HINGED HALF SOLE.

Application fi ed. E'cbruary 21, 1925.

T 0 all whom it may concern:

Be it known that I, HELIAs P. TSELENTIS, a citizen of the Republic of Greece, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hinged Half Soles, of which the following is a specification.

It is well known that hides of leather often differ materially from each other in the matter of durability when subjected to wear. and that there is frequently a marked difference in such durability between various portions of the same hide, with the result that the variable wearing quality of the leather is often carried into the half-soles of the same pair of shoes whereby the half-sole of one shoe will wear out much sooner than the other.

The object of this invention is to out both half-soles of every pair from the same hide and also from ,the same part of the hide, and to so unite the two half-soles of a pair by means of an integral hinge of the leather thatthey cannot accidentally become separated, but must remain united until cut apart by the shoemaker just preliminary to his applying them to the shoes.

A further object is to cut the half-soles in pairs with a minimum waste of leather, and so the soles of a pair will fold together compactly and accurately.

Other objects and advantages will appear in the following detailed description.

In the accompanying drawing illustrating my invention, Fig. 1 is a plan view of a section of a side of leather and illustrates the lay-out of half-soles in hinged pairs thereon according to my preferred method. Fig. 2 is a perspective view of a finished pair of such half-soles folded together. Fig. 3 is a perspective view of an unfolded pair of half-soles with the hinge at their heel ends. Fig. 4 is a like view of same in folded relation, and Fig. 5 is a section through the hinge-of a pair of half-soles.

My improvement consists in cutting two half-soles comprising a right and left as indicated respectively by the numerals 1 and 2 arranged as shown in 1, with their outer sides contiguous and joined near their heel-ends by a hinge 3. These half-soles are Serial No. 10,766.

formed by the aid of av die which cuts both half-soles of a pair at once, but at the place for the hinge the die is so appropriately shortened as not to cut entirely through, to i shoemakers knife in separating the soles and to make the separation easier and the hinge more flexible, particularly when made out of thick, stifl. leather.

While I have shown the hinge connection between the half-soles of a pair at only two different locations, it is obvious that this connection can be made atother places, but I have given these thepreference because I have found that the resulting product can be cut withless waste of leather when so hinged than in any other arrangement that I have tried. It is not my desire, therefore, to prescribe the relative positioning of the half-soles to each other nor the location of the hinge connection between them.

What I claim as new and wish to secure by Letters Patent, is

1. A. pair of half-soles formed from adjacent portions of the same material and connected by an integral hinge of less thickness formed by cutting part way through said material and folded together on said hinge.

2. A pair of half-soles formed from adjacent portions of the same material and connected by an integral hinge of less thick.- ness formed by cutting part way through said material, said material being completely severed for an appreciable distance on each side of the hinge insubstantial alinement with the hinge and said half-soles being folded together on said hinge.

Signedat Indianapolis, Marion County, State of Indiana, this 19th day of February, 1925.
