EDWARD B. ALLEN, or BRIDGEPORT, CONNECTICUT, AssIGNoR' TO THE srNGER MANU- FACTURING COMPANY, A CORPORATION OF NEW JERSE' TAPED SEAM FOR SEWED ARTICLES.

Specification of Letters Patent.

Patented June 25, 1912.

Application filed July 8, 1911. Serial No. 637,407. v

Be it known that-l, EDWARD B. A LEN, a citizen of the United States, residlng at .Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Ta ed Seams for Sewed Articles, of which the ollowing is a specification, reference being had therein to the accompanyingdrawings.

This invention relates to a means of uniting the abutting edges of heavy woven materials such as carpets, and particularly for such articles as rugs wherein breadths' of material are abutted and united by a blindstitch seam; and it has for its object to protect the edges of the fabric from fraying out when the article is cleaned by heating orotherwise or when repeatedly rolled and unrolled for display to customers in retail stores. I

The invention consists essentially intwo body fabrics having theiredges abutted and covered by a stretched elastic tape and united by a line of stitching entering and emerging from the same side of the tape and disposed transversely of the abutting edges of the body fabrics.

In order to insure against theexposure 1 of the stitching upon the-face of the fabric,

it has been common heretofore to arch the marginal portions of the fabric with their backs exposed to the stitch forming mechastretching the same both edgewise and fabrics in their arche nism in such manner that a stitching thread was caused to-enter and emerge from the convex face or back of the fabrics on opposite sides of their junction; a mechanism suitable for such operation forming the subject of my United States Patent No. 524 996, of August 28, 1904. Were the ordinary inelastic tape merely laid over the abutted edges and stitched down by the same uniting stitches, the flattening out of the article would produce a crimp .or fold in theprotecting tape along the seam and would thus form an objectionable ridgeupon the under face; but by employing an elastic tape and len thWise pre arator to appl ing the fasteni n stitched, the ullness provided for covering the marginal ortions of the two relation for the stitching operation is taken in, when the article is flattened out, by the elasticity of the tape which latter is thus ermitted to lie flat without puckering or wrinkling.

The invention will be understood by reference to the accompafiying drawing, in which Figure/1 is a perspective view of the two body fabrics with their adjacent marginal portions arched and their edges abutted with the overlying stretched elastic tape secured thereto by the uniting line of stitching; and Fig. 2 is a perspective View of the same parts with the fabric flattened out subsequent to" stitching, and representing in full lines the contracted width of the'covering tape and in dot-ted lines the ,width of the latter as it is stretched for the stitching opera-' tion.

The carpet sections '1 and 2 are each formed with an inelastic woven back 1 and 2*, respectively, and with a face composed of the piles 1 and 2 the backs being shown uppermost in the drawings. The marginal portions of the carpet sections are arched and their adjacent edges are abutted at 3; as shown in Fig. 1, and over the abut-ted edges is applied the elastic knitted strip or tape 4 which is in practice stretched both endwise and sidewise to cover a considerably greater area than it naturally occupies. The line of fastening stitches is shown applied with loops of one thread 5 passed through one of the margins of'the tape 4 and thence successively through the carpet sections 1 and 2 and across the abutted edges of the latter,'and*through the other margin of the covering tape from which it emerges upon the same face that it entered at the other side of the joint of the carpet sections, the loops of needle-thread being shown interlooped wit-h loops of looper-thread 6.

. As will be observed by reference to Fig. 2, l

ing and permits the same to shrink from the width represented in dotted lines at 4 to that represented in full lines at 4 in said figure, the tape still remaining taut in its flattened condition, and therefore increasing the thickness of the carpet or rug at the joint merely-by its own thickness, which is comparatively little.

While 'any suitable means may .be provided for applying the tape, I prefer to employ, in conjunction with the carpet sewing machine before referred to, a binding guide similar in general form to that represented in my Patent No. 600,502, of March 15,1898,

but provided with a tension device for producing a drag upon the tape as it is drawn through the binder, with means such as is shown in my Patent No. 600,503 of the same date for stretching the tape edgewise at both sides of the center. It is found desirable in practice to stretch the tape lengthwise as well as sidewise, as the latter alone, if effected progressively and correspondingly with the progress of the stitching, tends to draw in or shorten the tape lengthwise so as to produce a slight fullness when the article is flattened out subsequent to stitching.

While the abutted edges of the body fabrics may in some cases be covered by an overseam to prevent raveling occasioned by the repeated handling of a rug or other article composed of united breadths of fabric, a knitted tape is less expensive and more effective as a protection for the edges of the fabric, especially as a high grade of Irish fiax thread is at present required by the trade for stitching together the component breadths or sections of a carpet or rug.

It is evident that the exact texture of the fabrics employed and the character of the stitching used to unite them are not essential to the present invention, which is sus- V name to this specification, in the presence of ceptible of modification in certain respects from the embodiment shown and described herein.

Having-thus set forth the. nature of the invention, what I claim herein is 1. A seam for sewed articles comprising two body fabrics with abutted edges, an elastic tape overlying said abutted edges, and a uniting line of stitching passing through said body fabrics and across their abutted edges and through the opposite margins of the tape.

2. A seam for sewed articles comprising two inelastic body fabrics with abutted edges, an elastic tape overlying-said abutted edges, and a uniting line of stitching passing through said body fabrics and across their abutted edges and through the oppo: site margins of the tape.

3. A seam for sewed articles comprising two -body fabrics with abutted edges, an elastic tape overlying said abutted edges, and a uniting line ofstitching passing once through each of said body fabrics and twice through said tape.

.41. A seam for sewed articles comprising two body fabrics with abutted edges, :1.

stretched elastic tape overlying said abutted edges, and a line of stitching for uniting together said abutted edges and the overlying tape, said stitching passing through the body fabrics and across their abutted edges and through the margins of the tape.

In testimony whereof, I have signed my two subscribing witnesses.
