3 Claims.

The present invention relates t shoe construction and more particularly 4to improvements in womens shoes and the heels thereof.

Although the invention may apply to different types of shoes, it is of particular value in connection with the manufacture and use of shoes in which the sole and the heel are secured in position in the shoe by the use of adhesive material such as a suitable cement. Heretofore it has been a common practice to manufacture womens shoes of this general type by placing an upper and an insole on a last, drawing the edge of the upper around the edge of the insole and securing the upper material in position on the bottom of the insole by means of a suitable adhesive, except at the heel where the upper is secured to the insole by driving therethrough tacks which may be clinched by driving them against a metal plate on the last. Then there may be attached to the bottom surface of the insole and the edge portions of the upper, a heel and an outsole having at its rear end a heel breast flap to be secured in position on the breast of the heel after attachment of the heel and the main outsole to the insole. The fastening together of these two parts may be effected by use of a suitable adhesive such as cement. The heels may be of the Louis type. One of the principal objections to shoes of this type heretofore in use is that the heels have been likely to break away from the sole at the breast of the heel.

An important object of the present invention is to provide for novel and advantageous shoe construction.

Another object of the invention is to provide for shoe construction whereby the tendency of the heel to break away from the outsole adjacent to the heel breast may be avoided.

A further object is to provide a strong connection between the heel and the shoe particularly at the breast of the heel.

According to a preferred manner of carrying out the invention, the upper and insole may be assembled on the last and the edge of the upper may be drawn around the edge of the insole and suitably secured to the lower surface thereof, that is the surface that will be down when the wearer is standing. The fastening of the edge of the upper to the bottom of the insole may be effected by adhesive at the front of the heel section and by clinched tacks at the heel. The part of the operation just described corresponds to the general practice heretofore in use. However, instead of using an outsole of the usual type having at its rear end merely a heel breast flap to be pasted to the breast of the heel, use is made of an outsole provided above the heel breast flap with a strong tab integral therewith and adapted to be secured, as by adhesive material in a corresponding recess in the breast of the heel but of less width than the breast thus providing a strong connection between the front part of the heel and the rest of the shoe structure, the heel breast flap being used as usual. Then a comparatively narrow heel piece, provided with a beveled forward edge, may be used on the heel seat, said beveled forward edge being secured to the outsole by suitable means such as an adhesive. Said heel piece may if desired be integral with the outsole. It will be evident that constructionaccording to the present invention will provide a shoe in which the heel is very strongly attached to the shoe.

Other objects, features and advantages will appear upon consideration of 4the vfollowing detailed description and of the drawing, in which:

Fig. 1 is a fragmentary vertical section taken longitudinally of the shoe;

Fig. 2 is a front elevation of the heel when separated from the other parts;

Fig. 3 is a fragmentary perspective on a larger scale of the rear end of the outsole; and

Fig. 4 is a bottom plan View of the heel piece designed to be placed between the heel and the heel seat and to have its forward end attached to the outsole.

Referring to the drawing, the invention is illustrated as applied to a shoe I0 and involves the use of a heel vl I, which may be of the Louis type except for a recess I2 in the breast i3 of the heel, and an outsole i4 which may be provided at its rear end with a usual thin heel breast ap l5 and a rearwardly extending relatively thick tab I6 adapted to fit and be secured in the recess by suitable means such as an adhesive. Satisfactory thicknesses for the various parts oi the outsole may be 8 irons for the front or thickest part, 2 irons for the heel breast flap l5 and 6 irons for the tab I6. It will be evident that a very strong connection between the outsole I4 and the heel Il may be obtained by use of the tab I6, which is of substantial thickness to give it the necessary strength. It should be noted that in Fig. 2 the heel Il, of suitable material, such as wood, is illustrated as having covering material secured thereon.

As illustrated the heel Il has a forwardly projecting lip at the forward end of the heel seat and the recess l2, which is of less width than the breast, starts at the lower side of the lip and extends from the lip a substantial distance down the rest of the breast to enable a strong connection to be eiected between the tab I6 and the heel. The space above the heel seat normally occupied by the rear end of the outsole may be Iilled by a heel piece I 'I having a beveled forward edge which may be secured at its forward end to the tab I6 or other strong part of the outsole. The heel piece Il may also be beveled at its edge around its sides and rear so that it may be seated to greater advantage on the top of the heel I I.

It will be evident that with a shoe constructed in accordance with the present invention, there will be very little danger of the heel breaking loose from the shoe at the heel breast.

It should be understood that changes may be made in various features and that certain features may be used without others, without departing from the true spirit and scope of the in- Vention.

What I claim is:

1. In a womans shoe of the class described, the combination of a heel having in its breast a recess extending from the top of the heel part way down the breast, and an outsole split at its heel portion into a heel breast ilap and a tab of greater and substantially uniform thickness receivedin said recess and secured to said heel to provide a strong connection of said heel to the rest of the shoe.

2. In a womans shoe of the class described, the combination of a heel with a forwardly projecting lip at its top and provided at its breast with a recess of less width than the breast so as to leave side portions of the breast, said recess extending along the lower face of the lip and a substantial distance down the rest of the breast, and an outsole split at its heel portion to provide a heel breast iap and a tab of substantial thickness positioned in said recess and secured to said heel to provide a strong connection between the heel and the shoe, said heel breast flap being secured to said tab and the breast including said side portions of the breast.

3. In a womans shoe of the class described, the combination of a heel with a forwardly projecting lip at its top and provided at its breast with a recess of less width than the breast leaving side portions of the breast, said recess extending along the lower face of the lip and partway down the rest of the breast, and an outsole split at its heel portion to provide a heel breast iiap and a tab of substantial strength in said recess and secured to said heel by adhesive material to provied a strong connection between the heel and the shoe, said heel breast flap being secured by adhesive material to said tab and the breast including said side portions of the breast.
