IMPROVEMENT IN ROLLING OR WINDING PAPER IN THE MANUIA GIURE OE PAPER GOP-TUBES.

Be it known that I, SILVANUS DURGESS, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Rolling or Winding Paper in the Manufacture of Paper Cop- Tubes for spinning machines, and of paper cartridges and similar articles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being:r had to the accompanyinfjr drawings,

'making part of this specification, in which are represented a longitudinal elevation and section of the essential parts of a machine for making paper cop-tubes, to which my improvement is added.

In the said drawings, D D are a pair of delivery or feed rolls between which the strip of paper'k(represente.l by the red line) passes, and thence through the trough or guide E to thc spindle m, upon which it is rolled or Wound to form a cop-tubo, the. One side of the strip of paper is covered with paste, so that as the successive wrappings of paper are wound upon the spindle m they become firmly united, and form a seamless quill or tube of paper suitable for the above purpose. In some instances the strip of paper used is of the same width as the single tube is required to be in length, and in others the width of paper is such as will form a long tube, which is afterwards divided up into the lengths required. In either instance, however, my said improvement is applicable and available for removing a difficulty which I will mention. When the pasted side of the paper strip is presented to the revolving spindle m to be wound thereon, it often happens that the strip is simply curled, andA passes directly over the spindle instead of being wound thereon, or, -if it should be wound thereon, some of the folds or wraps would be wound more loosely than others, or wound so loosely one upon another as to interfere with or prevent the formation of a tube, and so frequently does this occur that the operation of making tubes by such means has been found to be impracticable. This result is attributable to a number of causes. The size of the spindle and its rapid revolution render it difficult for the end of the paper to catch upon it or instantly adhere to it so as to be wound up, even when the paper has been specially manufactured for this purpose, and the paste used is of the most tenacious kind that could be worked in such operation. The principal cause, however, is, that the application of the moisture of the-paste to the under side ofthe paper so fulls and expands the material on this side as to make the strip bend and curl in the direction of its dryer surface or side, and in the opposite direction from that in which it is to be wound, in consequence of which the pasted paper naturally avoids and resists the winding action of the spindle', not only upon corningin contact with its revolving surface, but after one or more wraps or coils have been wound thereon, and the result is as above stated.

New, my improvement for overcoming this difficulty consists in moistening the opposite side of the paper from that to which the paste has been applied in its passage to the spindle with water, applied in any suitable manner that will meisten the surface evenly, so that, as the water the more readily penetrates the paper than the moisture ofthe paste, not only is thel elasticity of the paper destroyed, but the paper is made to incline or curl towards the pasted side, and thus to catch and adhere to the spindle and to be compactly wound thereon` and form a perfect quill or tube in every instance. i The water may be applied to meisten the paper in a number of ways. One way which I have essayed with success is shown in the accompanying drawings. A sponge, S, is confined in the trough E, or in such a manner that the paper may pass freely beneath. but in contact with it, while the moisture which is taken up by the passing paper is'supplicd from a dripper or vessel, B, over the sponge, provided with a suitable cock cr spigot to regulate the escape of the water therefrom.

By the application of moisture in the manner described, I am enabled to use the ordinary and cheaper quality of paper, and make at each and every successive operation a perfect tube of a superior quality, and to make them witlrgreat rapidity. I am also enabled to roll or wind into the form of a cylinder of any desired diameterthe thicker and coarser kinds of paper, for the manufacture of paper boxes of different kinds, and for ,other useful purposes.

Having described my invention, what I plaim, and desire to secure by Letters Patent, is Moistening the paper to be rolled up or wound, substantially as and for the purpose set forth.
