ToraZZ whom t may concern.'
Be it known that I DE Bor Aus'rm, a citizen of the United tates, and a resident of Omaha, in the county of Douglas and State 'of Nebraska, have invented certain new and useful Improvements in Shoes, of which the following is a specification.
My invention relates to the manufacture of boots and shoes, more particularly to insole cushioning structures.
It is the object of my invention to provide in a shoe a cushioning filler disposed between the insole andthe outsole and not directly attached to either so that in the bending of the sole relative movement may occur both between the insole and the ller and between the filler and the outsole.
A further object of my invention is to provide means for preventing the fibrous resilient sheet which forms the main body of the fillerfrom being dis laced from those points where it receives t e greatest pressure from the foot.'
A still further object of my invention is to provide means for preventing wetting of the fibrous filler by moisture which may pass through the outsole.
In the accompanying drawings Figure 1 is a partial side view and partial longitudinal vertical sectional view of a shoe constructed in accordance with my invention, Fig. 2 is a bottom view of the shoe with various portions of the outsole and ller brokeny away to show the underlying parts, and Fi 3 isa transverse vertical sectional view o the shoe.
In carrying out my invention I employ an upper l, welt 2, outsole 3, and insole li, all of ordinary material, structure and arrangement; the welt, upper and insole being 'secured together by the inseam 5, and the welt and outsole being secured together b the outseam 6 in the ordinary manner. here is also the usual stiifening piece 7 disposed in the shank portion of the sole. Between the insole and outsole, instead of the usual aste filler consisting of ground cork or iiair-felt incorporated with an adhesive substance, I emplo as a filler a sheet 8 of tibrous resilient materlal such as felt, which is disposed below the insole in front of the shank portion thereof and beneath theball and toe portions of the same. The thickness of the filler sheet 8 is such as to cause a very appreciable vcuslnioning eect, especially when i the insole is made of pliable leather or where the leather is speciall treated or in* cised so as to render 1t exi le. Below the felt sheet 8 is' placed a relatively thin sheet 9 of Hexible non-resilienty material such as leather-board which is practically waterproof or impervious to moisture. 'Ihe sheet 9 is extended back into and secured in the shank above the stiHening-piece 7 and the latter may be secured to the sheet by a rivet 10. rIhe ller sheet 8 is secured to the sheet 9 by suitable means such as the longitudinal seam 11 indicated in Figs. 2 and 3, or by pasting or cementing the sheets together.
Under the bell and toe portion where the sole bends in walking, a thin layerl 12 Vof a suitable filling material is placed between the sheet 9 and the outsole. 'Ihe said filling material is preferably non-adhesive and may be in the nature of a lubricant to prevent squeaking of the shoe due to rubbing of the adjoining surfaces when the sole is bent.
'Ihe sheet of leather-board 9, being comparatively rigid inthe plane of the sheet and being secured to the felt sheet 8, tends to prevent the lat-ter from working out and -becoming thinned at the parts thereof which receivethe greatest ressure from the foot. rIhe ller as a who e being unattached to either the outsole or the insole, when the sole is bent there may be relative movement between vthe insole and iller and between the filler and outsole, so that the exibility of the sole as a whole is increased. The leather-board Aalso serves to prevent the filler-sheetS being wetted by moisture penetrating the outsole.
Now, having described my invention, what I claim and desire to secure by Letters Patent is: Y
l. In a shoe having an outsole and insole, a filler disposed between the outsole and insole and comprising a sheet of fibrous resilient material adjoining the insole, and a sheet of iirm non-resilient material disposed below and secured to the sheet of resilient material, the filler being unattached to either the outn sole or the insole. v
2. In a shoe having an outsole and insole, a filler disposed between the outsole and insole and comprising an upper sheet of fibrous resilient material, a sheet of non-resilient moisture-proof material disposed below the sheet of fibrous resilient material, and means for securing said sheets to each other, the fibrous sheet being unattached to and free to move relatively to the insole.
3. In a shoe having an outsole and an insole, a filler disposed between the outsole and insole and comprising a sheet of fibrous resilient material disposed adjoining the insole beneath the ball and toe portions thereof, and a sheet of moisture-proof material secured upon the lower side of the resilient sheet and extending between the shank portions of theoutsole and insole, the fibrous sheet being unattached to the insole.
4. In a shoe having an outsole and an insole, a filler disposed between the outsole and insole and comprising a sheet of fibrous resilient material disposed beneath the ball and toe portions of the insole, a sheet of relatively firm material disposed below said resilient sheet and extending between. the
shank portions 'of the insole and outsole,
means for securing said sheets to each other, and a layer of non-adhesive material between the lower sheet and the outsole.
5. In a shoe having an outsole and an in? sole, a sheet of fibrous resilient material disshank portions of the insole and outsole, and
means for securing said sheets together.
6. In a shoe having an outsole and an insole, a sheet of felt disposed beneath the ball and toe portions of the insole andunattaohed thereto, a sheet of leather-board disposed beneath the felt sheet and extending between the shank portions of the insole and outsole, a seam securing together the sheets of felt and leather-board, and a layer of non-adhesive' material disposed between the sheet of leather-board and the outsole to permit relative movement thereof and prevent their adjoining surfaces rubbing together.
In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
