VENTILATED SHOE Filed July 10, 1947 FIG. 6.

Patented Jan. 4, 1949 UNITED STATES PATENT OFFICE 8 Claims.
This invention relates to ventilated shoes, and is herein described in some detail as embodied in a mans low shoe.
Many attempts have been made to provide bet ter ventilated shoes so that perspiration may evaporate or be carried off rapidly, and considerable success has been attained in developing leathers which might be nearly Water-proof and yet permit the rapid evaporation of perspiration. Some upper leathers have been produced which permit such evaporation through the uppers at nearly three-fourths the rate of evaporation from the bare foot, but sole structure presents a (lifierent problem.
According to the present invention, the problem of ventilating through the sole of a shoe may be completely solved.
In the most complete form herein illustrated, the sole of a shoe is formed of a bottom, which may be flat, and that bottom is stitched to the upper through an intervening resilient channelled spacing member or slip-sole provided with channels, preferably open at the edge of the sole.
In the form illustrated, the wearers foot rests on an insole consisting of plastic nettingresting on the ridges between the channels, so that the wearers foot, through the interstices of the netting, and the channels, is exposed to the outer air.
The netting, preferably, extends out to the edge of the sole so thatit formsan insole which is bound by the same stitching thatholds thesole to the upper,
The spacing member may be made of a resilient plastic. Both cellulose acetate and Plexiglas have been found satisfactory, and was highly elastic and otherwise suitable when the channels were made by spaced ribs of one of the same plastics cemented crosswise of the sole, so that,v the ribs formed the ridges for supporting the insole.
The netting insole was found eminently satisfactory when made of plastic filament eommercially sold mosquito netting having sixteen meshes to the inch, carried on fiat-topped ribs about three-sixteenths of an inch wide and spaced about the same distance apart.
That structure was comfortable for most Wearers of the shoe, and it adequately supported an extra thin felt insole, or a fairly rigid perforated sheet insole, if desired. The plastic netting may include central thread cores covered by the plastic.
The stitching which is shown holding the structure together may overlie a stiff outer welt which is rigid enough to hold down and keep in shape the edge of the vamp or upper, and the stitches 2 shown pass through the welt, the edge of the upper, the insole, the ridges and through a sheet of rubber below the fiat bottom of the slip-sole, to hold the rubber and channelled slip-sole to the upper.
Preferably, the rubber sheet is additionally cemerited to the slip-sole. Then an outer sale, which has been found satisfactory if of ordinary flexible sheet rubber sold at retail, is cemente to the first rubber sheet.
The whole makes a strong reliable comfortable shot, adequately ventilated at, the sale in all weathers, and, combined with a perforated top. or the above-mentionad ventilating upper leather, forms an almost perfect shoe for comfort and wear-resisting qualities. it i In the accompanying drawings: Fig. 1 is a side view of one form of shoe of present invention. i
Fig. 2 is an exploded sectional same. i Fig. 3 is an enlarged fragmentary section on the line 3-3 of Fig. 4.
Fig. 4 is an enlarged fragmentary side the vamp, the welt and the sole layers.
Fig. 5 is a topview of a, modified slip-sole. Fig. 6 is section on the line 6-6 of the parts shown in Fi 5. i i
The shoe shown was made by cuttingan upper vamp ill to the desired shape, with three-thirty seconds of an inch-spaced perforations H as shown, if desired, over a large part of the vamp. The inner counter l2 was stitched in at a suitable time and extended out as described below. i A sheet of suitable resilient flexible plastic l3, resistant to body heat and to moisture, was provided with cross ridges l4, spaced about 'threesixteenths of an inch apart to form channels and of about the salife width and height, by cementing suitable'bars of the plasticon one face of the sheet 13. On the opposite flat face" 15* was :laid a sheet of commercial flexible red rubber l6 about one-eighth inch thick, and cemented down to it. Then a reticulated insole H of the above described mesh was laid on the upper faces of the ridges [4. The vamp l0 and counter l2 were laid around a last (not shown), if desired, so that their outer edges lay flat on the outer edge of the cut-to-shape slip-sole l3 and insole ll. Then a stiff welt l8, beveled on its inner edge, was laid on the edge of the vamp I'll. Then the edges were stitched down by thread passing down through the center of the narrow welt l8. through the insole H, the ridges I4 and the slip-sole I3 and the rubber sheet Hi.
the
side view of the viewaof This bound the above described parts firmly together. The shoe shown was double sewed so that one up and one down thread 20, 2| passed through each hole near the end of each ridge M, along the side, and at suitable intervals at the toe and heel where thicker bars are shown.
Then the outsole 22 was cemented on the red rubber l6, and the shoe was complete, after attaching asuitable heel 23 e It wasfpossibleto' sub 'tit/ute other plastics and other flexible sheets and other insoles, but the formed of open mesh netting, a water-repellent above was satisfactory with a cellulose acetate:
Also, alternatively or additionally, shallow top" channels 26 may lie in the topsof the ridges M. If the ridges fornii'ng"channe1s ,are"of cellulose acetate oif' Plxiglasdr certain otherplastics they repel water; ea s te not ee'sny wet, me time tend to keep the feet dry even on" wet streets. The additional channels 24 and 25 may leave ridges; which take the for'rfi'of'spacedm'ounds to support'the in'sol' 'l'li V v The ridges l 4of the size and spac'ingl'described are suitable for heavy mehsjshoezs Other shoes will use smaller and narrower and'closenridge's.
