MACHINE FOR SHAPING UP'ERS.
Application filed July 10, 1922. Serial No. 573,801.
This nvention relates to machines for use in the nianutactiu'e o'i boots and shoes and more l'iarticularly, in many oitl its important aspects, to machines for shaping` the1 upper materials over a form or last. The invention is herein illustrated in its application to the lastin` of the heel end portion of a 'type ot shoe in which the upper in the lastingI operation is tastened to the insole by adhesion, but .it Will be recognized that in many 01" its 'novel features the invention is notlimited to the i'nanut'acture o't" that particular type ot shoe nor to the lasting o'l:I the heel ends ot shoes.
Shoes in which the upper is 'liastencd to the insole by adhesion, ot which tennis'shoes or sueakers are well known einunples, are corninonly made with an insole ot' rubber coluposition which is con'iparativey soft and tlexible and upon which the margin of the upper, usuallycoated with cement, :is pressed to fasten the 'upper in iasted position. ln the development ot machinery or lastinp,` this type ot shoe, in place of the hand labor employed hereto'tfore, special precautions have been necessary to avoid displaceinent ot the insole in laying the inargin of the upper inwardly over its bot-tom :tace and to avoid pre'inature adhcrence ot the inargin of the upper toitheinsole. lt has accordingly been proposed to utilize overlaying means operatinn' in a plane aii'ording ample clearance between it and 'the insole in the operation ot bendin` or laying the margin of the upper inu'ardly. To nsure the proper i relation between the overlay'ing means and the shoe in operation' upon difi'erent shoes, the present invention provides, as an 'important feature, novel means 'for determining by eugageinent With the shoe the relation between the overlayinfe` means and the plane of the shoe bottom. In its embodiment o'tf this feature in coi'nbination `With heel en'ibracing wipers, 'the machine herein shown has a gaging device 'which by engageinent With the bottoni ot .the shoe liniits preliminary positioning` movenient of the wipers heightwise ot' the shoe and determines the plaue ot operation o't the wipers substa'n'tially throughout 'their overlaying moveinent. lt is a turther advantageous charactei'stic ot the construction shown tha't 'the gaging device is arranged to serve as a holddown relatively to which the Wipers are advanced lengthwise of the shoe, to assist in preventing displacement of the insole by the action of the wipers. i
ln combination With nieansfor engaging the shoe to determine the relation between overlaymg means and the plane of the shoe bottoin, in an organization having means for el'i'ecting relative niovenient of the` overlay- Eng means and the shoe to press the inargin ot the upper upon the insole, the invention provides, as a furtl'ier important feature, means tor renderin` the shoe engaging means inoperative to prevent such' relative pressing movement. For the purpose in view the machine herein sho'wn has controlimg.mechanisn'i which is automatically operative to release the Wipers from thegaging device in time relation to their inward moveinent, 'thusfreeing' the wipers' for downward movement to press the margin of the upper into adl'iering relation to the insole.
sists in a novel construction and arrangenient ot xvper controlling means `permitting the wipers to adjust thernselves to the shoe in response to resistance of the shoe materials, the construction illustrated coinprising spring plungers arranged to aet on opposite sides of the Wiper 'holder in direct-ions substantially parallel to the plane 'of the wipers to centralize the Wipers normally in respect to tipping moveinent laterally of the shoe While 'pern'iitting thein to tip in one direction or the other to equalize the pressure on opposite sides of'the heel end of the insole.A i i In accordance with a further 'feature the iuvention provides a novel organization of end -ni'ibracing` wipers and a fiexible apron to transmit the pressure ot the Wipers to the shoc materials, the construction shown comprising` an apron arranged in novel relation to a heel embraeing band andV Wipers, to- Ward which the shoe is inovable to position it 'for the heel end lasting operation, and including,` novel supporting and controlling means .tor the apron.
The above and other features of the invention, including a novel construction of shoe end clainping inechanisn'i, and various details of construction and combinations of 'turther 'feature of the invention conparts, will now he more particnlarly described by reference to the aeconipanying drawings and pointed out in the claims.

The machine compriscs a base 2 on which is mounted a head casting 4 which supports the wipers, the heel band, and their operating and controlling mechanisms. Pivoted at on the base Q is a shoe support or jack comprisine' a standard 8 provided with an eyehar 10 for Supporting' loosel7 the lower end of a rod 12 on which is monntcd tor Vertical adjusttment a tubular member 14. Mounted for Vertical adjnstment. in the upper end ot' the member 14: is a bar 16 provided With a pin 18 to engage in the spindle hole ot a last and having ratchct teeth arranged to be engaged by a springr pressed pawl 20 on the member 14; to hold the heel pin in adjusted position. Clamped to the member 14; is a toe rest standard 22. and pivotally mounted at 24 on this standard is a toe rest holder 26 provided with an npwardly extending shank portion 28 on which is slidably mounted a toe rest member 30. rFhe member 30 carries a pin 32 which enters a groove in the shank 28 to prevent the member from turning. and also earries a spring pre ld paw] 34- for engagement with ratchett'eet'h on the shank 28 to hold the member in adjusted position. The holder 26 carries a detent 8G tor engagement with teeth 38 on the standard Q0 to hold the toe rest in any position to which it. may be adjusted by tnrning it about its axis Q1.. The heel pin and the toe rest may thus be adjusted upwardly or downwardly, each independently of the other1 to position any style or size of shoe in the correct relation to the wipers, and the toe rest ma3Y also be adjuSt/ed to aceommodate it to ditl`erent lengtha of shoes.
The tubular member l't extends upwardly between spaeed ears 4:0 on the standard 8 and has secured thereon a collar 42 engaged on its front face by the inner end ot a screw -t-t which is threaded in a bracket seeured to the ears -10 and is operated by a hand wl'ieel L10 to swing the member 14; and the part-s which are carried thereby rearwardly to Ward the heel band, or to permit them to be swung forwardly by the action ol' a spring;- plungrer 4-8 which is carried by the collar 12 and enzcfagesl a part ot the standard Since the standard 8 is locked invariabl)v in the same operative position, as more fully ex' plained hereinatter, this adjnstment serves to determine the lengthwise position of.tlu'v shoe in operatire relation to both the heel band and the wipers. This jack ali'ords conrenient and readily adjustable means tor presenting the shoe in proper relation to the operating instrumentalities. but, it will be recognized that in many of its novel aspects the invention is not dependent upon the use ot the particular jack illustrat'cd.

The jack is int'cndr'd to bo sw'nng real-- wardly about its pirot (3 by the operator. to carr)` the shoe into tlu` heel band and to ion sipply the band tothe shoe as above de' scrihed, and the machine is provided with means which is operative in response to such renrwzn'd` in(\"e1nent of the jack to lock the jack in operntive position. For this purpose there is inounted in bezirings in 'the bzise 2 :i trzinsverse rock shoft 741 upon which secured zi looking;` ineinber or leyer 76 having' :i liool; sheped front end to engnge a pin or roll 78 on the jzicl: stnndz'ird 8. On its ren r end the lcver '76 hns :i tooth 80 nrrnnged to be enp'uged by a lzitch 82 on the 'lower end of :i rod 84: for holding` the lever initielly in idlel position. The rod 84 is pivotcd :it its upper end to one orin of n. bell-crzink level S :nid is connected to :1 spring` SS which tends to pull the rod upwnrdly find nilsoto hold it forwardly in position for the letch 82 to cngagc the tooth 80. On the lower end of tholutch is :i finger 90 in position to be engng'ed by the rcar end of ;i rod 02 which is pivote'lly connected at its front end to the jack standard 8. Then the jziek is n'ioved rczirwnrdly by 'lie operator tht` rod 92 pushes the lntch out of engug'cinent with the tooth 80 as .soon ns the roll TS is in position to bc locked by the leVer 70, :md the lever then swung into lot-king` position by n torsion spring; 9%. The bell crnnk 8G is controlled by a, (fani Dtiinounted on n Cain sheft 98 through which operzitive inoveinents fire inilfierted to the lasting instrunieutiilities :is hereinztfter described, und in lthe course of the o x'cle of Operations the czun perinits the spring 88 to rnise the rod 84 until its latch 82 again connects with the lever T0.

For 'laying the margin of the upper over the heel end of the insole the machine 'is provided with hcel en|brzicing wipers l0t which :irc inounted to swing` about .spzniied pivot stnds 100 4) on a wipcr holder 108q the wiper holder being` mount- `lnl niovcment in a, guidewuy 1;. 5) forined in a wiper cnrrier i is provided at its front and rcnr (Fi whicl ends with cars slidobly inounted on horizon rods 114- fnst on the head 11. Forward biicltwerd inovenients are iinpzirted to the carrier 112 by n path ceni 116 which cnlriie'cs :i roll 118 on the rziirrier. The roll 112 iff; i'nou ted on :i block 120 which is ndiustnhie l' nienns of :i screw 122 `and a hand wheel l' on the cerrier 112 to Very the iiinit ot hirwnrd inoyenient of the' wipers. As the wipers are advanced by the wiper (zirrier they :nie closed inwirdly nt the sides of the heel end of the shoe by pins 120 in enkiziie'ement with inwzirdly inclined surfaces 128 'torined on rearwurd cxtensions of the wipers. A spring 130 connectin'g the rear Ward extensions of the wipers holds them against the pins end opens the wipers upon bnclt'wnrd inovcnient of the carrier. The pins 126 .fire curried by blocks 132 which :irc inoyzihlc lnternlly of the shoe in guide' wziys forincd in n supportiire` block 134, the l loel s12 being' :idjustable townrd and from cech other by means of a rightl and left screw 136 to vziry the limit of closing inovenient of the wiiiiers zindthe distiince between theni before they begin to close. lThe block 84 which czn'ries the blocks 132`is adjust- .'ihlc lengthwisc of. the shoe to vury the time in the forwnrd niovenient of the wipers when they begin to close. The rezirwerd extensions of the wipers :tre slotted to einbrnce the edge of a platel fast on the wiper holder 108 to :issist in stcadying the wipers` in their action upon 'the shoe n'mterinlsL In the construction shown the wipers do not opernftc in direct engngcincnt with the upper materials, but through u fiexible :ipronV 1110, which inny be inndeof leather or i'ubber or other suitable inutcrizil end is nrranged to enibruce the heel end of the shoe inside of' the heel bnnd and to extend upwurd across the edges of the wipers. The apron is secured to the band byiclanips 142 which urc tightcned by nuts 141, and et its upper end it is connected to Springs 1-16 which hold it up across the edges of the wipers while perniitting it to yield in response to inward pressure of the wipers. By the use of the licxiblc npron the nnirgin of the upper is g'zithered uniforn'ily about the end of the shoe :ind is drawn tigl'itly inwzird over the edge of the insole without the necessity of 'Operating Athe wipers as close to the plane of the insole ns would be required if the wipers directly eng'uged the upper materials, and in this wziy also further assurance is nfforded that the insole will not be wrinkled 01' displziced by the pressure of the wipers.
To insure that the wipers shall be advanced and closed in the dcsired relation to the plane of the shoe bottoin in Operating on different shoes, the machine is provided with inezins for deterininfng' by engageinent with each shoe the height of the wipers relatively to the plnne of the insole. As hereinhefore explziined, the wiper holder 108 is vertically niovnble in guidewziys 110 in theV wiper corrier 112, and the wiper holder is initially po' sitioned nt a higher elevzition than in the operntive inoveinent of the wipers by means of ;i lerer 1118 which carries zi roll 150 positioned beneeth :rrerwzirdly extending` portion of the wiper holder nnd has on its rear end zi roll 152 Controlled by a. ceni 154 on the cznn shnft 08. `lfnnnediately upon the starting of the machine the leverl141-8 is released by the ruin 1541-, and the wiper holder 'with the wipers is then inoved downwurdly by its own weight v:issisted by :i plunger 156 lift) :md a light Spring 158 on the carrier 112. The limit. of `such downwarcl niovement ot? the wipers is deterinined by a, holcldown foot which is nioved (lownwardly by the lever 148 until it ene'ages the hottoin face of the heel end ot the insole. the holddown deterniinine' h): such engageinent the lfniit ot' nioveinent of the lever and the wiper holder. ly reference to Figs. and 7 it' will he seen that the holddown 'l'oot'` 100 (':n'ried h t rod 102l whieh is mounted in :i vert'ical guideway Vforined in a slide 101, the lnt'ter hein;r inounted for vertital nmveinent in a ln'aeliet 100 secnred to the stationar): rods 114. The rotl 102 is norinally held 'from vertieal movenient in the `slide 101- hj a pin 108 whieh is pres:el hv a spring` 170 into a hole tormed in the side of the rod. lvlovahle vertit'ally with the slide 161 ie a har 172 the lower end of which is not'elied to receive a hloch' 174- (FQ. 41) pivoted on the front end otI the lever 1218. lt will thnf:v he :seen that when the lever 118 is released so that itis 'front end is :strong downward it 'nrries with itV the har 172 :ind the .slide 104- :in'l that' the holddown l'oot.1tj0lin|its such movenient' by engageinent with the shoe. therehy deterinininQ` the heizht of the wipers in their advaneine' end elosing nioveuients. ln order to very or :'.djufit' the heie'ht ot the wiperjs the ::lide 1011 ni: he vert'ieally adrinnted relativelv to the har 17:1 hy a screv-f 170 which is threaded n the slide and enzages flanges on the upper end ot the har. 11v reference to Figzs. 2 und it will he seen that the holddown 'foot' has an upwartlly extending shanli portion with a .spherical end niount'ed in a eo-i'let iu the lower end ot the z'oti 102 and held in the ."oclcet h v opposite lea'l' tsprine's 178. so tlnit` the nieniher 100 may t'p as required to feat t squarelv upon the insole.

For this purpose the slide 1(3-'1- has pivoted thereon an :ii'in 15-10 (Fin. T) provided with a ting'er twhif'h engzae'es in a ret'ez's in the .side ot' the pin ltt. The wiper (':iri'ier 11:! near the en-:l ot its forward niovenicnt ene'ae'es the :n'n 180 and operates it` to v'xithdraw the. pin :t'roiu the hole in the rod 102. This renders the hohldown inell'eetive to preventi turther downward inm'einent ot' the vipers. since the holddown is then Controlled simply by :1 lght'y nprinT 181 provided 'tor retnrning it subsequently to its initial position in the slide 10z. Then the pin 168 is withdmwn to release the rod 162 it serves by engageinent in a slot 186 in the rod to prevent the rod Vt'roni turning. VVhen the wiper holder s thus released, t'urther downward movenienti is iniparted to it through a eompzi 'atively heavy spring 188 which h'ars on the upper end of the plunger 150 and is eoin' pressed h j a collar 190 which hears on the upper end m the springr and is fast; on :i rod 1512. l)o\\'nward moveinent is iinparted to the rod 1512 l v a lever 191 provided With a nlideway :to u hloek 100 in whfch the upper end of the rod if; seated. The lever 101 is last on a rock shal't 1518 which earries an arin 200 provided with a roll engagzed by un operating cam *302 on the :zim shat't. Nnn' the end ot the elvcle the level' 148 is returnel hy the cam 1:71. thus lifting the vipers and the lmlddown. and upon rel mse ot' the lever ai'in 180 the pin 108 .snaps linek into position to lock the holddown again to the slide 104. ly rel'erenee to Fiji.

'1`he elutch is controlled hy u lit) clutoh rod` 210 to which movement is imported to start the machine by a treadle 212.
In the use of the machine the operator mounts the last With its upper upon the shoe support, and after positioning the hcel end portion of the upper with its inargin projecting the proper distance above the heel seat face of the last, svl'ings the shoe support rczu'w-n'dly to carry the shoe into the .heel band, the letter being' mrnpped about the heel end ofithe shoe by the pressure of the shoe agg'ainst it. in response to such rearward movement of the shoe support the lever 'T6 is released and locks the support against return forward moveinent. The operator then places an insole upon the bottom of the last in proper lengthwise position determincifl by pressin;` it bacl; against the upstandingil inarggin of the h-eel end of the upper. He then depresses the treadle and starts the machine. li'nn'lediately upon the starting of the machine the lever M8 is released by its cam, and the wipers 10eland the holddmvn foot 100 are moved downwa'rd to positions determined by engagement of the' holddown with the bottom face of the insole. The wipers are then advanced and closed and 'art through the tlexible apron 140 to gather the mz'irgin of the upper about the heel end of the last and to lay it iniv'firdly over the insole, the holddown foot 160 assisting by its downn'ord pressure in preventing displacement of the insole by the action of the wipers. Netii' the end of the advancing and closing mov-ements of the wipers the n'iper carrier engages the iirm 180 and brealis the operative connection between the holddowin foot and the Wiper holder. The lever 10-1 is then operated by its camuto force the Wiper holder downvvard and through the comparatively heavy spring 1.88 to press the n'iargin of the upper [irmly into adhoring relation to the insole, the wiper holder tipping latera-lly of theshoe as may he required to eqnalize the pressure at opposite sides of the shoe bottom. Follovving' these Operations, the parts of the machine are returned to their starting positions, the shoe support beinov released by its looking means to pcrmit it to swing' forwardly into convenient position for the operator to remove the shoe.
