MACHINE FOR INSERTING FASTENINGS Original Filed July 25, 1923 3 Sheets-Sheet 3 Patented Oct. 15, 1929 GEORGE GODDU, F WINCHESTER, MAElSAGH'Ut-EETTS, AE'JSIGNOR TO UIIIIDEID SHOE MACHINERY CORPORATION, OF PATE-RSON, NEW JERESEY, A CORPORATION OF NEW MACHINE FOR INSEBTIITG- FASTENINGS Original application fi1ed July 23, 1923, Serial No. 653,291. Divided and this application filed June 11,

This invention relates to machines for inserting fastenings, and is herein illustrated as embodied in a lasting machine of the progressive type including in its organization sdneans for forming and driving staples to fasten the upper of a shoe in lasted position, this application being a division of a copending application Serial No. 653,291, iiled on July 23, 1923. It is to be understood, however, that the invention is not limited to machines of the particular type herein shown.

A feature of the invention consists in a novel organization of means for fori'ning a staple in one location and for transferring it to a different location for driving. In the machine herein shown each staple is driven into the shoe in a direction inclined to the V61? tical, and the staple is formed in a location above the path of the driver and is transferred an downwardly into said path. An object thus in View in a machine of the type illustrated is to position the staple-forming means where it will aiford ample room for the operation of the gripper that pulls the upper over the last and for manipulation of the shoe in present ing different portions of the upper in position for lasting. The transfer of the staple, in the construction shown, is effected by a portion of the staple-forniing means, namely, an outside former which is moved forwardly with a staple-guiding nozzle from which the staple is thereafter driven, and which by that movement forms the staple over a stationary inside former. Conveniently theoutside former, as herein illustrated, is further utilized to guide the staple as it is moved forwardly by the driver in the driving operation, and to that end it is so constructed as to provide an unobstructed opening in the plane of the staple for the movement of the driver. As thus constructed, the outside former does not engage the head or crossbar of the staple, but only those portions of the staple wire that form the legs of the staple. In order that this outside former shall not have to operate in such close rela tion to the sides of the inside former as to form the cross-bar solely by drawing action on the staple wire, for example in making a substantially straight cross-bar, with conse- Serial No. 198,180.

quent danger of weakening the staple at the junction of each leg with the cross-bar, the invention further provides a member separate from the outside former to co-operate with the inside former in forming the cross bar, this member, as illustrated, being movahle with the outside former in the stapleforming operation but not in the transferring operation.

It is desirable that the staple-guiding nozzle. which moves with the outside former,

shall have sufficient range of movement to permit it to be retracted well away from the shoe at the time when the gripper begins its operation on the upper in lasting each portion of the shoe, and accordingly the construction shown is such that the outside former occupies initially a position at a substantial distance from the inside former. Preparatory to the forming of each staple the staple wire is fed into position between the formers, and the invention further provides novel means for guiding the wire an d for maintaining it in position to be operated upon, the con struction shown comprising a guide movable with the outside former as the latter approaches the inside former and having an elongated slot to permit it to move relatively to the wire while maintaining the wire in proper position.

The above and other features of the invention, including also novel means for guiding the staple in its transfer from forming position to driving position, novel means for operatin and controlling the driver, and various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims.

Fig. 5 is a View similar to Fig. 4 showing the parts as they appear when the wire is Figs. 6, 7 and 8 are sectional views of the "-inside and outside formers and associated which the invention is herein shown as embodied comprises a stationary shoe rest 20 which, in operating upon shoes of the welt type, is adapted to engage the rib of the insole and to serve as a clinching member for the staples, a gripper 22 which is operated to pull the upper heightwise of the last and then inwardly over the margin or feather of the insole, and an overlaying member 24 comprising .a staple-guidlng nozzle which is movedxin a direction inclined to the bottom face of the insole to. lay the margin of the upper over the feather and against the rib and to hold it while a staple is driven by a driver 26 to fasten the upper to the rib, the

v legs of the staple being clinched on the inner face of the rib by the member 20, as illustrated in Figs. 11 and 12. j The construction ofthe gripper and the means for operating it need not bedescribed in detail, since they are' fully described'in the copending application.

7 In order to provide ample room for manipulation of the shoe and for the'operation of the gripper, the staple-forming mechanism is so constructed and arranged as to form each staple in a location out of alinement with tlie'staple driver 26 and above the path of movement of the driver, and there is provided means for transferring the staple downwardly into alinement with the driver between the staple-forming and the driving operations.

For forming the staple there is provided an inside former 28 supported in a stationary bracket 30 secured to the frame of the ma-' chine, the former 28 having a cylindrical.

ing position to driving position, with the eX- ception of a portion of the' wire-cutting means, are carried by a slide 36'whieh also carries the staple-guiding nozzle 24, this slide being mounted for reciprocating movement in an inclined guideway 38 in the head of the machine. For reciprocating the slide 36 there is provided a lever 40 adjnstably fulcrumed on the frame at 42 and having at its upper end a roll (not shown) engaged by a path cam 44 formed in a cam wheel 46 on a cam shaft 48 which is operated by means described in the copending application. The lower end of the lever 40 is yieldingly connected to a link 50 which is pivotally connected at 52 to the slide 36.

The outside former comprises two plates 54 secured to a slide bar 56 which is mounted for upward and downward movement in the slide 36 for a purpose hereinafter describe l, the plates 54 being arranged to co-operate with the inside former 28 to form a staple in response to the forward movement of. the slide 36 whereby the staple nozzle 24 is carried into engagement with the shoe. Also carried by the slide 36 is a cutter 58 arranged to cooperate with a cutter 60 on the bl'zKliOJ 30 to cut the wire w in the forward movement of the slide 36. To position the wire in proper relation to the inside and outside formers there is provided a guide 62 which guides the wire across the end of the inside former 28 until its end engages an adjustable abutment 64 in the bracket 30, the guide 62 being fast on a portion of the staple nozzle 24. By reference to Fig. 6 it will be seen that initially the outside former 54 is positioned at a considerable distance from the inside former 28, thereby providing for an increased range of movement of the staple-guiding nozzle 24- toward the work, so that it may be positioned initially far enough from the shoe to avoid interference with the action of the gripper, and the guide 62, which moves with the outside former, has therein an elongated slot extending substantially from the inside former to the outside former to permit to move relatively to the wire while maintaining the wire in proper position until it is engaged by the outside former. The guide member 62 is divided so that portions of it are positioned at opposite sides of the inside former. As soon as the outside former arrives in position to engage the wire, the cutters 58 and 60 operate to sever a length of wire proper for the forming of the staple. as illustrated in Fig. 7, and by the continued movement of the parts the section of wire is bent about the inside former, as illustrated in Fig. 8.

It will be seen that the two plates 54 of the outside former are separated from each other to provide an unobstructed opening between "them in the plane of the staple, for a purpose hereinafter disclosed. The outside former thus does not engage that portion of the staple wire which forms the head or cross-bar of the staple, but only the portions which form the legs, and it is provided with grooves 66 to receive the wire and shape the legs against ano shoul the opposite sides of the inside former 28. These grooves are so formed relatively to the inside former as not to subject the wire to as great a strain as would be necessary it the drawing action of the formers thereon were alone depended upon to shape the crossbar of the staple, in order to avoid weakening the staple at the junction of each leg with the cross-bar. For shaping the cross-bar there is further provided a member 68 formed on the lower end of a plate 70 which is fixed on the front face of a casing 72 that forms a part of the housing for the slide bar 56. Tl'ie member 68 extends into the space between the outside former members 54, and moves with the outside former in the staple-forming; operation so as to engage the cross-bar of the staple and shape it upon the inside former at the end of the forward movement of the outside formel'. As herein illustrated, the member 68 and the co-operatin face of the in ide former 28 are so shaped as to form a substantially straight cross bar on the staple, although the invention is not limited to means for forming a cross-bar of that shape.

After the slide 36 has completed its tor ward movement and the staple has been formed as illustrated in Fig. Sythe staple is carried by the outside former downwardly into the path of movement of the staple driver 26. For guiding the staple in its transferring movement there is provided a guide member 74 which is moved 'l'oiuvardiy with the staple nozzle 24 and the wire guide 62 in the staple-forming operation until one edge thereof is in alinement with the crossbar forming face of the inside former 28. The guide member 'Mis shaped similarly to the inside former, and thus guides the cross-bar and the legs of the staple during; its transferring movement, the ot the stapie lyin in the grooves 66 of the outside former. In order to insure that the cross-bar of the fllC will not catch upon the upper edge ot the member 7 1, this member is beveled at upper end, as indicated at 66.

At the end of the downward movement of the outside former the staple is located below the lower end of the guide member 74; and in the path of the driver 26, the arrangement being such that the lower end of the outside former embraces a bed member 78 of the driver guideway. The stapie legs are thus eonlii in a spare betwi the bed member 0 outside for ier above the arc cs 66, and the driver is Q'uideu in th' s ace between the bed mem Si 78 and the lower end of the guide nie 'aher M and in the opening}; between the outsid;

ioriner plates 54;. The guideway thus provided tor the staple and the driver is in alinement with a guideway 82 in the staple nozzle 2 It will be understood that the t1 u ers-nip; movement of? the outside former is e: ted by movement of the slide bar 56. In order to position the outside former, at the opposite limits of its movement, in proper relation to the wire-guiding slot in the guide 62 and to the driver guideway respectively, there are provided adjustable stop screws 84% and 86 which are arranged to engage a lug 88 pro j ecting from the slide bar 56, the stop screws beingadjustably clamped in position and being adapted for use in setting up the ma chine and in compensating for any wear that may take place. The downward movement of the slide bar 56 is effected by a cam 90 (Fig. 2) on the cam shaft 48 through connections comprising a bell-crank lever 92 pivoted at 94 on the head of the machine and a link 96 which connects the bell-crank lever to a lug 98 011 the slide bar 56, the lever 92 being provided with a roll 100 for engagement with the cam. The lever 92 is yieldingly connected to the link 96 through a spring 102 which bears at one end on the lever and at the other end on a sleeve 19lthreaded in a lup- 106 on the upper end of the link 96. Extending through the spring 1.02 is a rod 108 which is pivotally connected at its upper end to the lever 92 and slidin rly mounted in the sleeve 104, this rod h aving fast on its lower end a collar 110 which engages the lower end of the sleeve to provide connection whereby upward movement is imparted to the slide bar 56 by the lever 92. This upward movement is yieldingly effected through a spring 112 (Fig. 1) which acts on the lever 92 to force the roll 100 toward the cam 90. lft will thus be seen that both the upward and downward movements oi the outside iormer are effected by yieldable means, so that the stop screws 84L and 86 may determine the limits of movement of the former.

F or operating the staple driver 26 there is provided a bell-crank lever 114 which is pivoted on an extension oi the slide 36 and has clamped in a down uirdly exteni'linrg arm thereof a bar 116 the lower end of which is swiveled in a bearing in a block 118 mounted for upward and downward sliding move ments in a driver bar 129 to which is secured the staple driver 26. The lever 11 i is operated to impart staple-driving movement to the driver 26 by a torsion spring 122. F or swinging the lever 11% against the resistance of the spring 122 to retract the staple driver, there is provided means for depressing a forwardly extending arm of the lever, comprising a link 124: which is pivotally connected at 126 to a slide 128, this slide being; connected to another slide 130 which is vertically reciprocated by a crank 132 on the front end of the shaft 48. At its lower end the link 124: carries a plate 13-1 positioned at the rear of a plate 136 mounted on the frontend of the forwardly extending arm of the lever 11 and the plate 134 is provided with a shoulder 168 which is arranged to engage the upper edge of the plate 136 to impart to the lever 11-l its driver-retracting movement. A

spring 140 tends to swing the link 124 forwardly and thus to hold the plate 134 against the plate 136. It will thus be seen that retractive movement of the staple driver is effected by downward movement of the link 7 124. In order to cause the driver to drive the staple there isprovided means for disengaging the shoulder 138 of the plate 134 from the upper edge of the plate 136, thereby releasing the lever 114 to the action of its spring 122. For this'purpose the link 124 carries a cam member-142 which is arranged to engage a stationary cam member 144 on an arm 146 whichis fast on the head of the machine.

For limiting movement of the lever 114, the slide 36 has thereon a projection 148 in which is adjustably threaded a plug 150 which has therein a fibre disk 152 in position to be enn gaged by a boss 154 on the lever 114.

,The means for feeding the staple wire may be of any suitable construction As herein illustrated, there are provided feed rolls 156 i and 158 to which the wire is fed from a reel (not shown), the roll 158 being yieldingly impressed. toward the roll- 156 by a spring 160. :For operating the feed rolls there is provided I pawl and ratchet mechanism'162, 164 operatedby a rocker arm'166 yieldingly connected by a spring 168, to aroek shaft 170. A rock 3 zi-izshaft 17 is operated bya cam 171 at the lower end of a vertical shaft 17 2 which is connected by a gearing 174to the shaft 48. Afterthe wire leaves the feed rolls 156,158 it passes through a guide tube 176 by which it is directed to a V Su i-guide block 178 fast on the bracket 30. From the block 178 the wire passes into the slot formed in the guide 62 and across the rear face of the inside former 28 until it engages the limiting stop 64. c

.i In theoperation of the machine, briefly summarized. the shoe is presented with the rib of the insole in engagement with the staple-clinching member in each locatlon where a lasting operation is to be performed,

if 4 and the upper is gripped and pulled by the gripper 22' in the manner described in the copending application. Before the upper is released by the gripper its margin is laid 1nwardly over the feather of the insole and against the rib by the action of the staple nozzle 24 which is advanced by a forward movement of the. slide 36-. By this forward movementof the slide 36 the outside former 54 and the cross-'bar-forming member 68 are carried forwardly toward the inside former 28, and after a movement of the slide corresponding to the distance between the outside former and the inside former the cutters 58 and 60 act on the staple wire previously fed intopositionin the guide 62 to out therefrom a section ofwire of properlength for a staple. By continued movement of the'slide 36 the outside former acts to bend the wire about the inside former and thereby to form the legs 65 of the staple, and at the end of such move ment the member 68 engages the cross-bar of the staple to shape it against the inside former. By this forward movement of the slide the guide member 74 is advanced until its rear edge is in alinment with the cross-barforming face of the inside former. After the slide 36 has arrived at the end of its forward movement, the outside former 54 is moved downwardly by the lever 92 to carry the staple away from the crossbar-forming member 68 and along the guide member 74 until it arrives in alinement with the staple driver 26. The outside former then remains at its lower limit of movement to guide the staple at the beginning of its driving movement. After the staple has arrived in alinement with the driver, which has been previously retracted by the action of the member 124, the driver-operating lever 114 is tripped and the driver is operated to drive the staple and to clinch its legs against the anvil member 20. Thereafter the parts are returned to their starting positions preparatory to the forming and the driving of another staple in the next location on the shoe where a. lasting operation is to be performed.
