UNITED STATS JOHN 1v1. snNDnAN, or HiNcKnnY, MrNNnsoT-n.

Application filed July 6, 1922.

To all whom t may concern Be it known that I, JOHN M. SUNDEAN, a citizen of the United States, residing at Hinckley, in the county of Pine and State of Minnesota, have invented anew and useful Seam, of which the following is a specification.

This invention relates to seams and more particularly to seams for leather goods such as shoes, mittens, baggage carriers and the like. v

The object of the invention is to provide a flat seam of this character which is strong and durable and will not rip and by means of which two pieces of leather may be stitched together and the stitches concealed without using any cover strip to effect such concealment. Y

Another object is to provide a seam for connecting two `pieces of leather in which one piece is slit on its inner face to'provide an attaching lip which is secured to the otherv piece by a row of stitching passing through the lip at the base thereof, andV through the edge of the other piece so that when the parts are in Operative position, a fiat seam will be formed with the stitching `invisible from both the inner and outer faces of the device formed by the connected leces.

With the foregoing and other objectsinV view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed maybe made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawin 5:-

Fig. l is a transverse section s owing one form of the invention.

Fig. 2 is a detail transverse section showing the seam with the parts connected thereby in the position which they assume before being arranged fiat in their normal position.

serial No. 573,144.

Fig. 3 is a detail transverse section showing still another form of the invention, and .50

Fig. 4 is a detail sectional view with the lips illustrated in Fig. 8 shown open ready for stitching. Y

In the form shown` in Figs l and 2, the leather pieces la and 5tL are connected at a point spaced inwardly from the edge of the v face of the member 5a. After this edge of the member laL has been stitched in the manner above described, the plece laas folded over into the position shown in Fig. 1 and `the lining strip 4 securedover the seamso formed by Va row of stitching passing through one edge thereof and through the member-ln at ak point spaced laterally from` the connection with the lip 8 and through the edge of the member 5" The strip 4 is, y also secured tothe member 5a on the other c side of its seamed connection with member lak by a row of stitching 12y which also o erates as a finish as well as to secure tle strip 4 in position.

By stitching the edge l() of member la to the lip 8 at the base thereof, the stitching kwill be invisible from 'the outerface of the connected parts and when the member lai 'is folded over in the position shown in Fig. l it will also be seamed on the inside.,

In the formshown in Figs. 3 and 4, the members lb and 5b. are connected similarly to those shown kin Figs. l and 2 with the addition of asecond seam formed by an attaching lip 13 arranged adjacent the member lb by a row of stitching 14 passing through said member and through the base of the lip.

From the above description it will'be obvious Vthat aseam constructedas herein shown andrdescribed in addition to having `the connecting stitches concealed tov prevent Wear by rubbing on the stitching also is greatly strengthened and ripping thereof will be prevented.

I elaiim-V t The combination of two pieces of leather,

one of which is split longitudinally on its Y inner face at a point spaced from its edge to provide an attaching lip, a row of stitches passing through the edge of the other piece and said lip at the base thereof, the projecting edge portion of the lip-carrying piece being turned down .iat over the seam so formed andV secured, whereby the stitches are rendered invisible from bothkfaoes of the so connected pieces,

In testimony that I Claim the foregoing as my own, I have hereto aiixed my Signature in the presence of two witnesses.

JOHN M. SUNDEAN.
