ncis, have invented certain new and useful.

Improvements in. Resilient Heels and Soles, ol which thc lollowmg is a specrlication.,`

My invention relates to certain new and useful im rovemcnl's in resilient heels and soles l'or shoes and boots, which consist in the arrangement of parts and details of construc tion, will be hereinafter fully shownv in the l drawings and described and pointed out` in the specification.

The principal object of my invention is to "provide a heel and sole oi great resiliency, while at the same time imparting rigidity and stillness to them. A

Anotherobject ol the invention is to embed wire and Tlinely-woven wire in a heel end sole, not only to give them proper stiffness, but also great wearing qualities.

Another object of the invention iste rovi de means orpositively securing a resi lent heel to a boot or shoe.

A further object of my invention is to con struct a heel of' rubber compound. to insure the wearer rdinarily against slipping and to enable him to avoid jars andwrenches to which one wearing shoes equipped 'with solid heels is subject.

These and such other objects as may hereinafter appear are zitta-ined by the devices shown in the accompanying 'drawings, in Which- Figure is a perspective view ola shoe equipped with .my improved heel and sole. I Fig. 2- 1s a longitudinal sectional view of a' cross-secH resilient heel. 'Fics 3 and 4 are tional views ol resilient heels. Fig. is a lon.-

gitudinal sectional view of a solid rubbef 6 and t5 are plan vicwsoli 'a sole 7 heel. Figs. land heel framework, and Figs. 7 and 9 are sectional views ol' n. shoe near the t De.

'Similar characters oi referenc' 1icate the same parte in the several figures the drewin s.

ieferring by numerals to the accompanying drawings, l indicates a resilient heel, which is secured to s, shoe by means of stitches 3'. The sole of the shoe isy designated by f2 and the sides by 5.

the shoe by tacks My heel is p'relerabl r `composed ol a soft or porous rubber or yiel I in material 9, which is inclosed by a firm ruber shell having a still' base 13 and slightly l'nsole 6 is fastened to bulging sides l1, which extend into upwardlyproji-.ieting flange edges that nrc firmly seas shown in Fig. 3, the sides olt the' shell extend into llange edges l2, that-are attached to the shoe by means of screws 7 which pass through the insole 6 and. flange edges l2 and engage metal securing plates or rings. Bordering on or quite. near the interior surface of the heel-shell is textile fabric 10, while in its base is embedded flue woven wire 14, which is supported by a framework consisting of wires 15 or the like, which. are integrally se-v cured to the woven-Wire fabric by solder 16. Heretoliore resilient heels have been made to imitate'leathcr heels and secured in the same way. Some heels have been made entirely of rubber and others havehad their upper part composed of leather and their lower part of rubber', while some heels are equi ped with rubber between layers of leather. lime rubber heels have embedded within them canvas midribs,y the object of which is to prevent nail-heads from pulling through. Such midribs are a source of weakness, as thc heel .is likely to split and vtear loose, and7 again, the


I preferably construct my resiliont heel with an inner part l) und an outer shell, the sides 11 being flexible and the bot-tom stili and comparatively thin. l prefer a yielding material other than air to produce resiliency i in the heel, as a pneumatic heel is likely to be puncturedv as well 'as to be more eX ensivc in construction. 'The inner porous-lille flexible material l) is in the preferred construction made separate. and placed wit-hin the shell.

l have shown two ways in which the resili cnt heel may be secured to the slice. In the preferred construction l haveshown the heel l provided. with an upwardly-extending lian fe l edge, by means ol which it is sewed to t 1e l shoe, or it maybe attached to the shoe by l means of e screw passing through the insole and edge of the heel-shell into a metal plate l i l i i l i r l or ring, thus binding the heel to the hoe.

The flange edge oi the heel has textile fabric l embedded in it7 so that the securing means f fo the heel which through the flange l elnge also pass through the textile fabric enibdddcd therein, and the heel is thereby firmly secured to the boot or shoe. Inorder that the soles and heels may have i the proper amount of stiffness and rigidity, I embed within them a frame-work consisting resiliency is lessened by the midribs and cured tothe shoe by means of stitches 3, or,


embedded in ie heels and soleshown in Figs.

y 2', 3, 5, andfwhilein Figs. 4 and Qare shown g frameworks consisting of., mediuin-weight woven'wire Without the larger wires.

"r It is very essential that resilient soles have y embedded' within them a framework of wire,

` "easily that it is foot to walkswit i since "without" ythem rubber soles'yield so' sinful and tiresome to the them over rough' surfaces. To'pro'vide a framework which will allow tli'e Soleto) bendfeaslly as ones 'weightl varies from heel to toe in Walking/I place the larger wires ifi-parallel findet right an les to the length of the shoe.' zThe-paralle' vwires are placed closer together at the place of greatest wear] Thus-lA produce a resilient'sole that possesses snflicientv rigidity and stiffness and at-the' same time affords ease in walking.

- One of the defeots'fof Vthe rubber heels as now put onthe market is that of' rapid Wear. To overcome this,'l-s`older frame-w1res 15 to Wovenwire 14 in such a way that when they' are embedded-within the heel and the rubber isworn 1awayA the l'wire tabric is not exposed until the'frarne-wires are'entirely worn away, and Since the rubber penetrates the wcwen-4 Wirefabric 14 ai'idunites with the .rubberen ,the other side of it the framework is firmly held in vplace inthe rubber heel. lt will be observed, therefore, that my wire framework increases the life and wearing qualities of the resilient heel and sole.

In Fig. 5 Ihaveshown la solid rubber zre'- silient-or ciishion heel with Woven-wire fabric embedded therein. In Fig. 9 lthe upper part of the sole isfcolnposed of leather and the lower art ofrubber with embedded woven wire t erein, and vbetween these layers is a resilient material 9.

it is obvious that chan es in the form and proportion' 'of parts may e made inV ,my in l vention-such as, for instance, any resilient f a heel" composed oi -a resilient core and' an material'may be used infmy heel, even comressed'air, if need lie-andi therefore would ave it distinctly understood that l reserve the right to makeall such lchangesas fairly fall within the sco e of my invention;

Having thus fu l described the invention, what l claim, and desire to secure by Letters Patent, is-
