FASTENING-INSERTING MACHINE.

To all 10710722 it may concern Be it known that I, FRED N. LA CrmrnLLn, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Fasteningdnsertin r Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like partz-i in the several figures.

This invention relates to fastening inserting machines and particularly to machines designed to shape the work and to apply a fastening to secure the work in its shaped condition. While the invention may have various uses and ap JliratiOns, it has been applied with advantageous results to the production of shoe insoles and particularly to the production of an insole which consti tutes the subject-matter of a co-pending application Serial No. 256,4:94t, filed by me October 2, 1918.

The insole referred to is formed by first channeling an insole blank having a rounded, somewhat blunt end from which a V shaped portion may be cut to form a sharply pointed toe, and turning up the lip or combined lip and flap, produced by the channeling operation, to form the sewing rib. l hereafter, the central. portion of the end, of the toe is out out, preferable by a V shaped cut, and finally the sides of the out are closed together, thus abutting the ends of the rib and prodiiic'ing an insole with a sharply pointed toe in which the rib at all points is correctly disposed relatively to the sole edge.

It is an objectof the present invention to provide means which is adapted without sacrifice of other utility for shaping the notched toe of an insole, either by pressing or mold ing the toe into its final pointed form, and for applying a fastening to secure the toe permanently inits shaped condition.

In a preferred form of the invention the means for shaping the work will be mounted between the work support and the fastening inserting mechanism and a notable feature of the construction is found. in the arrangement by which relative movement of the work support and the inserting mecha- Specillcation of Letters Patent.

nism preliminary to the insertion of a fastei'nnp; controls the operation of the work shaping means. i

Other features of importance relate to the construction and arrangement of the shapmg members by which they self-adiustinglv accommodate themselves to the work and provide for the access of the inserting mechanism to the work while in the shaping; members.

Along with the shaping; of the end portion of the toe, it is desirable to compress or mold or otherwise give a more permanent set to the rib which is formed by the channeling and turning-up operations. Accordingly, important features of the sha 'iing means for the insole are found. in means for engaging the rib around the toe portion of the insole to compress the rib and to mold it if the leather be in temper. If a piece of fabric carrying cement or other adhesive be inserted to provide reinforcement for the rib, the fabric and rib will be molded to gether.

Preferably, the invention in its illustrative embodiment will comprise a fastening inserting mechanism so constructed and an ranged as to clamp the work securely during the insertion of fastenings and to insure that the fastenings will be properly set.

Other objects and features of construction will be apparent from the iollowing detailed descriptirui and. will. be poin'ttai out in the claims.

In the drawings one embodiment of the invention is shown to comprise a fastening inserting machine which is preferably of the type disclosed in the patent to Borden, No. 1,016,930, granted February 13, 1912, the said fastening inserting mechanism comprising the usual wire feed device 12, fastoning forming and driving devices including the fastening guiding nozzle 14, and means 16 for varying the size and shape of the fastening. For a complete description of the fastening inserting mechanism refer.- ence should be had to the said patent to Borden.

In the illustrative construction the work shaping means is shown to comprise a work support 18 mounted at the upper end of the slidable post 20 which is guided for movement in the bearings 22 of the frame 24. Carried by the frame 24 is a bracket 26 having at its forward end bearings 28 in which are slidably mounted posts 30 joined at their upper ends by across bar 82. Each post carries a collar 34 (Fig. 6) adjustably mounted thereon and held against the upper end of its respective bearing 28 preferably by means of a spring 36 which surrounds the lower end of the post and is engaged between the lower surface of bearing and a member 38 adjustable on the post and held in adjusted position by a lock nut 40. Carried by the cross bar 32, in the illustrative machine, is a shaping member 42, means being provided in the form of set screws 44 and 46 (Figs. 7 and 9) for adjusting said shaping member toward and from a co-operating shaping member 48. In the construction shown, this latter member is pivotally mounted in a slide 50 which is arranged for reciprocation in guideways on the under surface of the table or work support 18. Referring especially to Fi 7, it will be observed that the slide 50 is provided with two bars 52 which extend forwardly into the guideways in the table, each bar carrying a pin 54 (Fig. 6) to which is attached on each side the forward end of a spring 56 having its rear end attached to a pin 58 secured to the under surface of the table. These springs operate to hold the slide 50 yieldingly in its rearward position of rest. In order that the shaping member 48 may not be displaced laterally from operative position and yet may have suiiicient movement to permit it to be self-adjusting with respect to the work, the said member, in the illustrative construction, carries on its lower surface a pin 49 which slides along a slot 51 (Fig. 7) in the upper surface of the table or work support 18. Means are provided for moving the shaping member 48 toward its cooperating shaping member 42, the said means, in the illustrated machine, comprising a cam member 60 adjustably mounted on the upper rear end of the bracket 26 and fixed in place on said bracket by means comprising preferably a set screw 62 en-- gaged in a slot in said member 60. The forward end of the cam member 60 is provided with a cam surface 64 normally in contact with a cam surface 66 on therear end of the slide 50. lVhen the table .18 which carries the slide 50, is moved upwardly, the said slide is forced. forwardly by the co-operation of the cam surfaces 61. 66. Above the cam surface 66 is another cam surface 67 011 member 60 which cooperates also with the cam surface on the slide 50 for purposes which will be hereinafter described. At the end of a shaping operation the table 18 moves downwardly and as this movement progresses, the springs operate to return the slide 50 to its r ar most position and maintain the cam surfaces 64 and 66 constantly in contact. lVhile, in the illustrative machine, one of the shaping members is shown stationary and the other movable with respect thereto to perform the shaping operation, it is to be understood that the scope of this invention is such as to cover an arrangement in which both members are made movable to co-operate with each other in shaping operations or an arrangement reversed from that shown by making stationary the shaping member now shown movable and causing the co-operating shaping member to move with respect thereto. in the construction disclosed, the shaping member 48 is shown provided with a forked, SlllJSiitLlli-lttll) V-shaped forward portion designed to engage spaced portions of the toe of an insole to shape the same by a pressing or a pressing and molding action, the V-shaped portion of the shaping member having preferably overhanging portions 68 to engage over the upper surfaces 70 of the edge of the insole, the vertical surfaces 72 on the shaping member being designed to engage the outer side of the upstanding rib 74 of the insole while the vertical surfaces 76 on the V-shaped portion of the presser member engage the vertical edge 78 of the insole tip to press upon and close tightly together the forked portions 79 of the insole and thus shape the forepart or tip of the insole. At the apex of the V-shaped portion of the presser member 48 is an openin designed to receive the nozzle 14: bf the fastenin iiiserting mechanism, thus permitting insertion of a fastening like that shown at 82 while the work is held clamped by the shaping members.

The member 42 is constructed to fit into the toe portion of the insole inside of the upstanding ribs and is arranged to press the insole upon the work support to prevent buckling of the insole while it is being shaped by the co-operating shaping member- 48 and has the further function of shaping the upstanding ribs in conjunction with the flanges 68 on the member 48. In some cases the insoles are presented to the machine while in temper in which case there is. a certain amount of molding in conjunction with the pressing which moves the forked portions of the insole into abutting relation and compresses the upstanding ribs. In other cases it is desirable to insert a piece of reinforcing fabric carrying cement or other adhesive which is rendered tacky on the application of heat. In

accordance with this feature of the invention the member 42 will be provided with a. socket 84: (Fig. 9) for the reception of a. heating unit 86 designed to form part of an electrical circuit. With this arrangement the member 42 will not only press the reinforcin fabric 88 4;) into the toe por tion of the insole, but will cause it to adhere firmly and be molded to the shape of the insole with flange portions firmly adhering to the inner surfaces of the upstanding ribs.

Mounted in the head 90 of the fastening inserting mechanism is the driving shaft 92 having thereon the fast and loose pulleys 94 and 96 which are normally held inseparated relation but are adapted to be placed in operativeengagement by the wedge 98 connected by the rod 100 to the starting and stoppingtreadle 1102 pivoted to the base portion of the column 104. upon a pin or rod 106.

The lower portion of the work sup porting post 20 extends below the lower bearing 22 and contacts with treadle controlled means whereby the. work supporting post may be manually raised. In the present instance, this means comprises a lever 1.08 pivoted at 110 to a lug 112 extending from the bracket 24, the rear end portion of said lever being pivotally connected at 114 to a treadle rod 116 connected at 11.8 to a. treadle 120 the fulcrum of which is preferably established on the pin or rod 106. The free end portion of the lever 108 is provided. with an adj ustable device upon which the lower end of the work supporting post 20 rests. In the present instance this device comprises a pin 122 which may be adjustably secured to vary the lowermost position of the work supporting post 20. Preferably the post 20 is rendered extensible in length by means of a turn. buchis construction 124 so that the work sup porting table 18 may be raised without al fecting the operative connections of the work supporting post with the automatic power means for operating the same.

In the use of the construction thus far described, it will beaipparent that upon depression of the treadle 120 the work supporting post will be raised manually toward the fastening inserting mechanism, quickly bringing the insole on the work supporting table into contact with the member 42 so that the work is clamped yieldingly on the table as the member 42 is carried upwardly against the action of the springs 36. At the instant that the work sup iiorting table 18 is started upwardly, the shaping member 4:8 is moved forwardly by reason of the co-operation between the cam surfaces 64-. and 66 located respectively on the stationary cam member 60 and on the carrying slide 56 (Fig. 6), so that the shaping member 18 commences at once to shape the work which. has been placed on the table with the portion to be shaped positioned in the bifurcated portion of the shaping member. Very shortly after the initiation of the upward movement of the work support the member 42 engages the work to co-operate with the member 418 in shaping the insole and in compressing the upstanding ribs. Since the member 48 is pivoted for slight lateral swinging movement, there is automatic adjustment of said member with respect to the member 42 as the two members come into engagement with opposite sides of the upstanding ribs. Toward the end of the upward movement of the work supporting table 18, the cam surface 66 on the slide 50 leaves the cam surface 64. and enters into contact with the cam surface 67 of cam member 60, thus maintaining the shaping members in clamped relation, and it is at this time that the power means for lifting the work supporting table is thrown into opera tion through the depression of the treadle 102, the result being that the shaping members are clamped more firmly than before through the operation. of said cam surface 6? just at the time that the fastening is being inserted The operation of the shaping members throughout is controlled from the work support.

I In the illustrated construction the power means for operating the work support comprises wedge means yieldingly actuated from the means for operating the fastening insorting mechanism. As shown, the bracket 24 is provided with guideways 126, preferably one on each side of the bracket 2 1. in each of which is mounted for reciprocating movement a wedge 128. Each of the guideways 126 may be formed by separate upper and lower flanges 130 which thus provide a passage between them for a pin 132 secured to each wedge 128. Connected toeach pin 132 is a rocker arm 134 secured to a rock shaft 136 mounted in suitable bearings which may be conveniently formed in the bracket 24, sufiicient play or-lost motion being providedibetween the pins 132 and the connections to permit rectilinear movement of the wedges without binding of the parts. The rock shaft 134- has secured thereto an arm 138 whichmay be yieldingly connected to suitable means actuated from the driving shaft 92 to impart to said arm 138 andthrough itand associated elements, as described, to the'wedges 128, the desired movements, as will presently appear.

Secured-to the main driving shaft 92 isacam 140 having a cam path engaged by a- 'terposed betweensaid bearing and a collar 152 adjustably secured to the rod 148, the construction being such that as-the cam 140 is rotated by the-main driving shaft 92 the rod 148 will be reciprocated-to impartto the wedges 128 reciprocating movement in their respective guides, provided suchmovement of the Wedges is not effectively obstructed. Should the wedges meet an effective obstruction suflicient to preventsuch movement, the rod 148 will still be reciprocated but instead of moving thearm 134, on the downward movement of the rod the spring 150 will yield and'simply be compressed, thus ermitting the wedgesto remain quiescent.

y this constructionvit is insured that the work support will be fully raised to work clamping position and held there as the fastening inserting mechanism is-operated, provided its movement toward-such position has been manually started or initiated. This result issecured by providing the work sup porting post with projections which, when the work support is in lowered position, will be too low to beengaged by the inclined surfaces of th Wedges and consequently offer an efiective obstruction to wedge movement under the action of the automatic operating means describech In accordance with the construction shown the work supporting post 20 is provided at the sides thereof in front of the wedges 128 with pins 154 preferably carrying rollers 156 for engagingthe wedges 128 as the latter are moved forward by the automatic means described. WVhen the work support 'is in lowered position, as for instance, when: the treadle 120 is not depressedbythe:operative, the axes ofthe pins and rollers are slightly below the front edges of the wedge inclines and if at such times the starting and stopping treadle 102 be depressed to start'the machine, the actuating means for the wedges will be operated but the rollers and pins on the work support will prevent wedge movement and'the work supaort will remain in lowered position. bhould the operative have manually lifted the work support, then the axes of the pins and rollers will have been raised sufliciently to permit the wedges to engage beneath them and thus lift the work support to full work clamping position and lock it for the insertion of fastenings. For a. complete description of the automatic means for operating the work support, reference should be had to United States Patent No. 1,291,754, granted January 21, 1919, to Matthias Brock for improvements in worksupport controlling and operating mechanisms, which discloses and claims said automatic mechanism.

Among the advantages of the manually controlled and automatically controlled work support herein described are those which relate to the control of the work support during the shaping operation. The operative through manual control of the work support has control of the shaping men'ibcrs at the beginning of their co-operating shaping action upon the work and can inspect the work and retain control of the shaping mem bers practically up to tlietime of the insertion of the fastening into the work. By the operation of the automatic means for operating the work support the shaping members are power operated. at the termination of the shaping operation to 'give a greater shaping effect than could readily be obtained by means operated solely by footpower and to clamp the work firmly in shaped condition during the fastening setting operation. Furthermore, power operation of the work support through the wedge means described insures perfect setting of the fastening.
