WILLIAM F. LAUTENSCHLAGER, OF CINCINNATI, OHIO, ASSIGNOR T LORENZ MUTHER, 0F NEWTON, MASSACHUSETTS.

MEMBER FCR SHOE-UPPERS.

Application iled October 20, 1917. Serial No. 197,611.

. To all whomit may concern:

Be it known that I, WILLIAM F. LAUTEN- SCHLAGER, a citizen of the United States, and

residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented .v

a new and useful Member for Shoe-Uppers,

of which the following specification is a fulll disclosure.

My invention relatesv to a member for Aa shoe upper, or similar article, where two sheets are to be held together for unitary manipulations, in a manner permittingsome degree of relative movements of thesheets, as in the folded margin of a shoe upper.

The object of the invention is to produce a sheet article, such as a shoe upper part, comprising superposed shoe parts, such as the margins of a shoe upper, adheslvely united to an intermediate member, such as a folded tape, enabling the superposed parts to be manipulated as a unitary member, while providing slight relative movement between the superposed members.

` The features of the invention will be more fully set forth in the description of the accompanying drawings, forming a .part of this specification, wherein:

'Figure 1 is a perspective view, partly in section, showing a lasted shoe upper.

showing my method of edge folding.

Fig. 3 is an enlarged perspective section, showing the skived portion ofthe marginal edges.

Fig. 4 is an enlarged perspective section of the folded adhesive tape used in my method.

Fig. 5 isy an lenlargedperspective section on line ff-V5, Fig. 2. 1',

Fig. 6 isan enlarged perspective section on line 6-6, 2. y

. Fig. 7 is an enlarged perspective section on line 7-7, Fig. 1; v

The finish edges of shoe uppers, generally, terminate in skived edges and such edges are ordinarily folded inwardly and secured by cement. This cementing operation is eX- pensive and slow and is frequently ineffective for retaining the edge in folded condition during the subsequent stitching operation.

The method I preferably `employ for producing my new article consists in taking a strip of tape folded upon itself to constitute the insert l, only-the exterior surfaces having adhesive application, much cheaper than cement. skived portion 2 with free` edges 3 coincident to the line of fold and the folded tape edge 4 pointing inwardly. The skived portion of the upper is bent over this insert, as indicated in Fig. 5, both inner surfaces ofthe` upper margin being adhesively' secured to and retained by the adhesive surfaces of the folded tape, the normal line'of finishing stitches being shown by dotted lines 5, Fig. 5. This'ins'ert and folding operation can either be done by hand or machinery, and, if the latter, the tape folding and inserting can be run along cordinately with the ma?v chinery for folding over the upper margin'.

This constitutes a satisfactory, temporary securance, the process is much cheaper and cleaner than the cementing treatment and the finished product is better because the margin is advantageously reinforced by this folded tape insert. 1

The member so made is primarily inan upper, tip, or vamp, or to long curves, and is not intended particularly for relatively vsharp curves. As, for instance, vthe same method and structure may be employed for the vamp edge 6 and tip edge 7, and the saving of labor are material items.

The outer surfaces of thel folded tape when moistened adhere to the inner-.folded surfaces of the upper and so constitute a This insert is placed along the tended for application to straight edges of- 1 marginal reinforcement of value in preventing the stitches from pulling out, and also produces a superior finished appearance as well as a more durable shoe. ,v

The fiat character of the folded tape insert, provides a reinforced margin `into which theneedle of the stitching machine will readily take, drawing the stitch through two thicknesses of the upper, vamp ort'ip, and the two wings of the folded tape, forming a stout stitch anchorage. The tape may be wide enough to project below the folded over upper edge,'or it may terminate flush with this vdown 'turned upper edge. Preferably a wide tape is employed inthe folded top edge 8 of the shoe upper. This wide tape extends approximately twice the width of the fold (see Fig. 6), and when the lining 9 is assembled with the upper, the eX- posed portion l() of the adhesive tape surface is moistened, serving as an anchorage gina1edge lfolded over,

Fig. 7), and as a reinforcement for the top of the inished shoe. Y

Having described my invention, I claim z- 1. A shoe upper member having a marand a vfolded tape having adhesive exterior surfaces secured within the shoe material' fold, the folded edge of the tape being outermost.

2. A shoe upper member havin'g a marginal edge folded over, and a folded tape having adhesive exterior surfaces, lying within the folded margin, the folded edge ofl the tape coinciding with the turned over edge of the material, of the tape coinciding with the fold of the material. y i

3. A shoe upper member having a margin folded upon itself, andl an adhesive tape placed within the fold to aline a medial free portion of the tape with the turned edge of the upper member. f

and the double edges 2l. sheet article of the nature disclosed, having. a base member and securing them together and' placed to aline a medial free portion of said member with the edge of the member overlying the base member.

5. -A sheet article of the nature disclosed, comprising superposed members, and a flexible intermediate adhesive member uniting the superposed members and having a medial free portion permitting slight relative movement between the superposed members.

In witness whereof I hereunto subscribe my name, as`attested by the two subscribing witnesses.
