2 Claims.

This invention relates to a positioning means, with particular reference to the types of construction employed for locating. a multiplicity of separate cross-pieces of leather in the manufacture of a shoe sole blank, or of positioning a leather vamp or other sheet of material against a gauge in a leather ornamenting die or the like, and it has for its object to afford a construction in which a positioning wall or gauge can be readily, economically, and accurately attached to a support and is characterized by maximum strength and durability.

Another object of the invention is to provide a construction including a positioning wall that can be easily attached in correct position to a supporting plate, that is permanently secured, and characterized by great strength and little likelihood of bending or damage from the handling and abuse it receives in the ordinary course of operation. e

Still an additional object of the invention is to alford a positioning wall that can be readily fabricated, quickly and accurately applied in proper position on its support, and securely attached and to accomplish these results by the utilization of a narrow flexible metal ribbon or strip that is corrugated transversely and secured edgewise to the supporting plate on which it is mounted.

A further purpose of the invention is to afford a structure to be used in positioning a multiplicity of separate leather pieces and cementing them to a supporting layer in such a way that the leather pieces forming a shoe sole blank can be readily inserted into the form and the sole blank easily removed after cementing, while any surplus exuded cement is provided for in a manner that does not clog the form or necessitate frequent cleaning.

Still an additional object of the invention is to afford a positioning form that can be used in conjunction with a rubber pressure pad without cutting the pad when pressure is applied.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear clearly from the following description when read in conjunction with the accompanying drawing, the novel features being pointed out in the claims following the specification.

In the drawing:

Fig. 1 is a plan view of a positioning form constructed in accordance with a preferred embodiment of the invention and designed to be used for positioning a multiplicity of separate leather cross-pieces for attachment to a supporting layer,

in the manufacture of a shoe sole blank; .l

Fig. 2 is a longitudinal sectional view on the line 2-2 oi Fig. 1, and

Fig. 3 is a plan view vof another adaptation'of the invention as applied'to a stripper plate forming part of a conventional leather ornamenting die.` v

The invention may be utilized. in the production of a leather shoe soleblankaccording to the method disclosed in my copending application filed November 20, 1942, SerialNo.. 466,385, although it also has other possible applications.

Referring more particularly Vtoithe drawing in which like reference vnumerals refer to the same parts throughout the several views and to Figs. 1 and 2, l designates a supporting plate provided with an opening '2 by means of which a shoe sole blank can be ejected after the parts are cemented and 3 designates the positioningwall that is shaped to surround the shoe sole blank, or the several cross-pieces of which it is composed.l

f The positioning wall.:3' is preferably .formed from a flexible transversely corrugated metal ribbon, or strip of material, that is positioned edgewise against the supporting plate I and attached in such position, affording a vertically corrugated wall perpendicular to the supporting plate. Such a metal ribbon or strip can be secured to the supporting plate with extreme facility by arranging it against a suitable guide employed for the purpose and soldering or spotwelding it in place while so located.

The corrugated strip is secured in place by suitable attaching material such as solder applied to the outside of the wall 3 at points acljacent to the supporting plate l and between the spaces afforded by the corrugations. In this manner, the solder or other attaching material filling in between the corrugations greatly strengthens the wall and increases its rigidity, a result that cannot be attained with a wall formed from a straight or uncorrugated metal strip, and the corrugated strip can be attached accurately in perpendicular relation to the supporting plate owing to the corrugated shape of the edge lying against the plate which insures its right-angular relationship to the support.

Where such a positioning form is used for locating separate cross-pieces of leather in fabricating a shoe sole blank, the use of a corrugated strip greatly facilitates the inserting of the crosspieces and their proper positioning within the form and equally facilitates removal of the blank from the form after the cementing operation is completed, owing to the positioning wall contacting the periphery of the blank or outer edges of the cross-pieces only at spaced intervals and thus avoiding sticking due to contact along excessive lengths. The spaces on the inner side of the wall aiorded by the corrugations also aiord recesses into which any surplus cement exuded during the pressure operation .can pocket Without affecting the inner contact points of the Wall with the leather pieces, and thus eliminating the necessity of too frequent cleaning of the form and removal of hardened cement.

When a rubber pad or mat is engaged with the upper edge of the positioning wall in applying.

pressure to a leather blank, there is less tendency of the corrugated wall to cut the rubberpad than if a straight or uncorrugated Wall were employed.

The structure canalso befus'ed as ag'auge in the conventional leather ornamenting die, as illustrated in Fig. 3, in which 5 designates a conventional stripper plate of a leather ornameniting die, 6 is a knife, and 1 the lperforating die, While 8 designates the gauge against which `a leather vamp or other piece of material is located and held during the ornamenting operation. In the present structure, the wall 8 consists of a transversely corrugated flexible metal ribbon or strip as shown, located edgewise on the supporting plate 5 adjacent to vthe slot 9 and held in place thereon by solder l0, or rother suitable attaching material.

Heretofore in constructions of this character, the gauge has consisted of a block or casting produced according to the desired shape and riveted to Ythe plate, Whereas withthe present arrangement, the flexible transversely corrugated metal ribbon is positioned edgewise on the plate 5 against a suitable form employed for the purpose and while maintained in predetermined position edgewise on the plate 5, it is permanently attached by the soldering operation, spot-welding, or otherwise.

This affords a simple, economical, and convenient mode of fabricating and attaching a gauge to a stripper plate of a leather ornamenting die, and results in a structure that is equally as strong and durable as the cast or other gauges heretofore manufactured and riveted to the supporting plates.

It will be understood that the stripper plate 5 and the parts shown in connection therewith are conventional in a leather ornamenting mechanism, the only novel part of the structure shown being the corrugated metal Wall or gauge 8 which is secured to the supporting plate to conform to a predetermined pattern, the leather material .being previously cutaccording to such pattern and located against the corrugated metal gauge when the ornamenting operation is performed.

While the invention has been described with reference to certain specic embodiments, it is not confined to the details herein disclosed, and this application is intended to cover such modifications or departures as may come within the purposes of the improvement and the scope of the following claims.

I claim:

1. A positioning form for shoe sole blanks and the like including a supporting plate and a transversely corrugated exible strip arranged perpendicularly thereon with one edge abutting and attached to the supporting plate, said strip being of a shape and height to extend around and engage the periphery of a shoe sole blank.

2. A positioning form for shoe sole blanks and the like including a supporting plate and a transversely corrugated exible strip arranged perpendicularly thereon with one edge abutting the supporting plate, said strip being of a shape and height to extend around and engage the periphery of a shoe sole blank, and. a body'of attaching material on the outer side of the corrugated strip adjacent to the supporting plate and occupying the recesses ainorded by the corrugations.
