eSSafy fo1 the shoe Sopporf fo have any n1ove Inent othe1 than heightX iSe of the Shoe and, acoofdingly, a furheI featuTe of the invention consistS in the proviSion in 94 Shoe n1aohiBe hav ing a work support ffeoly 1novble longthvVise and widthWiSe of the Shoe, of lneonS foT looking the Shoe Support againSt such lengtf1f ZiSe nd widthWise Tnovementn the uSe of the illustrated 1Tlaohine, it iS neoesSary that the oreaSe ndeS and Shear Tnelnbers be pfoperly positioned hoightWi5e, WidthWise and lengthWiSe in the Tnaohino, ano alSo tht the Sheaf Inen1befS, hioh becon1e oTn, and the orease nderS which it Tnay be deSied to change to aCoofnn1odate diffeTen typeS of Work, be feod ily replaceable. t iS, thereforo, an objeot of thiS invention fo pfovide a 11ohine ofganization whiCh peTInit5 Such heightWiSe, iClth iSe and lengthvise adjuStnentS of the Shear n^ielnbefS and oTeaSe ndeTS, and a1so facilitateS the Te p1aoen1ent of theSe elenlentS- hUS in aooord anoe With a fufthef featoTe of the inx ention, the shear Inen1bers and oreaSe ndeS afe n1oUnted in fen1ovable headS Suppofted on oarriefS Whioh are arranged fo have hefghtWiSe, 1engthWiSe, ond idthfviSe adjusting novenentS.

v It iS propoSed to enoploy Shear TnelT1bers which fetraot to pfo de oleafanoe for dfiving faSten ingS, aS in the n1aohine of the Blanohafd patent above referfed to and it iS also pfopoSed to pro vide welt-Suppofting ofease nderS Whioh TIlay be TetTacted to prevent diSfigLlration of the upper engaging SI1rface of the vvelt dllring the inSean1 fiattening opefotion. vVith the above obieotS in vievv, a fuTther featufe of the invention oonsiSts in the pfovisfon of a member in whioh both the Shear nlelnber and the orease nder are n1oInted for operative Tnovenfent Telatively to Said ne1nbSr oZidtf1ff iSe of the Shoe.

n the Inanufacture of Goodyear ve1f Shoes there is a tendenoy fol' t11e end poftionS of the fnseaIn to Wofk ontWaTdly tOWafd the edge of the shoe bottoIn and vVhen this ooo11rS the outsole Stitoher often ndS it necesSary to oarry the olltsean1 outWardly in the Tegion of the endS of the inSeaTn in ordef to avoid the inSeonx stitcheS, and in doi1g So the outsean1 is soIZetiTneS oarfied o11tWardly too fa1' and part of ft iS otlt aWay in the trin1fning of the sole maTgin. t iS, therefore, an object of the preSent invention to work the end portions of the inSeaIn inWafdly befofe the Welted InargiI1 is Seoured to the insole. In the i1111strated n19dohine, Suoh inWard ITging of the inSean1 is effected by engagfng the Welt betWeen gripper Inen1befS Which grip Substantia1 extent of the vidth of the Welt and Inoving Said neIn bers in afd1y togethef toWard the centef of the shoe bottoIn The illuStfated gTipper Tnen1berS are the vvelt Suppofting creaSe ndefS and n1eTn bers thTough vvhich fastenings aTe driven to seo11re the Welted Tnargin to the inSole.

T'o augn1ent fhe invard IT1oveInent of the end poTtionS of the inSeaTn and to flaften the end portionS of the inseaJm subStaToe, thereby to pfo vide a sn1ooth and even Shoe bottoTn in the region of the heel bfeaSt line, there iS pfovided, in ao oordance vVith a fuTthef featuTe of the invention, IneanS oonstructed and arTanged to opeTate againSt the n1en1bers thTough vvflioh the faSten ingS are driven to pound Said n1en1bers againSt the Shoe bottoIn. AS hefein iHuStTated, the direo tion of the ou ndin action iS downWardl tovard the Shoe bottom and WidthWiSe of the Shoe towafd the centeT of the Shoe bottoIn, thereby bending the end portionS of the inSeaIn SubStance i1XvardJy againSt the insole.

t iS a fuftheT object of the invention to Seoure the welted rnafgin in the Tegion of the welt buttS to the inSole by IneanS of 9J p111rality of faSteningS vhioh Inay be dTiveI1in different poSitionS Width WiSe of the Shoe bottom in order to obtain the TI1oSt effective attachInent of the llppef and the vVelt to the inSole. vith thiS objeot in viev a, fufther featufe of the invention consistS in the pfoviSion of a plufality of fastening dfiving actuatofS and IneanS for operating the actuatofS oonlpriSing a dfiven S1ide whioh iS opefatively conneoted fo one of said actuatofS `vhich, in turn, is opefatively connected to the Othef aotuato1, Said connectionS being oonStructed and arranged to peTn1it individua1 adjustznent of the actuators idthwise of the Shoe, It iS to be underStood that the utility of this feature of the invention is not liInited to welt butting Inachines.

In maohineS having tack d1iving Inechanism the fe1T1oval of taokS Which becoTne fouled in the taok pocketS iS o source of annoyance to the op eTatoT and it iS an objeot of the preSent inven tion to n1ake it eaSier fof the operator to reInove fooled tacks Aocordingly, another featufe of the invention consists i1 the proviSion in a Shoe Tna chine provided vvith tack dTiving InechaniSTn, of taok-holding membefs Which by their engage n1ent vith eaoh other provide a pooket foT ho1d ing a taok for the driving operation, one of which IneTnberS is readily accessible, and IneanS for moving said nlember froIn its tack holding poSition to ex oSe a tack in safd pooket and to peTn)it the took to be ren1oved fTon1 the rnachine. In the iH11StTated n1achine the Tneans for Tnoving said Inen1ber iS a handle extending ffoTn the tack dJ'ivef guide into a position in vf1ich it is eaSily feaohed for nlanipulation by the operator.

n order to reTnove the shoe f1,oIT1 the nlachine dufing the interva1 betWeen the fetTaction of the operating parts and theif return to their initia1 poSitions, an ejeotol' engageS the Shoe and lnoves it away frorn the o erating artS of the Tnachine. The IneTnber for ejecting the Shoe alSo operates du1 ing the welt butting operation to hold the Shoe against n1oveInent in the djreotion of the vvelt butting cut- The iHuStrated ejeotoI iS n1ovable vvith the shoe lengthWiSe thereof aS the Shoe is bfought into poSition to be operoted upon and is arrested to position the shoe for thE Welt butting operation by an adjuStable abut- Iont. The illuStrated ejeotor operateS to ren1ove the Shoe ffon1 the Inachine dufing the intefva after the sheer n1eTnberS have been Tetracted and before they are fetufned to their initial position T'heSe and other featureS of the invention Wi1 now be desoTibed fvith reference to the aocoInpanying draWingS and Will be poinfed out in thE appended olaimS.
