CHARLES KOCH, OF BROOKLYN, NEW YORK.
Specification of Letters Patent.
Application filed. March 23, 1909.
Patented Feb. 22, 1910.
Serial No. 485,277.
To all whom it may concern:
Be it known that I, CHARLES KOCH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Shoe-Ventilators, of which the following is a specification.
This invention relates to shoes and more particularly to ventilating means for same which may be attached as a tongue or foot pad or any other desired adjunct for a shoe and consists of tubes of rubber or similar material held between layers of leather or fabric to admit air within the shoe, as will be more fully explained in the following specification, set forth in the claim and illustrated in the drawings, where:
Figure 1 is a perspective view of a shoe with the improved ventilator applied thereto as a tongue. Fig. 2 is a plan View of the tongue. Fig. 3 is a cross sectional view.
The invention is preferably applied to tongues of shoes as shown in Fig. 1 of the drawing and may be so used to not only ventilate the shoe but to also relieve the shoe of tightness or strain over the instep after it is buttoned or laced. When used as a tongue it is made up of two wedge shaped pieces of leather 5 and G inclosing the rubber tubes 7, arranged at a tapering or inclined relation in respect to one another, said tubes being open at both ends whereby the air may freely pass through them, and the tongue is attached by means of its smaller end S to the inside of the shoe at the point where it is usual to secure the tongue. After inclosing the tubes the two pieces of leather are stitched together along the sides of the tubes so as to firmly grasp them and prevent their being removed, thereby securing the several parts together in a rigid position in respect to one another. The movement of the instep forces the air in and outof the tubes which may be made of suiiicient rigidity to resist being closed by the lacing but flexible enough to bend with the instep.
lVhat I claim as new and desire to secure by Letters Patent is:
A. shoe ventilator in the form of a tongue, comprising two wedge'shaped pieces or flexible strips, flexible tubes located between said strips and arranged at a tapering or inclined position along the entire length of the tongue thus formed, the ends of said tubes terminating at the opposite ends of the tongue and on a line with one another and with the ends of the tongue, and means for securing the several parts together and in a rigid position in respect to one another.
Tn testimony whereof I atlix my signature in presence of two witnesses.
