M0025 W Arrow 5r i afenteci june Robert; C.;Moore;,;Long lslanami" r 28, 1-929. -Bdt of the'character described which meets all'ptac hradnyitam me rmm the remamaem the-femaimihg egg i'other wordsgfmelpaipe web is scored along the diverging lines 2 am 1* accomplished, an adhesive is applied to the opposite ends of the roll as at 4 and to bind the successive convolutions of the web firmly in place so that the roll cannot unroll or loosen. The application of adhesive may be by a sponge or otherwise, momentarily pressed against the ends of the roll or the ends of the roll may be dipped in an adhesive. This is optional. However, when the roll is formed, the paper at its opposite ends will be adhesively secured so as to maintain the web in rolled condition. The adhesive should not, however, extend beyond the score lines 2, between which the paper strip la is adapted to be removed by tearing or severing along such lines.

In forming the paper roll, I preferably wrap the web about a suitable core 6, shown in Figures 6 and 4. This core may be and preferably is in the form of a hollow tube, rod or dowel of small diameter which serves the purpose of conventionally starting the roll and also serves to space the opposite end portions lb-lc of the roll apart when the greater portion of the paper has been torn therefrom and until the roll is exhausted. Although the spacing of the score lines 2 from the opposite ends of the roll may be the same from :both edges of the paper web, I preferably make the spacing at one side of the web greater than at the other side in the interest of economy, the larger spacing being sufficient to aiford a, firm anchorage between the roll and the dispensing plug as presently explained.

The roll 3 is adapted to be housed within a tube 1 of metal, plastic or any other suitable material, one end of which is adapted to snugly lit a reduced portion 8 on the rear end of the pencil body 9. The engagement of this end of the tube with the portion 8 firmly secures these parts together in a, detachable manner although they may be adhesively or otherwise secured together if desired. The upper end of the tube is adapted to rotatably receive the reduced portion ID of a rotatable finger piece ll, provided interiorly with a cavity l2 into which one end portion lc of the paper roll 3 may be received with a snug fit.

The exterior of the finger piece II is circumferentially toothed, as indicated at l3, to form an annular ratchetand with this ratchet is adapted to cooperate a spring finger l4 formed upon a pawl spring l5, as shown best in Figures 1 and 5. This pawl spring may form a continuation of a pocket clip l6, as shown, or may be made separate therefrom'if desired. The clip and ratchet spring are held in place upon the tube by rivets I! or otherwise. The purpose of the ratchet is to limit rotation of the finger piece to that direction appropriate to unwind the. dispensable portion, 1. e., the strip la, of the paper web from the roll and project it through a longitudinal slot I8 in the side of the tube. This slot is preferably cut at an angle as shown in Figure 4.

The paper roll is adapted to be introduced into the tube by withdrawing the finger piece II from the upper end of the latter. Before placing the roll in the tube a small portion of the strip Ia, between the lines 2, should be torn from the roll to provide it with a loose wing extending therefrom. One end portion l0 of the roll is then pressed into the socket I2 of the finger piece and the roll and finger piece are then inserted into the upper end of the tube until the reduced portion In of the finger piece comes to a seat within the tube.

If the finger piece is thereafter turned in the direction permitted by the ratchet, the free end of the wing on the paper will engage with and enter the slot I8 and be projected therethrough and, if rotation of the plug is continued, more and more of the paper strip will be torn from the roll and projected through the slot. Alternatively, that portion of the paper strip which is projecting through the slot, may be grasped and withdrawn therethrough. This operation will contemporaneously cause consecutive portions of the strip l a to be torn along the secored lines 2, so that it may be dispensed through the slot [8.

When a sufiicient amount of paper has been withdrawn for particular memorandum in mind, the thus dispensed length of the paper may be torn off from the remainder of the roll at the edge of the slot I8, which is preferably sufficiently sharp or rough to form a satisfactory tearing edge. After this dispensed part is torn away, that portion of the roll within the tube is held stationary by the ratchet and pawl, with the free end of the strip in the slot I8, so that a further portion of the paper may be dispensed as and when desired. W

When all of the paper strip la of the roll, between the lines 2, has been dispensed, the roll appears as in Figure 6. The central portion of the core 6 is visible, with the two opposite end portions lb and I c or the roll beyond the score lines still in place on the core. The advantage of this is that these two opposite end portions serve to guide the roll while all of the paper is dispensed therefrom, for the lower end portion lb maintains a full. hearing with the in erior of the tube while the upper end portion lc maintains a full size tight contact with the socket H]. To apply a new and unused roll, the finger piece II is simply withdrawn, carrying with it the remainder of the paper roll shown in Figure 6 and this used roll is removed from the socket l0 and a new one inserted in its place and re-assembled on the pencil.

I wish to lay particular stress upon the convergence of the line of weakness 3'. This feature is of great importance to the present invention for it allows the paper to tear cleanly from the roll and experience has demonstrated beyond question that this cannot be accomplished if the score lines 2 were parallel. By the converging arrangement shown, the paper is free to tear cleanly along the scored lines and does not have to tear in contact with or over edges previously torn. The paper will thus remain tight on the roll and the strip la will readil be severed along the lines of weakness and projected through the slot in the tube, leaving the tab end of such strip in juxtaposition with the slot in the tube and in a position to be projected therethrough by the next dispensing operation. If parallel lines of scoring were used, it has been conclusively demonstrated that the dispensing force projecting paper through the slot will break the parallel scoring of the paper roll within the slot for a considerable portion of the web of the roll, causing a considerable length of loose paper to remain within the tube, thereby making it practically impossible to dispense any additional paper through the slot of the tube.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.

The part 9 shown in the accompanyin draw-- ings'has been specifically referred to as a pencil. It may be of the usual type embodying a sliver of graphite or may be of the magazine type, or, if

desired, it may be a pen of conventional or ball point type, without departing from this invention.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is: p I

1. As a new article of manufacture, a web of paper having converging lines of weakness extending longitudinally thereof in spaced relation from the lateral edges of the web and from each other, said web of paper being rolled into a compact roll with the lines of weakness at their maximum spacing at the outer terminus of the web.

2. As a new article of manufacture, a web of paper having converging lines of weakness extending longitudinally thereof in spaced relation from the lateral edges of the web and from each other, said web of paper being rolled into a compact roll with the lines of weakness at their maximum spacing at the outer terminus of the Web, and adhesive applied to the successive convoluticns of the paper at the opposite ends of the roll to maintain those portions of the web between the lines of weakness and said opposite ends of the roll in permanently rolled condition while permitting severance along the lines of weakness of 6 a the intermediate portion of said web which lies between said lines of weakness.

3. As a new article of manufacture, a web of paper having converging lines of weakness extending longitudinally thereof in spaced relation from the lateral edges of the web and from each other, said web of paper being rolled into a compact roll with the lines of weakness at their maximum spacing at the outer terminus of the web, and an adhesive applied to the opposite ends of the roll and spaced from said lines of weakness.
