SHOE.

SPECIFICATION forming part of Letters Patent No. 502,973, dated August 8, 1893.

Application filed June 9, 1893- Serial No. 477,045. (No model.)

To all whom it may concern: 7

Be it known that I, FRANCIS J 0s KING, a citizen of the United States, residing at Baltimore,in the State of Maryland, have invented certain new and useful Improvements in Boots and Shoes, of which the following is a specification. V

My invention relates to an improvementin shoes, and has for its object to provide means for preventing the natural moisture of the foot from inj uriously affecting the leather of the shoe-upper and at the same time provide the shoe with an absorbent for such moistnre-also to provide means to prevent water leaking from the outside into the shoe.

In the drawings, Figure 1, is a perspective view of a shoe constructed in accordance with my invention and showing the toe cut oif to exhibit the construction of the upper and the sole. Fig. 2, is a cross-section through the toe-part of the shoe. Fig. 3, is a plan view of the permeable insole.

Referring to the drawings theletter, A, represents the usual leather upper having the impervious lining, B, formed preferably of cloth saturated with a solution of india-rubber or of some other material impervious to the action of moisture. The usual cloth lining, C, of drilling or other material lies inside of the impervious lining. Said impervious lining extends entirely over the foot and as far up as the foot has a close contact with the shoe. The three layers, to witz-the leather upper, the impervious lining, and the cloth lining,

all extend down and are secured at their lower edges between the insole, D, and the welt, 01. Outside the inner sole is the usual outer sole, E, and the cork layer, F, lies between the inner am t e outer so'eslying next the inner sole.

In welted shoes, such as herein described, and shownin the accompanying drawings, the insole must be made of leather sufficiently heavy and stiff to hold in place the upper of the shoe which is sewed to it:but leather which is sufficiently heavy for this purposeis not permeable and will not permit the moist ure of the foot to pass through and be absorbed by the cork layer, F. To obviate this difficulty, I provide the entire area of the inner sole with perforations, d, extending eutirely throiigh the said insole, whereby direct communication is afforded between the inside of the shoe and the cork layer, and the moisture of the foot can be readily absorbed by the cork-layer. An impervious layer, G, lies between the outer sole and the cork layer, to prevent any moisture leaking from the outside into the shoe.

The advantages of my shoe as above described are apparent;water cannot leak into the shoe from the outside, and the moisture exuded by the foot cannot come into contact with the leather upper of the shoe. The latter is an important feature, because the said moisture is acidulated and continually acting on the leather upper of the shoe, finally disintegrates it causing it to crack and become worthless. To get rid of the said moisture, the insole is made permeable as above described, whereby said moisture passing through the permeable insole, is absorbed by the cork-layer.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A shoe comprising an upper of leather; a water-proof lining adjoining the upper and covering the foot; an outer sole, E; a cork layer, F; a layer of water-proof material G, between the outer sole and the cork-layer; a leather inner-sole, D, attached to the upper and having its lower surface in contact with the upper surface of the cork-layer, and provided with a number of perforations, d, so that moisture from the foot will pass through said perforations and be absorbed by the cork layer, as described.

In testimony whereof Iaflix my signature in the presence of two witnesses.

FRANCIS J OS KING.
