I Specication'of Letters Patent.
Patented Aug. 23, 1910;
Application filed January1- 11, 1910. Serial No. 537,427.
To all whom uf'may concern.' y
Be it known that I, ANTONIO YANDOLI, a subject of the King of Italy, 'residing at 1 West @ne hundred and thirty-first street, New York city, New York, have invented new and useful Improvements in Shoes, of
lwhich the following is aspecification.
I'his invention relates to an improvement -in shoes, and more especially to shoes prolvided with means for .supporting the archof the footsuch as are used by persons hav-4 on a line A, A, of Fig. 1'.
ne of the objects of the.in vention'is to .provide a shoe in which the arch of thefoot will be prevented from'lattening when subjeed to the pressure of the weight yof the Vbo .Aiiother `object is to provide a device of thischaracter in which the arch will be more 'firmly supported at the instant when the foot strikes the ground in the actof walking.
Other objects will be in part obvious and 1n part-pointed out hereinafter. p
In the accompanying drawing showing an illustrative embodiment of this invention, andin which the same reference numeral roh fers to similar parts in the several figures; Fi re 1 is a longitudinal vertical section of a siloe constructed in accordance with this invention. Fig. 2 is a sectional view` taken Fig. 3 is a plan view of the metal strip and its associated spring, the disk being removed. Fig. 4 is a perspective view of the inner sole.
In the iIlustrative embodiment of this invention Shownin the drawings, 1 indicates the upper portion of a shoe of any appioved type and 2 the outer sole thereof. The inner usole 3 is provided at its sides with oppositely disposed upward extensions 4 and 5 which are so positioned as to co-act-with the arch of the foot to act as a brace therefor.. These extensions 'are integral with the sole, and ,as clearly shown in Figs. 2 and 4, the inner extension 4 is higher and' thicker than the4 outer extension 5, as a more firm support is needed upon the inner side of the foot than is needed on the Outer side. The extensions furthermore tend to keep lthefshoe in its proper shape and prevent the same from wrinkling. l
Positioned intermediate the inner and outer soles and extending throughout a portion of the length of the shoe is a lexible plate 6, referably formed of metal and having its orward end lfixed against longitudi-- nal movement relative to the sole of the shoe in any suitable manner, as, for example, by a rivet 7 The plate 6 is preferably upwardly curved at its central portion and its rea-r portion Sis positioned within a recessv 9 formed inthe heel portion of the outer sole. The depth of this recess issuch as to allow vertical movementof the end 8 of the 'plated As clearly shown at 10 in Fig. 1 the plate bears. against the upper edge of the forward wall of the recess 9 thereby forming in eEect a pivotal point, so that when pressureis applied to theend 8 of the vplate as hereinafter-described, the central portion. of the plate which lies under the arch .of the foot will be caused to movein an upward direction. v A
Positioned between the end 8 ofthe plate and `the heel portion of the inner'sole' 3 is n 'the embodiment shown, consists of a conical' spring which acts as a shock absorber when thewearer of the shoe is walking., In :order to-provide a suitable bearing surface for the upperportion of vthe spring ..1'1, I preferably. placca metallic disk 12- 'between the spring and the inner sole 3, which disk may be secured to the spring or the inner sole in any suitable manner.
The operation of the device, which should be largely obvious from theabove description, is as follows: The partsare so adjusted the foot ofthe wearer, and more especially as the foot strikes'the ound -in the act vof walking, the pressure ue tothe weight of the body acting u on the heel 'portion of the inner sole will, t rough the medium of the spring, cause the rear? end 8 of the plate 6 to be depressed, and inasmuch as the front end of this plate is's'ecured against longtu dinal movement, it 'will be seen that the central portion of the plate which lies beneath the arch of the foot will be raised, thereby forming an efficient support for the' arch of the foot. The arch of the foot is'further supported by means of the upper' '75 a' pressure transmitting member 11 .which extensions 4 and 5 of the inner sole, which will also move upward when pressure is ap- `plied to the heel, asA above described. It
will of course be understood that the upward movement of the plate 8 will be greati est at the time the foot strikes' the 'ground wheniin the act of Walking, and this is vthe moment when the greatest support should be given to the arch of the" foot.
l It will be seen from the above description that I have provided a shoe well adapted to use by persons having weak insteps. The'shoe' furthermore is simple in itsconstruction and inexpensive to manufacture. Y Having described this invention in connection with the illustrative embodiment thereof, to the details of which disclosure the .invention is not of course to be limited, lwhat is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims:
1. In a shoe, 1n combination, an outer sole, an inner sole, a plate interposed between sai`d soles,`said outer sole being provided with a recess within which the rear end of said plate extends, and resilientpressure vtransmitting means interposed between the rear portion of said plate and the inner sole, said means being movable bodily with respect to said outer sole.
2. In a shoe, in combination, an outer sole, an inner sole, a flexible plate interposed between said` soles land extendingr throughout a portion of their length, the
sole being provided with a recessin its heel portion within whiqh'the rearend of said tion o l ont portion of said plate being fixedl against lon itudi' nal movement relative'to the shoe, sai outer plate normally extends,l and is. adapted to ave vertical movement and resilient pressure transmitting means interposed between the rear portion of said plate and said inner sole.
3. In a shoe in combination, an outer sole, an inner sole, a flexible plate interposed between said soles and extending throughout a ortion of their'length the front por- ?said plate being fixed against longitudinal movement relative tothe shoe, said outer sole being provided with a recess in its heel portion,within which the rear end of said plate normally extends, said platebearing against the up er edge of the front wall of said recess, an -resilient pressure transmittingmeans interposed between the rear portionof said plate and said inner sole.
4, In ashoe, in combination, an outer sole, an inner sole and a plate interposed between said soles, said outer sole being provided with a recess within which the rear end of said plate extends, resilient means interposed between the- Tear end of thel late and the inner sole,said shoe being free romV supporting means interposedy between the rear -endof said "plate and said, outer sole.
`In testimony'whreof I have signed my name to this specification in the presence of two subscribing witnesses.
