APPLICATION FILED 51111.13, 1906.

. Patented Feb. 16, 1915.



Specification ot Letters Patent.

Patented Feb. 16, 1915.

Application led January 13, 1906. Serial No. 295,978.

T0 all lwhom it may concern Be it known that I, GEORGE VALIANT, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Shoes, of which the following is the specification.

My invention relates first to a `shank curve-forming, sustaining or stifening device, second a Ventilating appliance and third, a combined Ventilating and shank curve-forming, sustaining and stiifening device; either feature being perfect in its function independent of the other, but each equally important as a separate improvement in shoe construction, hence I desire to secure claims protecting my invention in the performance of these functions separately and jointly. f

My invention also relates to improvements in ventilated shoes and the object of the invention is to provide a shank stiffener combining the utilities of stifl'ening and effectnally ventilating a shoe, and also to furnish a means by which shoes not originally designed for ventilation may be readily converted into ventilated shoes without necessitating introducing into such unventilated shoe any cumbersome Ventilating appliances, which among other disadvantages necessitate a larger shoe being worn than the wearer would otherwise require, and a further object is to obviate the necessity for the use of channels, air ductsv` springs within channels and other methods for introducing air between the soles and yet allow my Ventilating shank stiffener in case such appliances are preferred to be used with any and all of them.

My invention consists of a Ventilating shank comprising ar retaining member or members and a perforated movable portion to register with perforations through the shank of the shoe.

vFigure, l. is a perspective view of a shoe showing it reversed and partially .broken away in order to exhibit the position of my invention in the shank. Fig. 2, is an enlarged perspective detail of a portion of the shank showing my improvement. Fig. 3. is a cross section through the heel and shank and inner end of the retaining plate. Fig. 4, is a cross section through the shank and my device.

In the drawings like letters of reference indicate corresponding parts in each figure.

metal having a correslwnding number o perforations 1) arranged in a row corresponding to the per` forations B and at the same distance apart. The plate I) is provided with a knob D2 for manipulating the plate and with a curved engaging end D,

l] 1s the retaining plate, which is fastened on the step C around the recess nails or any other suitable fastening. The plate E is provided with a row of perforations 2 corresponding in number and substantially registering with the perforations B in the shank. The rear end of the plate E is provided with two alined recesses E stamped or otherwise formed up in the plate and with one of which the curved end D3 is designed to engage. The rear end of the retaining plate .ll is also provided under the heel with bent edges E2 which are designed to retain the plate in position and obviate any undue pressure on theheel binding the movable plate in position.

l" is a strip of fine wire cloth, which is located on the inside of the shank ofthe shoe and adapted to cover the perforations B.

G is the inner lining of the shoe` which is provided with a longitudinal opening G or perforations. if desired. designed to always leave the perforations B open and free except for the wire cloth. The lining (l serves to cover the edges of the wire cloth and thereby prevent it from being uncomfortable to the foot of the wearer of the shoe.

lVhile this describes my invention as I preferably make it, it will be readily seen that my object may be accomplished in a variety of ways without departure from my invention.

\Vhen it is desired to have perfect and free ventilation of the shoe the knob D2 is moved so as to bring the movable plate D and the perforations D thereof to register with the perforations B and 2, and in which position it is retained by the curved end D3 of the plate engaging with the front recess E.

Whenever it is desirable to exclude moisture the knob D2 may be readily moved so as to bring the movable plate into such a p0- sition as to close the perforations. I

.I am not awa're'of any means having hith- Aerto been adopted by which a turn or sin le 4 soled shoe may be ventilated without the 1ntoduction of an internal Ventilating appli-y ance which at once defeats the object lof having a single soled shoe., By the use of my invention this difficulty is entirely overcome.l

I am aware that shoes have been ventilated by means of holes extending through the upper sind also through vthe shank, and ywhile these shoes may provide more or less ventilation they fail to provide protection against the entrance of moisture through these ventilating holes when such protection is necessary, and this my invention eflectually makes provision for.

While my ventilatinv shank stiffener is a perfect Ventilating app iance it also gives an additional value to the shoe through lts utility as an effective stiffener and arch preserving device which it is practically impossible to roduce in the ordinary methods ofshoema ing, and I desire to emphasize the value of this feature of m invention.

Where it is desire to use the appliance ex' clusively as a shank curve-forming, sustaining or stifening device it is ap lied without re erence to the Ventilating ho es.

To attain the stiffness necessary to 'preserve the shape ofthe shank of ashoe the usual method is to introduce between the soles either steel, wood, or other stiffening substances that are-either bulky or liable in wear to break and in breaking destroy the appearance and usefulness of the shoe, but in the event of my Ventilating shank stifener being damaged from any cause, it being applied to the outside of the sole, instead of inside the shoe, or between the soles, maybe readily and inexpensively replaced.

My shank stlffener will also furnish a means whereby an ordinary shoe having the shank damaged as aforesaid may be restored to its former shape and usefulness with the additional value to such shoe of the` ventilatinifeature comprised in my invention.

y Ventilating shank is also particularly valuable in use in connection with rubbersoled sportingand other shoes both as furnishing a shank stiffener and also'asa means of ventilation, neither of which` results have been attainable underany methods hitherto adopted in making such shoes.VY l

While I have enumeratedv the principal features of utility, durability and general improvement comprised in my invention, it also adds value to the appearance of a shoe infutiishing a permanent shank decoration or finish.

While I prefer to make my Ventilating shank stifl'ener of metal any other suitable material may be used.

What I claim as my invention is: 1. The combination with a shoe havlnga shank provided with a series ofV erforations I extendlng longitudinallyA thereo of a strip affixed to the outer side of said shank and longitudinally thereof, said stri being adapted to be slid longitudinally an to flexibly conform to the arch of the shank, and

exterior arch supporting Ventilating shank` stiflener comprising a retaining member fixed to the outer side of said shank and a perforated metal strip adapted to slide between said fixed member and the perforated shank, the 'retaining member having perforations permanently registering with the perforations in the shank, and the sliding member having perforations adapted to be brought into `register with the perforations in the shank as specified. 4. In a ventilated shoe an outer sole havin a de ression in the outer side of its shank an per orations in said depression extending through the sole, and an exterior arch-supporting ventilatin shank stil'ener comprising two erforate strips, one alixed to the outer si e of the outer sole and havin its perforations registering with the per orations in the shank andthe other ada ted to slide above said fixed strip in said sion to register its perforations with the perforations in said shank and both strips flexibly conforming to the longitudinal and lateral curves of the shank of the shoe as specified.
