8 Claims. (01. 12146) This invention relates to methods of preparing drawing and will be pointed out in the appended pre-welted uppers, that is, uppers in the manuclaims. facture of which a welt is stitched to the over- Referring to the drawing, a pre-wel'ted upper 2 lasting margin before the upper is lasted. which has not been mounted on a last is arranged Pre-welted uppers areusually lasted by means in inverted position for operation thereon by a 5 engaging the upper between the upper-attaching machine herein illustrated as a machine for apface of the welt and the outer face of the overplying cement to upper parts such, for example, lasting margin said region beingcommonly reas the sole-attaching face of the welt of aweferred to as the welt crease. For example,- it is welted upper. The upper is supported by the opa usual practice to last pre-welted uppers in bed erator and the welt is positioned between a suplasting machines by means of lasting'wipers conporting roll 4 which, as herein illustrated, engages structed and arranged to engage the upper within the upper-attaching face of the welt and the adthe welt crease. Pre-welted uppers usually come jacent surface of the upper, and a roll 6 which to the lasting operation with the welt held close is illustrated in engagement with the sole-atf to the upper throughout its entire width by the taching face of the welt. The roll 6 is knurled seam uniting the; welt and upper and the lastfor the reception of cement which is delivered ing machine operator is required to bend. the welt thereto from a trough 8 by a roll H] which dips away from the upper before he can last the shoe. into the cement in said trough and a roll l2 be- This is a difiicult and tedious operation and tween the rolls6 and ID. The supporting roll 4 greatly retards the production of the lasting mais mounted on an arm [3 which swings to move chine operator. the roll 4 toward the cement-applying roll 6.

It is anobject of the present invention to pre- In practicing the method of the present invenpare pre-welted uppers for the operations subse tioh the welt l4 of the pre-welted upper 2 is quent to the Welt-Stitching Operation, a11d p positioned with its upper-attaching face against ticularly for the lasting operation, thereby to the peripheral face of the supporting roll 4 and ake t u s y O theilasting machine D- the adjacent surface of the upper against one erator to prepare the welted margin of th 1 side of said roll. The roll 4 is then moved upper fo e lasimg Operation With this in View wardly to press the sole-attaching face of the welt the invention, in oneasp'ect thereof, comprises against the cement app1ying roll 5 whereupon stitching a-welt to the overlasting margin of an Said rolls are rotated to transfe the point f upper which has not been munted on a last eration progressively about the welted margin of thereafter, before operating on the overlasting the lumen AS the point of Operation progresses margin to arrange the welt for the reception of about the ends of the upper the we1t engaging an Outsole, progresslvely: bendmg, the Welt rolls cause the welt to project outwardly from the wardly from the overlasting margin of the upper margin of the upper and in so doing they cause and simultaneously applying pressure to the welt the outer margin of the welt to lengthen or 31 9 cause fi i fi i i longeg stretch somewhat and a substantial amount of an 1 5 Inner margm e ou War y curve the lengthening of the outer margin of the welt portions of the upper.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is: v

1. That method of preparing pre-welted uppers which consists in. stitching a welt to the overlasting margin of an upper which has not been mounted on a last and thereafter, before operating on the welted margin to arrange the welt for the reception of an outsole, progressively bending the welt outwardly from the overlasting margin of the upper and simultaneously applying pressure to the welt thereby to cause its outer margin to be longer than its inner margin at the outwardly curved portions of the upper.

2.. That method of preparing pre-welted uppers which consists in stitching a welt to the overlasting margin of an upper which has not been mounted on alast and thereafter, before operating on the overlasting margin to arrange the welt for the reception of an outsole, proressively bending the welt outwardly from the everlasting margin of the upper and simultaneously applying adhesive to the sole-attaching face of .the welt.

3. That method of preparing a pre-welted upper before the upper is mounted on a last which consists in applying rolling pressure simultaneously to the outer surface of the welted margin of the upper and the, upper-attaching face of the welt thereby to cause the welt to project outwardly from the upper,

4. That method of preparing .a pre-welted upper which consists in progressively operating on the Welt before the upper is lasted by means including a roll constructed and arranged to engage and press against the welt thereby to cause the outer-margin of the welt at the curved portions of the upper to be longer than the corre-' sponding portions of the inner margin 'of the welt.

ranged to engage, respectively, the upper-attaching face and the sole-attaching face of the welt and to bend the welt outwardly from the margin of the upper, and simultaneously applying adhe- ,sive to the sole-attaching face of the welt.

'7. That method of preparing a pre-welted upper before the upper is lasted for the attachment of a sole to the welt which comprises progressively operating on the welt by means of rolls constructed and arranged to engage, respectively, the upper-attaching face and the sole-attaching face of the welt, and moving the rolls toward each other to press the welt therebetween and to stretch the outer margin'of the Welt at the ends of the upper thereby to cause the welt at the ends of the upper to project outwardly from the margin of the upper.

8. That method of preparing a pre-welted upper for the attachment of a sole to the welt which comprises progressively operating on the welt by means of rolls constructed and arranged to engage, respectively, the upper-attaching face and the sole-attaching face of the welt, moving the rolls toward each other to press the welt therebetween and to stretch the outer margin of the welt at the ends of the upper thereby to cause the welt at the ends of the upper to project outwardly fromthe margin of the upper, and applying cement to the sole-attaching face of the welt by means of the roll which engages said face.

I JOSEPH FAUSSE.
