- TOILET-PAPER.

SPECIFICATION forming part Of Letters Patent NO. 440,828, dated November 18, 1896.

Application filed February 19, 1890. Serial No. 341,053. (No specimens.)

.To all whom it may concern:

Be itknown that I, EDGAR JEROME, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Toilet-Paper; and I dohereby declare that the following is a full,

clear, and exact description of the same.

My invention relates to rolls of paper made up of astrip or web separable into sheets and designed for toilet and wrapping purposes. Itis of that class in which the web is partially severed to facilitate the separation of the sheets as they are drawn from the roll.

My invention is more particularly applicable to the form of paper shown in an application filed by me in the United States Patent Office on the 28th day of May, 1889, Serial No. 312,388; but it is also applicable to a paper Web otherwise partially severed from the margins. I

My invention is shown in the accompanying drawings, in which- Figure 1 represents the sheet or roll in plan, and Fig. 2 represents the same with the sheet partially drawn from the roll.

In the drawings, A represents the roll of paper made up of aweb or strip aof any suitable kind and width. The web dis shown as partially drawn out. It is a plain web and formed with straight parallel edges. The web is subdivided partially by severing it from the margins toward but not quite to the center. This is done either by cutting or tearing, preferably the latter, as shown by the lines I) c b c. The lines of severance between any two sheets are made opposite each other, and it is sufficient to leave about one-fourth of the web unsevered. The unsevered part is sufficient to hold the sheets together in rolling and unrolling; but as the cut or rupture of the paper extends into the web from each side the slightest swaying of the web after it is drawn out either to one side or the other extends the cut or ruptureand thus severs the paper.

The invention so far described is the same as that shown in my aforesaid application.

It is well understood by those skilled in the art that it is desirable to have the pieces or sheets of the roll of paper of this class separable from the web with the greatest possible facility, so that each piece may be severed by pulling without unrolling the web to too great an extent. At the same time considerable strength is required in the uncut or unruptured part of the roll which connects one sheet with another, in order that the web may be wound into the form of a roll in the process of manufacture. It will also be understood that the grain of the paper or its fiber runs lengthwise of the web or at right angles to the desired line of rupture. Therefore the marginal cuts or ruptures when the sheet is pulled tend to turn from a direct line across the web into a line parallel with the web, so that the tendency is to pull off a part of the sheet instead of a whole sheet. The object, therefore, of my present invention is to correct this tendency and to facilitate the transverse rupture without weakening the bond between the sheets, so as to interfere with the process of winding the web into a roll. It is necessary to leave an unruptured part in the middle at about one-fourth of the whole width for the purpose of winding, as above explained. In order to facilitate the transverse rupture, 1 provide a diagonal cut or cuts in this unruptured part, extending equally 0r substantially equally into each sheet and inclined slightly from the longitudinal line or axis of the web. If more than one inclined out is made, the cuts are arranged parallel with each other. As they are inclined, they cut the longitudinal fibers of the web, so that the unsevered portion may tear from out to out along the weakest linesthat is to say, on the longitudinal lines. At the same time this rupt ure takes place when the pull is not direct; but when the pull is direct substantially the ordinary strength of the paper remains, and as the pull is direct in winding in a roll the winding is accomplished without difliculty. When a sheet is to be torn from the web, the user ordinarily pulls a little aside, and this continues the lateral rupture, which runs easily into one of the slits. The rupture continues from the first slit partially lengthwise into the second, and so on across to the opposite rupture.

I am aware that in rolls of toilet-paper the web has been partially severed by lines of short inclined cuts from one side to the other of the web, alternate cuts being inclined in opposite directions, this being an equivalent for the weakening by punching holes. The object which I have in view is not gained by this, as the weakening in this case is also a Weakening in respect to the longitudinal pull of winding as well as to thelateral pull given in severing the sheets.

It will be observed in my construction that the inclination of the cuts is not such as to sever all the longitudinal fibers, which would interfere with the winding of the roll, and it is a necessary limitation of my invention that it be in the form shown, in which the inclined cuts do not sever all the longitudinal fibers in the paper of the tongue or bond connecting the sheets and between the lateral ruptures, but leave some of these fibers'entire' I claim as my invention A toilet-paper roll formed of aweb severed EDGAR JEROME.
