My saidinvention relates Vmore particularly t0 the heel construction of overshoes of the type designed to be worn over ladies high heeledshoes, and is designed particularly as an improvement in the Vheel portion ofthe overshoe shown in an application filed by me in the United States Patent Ollice on the 8th day of October, 1928, Serial Number.311 ,096, though not limited to the particular shoe therein shown. V

Duel to the extreme height of the heels of Y,

the great majority of shoes worn byyladies,

great diiculty has been experiencedin sel, .curing overshoes in whichtheheel portions or pockets would withstand the strains and hard p usage to whichl they were subjected by such type of shoe., t,

rThe present invention aims to provide a i heel construction which will lbe' free from such defects or wealmessand one which will enablethe various parts to. be readily and economically assembled to produceva' strong and durable article, ,and a method ,of'producing such article. Y,

f The invention further aims to providean overshoe of-the highheel typewwhich will have at the bottom thereof arubber heel llift lift commonly employed on leather or wooden without the use of nails or thelike, so as to t be incapable of displacement.4

With these and otherjob'ects in View, the

invention includes thel novel articleherein-Q after described and ldefined by the appended claims.

`In order that the invention maybe more i readily understood, reference is made to the A embodying my invention.

accompanying drawing in which :V l

Fig. 1 is acentral vertical lengthwise section through therearporti'on'of an overshoe Fig. 2 is a section on line 2 2 of Fig. 1.

' Fig. 3 is alperspectiveview ofthe heel lift.A

Fig. 4 is a view similar4 to Fig.; 1 showing the parts or layers separated. orspaced apart so as to enable them tobe more clearly identified. 'p Y Referring. by Yreference characters to this drawing, theletters E, F, designate the usual upper material which is extended downward to a suiicientl extentto form Vthe back and side walls ofthe heelv pocket, as indicated at 1E and F', F being therupper'fabric'lining andFi'the upper gum layer.v G and H respect'ivelyv designate the customary layers of insole fabric and #l fabric filler sole respectively whicharecontinued down to form minate Vat the breast corners ofthe heel. I and J designate the :ft2 fabric liller sole and and gum outsole whichextend down over the breast ofthe heel pocket, as indicated at IV J. 'Y i 1 Y Y y v i L designates a" rubber heel lift provided l with anintegraly upstandingflange L which lies between the upper material andfback piece and also between thefinner breast lay.v-l

ers G Hfand outer breastlayers I J Said flange is set back from the edge of the heel v which will simulate in appearancevthe heel liftso as-to providea shoulderL which extends around the back and sides and across heels, and whichwill ,be `firmly attached,l

thebreast of the heel; This heel lift L is vulcanized to provide a relatively hardor lirrn wearingsbodyfof suitable stiffness coinpared to the rest of the shoe.

D designates a Vfabric binding strip which INC., OF WILMINGTON, DELAWARE, A'CORPORATION OF DELA- ACH madefrom rubber compound similar to the Y f ordinary heel for leather* shoes land isfully extends around the outsideoflayer parts E and H andV is continued for4 a distance beneath layer H2, as indicated at D.

l V4K designates a` fabric reinforcement which is placed on the topV surface of the heel litt 'and extends for a suitable distance up against v theinnerface of flange L asindicated at K',

and embedded i'lush therewith in the process of vulcanizing the heel.'` p 1 C designates a gum'bacl piece filler which encirclesthe flange L and extends a' suitable distance 'above the same, and makes a; Alap joint at` the front thereof.

f It will be understoodthat the 'various' parts-v 'ico i are made of rubber or rubberized fabric assembled on a last and vulcanized together to form a unitary article.

In constructing the shoe, the layers G and I-I are first combined and applied to the last as a laminated sheet, and blanks E and F are similarly combined and applied, their edges overlapping G I-I at the breast corners of the heel, and for this purpose being extended slightly around the said corners.

The binding strip D is then applied and thereafter the vulcanized heel lift L is put in place, the fiange L being telescoped over the heel pocket, the fabric reinforcement K having been applied and imbedded in the heel in its process of formation. To accomplish this step, the upstanding ange L of the heel lift is coated with a. suitable gum cement, and while wet, is slipped onto the heel formation to properly seat thereon, the fresh cement acting as a lubricant and facilitating the teleseoping action.

The gum back piece filler strip is then applied entirely around tlie heel, lapping at the front, whereafter the back piece layers A B are applied as a laminated blank being preferably lapped over the breast corners of the heel. Thereafter, sole layers I and J are successively applied which completes the building of the article, except for the application of the ornamental beading strips M and M.

It will of course be understood that the various blanks formingthe upper and sole parts may be modified according to the nature of overshoe desired. Obviously, the blanks E F and A B respectively, could, if desired, be cut fioin sheets of fabric having rubber calender-ed thereon; for eXa-mple, instead of independent superposed sheets.

I claim:

l. In an overshoe Vof the type described, a

heel receiving pocket comprising inner and outer layers and a rubber heel lift having a continuous integral upstanding flange lying between said inner and outer layers and a tread surface adapted t-o foim the outer tread surface of the heel.

2. In an overshoe of the type described, a heel receiving pocket having inner and Outer pocket wall forming layers, and a heel lift having a continuous integral upstanding flange on its upper face lying between said layers, said flange being set back from the edge of the heel to provide a marginal shoulder against which the lower edges of said outer layers abut.

3. In an overshoe, a heel receiving pocket having its Walls formed of inner and outer layers, said inner layers in part extending across and forming the bottom of the pocket, a binding strip extending around the corner of the pocket, and a rubber heel having a continuous integral upstanding n flange lying between the outer layers and said inner layers and binding strip.
