Before :this platform member 2.2 is applied to .the shoefan edge vbinding yor lcovering Vstrip, 44 is. appliedso-asfto Coverall portions .of the edge vof the member, -except its rear edge .face45 (Fig. 1) and towoverlap .the adjacent :margins .of its upper and lowersides, as `bes-t shown inEig. 1, the covering strip being..advantageouslysecured .in place by Vmeans. of cement. This foreport `platform member 22, with .the edge. binding or'covering 44 thereon, is shoe bottom, as shown in Fig. 5,. its position lengthwise of the shoe being accurately gaged from thetoeend ofthe shoe, and .it istemporarily secured in place by means of staples "46 which are. driven into the` insoleand are left upstanding,-,as shown, so;tha t .later they .may be easily removed.

The rear platform member. or heel and shank pieoe-24 is ,preferably ymade `of wood and .is shaped to correspond in marginal contourto that of the heel yand shankportion of theoutsole of the shoe. `The memberY 24 .has a fiat bottom 'face 48x-and it is Ainadeo-f substantial thickness to take the place of ya heel. The front portion of ythe member 24 yis tapered at its upper side, thus providing va `wedge .forma-tion. for filling the varched portion of the shoe bottom. The forward extremity ofthe .member 24 .ishotohed or rabbeted Iat its lower side to receive the .rear portion of thevv forepart :platform member 22, the rabbeting operation forming a vertical shoulder 50 .of a height equal to the thickness of the forepart member. 22 and .a lip 52 which-.extends forwardly vfrom the shoulder 50 tooverlie vand be secured to the forepart member. member, 22 has ybeen temporarily ysecured tothe shoe as described, the rear. member or heel-andshankv piece,

end of the shoe. The rear part member having been located lengthwise of the shoe and the op# lip 52 having been alined with the corresponding edges of the rear extremity of the forepart I:member 24, staples y54 sare driven through the latter and through the lip 52 and into the insole to secure the forward portion of piece to the shoe. The covvwhich at this time extends from its area of attachment to the shoe bottom upwardly in embracing engagement with the upper, as show-n yin Figs. 4 and 5, is inverted, i. e., it is turned away from the upper and toward the edge Aof the 'heel 4and vshank piece 24 to cover the latter, and the free marginal portion of the covering strip iis -folded inwardly upon the flat bottom face 48 of the piece 124 ,and .secured to the latter as by means of .tacks 56 (Fig. 6).. Inasmuch as the covering r.strip4 34 extends forwardly a-short distance beyond the rear extremity of the forepart platform member 22, theforward portion of the covering strip overlaps the rear portion of the edge binding or covering 44 on the forepartmember, as clearly shown in Figs. Grand "8, so that a neat joint is formedbetween the two covering strips 34 and 44. Y

At this stage of operations, the`last'36 is withdrawn from the shoe. The forepart platform member 22 is then lpermanently and securely attached to the insole lby means of through-andthrough stitches 60 which are sewn so as to extend through the inturned 'margins of the edge binding 4'4 and through the member 22 and the insole I6 and the staples 46 which served as means for temporarily securing the member 22 to vthe, shoe are removed. As shown in Figs. 6 and 8, the stitches 60 at the rear extremity of the forepart member 22 extend Valso through the lip 52 of the heel and shank piece '24 .and through the inturne'd margins of the heel-and-shank-piece covering 34, thereby securing together the overlapping portions rof the coveringstrips 34 and V44 and supplementingthe action ofthe staples been Acustomary heretofore to employ a one-piece platform sole of full shoe length and to determine its location lengthwise of ing the position of the toe end of .the sole with reference to the toe end of the shoe. VThe practice .of such a .method of locating platform .soles the same as with which it is to be used. y In preparing the Iparts of -m-y improved twopart platform.. however, it is unnecessary to furnish yplatform ,parts in 4a vcomplete run of sizes since, byassembling the two partsof a platform Vso that the lip 52 of the rear part member overlaps the forepart member more or less accordabutting relation y part, and the lip and expense in making vone-third or one-quarter as many sizes need be 'provided as would 'claim as new and desire to secure covering strip with an insole on a ing to the size or length of the shoe, platform parts of one size may be used upon shoes within a range of several sizes. smallest size with which platform parts of a given size may be used the rear edge of the platform will be disposed close to, or substantially in to, the shoulder 50 of the rear 52 of the rear part will overlap. the forepart throughout substantially the full width of the lip as shown in Figs. 5,17 and 10. Platform parts of the particular size above mentioned may be used with larger shoes within the range of the next two or three sizes, however,-in which cases there will be spaces of different width between the rear part shoulder 50 and the rear edge of the forepart, these spaces and the amount of overlap of the rear part lip upon the forepart platform member varying accordingto the particular size of the shoe. This practice of v using one size of platform parts for several sizes of shoes results in a substantial savingvof'time the platform sinceonly be necessary if one-piece platforms were employed. There are various other advantages incident to the construction and method of making my improved platform shoe. For example, by providing separate coverings on the forepart and rear part of the platform, the platform covering operations are simplified, it being unnecessary to pattern the covering strips forv covering the relatively thin forepart and wider portionsfor covering the relatively thick rear lpart of the platform and there being'no difficulties such as 'those involved in the application of a covering strip of non-uniform width to a platform of non-uniform thickness. Also, by

' employing for the heel and shank portion of the lplatform a covering strip which has been preattached to the upper, the covering ,operation willresult in drawing form close to the bottom of the shoe andvthere will be no gap between the covered upper margin of the lplatform and the upper of the shoe. v,
