HEMMED ARTICLE AND METHOD OF MAKING THE SAME Filed April 28, 1949 1. flffazna y Patented May 27, 1952 UNITED" STATES PATENT OFFICE HEMMED ARTICLE AND METHOD OF MAKING THE SAME John P. Enos, Union, N. J assignor to The Singer Manufacturing Company, 'Elizabeth, N. J a corporation of New Jersey Original application February 20, 1948, Serial No. 9,678. Divided and this application April 28, 1949, Serial No. 90,070

' 4 Claims. (01. 112262) 1 This invention relates to improvements in hemmed articles and methods of making the same. An attachment designed to be applied to a family sewing machine to adapt the machine automatically to make hemmed articles as shown in this application and to performthe hereinafter described method, forms the subject of my pending United States patent application Serial No. 9,678, filed February 20, 1948, of which this application is a division. It is to be understood, however, that the articles may be made, and the method may be performed, by other means or, if desired, by hand, and that therefore the invention disclosed and claimed in this application is not dependent upon the attachment disclosed in the parent application.

Inasmuch as the articles disclosed in this application are products of the method herein described and claimed, and as the performance of the method necessarily produces the articles, it is obvious that the articles and the methods are one and the same invention.

One of the objects of this invention is to provide an improved folded and stitched hem for articlesof wearing apparel, and other articles, in which the stitches which secure the hem to the body of the article willbe either completely hidden at the outer side of the article or will appear only inconspicuously at widely spaced intervals, dependent upon the thickness of the work.

Another objectof the invention is to provide an improved method of making a folded and stitched hem as above described.

Still another object of the invention is to provide an improved method of making a folded and stitched hem which may be performed either by hand or by a conventional sewing machine.

Drawings depicting the improved hemmed articles and the steps comprising the method of producing the hems are annexed and form a part of this disclosure.

In the drawings, Fig. l is a sectional perspective view of a relatively thin workpiece folded in substantially Z-shape with one marginal portion thereof extending beyond the fold-edge proximate thereto and showing, in dotted lines, the marginal portion folded back to place the edge portion thereof between the fold-plies.

Fig. 2 is a sectional perspective view showing the folded workpiece disclosed in Fig. 1 as having the hem fold thereof stitched in accordance with the present invention, the lower portion of the figure showing the workpiece as it is folded and stitched, and the upper portion of the figure showing the body portion of the workpiece turned over to the right to ekpose the outer face of the hemmed article. 7

Fig. 3 is an enlarged sectional view taken on the line 33 of Fig. 2 showing the hem-attaching stitches passing through two of the superimposed plies back of the fold-edge and thus appearing on the outer face of the work as shown in the upper portion of Fig. 2. r I

Fig. 4 is a view similar to Fig. 1 but with thicker material and with the marginal portion projecting straight beyond the fold-edge and not turned back between the fold-plies as in Fig, 1.

Fig. 5 is a sectional perspective view of the material shown in Fig. 4 and showing the fold-edge attached at intervals to the projecting marginal portion of the workpiece by blind stitches.

.Fig. 6 is an enlarged sectional viewtaken on the line 65' of Fig. 5 showing one of the lateral stitches as formed in the fold-edge and anchoring-the fold-edge to the projecting marginal portion of the workpiece and the connecting straightaway stitches formed solely in the marginal'portion.

Referring first'to Figs. 1, 2 and 3 the workpiece wis folded into flat Z-shape, comprising plies I, 2 and 3, and the projecting marginal portion m of the ply I is folded back, as indicated by the arrow as, and the free edge m thereof is inserted between the fold-plies I and 2. With the plies thus folded groups or lines of straightaway stitches s are formed through the folded marginal portion m closely adjacent and parallel to the fold-edge 6 connecting the fold-plies 2 and 3.

Intermediate each two adjacent groups of straightaway stitches there is formed one or more lateral stitches t through the fold-edge e, the marginal portion m, and the ply I. These lateral stitches anchor the fold-edge e to the marginal portion m and secure the edge portion m thereof between the fold-plies l and 2. In material which has sufficient thickness to enable the needle to split it, the stitches 25 may be made in the fold-edge e as shown in Fig. 4 without passing through to the opposite side of the ply 3. When the material is relatively thin the stitches t may pass through the plies 3 and 2 and appear at the outer face of the article when it is opened out, as indicated in the upper portion of Fig. 2. These stitches t, however, are small and are located at widely spaced intervals and are, therevention. 7 As shown in tion m has a salvage.
