SHOE SOLE AND PROCESS OF MAKJQNG THE SAME.

Application filed October 29, 1921. Serial No. 511,305.

To all whom it may concern:

Be it known that I, Mrcrme GONZALEZ Munoz, a. citizen of the Republic of Mexico, residing at Mexico city, Mexico, have invented new and useful Improvements in Shoe Soles and Processes of Making the Same, of which the following is a specification.

This invention relates to the art of shoemaking and has especial relation to a novel construction of shoe sole and the process of making the same.

The primary object of the invention is the provision of a shoe sole which is constructed so that its inner face is shaped to conform to the shape and character of the sole face of the shoe, so as to provide a perfeet fit and prevent the passage of moisture between the shoe and its sole.

For this purpose, the invention also includes means for making the sole, whereby this fit is obtained, the inner face of the sole conforming perfectly to the irregularities of the sole face of the shoe to which it is attached.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a bottom view looking at the sole face of a shoe and showing the inturned edges of the upper.

Figure 2 is a top View of a mould core made from this face of the shoe.

Figure 3 is a bottom view of the same.

Figure 1 is a longitudinal section through a mould with the core in place.

Figure 5 is an inner plan view of one mould member.

Figure 6 is a similar view of the other mould member.

Figure 7 is an inner face view of a sole made from the mould.

Figure 8 is a longitudinal section through the mould with a sole therein.

Figure 9 is a transverse section showing the sole attached to a shoe.

Referring to the drawings in detail, like characters of reference denote corresponding parts throughout the several views...

In carrying out the invention, the sole of the shoe is formed of some suitable composition which is capable of being moulded, the purpose being, as stated, to produce a shoe sole having a perfect fit upon the shoe. to which it is attached. In order to make this sole,'a mould is provided which will produce a sole whose inner face (that is, the face which contacts with the bottom) conforms perfectly to the shape and irregularities of the sole face of the shoe. To accomplish this the shoe, after the upper has been secured in place, as shown in Figure 1, is used to construct a mould core, one face of this core being made from the bottom or sole face of the shoe. The opposite face of the core is preferably, though not necessarily shaped to provide a combined sole and heel.

The core which is indicated at 10, has its inner face 11 shaped to provide a centrally raised portion 12 and a depressed marginal portion 13, the former being made by the sole face 15 of the shoe and the latter by the inturned edges 16 of the upper. As the member is cut as at 17 so that its inturned flange 16 will lie substantially flat, the space provided by these cuts form marginal raised portions or lugs 18, as shown in Figure 2 of the drawings. The bottom face of the core is illustrated in Figure 3 and includes the tread face 19 of the sole and the heel 20.

While it is preferred to form the sole and illustrated in Figure 4 of the drawings and I may be made of any suitable material. The member 21 of the mould is thus formed with a centrally depressed portion 23 which conforms to the irregularities and surface of the bottom or sole face 15 of the shoe, while a depressed marginal edge 24 is also provided to receive the inturned edges 16 of the shoe upper. Marginal depressed portions 25 extend inward from the marginal portion 24 The other mould member 22 is shaped to provide a proper thickness of sole and heel as indicated at 26 and 27 respectively.

The shoe sole which is indicated at 28 is formed within this mould, the member 21 forming a centrally raised portion 29, :1 marginal depressed portion 30 and projecting portions or lugs 31. The centrally raised portion 29 will thus occupy the space between the inturned edges 16 of the shoe upper, while the marginal depressed portions 30 will receive this edge, with the projecting portionsv or lugs 31 occupying the spaces provided by the cut away portions 17 of the upper flan e 16.

The sole may e secured to the shoe in any suitable or desired manner and when so secured, Will provide a perfect fit between its inner face and the sole face, and in addition to its many other advantages, will act to retard the passage of moisture between the sole and shoe.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is:

1. The herein described process of making shoe soles consisting of forming a core, one face of which is formed by the sole face of the shoe after-the edges of the upper have been turned inward and attached; making 'a mould from saidcore and then moulding the sole therein, so that the contacting faces of the shoe and sole will provide perfect engagement.

2. The herein describedprocess of making shoe soles consisting of using the sole face of a shoe after the edges of the upper have been turned inward and secured, for the purpose of forming a mould and of then moulding the sole therein, so that. the contacting faces of the shoe and sole will provide perfect engagement.
