the core 12, rolls having axial holes of different diameters can be applied Without changing the device i5. Furthermore because the fins 13 do not bear upon the outer ends of the slots 19 for centering. the arrangement is independent of the rcmoval of paper, and all of the paper can be removed without affecting the centering action.
As indicated above. either one or both of the devices 14 and I5 may be constructed to cooperate w th the roll in the manner illustrated in FIGURES L4. However, if desired, one of these devices may be of simple construction following conventional design, with portions adapted to project into the corresponding end of the core 12.
It will be apparent that the device 15 described above not only has self-centering action but also establishes driving relation with the roll. Therefore such device 15 can be connected with a mechanism such as is commonly used in paper roll dispensers for limiting or controlling the length of webbing being Withdrawn. Also it may be employed in conjunction with ratchet or like means, to prevent back rotation of the roll. In FIGURE 4 I have shown a spring washer 20 interjoined between the body 16 and arm 13a. This washer may have struck-out spring tongues that are normally compressed to thereby provide some friction or drag tending to resist rotation.
FIGURES 57 illustrate another embodiment of the invention in which four fins or spurs are employed instead of three. Thus in this instance one end of the roll is provided with slots 21 that are oliset from the axis of the roll. The device 1521 can consist of a body 22 provided with three projecting finlike spurs 23. These fins have a positioning and angular spacing corresponding to that of the slots 21. The pivot pin 24 is shown for rotatably supporting the device 15 upon the arm 13a.
FIGURE 7 illustrates how the device of FIGURE 6 engages within the slots 21. Here again it will be noted,
3 that the fins do not bear upon either the bottoms or the ends of the slots.
