PAPER SHEET AND METHOD OF MAKING THE SAME.

Application filed December 10, 1920, Serial No. 429,698.

To all whom it may concern:

Be it known that I, WALTER D. ED oNDs, a citizen'of the United States, and a resldent of the township of Boonville, in the county of Oneida and State of New York, have invented a certain new and useful Improve-- ment in Paper Sheets and Methods of Making the Same, of which the following 1s a specification.

My invention relates particularly tothose well-known sheets of paper, containing a plurality of thereon inscribed similar units such as blank bank checks, stock certificates, postage'fstamps, etc. and composed usually of fibrous material, portions of which have been cut out therefrom to form a plurality of alike mutually proximate circular per,- forations, disposed usually in a line, or row, dividing said units and along which the sheet is usually severab-le by merely pulling it apart, thereby detaching one or more of said units from the remainder, and the objects of my invention comprise impartation to such sheets of more easy, certain and accurate division, or severability, along their said lines, or rows, of perforations, this being of late years increasingly needed owing to the comparatively inferior paper and fibrous materials necessarily employed owing to scarcity of better stock, the result being that the old time perforations prove too often inadequate to control the line of severance, or tear the paper owing to its comparative lack of required homogeneityand cohesiveness, giving way or parting in directions angular to said rows.

In the accompanying draWings- Figure 1; is a diagrammatic plan, or top, view of a sheet, or page, of a check book from" which the uppermost check has been re-- Figure 5 is a view similar to Figure 4 experforations, p,

'forating cept that the crease is madefrom the under, instead of the upper, side of the sheet.

I attain my objective as follows I, preferably cut out of and remove from the sheet of paper, 8, by any of the well-known, heretofore employed, procedures, portions thereof thereby making the familiar plurality of p, p, on any given, usually a stralght, line between the units above referred to; and, in addition to this, either simultaneously, or by a separate operation: I mpart to the sheet, including, particularly, lts component fibrous materials in exactly said line, and consequently wherever extending between saidperforations, less strength. 1. e. less resistance to tear, than heretoforecare being, of course, taken to thus not so greatly impair normal coherence as to induce breakage prior to intentional separation. This required, strictly local, comparative weakness of the material where left between the perforations I impart thereto by procedures so well known that no particular description thereof is, I believe, required in order to understand and practice my invention. My line, or zone of novel relative weakness between the perforations is preferably produced by simply creasing and thus compressing the material on a line coinciding with the mesne median line of the perforations. This crease, indicated by c in the drawings, can, as will be apparent to those skilled in the art, be imparted by suitably connecting the old perforating or cutting out lnstrumentalities with any usual creasing device, for example a blade, or plurality of blades, not show n in the drawings, but so disposed, supported and adjusted that the pressure applied to actuate the usual perdevices will serve simultaneously to impress the creasers, or blades, sufficient-ly into the sheet to indent or compress, it between the perforations and to the required extent; or, of course, the perforations may be made in one operation, and thereafter the creases in another.

The result is that thenormal elsewhere thickness of the sheet is reduced between the perforations as plainly indicated in Figures 3, 4 and 5, and what is more important for my purpose its constituent intervening weakened by being fibrous material is .crushed, twisted or bent to such degree that it is there tearable, or

breakable, much more readily than wherever elsewhere the sheet is ered, therefrom with substantially complete avoidance of the present above referred to too great risk of tearing into, or injuring, adjoining units.

It will be understood that my perforationconnecting creases, 0, c, are preferably impressed from the face, 7, or printed side, of the sheet, as indicated in Figures 3 and 4, but they may be usefully indented from the reverse, side, :2", (Figure 5) or from both sides.

My invention not only facilitates and safe-; guards the tearing apart of the sheet as above described, but is also particularly useful in that it dispenses, if desired, with many of the perforations formerly required alonga given line, in other words by aid of my crease, the sheet is readily severable,

though the perforations be much more widespaced apart than heretofore.

A notable and important feature of my invention is also its location of one of the perforations, for example 12 (Figures land 2) concentrically with the point at which two of my crease lines extending angularly to each other would intersect if thereto projected, this disposition greatly contributing to safe turning of the line of tear in the required direction.

I am aware that it has been suggested to merely fold a sheet of paper and provide it with a series of perforations along the fold in order to readily separate an opaque from a transparent portion of said sheet,the said folding thereof being for the purpose of superdisposing said two portions of the sheet in order" to insert and impress them simultaneously in a typewriter. claim as my invention, it being distinguishable not only because failing to compress, i. e. crease, indent, or otherwise reduce the thickness of the sheet between the perforations, but alsobecause such mere folding on the line of perforations is more or less deleterious, and altogether impracticable, for my purposes when the sheet contains two intersectant lines of perforations as is usually required.

This I do not Having now described my invention, what I claim as new and desire to secure by Letters Patent is the following, viz

1. -A paper sheet containing'a row of perforations, the thickness of the sheet being between said perforations, and throughout the median line of said row, less than in other parts of said sheet.

2. A paper sheet contalni ng arow of perforations the constituent material being compressed throughout the median line of said row. v

3. A sheet containing a row of perforations and a line of continuous compression or indentation extending from one perforavtion to the next, nearest thereto perforation.

4. A paper sheet containing a plurality of perforations disposed in one row, and another plurality of perforations disposed in another row, the said rows being mutually intersectant and the paper between said perforations being alongsaid lines continuously compressed from one into the other of mutually adjacent pairs of said perforations.

A paper sheet containing a plurality of perforations disposed in one line, and another plurality of "perforations disposed in another line, the said rows being mutually intersectant, one of said perforations being concentric with the point at which said lines,

or rows, would, when thereto projected, in-;

tersect and the paper between said perforations being along said lines continuously compressed from one into the other of mutually adjacent pairs of said perforations.

I 6. The method of treating a sheet of paper 'which comprises making therein a plurality of perforations along-a given line and also compressing the paper between said perforations. ,I

7,. The method of treating a sheet of paper which comprises making therein. a plurality of perforations disposed in one line, and-ark other plurality. of perforations disposed in another line,'the said rows being mutually intersectant, and then diminishing the tl fickness of the paperbetween the mutually adjacent perforations.

8. A paper sheet comprising a plurality of therethrough spaced-apart openings from the edges of which, in the plane of the sheet, portions of the paper have been completely severed and removed, the remaining portions of the paper extending between said openings are of less coherence than the remainder of the sheet.
