4117 01175 Ben A ttorney Patented Ma 12, 1931 ANTONIO JANDOC AND BEN .A. LAGMAY, OF WILMETTE, ILLINOIS VENTILATED SHOE Application filed September 26,1829. Serial No. 395,340. g
This invention relates to a shoe and has for its prime object to provide means for ventilating the interior of the shoe.
Another very important object of the in.-
vention resides in the provision of a vcitiiating device of this nature which isexceedingly simple in construction, inexpensive to manufacture, easy to install, strong and durable, not likely to easily become out of order,
thoroughly efficient and reliable in use and operation and otherwise well adapted to the purpose for which it is designed.
lVith the above and numerous other obiects in view as will appear as the descrip- 16 tion proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing:
Figure 1 is a bottom plan view of the shoe embodying the features of my invention,
Figure 2 is a side elevation partly in section of the shoe showing our improved 2 ventilating device,
Figure 3 is a bottom plan view of the ventilating device showing portions in section,
Figure i is a sectional view taken substantially on the line H of Figure 5 through the diaphragm of the Ventilating device, and
Figure 5 is a sectional view taken substantially on the line 5-5 of Figure l of the ventilating device.
Referring to the drawing in detail it will be seen that the numeral 5 denotes the sole of a shoe that is the outer sole thereof and the numeral 6 the inner sole thereof. On the bridge or instep portion of the sole 5 .40 there is mounted a diaphragm 7, the bottom of which is provided with prongs 8 to bite into the sole 5. The inner sole 6 is placed over this diaphragm.
The diaphragm 7 has a coil spring 9 in the center thereof to assist the same in normally being expanded. A radial conduit 10 is formed in the lower wall of the diaphragm radiating outwardly from the center thereof and terminating at its outer end in a hollow cross head 11 to the ends of which are attached check valves 12 and 14 which open forwardly.
A'conduit 15 is engaged with the check valve. 12 and extends forwardly terminating to exhaust in-the tip of the shoe while a conduit 16 is engaged'with the check valve 14 to extend rearwardly and upwardly as is indicated to advantage in Figure 2.
From the above detailed description it will be seen that when the shoe is used in walking, the foot will exert pressure on the diaphragm so as to force air out through the conduit 10, forwardly through the check valves, and the conduit 15, to ventilate the interior of the front end of the shoe and as the diaphragm expands with the assistance of its spring 9, air will be sucked thereinto through the conduit 10, the check valve 1% and the conduit 16.
From the above detailed description it will be seen that this invention provides the shoe with means for changing and refreshing the air therein while being worn.
This refreshing of the air provides comfort for the feet and would greatly assist in eliminating ills and sores common to the feet.
It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.
The present embodiment of the inven tion has been described in considerable detail merely for the purposes of exemplifiestion since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It will be apparent that changes in the details of construction may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing. any of its advantages.
Having thus described our invention, what we claim as new is:
1. A ventilating device for shoes comprising a compressible bulb for disposition within the shoe above the heel portion thereof, a conduit extending from the central portion of the bulb toward one side of the shoe, a hollow cross member at the free end of the conduit, inlet and outlet valves at opposite ends of the said cross member, and a tube extending from the outlet end of the cross member toward the toe portion of the shoe.
2. A ventilating device for shoes comprising a compressible bulb for disposition within the shoe adjacent the heel portion thereof, a conduit extending from the bulb toward one side of the shoe, a hollow cross member at the outer end of the conduit, inlet and outlet valves at opposite ends of said cross member, and a tube extending from the outlet end ofthe cross member to a point adj-2v cent the toe portion of the shoe.
In testimony whereof we aflix our signatures.
