To ail whom itmay concern.-

Be it known that I, FLINT W. WRIGHT, a

verse sectional View on a larger scale of a portionof the wrapper. Fig.v 3 represents a transverse sectional view of the completed wrapper after it has been rolledup a nd Fig. 4 represents a transverse sectional view of a strip of cardboard before it is .inolosed in its papercover. I 1

Similar letters refer to like parts in the different figures.

Referring to the accompanying drawings, A denotes a sheet of firm paper one-half of which is represented as extended at A. One end of the sheet is square and the'opposite end is preferably pointed or triangular, as at A and the tip of the pointed end can be provided with a gummed section,- as at A Upon the central portion of thepaper sheet A when it is extended is placed a sheet B of firm cardboard, which is prepared by slitting the cardboard except at its ends, where it is. left united as represented at, B, Fig. 1, one end of the cardboard-sheet being shown in said Fig. 1, the end not shown being a duplicate of the end disclosed. The cardboard is preferably cut entirely through, forming slits B nearly the entire length of thecardboard, but left entire at each of its ends, as. at B, so the separate strips of the cardboard at B are held parallel with each other and at a uniform distance apart. The cardboard is also skived at its opposite edges, as at cane C, forming beveled edges, preferably upon' op posite sides of the cardboard. A coat/6f glue or paste is applied to the opposite sides of the cardboard, which is placedhi'pon the -sheet of paper in the position shown in Fig.1, and the square end of the sheet is then folded over and upon the glued piece of cardboard, as represented inthe left-hand half of Fig. 1, thereby inclosing the cardboard and adhering firmly to both sides thereof.

The slits I5 are out just wide enough so that when the wrapper is'rolled into a circular form, as shown in Fig. 3, the edges D of the strips 13 will come into contact with each other or with the folds E of the paper cover,

causing the edges D to crowd against each other and'form a mutual support, so as to resist outside pressure and form a tube in which matter can be rolled for transmission through the mails with safety.

By reference to the sectional view shown in Fig. 3, it will be observed that the contact of the strips B is at the inner corners, while the outer fold of the paper cover serves to hold the strips together. The skived edges 0 and Cfifold together and prevent toogreat thickness at the folded edges.

By leaving the cardboard united at its ends, as at B, the strip of cardboard can be placed in position and folded into the paper cover without any regard to the distance between the strips B as these strips are held in place parallel with each other and at the required distance'apart, by the united ends B.

In the above-described wrapper it is necessary that the strips of cardboard possess sufficiently firm and unyielding edges and that the strips be arranged upon the sheet of paper at substantially a uniform distance apart and with the proper space between the-strips, so the inner corners of the contiguous strips will crowd against each other when the wrapper is rolled, thereby forming atnbe which is capable of resisting outside pressure tending to collapse the tube or reduce its diameter, each of the strips, when the wrapper has been rolled into the form of a tube, forming a portion of acontiuuous arch capable in itself of resisting pressure.

What I claim as my invention, and desire to secure by Letters Patent, is

1. As an article of manufacture the within described mailing wrapper'comprising the ends, whereby the edges of said slits are main tained parallel and at a 'uniferm distance apart, as and for the purpose specified; 'f

2. ,As an article of manufacture, a mailing Wrapper musisting of a cover A anda piece of cardboard B attachedto said cover, said cardboard having a series of slits 17 which the cardboard is divided into paralle strips, said strips being left united throu h a p01" lion-pf their length, whereby said 8 tips are Dated this 20th day of October, 1189;.
