Dec. 418, 1951 J. H. EVERSTON SHOE WITH A PADDED REAR PORTION Filed Nov. 23. 1948 'Y Snvenor Jose-PH H. EVg/esmv (ttornegs Patented Dec. 18, 1951 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a shoe with a padded rear portion.

The invention has particular application to a shoe for babies. It has heretofore been proposed to make such shoes by flanging outwardly the rear margins of the quarters and sewing thereto an upward extension of the sole. This forms ridges which, since infants ordinarily sit upon the floor, are apt to irritate the back of an infants foot.

It is a primary object of the present invention to eliminate the ridges and the recess which causes the ridges, as well as to provide ease and comfort to the wearer of such shoe by padding the shoe with an elastic insert in a portion of the shoe which has never heretofore been cushioned. l

By means of the invention hereinafter disclosed, I seek to provide a smooth back for the shoe and protection to the heel of the wearer against irritation, bumps and abrasions. A still further objective is to provide a construction in which the cushion may penetrate perforations to be exposed at the interior of the shoe and to act as a yieldable grip to keep the shoe from slipping at the rear. In this respect, the invention has important advantages in shoes other than shoes for babies. It is, however, exemplied in an infants shoe as disclosed in the accompanying drawings, in which Fig. 1 is a View in perspective showing a completed shoe embodying the invention.

Fig. 2 is a view in perspective showing the relatively separated component parts used to provide and secure the cushion.

Fig. 3 is a view in perspective showing a molded outsole and the lasted upper and insole cushion assembly to which the outsole is applicable.

Fig. 4 is a fragmentary detail View of the rear portion of the completed shoe in transverse section.

Fig. 5 is a greatly enlarged detail of Fig. 4.

Fig. 6 is a fragmentary detail view of the rear portion of a modified embodiment of the shoe in vertical section.

All portions of the shoe upper generically designated by reference character 1, including the

quarters

8 and 9, have marginal portions flanged outwardly at Ill for connection with the outsole II and the upwardly turned extension I2 which is integral with the outsole at the rear of the shoe.

Before the outsole is applied, the upper is completed by connecting the out-turned flange Ill with an insole I5 and with the upwardly extending tongue I6 at the rear end thereof. This tongue is preferably prefabricated to mold therein a channel Il. Throughout at least a portion of this channel, and preferably throughout the entire height of the extension I6, the leather is provided with perforations I8. Inserted in the channel is a cushion 2li which may conveniently be made of sponge rubber in dimensions compementary to those of the channel, the cushion tapering to no thickness at the point where the channel runs out, near the bottom of the shoe (or optionally beneath the heel) (see Figs. 2 and 6).

It is, of course, not essential that the extension I6 be integral with insole I5 but it is convenient to make these parts in one piece and it is appropriate to do so, since the insole is usually made of soft and flexible leather or other material well adapted, in the extension I6, to serve as a part of the upper in connecting the quarters and to make the softness of cushion 2U fully apparent to the wearer of the shoe.

The cushion may be fastened to the insole extension IE by cement 2| (Fig. 5) or in any other desired manner, this assembly preferably being complete, for the insole and the upper are connected together. The margins of the insole I5 and its upward extension I'6 are then connected to the outward flange I Il to close the upper at the rear, preferably by means of a row of stitching indicated at 22 in Figs. 1, 3 and 4, or in any other desired manner. The last (not shown) will then ordinarily be slipped into the upper, and the outsole II will nally be applied to complete the shoe. It may be connected with the insole and insole extension and the upper by a second row of stitching, as shown at 23, or in any other desired manner. Both rows of stitching shown at 22 and 23 commence at the top rear of the upper and are continuous down the back of the shoe and around the perimeter of its sole and up the back of the shoe at the other side to the top of the upper.

It will be apparent that the well which has heretofore been present in shoes of this type is completely eliminated by the cushion, and it is no longer possible for the wearers foot to engage the ridges formed by the connection of the quarters with the sole extension. Moreover, since the dimensions of the cushion 2U are preferably such that the application of the outsole extension I2 subjects the cushion to pressure, portions of the cushion are caused to project at 24 (Figs. 4 and 5) through the apertures I8 of insole extension I1, the projecting rubber protuberances 24 constituting a means which engages the foot or hosiery of the wearer to preclude relative slipping between the foot and the shoe, thus eliminating one common source of abrasion.

In my improved shoe, the sole extensions, and particularly the outsole extension I2, provide a back stay of considerable relative rigidity, which contributes materially to the support of the ankle of the wearer of the shoe. Yet, notwithstanding that relatvielt heavy back stay support is provided, thecushion protects even the most sensitive foot and enables the back stay to perform its function without discomfort to the wearer.

I claim:

1. In a shoe, the combination with an upper comprising quarters having spaced outwardly flanged margins, of an outsole having an upwardly projecting back stay extension marginally connected with the quarter flanges at the rear of the shoe, a flexible member substantially the height oi said'extension and connectedwith such flanges infront of said extension and extending forwardly within the quarters `from such connection and having its intermediate portion spaced forwardly from sai-d extension, land a cushion of a vsubstance which is materially compressible re- Siliently, saidv cushion being conned between said flexible member and said'extensicn, and substantially filling the space between said flanges-adjacent saidextension.

2. -As a new article of manufacture, an insole provided with an extension of such lengthas to project upwardly substantially to the top of the rear of the shoe in which the insole is used, the said extension having an intermediate portion disposed to lie transversely of such a shoe, and integral lateral portions extending rearwardly from the intermediate portion and joined therewith on vertical fold lines to lie at opposite sides of the shoe and flanges extending outwardly from, and integrally connected on vertical fold lilies with said lateral portions, said several portions forming 'a vrearwardly directed channel.

3. The -sub-combination set v'forth in claim 2 in which an elongated cushion of a materially compressible substance lls the channel and is unitarilyconnected therewith.
