2 Claims.

This invention relates to counter portions of shoes and has for an object to produce such portions provided with stiffeners which it is not necessary to mold prior to assembly in the uppers.

Certain types of stiffeners such as those having Woven fabric foundation do not have suicient stretch for successfully molding to the desired contours for counters and those which are more suitable for molding are liable to produce in the molding operation bunching of the material, more particularly along the rear lower edge, and thinning of the material at other parts, which causes them to be unsatisfactory.

In accordance with the present invention the stiifener is made in two parts, each forming one side of the stiifener and each with a convex rear edge, these edges being united in a butt joint. In order to permit a relatively smooth outer face of the stiifener at the joint the two parts may be stitched together inside out along their rear edges by a zig-zag over-edge stitch. The parts being tempered, the stiiiener is turned right side out with the rear edges of the parts brought into butting relation, thus exposing only unobjectionable laterally extending stitch lines across the joint on the outer face of the stiffener.

For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a perspective showing one form of the stiifener ready for assembly in the shoe upper.

Figure 2 is a side elevation of the parts before the turning operation.

Figure 3 is a detail section on line 3 3 of Figure 2.

Figure 4 is a section similar to Figure 3, but showing the parts turned but with the adjacent edges not in iinal positions.

Figure 5 is an elevation showing a manner of bringing the edges of the parts into butting relation after the stiifener has been turned.

Figure 6 is a detail section on line 6 6 of Figure 5.

Figure 7 is a fragmentary perspective showing the stiffener parts being fixed together in a different manner.

Figure 8 is a side elevation of the saine.

Figure 9 is a View similar to Figure 8 but showing the parts with the securing operation nearly completed.

Figure 10 is afragrnentary perspective showing the parts attached.

Referring to the drawings, a pair of members cut to the shape of opposite sides of the desired counter stiifener such as 1 and 2 and provided with convex rear edges as at 3 and 4, respectively, are arranged in superposed relation inside out and stitched together along their rear convex edges as by a line of zigzag oversearn stitches 5. The rear portion of the stifiener is then tempered, the particuiar means of doing this depending on the type of stiifening agent employed, and the stiffener parts are then turned right side out as shown in Figure 4, the edge portions 3 and 4 being brought into cutting relation. This may be accomplished, as shown, for example, in Figures 5 and 6, by sup i porting the stiifener along the line of stitching 5 on the cmved upper face 10 of a standard 11 secured to a work bench or other suitable support l2 as by bolts 13, and pressing the reai` portion 10 of the stiifener along the stitch line against this upper curved edge as by means of a pressure roller 14 which may be provided with a handle l5 which the operator may grasp. When this has been accomplished the stiifener may be tempered [.75 throughout, assembled in the upper of the shoe'v* and lasting effected.

The pressure of the upper on the last during the lasting operation causes the counter stiffener, which is still in temper, to be conformed closelyggo to the last contour so that when the stiffener is permitted to set it is in the desired shape. By forming the stiifener in this manner only the lateral or horizontal stitches produced by the overseaming operation are exposed on the outer 35 face of the stiifener, these being so smooth andt" inconspicuous as to produce no detrimental effect in the shoe, the crossed stitches lying on the inside face. The adjacent edges of the stiffener parts being in butting relation, no undesirablego thickening of the stiffener at its rear end is produced which might cause discomfort to the wear- Y er. By uniting the parts along their curved rear edges the stiifener is given an initial configuration which permits it to be conformed to the last A with little stretching and produces no trouble-'W' some bunching of the stiifening material at its lower edges or thinning of the material at any portions of the counter. It likewise makes possible the use of stiffeners having Woven fabric, foundations such as those made of one or more layers of cloth stiifened with cellulose esters or similar solvent-softened stifening agents. This invention is, of course, also applicable to counters employing a thermoplastic or other stifening. .105 agent.

In Figures 7 to l0 another method of securing the stiffener parts together with their rear edges in butting relation is illustrated. In this meth- 0d no turning of the parts after the stitching opy; l110 eration is necessary. The curved edges of the stiener are arranged in butting relation at one end as shown in Figure '7, and they are stitched together starting at this point with zigzag stitches. The sewing machine for effecting this stitching operation is shown as provided with a pair of Work-engaging conical rollers 20 suitably mounted on arms 2l and spaced sufficiently to permit the passage of the lateraly movable needle 22 Which descends alternately on opposite sides of the abutting edges of the stifener parts in making its sewing strokes. As the stitching proceeds the abutting edges of the stifener parts are brought together progressive- 1y causing the rear portion of the stiiener to assume a curved contour at the line of stitching as shown at 25 in Figures 9 and 10. Figure 8 shows in side elevation the positions of the parts adjacent to the starting of the stitching operation, as the stitching progresses the stiiener parts are rocked about their lower edges into the position shown in Figure 9. At 26 in Figures 8 and 9 is shown the feed plate by which the work is fed with relation to the needle. Such stitching produces a line of zigzag stitches on the inner face of the stiffener shown at 27 in Figure 10 which secure the stiffener parts to each other in butting relation and right side out so that no subsequent turning or pressing operation is necessary to complete the formation of the stiffener. On the outer face of the stiffener the stitch lines are similar to those shown in Figure 5.

As shown in Figures 1 to 6 the counter portions are made from superposed laminations some of which at least are of Woven fabric, the whole being stifiened p-referably with a cellulose ester though it should be understood that the invention is not limited to the use of such material and that various other modifications andchanges might be made therein without departing from the spirit or scope of this invention as dened by the appended claims.

I claim:

1. A counter stiffener comprising two parts each having a convex rear edge, and means for joining said parts together with said rear edges in butt joint relation.

2. A counter stiffener comprising two parts each having a convex rear edge, said parts being joined together with said rear edges butted together by zigzag stitches, the cross portions of said stitches lying on the inside face of said stiffener.

WILLIAM I-I. BAYNARD.
