This invention-relates to certain novel improvements in boot and shoe constructions and has for its principal object theprovision of an improved construction of this character'which will be eflective in use and economical in manufacture.

= The salient object of my invention is to provide an improved means for attaching the sole and heel in position in boot and shoe '1 constructions. I j

1 Another object of the invention, ancillary to the foregoing, is to provide a construction of the above'named char'acter which will be arrangedsuch that the sole and heel may be 'ex peditiously removed when so desired.

7 Other objects will appear hereinafter.

, The'invention consists in the novel combination .and arrangement of. parts to behereinafter described and claimed.

I In the-accompanying drawing wherein I have illustrated the preferred form of construction for my devicelO indicates the outer sole of my improved construction and 11 indicates the outer ply of'the heel construction and this sole and outer ply are preferably formed from a good grade of material as is well understoodrin the art, it being under stood that myinvention is adaptable for use in connection with any type of material; as

for example, leather, rubber, or so-oalled com position material.

In the drawing 12in dicates theusualiir termediatev sole employed in boot and shoe construction and 13' indicates the usual insole. The foregoing portions are ordinary in shoe construction and the formation-there of and the materials from whichthey might best be made is well understood in the art.

In the insole l3 I provide adjacent the edges thereof in spaced apart relation a plus rality of openings 14: which are preferably arranged in the disposition best depicted in Fig. 3 although it is to be understoodthat analogous arrangements might be made without departing from the purview ofumy invention. On the intermediate sole 12 I secure a plurality of so calledanchoring elements 15' which, as clearly depicted in Fig.-11, havepointed projections 16 extending-there.- from and when the device is assembled theseprojections 16 are preferably arranged at right angles to the main body of the mem bers l5 and are inserted into theintermediate sole 12 on the side thereof intended to be directed toward theinsole 13. At substan I tially the midpoint of the main body portion of the anchoring elements15 is a dished outportion 17 and when theintermediate sole 12 is disposed in abutment with theinsole 13 these: dished out portions are intended to be disposed in theopenings 14 it, therefore, being apparent that the members. 15 are arranged onthe intermediate sole "12 in the same'spaced apart relation as exists between the openings 14in theinsole 13. At the toe portion of theshoe I provide a plate member :18 which is arranged so as to be of a c onfiguration substantially similar to the configuration of said toe portion and the dished outportions 17 are formed in thisplate member 18. Theplate member 18 is held in position by projectingelements 16 which are also driven into the intermediate sole 12. At the heel portion of the shoe I provide aplate 19 in which the dished outportions 17 are provided and the projectingelements 16 are also provided on thisplate 19 as clearly illustrated in Fig. 2. lVhen theinsole 13 andintermediate sole 12 are arranged such that the projections created by the dished outportions 17 are disposed in theopenings 14 these two soles are stitched together in the manner well understood in the art.

Prior to the time the insole and intermediate sole have been secured in position on the upper and prior to the time they are secured together I arrange thefastening elements 20 and 21 in position. The fastening elements 20 are arranged such that the head portions 22 thereof are disposed in the dished outportions 17 on theanchoring elements 15 and theplate 18 and such that thehead portions 23 on theanchoring elements 21 are disposed in the dished outportions 17 in theplate 19 and theshank portions 24 and 25 of theelements 20 and 21 are extended through openings in the intermediate sole l2 and through openings in theouter sole 10 and the outer ply 11, it being understood that theshank portions 25 also extend through theintermediate plies 26 in the heel construction.

In theouter sole 10 and the outer ply 11 in alignment with the openings through which the shank portions 2& and 25 extend I provide conical openings such as those indicated at 27 in Fig. 4: it being apparent that the wider portion of these conical openings is outwardly disposed. Securing elements such as 28 are provided which have conical peripheries. Oppositely disposedslots 29 are formed in the securingelements 28 and axialiy arranged tappedopenings 30 are also provided in these elements. The outer ends of theshank portions 24 and 25 are threaded ant. these threaded portions are disposed in theconical recesses 27. Therefore, thesecuring elements 28 are arranged such that the threaded end portions of the shank portions may be extended into theopenings 30 in these elements. In order to facilitate the positioning of the securing elements 28 I provide a tool such as 31 (Fi 8) which includes ahandle portion 32 and abifurcated end portion The bifurcated end portion is arranged such that the prongs thereof will be disposed in theslots 29 and, therefore, thesecuring elements 28 may be expeditiously screwed into position so as to securely fasten the outer sole 10 and the outer ply 11 in position. In Fig. 7 I depict a modified form of construction for the tool and herein I show a tool 3e having a bifurcated end portion 35 substantially similar to the bifurcatedend portion 33 and thistool 3 1 is mounted in thebody portion 36 of a so called pocket-knife construction which includes ablade 37. It apparent that the sole 10 and the outer ply 11 may be expeditiously removed and replaced by merely unscrewing thesecuring elements 28 through the use of a tool such as that described.

In Fig. 12 I have depicted a modified form of construction for the securing elements which will be particularly adaptable for use on so called sport shoes and in this instance I have provided on the outer surface of the securing elements 28 projecting portions orcleats 38. g

It is to be understood that while I have described one arrangement for the anchoring elements 24- and. 25 and thesecuring elements 28 it is to be understood that these parts might be interconnected in different manners without departing from the purview of my invention.

While I have illustrated and described the preferred form of construction for carrying my invention into efiect, this is capable of variation and modification, without departin from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is:

1. In a boot and shoe construction. an insole, an intermediate sole, anchoring elements on said intermediate sole, an outer sole having recesses therein, means for interconnecting said soles comprising fastening elements including head portions mounted in the anchoring elements on said intermediate sole, and securing elements disposed in the recesses in said outer sole and connected to said fastening elements.

2. In a boot and shoe construction, an insole provided with openings, an intermediate sole, anchoring elements on said intermediate sole having dished out portions therein projecting into the openings in the insole, an outer sole having recesses therein, means for interconnecting said soles comprising fastening elements including shank portions and head portions whereby said head portions may be disposed in said dished out portions and said shank portions may be extended into said recesses in said outer sole, and anchoring elements mounted in said recesses in said outer sole and engaging said fastening elements.

3. In a boot and shoe construction, an insole provided with openings, an intermediate sole, anchoring elements having dished outportions therein projecting into the openings in the insole and means for attaching said anchoring elements to said intermediate sole, an outer sole having substantially conical openings therein with the wider portions thereof outwardly disposed, means for inter connecting said soles including fastening elements'comprising shankportions and head portions extended substantially at right angles to said shank portions, said shank pore tions having the outer ends thereof thread ed, said head portions being disposed in said dished out portions and said shank portions being extended so as to dispose the threaded end portions thereof in said recesses in said outer sole, and substantially conical anchoring elements having screw threaded openings therein whereby said substantially conical anchoring elements may be disposed in said substantially conical openings insaid sole with the screw threads on said anchoring elements in engagement with the screw threads on said shank portions.

In testimony whereof I aflix my signature.

CHRISTIAN WALTON.
