SHOE AND METHOD OF MAKING'SAME Filed Sept. 22, 1937 l INVE/YTUR; Jam KLFUBHL/F Patented July 26, 1938 PATENT OFFICE SHOE AND METHOD OF MAKING SAME Jacob Klaubauf, Berlin-Halensee, Germany Application September 22, 1937, Serial No. 165,002 In Germany February 3, 1936 2Clalms.
My invention relates toshoes and a method of making same, and more particularly to shoes wihth plaited uppers and a method of making such s oes.
One object of my invention is to provide a shoe with plaited upper, which combines the flexibility of usual shoes having plaited uppers with the strength of shoes having a welt stitched to an outer sole.
In order to carry out my invention into practice, I use a method of making shoes with plaited uppers, which comprises the steps of preparing an upper of plaited strips on a last, applying a substantially U-shaped'flat welt provided with holes to the bottom of said last, placing a filler into-the space surrounded by said U-shaped welt. applying a piece of fabric with a shank piece connected to one of its ends on said flller and said welt and attaching said piece of fabric to said welt, lacing said strips through said holes in the welt, cementing an outer sole to said piece of fabric and said shank piece, and stitching said welt to said outer sole exterior to said holes. A shoe made according to my new method has no inner sole, so that the flexibility of a shoe with plaited upper is maintained, while its strength is increased by the arrangement of the welt.
The above mentioned object and advantage as well as other objects and advantages will be more fully disclosed in the following specification reference being had to the accompanying drawing forming part of this specification, in which Fig. 1 is a cross sectional view of the last with the plaited upper and with a U-shaped welt ap-' plied thereto,
- Fig. 2 is a fragmentary bottom plan view of the last and welt shown in Fig. 1,
Fig. 3 is a cross sectional view of the last with the plaited upper, the U-shaped welt, a flller inserted in said welt. and a piece of fabric holding said filler in said welt,
Fig. 4 is a bottom plan view of the parts illustrated in Fig. 3, showing the shank piece connected to the piece of fabric, portions of this piece of fabric being folded back or broken away,
Fig. 5 is a cross sectional view of the lastwith the plaited upper, the welt, the flller, the piece of fabric carrying said flller, the outer sole, said welt I being stitched to said outer sole, and a lining covering the filler and the welt,
Fig. 6 is a perspective view of the finished shoe. on a last a the upper b is plaited in known manner by means of leather straps, cords, bands or the like. A U-shaped fiat-welt it made 'of leather and provided with holes c (Fig. 2) is applied to the bottom of said last a and is temporarily tacked to the same. Subsequently to or simultaneously with the application of the welt d, a flller j, which may be made of sponge rubber for example, is inserted into the space surrounded by said U-shaped welt (see Figs. 3,4 and 5). In order to hold this flller in its position a piece of canvas or linen g projecting over the contour of 1 the filler is applied to said flller and said welt 10 and is attached to the latter (Figs. 3. 4, 5). The end a of the piece a of fabric, which projects from the edges of the welt and the flller is connected to the usual shank piece h which extends to the heel seat of the shoe (Figs. 3 and 4) The '16 straps forming the plaited upper are then laced through the holes e of welt d. The straps are usuallycontinuous; if there are ends. they are tied below the welt (Figs. 1- and 3). The quarter of the shoe is then tacked in the usual manner to the 20 Owing to the omission of the inner sole the 30 footwear has the light weight and flexibility of a shoe with plaited upper. As, on the other hand, the upper is connected with the outer sole by the welt, the high strength of a welt shoe, is
imparted to the footwear. The sponge rubber 36 layer employed as flller provides a soft support for the foot.
As, however, the straps or strap ends laced through the holes oi the welt are not touchedby 40 the seam which connects the welt with the sole, they are protected against damage or destruction.
