TO ALL WHOM IT MAY GONCERN: l

Be it known that I, GEORGE W. CHIPAIAmof Bostenfin the county of Suifolk, and State of Massachusetts, have invented an Improvement in Carpet-Lining; and I do' herebyl declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suicient to enable those skilled in the nrt to practise it.

UnitedStates Letters Patent, No. 14,585, granted to J. It. Harrington, and now owned by me, relate to the mannfacture of a-carpet-lining, consistingr of acontnuous sheet or layer of softloose, iihrous material, surfaced by a sheet or sheets of stout paper, the batting being kept in place, relatively to thesurface of the paper, by cement or otherwise. Y

The moans for so uniting the paper and wedding-have been to cement 'the entire inncusurface. of the paper to the wadding, to press the sheets together, to cement together the adjacent edges of' the paper sheets, or to stitch the sheets together, each of these means beingpraeticnble, though there are some objections to the use 4lofV either.

rIn my present invention I use cementltious matter to confine the sheets together, but instead of's'preading it over the whole surface of'the paper, I apply it in spots, or in parallel 1ines, whereby I retainthe general 4elasticity of the wadding, or prevent the paper and wadding from matting together, as they incline to do in covering the paper with cement, and counteract the tendency of the paper to tear at the lines`ot` connection,

as'it inclines te do in sewed-lini'n'gs.

My invention consists in a carpet-lining, in which the sheets of paper and of soft iibrous lling are secured together, or from relative lateral displacement, by spots or lines of cement, distributed over the surfaces in contact, at such intervals of space as shall permit the liningto preserve the general fulness or elasticity desirable .ina carpet-lining.

The -drawing represents apiece-of carpet-lining embodying my improvement.

a and b denote the two sheetsot paper; e, the sott-wedding or batting enclosed between them.

d d denote spots of cement, or spots opposite to which the cement is applied, 'the cement being dropped pr applied, by'a suitable brush, to tbe'inner surface of the paper, at regular intervals, by mechanism connected with and forming part of the linii'ig-'makii'ig machine, the cement being applied to each sheet ofpaper just before the paper and wedding come intocont'aet. i

v Instead of using drops or spots of' cement in this manner, thc cement maybe applied in short lines, as shown at e, or in continuous lines, as shown at f. v Y

I claim a carpet-lining, the wadding and paper sheets ofwhich are confined together by the lines or spots of cement, substantially as setforth.
