Application led February 21, 1916. Serial No. 79,766.

leading downwardly from inlet openings at v or near the top of the boot leg or the shoe upper and havin inwardly perforated extensions continumg horizontally and externally around and over the sides and frontV of the foot, inqicombination with a similar but inwardly perforated independent air passage or passages leading downwardly from said inlet openings and terminating at the heel, thereby insuring an ample supply of air to all parts of the foot or leg and foot as the case may be.Y

My invention further consists in the combination, with said air inlets and perforated and unperforated external air passages, of a grooved recessed-and perforated insole device whereby. the natural movement of the foot within the boot or shoe is utilized to induce a double suction or pumping action and vmaintain a more or less constant-circulation of air throughout the air passages, which air circulation is distributed, by way of the various perforations, over around and under the foot of the wearelgand alsoy down vthe leg when required. l

My invention,though of general application to all types of boot and shoe (either leather, rubber, or canvas), is more especially applicable to waterproof boots such as sea boots, military top boots, trench boots, riding boots, and the like. A comfortable and hygienic boot or shoe is produced, which will be found of great utility in hot countries, and especially at sea.

My said invention is illustrated by way of example in the accompanying drawings, in

lwhich:--

Figure 1 is Ia side elevation of a ventilated rubber top boot having side inlet passages;

Fig. 2 is a plan-of Fig. 1, in section on the line aa; Fig. 3 is a side elevation of a ventilated rubber top boot having rear inlet passages; Fig. 4 is 'a plan of Fig. 3, insection on the line bb Fig. 5 is a plan (inverted) of the auxiliary insole device; Fig. 6 is a side view of Fig. 5; Fig. 7 is a cross-section on the line cc of Fig. 5.

According to my said invention I provide a series of narrow strips A which are applied externally to the boot or shoe in such a manner as to form a series of approximately parallel air passages B leading downwardly from inlet openings C at or near the top of the boot leg or the shoe upper and extending horizontally over and around the sides and front .of the foot. These strips A and air passages B are inclosed within a cover D, which is comparatively narrow in width and is likewise extended around the sides and front of the `boot or shoe in the form of a brogue or wing cap. In the case of a waterproof rubber boot the strips A are preferably of rubber, the strips and cover being secured externally in position by cementing and vulcanizing under pressure; in the case of a leather or canvas boot or shoe the strips A may be of' leather, canvas, whalebone, or other `convenient material, the strips and cover being secured externally in any convenient manner, but referably by stitching. The inlet openings and the air passages leading therefrom may be arranged at both sides of the boot or shoe (as shown in Figs.

1 and 2), or they may be arranged at the' -thus preventing any possibility of the air supply being intercepted and tapped before reaching the foot.

Short intermediate strips F may be provided at suitable points if found necessary to prevent sagging of the cover D. Provision may be made, especially in the`V Case of waterproof top boots, for protecting the inlet openings C against ingress of storm water, a projecting rim G being suiicient for this purpose, or an adjustable flap; but in the case of ordinary walking boots and shoes this protecting device` may be dispensed with. rIhe strips A may be reinforced by wire or otherwise if desired, and the cover `D may likewise be reinforced by metal or other strips or plates at any desired point or points. v

In combination with the air inlets and perforated and unperforated external air passages as hereinbefore described, I provide a loose perforated insole H of leather,

cork, rubber, or like material, or of such the foot of thel wearer, and also .down the' leg when required.

My improved ventilated boot or shoe can be constructed at aA comparatively low cost, and the improved Ventilating device can also be readily and cheaply applied to existing boots or shoes.

My invention prevents or minimizes the trouble hitherto due to frosty feet in cold weather, and sweaty feet in hot climates.

I claim 1. In aboot or shoe, in combination, a series of parallel iexible separated strips applied externally down the leg, extensions of sundry of said external strips continuing horizontally around and over the sides and front of the foot, and a comparatively narrow external cover inclosing the whole of said separated external strips in such a manner as to form a corresponding series of external air passages open adjacent the top of the leg, sundry of said external air passages being unperforated down their leg portions but inwardly perforated throughout their horizontal extensions around and over the sides and front of the foot, and the remainder of said external air passages being inwardly perforated down the leg and terminating at the heel. i

2. In a boot or shoe, a series of parallel flexible separated strips applied externally down the leg, extensions of sundry of said external strips continuing horizontally around and over the sides and front of the fo0t,-and a comparatively narrow external cover inclosing the whole of said separated external strips in such a manner as `to form Y,

a corresponding series of external air passages open adjacent the top of the leg, sundry of said external air passages being unperforated down their leg portions but inwardly perforated throughout their -horizontal extensions around and over the sides and to thereby maintain a constant circula- 75 tion of air throughout the air passages and perforations.
