Massg'a corporation of Delaware Application mm, 1943, ser arnuiisa ize I v j ;17 emails; This invention relates to shoes and their; man-1 ufacture and more'particularly to the "securement of outsoles and heels to the heel seats-of- V lasted shoes. e I i In the manufacturing of shoesit is usual procedure to complete the lasting operations to se-,

cure the upperto the shoe insole, secure the shank stiffener piece in place, and then attach the outsole at its heel end tothe'heel seat of the shoe with staples or tacks. 'I'hisprocedure locates the outsole with respect to the shoe bot-- tom and yet allows the sole to be bent 'away' from the shoe bottom in order to facilitate application of a cement solvent or softener to the cemented surface of the sole and/or upper, prior: to placing the assembly in a, pressfor .perma nently attaching the sole to the shoe bottomwas.

described in the patent 'to ."Bresnahan No.

While the above procedure may be satisfac tory for shoes to which a heel is tobe secured by nails after the last is withdrawn from the shoe, it has disadvantages when used in -manu-' facturing a shoe to which the heel'is to be secured while the shoe is on the, last by means.

, of 9, fastener passing through the borein the last; as there-is nodefinite-means of locating the shank stiffener piece andsole securing staples or tacks with-respectto the point where the heel fastener will penetrate theheelseatma.

terials, and it very often occurs that the shankstifiener piece and/or the sole securingstaples.

are placed so that they are in .thelpath of the. tools which operate through the last bole to forma hole for, and to insert, the heel fastener, resulting in excessive breakage. of the tools and frequent misplacement of the heel fastener causing unnecessary expense and delays improduction.

From the above itcan readily be seen that ac curate positioning and securing of the shank piece to the heelof the shoe is necessary and to this end it has been proposed to -pre-drill f 'o r, or mark upon, the heel seat materials the'loca: tion of the heel fastener by tools guided by the last bore. However, this is an added expense and at best it serves onlyas a visual aid in'plac-- ing the shank piece and does not prevent placing of the shank piece'over aportion "of"the hole or mark on the heel seat materials, and as the hole or mark is covered and hidden fromf view'when attachingthe outsole tot he shoe heel seat, the staples, which must be located somewhat to the central portion'of "the heel seat in order to avoid the dies or knives later used to cut on or "trim the heel end of the sole for receptioniof the heel, can still be placed in the pathof the 'heel fastener and thereby;cause the scope of the invention will be indicated in;

damage to thetools usedto drill and drive in ;place; the heel fastener; a

1 It 'is,-; therefore, an: object-of this invention to provide: novel means ;.for securing'the heel end of an; outsole to the heel seat ofv a lasted shoe ina manner which is {both economically andstructurally -beneficial.

Another object of the invention is to provide a novel methodof placing and securinga shank stiffener piece to the heel seat of ashoe. A further object of the invention is; to I provide .a shoe with a sole that is securely fastened to the heel seat materials with" a fastener which serves as a, heel fastener socket; Y

Still further "objects of: th invention are to improve heel seat construction of shoes and attachment of heels"thereto, and to reduce breakage, of tools during such operations;v

Other objects of" thev invention will in fact be;

obvious and will inpart -appear-hereinafter-., '1

The-invention accordingly comprises the sev= eral'steps and. "the relation-of one or more of such steps "with respectto each of the others,

and: thearticlepossessing the features; proper ties, and the "relation-of-elements, which will be exemplified in the-followingdisclosure, and

the claims. 1 a

I For a fuller understanding of the nature and objects of I the invention; reference should be had to the following detailed description taken,

' in connection with the? accompanying drawing,

in which: I i

Fig. 1 is a fragmentary sectional view'of a lasted sh'oe showing=.onewmethod of forming a hole in the heel seat materials and outsole of. the shoe in alignment with the heel" fastener rem the sole'and shankpiece 'to the heel seat of the' shoe;

Fig. 4"is "a" sectional plan-view taken substan.

tially along-lines 4-4 of Fig. 6; I i

Fig. '5 *is a fragmentary sectional view of a shoe prepared in accordance with-the showings o'fFigs; l to 13 and showingthe drilling 1of'the Referring to the drawing, there is shown in Fig. l, a last 10 havln'galast pin ferrule I I form ing a heel fastener receiving bore l2, and the usualmetal heel plate l3 for clinching the heel; seat lasting tacks. Mounted on the last I!) is a,

shoe which may comprise an upper ll'havingits lasting allowance secured to the desired manner.

,An outsole I6 is placed in p osition on the insole l in-any;

is surrounded by the metal spacing walls of the bottom and .the complete assembly is placed on av last pin l1 of a punching and eyelet setting ma+-= chine having a punch I8and a die l9. Aneyelet is placed on the punch l8 and in operation of such machine the last pin ll'moves upwardly to ciamp'the shoe'against'the dielS, andthe punch f8 is reciprocated in the'bore are: the last-pin sufficient to form a hole'i'n the 'heel end of the" outsole IS, the insole I5-anet anyother materials forming the heelseat or the shoe; in alignment with the heelfastener recei-ying bore I 2. After forming the hole th'e pulfich NF continues-its re-: ciprocatfon and d'rives theeyelet 20 intothe hole formed as the die I9 is retracted as'i l'lustrated In this 'conditionthe forepart andshank ar- 'tions ofthe outsole ifif'a're lirtedl'away from the" shoe bottom and a' metal shankpi'ece flf is in serted betw'een the insole m'and the outsole" 16 with the-forks 23" straddlingthe eyelet was illustrated by Fig. 4; 1 f v The end of'the shank piece zrmaybei'then located with respectto the ball of thesho'erand.

re-aligned with theshoe bottom and the die l9 eyelet 20. I

Referring to Fig. 6 a screw 34 is driven into the heel by a driver guided by the last pin 3| 'and the last ierrule I I, thus the eyelet 20 is seen to act as a screw-receiving socket so that the more the screw is tightened to pull the heel to the shoe, the more the heel.- seat materials will be held together and this without any danger of the head of the screw pulling through the heel seat materials. The screw contacting portion of the eyelet is shown by Fig. 6 to be formed compleziientaltoth'e inner screw surface contacting a same.-

' ffs ineel'certain changes may be made in carrying'fltlt the above. process and in the product, and modifications effected in the apparatus described for'practicing the principle thereof, without'departing from the scope of the invention,it is intended that all matter contained in the above description or show'n' in the accompanying drawing shall beinterp-reted as:illustrative and not in alimiting sense.

It is also to be understood that the following claims are intendedto' cover all of the generic and specific features ofthe invention herein -de'- scribedjan d allstatements of the scope of the: I
