ROLL PAPER DISPENSER Filed Sept. 9, 1959 I 1". I l'- k\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ i E/nardens flro/s/rammer' By his attorneys United States Patent M 3,050,224 7 ROLL PAPER DISPENSER Einar Jens Drolshammer, Folke Bernadottesgate 31, Moss, Norway Filed Sept. 9, 1959, Ser. No. 838,873 3 Claims. (Cl. 22538) The present invention relates to paper roll holders and more particularly where one or more rolls are rotatably joumaled for the unrolling of the paper. In such holders, the journaling is in the side walls of a drawer or closed container and the paper is drawn out through a slot in the front of the container where the paper is torn off with the aid of a tearing edge or knife. One of the problems arising with these holders is the tendency of the paper web to slide back after an end has been torn off so that the new end cannot be gripped by the fingers. Clamping means have heretofore been provided to assist in the tearing off operation to avoid this but this complicates operations when a new roll has to be threaded up through the clamping means to the knife. If two or more rolls are provided, one above or behind the other, there is difiiculty in threading up a new rear roll. It has been necessary to remove the front roll to replace a rear roll. Furthermore, there has been trouble to bring the web from a rear roll under the roll or rolls in front of it. The object of the invention is to avoid the difliculties above mentioned. It is characteristic of holders made according to the invention that there is a narrow curved guiding passage with upperand lower plates between which the paper web is guided to the knife slot, the lower plate covering the lower part of the roll. The free inner end of the lower plate serves as a braking plate. The curved guiding passage provides easy threading up and prevents the paper web sliding back. No clamping means are needed and the web from a rear roll can be curved under a fi'ont roll without contacting the latter.

In the drawings the figure is a view in vertical longitudinal section through the middle and front portions of a paper roll holder made in accordance with the invention showing two rolls, one behind the other.

The example shown in the drawings is a paper roll holder having a bottom 20 and side walls 21 with a front having profile plates 2, 3, 4. These profile plates are so spaced that S-shaped slots 5 are formed therebetween. Pivoted tearing knives 6 are arranged in the slots 5. Paper rolls 10, 11 are journaled at the side walls 21 on axles 12 in removable manner. The above features have been known heretofore.

Novel guiding passages are provided for the paper webs 8 and 8' drawn from the front and rear rolls 11 and 10 respectively. These passages comprise upper and lower plates 14, 16' and 14' and 16 for the front and rear webs respectively. The novel passages are curved and the paper webs 8, 8' passing between the plates are led to the knives 6 in the slots 5 at the profile plates. The upper and lower plates are so close together as to ensure that the paper web will always be contacting a major area of one of the plates if the web relaxes from movement in the guided direction, thus preventing the web sliding backwards towards the roll when a piece of web is torn off. The inner ends of the lower plates 16, 16' are extended as brake plates 9, 9' respectively of a known type. The rear or free ends of the brake plates lie against the paper rolls 10, 11 and each lower plate covers part of the lower half of its. roll. The 8 curve of the passage 14', 16' for the rear roll 10 is large enough to clear under the front roll and passage.

Assuming it is desired to replace the rear roll 10 by a new roll of paper, the new roll is placed with its axle 12 journaled in the side walls 21. The palm of the hand is laid on the top of the roll and the roll turned counter- 3,050,224 Patented Aug. 21, 196 2 clockwise as viewed in the drawing. The web 8 automatically enters the gap formed by the passage between the plates 14', I6 and by gravity will rest against the lower plate 16'. Continued rotation of the roll will cause the curved passage to guide the end of the web to the knife 6 for that roll. It will be seen there is no necessity for removing the front roll 11 to thread up or use the back roll because of the enclosed curved passage. Threading up the front roll 11 is done in the same manner.

When paper is drawn from the web 8 or 8 by hand through one of the slots 5 in the front of the holder, i.e. paper is fed out, the hand pushes the knife 6 inward to get hold of the free end of the web. However, the movement of the knife inward would heretofore tend to slide the web back into the holder, toward its roll. This meant that the end of the web could not be gripped by the fingers. This was the reason clamping means had to be provided. No clamping mechanisms are needed in the holder because the novel guiding passages are curved and exercise friction on the web. These passages and the braking plates 9 prevent sliding back. The S-shaped curve is especially useful for this purpose. The curved passages are effective in preventing the knife 6 from pushing the web 8 backwards into the passage when the knife is pushed inward.

What is claimed is:

1. A roll paper dispenser comprising a container having side walls and a front wall, there being one or more slots in the front wall for withdrawal of paper, and a tearing knife associated with each slot, there being means associated with side walls to journal one or more rolls of paper, in combination with a narrow curved web-guiding passage between and leading from each roll of paper to its slot in the front wall adapted to control the web between those points, each such passage comprising a curved upper and a curved lower plate so close to each other as to insure that the paper web from the roll always contacts the major area of at least one of the curved plates when the web relaxes from the movement in the guided direction, the narrow curved guiding passage between plates thereby preventing the Web from sliding backwards.

2. A roll paper dispenser for a plurality of rolls spaced from the front wall and arranged one behind the other comprising a container having side Walls and a front wall, there being a slot for each roll in the front wall for withdrawal of paper from the front wall and a tearing knife associated with each slot, means associated with the side walls to journal the plurality rolls of paper in combination with a narrow web-guiding passage between and leading from each roll of paper to its slot, the passage thus controlling the web all the way to the slot, each such passage being 8 curved and comprising an upper and lower plate, the lower plate embracing the lower part of its roll of paper but not the upper part and adapted to act as a brake on the roll against turning in the wrong direction, said lower plate guiding the web from the roll direct to the web-guiding passage, the upper and lower plates being mounted so close to each other as to insure that the web contacts the major area of at least one of the plates when the web relaxes from movement in the guided direction, the narrow S curved sliding passage preventing the web from sliding back.

3. A roll paper dispenser for a plurality .of paper rolls comprising a drawer having side walls and a front wall, there being separate slots in the front wall for the withdrawal of paper from each roll, means associated with the side walls to journal the plurality of rolls spaced one behind the other from the front wall in combination with a narrow web-guiding passage from each roll of paper all the way to its slot, each such passage comprising an upper and lower plate closely spaced together so that a major area of at least one of the plates is in contact with the web when the web relaxes from the movement in the guided direction, the lower plate of each passage being extended rearwardly around the lower half of its roll of paper, characterized in that the web-guiding passage of each paper roll behind the front one is S shaped and clears under the lower plate of the front roll, the lower plate of each web-guiding passage being extended rearwardly to surround only the lower plate of its roll, thereby acting as a brake against the roll turning back when the web relaxes and the passages preventing the webs sliding back; whereby the new roll can be threaded up by turning the roll.
