, In Germany September 20, 1932 73 Claims.

This invention relates to machines for ironing the bottoms of shoes, and more particularly, in various important aspects, to means for ironing the marginal portion of upper materials (hereinafter referred to inclusively as the upper) before the outsole is applied to the shoe. In some aspects also the invention has more particular reference to ironing means for use in the manufacture of shoes in which the upper is secured to the insole by an adhesive, and it may be also in which the outsole is thereafter secured adhesively o-n the shoe bottom, although it is to be understood that the invention is not thus limited in its applicability. The invention is illustrated herein as embodied in a machine of the type disclosed in United States Letters Patent No. 1,951,3'7 3, granted March 20, 1934, upon an application led in my name, but it is to be understood that the invention is not limited to machines of that type.

In the illustrated machine there is provided, in accordance with a feature of the invention, a novel construction and arrangement of means for ironing the marginal portion of an upper previously laid inwardly over an insole substantially in lasted position, along the sides of the shoe in locations between the toe and heel-end portions of the shoe and also around both ends of the shoe, although it is to be understood that the invention is not limited to means for thus ironing the upper at both ends of the shoe. In the construction shown the ironing means comprises side-ironing members extending along the opposite sides of the shoe in locations between its toe and heel end portions, end-ironing members mounted for swinging movements laterally of the shoe each about an axis substantially midway between the opposite sides of the shoe, and other ironing members extending between the end members and the side members, the several members being heated and arranged to support a shoe placed thereon bottom downward. As illustrated, the end members are movable lengthwise of the shoe and the side members laterally of the shoe in wiping engagement with the upper in response to pressure of the shoe upon them, through the action of pairs of parallel links of equal lengths which are eiective, as the pressure is applied, to move the members inwardly over the shoe bottom without varying their relative positions heightwise of the shoe. Spring means is further provided fo-r yieldingly opposing the inward movements of the several members and for progressively increasing the pressure of the members on the upper during their inward movements, the

pressure of the members being further increased after they have completed their inward movements. In accordance with a further feature,

a novel construction is provided whereby the swinging or closing movements of the end mem- 5 bers laterally of the shoe are effected by the side members. As illustrated, there are utilized for this purpose the above-mentioned ironing members that extend between the end and side members, these ironing members receiving their opl0' erative movements from the end and side members.

In the illustrated machine there is provided, as in the machine of the above-mentioned Letters, Patent,- means for preventing outward return 15 movement of the side-ironing means or members until after the shoe has been substantially released from pressure, so as to avoid any possibility of displacement of the margin of the upper by outward drag of the members thereon. In 2m order to prevent outward movement of the endironing means in advance of the side-ironing means there is provided, in accordance with a further feature of the invention, novel means arranged to permit the end-ironing means to T;v move outwardly only with the side-ironing means.

It is contemplated that such ironing means may be used with substantial advantages in operating upon shoes the opposite sides of which 3'05 have been previously lasted, for example by use of a machine of the character disclosed in United States Letters Patent No. 1,943,344, granted January 16, 1934, upon an application filed in my name, and in which the uppers 3'5? are held in lasted position by an adhesive which has hardened or set sufliciently to prevent any loss of lasting tension, and yet is more or less yieldable under the application of heavy pressure. By the ironing means described the marginal portion of the upper is flattened against the insole and smoothed free from wrinkles by the inwardly moving heated members, which may also draw 'it more tightly inward over the insole. The application of increased pressure and heat to the margin of the upper at the completion of the ironing operation also tends to set the margin of the upper in its ironed-out condition vso that when the shoe is nally released from pressure it will be provided with a bottom surface best fitted for the reception of its outsole. Iny operating on shoes of that type in which the outsole is secured by an adhesive it is further contemplated that the Several ironing members may be provided with serrated upper-engaging faces so that by their pressure on the margin of the upper, and especially the nal pressure after the completion of their inward movements, they will produce a large number of indentations in the surface of the upper to facilitate the roughening of the upper to receive cement for the attachment of the outsole, and in this aspect of the invention there is to be recognized a novel method as well as novel means. It is further to be understood that in the novel construction and.

arrangement of wiping means, the invention, in various novel aspects, is not limited to use on shoes in which the marginal portionrof the upper has been previously laid inwardly over an insole.

The above and other features of the invention, inciuding novel means for adjusting the ironing members and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

This invention is illustrated as applied to a machine organization which is in many respects similar to that illustrated in Letters Patent of the United States No. 1,549,243, granted on August 11, 1925, upon an application of E. E. Winkley, with portions of the machine constructed as disclosed in Letters Patent No. 1,951,373 above mentioned, although it is to be understood that the invention is not limited to organizations of that particular character. Machines of the type illustrated in said Letters Patent No. 1,549,243 are twin machines comprising two sets of mechanisms whereby one shoe is subjected to pressure simultaneously with the release from pressure of another shoe previously operated upon. Only one of the two sets of mechanisms is herein illustrated or need be referred to for an understanding of the present invention. As more fully illustrated in the above-mentioned Letters Patent No. 1,549,243, the machine is provided with a pair of vertical rods 20, one of which` is shown in Fig. 1, which support adjustably near their upper ends a cross-head (not shown). To this cross-head there are adjustably secured a toe post 22 and a heel post 2d which serve to support the shoe against upwardly directed pressure applied on its bottom face. The toe post 22 has a rubbercovered roll 26 thereon for engaging the shoe or last on the tcp of the forepart, and the heel post is provided with a plate 28 arranged to engage the top face of the heel-end portion of the last, the plate 28 being mounted on a block 38 pivotally connected at 32 to the heel post and arranged to be swung about its pivot by an adjustable screw 34 against the action of a flat spring 36 to adjust the plate 28 so that it will bear evenly on the top face of the last, as more fully disclosed in said Letters Patent No. 1,951,373 referred to above.

Mounted on the rods 26 is a slide 38 to which upward and downward movements are imparted through a link 4) connected at 52 to the slide and other mechanism not herein shown in detail since it is fully disclosed in the Letters Patent No. 1,549,243 above mentioned. The slide 38 supports a box 44 provided with a pair of trunnions, one of which is indicated at 46, Fig. l, mounted in bearings on the slide so that the box may tip about an axis extending laterally of the shoe, the box being held normally in a predetermined position,

determined by a spring-pressed plunger 48 carried by the box and engaging the slide, by a spring 58 connecting the slide and the box.

Vertically movable in the box 411 is a casting 52 supported by four springs 54 which are yieldable in response to resistance of the shoe to the pressure applied. Mounted in guideways on the casting 52 for movements in directions widthwise of the shoe is a slide 56 which is adjustable along the guideways by means of a screw 58 held against lengthwise movement by a lug 69 fast on the casting. Mounted in guideways on the slide 56 for movements in directions lengthwise of the shoe is a slide 62 (Fig. 3) which is adjustable along the guideways by means of a screw 64 held against lengthwise movement, relative to the slide 62, by a plate 66 fast on the slide 62, the screw being threaded in a lug 68 on the slide 5S and having a hand wheel 'i0 thereon for turning it. The slide 62 serves as a support for four brackets 72, two of which are located opposite each other near the toe end of the shoe and the other two of which are located opposite each other near the heel end of the shoe. The brackets 'l2 are connected to corresponding blocks l5, (Fig. 3), which are movable in directions widthwise of the shoe in recesses in the slide 62, in the same manner as in the machine of Letters Patent No. 1,951,373, above referred to, the connections being such as to permit each bracket 72, while movable widthwise of the shoe with its connected block, to swing about a vertical axis. The means for adjusting the blocks and with them the brackets 12 laterally of the shoe is not shown herein in detail since it is fully shown and described in Letters Patent No. 1,951,373 abo-ve mentioned. The two blocks mounted near the toe end of the shoe are connected by a shaft 'i4 which is mounted in bearings on the slide 62 and has rightand left-hand threads thereon engaging the blocks and a hand wheel l secured to its outer end for turning it to adjust the blocks toward or from each other. The two blocks near the heel end of the shoe are connected by a shaft 18 (Fig. 1) also mounted in bearings on the slide 62 and provided with rightand left-hand threads engaging the blocks. The shafts lll, 'i8 are turned simultaneously by the hand wheel 16 through connections including pinions 89, 82 secured respectively to the shafts 1li, 'i8 and engaging a rack bar 84 supported on the slide 62.

Connected by parallel links 86, 88 to each of the brackets i2 (Fig. 3) is an angularly shaped holder 90, and each pair of similarly arranged holders serve to support a metal block 92 on which is mounted one of a pair of ironing members or wipers 94, 96. As shown particularly in Figs. 1 and 2, the ironing members 94, 96 extend along the opto support a metal block |30.

posite sides of the shoe between its toe and heel end portions and are shaped both heightwise and widthwise of the shoe to conform substantially to the curvature of the edge of the shoe bottom'. The

` blocks 92 are positioned and secured on the holders 90 by dowel pins 98 which project upwardly into recesses formed in the blocks and by spring controlled plungers which are movably mounted in the holders 90 and are controlled by handles |02 by which they may be withdrawn from recesses formed in the sides of the blocks to permit the blocks to be lifted from the holders. Each of the ironing members 94, 96 has a tongue-andgroove connection |04 with its supporting block 90 to maintain it in the proper lateral position and is held in proper lengthwise position by means of a dowel pin |06, Fig. 3, which projects from the block into a recess in the ironing member. As thus mounted, the ironing members 94, 96 may be readily removed simply by lifting them from the blocks 92 when it is desired to substitute different members for use on shoes of widely varying sizes or styles.

Each parallel link 86 has an extension |08, Fig. 3, provided with a slot through which extends a rod |0 pivoted at its lower end to the bracket 12, and encircling this rod is a spring ||2 which bears at its lower end against a washer ||4 that rests against the extension |08 and at its upper end on a wing nut |6 threaded on the rod. The springs ||2 by their actions on the links 86 thus tend to maintain the holders 90 in elevated positions with the outer side faces of the holders against the upwardly extending portions of the brackets '|2. It will be understood that the ironing members 94, 96 may be adjusted toward or from each other by means of the hand wheel 16 to accommodate shoes of diiferent sizes, and in order to take care of variations in widths between theV foreparts and heel ends of shoes of different sizes the shaft 14 may be and preferably is provided with threads of steeper pitch than the threads on the shaft 18 so that greater movements toward or from each other are imparted to the portions of the ironing members that are nearer the toe end of the shoe than to the portions near the heel end by the same movement of the hand wheel 16. Conveniently also the hand wheel 16 may be provided with a flange |8 which has size indications thereon arranged to cooperate with width indications marked on the adjacent surface of the slide 62 as a guide in adjusting the ironing members. As thus far described the machine herein shown is constructed substantially as disclosed in Letters Patent No. 1,951,373, abovementioned.

Located opposite each other, one at each end of the shoe, and secured to or formed integral with the slide 62 are a pair of brackets |20, Figs. l and 4. Each bracket |20 is provided with an angularly shaped upper portion |22 to which there is connected by pairs of parallel links |24, |26, a similarly shaped holder |28 which serves Each metal block |30 is positioned and secured on its holder |28 by a dowel pin |32 which extends into a recess in the block |30, and mounted on the upper surface of each block |30 is a slide |34.

Each slide |34 is adjustable on its supporting block |30 in directions lengthwise of the shoe by a screw |36 which is held against lengthwise movement relative to the slide |34 by a lug |38 on the slide engaging spaced shoulders on the screw, the screw being threaded into the block |30 and having a hand wheel |40 thereon for turning it.

Each slide |34 carries an upwardly extending pin |42 arranged to be located substantially midway between the opposite sides of the shoe, and pivotally connected to each pin |42 is a pair of endironing members or wipers |44, |46, Figs. 4, and 6. The end-ironing members |44, |46 are provided with guideways |48, |50, and slidably mounted in the guideways and pivotally connected respectively at |52, |54 to the side-ironing members 94, 96 are additional ironing members or wipers |56, |58 which extend in directions lengthwise of the shoe along the opposite sides of the ends of the shoe between the side-ironing members 94, 96 and the end members |44, |46.

By reference to Fig. 4 is will be seen that the upper surface of the block |30 at the toe end of the shoe is inclined so that the end-ironing members |44, |46 and the ironing members |56, |58 at that end of the shoe are supported atthe proper angle to permit them to iron the overlaid margin of the upper around the toe end. Each slide |34 has a cover plate |59, Figs. 2 and 4, which overlies the end-ironing members |44, |46 and the ironing members |56, |58, and each cover plate is cut away as shown to receive an end of the shoe.

One of each pair of parallel links |24, |26, namely the link |24, has an extension |60 provided with a slot through which extends a rod |62 pivoted at its lower end to the upper portion |22 of the bracket |20, and surrounding this rod is a spring |64 which bears at its lower end against a washer |65 resting against the extension |60 and at its upper end against a wing nut |66 threaded on the rod. The springs |64 act through the links |24 to hold the members |28 initially in their uppermost positions with the outer side faces of the holders 28 against the upwardly extending portions |63 of the brackets |20. It will be understood that when the machine is initially at rest the springs ||2, |64 act on the links 86, |24 to present all the ironing members in upraised positions. As thus presented the ironing members are arranged to receive and support a previously lasted shoe placed initially thereon bottom downward, and preferably the ironing members are so adjusted relatively to one another that they will engage the overlaid margin of the shoe upper around the entire periphery of the shoe bottom. By reference to Figs. 5 and 6 it will be seen that by rotation of the hand wheels 16, |40 the side members may be adjusted laterally of the shoe and the end members |44, |46 and the members |56, |58 both lengthwise and laterally of the shoe to accommodate shoes of diiTerent sizes. When pressure is applied to the bottom of a shoe by the ironing members in the upward movement of the slide 38 after the shoe has been moved'intoengagement with the members 26, 28, the resistance of the shoe to upward movement of the ironing members causes the parallel links 86, 88 and the parallel links |24, |26 to swing from their initial positions into positions such as indicated in Fig. 4 and thus to move the ironing members 94, 96 and the ironing members |44, |46 bodily inward over the shoe bottom in response to the pressure of the shoe on the members to iron the overlasted margin of the upper along the sides and at the ends of the shoe.

As the side-ironing members 94., 96 move inwardly they act to swing the members |56, |58 inwardly and thus to impart to the end members 44, |46 swinging or closing movements laterally of the shoe. Furthermore, by reason of the sliding connections between the end members and the members |56, |58, additional inward swinging movements are imparted to the members |56, |58 about their pivotal connections to the side members as the end members move bodily inward. The members |56, |58 are thus carried bodily inward to iron the marginal portion of the upper along the sides of the ends of the shoe inwardly over the insole by the inward movements of the end and side members. It will be understood that the inward movements of the ironing members are effected against the increasing resistance of the springs 12, 164 through which the ironing members are pressed against the shoe during the ironing operation, so that the pressure of the members on the shoe bottom progressively increases. The swinging of the parallel links is limited by engagement of the holders 98, |28 with their respective brackets 12, |28, after which still greater pressure is applied to the shoe through the springs 54. The holders 9S, |28 are positioned initially equal distances above their respective brackets 12, |28, and in order that the different ironing members will be maintained substantially in theV same relative heightwise positions at all times the parallel links |28, |26 for connecting the holders |28 to the brackets |26 and the parallel links 85, 88 for connecting the holders .18 to the brackets 12 are of equal lengths. in order to insure that the margin of the upper will be flattened evenly against the insole around the entire bottom of the shoe it is desirable that the different members exert substantially the same amount of pressure on the different portions of the margin of the upper as they move relatively to one another inwardly over the shoe bottom in response to pressure of the shoe upon them. Accordingly the different springs |12, 16d have substantially the same capacity and are preferably so adjusted that they are held under the same initial tension by the Wing nuts |66, |66. As the ironing members move inwardly equal movements of compression are imparted to the dierent springs |12, |66 by the equal links 86, |24, so that the pressure of the different ironing members on the upper is substantially the same at all times.

In order to assist in ironing the overlasted margin of the upper free from wrinkles and setting it in lasted position the illustrated machine is provided with means for maintaining the ironing members in a heated condition. For this purpose the blocks 92, 136 are heated by electrical heating units |16 mounted as shown in recesses in the blocks, and each unit |18 is connected by suitable electrical connections to any convenient source of electrical energy for heating it. From the blocks 82, |30 the heat is conducted to the ironing members mounted upon them.

The illustrated machine is further provided With means which is substantially the same as that shown in Letters Patent No. 1,951,373 above mentioned for preventing return of the side-ironing members 94, 96 totheir initial positions in the downward movement of the slide 38 until after the shoe has been substantially released from pressure. This means comprises a latch |14 at each end of the slide 62, Fig. 1, fast on a rock shaft |16 mounted in bearings on the slide. Each latch is arranged to be spring urged inwardly into position to catch on projections |18 on the two holders 98 when the holders have been lowered in the ironing operation far enough to carry these projections below the latch. For moving the latches out of engagement with the projections there' is fast on the end of each rock shaft an arm |88, and pivotallyconnected to the arms |86 is a rod |82 which extendsrupwardly and passes loosely through an opening in a block |84 fast toone of the rods 26. The rod |82 has threaded on its upper end a nut |86, the construction being such that when the slide 38 is lowered far enough to carry the shoe away from the shoe-supporting members 26, 28 the nut |86 engages the block |84, after which as the slide continues to move downwardly the latches |14 are swung out of engagement with the projections |18 to permit the holders 90 to swing upwardly and outwardly. For preventing return of the end-ironing members to their initial positions until after the shoe has been substantially released from pressure, there are provided connections between the end and side-ironing means arranged to prevent return of the parts of the end-ironing means to their starting positions until the latches |14have released the holders 98 to the action of the springs ||2. As shown, these connections comprise pins |88 (Fig. 4) carried by the blocks |30 and arranged to extend into slots |96 formed in the blocks 92. It will be understood that the pins |88 extend into the slots |98 to a depth suihcient to permit' the blocks 92, |36 to complete their relative movements lengthwise of the shoe without moving the pins out of engagement with the slots 92 and that the slots extend far enoughy laterally of the shoe to permit the required relative movement of the blocks laterally of the shoe.

The machine herein shown, is further provided with gaging means, substantially like that disclosed in Letters Patent No. 1,951,373 referred to above, to determine -the proper lateral position of a shoe on the ironing members. This means comprises gages |92 located at the opposite sides of the fo-repart of the shoe and other gages |94 located at the opposite sides of the heel end. Each of the forepart gages comprises a metal plate |96 bent into the shape illustrated in Fig. 3 and provided with a covering of soft material such as leather or rubber arranged to contact with the shoe. Each plate is mounted on a block 280 for free turning movement about a Vertical axis to permit it to adjust itself to the contour of the shoe and each block 288 is swivelled on the end of a screw 282 which is threaded in an upright supporting arm 264. The two arms 264 are mounted in a guideway extending laterally of the shoe in a plate 265 secured to the slide 62 and are adjustable toward or from each other by a shaft 266 which has right and left threads engaging the respective arms and is provided with a knurled head 288 for turning it. The shaft 206 is held from lengthwise movement by collars 2|6 which are fast thereon at the opposite sides of a plate 2|2 secured on the supporting plate 265. The gages |92 are thus adjustable simultaneously toward orl from each other by the shaft 266 and are also adjustable each independently of the other by the screws 262 for properly positioning shoes of different sizes and styles. The gages |94 at the heel end of the shoe (Figs. 1 and 2') consist of arms mounted on a block 2|4 for swinging movements toward or from each other at the opposite sides of the heel end of the shoe and connected by gear teeth 2|6 to swing in unison, each arm having a leather cover 2|8 thereon to oo-ntact with the shoe. The two arms |96 are adjusted toward and from each other by a shaft 228 having right and left threads in engagement with blocks 222 that are swivelled on the outer ends of the respective arms, the shaft having va knurled head 224 thereon for turning it. The supporting block 2|4 is pivoted at 226 on a standard 228 which is mounted on the casting 52 so that the arms |94 may be swung out of operative position to facilitate the removal of the ironing members 94, 96. A spring 230 connected to one of the arms |94 and to the standard 228 holds the arms normally in operative position, the arrangement of this spring and its relation to the axis 22B-being such that it will also maintain the arms in inoperative position when they are swung to that position.

In order to insure the application of adequate ironing pressure on the upwardly sloping portion of the shoe bottom immediately at the rear of the ball of the shoe by the complementally shaped portions of the ironing members 94, 96 it is contemplated that the roll 26, as illustrated, will be so adjusted as to engage the shoe or last on its upwardly inclined top face at the rear of the toe and thus effect somewhat of a rearward displacement of the shoe as the pressure is applied so as to force it hard against the abovementioned portions of the ironing members. It will be evident that the plate 28 engaging the top of the heel end and the last does not prevent such rearward movement of the shoe.

Instead of providing the several ironing members with smooth upper-engaging surfaces such as shown in Figs. 2, 5 and 6, it is contemplated that the several members may have serrated upper-engaging faces, so that by their pressure upon the shoe bottom, and especially the final pressure after the completion of their inward movements, they will produce a large number of indentations in the surface of the upper. This will facilitatev the roughening of the upper to receive cement if an outsole is to be attached to the shoe by cement, since a roughening tool such as commonly used will act more readily and effectively upon the upraised portions of the upper between the indentations than it would upon an upper having a continuous smooth surface. Portions of ironing members 96 and |58 having such serrated faces are shown in Fig. 9.

In the operation of the machine, briefly summarized, after the ironing members 94, 96 and the ironing members |44, |46 have been adjusted properly for the size of the shoe to be operated upon and have beenheated to the desired temperature, the operator places a previously lasted shoe bottom downward on that set of ironing members which is in its lowermost position in the machine and locates the shoe lengthwise in the machine by the complementally shaped ironing members 94, 96, and laterally of theV machine by adjustment of the gages |92, E94. While the invention is not limited to use on shoes of the particular kind illustrated, the shoe herein shown is one in which the margin of the upper along the sides and around both the toe and heel ends of the shoe is secured in lasted position by an adhesive and in which an outsole is thereafter cemented to the lasted margin of the upper. Before the shoe is presented to the machine the sides of the shoe may have been lasted by use of the machine of Letters Patent No. 1,943,344 above mentioned, and the ends of the shoe in any suitable well known manner as by use of a bed-lasting machine.

Y After placing a shoe in position to be operated upon, as above described, the operator then starts the power operation of the machine, whereupon the slide 38 at that side of the machine where the shoe was placed is elevated and the slide at thel other side is lowered. The shoe is accordingly raised until stopped by the abutments 26, 28, and when this occurs the pressure of the bottom of the shoe against the side-ironing members 94, 96 and the end members |44, |46 causes the links 86, 88 and the links |24, |26 to swing from their initially inclined positions, Fig. 3, to positions more nearly horizontal, Fig. 4, as the supporting brackets 72, |29 continue their upward movements, so that the ironing members are forced inwardly over the shoe bottom in wiping engagement with the marginal portion of the upper, the end members |44, |46 being closed inward laterally of the shoe by the action of the side members 94, 96 thereon through the connecting members |56, |58. It will be understood that such movement of the ironing members occurs only after the pressure ofthe shoe upon them is great enough to overcome the resistance of the springs H2, |64 which are further compressed as the ironing members continue to move inwardly and therefore subject the upper to progressively increasing pressure during the ironing operation. The ironing members as they move inwardly over the insole thus tend to draw the upper around the entire peripheries of the shoe inward over the insole as they apply progressively increasing pressure heightwise of the shoe and heat to the margin of the upper to flatten it against the insole and to eliminate any wrinkles. The inward wiping action of the ironing members is terminated by engagement of the holders 90, |28 with the brackets 12, |20 respectively and thereafter the upper is subjected to further pres-v sure through the springs 54 and the heavy togglecontrolling spring with which machines of this type are provided. In the ironing operation the roll 3i] acts on. the sloping face of the shoe or last to effect more or less of a rearward displacement of the shoe such as to insure effective pressure on the margin of the upper along that portion of the shoe bottom which slopes rearwardly from the ball of the shoe. The machine comes automatically to a stop with the shoe under pressure and while the shoe is held under pressure the operator presents a shoe to the other half of the machine. As the slide 38 is lowered to release the shoe the latches |74 prevent upward and outward swinging movements '0f the holders 96 under the infiuence of the springs H2 until after the shoe has been carried downwardly away from the abutments 26, 28 and. thus releasedv from pressure, the holders |28 being also held against upward and outward swinging movements under the influencey of the springs |64 in advance of the holders 90 by reason of the pin-and-slot connections between the blocks 92, |39. Near the end of the downward movement of the slide 38 the latches are operated to release the holders, thus rendering the springs ||2, |64 effective to return the ironing members to their starting positions. Since the shoe rests merely by its own weight on the ironing members at that time, there is no danger of any displacement of the margin of the upper by the outward movement of the ironing members.

If the machine is provided with ironing members having serrated upper engaging faces as shown in Fig. 9, a large number of indentations will be formed in the surface of the overlaid marginal portion of the upper as the ironing members are forced with increased pressure against the upper at the completion of their inward movements. The indentations thus produced not only facilitate the roughening of the overlaid margin of the upper, but also serve to indicate clearly that portion of the margin to be roughened preparatory to the laying of. the cement-coated outsole thereon.

Fig. 8 shows the bottom of a shoe as it appears after it has been operated upon by the machine when the machine is provided with ironing members having smooth faces. It will be understood that any objectionable wrinkles in the margin of the upper are eliminated as the upper is ironed inwardly and pressed smoothly against th-e insole along the sides and around the ends of the shoe. The shoe is thus provided with a bottom surface best tted for the reception of its outsole.

It is to be understood that the inventio-n is not -limited to a machine that irons the margin of the upper at both the toe and heel ends of a shoe nor that operates along both the forepart and the shank portions of the shoe bottom; and that it is also not limited to use on shoes the uppers of which are fastened in lasted position by an adhesive.
