47 Claims.

This invention relates to upper-shaping machines and is herein illustrated in its application to machines for shaping uppers'without the aid of a last.

The term upperj as hereinafter employed, is in most cases used generically and includes the counter stiffener and is to be so construed unless the context requires that the term be specificallyconstrued. I

In themanufacture of some types of shoes it is advantageous to shape the upper without the aid of a last in order that the interior of the upper may be accessible for the performance of operations subsequent to the upper-shaping operation. An example of shoe constructions which require theshaping of the upper without the aid of a last is disclosed in United States Letters Patent No. 2,212,514, granted August 27, 1940, on'an application filed in my name.

In the manufacture of shoes in accordance with methods which require the shaping or molding of the back part or quarter before it is attached to the forepart or vamp it is a usual practice to shape such backparts without the aid of a last, the last ordinarily being inserted into the upper after the molded back part has been attached to the vamp. V

It is an object of the present invention to provide an improved upper-shaping machine adapted to shape uppers, or the back parts or quarters of uppers, which have not been assembled on lasts. It is a further object of the invention to provide in such a machine suitable means for forming a well-defined inwardly extending flange in the rear part of the upper to facilitate the attachment of the rear part of the upper to a sole in accordance with the method set forth in my patent above referred to, or in any other suitable manner.

In manufacturing shoes in accordance with methods which require a closed upper to be initially shaped without the aid of a last, it is desirable to provide means for shaping the instep portion of the upper in order to provide in that portion of the upper sufiicient space for the foot of the wearer. This is particularly desirable when, as in the method set forth in my patent above referred to, the last is not inserted into the upper until the manufacture of the shoe is nearly completed, and, consequently,- the shoe is on the last but a short time. Accordingly, it is an obthe instep portion of the upper;

In the manufacture of high-grade shoes,

manufacturers often prefer to provide their uppers with heel stiifeners or counters which have not been molded, or have been only partially molded, prior to their insertion into the upper.

The final shaping of such counters is effected in shaping the rear part of the upper. This shaping in most cases requires the formation in the counter of an inwardlyextending flange. Counter materials commonly used for counters of this type are of a fibrous nature and the flange formed in the counter in the upper-shaping operation tends to spring back to its original position after the flange forming pressure is released. With this in view, it is an object of the present invention to provide flange forming means adapted to bend the flange beyond the desired angular position of the flange relatively to the body offthe counter to an extent equal to the normal reactive movement of the flange.

With the above and other objects in view, as will hereinafter appear, the present invention consists in the provision in an upper-shaping machine of means for shaping an end portion of an upper, means for holding the upper under lengthwise tension during the shaping operation and means for applying pressure to the instep portion of the upper in a direction generally heightwise of the upper to shape said instep portion while the upper is held by said shaping means and said tensioning means. The upper shaping means, as herein illustrated, comprises a pair of rear part shaping molds which are mounted in mold carriers and have yielding connections to the carriers which permit movement of the molds relatively to the carriers for a purpose now to be described. In order to obviate any pinching or abrading of the rear or backseam portion of the upper by closing action of the molds, the shaping of the rear part of the upper is effected by relative movement of the molds and the inner heel form lengthwise of the upper combined with the closing action of the molds, and said closing action is completed before such lengthwise movement has brought the back-seam portion of the upper into contact with the end portions of the molds. The latter part of such lengthwise movement wedges the molds away from each other so that their rear end portions are separated slightly when the upper comes in contact with them, and consequently there is no possibility of damage to the back-seam portion of the upper by pinching it between the adjacent end portions of the molds.

For holding a closed upper under lengthwise tension during the heel-shaping operation the illustrated machine, in accordance with a further feature of the invention, is provided with means for gripping the toe end of an upper mounted on the inner heel form, means for gripping opposite side portions of the forepart of the upper, said toe gripping means and side gripping means being yieldingly connected to a fixed portion of the machine in order that lengthwise tension may be imparted to the upper as the inner heel form advances to force the rear part of the upper into the rear part shaping molds. In accordance with a further feature of the invention the side grippers are carried by a slide mounted on the member which carries the inner heel form and movable on said member in a path inclining downwardly and heelwardly relatively to the upper. As the inner heel form advances into the rear part shaping molds, the slide is held back by its yielding connection to said fixture and there is a differential movement of the heel form carrying member relatively to the slide which causes the slide to move heightwise of the upper, tensioning the forepart of the upper about the instep-shaping means. The lengthwise and heightwise tension imparted to the upper is maintained during theremaining operations of the machine and serves to hold the upper on the heel form in proper position for the operation of the rear part shaping means and to hold the forepart' of the upper during the operation of the instep-shaping means.

In accordance with a further feature of the invention, the instep portion of the upper is shaped by a member constructed and arranged to operate against the inner surface of the instep portion only while the forepart of the upper is held by the gripping means. The illustrated instep-shaping member is carried by the inner heel form and arranged for movement generally heightwise of the upper.

For forming an inwardly extending flange in the rear part of an upper, or in a back part, or quarter, which has not been attached to a vamp, the illustrated machine, in accordance with a further feature 'of the invention, is provided with a wiper for wiping the lasting margin of an upper on the inner heel form inwardly over the heel seat face of the form while the upper is held under lengthwise tension, and for assisting in the flanging of the overwiped margin, a flange former is arranged for operative movement heightwise of the upper to press the overwiped margin against the heel form after the wiper has completed its overwiping movement. In order that the flange former may bend the margin of the upper beyond its desired angular position so that the reactive movement of the counter with which the upper is provided will leave the margin of the upper in the desired angular position, the heel seat face of the inner heel form, in accordance with a further feature of the invention, is recessed and the flange former is constructed and arranged to press the margin of the upper into the recess in the form, the flange former and heel form acting as dies to shape the margin of the upper. The illustrated flange former moves in a direction perpendicular to the path of operative movement of the wiper through a suitable opening provided in the wiper. In order to obviate possible dislocation of the overwiped margin of the upper by the retraction of the wiper, means is provided for automatically lifting the wiper away from the upper during the interval between the operation of the wiper and its retraction.

For positioning the rear part of the upper heightwise thereof on the inner heel form, the illustrated machine is provided with novel gaging means herein illustrated as a pair of gage members constructed and arranged to engage the edge of the lasting margin, and connections are provided from the wiper to the gage members for moving the gage members out of the path of movement of the wiper as the wiper is advanced.

These and other features of the invention will now be described with reference to the accompanying drawings and pointed out in the appended claims.

stretching member.

Referring to Fig. 1, the illustrated machine comprises a frame 30 having a flat top 32 which inclines downwardly and forwardly toward the work supports of the machine. Mounted in the upper portion of the machine for rectilinear movement in a direction parallel to the flat top 32 is a slide I58 which carries molds for shaping the rear part of. 'a shoe mounted on the work supports. .Fulcr'umed at 204.cn brackets extending rearwardly from the upper portion of the frame is a head comprising two plates 202 spaced apart from each other widthwise ofthe machine and securedto. a rigid channel membe'r36 which forms 'an arch over the forward portions of the plates 202. Mounted between the platesfl202is a slide 200 which carries a wiper member 56. The operatingmechanisms are covered by a hood 34 secured to the member 36 and extendingrearwardlyfrom said member and downwardly to'the back of the machine frame, said hood being sufliciently flexible to permit a slight upward swinging movement of the machine head. During the advancement of the wiper 56, the head'is so positioned that the wiper travels in a path parallel to the path of movement of th slide I58 which} carries the rear part shaping molds. 'Beforethe wiper is retracted, the head is swung upwardly slightly to bring th wiper out of contactwith the work thus obviating. any possible dislocation of the work by the retraction of the wiper. :For mounting the work-supporting mechanism a bracket 38 is secured to the front of the. frame .and has a top surface 40 inclined; forwardly and downwardly in a plane parallel ,to. the plane of thetopsurface 32 of the frame 30. Th top of the bracket 38 provides a mounting for a. slide 12 which carriesan iner. heel form 42 against which operatethe rear part shaping molds 44. During the operation of themachine the upper isheld in a predetermined. position on the form 42 by toe grippers and side grippers hereinafter. described-" For actuating the operating parts of the machine a motor 46 is mounted on the base of the frame and arranged to drive a pulley 48 which operates a pulley .50 loosely mounted on: a cam shaft 52. For operatively connecting the pulley 50 .to the cam shaft, the machine is provided with a one-revolution clutch mechanism (not shown) which is operated by the depressionof.

a'treadle' 54.x .Upon depression of said treadle the-cam shaft makes one complete revolution in a clockwise direction as seen in Fig. 1, turning cams mounted on said shaftythe cams being suitably contoured to actuate the operating parts of the machine in predetermined time relation through linkagesillustrated generally in Fig. 1

and hereinafter'more fullydescribed.

In-the course of the machine cycle the inner heel form 42 movesupwardly and rearwardly, while the rear part embracing molds 44 .move,

downwardly and forwardly and close upon the rear part of an upper on the form. The upper,

may be provided with any suitable counter stiffener but the illustrated machine is particularly adapted to operate on an upper provided with a counterwhich hasnot been molded or has been only partially molded. The uppershaping mechanism .of the-illustrated machine is well-adapted to-complete the shaping of such a counter and form an inwardly extending flange;

therein. ,After the molds 44 have closed on the upper;the rear part wipingmember 56 advances and-wipes the lasting margin projecting above the inner heel :form 42 over the edge of the form. the wiper advances, it carries with ita flange forming or molding member 58 and when the wiper comes to the limit of its operating movement, the, flange former is arranged for downwardgmovement through an opening provided inthe wiper member "to form or mold the overwiped lasting margin of the upper against the top surface of the form 42. It will be understood that the principal function of the flange former is to shapeor flange the bottom margin of a non-,-

molded counter with which the upper has been side grippers and their operating mechanism, the.

fixed jaws 62 of said grippers are formed in a slide. 64 having inwardly extending T-shaped tongues 66, mounted in suitable grooves provided. in a rearward extension 68 (Fig. 3) of an L- shaped member 10 secured to a slide 12 mounted in the bracket 38. Referring again to Fig. 2, two movable gripper jaws 14 are formed in the lower portions of two Vertical levers l6 and are arranged to act against the flxed jaws 62. The levers 76 are pivoted to lugs I0 extending outwardly from the slide 64. These levers I6 as seen in side elevation (Fig. 7) aregenerally U- shaped and their dimension lengthwise of the. upper is such that they engage a substantial ex.

tent of the lasting margin. For simultaneously operating the movable gripper jaws 14, a hand lever 80 (Figs. 2 and 7) is mounted on a cross pin 82 carried by upward extensions 84 of the,

slide 64 and pivoted at its rear end to a member 86 swivelled on a pin 88 connecting the inner ends of toggle links 90 the outer ends of which are pivoted respectively to the levers I6 (Fig. 16).

During the rearward and upward movement ofthe inner heel form 42, the toe end of the upper is .held by grippers, now to be described, which operate to tension the upper during said move- I groove. connections 91 to a standard 98 secured to the bracket 38, said connections affording sliding movement of the plate 96 in a direction parallel to the plane of the top surface 40 of the bracket 38. Co-operating with the fixed gripper jaw 92 is a movable gripper jaw I 00 (Fig. 2) fromed in a central downwardly offset portion I02 of a plate I04 arranged for vertical movement relatively to the plate 96, such movement being controlled by headed screws I06 extending through holes in the plate 96 and into the end portions of the plate I04.

For operating the gripper jaw I00, an eccentric I08 provided with a hand lever I I 0 is mounted on a cross pin II 2 between abutments provided by the inner ends of bearings I I4 extending inwardly from downward extensions I Referring to Fig. 20 the toe grippers and the side grippers are yieldingly held at the limit of theirforward movement by springs H8 and I20 respectively, there being two such springs for each gripper assembly. The springs [I8 encircle rods I22 extending forwardly from the end portions of the plate I04 and are confined between nuts I24 on said rods and brackets I26 extending out wardly from the standard 98, said brackets being provided with holes through slide. The springs I20 encircle rods E28 extending rearwardly from bosses I30 in the upper portion of the standard 98. The rods I28 extend through holes in cars I32 1 slide. 64 and. the springs I20 are confined between I6 of the plate 96.

which the rods I22 extending outwardly from the said ears and nuts I34 on said rods. The springs H8 and I20 yieldingly hold the toe gripper and the side grippers at the limit of their movement toward the standard 98. It will be understood that the springs act to tension the upper lengthwise thereof during the movement of the inner heel form 42 away from the standard 98 in the course of the operation of the machine. This movement of the inner heel form is effected by moving the L-shaped member in which the in.- ner heel form is mounted, said member having a deep groove I36 (Figs. 2 and 3) in which the shank portion I38 of the heel form is secured by a screw I40. In order that theside grippers may tension the upper heightwise during the movement of the inner heel form away from the standard 98, the grooves 61 (Fig. 3) in which the slide 641s mounted, are arranged atan inclination such that the slide 64 and the side grippers carried thereby have a movement heightwise of the upper during theactuation of the L-shaped member 10 which movement causes the side grippers to tension the upper heightwise against the instepshaping member preparatory to the operation of said member.

For positioning the rear part of an upper, for example, the upper I42 illustrated in Figs. 6, '1, and 8, heightwise on the inner heel form 42, the illustrated machine is provided with two gage members I44 constructed and arranged to act against the edge of the lasting margin of the rear part of the upper. Each gage member acts on one side of the rear part of the upper and extends along the curve of the rear part of the upper almost to the back seam (Fig. 6). The

upturned ends I50 (Fig. '1) of the gage members are secured to upturned ends I48 of bell crank levers I46 and are adjustable vertically thereon. The rear portions of the bell crank levers I46 have slots I52 (Fig. 6) which receive pins I54 extending upwardly from the ends of diverging arms of a member I56 secured to a slide I58 which actuates the rear part embracing molds 44. During the closing of the molds on the upper, the slide I58 moves toward the rear part of the upper and it will be seen that this movement of the slide swings the bell crank levers I46 in a direction to move the gage members I44 into a position remote from the upper as shown in Fig. 9, thus providing clearance for the advancement of the wiper assembly,

The rear part embracing molds 44 are metal blocks each of which has the contour of onehalf of the rear part of a shoe formed in its innor surface I60 (Fig. 10). The molds 44 are mounted on carriers I62 having inwardly extending flanges I64 to which the mold members are connected by headed screws I66 extending through short slots I68 provided in lugs I10 ex-. tending outwardly from the mold members and affording relative movement of the mold members and their carriers widthwise of the shoe. The mold members are yieldingly urged toward each other by springs I12 (Fig. 6) interposed between the mold members and their carriers. The carriers I62 are fulcrumed at I14 on arms I16 ex? tending inwardly and forwardly from opposite sides of the upper portion of the frame 30. Re.- ferl'ing to Figs. 1 and 9, the rear part embracing molds 44 are operated by movement of the slide I58 toward the rear part of the upper. This slide is mounted for rectilinear movement in a guideway in the upper portion of the machine frame and has fulcrumed at opposite sides of its forward extremity two arms I18 (Fig. 9) the outer ends of which are fulcrumed to the rear portions of the carriers I62. As the slide advances from its position in Fig. 6, to its position in Fig. 11, the arms I18 exert a toggle action on the carriers I62 closing the rear part embracing molds on the upper.

For simultaneously operating the inner heel form 42 and the rear part embracing molds 44 a cam I on the cam shaft 52 is arranged to act against a roll I82 at the lower end of a bent lever I84 fulcrumed on a shaft I86 and pivoted at its upper end to a link I88 connected at its forward end to the slide I58. The bent lever I84 is connected by a link I90 to a lever I92 fulcrumed at I94 and pivoted at its upper end to a link I96 which in turn is pivoted at its forward end between lugs I91 (Fig. 5) on the base plate 12. It will be understood that as the cam I80 turns in a clockwise direction, as seen in Fig, l, the bent lever I84 swings in a counter-clockwise direction moving the inner heel form 42 with the upper thereon toward the rear part embracing molds 44 and simultaneously closing the molds on the rear part of the upper. The actuation of these parts is so timed that the molds 44 have nearly completed their closing movement while the form 42 is still about one-half an inch from the limit of its rearward movement. See Fig. 9. As the cam I80 completes its operation, the inner heel form moves rearwardly from its position in Fig. 9 to its position in Fig. 11 and the carriers I62 continue their movement toward each other compressing the springs I12 and increasing the pressure of the molds against the upper. During this final movement of the inner heel form, it exerts a wedging action on the molds causing them to move away from each other slightly against the yielding resistance of the springs I12, into their position shown in Fig. 11, wiping the upper about the form 42, and obviating any pinching or creasing of the upper which might occur if the molds were to close on the upper without such separation of their rear portions during the latter part of their closing movement.

The form 42 and the molds 44 complete their operation at an early stage in the machine cycle and during the remaining operations of the machine, the upper is firmly held between the form and the molds by the cam I80 which, as seen in Fig. 1, has a long dwell extending around more than one-half the periphery of the cam.

After the form 42 and the molds 44 have completed their operation and gripped the rear part of the upper between them, the rear-part wiper member 56 is actuated to bend the lasting margin of the upper over the edge of the form 42 and wipe it inwardly over the heel seat face of the form. Referring to Figs. l3, l4, and 16, the wiper member 56 is a generally rectangular plate having a V-shaped notch I98 in its forward portion the edges of which engage the lasting margin of the upper to perform the wiping operation. The wiper is carried by a slide 200 (Figs. 13 and 14) mounted in longitudinal grooves in the plates 202. Referring to Fig. 16, the wiper is secured to the slide 200 by screws 2I0 two of which extend upwardly through open-ended slots 2I2 in the rear part of the wiper while the forward screws 2I0 (Fig. 13) extend downwardly through holes in the slide 200 and are threaded into tapped holes in the wiper. It will be seen that only the forward screws need be disengaged from the wiper to permit the wiper to be removed from the machine, Referring to Fig. 16,

the wiper is automatically operated by a 'cam' 2I4 on the shaft 52 which cam acts against a roll 2 l6 on a bent lever 218 pivoted onthe shaft I86; the upper portion of said lever being bent forwardly and connected by a link 220 to lugs 222 on the slide 200.

Referring now to the construction and operation of the flange former 58 (Fig. 19), theillus-' trated flange former is a metal block or die 113V",

ing a peripheral contour similar to the heel seat portion of a shoeand having downwardly converging bottom faces 224 which engage the overwiped margins of the upper materials and press them downwardly into a concave recess 225' in the inner heel form 42, which, it will be understood, acts as a female die in the flange-forming operation. The flange former over-molds the over-wiped margins of the upper materials to a predetermined extent such that the normal spring-back of the margin of'the counter in the upper will leave the overwiped margins in the proper position for attachment to an insole, or substantially in a commonplane. The flange former is removably secured by screws 228 to the bottom face of a slide 230. Referring to Figs. 13 and 14, the illustrated slide is'mounted ina guideway in an upward extension 232 of the slide 298 for movement in a path at right angles-to the pathof movement of the slide 290, the movement of the slide 230 being directed and controlled by tongue and groove connections 233 (Fig. 1%) between the slideand the extension-232. The flange former assembly moves forwardly with the wiper assembly during the wiping operation, this movement of the wiper assembly trans ferring the flange former from its position remote from the upper [42, illustrated in Fig'. 13; to a position directly over the rear part of theupper. In its operation the flange former moves heightwise of the upper through an opening 234 (Fig. 16) provided in the wiper member 56 and into the concaverecess in the form 42 (Figs. and 19). For operating the flange former, a cam 235 (Fig. 15 on the cam shaft 52 is constructed and arranged to act against a roll 238 on 'anarm 24G fast on the shaft I86. An arm 24I fast on the remote end of said shaft, as seen in Fig. 15, hasswiveled to its upper end a block 242 (Figs. 14 and 15) slidably mounted on a rod 244 piv-' oted to an arm 246 secured to one end of a shaft 241, said shaft being journaled in upward extensions 248 on one of the plates 292. An arm 254 secured to the forward end of the shaft 241 has swiveled at itsforward end a block 256 constructed and arranged to slide in a longitudinal slot258 provided in a lever 260fulcrumed at 262 on the upward extension 232 of the wiper slide 2%. The lever 260 islconnected by links 264. to the slide 230 which carries the flange former 58'. During the operation of the wiper member 56, the slot 258 in thelever 260 is parallel to the wiper slide 260 and the lever 26%] moves longitudinally relatively to the block 256 without moving the flange former In the operation of the machine, the block 242 on the arm 24! is moved forwardly or to the left, as seenin Fig. 15, acting against a spring 2550 surrounding the rod 244 and confined between the block 242 and nuts 252 on the rod. During the latter part of the movement of the arm 24! after the flange former has entered the concave recess in the form 42, the arm compresses the spring 258 thus increasing the pressure of the flange former against. the overw ped margins of the upper materials.

Referring now to the constructionandIopera tion of the instep-stretching and-shaping mem-' ber (Figs. 3 and 4) said member comprises a form 268 removably secured to a lever 21. by a headed screw 212. The form 268, as shown in Fig. 4, has a convex bottom surface which in the operation of the member acts against the inner surface of the instep portion of the upper. The lever 210 is pivoted to a slide 214 mounted in a T-way provided in the bottom of the. extension 68 of the L-shaped member 10. The instep shaping' member is yieldingly held at the limit of its upward movement by a leaf spring 218 secured to the lever 210, the front end of said spring being upturned for engagement with the bottom surface of the extension 58. For operating the instep-shaping member, aslide 218 (Fig. 15) is splined in a bore provided in a bracket 280 extending inwardly and upwardly from the front of the frame 30. "The slide 218 has at its upper end a forwardly extendingarm 282 which carries a roll 284 which engages the top of the lever 218 when the inner heel form 42 is at the limit of its rearward movement. For moving the slide 214 downwardly to operate the instep-shaping member a cam 286 (Fig;'22) .on the cam shaft 52 is'construc'ted andarranged to act against a roll 288 on a lever 293 which swings on a fixed fulcrum 292 and is connected by a link 294 to the lower end of the slide 218. When the machine is'at rest, as seen in Fig. 1, the rear end of the lever 21!] is spaced away from the roll 284 sufiiciently to permit an upper to be moved up wardly between the lever and the roll preparatory" to assembling the upper on the inner heel form 42."

In the operation of the machine, as herein i1- lustrated, a closed upper; for example, the upper I42 illustrated in Fig. '7, is moved upwardly byfthe operative from a position beneath the inner heel form 42 into the" position illustrated" in Fig. 7; this position being determined by the engagement of the edge of thelasting margin ofthe upper with the gage members I44. The back seampf the upper, where the upper has a back seam, is centered between the inner ends of the ga e members (Fig. 67. Where the upper hasno back scam the lasting margin. ispreferably notched to indicate the point which should be centered between the inner ends of the gage members. After the rear part of the upper has been positioned on the form 42 the toe-end of the upper is placed between the toe gripper jaws 82 and lull (Fig.7) and the jaws are closed by the operation of the hand lever III]. The lasting margin of the upper, or, if desired, the last ing margin of the liningonly, at opposite sides of the ball portion is then positioned between the jaws of the side grippers whereupon the side grippersare closed simultaneously by the operation of the hand lever 80. In positioning the lasting margin in the side grippers, the operative wraps the upper about the instep-stretching and-shapingmember to arrange it for the instep-sha in operation. The operative now depresses the treadle 54 to start the machine. Immediately upon depression of'the treadle, the inner heel form' 42 moves toward the rear-part shaping molds 44 and the molds close while the gage members I44 swing outwardly from their position illustrated in Fig. 6 to their positionillus trated in Fig. '9 in order to provide clearance for the advancement of the wiper-carrying slide 200. During the advancement of the form 42, the side grippers move upwardly to stretch the upper heightwise about the instep-shaping member.

The side grippers and th toe gripper are yieldingly held against rearward movement with the inner heel form 42 by the springs H8 and I20 (Fig. 20) and these springs act during the advancement of the form 42 to tension the upper lengthwise. Thus, it will be seen that the upper is drawn tightly about the end of the form 42 as the form advances and is also drawn tightly about the instep-shaping member. Thus, when the form 42 comes to the limit of its advancement, the grippers will have positioned the upper for the various operations of the machine thereon and the upper will be securely held by the grippers until the machine has completed its operations. During the advancement of the form 42, the molds 44 are closed on the rear part of the upper by the operation of the slide I58 (Figs. 6, 9, and 11) acting through the arms I18 to swing the mold carriers from their position illustrated in Fig. 6 into their position illustrated in Fig. 11. The closing of the molds 44 on the rear part of the upper is completed just before the inner heel form 42 comes to the limit of its advancement and as the form 42 completes its advancement, it exerts a Wedging action on the molds 44 against the yielding resistance of the springs I12 (Fig. 6) spreading them slightly into the position illustrated in Fig. 11 and obviating any pinching or creasing of the back-seam portion of the upper by the molds. After the rear part of the upper has been thus gripped against the form 42 by the molds 44, the wiper member 56 advances from its rest position, illustrated in Figs. 1 and 16, into its position illustrated in Fig. 18 wiping the lasting margin of the rear part of the upper inwardly over the heel-seat portion of the form 42. After the wiper member has completed its wiping operation, it continues to advance into its position illustrated in Fig. '18 in order to position the flange former B in alinement with the concave recess 226 (Fig. 19) in theform 42. The flange forming member 'is now moved downwardly through the opening 234 provided in the wiper member 56 and pressed hard against the overwiped margins of the upper materials, overmolding them to a predetermined extent such thattheirnormal spring-back will position them for attachment to an insole. During the operationof the flange molding member the instepstretching and-shaping member is operated by the cam 286 (Fig. 22) which moves the slide 218 downwardly, said slide acting on the lever 210 of the instep-shaping member. It will be understood that the lever 210 is positioned beneath the roll 2B4 carried by the slide 218 in the course of'the advancement of the inner heel form 42. After the instep-shaping member has completed its operation, the entire machine head including the wiper assembly and the flange-former assembly are swung upwardly to separate the wiper and the flange-former fromthe molded margin of the rear part of the upper, thus permitting the wiper to be retracted without danger of dislocat ing or disfiguring the molded margin of the upper. For swinging the head upwardly, the illustrated machine is provided with two duplicate cam mechanisms arranged at opposite sides of the machine and connected respectively to the forward portions of the plates 202 which formthe base of the swinging head. Referring to Fig. 1, which illustrates the cam mechanism connected to the plate 202 at the left of the machine, a cam 298 on the shaft 52 is provided'with' a groove 300 in which is mounted a roll 302 carried at the lower end of a rod 304 slidably mounted in a bearing in a bracket 306 extending inwardly from the inner surface of the frame 30, the rod 304 being pivotally connected to the plate 202 at the left of the machine. After the head is swung upwardly by the operation of the duplicate cam mechanisms, the flange molding member is moved upwardly into its rest position and the wiper member 56 is retracted and, at the same time, the

slide 218 (Fig. 22) moves upwardly permitting the return of the instep shaping member to its rest position by the spring 216 (Fig. 3). Thereupon, the rear part shaping molds 44 open and the inner heel form 42, together with the upper gripping assemblies, moves forwardly into its rest position. The operative then disengages the gripper members from the upper and removes the upper from the machine.

While the operation of the illustrated machine has been described with reference to the shaping of a closed upper, it will be understood that the utility of the machine is not limited to the shaping of closed uppers since it is well adapted to operate on quarters or back parts which have not been stitched to their Vamps. In operating on such back parts the operative will manually tension the back part about the inner heel form as the form advances into the molds, the toe grippers and side grippers remaining idle. After the molds close on the back part and grip it against the form, they control the position of the back part and no further attention thereto by the operative is required. The operation of the molds, the wiper, and the flange former will proceed as hereinbefore described, operating on the back part in exactly the same manner as they operate on a closed upper. Th molded back part thus provided requires no further shaping but is ready for attachment to a sole.
