Application filed October 19, 1915. Serial No. 56,766.
Be it vknown that I PHIL@ .FAIRCLEUGH DOUGLAS, :i subject oi the King y'of Great Britain, residing at Minnedoso', in the Erevince of Manitoba' and Dominion of Canada, have invented certain newand useful Im proveniente in Cushion-Insoles .for Boots and Shoes, of which the following is a specification.
lThe present invention appcrtains to improvements in insoles for boots :ind shoes,
y and is especially 'designedto provide for cushioning the jars incident to Walking as Well as to afford :i desirable ventilation for thefoot.
'invehtion is provided on its under surface with yieldable rib members purposely er ranged in e special manner with a view to preventing the tendency of the insole to buckle or. slide about in the shoe in which it is disposed.
It is furthercontemplatfxl to employ in conjunction with the yieldable members hereinbefcre me icned an auxiliary cushion `coperoting -ith said members to sustain the Weight of the wearer and attain a maximum amount of resilient action.
F or a full understanding of the present invention, reference is to be had to the fol- 4 sition; Fig. 2 is a perspective View of the i tbc interior of a boot or shoe.
embodiment of my invention; andFig. 3 is an enlarged vertical sectional View teken aboutY on the line 33 of. Fig. 1.
Referring to the drawing, the numeral 1 designates a. shoe of conventional form and construction, being provided with the' heel 2 which is formed with an inner centrali located reco 3 to receive an element o' the insole structure forming the subject 'matter of this epplicatibn. The insole consists of the upper layer or body 4 which muy con.. sist of cork, heavy canvas or other simil-xr flexible materiels shaped to conform to Beneath the upper. lever 4 of the insole is attached by Ineens o adhesive or the like the cushioning means of this invention, said means comY prising e layer of material 5 conforming to the shape of the upper layer gli and pref-I embl'y attached thereto by means of edhesive.
1n carrying out this invention the undelr-l layer 5 preferably composed of rubber,i
and has integrally formed thereon a, plu.- rality kof rib membe 's disposed in spa-ced relation and extending from the rch or forward portion of the heel to the toe portion. of the insole. By reference to Fig. i? it will be noted that these rib members consist of; firstly, substantially longitudinally arranged elements 6 which are formed sdjacent to the lateral edges of the sole,`fol Y lowing the general contour thereof; and, secondly, of the substantially transversely arranged elements 7. It will also be obn lserved that tl'iese inner or transverse rib members 7 are curved slightly longitudinally in opposing directions.
All of the rib members at 'that portion of the insole corresponding to the arch of the foot are of heavier or thicker formation than the remaining rib members beneath the toe portion of the insole. The function of these rib members is 'to hold the insole spaced from. the sole of the shoe and to provide e cushion to receive the ier of the foot incidental to Walking, running or 'jumping'. The particular arrangement or" these rib members is im essential feature of this invention inasmuch es they designed to perform the yielding action Without collapsing orf lateral bending of the rib members. Tb ns the longitudinally disposed rib members il tend to resist any sliding action or movement of the insole owingr to the natural. pressure ofthe foot in a. forward direction while the transversely arranged rib mehr bers i' resist the tendency to lateral Inovexnent. Thus the transversely arranged rib meinbers substantially counteract the yielding ect-ion of the longitudi-nellyerrnnged rib members in latere-l directions, and vice verse. Therefore the yielding of the insole upon pressure oi the foot thereupon is the natural resilient action inherent to the material of which the cashier-i110 means is composed.
At the heel poi of the insole 1s located a. spiral spring 8 which is attached to the insole or upper by means of fastening members 9, the under layer 5 being cut away cushioning element which is design( l to hold Athe heel 'portion of the insole spaced from the. heel of the shoe, the spring being of sufficient strength to adequately cnsllionv the jar and yicldably sustain the weight of the wearer of the shoe. The spring at itslower end is disposed in the licei recess -l and this interlocks the-insole 'with the heel at the.
rear end 'ot the construction so that said brought into contact with the heel t0 fOl'mV a `rieldable .cushion auxiliary to the spring N, this combination affording a maximum amount of. resiliency at the point where. the greatest pressure is exerted upon the insole. The rib members atthe arch portion of the shoe being strongcr than at'tbevtoe portion naturally receive a relatire proportion ofi the weightor pressure at this point, and where the. pressure is least, as at thevtoe portion, the rib members 'are slightly more yicldable1 as above described.
' The upper and .lon-'cr layers 4 and 5 rcspectively are formed with av plurality of apertures 11 So that as-the insole yields under pressure, of the foot the air beneath the vinsole is forced upwardly through the openings and thereby all'ords a. ventilation for the foot.
At the-heel I preferably attach a cm-'er n'ien'iber 12 which is designed to protect the wearer from any rouglmess dueto the securingr of -t'ncspring S by means of the. fasten- )Hg members U, the cover being of' any de? such case the insole, particularlr about the" toe portion of the. shoe, would be attached by the usual stitchingr furthe regular outer sole. lt will also be `|uulerstood that the strength of the sprinxgr h' and the ribs 6 and 7 may be. gaged according to the. weight 'of the ii'ea rer of the -particular style'of Shoo,
Having,r t'ius described the invention, what is claimed is:
1. An insole. construction for boots or Shoes comprlsmlcr a layer of lexiblc material,
cushion means attached beneath said mate rial at the toc portion oll said insole and ('onsistingr of a. plnralit of rib ln`e|`n l )ers. and heel cushioning means ron'iprising a primary cushion member consisting*r of a coniprussihle springr normally holding the. heel port-ion of the insole spaced from the. sl|oe-heel, and fi secondary cushion member consisting of `a rib clement substantialtr surrounding thel spring, normally sparedv from the shoe heel, and adapted to receive. the. jar' upon com-- pression of said spring. Y
2. An' insole const-rxuztion 'for boots or shoes comprising an upper la, ei`- of'` flexible. material and a lo\\'er '|a \er of rubber material havinv formed thereon a. plurality iol?v elongated rib mcl'nbers, certain of said. rib
'melilla-.is being arranged longitudinally of the .sole and adjacent to its edges, `andjcertain ofylsaidrib- I nembers` lxing arranged transversely of thc sole. intermediate thelateral rib nwmbcrsfaforesaid, thc rib mclribers at the central portion of the sole. being rela.- tirely larger than the rib members at thefend portion of said sole.
