SHOE.

Specification of Letters Patent.

Patented May 24, 1921.

Application led May 27, 1918. Serial No. 236,837.

To all whom it may concern:

Be it Vknown that I, MEYER S. Hnss, a citizen of the United States of America, residing at Baltimore city, in the State of Maryland, have invented new and useful improvements in' Shoes, of which the following is a speci ication. l

The purpose of the invention is to vprovide a new and useful construction for shoes in the form of a composite insole whereby the usual insole is employed but becomes a subsole in the improved construction and has superimposed upon it a supplemental insole orY what is known throughout this construction as a super-sole. In the improved construction there is employed the common way of forming the sub-sole with its marginal rib for' the purpose of securing the welt thereto andthe feather left by the forming of this rib serves as a means for the attachment of the super-sole which is channeled in a new and novel way to provide a margin'al feather for interlocking connection with the feather formed on the sub-sole. This particular construction provides for the use of the ordinary leather insole or the cheap paper insole, either one of which is reinforced and made relatively thick and substantial' when the improved super-sole is attached. The super-sole is made preferably of a chemically treated felt material having waterproofing qualities, flexibility and comparatively great wearing qualities. It takes the place ofthe sock lining employed to cover the usual insole and all told greatly simplifies the construction and reduces the cost of production of the shoe in which itis used, aside from providing the other advantageous features referred to above. v In the drawings which accompany this specification and form a part thereof: i' Figure l is Aan elevational view of :a shoe employing the improved insole, the upper and'outer sole being broken away so as to show the improved insole in longitudinal edge elevation.

Fig. 2 is a transverse sectional view taken in the vicinity of that part of the insole on which the ball of the foot rests.

Fig. 3 is a detail sectional view of the improved insole taken in a longitudinal direction from the point of the toe to a point just back of the toe. This for the purpose of showing the means for securing the supersole to the sub-sole when the shoe construction is of a pointed toe style.

Fig. 4 is a detail sectional view vshowing how the super-sole is cut to provide means for attaching it to the sub-sole.

Fig. 5 is a detail sectional view showing how the sub-sole is channeled or cut to provide its marginal rib and feather.

Fig. 6 is a detail bottom plan view showing the securing strip for the toe of the super-sole when the composite insole is used with a pointed toe shoe.

To illustrate the invention, there are shown thel usual shoe elements consisting of the upper 1, theJ outer sole 2 and the welt 3. With these elements there is associated the improved composite insole consisting of the sub-sole 4 and the super-sole 5. The subsole is provided with the usual marginal rib 6 formed by means of a channeling machine which cuts webs of material from the body of the said sub-sole. These webs are turned down to a position substantially perpendicular tothe surface of the said sole and thereby leave a marginal feather 7 tapering in thickness away from the said rib, so that the thinnest portion of the feather is at the extreme edge of the said sub-sole.

rThe super-sole 5 is attached on top of the sub-sole 4 and this super-sole is cut to agree in plan dimensions with the dimensions of the shoe with which the improved composite solo is to be used. On its under face the super-sole is channeled adjacent to its marginal edge so as to leave a feather 8, the channeling being done in a direction toward the marginal edge in order that the said feather 8 may be joined with the super-sole at the marginal edge and be directed inwardly therefrom. rlhis channeling is done to within one-eighth or one-sixteenth of an inch of the extreme edge of the super-sole, thereby leaving the one-eighth or one-sixteenth inch thickness of stock to serve as a within one-eighth of an inch of the edge of the .super-sole, the plan dimensions of the sub-sole are reduced by this amount.

The feather 8 having been formed on the bottom face of the super-sole, this feather is thrown back and the sub-sole is placed against the under face of the super-sole with its top face against the under face of the latter. Then this feather 8 is brought up against the under face of the feather 7 to which it is secured by any suitable means, preferably cement, and thenturned down .against the outer face of the rib 6.

The sub-sole l is so prepared that fthe rib 6 terminates at the beginning of the heel portion 9 of the sub-sole and the equivalent portion 10 of the super-sole lies on top of this heel portion. 9 to which it may be secured by cement or other suitable means, the interlocking feathers being omitted in the heel portion of both elements of the composite insole.

If the shoe constructed in accordance with this invention be of the broad toe style, the marginal feather 8 is extended around the toe, since a channeling machine may be operated to provide the continuous formation of this feather beginning at the heel on. one side and extending continuouslyaround the toe to the beginning of the heel on the other side. If, however, the shoe being constructed has a toe of the pointed style, the feather 8 cannot be made -continuous because of the impracticability of carrying the channeling around the apex of the toe.

By referring to Fig. 3 it will be readily seen how the improved super-sole Vis attached to the sub-sole at the toe when theV latter is pointed. A strip 11 is employed and secured adjacent lto the marginal edge of the pointed ltoe of |the super-sole 5 by a line of stitching 12. This strip is then made to embrace the feather 7 and the rib 6 on either side of the apex of the toe and is securedto both the inner and outer face of the rib by cementor any other suitable means.

The co-mposite insole having been prepared in the manner above described, ythe welt 3 is secured by a line of stitching 14 to' the marginal rib 6, ,as is usual' in shoe construction, but the feather 8 of the supersole is interposed between the welt and the rib and the stitching 14 serves to secure this feather `and further it serves to secure the sub-sole fto the welt by engaging its marginal rib 6. Ofcourse the upper 1 is secured to the welt and to the composite sole by the stitching 14 .and its position relative to those parts is the same as is common in shoe construction.

That the outer sole 2 may be secured t0 the welt, 'the line ofstiltching 15 is employed, this, of course, being one of the usual means for attaching the outer sole to the vamp.

It will be observed that the improved composite insole provides for the obtaining of a relatively thick and substantial insole and thereby the obtaining of a relatively strong and substantial'shoe with the use of an inexpensive sub-sole which, by itself, is

Vof insufhcient strength to stand the strains or retain its shape. Leather of thickness and quality for use as insoles as hereto-V fore constructed being very scarce and expensive, the improved construction described above furnishes a substitute insole which has the desired thickness, strength and flexibility .and has the further advantages of ybeing practically moisture, heat and cold proof, has a. noncurling feather, and presents a smooth and comparatively soft surface to the foot.

lVhile theinvention has been dened as a composite insole consisting of a leather sub-sole and 'a' super-sole super-imposed thereon, it is obvious 'that the composite insole may comprise a lsub-:sole made of cheap material, such las pasteboard or materials possessing similar characteristics. While it' is intended that the super-sole shall be made of a specially prepared chemically treated felt material, it is apparent that any other material serviceable as a supersole may be employed without departing from fthe spiri-t or sacricing any of 'the advantages of the invention. i
