T all whoma may concern:
county of Alameda and State of California,
have invented new and useful Improvements inlnterleaved Paper Articles, ofwhich the following is a specification This invention relates to inter-lea-ved' sheets, andpertains especially to paper towels, toilet paper and the like.
The primary object of the invention is to so fold andinter-leaf paper sheets, whereby such sheets,even when made of the flimsiest and softest quality of paper, when grasped by a wet hand, will not be torn when drawn from the holder,
In the demand for things sanitary, a large market has developed for individual paper towels and the problem has been first, to arrange the towels so that they may be withdrawn singly, and second, to insure against their being torn by the wet hands.
The invention consists of the parts and the combination and construction of parts as hereinafter more fully .described and claimed, having reference to the accompanying drawings,'1n which Fi ure 1 is a vertical, longitudinal section illustrating the folded towels. Fig. 2
is a plan view of a towel unfolded. Fig. 3
is a detail perspective showing folded towels. A represents a paper towel according'to our invention; each individual towel con- 85 sisting of a single sheet of paper of suitable absorptive material.
The construction of the towels, as well as the method of arrangement for dispensing the towels, are the featuresof the present invention.
Each sheet A is folded adjacent to its center, as shown at 2, so thatthe-sheet-is divided into two portions of unequal length 3 and 4.- Thelonger section 3 being the section of eater area is -folded in an opposite direction to the section 4 along the transverse line 5, near its outer end, so as to provide a short end edge fold 6. The length of this short folded section 6 is such that its edge 7, which is exposed, is approximately coincident with the edge 8 of the under folded section 4; in other words, the length of the narrowfolded portion 6, measured on the line of the length of the folded sheet,
plus the length the under folded. section 4, approximately equals the length of that 1 portion ofithetop section 3 between thelines 2 -5. When a sheet has thus been folded the three sections are in relative ;zig-zag formation; that is, the'section fizand sectionf4. are folded in opposite. directions on section 3. I
Assuming. that each; leaf- A1 is foldedsin the manner described, then each sheet is interlocked with".tli e next adjacentisheet' so that all of the sheets are, connected by each bemg folded alternatelyoo'ver-or with a half of the succeeding sheet; 7 In actual practice this interleayingjis done by machinery, not
n essary here. to be. shown but formin the subject-matter of. a separate applicatmn,
whereby the leaves are 'turnedifrom two continuous rolls. of and interfolded 1n the, manner before described; the doublefolded section 3- of one sheet being adjacent to the'section 4 of an immediately succeeding sheet, so that the edge 8 of the, latter sheet is really a'con- 'tilnuation of the edge 7 of the next adjacent s eet.
One important Ieature of this invention is the fact that these individual sheets A are made from a, practically continuous web, which web in its manufacture has its grain of greatest strength running lengthwise of the web. That is, in our paper towel the grain islengthwise of the towel and the folds 25 are both crosswise of the grain, thus making a much stronger paper towel than would be made by having the folds run lengthwise of the grain. When the sheets are so folded and interleaved they are placed in a container, as B, which container has a. slot C through which a section 3 of the outermost sheet may project with 'the narrow fold 6 exposed to view. When a person desires 'a' sheet, the folded port1on6 is grasped by the fingers and a sheet'pulled out. The actof pulling out one sheet ex-' poses the next succeeding sheet with its fold 6 in readiness for the next operation.-
As the hands of the user are usuall wet,
paper and 'cut alternately /it has been found that, with towels oldedg further reinforced the towel by overturning -a short finger-hold section, as 6, with the ning lengthwise of the sheet and. have terial are to be dispensed.
Having thus described our invention, what we claim and desire to secure by Letters Patent is 1. A stack of leaves for use in a slotted container consisting of a series of sheets, each sheet being folded into an under long part and a top short part, the free end of the long part being folded over to form a relatively narrow hand gripping fiap of double thickness, said sheets being arranged so that the flaps of the sheets are-engaged L between and directly with the under and top parts of an adjacent sheet and at the central line of fold of the sheet whereby ,when a lower sheet is pulled out of the con- .tainer slot same will draw the hand grip-- ping flap of thenext sheet through the slot and then will disengage itself from said adjacent sheet without completely pulling the latter through the slot.
2. A paper stack consisting of a series of U-shaped'leaves one of the free ends of each are alternately located at opposite ends of the stack and are received in the space between and directly engaged with the parts of said adjacent leaves. 7
3. A paper stack consisting of a series of leaves having a lower long part provided with a hand gripping folded over flap and a short upper part, said leaves being arranged so that the short upper part and the flap of two adjacent leaves extend in the same plane and at their free edges confront one another and are received between the upper and lower parts of a third leaf.
In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
