PAPER-ROLL.

Specification of Letters Patent.

Patented Feb. a, rare.

Application filed January 14, 1915. Serial No. 2,203.

To all whom it may concern:

Be it known that I, SETH WHEELER, a citizen of the United States of America, and a resident of Castleton, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Paper-Rolls, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to rolls of paper for toilet, towel, napkin or similar purposes and has special reference to such as have a series of incisions in a single plane.

One object of my invention is to provide a simple roll or package of paper towels, napkins or toilet paper that may be manufactured at small cost, that shall be adapted to be supported by a particularly simple form of holder and at the same time, shall be composed of sheets of substantially uniform size.

Other objects and advantages of my invention will be set forth hereinafter and in order that my invention may be thoroughly understood I will now describe the same in the following specification and then point out the novel features thereof in appended claims.

When rolls of paper as ordinarily formed are provided with a series of through cuts or incisions, all in substantially one plane for the purpose of permitting the roll to be suspended on a simple hanger, so that it may be easily separated into sheets; the sheets have necessarily been of varying length by reason of the continuously increasing diameter of the roll from the inside out. This necessitated the innermost sheet which was the smallest, being made of adequate length and all of the others being wasteful of paper to the extent that they were larger than necessary. This difliculty is particularly prominent in the manufacture of rolls for paper towels, and if the first sheet is made of adequate length, the one-hundredth sheet, with paper of the usual thickness, will be twice the size of the first. This difficulty is overcomeby the use of my invention. 7

Referring to the drawings :Figure 1 is a partial sectional elevation of a paper roll constructed in accordance with my invention. An end view of the same is shown in Fig. 2. A partial plan view of the roll without its holder is shown in Fig. 3. Fig. 4 is an end view of a flattened roll which also embodies my invention.

Having special reference to Figs. 1, 2 and 3, the roll here shown is wound on a core 10 which has the general form of a cylinder provided with an inwardly extending longitudinal channel or groove 11. The core may be formed of cardboard or the like with its outer circumference substantially equal to the length of a single sheet of paper of whlch the roll is to be composed. The channel 11 is tapering in cross section as shown in Fig. 2, so that the paper may be readily wound onto the core in such a manner as to follow the contour of the same as clearly indicated in this figure. When the roll is complete as shown, a plurality of incisions 12 are cut in a single plane and a slmple hanger, such as the hanger 13, is lnserted with a tongue extending outwardly through one of the incisions 12.

The holder forms no part of my present invention and any suitable holder may be employed, in fact a wire or cord may be looped through one or more of the incisions and serve as a holder. A pair of spaced holders may be used instead of one, if desired.

The groove or slot 11 is gradually filled as the successive convolutions of the paper are wound on the core and consequently the convolutions gradually approach a cylindrical form which the last convolution completes. Thus the otherwise increasing diameter of the roll is compensated for and the convolutions are substantially equal in length and area. Since the incisions are cut through the roll in a radial plane, the sheets of paper, which may be readily separated at the perforations formed by the incisions, are of substantially equal size.

It is not essential that the core shall have a substantially cylindrical form, and as shown in Fig. 4, my invention is equally applicable to a flattened roll. The roll as an article of manufacture may or may not comprise a core such as the core 10 of Figs. 1 and 2 and my invention is not restricted to either arrangement.

It is evident that other modifications may be efiected within the spirit and scope of my invention, and I intend that only such limitations be imposed as are indicated in the appended claims.

convolutions of substantially equal length,

the excess material in its inner convolutions being assembled at a single point of theperiphery of the roll, and said roll being provided with a line of perforations in the 1 same plane extending transversely across and through the convolutions from the interior to the exterior of the roll.

3. A paper roll comprising a plurality of turns wound in the form of a flattened spiral, each of said turns being folded in- "'wardly at one edge of the flattened spiral,

and radial cuts or incisions through the roll at the opposite edge, of the spiral, said folds being of gradually decreasing depth from the innermost turn outward to com-- pensate for the thickness of the paper,

whereby the turns are of uniform size and maiy be removed from the roll sheetby sheet. 11 testimony whereof I have hereunto set my hand this 12th day of Jan. 1915, in the presence oftwo subscribing witnesses.
