Specification of Letters Patent. Pat nted Nov. 28, 1911.
Application filed March 21, 1911. Serial No; 615,945.
To cit whom it may concern:
Be it known that I, OSCAR STERN, a subject of e the German Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shoes, of which the following is a specification.
The object 'of my invention is to provide a shoe or like foot wear with ventilation means, so that there may be a continuous supply of fresh air in the foot wear while in use.
To accomplish this, my invention consists in the construction, arrangement and combination of parts as hereinafter specified.
.In the accompanying rdrawlng, similar reference numerals denote correspondingparts and Figure 1 is a vertical section through a shoe equipped with my ventilation means; Fig.2 is an inner plan view of the heel portion of my device; Fig. 3 an inner plan view of the sole and toe portions thereof; Fig. 4 is a cross section on line 44 of Fig. 2; Fig. 5 is a cross section on line 55 of Fig. 1; Fig. 6 is a cross section on line 6-6 of Fig. 2; Fig. 7 is a cross section on line 77 of Fig. 3 and Fig. 8 is, a longitudinal'se'ction on line 88 of Fig. 3.
p In the drawing, which forms a part of this invention, 1 denotes a shoe, 2 the'sole and 3 the heel thereof. A pad 4 of rubber, cork or the like is glued or otherwise fastened to the inner surface of the sole, to cover the latter to about the front end of the arch 5' of the sole. The lateral and front edges of the pad are shaped in conformity with those bf the sole and on its upper face is formed iwith a great number of hollow spherical projections 6. I form the spherical projections with apertures 7 to render them more elastic. Transversely the pad maybe somewhat curved (see Fig. 7) in conformity with the inner surface of the sole of the shoe.
Extending from and somewhat overlapping the inner end of the pad is a member 8, which is adapted to bear on the inner surface of the arch portion 5 of the shoe, and
the circumference of which is shaped in conformity therewith. This member, which I prefer to make of metal, is longitudinally corrugated to form passages or flues 9 and at the rear end formed with an even tail portion 11, the tines being slitted at this tail portion as at 12. Theportions forming the fines are (perforated as at 10. The tail portion is a apted to bear on the forward end of the inner surface of the heel 3. A pad 13 shaped in conformity with the inner surface of the heel and also somewhat curved transversely (Fig. 4) is adapted to bear on the inner surface of the heel overlapping the ,rear or tail end of the arch member 8 (Figs.
1 and 2). This pad, as the sole or toe pad, is preferably formed of rubber, but cork or other suitable material may be used for it, and is formed on its upper face with similar hollow projections 14 formed with apertures 14 as the former. Said projections may, however, be somewhat higher than'those of the sole pad 4. This pad is likewise glued or otherwise suitably fastenedto the inner surface of the heel.
Extending over the pad 13, arch member 8 and pad4 is the insole 15, of leather orother suitable material, and which is perforated on its entire surface as at 16 (Fig. 1). The heel 3 is provided with a chamber 17 opening at the top and communicating with the flues 9 through the slitted ends 12 of'the latter. In the front-surface of the heel an opening 18 is provided which communicates with the chamber 17 of the heel and in which a suitable valve 19 is arranged permitting the closure of said opening 18. In the example shown, a slide block or plate is used as a valve, which is guided in suitable guides-20.
The operation of this device is as'follows: When the valve 19 controlling the opening 18 is open the air contained in the shoe will be expelled as the wearer in Walking compresses the elastic projections of the pads 4 and 13. The air will pass through the fines 9 into the chamber 17 and thence through the opening 18 into the atmosphere. On the other hand, as the wearer in walking lifts the toe portion or heel portion of his foot, the rai'efication of the air caused by the pre vious expulsion, will now produce a suction action, fresh air being drawn into the shoe through the opening 18 into the chamber 17 and thence through the flues 9 and perforations 10 thereof into the spaces between the pads 4, 13 and arch portion 8 and the insole 15. Through the perforations 16 of the latter, the fresh air will be permitted to enter into the upper portion of the shoe and cool the foot.
It is, of course, understood that various modifications made he made without deviating from the Spirit. of my invention.
, What I claim and desire to secure by Letters Patent is: V
In a shoe or boot, a flexible pad having hollow-spherical projections and fixed to the inner surfaces of the sole, a corrugated perforated member over the arch portion of the shoe, the corrugations of which form flues, a heel formed with an open topped chamber having an opening leading into the atmosphere, a flexible pad having hollow spherical projections covering the said chamber, a perforated insole extending over 5 the said 'flexible pads and the arch member and resting on the said spherical projections, and a. slide valve leading into the said chamber.
In testimon whereof I afiix my signature 20 in presence 0 two witnesses.
