SEA-M FOR SEWED ARTICLES- Application filed February 18, 1899. RenewedkTuly 27. 1901.- Serial No. 89,990.

To all whom it may-concern:

Be it known that I, JOHN G. LEWIS, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have in- Vented a certain new and useful Hem or Seam for Sewed Articles, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same,

reference bein hadto the accompanying drawings, forming part of this specification.

The object of my invention is to make. a

hem or seam for sewed articles which will be neat in appearance'and durable. My lnventlon conslsts in a hem or seam for sewed articles, in which a portion of the material is folded upon itself and the folded portion secured to the main part of the material by blindstitches piercing said material in the direction of the length of the hem, and in other novel features which are described in the following specification and pointed out in the claims affixed hereto.

In the accompanying drawings, whichillus- 1 trate a hem made in accordance with my invention, Figure 1 is a front view. Fig. 2 is a transverse section. Figs. 3 and 4 are sectional views showing the manner offorming the hem or seam, and Fig 5 is an enlarged view showing the form of stitcl1.

, Like marks of reference refer to similar parts in the several'views of the drawings.

10 is the main layer of the material. In the form of hem shown, a portion 11 is folded back upon the layer 10. This portion 11, however, may be a separate piece of material in some cases. The edge 12 of the portion 11 is preferably turned under, as best shown in Fig. 2, so that there will-be noraw edge exposedin the completed hem or seam. The

layers of cloth are then bent around a guide,

I shown by the dotted line A of Fig. '3. In

some instances the needle in passing down at the other side of the edge of'the-seam may pass throughthe

layers

11 and 12 and into the main layer 10. In most cases, however,
