30 Claims.

This invention relates to means for operating. on shoes in the course of shoe manufacture, and is herein illustrated as embodied in means constructed particularly forum in operating on the toe ends of shoes, although it is to be understood that the invention is not thus limited, but is also applicable, for example, to means for use on the heel ends. r

It has been proposed heretofore to subject the marginal portion of the toe end of an upper, after it has been wiped inwardly over an insole by the Wipers of a lasting machine, to the action of a heated pressing or ironing device to smooth the overwiped margin free from wrinkles and to press it fiat upon the insole, as disclosed, for example, in United States Letters Patent No. 1,951,- 374, granted on March 20, 1934 upon an application of C. F. Pym. In lasting toes with an adhesive such a device is particularly useful, not only because of its smoothing and compacting effect on the upper, but also by reason of the fact that the heat tends to accelerate the drying or hardening of adhesive of the character commonly used in lasting, thus insuring that the upper will be securely held in final lasted position without the necessity of attaching to the shoe any temporary upper-retaining means, In accordance with the disclosure of the above-mentioned Letters Patent the heated pressing or ironing device, after'it has been applied to the margin of the upper, is moved lengthwise of the shoe with a wiping action on the upper by pressure of the toe-lasting wipers thereon to render it more effective in smoothing or ironing the upper as well as to insure that the upper in its final position will extend tightly over the extreme edge of r the insole.

' The present invention, in one aspect, provides improved means whereby the overlaid'marginal portion of an end of an upper is subjected to an inward wipe laterally of the shoe as well as lengthwise of the shoe in the pressing or ironing operation, thus affording increased insurance that in its final lasted position the upper will lie smooth and flat upon the insole and will extend tightly over the edge of the insole all around the end portion of the shoe bottom. For the purpose in view, the construction herein shown'comprises a pair of heated pressing or ironing members curved to extend around the toe end of the shoe bottom and mounted to swing relatively to each other laterally of the shoe as well as to move bodily lengthwise of the shoe in response to pressure of the wipers upon them. In the form illustrated these members are so constructed as to extend throughout the length of the forepart of the shoe so as to operate on the margin of the upper not only at the toe portion but also as far rearwardly as the ball line. As herein disclosed, the ironing members may be mounted on a support whereby they are carried into and out of position over the shoe bottom, or alternatively the members may constitute a portable ironing device pressed upon the shoebottom by means which contacts therewith.

The above and other features of the invention, including 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.

Fig. 10 is a perspective view of a heated ironing member mounted on the machine for use in ironing portions of the margin of the upper not acted upon by the illustrated forepart ironing means.

The bed-lasting machine portions of which are herein shown is one of a well-known type characteristic features of which, relating especially to the means for lasting the toe end of the shoe, are described in detail, for example, in Letters Patent No. 1,284,870, granted on November 12, 1918 upon an application of Matthias Brock. Only such parts of the machine, therefore, as it is necessary to refer to for an understanding of this invention are hereinafter mentioned. It is further to be understood that the invention is not limited to machines of the particular type illustrated. V

The machine is provided with a heel-end support comprising a spindle 56 arranged to enter the spindle hole in the heel end of a last and with a toe rest !2 for supporting the forepart of the shoe and last. The shoe thus mounted is engaged by a heel band M which clamps and holds its heel-end portion and serves to maintain its toe end pressed firmly down upon the toe rest 12. For wiping the toe-end portion of the upper heightwise of the last and for wiping its margin inwardly over an insole on the last there are provided toe-embracing wipers l6 which are moved bodily lengthwise of the shoe and are swung inward laterally of the shoe by mechanism operated by a hand lever l8. Controlled by the same hand lever is a toe band 20 which embraces and clamps'the upper around the toe near the edge of the shoe bottom, this band being pressed against the upper as the wipers begin to wipe the upper inwardly over the insole. While such a toe band is herein shown, it may be and often is omitted from the machine. The toe-lasting means, including the wipers l6 and the toe band 20 when the latter is used, are supported on a vertically movable slide 22 connected by a link 24 to a double-acting treadle 26 whereby the operatoris enabled to raise the wipers for wiping the upper upwardly around the toe and to force them down upon the shoe bottom during or after their inward wiping movements.

For purposes of this invention the machine is provided (Figs. 1 and 2) with a heated pressing or ironing device comprising a pair of ironing members 28 curved in general similarity to the curvature of the edge of the toe end of the shoe bottom and connected together by a hinge joint to swing relatively to each other laterally of the shoe about an axis extending heightwise of the shoe and located approximately at the end of the toe. The manner in which the two members are thus connected is illustrated sectionally in Fig. 5, the members having portions which overlap each other in a plane perpendicular to the axis of their swinging movements with the overlapping portion of one of the members pivoted on an upstanding sleeve 36 formed on the other member. It will be understood that the interconnected parts of the two members are so formed that the lower upper-engaging faces of the members are continuous around the end of the toe. In the. construction shown the members 28 are so elongated as to extend at least throughout the length of the forepart of the shoe so as to act on the margin of the upper not only around the toe portion but also as far rearwardly as the ball line. Between the members 28 is a spring 32 seated in recesses in the members and tending to swing them apart, their swinging movements under the influence of the spring being limited by interengaging lugs 33 formed on the two members near the hinge joint. Mounted in the members 28 are electrical heating units 36 to which electrical-current is conducted through flexible cables 38. Threaded at its lower end in the sleeve 38 (Fig. 5) is an upwardly extending rod ll] on which is mounted a handle 42 which may be made of wood to enable the operator more readily to position the members 28 in proper relation to the shoe. It will be understood that the wooden handle will remain in a substantially unheated condition, so that there will be no danger of burning the operators hand. Between the lower end of the handle 52 and the members 28 is a collar 44 formed of material which is a relatively poor conductor of heat to insure further against burning the Wood of the handle.

As shown in Figs. 1 and 2, the. ironing members 28 are supported on one endof an arm or carrier 46 which is slidingly movable lengthwise in a holder 48 supported on a vertical rod 50. This supporting means and its operating mechanism in the machine herein shown are of substantialiy the same construction as means provided heretofore in machines of the illustrated type for supporting 5 a holddown member and for pressing the member upon the shoe bottom, as disclosed in Letters Patent No. 1,120,822, granted on December 1914 upon an application of E. L. Keyes. As

more fully illustrated therein, the rod 5% is connected by a link 52 to a treadle 54 which is normally held in upraised position by a spring 56 and is locked in depressed position by mechanism not herein shown in detail but controlled by a releasing member 58. The holder 48 is mounted to turn about the rod 50, and by means of a spring 66 is held normally (Fig. l) in a position in which the arm 46 extends lengthwise of the shoe at the rear of the machine, so that the ironing device, mounted on the arm in a manner hereinafter described, is at that time retracted from over the shoe bottom when a shoe is positioned in the machine. Between the holder 48 and the rod 52 is a connection comprising a spiral slot 52 in the holder and a pin 64 on the rod, as in the construction shown in the last-mentioned Letters Patent, so that as the arm 46 is swung forwardly to carry the ironing device to a position over the forepart of the shoe bottom the arm is lowered to bring the device close to the shoe bottom. In the construction herein shown a lever 66 is pivotally mounted on the arm 46 and has a pin-and-slot connection with the holder 48 so that the operator may conveniently slide the arm forwardly or rearwardly at any time to assist in positioning the ironing device. in proper relation to the shoe. Ordinarily the arm is maintained in any position to which it is moved by the lever by reason of the friction between the arm and the holder. It will be understood that after the ironing device has been moved to the proper position over the shoe bottom it is forced down upon the margin of the upper by depression of the treadle 54.

The ironing members 28 are supported on the arm 46 through a crossbar 68 mounted for universal tipping movements relatively to the arm. For this purpose the arm carries a stud H3 having a lower ball-shaped end 12 mounted in a socket formed partly in the crossbar and partly in a plate 14 which is fastened to the crossbar.

Formed in the crossbar 68 are two curved slots 16 which are concentric with'the axis of relative swinging movements of the members 28 and through which extend studs 18 threaded at their crossbar the members are pressed down upon the shoe bottom by the downward movement of the arm 46. It will be understood that the above described'connections between the crossbar and the members 28 permit the members to swing toward or from each other laterally of the shoe 'and that by reason of the provision for universal tipping movements of the crossbar the members adjust themselves to the shoe bottom and apply substantially equal pressures to all portions of the margin of the upper which they engage.

In the use of the machine constructed as thus far described, the operator, in accordance with one well-known procedure herein illustrated in lasting toes with adhesive, first wipes the upper materials upwardly around the toe end of the last by raising the wipers l6 through the treadle 26 while holding them pressed inwardly against the upper by the hand lever I8, and then by further movement of the hand lever advances and closes the wipers to wipe the marginal portion of the several layers of upper materials initially inward over the insole, as shown in Fig. 3. Thereafter he retracts the wipers from over the shoe bottom, removes the surplus margin of the lining and the toe box by means of a hand knife, applies a suitable adhesive to the margin of the toe end of the insole or the margin of the outer layer of the upper materials or both, and then again wipes the upper upwardly around the toe and wipes the margin of the outer layer of the upper materials inwardly over the insole (Fig. 4) into position to be secured to the insole by adhesive. Before the shoe is presented to the machine it may, as illustrated, have been previously lasted along the shank portion and the upper fastened in lasted position in that location by staples s, although the utility of the present invention is not dependent upon the fastening of the shank portion of the upper by this particular means nor upon the previous lasting of the shank portion. In accordance with a frequent practice, moreover, the upper may have been previously lasted also from the ball line forwardly as far as the toe portion and the upper fastened in lasted position in that location by use of an adhesive. If this has not been done, the operator may last the sides of the shoe manually from the ball line forwardly to the toe portion while the shoe is in the bed-lasting machine, preferably using an adhesive to fasten the upper to the insole.

After wiping the margin of the toe portion of the upper inwardly as shown in Fig. 4, and it may be also after having lastedthe sides ofthe upper between the toe portion and the ball line as above described, the operator withdraws the Wipers from over the shoe bottom, and by means of the handle 42 swings the ironing members 28 into position over the forepart of the shoe bottom, using the lever 66, if necessary, to assist in the shoe. He then depresses the treadle 54 to force the ironing members down uponv the over lasted margin ofthe upper, the members preferably being positioned at this time substantially as illustrated in Figs. 5 and 7 with portions thereof extending outwardly beyond the edge of the shoe bottom. It will be understood that the ironing members constructed as shown thus en-' gage the upper all around the toe end of the shoe bottom and throughout the length of the forepart of the shoe. While thus pressing the ironing members 28 downwardly by means of the treadle 54, the operator raises the toe Wipers 16 by the treadle 26 and advances and closes them by the hand lever l8 to engage their edges with the ironing members in the manner illustrated in Fig. 5, and then by further movement of the hand lever operates the wipers to force the ironing members inward both lengthwise and lat.- erally of the shoe as illustrated. in Figs. 6 and 8. It will be understood that the arm A6 swings to permit the members to move lengthwise of the shoe. In this manner the overlasted margin of the upper is'subjected to an inward wipe both lengthwise and laterally of the shoe while being pressed downwardly and heated, thus insuring that the upper will be drawn tightly over the edge of the insole and that its margin will be pressed smooth and flat upon the insole.

After having thus operated the ironing members 28, the operator returns the toe wipers to their starting positions. It will'be understood that the ironing members will be thereafter maintained in pressure-applying relation to the upper by the previously mentioned locking means associated with the treadle 54, the heat of the members causing the adhesive rapidly to dry or harden. At such time as the operator determines the member .58 controlling the locking means is operated to release the'ironing device and it is then Withdrawn from the shoe and returned to its idle position. The device may be left in contact with the shoe while the operator lasts the heel end of the shoe in the customary manner, if the heel end has not already been lasted, al-

though when a quick-drying adhesive is used the device need not be maintained in contact with the upper for any substantial length of time after its inward movement over the shoe bottom. It will be understood that such an adhesive will, of itself, hold the overlasted margin of the upper to the insole in the interval between the withdrawal of the wipers and the placing of the ironing device on the shoe, the heat of the ironing device thereafter further hardening the adhesive and thus affording increased insurance against any later displacement of the upper from final lasted position.

' In Fig. 9 is illustrated an alternative construction in which the ironing device is not supported on the arm 45 but is a portable device which.

however, is pressed down upon the shoe bottom by the arm 46 and is moved inwardly over the shoe bottom by the wipers IS in the same manner as above described with reference to the device shown. in Fig. 2. The ironing device-shown in Fig. 9 comprises ironing members 28 having plane upper faces engaged by a crossbar 68' which is supported on the arm 46 in the same manner as the previously described crossbar 68. The members 28'; like the membersr28 previously described, are each so formed as to extend substantially throughout the width of the overlaid margin of the upper in operating as shown upon a shoe of the type in which the margin lies throughout its width substantially parallel to the bottom of the last. In other respects the construction shown in Fig. 9 is the same as that shown in Fig. 2. It will be understood that by means of a handle 42 like the previously described handle 42 the operator places the members 28' in proper position upon the shoe bottom and that the crossbar 68' is thereafter swung to a proper position over the members and is operated by the treadle 54 to press the members down upon the shoe bottom. By the same handle the operator removes the members from the shoe after the ironing operation. The portable ironing device shown in Fig. 9 is placed, when not in use, upon any suitable support where it is maintained in heated condition by the electrical heating means. The device may, of course, be heated by any suitable means not portable therewith, instead of by the electrical means illustrated.

In Fig. is shown an ironing tool 84 suitably shaped to operate, if conditions render it desirable to do so, upon portions of the lasted margin of the upper which are not operated upon by the previously described ironing means; for example, upon the margin of the upper along the shank portion of the shoe bottom to smooth and flatten the margin over the insole. The tool 84 is fast on a bracket 86 secured to the front of a casting 88 which carries the toe wipers, and the tool is maintained in a heated condition by an electrical heating unit 90 therein. It will be understood that after removing the shoe from its support in the lasting machine the operator may place the bottom of the shoe in contact with the ironing tool 84 and move the shoe along the tool to iron the margin of the upper as desired.

Since the invention is not limited to use in the manufacture of shoes of the particular type illustrated, the term sole is used in the appended claims in a generic sense to refer to the shoe bottom part over which the margin of the upper is lasted.
