Serial No. 212,999.

" trated in application to means for lasting the toe ends'of shoes, although in its more general aspects it is not limited to toe-lasting Rmeans. An importantobject is to provide 1 proved means for lasting shoes of a'type in 15 which the upper is fastened to the insole in the lasting operation'by cement, commonly known as tennis shoes or sneakers; and the invention is herein shown as applied to a tennis shoe lasting machine of the same eneral character as disclosed in my earlier ".tion Serial No. 58,9 i4l, filed on Sep- 25, 1925. it is to be understood, owever, that the invention is not limited in utility to means for lasting shoes of that ticular type nor to a machine organizaf the particular character illustrated in olication. V

insuring that portions of the ing the margin of the insole down upon the bottom of the last, in locations substantially at the ends of the wipers, i. e., at those portions of thev wipers that are farthest from the end face of the shoe. Preferably this overlaying or folding means is arranged to begin its overlaying action before the portions of the wipers adjacent thereto begin to wipe the upper inwardly over the insole, thus insuring that portions of the insole along the sides of the end portion of the shoe will not be so positioned as to be displaced by the wiping action ofthe wipers. The novel construction herein illustrated for accomplishing the ob jects in view comprises flexible lasting straps connected to the ends of the wipers and operated thereby to lay the upper over the insole,

the straps being so disposed in relation to adforrendering the lasting straps effective to.

wipe the upper'heightwise of the last, i. e., to perform an upwiping operation thereon, prior to their overlaying action. V

y The invention will now be more particular ly described by reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 1 is a plan view of toe-lasting mechanism of the same general character as that disclosed in my earlier application, with the present invention embodied therein, a portion of the structure being broken away to show underlying parts more clearly; Fi 2 is a view in end elevation of the mechanism shown in Fig. 1, with parts in section Fig. 3 is a view similar to a portion of Fig. 2, illustrating the positions of the parts at the end of thc'toe-lasting operation;

Fig. 4 is a plan view illustrating the positions of the parts at an earlier stage in the lasting operation; and

Fig. 5 is a view in elevation, further illustrating the action. of the lasting straps at that time in the lasting operation indicated by Fig. 4.

Since the general organization and manner 7 of operation of the machine to which the pres ent invention is herein shown as applied are fully disclosed in the earlier application, only such parts of the machine as it is necessary.

to refer to for an understanding of the invention will be described in detail. It will be understood that the last with shoe materials comprising an insole a and an upper b thereon is mounted on a shoe support (not shown) with its toe end portion positioned'upon a toe.

rest 10 which has a depending hollow stem 12 slidingly mounted in a holder 14:. The toe rest 10 is depressible by the shoe against the resistance of a spring 16, within the hollow restis effected bymeansincluding a presser v as ' foot which engages the insole centrally at the toe end of the last, and as the shoe isforced downwardly the upper about the toe of the last is engaged and wiped upwardly toward the edge of the insole by a yieldable toe band 22 which embraces the toe end of the shoe. The presserfoot20 assists in holding the ins sole in proper position on the last, and in addition tothe presserfoot, .there is provided a curved member 23 which engages the margin of the insole about the end portion of the toe and presses it closely against the bottom'of the last to prevent its displacement in that location in the overwiping operation;

After'the shoe has arrived at the end of its downward movement, the margin of the up per about the end and along the sides of the toe is gathered and wiped inwardly over the "insole by toe-last ng. wipers which, in the con- 7 struct on shown, comprise a pair of endwiper plates 24 having wiping edges curved to embrace the upper about the end portion of the toe and a pair of side wiper plates 26 which arearranged to act only at the sides of the toe. The wipers 2a are mounted for'move ments in a curved guideway 28 about an axis extending heightwise of the shoeand located centrally of the toe, theguideway 28 being formed in a wiper carrier 30 mounted for movement lengthwise of the shoe in a holder or casing 32. The wiper plates 24 thus have advancing'movement lengthwise of the shoe and closing movements laterally of the shoe.

The side wiper plates 26, on the other hand,

are, mounted for swinging orelosing movements laterally of the shoe Wltl'lOllt advancing movement,"be1ng pivoted at 34 on the casing 82 to swing aboutaxes extending heightlengthwise of eration.

plates, there are provided gear sectors 38 which are pivotally mounted on the casing 32 and are connected by links 40 to bllG' WlPQIS 24:; Each of the gear sectors 38 iso'perated by a rack memb r $2 to which operative movementis imparted by the rock shaft 36 through connections also more fully disclosed in the earlier application. It will thus be seen that in the movement of the rock'shaft 36 to advance the end wiper 2dthe' gear sectors 38 7 also areoperated by the rock shaft to impart closing movement-s te these wipers. Closing movements are at the same time imparted to tne side wipers 26 by the gear sectors 38 through rolls 4 lwhich aremountedon the gear sectors and engage the outer edges of the wipers 26, the return movements of these wipers being effected by rolls (not shown) which are mount d on stnds i-S that connect the links 40 to the wipers 24 and engage upraised portions 48 of the wiper members 26. Since theside wipers 26 move only in direcions laterally of the shoe, the construction provided serves to avoidundue bendingof the margin of the upper at the sidessof the toe The construction thus fardescribed issub the shoe in'thetoe-lasting op stantially like what is shown in the earlier application. For purposes'of'this invention there are provided at the rear ends or the toelasting wi'aers flerriblelasting straps {50 which, i s

in the construction shown, are connected to the side wiper plates 26 and are operated;

thereby to lay or fold the margin of the upper inwardly over the insole without any substantial wiping action thereon through the upper to press the of'the insole 1n those locations upon the bottom of the last, the

arrangement being such that the straps begin their overlaying and pressing action before the wipers 26 adjacent to the strapsbegin to wipe the upper inwardly, over the insole, as will be evidentby reference to The straps '50, which may be made of leather or other su table material.

members 26 and are received in recesses 54- inthesemembers as the latterare move n;

:wardly toward the shoe. As their upper ends 7 are controlled by upraisod portions 52 on the ends of the wiper the straps are connected to. slides56 which are mounted for movementslaterally of the shoe in the upraisedportions of the wipers relatively to the straps.

To assist in preventing thestraps 5Q from having any overwiping action at the time of the operative movement of the wipers, they are fastened at their lower ends to holders 60 by the action of which they arepressed against the sides of the shoe. These holders are pivotally mounted at 62 on the upper ends of carriers ea provided with depend:

ing shanks 66 which are swiveled in arms 68 for movement about axes extending height wise of the shoe to permit the holders 60 to adapt themselves to the contour of the shoe. The arms'tiS are pivoted at 70 on plates 72 which are secured to a stationary bracket 74.

A spring 76'connected to the opposite arms 68 tends to swing these arms and the lower the latter is depressed. i iccoroingly, in the the overwipingoperation the lower straps which are in engagement witu downward movement ot the shoe, the straps 50 serves to wipe the upper upwardly toward the edge of the insole and thus to tighten it over the last across theiorepart, simultaneously wit-lithe upward wiping action of the toe band 22 in front of the straps. In this upwiping action of the straps their holders 60 are spread apart against. resistance of the spr ngi76, will be'ev oent by reference to S and thereafter the straps are aressed 2 v e v p by their holders against the sides oi the shoe to holdthe upper inits upwiped condition,

while they are held against overwiping action'on the upper in the operative movement the wipers.

It will be understood that at the time of the overwiping movement oi the wipers the Y i p means, including the presser foot in a position in which theinsole is spaced somewh t beneath a the lower faces of the wipers, to assist further in avoiding displacement oi any portion of the margin of the insole infthe overwiping operation, as will be evident by reference to Fig. 5, and that after the wipers have completed their overwiping moven'ient 1 =0 shoe is'pressed upwardly in response to re movement of the depressing; mean cause the wipers to press the cement-coated ma? of the upper firmly upon the hotter. the insole, as fully disclosed the application. The recesses 54 in wl straps are received extend inwardl the wiper members 26, as'shown and'3, and are so arranger. that c L he o these wiper members and the 1 the-over- :races cl" laid margin of the upper are substantially in the same plane, so that the faces of the wipers and of the straps are both effective to press the upper firmly against the insole in the upward movement of the shoe toward the wipers. It will be further seen, by reference to Fig. 1, that portions of the straps 50 which are secured to the holders are wider than portions engaged by the wiper members 26, so that these widened portions serve to upwipe the upper in locations underneath portions of the margin of the upper that are engaged by the edges of the wipers'26, these widened portions of the straps serving virtually as extensions of the toe band 22.

' In the operation of the toe-lasting means, briefly summarized, the last with the upper and the insole thereon is forced downwardly by the action of the shoe-depressing means, including the presser foot 20, at a predetermined time in the cycle of the machine as a whole, as more fully disclosed in the earlier application. In this downward movement of the shoe the toe rest 10 is depressed against the resistance of its spring 16. and finally against the added resistance of the supplemental spring 18, and the toe band 22 and the lasting straps 5O serve to wipe the upper upwardly toward the edge of the insole, the strap holders 60 being swung apart against the resistance of the spring 76 by wedging action of the shoe thereon. Thereafter the toelasting wipers 24 and 26 are operated by the rock shaft 36 to wipe the upper about the toe inwardly over the insole, the side wipers 26 receiving only swinging movements laterally of the shoe, while the end wipers 2&- are both advanced lengthwise of the shoe and swung inwardly, portions of these wipers aovancing' over the upper faces of the wipers 26. As the side. wipers 26 receive their inward swinging movements, they carry the straps 50 inwardly over the margin of the insole without any wiping action on the upper, but with a folding action whereby they bend the margin of the upper inwardly over the edge of the insole and act through the upper to insure that the margin of the'insole at the rear ends of the wipers will be pressed down upon the bottom of he last without objectionable inward displacement from the edge of the last bottom. Since the straps are so positioned relatively to the edges of the wipers 26 that they being their overlaying and pressing action before the wipers begin to wipe the upper inwardly at the sides of the toe, as indicated by Figs. 4 and 5, insurance is aflorded that portions ofv the margin of the insole at the sides of the toe at the rear of the member 23 will not be in position to be displacedby the wipers. During the overwiping action of the wipers the straps are carried farther inwardly over the insole, the slides 56 being pulled inwardly along their guideways, and thereafter the shoe is pressed oveupwardly against thewipers and the straps by the action of means including the springs 16 and 18 to cement the margin of the upper firmly to the insole.
