METHO OF MAKINGWELTING 0B THE LIKE.

Application led January 11, 1927. Serial No. 160,444.

The present invention relates to boots and. shoes and more particularly to welting and the method of making welting and the mainobject of the inventlon is the economical treating of leather'strips to form weltlng having the desiredcharacteristics. y y A further object of the invention is the economical manufacture of welting of the caulk or water-proof type. p

Another object of the invention is theprovision of a welt having a serrated edge.

Other objects of the invention will be apparent from the following description.

According to the present invention a strlp of leather or equivalent material is cut on both sides of a longitudinal median line and strips of leather of substantiallyrectangular cross section are removed leaving the strip of leather having a longitudinal central rib. The strips of leather thus removed may be used in the manufacture of boots and shoes as is well known to those skilled in this art. The remaining strip is then cut into two strips' preferably of equal width thereby producing two strips of identical characteristics, each of Ithese strips havin a marginal raised or flanged' portion the e ge of which being subsequently subjected to an ironing by a heated roller to impart to the lesh portion of the leather the appearance of the grain portion. y,

According to one form of the invention, the centrally ribbed strip is subjected to the action of a cutter which simultaneously divides the strip into two welt pieces as above described and also imparts to the edge of the marginal flange a serrated surface.

For amore completeunderstanding of the invention reference is to be had tothe following description and to the accompanying drawings forming a part of this specification.`

vIn the drawings Fig. 1 is a fragmentary view of a strip of' leather or the like; v v

Fig. 2 is a view of the strip shown in Fig. 1 after the first operation has been performed; v

Fig. 3 is a view of the centrally ribbed strip divided into two welt pieces of identical characteristics each having amarginalv flange the edge of which is serrated; Y

Fig. 4 is a view of single welt piece having a marginal iiange with a serrated edge Fig. 5 is a view of the centrally ribbed strip divided into two welt pieces of identical characteristics each having a marginal 'fiange with a plane surface; v

F1g. 6` 's a view of a single welt piece having a mar inal flange the edgeof which is a plane sur ace;

Fig. 7 is a sectional view of a shoe having the serrated edge caulk welt shown by Fig. 4 applied tothe shoe so that one side of the caulk welt lies liat on the usual welt; and

Fig. 8 is a view similar to Fig, 7 but shows theserrated edge caulk welt applied to the shoev so that one side abuts the shoe upper and the otherlside is at an angle to the usual welt.

Referring to thedrawings in detail, Fig.

1 shows a fragment of a strip of leatherwhich is subjected to the hereinafter described process to produce the strips of the desired characteristics. The strip 10 is iirst treated to remove therefrom marginal strips of substantially rectangular cross section leaving a strip llfg shown by Fig. 2, having a central rib 12.

The strip 11 is then ldivided into two pieces 13 and 14 of substantially identical characteristics, each of these stri s comprising a welt piece having a margins.V raised portion or flange 15 the edge of which is serrated as designated by the reference i character 16. The cutter employed for dividing the ribbed strip 11 is such as to simultaneously form the flanges 15 with the serrated edges. Fig. 4 shows a strip or welt piece having a flange with a serrated edge. In my co-pending application, Ser. No. 160,443, filed January 11, 1927 I have shown an improved machine for simultaneously dividing the strip 12' or,`

a similar strip and serrating the edge of the resulting il'anged welt piece.' i

The stri 1-2 may be divided into two weltl pieces as s ownl by Figs. 5 and 6, each of the welt pieces having Va marginal flange the edge of which is substantially a plane surface.y For this purpose the strip 12 is cut along its longitudinal median line forming two strips-,17 and 18 leach having a mar 'nal flange 19. The edge of the marginal ange may subsequently be subjected tothe ironing action of a heated roller for imparting thereto the appearance of theJ grain side of the leather.

, Fig. 7 shows a welt piece 13 or 14 a plied,

to a shoe. The flanged portion 15 lies at on the Goodyear welt 20 and abuts the shoe upper. Fig. 8 shows the welt piece applied to the shoe so that the flange portion abuts the shoe upper and is at an angle to the Goodyear welt 20. It is thus apparent that the appearance of the shoe may be chan ed terial. While the strips 13 and 14 are shown such as the strip 10 maly as ianged it will be understood that a strip be divided along a longitudinal margina line by a cutter which also serrates the edges of the resulting strips. It is preferred, however, to form the welt pieces with marginal flanges as shown Fig. 4. l While I have shown and described the preferred embodiments of the invention, it is to be understod that certain changes may be made without departing from the invention as dened by the appended claims.

Having thus described the invention, what I claim and desire-to secure by Letters Patent of the United States isz- 1. The method of treating a strip of leather or the like to form a plurality of welt pieces comprising removing from a face of said strip adjacent both of its longitudinal edges strips ,of substantially rectangular cross section leaving a strip having a longitudinally extending central rib and dividing said ribbed strip along a longitudinal median line forming two welt pieces of idenv tical characteristics.

. 2. The method of treating a strip of leather or the like toform a plurality of welt pieces comprising the step of removing from a face of said strip adjacent both of its lon'- gitudinal edges strips of substantially re- The strips 13 and 14.

tangular cross section leaving a strip having an intermediate longitudinally extending rib.

3. The method oftreating a strip of leather or the like which strips adjacent both longitudinal edges thereof leaving a strip that is thicker at its central portion than at its edges, and dividing said strip along its longitudinal median line forming two welt pieces.

4. The method of treatin a strip of leather or the'l'ike to form a plura it of welt pieces comprising the removing o strips from a face thereof adjacent both longitudinal edges leaving a strip having a longitudinally extending rib intermediate the edges of said strip, and simultaneously dividing said strip throu h said rib along a longitudinally exten ing dividing line and serrating the edges of the resulting strips'adjacent said dividing line.

comprises removing v 5. The method of treating a strip of leather or the like to form a plurality of welt pieces comprising removing strips adjacent both longitudinal edges leaving a strip that' is thicker at its central portion than at its edges, and simultaneously dividing said strip along a longitudinal median line and serrating the edges of the resulting strips.

6. The method of treating a strip of leather or the like comprising the step of reducing the thickness of the strip near its longitudinal edges leaving a strip that is thicker at its central portion than at its edges, and dividing said strip longitudinally through said thicker portion.

' 7. The method of treating a strip of leather or the like comprising reducing the thickness of the s'trip adjacent the longitudinal edges thereof and subjecting an intermediate thicker portion of the strip longitudinally thereof to the action of a sei-rating cutter.

In witness whereof I hereunto alix. my

signature.
