IMPROVEMENT IN'GARPET-WAIDING.

@Le .Signale narra tu iii tlgeseetter patent ma machtig *met iii-'tige time.

TO ALL WHOM IT MAY CONCERN Be it kno .vn that I, THOMAS H. DUNHA'M, of Boston, in the county of Suiolk, and State of Massachusetts, have invented a new and useful Improvement in Carpet-Wadding, the samebeing a new article of manufacture; and I do hereby declare that the following is a full and exact description of the same, and of one mode or pro'- cess that may be employed in its manufacture, reference being had to the accompanying drawing, and to the letters and figures marked thereon. A Y

Figure I is a plan or top View of a piece of the carpet-wedding.

Figure II is a vertical section of the same.

I-will rst refer to Letters Patent of the United States granted to nie on the iirst day of May, A. D. 1866, and numbered 574,312, for an improvement in carpetwadding, the same being anew article of manufacture, produced byrun'itinga'gl bat o'r layer of cotton, or other fibre, to paper, by causing it to he delivered or laid upon the newly-formed web or continuous sheet ofpaper .which has justv been formed from the pulp in a paper machine. In the article thus made the fibrous material adheres tothe paper without the use of gums or any adhesive substances.

i The new article that I have produced is the saine as that above referred to, sofar as relates to the adhesion or attachment of the batting or sheet of bre to tlhepaper, the improvement in the same having reference -exclusively to the selvedge, margin, or border whichv forms the outer edges of the sheet of finished wadding, two or more sheets of paper being closed together while in the moist condition above referred to, thus ,enclosing the sheet of fibre in aV at bag or sack, and preventing the exposure of the 'edge ofthe but, the escape of dust, and the entrance of moths and other insects.

vIn the gures, the direction of the length is represented by the arrows, and the breadth of the wadding is shown between A and B. The hat or fibre L is narrower than the paper., occupying the space from G to G. Outside of this, to the right and'left, are the two selvedgcs, or borders- Il and J, formed by compressing 'or closing the edges of the sheets of paper together. This may be done by'neans of narrowrrcllers or other suitable mechanism while the paper is still moist, and before it becomes hard `by exposure to the air or by drying with artificial heat. In seme cases I prefer to make the selvedge or border in corrugated form, as represented at H, thus causing the contact of a larger surface of paper and firmer adhesion of 'the sheets. Either the plain or corrugated edge or border may be used, as preferred, while the main features of theinvention are retained, vi'z, the enclosure of a sheet of batting or soft fibrous substance between sheets of paper united at the outer edges or selvedge while the paper is in a moist condition, as above stated. By the use ofvvery strong and thin paper and a bat or sheet ofwool, hair, or other animal fibre, I prepare a thin and light kind of wedding suitable for use in clothing that requires to be stuffed or padded. 'It is not liable to slide upon the paper, and when packed or'stored in bales in readiness for sale or use, it remu'n'sxin goed order for :my length of time, as no moths can obtain access to the enclosed bre.

What I claim, and desire to secure by Letters Patent, is-

A wedding or fabric, having an adherent border or selvedge formed of the sheets of paper that project beyond the edges of the batting, and attached to each other, as herein specified, without the use of gum orother adhesive substance,substantially as described.
