ONE-PIECE SELF-BOUND POCKET Filed June 29, 1956 3Q //Vl/EN7'O Q= 29". 6/405 L. 3/9/45) g 534 By WW United States Patent 3,150,382 ONE-PIECE SELF-BOUND POCKET Gillie L. Briley, Nashville, Tenn., assignor to W. E. Stephens Manufacturing Co., Inc. Filed June 29, 1956, Ser. No. 595,010 1 Claim. (Cl. 2-247) This invention relates to a one-piece self-bound pocket and its method of fabrication.

More particularly the invention pertains to a one-piece, continuous, self-bound pocket (in contradistinction to a conventional tape-bound pocket) and its method of fabrication. The pocket is formed of a one-piece blank folded, to form a swing-type pocket, about a vertical mid-line for side pockets and about a horizontal mid-line for hiptype pockets. The pocket blank is cut, so that when folded, one of the blank halves extends beyond the edge (or edges) of the other half to define a marginally extending binding strip (or strips) corresponding to the seam (or seams) to be formed in the pocket before assemblage thereof with the garment. The extent of the marginal strip is such that it can be double-folded and simultaneously stitched to form a four-thickness seam in a single sewing operation. The raw edges of the seam are thus brought together adjacent the edge of the pocket and self-bound by the double-folded and stitched marginal extension strip.

Swing-type-pocket construction has long presented serious problems in design and cost to the garment industry. The stitching-and-turning method not only requires a second operation but provides a pocket having undesirable fraying edges presented on the inside of the pocket. Single-stitching on an over-stitching machine produces a seam lacking somewhat in attractiveness but is principally objectionable because the chain stitch inherent in such an operation tends to break and/ or pull out, producing a total failure of the pocket. The use of binding tape to cover the cut seam edges requires both additional material and additional operations to anchor the ends of the applied tape.

It is accordingly the principal object of the present invention to provide a swing-type pocket formed of a foldable blank of such configuration that one or more of its seam-forming edges provides a binding extension that can be double-folded and simultaneously sewed in a single operation to provide a self-bound pocket element.

This and other objects and advantages of the invention will become apparent as the following detailed description thereof proceeds.

In the drawings:

FIG. 1 is a plan view of a pocket blank for front or side pants pockets.

FIG. 2 is a plan view of the blank of FIG. 1 folded and stitched to form a pocket element.

FIG. 3 is a fragmentary elevation in section taken on the line 33 of FIG. 2.

FIG. 4 is a plan view of a hip-pocket-forming blank.

FIG. 5 is a plan view of the blank of FIG. 4 folded and stitched to form a pocket element.

With reference now to FIGS. 1-3 of the drawings, a one-piece pocket blank 11 preferably of fabric, is disclosed having a pair of substantially symmetrically-shaped portions or panels 11a and 11b, symmetrically formed about the fold line 13. The panels 11a and 11b are provided with substantially co-extensive mating marginal edges when the panels are folded upon each other in super-imposed relation, as shown in FIG. 2. The entire marginal edge of the panel 11a, which is adapted to be secured to the corresponding mating edge of the panel 11b, is provided with an extension, such as strip 15, which is substantially uniform in width. This extension 15 is formed throughout the length of the marginal edge of the panel 110, which does not constitute any part of the fold line 13, any part of the pocket opening between the panels 11a and 11b, nor the upper marginal edge which is adapted to be secured to the garment.

After the panels 11a and 11b are folded against each other about the fold line 13, the extension 15 is then double-folded, as disclosed in FIGS. 2 and 3. The extension 15 is folded once closely over the corresponding mating marginal edge of the panel 11b, and folded again upon itself to form an outer portion or ply and an inner portion or ply including the raw edge of the extension 15 between the outer portion and the panel 11b. The folded portions of the extension strip 15 are preferably about equal, so that the raw edge of the strip 15 will be in substantial alignment with the corresponding raw marginal edge of the panel 11b, and both raw edges will be located at the outer extremity of the pocket 11 and completely enclosed by the strip 15. The marginal edge construction disclosed in FIGS. 2 and 3, forms a seam S having a four-ply or four-panel thickness. The seam S is secured by a double row of stitching 17, although any desired number of rows of stitching, more or less than two, may be employed to secure the seam S.

The notches shown at 19 in FIG. 1 are conventional expedients for facilitating the sewing of the pocket element of FIG. 2 into the garment. The phantom-lineenclosed area in FIG. 2 represents the cut-back at 11d where the pocket attaches to the garment in a known manner.

In FIGS. 4 and 5 the numeral 21 generally designates the pocket blank, which has the outer and inner portions 21a and 21b, respectively, foldable about the mid-line 23 to form the pocket element of FIG. 5. Guter blank portion 21a is provided with the usual inside facing element 25 secured by stitching 25a. The blank portion 21a has binding extensions, such as extension strips 27, which when folded over and stitched into place by stitches 29, as shown in FIG. 5, form the bound seam S (having the same construction as the seam S in FIG. 3). While the extending margins 27 are shown as being formed on the outer pocket portion 21a, it is apparent that the same could be formed equally well upon the inner pocket portion 21b if preferred.

The centrally and horizontally disposed part 30, secured over the end edge of the portion 211) by stitching 30a in FIG 5, is the welt facing of the pocket by which the same is joined to the garment, in a known and conventional manner. The optionally usable stitching 31 at the bottom of the pocket of FIG. 5 has two important functions: first, it provides a quick and effective manner of carrying the stitching operation to the second side of the pocket element without removing the pocket-blank material from the sewing machine, and secondly, it provides additional strength for the pocket at the bottom thereof.

While I have disclosed certain preferred embodiments of my invention, it is to be understood that many changes can be made in the size, shape, composition and arrangement of the parts and in the sequence and nature of the method steps without departing from the spirit of the invention as defined by the subjoined claim.

Having thus described my invention, I claim:
