This invention relates to the manufacture.

of shoes, and more particularly to the shaping of shoe upper materials (hereinafter referred to inclusively as the upper). The invention provides improvements in upper shaping machines, and in one aspect also an improved method for use in the shaping of uppers. In its mechanical aspects it is here-' in illustrated as applied to a machine for shaping or molding the toe end portion of the upper, off the last, over a metal form,

, upper,'nor to machines ior shaping the upper over a form of the character illustrated, as

distinguished from a difie'rent kind of form' such, for example, as a last.

In a machine of the type disclosed in the I above-mentioned Letters Patent the upper, is

presented by the operator in a definiterelation to the upper-shaping means by the use of a manually movable device or presenter the proper pos1t1on of which is determined by its engagement with; a portion of the machine;v

More particularly, as therein disclosed the presenter is provided with jig pins for engaging the upper in jig holesformedtherein at theopposite sides of the torepart, and its position .is determined by toe-embracing wipers with which the machine is provided for wiping the marginal portion of the upper inwardly over the form, the Wipers having slots that receive the jig pins. The present invention, in one important aspect, provides means for insuring that the presenter will be properly positioned prior to the upper-,

shaping operation. For the" purpose in view the machine herein shown has'means for engaging the presenter and for moving it to its proper position if'it' has not already been moved fully to that position by the operator; In the construction shown this meansisfop erated 'bya treadle which is also utilized to start the power-operationof the machine, the

treadle being effective to start'the "machine only after the presenter has been properly positioned. In, accordance with ,a further novel characteristic of the machine, the means for thus insuring that "the presenter will be in its proper position acts to main tain it in that position until after-the be'-' ginning of the operation of the machine upon i the upper.

The machine herein shown is further pro-- vided with novel means for withdrawing the, jig pins iroin the holes in the upper. As illustrated,this means comprises members that.

are first moved into positions to acton the presenter. in locations spaced from then-jig 4. pins and are then moved to withdraw the pins both from the holes in the upper and from the slots thewipe'rs, these movements being efi'ectedflinf automatically determined time relation to the operation of the machine upon the upper.

Machines of the type illustrated in the above-mentioned Letters Patent have been provided heretofore, with grippers arranged to" g to gripthe' margin of theup'per at the opposite sides of the toe over the outer faces oi the wipers and movable inwardly toward the" form while preventing uncontrolled shifting of the margin of the upperin theupper-shaping operation, as disclosed inLetters Patent No. 1,706,474, granted on'M'arch 26, 1929;,

uponfan application OfW CfBaXter and in' Letters Patent No. 1,711,946, granted on May v 7 ,1929, upon an earlier application of mine. To permitthe grippers to move inwardly toward'tlie form, they are mounted, as therein disclosed, on carriers, that swing about axes parallel to the plane of the wipers, the grip per jaws being movable in curved paths. 1 It is desirable that thegripperjaws bepositioned close to the wipers/in their operative movemerits, and especially thatfthey be so positioned when the upper is presented to the machine, so that its margin may be readily inserted between the aws. This invention accordlust-rated in substantially straight pathsy'in-v the upper-shaping operation. More jparticular'ly', the construction shown is such that.

in the machine and the corresponding'si-ze of the upper.

It is a further characteristic of the operation ofmachines of the type illustrated that themarginal portion of ftheupper is yieldinglyclamped to. assist in tensioningthe upper about :theform and to render the wipers more effective in, wiping its, marginal portion tightlyand smoothl inward over the form toprovide a flangea apted for attachment to. an insole. For that purpose such machines inchide clamp members which clamp the margin of theupperupon. theouter faces of the wipers whilepermitting it tosslip in response toth'epuxll of. the body of the upper thereon in. the upper-shaping operation, these members andthe.wipersthusserving as cooperatiligchrnp members. for, clamping ,the upper between them In another aspect the invention. provides. improvements in the upper clamping means, and asherein illustratedin: thelconstruetion and control: .of the; members that clamp the upper upon the wipers. In-

aecordance. with one. feature, thesev members are so formed thatwhile applying to the margjnalportion of the, uppersubstantial pressure. a; distance from the extreme edge of the upperearly intheupper-shaping operation, theyleaveportions nearer the edgewithout substantial pressure-thereon,although be.- inghpositioned .close enough. to these portions to. ppeventthe formation. of excessively prom.-

imnt wrinklestherein as the. margin of the upper. is drawn :inwardly. toward the form andf is, ironed Tout by the clamping. pressure. In accordance, with another feature, as herein illustrated, the. members that clamp the up- 4 per .OILthQ .wipers areso. controlled that, while lnitially retracted. outwardlyover thewipers,

they are, moved firstto positionsopposite the pottion-ofthe upper totbe clamped. and then m. .adirection" substantially perpendicular to A theupperrclamping faces ofjthewipers, so as to msure against displacement of the. upper asthey-are carried.intoengagement with it. ItwilLbe-evidentthat in these; features the inventionisnot limited with respect to the number. of. the cooperating. clamp members nor toa construction inwhich the wipers are apart ofjtheclampingmeans;

Inthe shaping over a formof the toe portionbfanupper whichincludes box. toe stiffen ng material. it is.- desirable that the stiffening material shall be in a very soft and pliable condition until the completion of the uppershaping operation. WVhere, as illustrated, the marginal portion of the upper is gathered and wiped inwardly over a orm to produce a flange adapted for attachment to an insole, it is especially desirable that the stiffening material in this portion of the upper shall be soft and pliable until the flange has been formed, in order to facilitate the shaping of the flange without the formation of any excessively prominent wrinkles in the gathered margin. It is also desirable that after the upper-shaping operation the stiffening material shall harden quickly. With these and other objects in View, the invention provides improvements in bothmethod and means for treating the marginal portion of the upper. In, accordance with one aspect of the novel method, as applied, for example, to the use ofstifi'ening material adapted to be softened by heat, .the margin of the upper is heated during. a portion, at least, of the operation of wiping it inwardly over the form to maintain the stiffening. material in a soft condition, after which the upper is maintained under pressure withoutthe application ofvheat so that the stiffening material will, quickly harden. This method is especially useful where, as illustrated, thehardening of the stiffening materialis depended upon to maintain the upper inits shaped or molded condition without the useof fastening means, since notonly is the shaping of theupper performed under the bestconditions in respect to the treatmentof thestiffening material, but therapid hardening of the material afterthe upper has been shaped is. also insured, so that the upper need remain under pressure for only a comparatively shorttime. To assist in the practice of the method, and in accordance with. a feature of the-invention, the members which clampthemargin of the upper on the wipers are maintained in a heated condition, these members, vas illustrated, remainin I in contact with more or less of the margin 0 the upper substantially throughout the operation ofwiping the margin inwardly over the formsand being then withdrawn to remove from the upper the source of'heat. It will be evident that in respect to the means for applying the heat the invention is not necessarily limited to aconstruction such as, shown in which the upper is clamped between wipers and cooperating heated clamp members.

Inga-further aspect the invention provides improvements in means for embracing an end of an upper and pressing it against a form,

the-means herein shown comprising a device forwiping the toe end portion of the upper heightwise. of the form. For the purposes in view this device, as illustrated, is so mounted astopermit it to movebodily both lengthwise and laterally of the form inresponseto pressure. of theupper and form against it,

andcoinprises also members that are rela-' tively movable laterally of the form in response to such pressure, so that the device adjusts itself to the upper and form while applyingelfective pressure all around the end ofthe upper. For controlling the relative movements of thedifferent members and the bodily movement ofthe device lengthwise of the form, a novel arrangement of spring mechanism is provided. In this part of the machine various novel features are to be recognized, as more particularly hereinafter explained, whether considered as means for wipingthe upper heightwise of the form or sure and automatic means ,for again starting the machine to releasethe pressure after a definite interval of time. This not only relieves the'operator of the necessity of starting the machine the second time, but also insures uniformity in the length of treatment of different uppers;

The above and other features of the invention, including also novel means for supporting the presenter, novel details of construction'of the presenter, and various other novel details and combinations of parts, will now be more particularly described by referencepointed out in theclaims.

In general similarity to the disclosure of the Letters Patent mentioned, the machine includes a metal toe form 20 detachably securedon a supporting arm 22 whichis mounted at 241 on the head of the machine for swinging movements in a vertical plane,-the form being so constructed as to mold the toe portion of the upper substantially to the shape desired for the finished shoe and, as herein illust'ated for purposes of welt shoe work, having a recess 26' extending around it into which the marginal portion of the upper is 3 wiped to shapeit so as to conform to the feather and the lip or rib of a welt shoe insole and to provide an upstanding flange for attachment to the lip or rib of the insole. The arm 22 is connected by a bar-28 and a rod 30 to a lever 32 controlled by a path cam formed in'one side of a cam wheel 33 (Fig. 2) mounted to turn on a shaft 34, whereby downward swinging movement is imparted positively to the form relatively to an upwiping device including a toe band 36 which embraces the upper about the toe and wipes it heightwise of the toe as the form is thus depressed. At the end of the downward movement of the form the marginal portion of the upper iswiped into the recess 26 of the form by toe-embracing wipers 38 carried by wiper holders 39, and the form is then moved yieldingly upward by reverse movement of tl e lever 32 to increase the downward pressure of the wipers on the upper, a spring being interposed between the end of the bar 28 and a collar 42 on the rod 30 to transmitthe force of the rod yie-ldingly to the bar in the upward movement of the parts, as more fully dis- ,closed in the prior Letters Patent. The

wipers 38 are advanced and closed inwardly over the form by mechanism including a toggle 42 connected by a link 44 to a lever 46 which is operated by a path can formed in ;one side of a cam wheel 48 on the shaft The upper is presented for the operation of the machine, as more particularly hereinafter described, with the margin of its toe-end por tion outspread over the outer or upper faces J of the wipers 38, and the marginal portion of the upper is clamped upon the wipers by clamp members 50 before the form 20 in its downward movement arrives in position to engage the upper. As the form is moved downwardly it presses portions of the upper against a toe rest which moves downwardly with it, this toe rest being mounted and controlled substantially as described in Let ters Patent No. 1,706,474.

For presenting the upper with its margin outspread over the wipers 38, the operator utilizes a portable presenter whereby the upper is positioned in a definitely determined relation to the upper-shaping instrumentali- ..ties in the same general manner as disclosed in Letters PatentNo. 1,692,284. In the con struction herein shown, as illustrated in Fig. 13,, the presenter comprises two rods 54 mounted in a cross-bar 56 to which is secured a handle 58, and on the outer ends of these rods are secured blocks 60 provided with extensions 62 on which are mounted jig pins 64 arranged to enter holes previously formed in the margin of the upper at the opposite sidesof the forepart. The presenter shown in Fig. 13 is intended for use with low-cut uppers, and has a bracket 66 fastened on the cross-bar 56 for supporting the rear end of the upper. For use with high uppers a downturned plate 68 is used in place of the bracket 66, as shown in Fig. 17. Each of the pins 64 has a ball-shaped end 70 below which is a port-ion 72 (Fig. 16) of reduced diameter, and the jig holes in the upper are of such sizethat theupper rests on a shoulder 74 a.

the upper end of the-larger portion of'eaclr pin in spaced relation to the extension 62-11nd is held against accidental displacement by-theballshaped end 70 which is v of somewhat:

larger diameter than the jig hole'inthe upper. The proper position of thepresenter in relation to the upper-shaping means is determined by the wipers 38 which are pro-- vided for this pu pose with slots 76 toreceivethe jig pins 64, these slots being somewhat differently shaped than heretofore. Asill'us trated in F 14, the portions'of the pins that enter the slots'are the larger portions below the shoulders 74, the extensions 620i" the blocks 60 lying below the wipers.

The machine herein shown is provided with means for insuring that the presenter will be properly positioned prior to theupper-shaping operation. prises two levers 7 8 arranged to engage the This means com blocks 60 on the presenter to'insure thatthe:

jig pins 64 will be located atthe inner ends of the slots 7 6 in the wipers and'to force them into those positions if they havenot already beenmoved fully to the ends of the-- slots by the operator. The levers-78 (Figs.

1 and. 2) are j ivotally mounted on the front" ends of forwardly extending levers 80 which are pivoted on studs 82 onthe frame of themachine and have rearwardly extending arms connected by rods 84 toarms 86' proecting rearwardly'from a sleeve 88 (Fig: 2)

which is mounted to turn about a rock shaft 90 supported by a holder 92 mountedom a cross-rod 93. The connection between" each arm 86 and the corresponding rod 84 isa yielding one, the arm having a'block 94* swivelcd on one side thereof toprovide a; hearing through which the rod extends. and a oted on the studs 82, and these bell-crank.

levers are connected to the arms 86 by rods 106 which extend through blocks 108 swiveled on the arms, springs 110 being mounted vetwcen the blocks and nuts 112 on the'ends of the rods. On each rod 106 is also secured a collar 114 to he engaged by the upper end* of the block 108. It will thus be seen that when the sleeve 88 is turned to swing the arms 86 in a downward direction, the levers- 78 are raised by their supporting levers 80 and are also swungabout their pivotal con-- ncctions with the lovers 80 by the bell-crank levers 104. The upward movements of the front ends of the levers 80 are limited. by'r stop-screws 116 (Fig. 2) on the frameof the machine, so that the upper ends of the levers 78 are carried from their initial positions, in which they are low enough notto interfere with the operators manipulation of the presenter, upward only to the same height as the blocks 60 on the presenter. The swinging movements or the levers 7 8, however,-con- 1 arms 86, and beforethese arms complete their tinue until their upper ends are carried rearwardly into. engagement with the blocks and f erce the iigi 'iins 64 to the ends otthe slots 76in the wipers if they are not already in these positions, as illustrated in Fig. 14. It will be understood that after the levers 8O engage the stop-screws 116, the springs 96 yield during the continuedmovements of the movements the springs 110 also are somewhat compressed For moving the'levers 78 as above described, the sleeve 88 is turned by theoperator by means of a treadle118 which is mounted on the base of themachine, and operates a crank arm 120 connected by a link 122 to an arm 124 on the sleeve 88; A torsion spring 126 serves to maintain the treadle' and the levers 78'normally inrtheir idle'positions. The treadle 118 is also utilized to start the power operation ofthe machine (the term machine being used with reference to one halt or the twin machine), and the construction is such'that the treadle does not become eflective thus to start the machine until after the levers 7 8 have performed their functions, as will now be explained.

i 130th sets of operating instrumentalities are driven by a single worm gear 128 (Fig. 11) mounted to turn on the shaft 34 and operated continuously by a worm 130' (Flg. 1) on a power shaft 132. The wormgear 128 serves 7 made fast. The sleeve member 134-carries a disk186 in which isswiveled a clutch pin 138 adapted to be turned either into or out of position for the reduced inner end thereof to be engaged by one or another of a plurality ot shoulders 140 formed on a ringfast in a recess in one side olithe hub of the gear 128. For controllingthe clutch pin 138 there is mounted on the periphery "of the disk 136 a ring 142 having a'recess into which loosely projects a pin 144 fast in the'clutch pin; Springs 146tendto'turn the ring 142 to a positionsuch that thepin 188 is inthe path of the shoulders 140, so that the clutch isoperative to drive the machine. When the clutch is inoperative thering 142 iseheld against the resistance of the springs 146 in a' positionsuch that, the pin 188 is out of the pathof the shoulders 140. V For this purpose vthere is provided a finger 148 arranged to engage one or the other of two shoulders 150 and 152 on the ring 142. When the finger is in engagement with the shoulder 150, the- 1 parts of the machine are in their starting positions, and when it is in engagement with theshoulder 152 they are in the. positions that they. assume with the upper under the pressure of the wipers 38 at the end'of the uppershaping operation. 1

The finger 148 is formed on a sleeve 154 which is mounted to turn on a rod 156 and is controlled bya spring 158 connected to an arm 160 on the sleeve, the spring holding the finger normally against the ring 142. To'start the machine the sleeve 154 is turned against the resistance 'ofthe spring 158 to lift-theifinger 148 and release the, ring 142; and this-is done in the first instance by the treadle 118 near the end of its movement, as already suggested. For this purpose the treadle has a rearwardly extending arm 162 on the end of which is secured a latch member 164 arranged to act upon the lowerend of a bar 166 pivoted at 168 between the two sides of arforked arm 170 projecting-from the sleeve-154. A shoulder 172'on the latch member 164, by engagement with the lower end face of the bar 166, serves to lift the bar and thus to turn the sleeve 154- andlift the clutch-controlling finger 148. Initially'the sh0ulder172-is so far below the lower end of the bar 166 that the starting of the machinedoes not occur until after the levers 78 have been moved by the treadle to their operative positions inthe manner, previously explained. The movement of the treadle is limited by engagement of a lug 174 thereon with afixed part of the machine. As

fast baa projection 1 58 the latch member 164 is lifted, aninclined r face 17 6 thereon first engagesthe bar 166 and swings the bar about its pivot 168 against the resistance of a spring 178. As the latch member continues its upward movement its upper end portion is carried beyond a shoulder 180 on the bar 166, whereupon the spring 178 a ctsto swing the bar. reversely so as to carry the shoulder 180 below a shoulder, 182 ofthe latchmember. that "it is by still further-movement of the t-readlethat the shoulder 172 acts onthe lower end face of the bar 166 tostartthe machine.

It willbe understood hen the operator releases the treadle, the I bar 166 ismoved downwardly only as far as permitted by the engagement of the clutchcontrolling finger 1481with the periphery of the ring142, and the shoulder 180 byitsens gagement with the shoulder 182 of the latch member then serves to hold the treadle against further reverse movement andt-hereby'to maintam thelevers 7 8 in engagement withthe blocks 60 ofthe presenter so as to insure that the jig pins 64 will be maintained atthe ends ofthe slots 7 6 inthe wipers until after the machine begins it's'operation upon the upper. The release. of the treadle to permit thelevers 7 8 to be returned totheir startupper.

ing positions is effected by a pin 184 (Figs. land-2) which is carried by the end of the previously mentioned lever 32 whereby downwardmovement is imparted to the form early in the cycle of the machine, the pin beingarranged to engage a cam face 186 on the upper end portion of the bar 166 so that the bar is swung by the pin to withdraw the shoulder 180,t'rom below'the shoulder 182. \Vhen the parts are in starting positions the pin 184 is in engagement with a portion of the bar-166 above the cam face 186 to limit the movement of the bar under the force of the spring 178, as illustrated in Fig. 1. After swinging the bar 166 as described to release the treadle, the pin 184 holds the bar against reverse swingingmovement until the lever 32 is lifted near the end of the cycle, whereupon the? bar is returned to its starting position by the spring-178.

The 1 machine is further provided with automatic means which acts on the presenter early in the cycle of the machine to withdraw the jig pins 64 from the holes in the This means comprises two levers 188 on-the. front ofv the machine, which are mounted for swinging movements laterally of the form and for bodily movements heightwise of the form and are provided with laterally projecting endportions 190 arranged to be carriedto positions over lateral projections 192 on the presenterblocks 15) by the lateral swinging movements of the levers, so that when the levers are moved downwardly they :act to pull the blocks 60 downwardly with them and thus to withdraw the jig pins from the holes in the upper and also from the slots in the wipers. The levers 188 are pivotally mounted at 194 on arms 196 which are pivoted on the frame of the machine for upward and downward swinging movements, these arms being normally lifted by springs 198 to positions determined by the engagement of lugs-200 on the arms with fixed. stops 202. The levers 1'88 arefurther controlled by pivoted links204 provided with slots 206 into which pins 208 on the levers ex tend for limiting the lateral swinging movements of the levers. At their lower ends the w levers 188 have-laterally projecting arms 210 which are connected by-linlrs 212 to arms 214 fast on the oppositeends of the previously mentioned rock shaft 90. Formed integral with one of the levers 214 is an arm 216 which is connected by a link 218 to a bell-crank lever 220 mounted to turnon a shaft. 222. One arm of this bell-crank lever has thereon a inember 22-1 which is arranged to be eng ed by a-roll 226 carried by the cam wheel It will thus be seen that early in the cycle, after-the blocks 600i? the'presenter-have been released by the levers 8, the roll 226 by its action on the member 224 serves toimpart downward movements to the links 212,

r as a result of which the levers 188 are first swung laterally as far as permitted hy-the slots 206'and the pins 208, thus carrying'the ends 190 of the levers over the-projections 192 of the presenter blocks 60, as illustrated in Fig. 15. the links'212 the levers 188 and their supporting arms 196 are then moved downwardly against the resistance of the springs 198=to withdraw the jig pins 64 from the upperand the wipers, as illustrated in Fig. 16. As the roll 226 continues its movement it releases the member 224, whereupon the parts'are returned to starting positions by a spring 22'. connected to one of the arms 214.

Faston the front of the machine isa bracket 228 having an upturned outer endportion arranged to serve as a support orrest in engagementwith the handle portion '58-ofthe presenter. This permits the operator to release the presenter and to proceed-with'the presentation of an upper to the other half of the machine before the pins 64 have been withdrawn from the upper, and by holding the outer end portion of the presenter against downward movement the su port also insures the proper withdrawal of'tl ie pins by the action of the levers 188. lt-will be understood'that when the operator releases the presenter as described, the jig pins 64 are supported against downward-movement out of the jig holes both by the engagement of their ball-shaped ends with' the upper supported on the wipers 38 and by their pressure against the wipers under the action of the lovers 7 8. lVhen these levers release the blocks 60 the ball-shaped 'endsof the pins are eifective toprevent-the withdrawal of the pins from'the upper until the levers 188 performthei'r'functions. When'the pins are withdrawn from the upper the extensions 62 of the block 60 fall into engagement with portions of the machine which'are spaced a short distance below the wipers to assist in supporting the presenter until-the operator removes it.

In general similarity to prior machines of the illustrated type, the machine herein shown is'also provided with "grippers for-gripping the margin of the upper at the opposite sides of the too over the outer or upper faces of the wipers 38, these grippers engaging the upper in locations substantially at the'ends of the tip seam and being movable inwardly toward theform in response tothe pull of the upper 'thereonin the upper-shaping operation while maintaining control of the margin of the upper to hold it against'undesirable shifting movement lengthwise of it's edge. The construction'of these grippers andthe means for operating them are in many respects similar to the disclosure of my prior Patent No. 1,711,946. Each gripper includes a lower jaw 230 and an upper jaw 232, the jaw 230 being fast on a bar 234 which is mounted at its upper end, as hereinafterde- By the continued movement of.

. under control of aspring2 l l which presses upwardly on a rod 246 connected at its upper end to the gripper carrier and guided at its lowerefnd by the bracket2 l0, this spring tending to swing the carrier in the direction to move the gripper jaws outwardly. For'determining the initial. positions of the grippers the machine herein'sh'own, is provided with stops 248 which are mounted'on the wipers and against which the lower aws 230 are initially held by the springs 2%. lnsur- 'ance is thus afforded that the grippers Wlll always be positioned in the right relation to the slots 76 lIlllllQ wipers when ti 2 upper is presented to-the machine, whatever may be thesize ofthe upper and the corresponding size of the wipers 38 that are used in the ma chine. Furthermore, the operator is under no necessity of adjusting the grippers for clifferent sizes, sincetheir positions are auto matically, determined by the-stops on the wipers.

ach of the blocks 242 supporting the jaw 232 is operated by a lever 250 throughJconnections hereinafter described, each lever 250 being pivotally mounted on a bracket 2521and connected at one end by Etllllli 25% i to an arm 256 fast on a rock shaft258. One

of the arms 256 is connected by a link'260 to a lever 262 provided with a roll 26% controlled by a cam formed on theperiphery of the cam.

The connectionbetween each lever 250 and the corresponding blooki242, in the construction herein shown, consists of a yieldable link which includes a rod 266 (Figs.-2 and 3) uniyersally connected to the lever 250 and a rod 268 universally connected to the block 242. Fast on the end of the rod 268 is a sleeve 270 within which is slidingly mounted a plunger 272 on the end of the rod 266, a spring 27% being interposed, between this plunger and theend of the rod 268. The rod 266 is further guided by a cap 276 which is fast on the sleeve 270. It will thus be seen that the gripper aw 232 is yieldingly held in engagement with the upper through thespring 27 1 during the movement ofthe. gripper.

In the uppershaping operation it isdesirable that the gripper jaws be maintained in as close relation as possible to the outer faces of the wipers 38, and especially that the lower jaws 230 be positioned close to the vipers at the time when theupper is presented witl between the carriers 236 and the bars 234, .the

its margin outspread over the Wipers, so that the margin of the upper may be readily presented in position to be gripped by the aws. As herein illnstratcda construction is provided such that, notwithstanding'the swinging movements of the gripper carriers 236,

the gripper aws move in paths parallel to the Y straight paths, the lower jaws moving in contact with theouter faces of the wipers which serveas guides for them. For the purpose-in-viewthe bars-234- which support the lower jaws are slidingly movable in the carriers 236 in directions transverse to the plane of the. wipers, so that the aws 230 may remainin contact with the wipers in the swing-- previously mentioned springs27 l are especially useful in maintaining the jaws 232 in gripping relation to the upper in the opera-' tion ofthe grippers on the upper.

I The previously mentioned clamp members I 50, which clamp the margin of the upper yieldingly upon the wipers around the toe in locations nearer the end of the toe than the grippers,are fast on arms 280 which are guided for upward and downward swinging movements and for bodily lengthwise movements 7 by holders 282 fast on a cover plate 284 on the headof the machine. Each of the holders 282 has in its opposite sides slots 286, into which projects a pin 288 carried by the arm 280 at its outer end, this pin-and-slot arrangement serving to guise the arm in its movements. Inthe construction hereinshownthe swinge ing movements of each arm 280are controlled by a cam member 290 secured to the holder 282 and having a face, 292 inclined to the plane of the wipers 38 and a face 294 subthe arm 280. A; spring 298 connected tothe arm 280 tends to move it outwardly and holds it initially in the position illustratedin Fig. 9 with the roll 296 near the upper end of the' inclined face 292. It will be seenthat in this 1 ment of each clamp member 50 to clamping I position is effected. through a link 300 universally connectedat one end to the arm 280 and at its other end to a lever 302 (Fig. 1) whichis pivoted on the bracket 252 and is connected to the gripper-closing lever 25.0 x

at the :same side of the machine by a link plane of the wipers, and as shown also in I (Bl! 19.6 J

stantially perpendicular to that plane, CO- I 7 operating with these two faces is a roll 296 on =304'and a spring 306, this spring being'mount- 'ed between the *lever 250 and a nut 308 (Fig. '2) on the upper end of the link 304. It will thus be seen that when the levers 250 are perated to close the grippers they also act yieldingly through the springs 306 to move the clamp members 50 to their clamping positions. In this movement the clamp members are fir'st'carried inwardly over the wipers 38 to positions opposite the portion of the'upper tobe clamped,as the rolls 296 move along the inclined faces 292, and are then moved into clamping position in a direction substantially perpendicular to the plane of the wipers as the rolls move'along the faces-294. It will thus be seen that while the clamp mem- "bers are maintained in outwardly retracted positions when the upper is presented over the Wipers, they are moved into engagement with the upper in directions such that there is'no danger of their displacing the margin of the upper when they contact with it.

Byreference to Figs. 9 and 10 it will be seen that each clamp member has a comparatively narrow clamping face 310 for applying clamping pressure to the margin of the uppernear the edge of the wiper, and has another face'312 which is spaced farther from the wiper than the face 310 when the member is in clamping position. It will be understood thatinitially'the'margin ofthe upper projects outwardly for a'co-nsiderable distance und'erthe faces 312, so that the clamping pressure isapplied by the faces 310 at a distance from the edge of the upper, and thatas the 'upper is*tcnsioned and wiped over the form the clamped margin is pulled inwardly toward the form between the wipers and the clamp members. In this operation the face 310 of each'clamp member serves as-an ironing face for smoothing out the margin of the upper. In the early stages of the upper-shaping operation, by reason of the oilset relation of the faces 312 of the clamp members, portionsof the margin of tlieup per that project outwardly beyond the ironing-faces 310 are left without any substantial pressure thereon, although the faces 312 are near enough to the wipers to prevent the margin of the upper fronrwrinkling excessively in any location. Ithas been ioundthat clamp members constructed'as described contribute materially tothe formation of a flange on the marginal portion of the upper which is smooth and regular without excessive wrinkling at any point. In shaping over a form the toe portion of an upper including box toe stiffening material it is desirable that the stiiiening'm'aterial be maintained in a. very soft and pliable condition during the uppershaping operation. This is especially true as to the marg'inal portion otthe'upper when the latter is wiped inwardly over a form to shape it for attachment to an insole,whether the margin be shaped'to conform to the feather and 'cration.

each ofthe clamp members 50 is maintained in "a heated condition by an electrical heating unit 3l4 mounted in the arm 280 over the clamp member. Electrical current is 'conducted-toeach heating unit-314 by wires 316 leading from terminal plates 318 on the side of a'box 320 which is mounted on the arm 280, these terminal plates being in engagement 'with brushes (not shown) on the side of a stationary box 322 mounted on the head of'theinachine at the side of the box 320. twill be understood that the brushes on the box 322 are connected to a source of current through acable'324. As indicated in Fig. 10, more or less of the margin of theupper remains in contact with'the clamp members 50 until the: end of the inward movement of the wipers 38, and accordingly a portion, at

least, of the stiffening material in the marginof the upper is subjected to the action of the heat throughout the upper-shaping op- After the upper has thus been shaped, it is desirable that the stiffening material shallharden as quickly as possible, es-

pecially-where, as illustrated, the hardening of this material is depended upon to holdthe upper in its molded condition without the use of fastening means until'the upper is mounted on the last. Accordingly the clamp members 50 are liftedand retracted-away from the margin of the upper and the wipers immediately-after the wipers have arrived in the position indicated inFig.10, thus leaving the margin of the upper to set under pressure Without the application of heat thereto, as illustrated in Fig. 8.

The toe band 36and associated parts are in many respects similar to the construction disclosed in Letters Patent No. 1,692,284. The band 36, which maybe made of leather,

is secured to supporting members or holders 326 mounted on carriers 327 which rest upon a portion of the frame of the machine and are swiveled on the head 328 (Fig. 6) ofa rod 330 for swinging movements toward and from each other about a vertical axis. The rod'330 in the construction herein shown is slidingly mounted in the head 332 of a bolt 334 which is swiveled in a lever 336 controlled 1 as hereinafter described. Between the head 328 and the head 332 is a compression spring 337. Mounted in a recess in each of the carriers 327 is a spring 338 which bears at one end on a screw'340 threaded in the recess in the carrier and at its other end on a collar 342'which is threaded on a rod 344 extending through the carrier and slidingly mounted in an opening in the screw 340, the collar being provided with a pin 346pr0- j ecting into a slot in the'carrier to prevent it from turning. A. pin 347 in each carrier 327 is arranged to engage the collar 342 on one end to limit relative movement of the collar and the carrier in one direction. Each rod 344 has a ball-shaped end 348 mounted in a slot 350 in the end of a plunger 352 which is slidingly mounted in the head of the machine. /Vith thelever 336 and the plungers 352 maintained in a stationary condition, the upwiping device, comprising the band 36 and the members 326 and'327, may move bodily lengthwise of the upper and the form against the resistance or" the central spring 337 and of the two side springs 338 in response to the pressure of the upper and form on the band. 36 as the form is moved downwardly, and the opposite side portions of the upwiping device also may be swung apart Y in response to the pressure thereon against the resistance of the springs 338. I In addition, the members 326 and 327 with the band 36 may move bodily widthwise of the form toequalize the pressure on the opposite side portions of the upper, by reason of the mannerin which the rod 330 is mounted and connected to the carriers 327 and the provision for sliding movement of the ends 348 of the rods 344 in the slots 350. The positions of the carriers 327 relatively to each other may be adjusted by turning the threaded rods 344,

whereby the collars 342 are moved length-.

wise of the rods, each rod having in its front end a slot for the purpose of turningit. I

The means for controlling, the lever 336 and the plunge rs 352 are substantially as described in Letters Patent No; 1,692,284. The

plungers are connected to arms 354 which are fast on a rock shaft 356having an arm 358 (Fig. 1) connected by a link 360.to;a lever 362 operated by a. path cam formed in one side of the canrwheel 48,. The lever 336 which controlsthe intermediate portion of thetoe band is pivoted .at one end at 364 to a sliding member 366 guided by a-pin-and-slot connection 368 to the head of the machine, one end or the member 366 being connected (Fig. 6) to The other end of the 7 lever 336 is connected to anadjusting rod 370 which extends through an opening in the frame and has threaded on its end an adjusting nut 372, a spring 374 beinginterposed between the frame and a collar 376 fast on the rod. By means of the nut 372 the intermediate portion of the toe band may be j that uponreverse movement of the arms the plungers and the rod are retracted, whereby the upwiping device is moved bodily length- It will band tothe upper while the upper is setting under the pressure of the wipers as shown in,

Fig. 8. In the return of the parts of the machinelater to starting positions the plungers 352 and the rod 330 are again advanced to position the toe band ready for operation on another upper.

After-the machine. has been started by depression of the treadle 118 in the manner hereinbefore described, it runs until the shoulder 1520f the clutch ring 142 arrives in position to engage the end of the finger 148, whereuponthemachine comes automatically to a stop-at a point in the cyclewhen the upper is held under pressure by the wipers 38, as illus trated in Fig. 8. The machine herein shown is provided with automatic means for again starting'it after the upper has remained under pressure of the wipers for a V definite length of time. For this purpose there is associated with each half of the machine autem'atic mechanism forilifting'the finger 148 out of engagement with the shoulder 152. This mechanism, in either half of the ma.- chine.-comprises a ratchetwheely378 (Figs. 11 and 12) mounted to turn on the rod 156 and held normally by a torsion spring 380 in a position determined byengagement of a lug 382 on the ratchet wheel with a stop 384 which may be fastened by a screw 386 in any one of a number of adjusted positions on a holder 388 which is a part of a casing'390 mounted over the gearwheel-128. The ratchet I the sleeve to lift the clutch-controlling finger 148. Movement is imparted to the ratchet wheel378 by a pawl 396 mounted on the lower end of an arm 398which is mounted to swing on the rod 222. this arm having mount- .ed thereon a roll 400 in the path of two cams 402 which are carried by the hub of the gear wheel 128i A sprine'403 acts onthe arm 398 to hold the roll in'the path of he cams. It will thus be seen that the'arm398 is operated intermittently at all times by the cams 402, but norspring 380 to the position determined by the stop 384 each time that the pawl 396 is retracted. To render the ratchetwheelopera- -mally the ratchet wheel 378 is returned by the tive for the purpose described, there is provided a holding pawl 404 which is pivotally mounted at 406 on the base of the machine and has rigidly connected therewith an arm 408 on which is mounted a roll 410 arranged to engage the periphery of the cam wheel 33. A spring 412 tends to pull the pawl 404 into position to engage the ratchet teeth, but normally the pawl is held out of engagement with the teeth by the periphery of the cam wheel 33. Immediately before the machine is stopped by engagement of the linger 148 with the shoulder 152 a depression 414 in the periphery of the cam wheel arrives in a position opposite the roll 410, so that the spring 412 is permitted to swing the pawl 404 into engagement with the ratchet teeth. lVhen this occurs each succeeding movement of the arm 398 by the action of either cam 402 thereon serves to advocate the ratchet wheel the space of one tooth,the wheel being held from reverse movement by the pawl 404. Accordingly, after a definite number of such movements of the ratchet Wheel have been effected, determined by the starting position of the wheel as adjusted by the step 384, the screw 392 arrives in position to lift the finger 148 and thus actuates the clutch to start the machine again. Immediately after such starting of the machine the pawl 404 is withdrawn from the ratchet teeth by the cam wheel 33, whereupon the ratchet wheel 37 8 is returned to its starting position by the spring 380. By the provision of this auto matic starting means not only is the operator relieved of the necessity of starting tl e machine the second time, but the length of time during which the upper remains under the pressure of the wipers is automatically determined, so that the different uppers are treated uniformly.

In the machine herein shown the wipers 38 are secured in position on the wiper holders 39 by means which permits them to be readily detached when it is desired to substitute a different set of wipers. By reference to Figs. 9 and 10 it. will be seen that the wipers are mounted in undercut grooves in thewiper holders, and they are held in these grooves by retaining members 416 (Fig. 5), one on each wiper holder, these members being arranged to engage the front end faces of the wipers to hold them in position. Each memher 416 is slidingly movable in a slot in the wiper holder against the resistance of a spring 418 and has thereon a projection 420 by which the operator may withdraw it from engagement with the wiper. the projection 420 lying in a slot 422 in the wiper holder whereby the movement of the member 416 is limited.

In the operation of the machine, briefly summarized, the operator mounts an upper on the presenter with the jig pins 64 project ing upwardly into the jig holes in the upper,

as illustrated in Fig. 13, and then moves the presenter into position for the jig pins to enter the slots 76 in the wipers included in the upper-shaping instrulnentalities of one half of the twin machine, the margin of the upper around the toe thus being positioned outspread over the outer faces of the wipers and over the lower gripper jaws 230 which are positioned adjacent to the slots 76 by engagement with the pins 248. It will be understood that before such presentation of the upper the box toe stillening material will have been softened by heat by the use of any suitable means for that purpose.

Having presented the upper as above described, the operator depresses the starting, treadle 118 and thereby moves the levers 78 upwardly and rearwardly into engagement with the blocks of the presenter, as illustrated in Fig. 14, thus insuring that the jig pins 64 will be moved fully to the inner ends of the slots 76 in the wipers. By continued movement of the treadlc the clutch-controlling finger 148 is lifted to start the machine by the action of the shoulder 172 of the member 164 on the lower end of the bar 166. The operator may then release the handle 58 of the presenter and give attention to the preparation of an upper for presentation to the other half of themachine, the presenter being supported by engagement of the member 228 with its handle portion and by engagement of the ball-shaped ends of the jig pins with the upper supported on the wipers 38. The shoulder 180 on the bar 166, by engagement with the shoulder 182 of the latch member 164, serves to hold the treadle against return movement to starting position, so that the levers 78 are maintained in holding rela tion to the blocks 60. Shortly after the starting of the machine the pin 184 acts on the bar 166 to release the treadle, whereupon the lovers 7 8 are returned to their starting positions. As the machine begins its operations on the upper, the levers 188 are moved in the manner described to engage the projections 192 on the blocks 60 and withdraw the jig pins 64 from the holes in the upper and from the slots in the wipers.

In the operations on the upper the heated clamp members 50 are moved inwardly and then downwardly into positions to clamp the upper yieldingly on the outer faces of the wipers. and the gripper jaws 232 are moved into gripping engagement with the margin of the upper at the ends of the tip seam. As the form 20 is carried downwardly by its arm 22 it presses portions of the upper against the toe rest 52 and forces the latter downwardly with it, the form being depressed within the toe band 36 which acts to wipe the upper height-wise of the form. The upper is thus tensioned and wiped over the form, portions of its margin being withdrawn from between the wipers and the heated clamp Patent of the United Statesisz:

V In: the wipingoperation themargin of the upper 1s turtherpu-lled inwardly between the clamp members and the wipers, and the grippers also are moved .tarther inwardly, the latter finally releasing their'hold on the upper. It 'will be evident that the stiffening material the margin ot'the upper aroundthe toe is thus'maintained in a heated condition" by the clamp members during the tensioning-otthe upper over the torm and during the wiping of'its margin inwardly bythewipers.
