41 Claims.

This invention relates to the manufacture of shoes and, in some of its aspects, more particularly to the manufacture of shoes of a kind in which the upper is secured in lasted relation to an insole by adhesion.

Objects of the present invention are to provide an improved method of making shoes and also a machine adapted for use in the practice of the method. In the attainment of one of its objects the invention provides a novel method of making shoes in which cement is used as an upper-securing medium, in the practice of which diiierent portions of the upper are fastened in lasted relation to a last and to an insole on the last by fastenings which are themselves adhesively secured to the upper and the insole to hold the upper in lasted position until the cement has set and are thereafter removed from the shoe.- The fastenings, as illustrated herein, comprise strips of adhesive material which are laid over the margin of the upper and against the bottom face of the insole in the lasting operation, the material being of such a character as to adhere quickly and firmly to the upper and the insole. In the illustrated manner of practicing the method the temporary fastenings are removed from the shoe. after the cement has set, during and as an incident to an upper-roughening operation whereby the overlaid margin of the upper is roughened to prepare it for the reception of an adhesive for attaching an outsole to the shoe. In another aspect, the invention provides a novel method of lasting, whereby adhesive fastenings are applied progressively to the shoe in the laying of the marinal portion of the upper over the insole.

For use in lasting shoes in the practice of the novel method there is provided, in accordance with one feature of the invention, a novel organization comprising means for pulling an upper over a last and means for laying the marginof the upper over an insole on the last and fastening it in lasted position by fastenings which are adhesively secured to the upper and the insole. As herein illustrated, there is a gripper for pulling the upper over the last and an overlaying member for laying the margin of the tensioned upper over the insole and for also pressing a fastening of adhesive material into position to adhere to the upper and the insole. In the construction shown, the overlaying member comprises a freely rotatable roll which is moved inwardly over the shoe bottom by a carrier and is arranged to engage the end of an adhesive tape and as it moves inwardly to feed a portion of the tape from a source of supply and lay it over the upper and against the insole, a tape-controlling member being pro vided on the carrier to cooperate with the overlaying roll to bend the adhesive tape around the roll so as to position the end of the tape beneath the roll.

As herein shown, the above-mentioned carrier is mounted for forward movement in a direction inclined toward the bottom of the shoe and, in order that the margin of the upper Will be pressed into firm adhering relation to the insole throughout the entire width of the margin, there is provided, in accordance with a further feature of the invention, means for imparting to the overlaying iember substantially at the beginning of the forward movement of the carrier a movement in a. different direction to carry it into position to press the margin of the upper initially against the outer edge portion of the bottom face of the insole, and for then controllingthe movement of the overlaying member inwardly of the shoe bottom in such manner as to cause it to move in a plane substantially parallel to the bottom surface of the last. Thereafter the overlaying member is moved upwardly away from the shoe bottom in a direction substantially at right angles to the direction of its inward movement. Thus, as herein illustrated, the movements of the overlaying and fastening-applying member are so controlled that as it moves inwardly over the shoe bottom it presses the margin of the upper for its entire width against the insole and lays a fastening from the edge of the shoe bottom inwardly over the margin of the upper and against the insole beyond the inner edge of the upper. It is to be understood, however, that with respect to the above-described movements of the overlaying member the invention is not limited to an organization in which an adhesive fastening is applied to the shoe by this member.

For severing the adhesive fastenings from their source of supply there is provided, in accordance with another feature of the invention, means operating in time relation to the movements of the overlaying and fastening-applying member for severing that portion of the adhesive material which has been laid over the margin of the upper and against the bottom face of the insole. As

- illustrated, a knife is provided which is mounted for movement in the above-mentioned carrier beneath the fastening-applying member. The knife is operated by a spring which is arranged to be tensioned by movement of the fasteningapplying member toward the work and which is released to render it operative after the member has compieted its movement inwardly over the shoe bottom and substantially at the time when the member begins its movement upwardly away from the shoe bottom. The fastenings are thus severed from their source of supply close to the bottom face of the insole after they have been pressed into position to adhere to the upper and the insole in the lasting operation.

The above and other features of the invention, including various novel details of construction and combinations of parts, and also the novel method aspects of the invention, will now be more particularly set forth by reference to the accompanying drawings and pointed out in the claims.

The machine illustrated herein is of the same general type as the machine fully shown and described in Letters Patent of the United States No. 1,796,451, granted March '17, 1931 on an application of George Goddu. Accordingly, it is only necessary to refer herein, for the most part, to

the construction and the mode of operation of the novel overlaying and fastening-applying mechanism of this invention.

It will be understood that the shoe upper materials 2S, hereinafter frequently referred to inclusively as the shoe upper and including, for example, the upper leather or and the lining b, and the insole are assembled on the last 2d and the upper pulled over in the usual manner prior to the side-lasting operation. Before performing the side-lasting operation by the use of the illustrated machine, the margins of the various layers of the shoe upper materials (with the exception of the outer face of the upper leather) from a point substantially at or somewhat to the rear of the heel breast line to substantially the tip line may be coated with an adhesive which may or may not also be applied to the margin of the insole. The shoe is then supported bottom upward in the hands of the operator and adjacent portions of the sides of the shoe presented successively to the lasting instrumentalities of the machine.

In each lasting position of the shoe the upper materials are pulled by a gripper 25 and are then laid inwardly over the insole 22. and pressed into position to adhere thereto and are fastened initiallv in lasted position by temporary non-memargin of the upper and to the bottom face of the insole in the lasting operation. The present invention contemplates allowing the fastenings to remain on the shoe bottom until the cement has set suiiiciently to retain the upper in lasted position and then removing them, although this procedure may be varied if an outsole is to be attached permanently to the upper by stitches, in which case the fastenings may remain in the shoe. In such a case also the use of adhesive between the upper materials .and the insole may be dispensed with.

To assist in determining the proper relation of the shoe to the lasting instrumentalities of the machine there is provided an edge gage 28 which is arranged to engage the side of the shoe at or near the edge of the insole and a sole rest 35 arranged to engage the shoe bottom at a considerable distance from the edge of the shoe bottom. The edge gage 2!) is pivotally mounted at v 32 on a bracket 3 which is adjustable along a guideway 35 formed in the head of the machine and is held in adjusted position by a cap screw 38.

The gripper 26 comprises a pair of jaws M] which, in the illustrated machine, are curved latlaying and fastening-applying mechanism of this invention. The means for operating the gripper is not shown or described herein since it is the same as similar means shown and described in the prior Letters Patent hereinbeforementioned. AS more fully described in that patent the gripper 26 is moved first downwardly toward the bottom surface of the shoe and then outwardly into position to grip the shoe upper materials, after which it is given a heightwise movement to tension the upper over the last and then a movement inwardly over the shoe bottom while maintaining its hold on the upper. As the gripper 26 completes its inward pulling movement the lasting margin of the upper adjacent to the gripper is laid over the margin of the insole and pressed into position to adhere thereto by means which is arranged also to lay a strip of adhesive material over the margin of the upper and against the bottom face of the insole to hold the upper in lasted position.

In order that the margin of the upper will be pressed into position to adhere firmly to the insole throughout the entire width of said margin the overlaying means is moved into position to press the margin of the upper against the outer edge portion of the bottom face of the insole substantially at the beginning of its overlaying movement and preferably this movement of the overlaying member into pressure-applying position is completed before the gripper releases its hold on the upper.

In the illustrated machine the means for laying the margin of the upper over the insole comprises a freely rotatable roll 52 mounted on a laterally extending pin i in a cap &6 secured to the lower end of a bracket 38. The bracket Q8 is secured to the forward end of a carrier or slide 59 which is mounted for movement in a forwardly and downwardly inclined guideway formed on a member 52. The member 52; is secured by screws M to a holder 56 which has a downwardly extending aces; 641: 3

portion fast on a. rock shaft. '60 mounted in the head 62 offthe machine.

a cam 64 which engages aroll 66 on the slide and =1. which.- is formed in one side of a'cam wheel 68 As previously pointed: out, the overlaying memher is moved into position to press the margin of the upper adjacent to the edge of the shoe bottom against the insole substantially at the beginning of its overlaying movement. For this purpose there is secured to the rock shaft 60 a lever I2 provided with a roll 14 engaged by a power cam I6 formed in one side of a cam wheel TI on the shaft Ill; The configuration of the cam 76 is such that as the slide 50 begins its forward movement the member 562 that supports the slide is swung .in a clockwise direction as viewed in Fig. 1 to impart to the overlaying member 42 a movement in a different direction to carry it into position to press the margin ofthe upper against the margin of the insole adjacent to its outer edge. As theslide 50 continues its forward movement the cam [6 acts to swing the member 56 about its pivot in a. counterclockwise direction to vary the direction of movement of the slide 56 in such manner as to cause the overlaying member 62 to be movedinwardly over the shoebottom in a plane substantially parallel to the bottom surface of the last to lay the margin of the upper over the insole. After the slide 58 has completed its forward movement, a further swinging movement in a counterclockwise direction is imparted to the member 56 to carry the overlaying member 42. upwardly away from the shoe bottom in a direction substantially at right angles to the direction of its inward movement, after which the slide 56 is retracted to return the member 42 to its initial position.

In the illustrated machine the overlaying member 42 serves also as a member for applying fastenings to the upper and the insole to hold the upper in lasted position. The fastenings as herein illustrated comprise strips of adhesive material or tape which are fed from a source of supply and: pressed into position to adhere to the margin of the upper and the bottom face of the insole as the overlaying member moves inwardly over the shoe bottom to press the margin'of the upper against the insole. As shown in Fig. 1, there is loosely mounted on a support or spindle 18 on the bracket 48 a roll 80 of adhesive tape, a portion of which extends downwardly over a guide roll 82 pivotally mounted in the bracket 48 above the overlaying member 42 and into engagement with the overlaying member. As shown, the end of the tape is engaged by a tape-positioning member 84 which is adjustable toward or from the overlaying member 42 in a downwardly and rearwardly extending guideway 85 formed in the bracket 48; a cap screw fisbeing provided for holding the member 84in adjusted position.

The tape-positioning I member I 84' is provided with an end 9i! which, as shown; is formed and arranged to cooperate with the overlaying member 42' to bend the end of the adhesive tape beneath the overlaying member and thus to hold. the end of the tape in position to be engagedlby the overlaying member and pressed against the margin of the upper as the overlaying member moves into position to press the margin of the upper against the outer edge of the shoe'bottom. It will be readily seen that as the overlaying member is moved downwardly into position to Theslide 50: is. moved along the guideway toward and from. the shoe by press the margin of the upper against the insole substantially at the beginning of its overlaying movement the end of the adhesive tape will be engaged by it and. pressed into position to adhere to the margin of the upper, and that as the overlaying member moves inwardly over the shoe bottom a portion of the tape will be fed from the roll 80 and laid over the margin of the upper by the movement of the member. In order that the tape will be adhesively secured also to the adjacent portion of the bottom face of the insole the cam 64 is so formed that a forward movement of sufiicient extent is imparted to the slide 50 to carry the overlaying member inwardly over the bottom face of the insole.

For holding the roll 80 of adhesive tape on its support there is provided a cover 92 which is pivotally mounted at 94 on the bracket 48 and is held in engagement with a finished surface 96 (Fig. 5) on the'braoket by means of a spring 98.

The cover 92 is provided with a handle I80 by means of which it may be swung about its pivot 94 to facilitate removal and replacement of the rolls of adhesive tape.

For severing from the rollof adhesive tape that portion of it which has been applied to the upper and the insole by the overlaying member there is provided means operating in time relation to the movements of the overlayingmember for cut ting the tape close to the bottom face of the insole substantially at the time when the overlaying member begins its movement upwardly away from the shoe bottom. As shown particularly in Fig. l the cap 35 is provided with a guideway )2 for a chopping knife 134 which is carried by a member i516 pivotally connected to the lower end of an arm H38 which at its upper end is pivoted on a stud i It, Fig. 5, carried by the slide 50. The knife Hit is held in adjusted position relatively to the member Hit by means of a cap screw IE2 and preferably is so adjusted, when the parts are in their idle positions, that its cutting edge extends beyond the axis of the pin 44- a distance slightly greater than the radius of the roll 42 plus the thickness of the adhesive tape. The arm I 68 is operated to impart tape cutting movement to the knife Hi4 by a torsion spring M4, Figs. 1 and 5, one end of which is connected to a member H5 which may be turned to adjust the tension of the spring and is held adjusted position by a pin I I8 arranged to enter any one of a series of holes I23 formed in a member I22 fast on the end of the stud To limit the drivingmovement of the arm I98 there is provided a fiber washer I24 which is adjustable by means of a screw 26 mounted in a split bracket 28 on the slide to, a screw its being provided for effecting relative movement of the two parts of the split bracket to-bind the screw I in ad.- justed position.

For swinging the arm I 53 against the resistance of the spring i I 3 to retract the knife m4 prepare.- tory to the tape-cutting operation there is pivoted at on the head of the machine a lever i3 3; Fig. l, on which is pivotally mounted at I a latch $38 for engaging the lower end of a plate MB on the lever IE8. A spring 952 connected at one end to the latch 38 and at its other end to a pin M4 on the lever I35 tends to hold the latch I36 in position to engage the plate I i-E. It will thus be evident that, when the slide receives its forward movement the arm 858 is held back by the latch 35, so that the knife 58% does not move forwardly with the slide as; The slide 59. carries an adjustable screw I46 which is arranged to engage and operate a finger hi8 projecting from the latch I38. The forward movement of the slide 55, however, does not carry the screw l lfi far enough to act on the finger I48 since it is necessary to allow time for the overlaying member to begin its upward movement after the slide 50 has arrived at the end of its forward movement. Release of the arm IDS is accordingly effected in response to a movement of the lever I34 such as to cause the screw I46 to act on the finger M8 to disengage the latch 538 from the plate I49. This movement is effected early in the upward movement of the overlaying member by a path cam I50 formed in one side of the cam wheel 68 on the shaft II! and engaging a roll-I54 on the lever I34. In the return of the parts to starting position the latch I38 is engaged by a stop shoulder I55 on the lever 934 to hold it in position to connect again with the plate Mil when the slide 56 arrives at the end of its retractive movement.

In the operation of the machine briefly summarized the operator presents the shoe in engagement with the edge gage 28 and with the sole rest 3!] in position for the gripperjaws 4i), when operated, to engage that portion of the upper upon which a lasting operation is to be performed and then starts the machine by depressing a starting treadle (not shown) with which the machine is provided. The gripper then grips the upper and pulls it heightwise of the -last and. inwardly over the insole. inwardly over the insole the gripper is positioned substantially as indicated in Fig. 2. While the gripper is thus holding the upper the overlaying member @2 is moved forwardly by the action of the cam 64 on the slide 50 and substantially at the beginning of its forward movement is swung downwardly by the rocking of the member 56 about the axis of the rock-shaft 60. As the overlaying member is swung downwardly it engages the end of the adhesive tape and presses it against the upper while also pressing the upper down upon the bottom face of the insole at the edge of the shoe bottom. The overlaying member is then moved inwardly in a plane substantially parallel to the bottom surface of the last to press the margin of the upper progressively against the bottom face of the insole in position to adhere thereto through the action of the cement, and as the overlaying member moves inwardly it feeds a length of tape from the roll 80 and applies it to the margin of the upper and to the adjacent portion of the insole to hold the upper in lasted position (Fig. 3). As the slide 50 moves forwardly the knife IE4 is retracted against the resistance of the spring IIA through the action of the latch I38 upon the arm I08.

After the slide 50 has completed its forward movement the cam I6 acts to swing the lever 12 and the member 56 in a counterclockwise direction as viewed in Fig. 1 about the axis of the shaft 66 to move the overlaying member upwardly away from the shoe bottom. In predetermined time relation to the upward movement of the overlaying member and preferably at or near the time when the overlaying member arrives in the position shown in Fig. 4 the arm I98 is released by the latch I38 to the action of the spring I It in response to movement of the lever i3 3, and the knife I04 is thereby rendered operative to sever the fastening I5 of adhesive material from its source of supply. After the temporary fastening has been severed from the roll of fastening material the slide 50 is retracted to its In pulling the upper starting position along with the other operating- .normal to the edge curvature of the insole and that they may overlap one another to some extent particularly along the ball portions, and in narrow shank shoes, along the shank portion without this affecting their holding power.

ter the side-lasting operation has been performed the ends of the shoe are lasted in the usual manner, after which the shoe is in condition for the attachment of its outsole. As previously pointed out, the present invention contemplates that if, for example, the outsole is to be fastened to the shoe by cement the temporary fastenings will preferably be removed from the shoe after the cement which has been applied to the margins of the shoe uppermaterials or to the margin of the insole or to both, has set sulliciently to retain the upper in lasted position. This may be done conveniently without loss of time to the operator in a subsequent operation on the shoe, for example when the overlasted margin of the upper is roughened to prepare it for the reception of adhesive for securing it to an outsole.

The overlasted margin of the upper is usually roughened by means of a roughening tool such as that indicated at I60 in Fig. '7 which is rotated in a direction for its shoe-engaging portion to move inwardly from the edge of the shoe bottom. A suitable tool, such as is customarily employed for the purpose, is disclosed and claimed in Letters Patent of the United States No. 1,989,078, Granted January 29, 1935, upon an application of Charles G. Brostrom. Roughening tools of the type disclosed in the above-mentioned application are each provided with a plurality of wire bristles which act to roughen the upper without tearing or otherwise damaging it, and as the shoe herein shown is moved progressively past the roughening tool to cause the tool to act from substantially the heel breast line forwardly to the toe end of the shoe the wire bristles engage and remove the strips I5 of adhesive material from the overlaid margin of the upper, the shoe being preferably moved relatively to the tool to remove also any portions of the strips adhering- 1.
