. 13 Claims.

. This invention relates to an improved method of and a machine for inserting fastenings into work pieces, such as shoe parts, and is herein illustrated as applied to the attachment of shoe uppers to ribbed sole members after portions of the upper of each shoe have been worked into lasted relation to the `sole member. Ribbed sole members are, for example, used in the form of lipped insoles in the manufacture of welt shoes.

In the manufacture of welt shoes, particularly of the Goodyear type in which the margin of the upper is secured in lasted position tothe insole lip, it is common practice to employ fasten ings, such as two-legged staples, to secure the upper to the insole lip, each staple being inserted. straight through the upstanding margin of the upper and the insole lip and the end portions of the staple legs emerging from the rear side of the insole lip being iiared apart and clinched against the rear side` of the insole lip by an anvil or the like.

It is an object of the present invention to irnprove upon fastening inserting methods and machines of the type referred to, and particularly `to insure that the inserted fastenings have considerable holding power albeit they preferably are, in a sense, single-legged fastenings, and that the accuracy of their formation is consistent and thus their insertion uniform.

It is another object of the invention to provide an improved fastening inserting method and machine whereby a fastening which preferably and as illustrated comprises a straight piece of fastening material, such as wire, is inserted endvvise and caused to pierce the entire thickness of the work, the insertion being so controlled that the driven fastening resembles a staple the opposite ends of which are anchored within the work so as not to interfere with succeeding operations, such as the inseamsewing operation in the illustrated example of a Goodyear welt shoe.

In one important aspect the invention accordingly provides a novel and improved method of inserting through-and-through fastenings (i. e. fastenings which pierce the entire thickness of the work) according to which each fastening is driven straight through the work from one side thereof until the trailing end of the fastening is embedded in the work below the work surface at that side. The leading end portion of the fastening is caused to emerge from the opposite side of the work during the driving of the fastening, the leading end portion, however, being turned back into the work and caused to reemerge from l the side of entry thereof, where it is deflected a second time and reinserted in the work at the side of entry so as to anchor that end portion in the work and embed the extremity thereof bebeneath the work surface.

In another important aspect the invention provides a novel and improved fastening inserting machine adapted for use in the practice of the above-mentioned method and provided with a throat member adapted to engage one side of the Work and a fastening deflecting member or anvil adapted to engage the opposite side of the work. A driver movable in the throat member serves to insert each fastening endwise through the throat member into and through the work until the trailing end of the fastening is embedded or countersunk beneath the ing is embedded or countersunk beneath the surface of the work engaged by the throat member. The anvil serves to engage the leading end portion of the fastening when emerging from the side of the work engaged by the anvil and to turn it back into the work causing it to reemerge from the side of entry of the work. Moreover, the throat member is provided with a clinching cavity which receives the reemerging leading end portion of the fastening and turns it back into the surface of the work engaged by the throat member. Thus the fastening. inserted into the work has the form of a staple the opposite ends of which are securely anchored inside of the work where they can not form dangerous or annoying obstructions, and only portions of the thin smooth shank of the driven fastening are visible on 0pposite sides of the work.

While the invention is thus disclosed herein in its application to the attachment of shoe uppers to lipped sole members, it will be recognized that in a more general aspect the invention provides a novel method of and a machine for inserting fastenings not limited in utility to the fastening of uppers nor to shoe manufacture. In fact, the illustrated machine may be used to good advantage for the insertion into Work pieces of straight fastenings, not bent or clinched in any way, such as for the attachment of toplifts to heels by wire slugs, it being necessary in such a case merely to remove the anvil.

These and other features of the invention will now be described in detail with reference to the accompanying drawings and will be pointed out in the appended claims.

Fig. 13 is a plan View of a section through the throat member with a work piece presented thereto, illustrating the driving of the fastenings.

It has been stated that the present invention involves, inter alia, anovel and improved method of inserting fastenings into-a work piece. 1n the illustrated examplethe Work piece is a shoe comprising an upper U (Figs. 1, 10-13) on a last L,

the last carrying on its bottom a ribbed or lipped l rinsole I into lasted relation with which the upper `is worked and then secured in this relation by .fastenings inserted through the margin of the upper and the lip of the insole. The fastening `used in the practiceof the present invention is a single-legged fastening in the sense that it comprises a single straight piece of wire or simi- After the upper U has been tensioned on the last L and its margin worked into lasted relation to the feather portion and lip of the insole I. the fastening is inserted endwise straight through the margin of the upper and the lip, the trailing end of the fastening finally becoming embedded or countersunk in thesurface orside of the work whence it was driven (hereinafter referredto as the side .of entry) and the leading end portion of the fas- ,fastening is caused to penetrate again the entire thickness of the work (lip and margin of shoe upper) in a reverse direction and to reemerge at the side of entry of the work. The reemerging leading end portion ofthe fastening is engaged by another deflecting member or clinching .member which causes that portion of the fastening to be turned back into the side of entry at a point between the point of entry and the point of reemergence `so as not to interfere with the countersunk trailing end of the fastening and so as to form a staple-like driven fastening which resembles a closed `ring with the opposite ends overlapping and anchored Well within the work. Thus the ends can not interfere with or impair succeeding operations in the processing of the shoe, such as the inseam sewing operation.

The illustrated machine is particularly adapted for use in practicing the above-described method but, as previously pointed out, it is by no means limited -in its vutility to the insertion of fastenings into shoe parts of the aforementioned type or shoe parts in general.

General organization of the machine The principal operating instrumentalities of the machine and 4their actuating mechanisms are contained in or secured to a box-like frame 20 (Figs. 1 to 4) which is adapted to rest on a support (not shown). The principal work engaging loperating instrumentalities of the illus- 'trated machine are a stationary anvil 22 (Figs. 1, 3, 10 to 13), an upper tensioning gripper 24, and a wiper 26 through which the fastenings are inserted, by mechanism to be described, into the work, the latter being manually presented to the machine in a position in which the anvil 22 engages the rear faceor inner side of the lip of the insole I on the 'bottom of the last L over which the upper U is `to be tensioned by the gripper 2li. The anvil -22,fof course, is caused initially to engage and support that portion of the ins-ole lip where the fastening .inserting .operation is to begin, the .operation Abeing repeated and progressing along :the vlip first at one side and then at the other side of the insole while the shoe is held in the operators hands and is successively moved or fed `by him with relation to the machine to present` different portions of the shoe successively to the operating instrumentalities of themachine.

The actuating'mechanisms of the-various movable operating instrumentalities of the machine are driven from a single cam shaft 28 (Figs. 1 to 4) extending transversely of the machine and arranged for rotation in suitable bearings provided inthe frame 2li. :The cam shaft 28 is driven by connections (not shown) to a suitable source of power, the connections including an operator controlled clutch (not shown) which, when maintained engaged, will continue to rotate the cam shaftandthus cause the machine to run through an indefinite .number of cycles, one cycle corresponding to one complete revolution of the cam shaft.

The gripper mechanism For `tensioning the upper U of a shoe presented to the machine in the position illustrated in Fig. 1, heightwise of the last, the illustrated machine is provided with the previously mentioned gripper 24 comprising two jaws 30 and 32 (Figs. 1, 10, 11, 12) which lare rotatable about a common pivot pin 34 and `whichhave upward extensions `provided `with `slots .'35, 38 inclined with relation to eachother. A transverse pin 40 extends throughboth slots 3h, 38Jand is carried at opposite endsrby parallel links 42 (Figs. 1, 9) pivotally secured at their upper ends to parallel arms .244 mounted for free rotary movement. on a transverse rodor shaft46'fast at opposite ends :in the 'frame 20. As will be described, the pin40 is movable heightwise of the machine so as to open and close the gripper jaws. Upward movementof the pin 40 lin the slots `36, 38 closes vthe gripper 24. The heightwise movement of the pin 'Mis produced byrocking `the parallel arms M. Tothisend-ea-ch arm .544

ably mounted on the rod 46.

4has an upwardly and rearwardly extending projection 48, the two projections 48 being intereach rod 52 and is conned between the boss of the arm 54 at one end and nuts 58 on the rod at the other end. As will be noted, operation of both arms 54 in a clockwise direction, as Viewed in Fig. 1, will produce a yielding movement in the same direction of the parallel arms 44, with the result that the pin 40 will be elevated to close the gripper. Thus the gripper is closed by a yieldingly operating mechanism. The two arms 54 are interconnected by a web 60 (Fig. 9). The right hand arm 54 (as viewed from the front of `the machine) is part of a two-armed lever 62 (Fig. 1) rotatable about the rod 46 and carrying at its lower end a cam roll or cam follower 64 held against the periphery of a cam disk 66 on the shaft 28 by a torsion spring 68 (Figs. 4 and 9) coiled about a spacer 66 between the hub of the lever 62 and the bearing of the rod 46, one end of the spring 68 being in engagement with the lever 62 and the other end with a xed portion of the frame. Rotation of the cam disk -66 thus causes operation of the transverse pin 40 to open and close the gripper. However, this motion is utilized not only for opening and closing the gripper but for moving the gripper heightwise of the machine either to tension the upper after itvhas been seized by the gripper or. to move the gripper into a position in which it can seize the margin of the upper. As has been pointed out, in the lowermost position ofthe pin 40 the gripper jaws are open and, assuming that the gripper itself is positioned at the lower end of its heightwise travel, it is to be noted that the movement of the lever 62 by the cam disk 66 in a clockwise direction, as viewed in Fig. 1, will cause an upward movement of the transverse pin 40, with the result that the gripper jaws are closed upon the margin of the upper presented thereto, while the gripper remains in its lowermost position. It is only after the gripper jaws have been rmly closed upon the margin of the upper that the gripper begins its heightwise movement to tension the upper heightwise of the last. To accomplish this the upper extension of the gripper jaw 36 is pivoted by a pin 1| to an arm 10 (Figs. 1 and 9) ro-tat- The pin 'H is the main support of the entire gripper 24 which is adapted to move about the pin '|I in a direction transverse to the shoe presented to the machine.

. The arm 'l0 is connected by a link 'l2 (Fig. 1)

to a friction device or retarder I4 of a conventional type which functions to prevent an upward movement of the gripper jaws while they are being firmly closed upon the upper. On continued upward movement of the transverse pin i 40 after `the closing of the gripper `theresistance of the friction device 14 is overcome and the gripper is moved heightwise of the machine, moving the arm 'l0 at the same time in a clockwise direction (Fig. 1) about the rod 46. Ee-

versely, when the gripper is in its elevated position with the jaws closed, downward movement of the transverse pin 40 serves to open the gripper jaws while the gripper is maintained in its uppermost position due to the retarding action of the friction device 14, which action is over- .1.ome, only, after the` gripper jaws ,have been` 2 opened, by the continued downward movement of the transverse pin. As illustrated in Fig. 1 the cam disk 66 is provided near its high portion with a depression or dip 16 which reaches the cam roll 64 after the high portion has passed it and causes in the elevated and upper tensioning position of the gripper a slight opening of the jaws to permit slippage of the margin of the upper `when the latter is being worked into lasted relation to the insole.

The wiper head or throat member To wipe each portion of the upper U over the insole feather and against the upstandinglip of the insole I after that portion of the upper has been tensioned by the gripper and is held under tension, there is provided a wiper head (Figs. l, 3, 5) which also functions as a throat member or nozzle in that the fastenings are inserted into the work through that member. The wiper head 06 is of a substantially rectangular shape having a tapering front end and being arranged for reciprocating movement substantially in a horizontal path into and out of engagement with the shoe presented to the machine. The wiper head 80 comprises a main portion 82 (Figs. 5, 6) which is provided at its right hand side (as seen from the front of the machine) with a cover plate 84. The wiper head is supported for movement toward and from the work on a front link 86 (Figs. 1 and 2) and a parallel back link 88, the two links having the same effective length. The upper ends of the links are pivotally connected to the wiper head 86. The lower end of the front link 86 is mounted to rotate freely on a rod 90 secured in the machine frame and the lower end of the back link 86 is mounted to rotate freely on a rod 92 secured in the machine frame. Pivotal connection between the upper end of the front link 86 and the wiper head 80 is established in the following manner. Secured to the left hand side of the wiper head 80 is an outwardly and downwardly extending bracket 94 (Figs. 3 and 6) which carries a horizontal pin 96 extending through a slot 98 provided in the upper end of the front link 86. Thus a lost motion is provided between the link 86 and the wiper head for purposes to be described. To actuate the wiper head there is provided a bell crank lever |00 (Fig. 2) which acts yieldingly on the front link 86 to advance the wiper head 80 toward the work. One arm of the bell crank lever |00 carries a roll or cam follower |02 engaging a cam groove provided in one face of a cam disk |04. The just mentioned yielding operation of the link 86 by the bell crank lever |00 is accomplished in the following manner. There is provided in the front link 86 a socket |06 and a similar socket |08 is provided in the upwardly extending arm of the bell crank lever |00. The two sockets are axially alined and house a spring ||0 surrounding a headed bolt ||2 extending from the front side of the link 86 through both sockets and through to the rear side of the upwardly extending arm of the bell crank lever |00 where it carries lock nuts bearing against said arm. As will be noted from an inspection of Fig. 2, movement of the bell crank member |00 in a counterclockwise direction will cause a yielding movement of the link 86 in the same direction to advance the wiper head toward the work but movement of the bell crank member |00 in a clockwise direction will produce a positive movement of the link 86 in thesame direction for purposes to be de..

The wire feeding mechanism .As previously explained'the fastenings torbe inserted by the illustrated machine are formed "therein from a continuous strand of fastening 'materiaL such as wire, which is fed forwardly in the machine step by step and the'leading vend portion of which is severed to form a singlelegged straight fastening. The .strand of fasteningmaterial is preferably Wound up on la reel (not shown) which is conveniently mounted for rotation on the machine frame and from which the wire passes through suitable guides (not shown) into a wire feeding mechanism. The

wire feeding mechanism includes an inter-mittently rotated feed wheel |30 (Fig. 8) with which cooperates a pressure wheel I 32, the wire passing between the two wheels. The pressure Awheel is rotatably mounted in a supporting leverI-34 pivotally secured at |36 to a rearward extension '|38 of the main portion 82 Vof the Wiper head. kThe wheel |82 is urged toward the'feed wheel I and to this end there is provided a bolt |40 one end of which is in threaded engagement with a tapped hole provided in a shoulder portion of the rearward extension |38. The bolt |48 ex vtends through a hole provided in a tail piece '|42 of the supporting lever A|84 and carries a spring |44 which is compressedbetween the head -of the bolt and the tail piece, the spring thus tending to rotate the supporting lever |34 in a counterclockwise direction, as Viewed in Fig. 8,

. so as tourge the wheel |32 into engagement With the wire and to hold the wire against the feed Wheel |38.

Mechanism is provided for rendering the wire feeding mechanism inoperative and to this end there pivotally secured to the rearward extension i318 hand lever |46. The hub portion -of the hand lever is slabbed off at one side to per- -rnit the supporting lever |34 to be so rotated that the pressure wheel |32 is moved into operative position in engagement withthe wire. Rotation of the hand lever |46 causes the round part of thehub of that lever to engage a right hand extension of the supportinglever 4|34 and Yrotate this lever in a clockwise direction, as viewed-in Fig. 8, thus movin-g the pressure Wheel |32 away from the feed wheel |38 and `interrupting the operation of the wire feeding mechanism.

The feed wheel |30 is loosely rotatable on a vertical stub shaft |48 which is rotatably mounted in bearings provided in the rearward exten- 'sion |88. The stub shaft |48 is adapted t0 be rocked and to this end carries a pinion |50 secured to the lower end thereof. Loosely rotatable kon the stub shaft |48 and xedly secured to the 4feed wheel |30 is a ratchet wheel -|5-2 whichis 'adapted to be engaged by a lpawl |-54 -pivotally carried on an armf-I'56-clamped tothe-stub'shaft |48. The pawl |54 is biased byia Espring |58-to engage a tooth of the ratchet^|52 rso that upon movement of the arm |56 in a counterclockwise direction, as viewed in Fig. 8, the ratchet |.5I2 and the feed wheel |30 will berotated. On reverse movement of the arm |56 in clockwise direction, the pawl |54 is caused to ride idly back over the teeth of the ratchet wheel |52 so as-to engage, after the conclusion of this idle motion, another tooth of the ratchet wheel, preparatory to imparting another forward rotationto the ratchetwheel |52 and the feed wheel |30.

The amount of rotation impartedto the feed ywheel |30 determines the extent of the vwire feed and thus the length of the fastening to be formed `from the wire. This amount vis adjustable and to this end there is provided a pawl-like shield or ,guard |60 ladapted to mask a portion of the ratchet wheel |52. The shield |60 is pivotally secured at |62 to an arm |64 loosely rotatable on the stub shaft |48. The shield|60 is so arranged that it is adapted t0 mask that portion of theratchet which the pawl |54 would normally engage .at the conclusion of its idle backward motion. A pin |66 carried by the arm |64 has coiled about it a spring |68 -one end of which is inengagement with the pivot pin 62 and the other with the shield so as to hold the latter in engagement with the ratchet Wheel |52. As will be noted from an inspection of Fig. 8, the pawl |54, when vInoving backward on its idle stroke, is caused to r.ride up upon the shieldA |60, with the. result that part of its succeeding forward motion is idle .in the sense that it does not produce any motion fof Kthe ratchet |52 until the pawl |54 has moved out `of engagement with the shield .|16 pivotally secured at y|18 (Fig. 2) to the rearward extension |38 of the wiper head. The lower portion of the hand grip |16 is lengaged by -sa spring pressed plunger which serves to ,maintain the latch I'I4 in engagement with one of the `depressions |12 so as to hold the arm :|64 inits adjusted position. As the feed wheel J|36 Yis rotated the wire grippedthereagainstbythe pressure of the wheel |32 is advanced andis fed into isaftube |82 (fFigs. -5, 8) `which is clamped at |84 -toitherearward extension y|38 of thevwiper head.

The front end of this tube is inserted into a-bore provided in a wire intake |86 (Figs. 5, '7.) which ts in a slot in the cover plate 84 ,to which it iis `secured. The :wirerintake ,:has a .wire passage -|88 through which the wire is passed-into abarshaped guide member |90 seated flush in alongitudinal slot vin the back of Vthe cover Iplate 84.

linee-guide. fmember has on vits f exposedzface a longitudinally extending groove alongwhich the Wire is passed, the open sideoff the groove being covered by the main portion :82 ofthe wiper head.

Thus'the wire is supported all around during 'the entire course of .its travel into the .wire severing flocation.

As described above,.the wire feeding'meohanism to -befrocke'dfbyafrack bar |92 (Fig. l8) whichis 978 reciprocated lin a `slideway |94 provided vin the 9` above-mentioned shouldered portion of the` rearward extension |38 of the Wiper head. Movement of the rack bar |92 toward the right of" Fig. 8 causes rotation of the pinion |50 in a counterclockwise direction, as viewed in Fig. 8, and thus causes a wire feeding motion to be imparted to the feed wheel |30. The movement of the rack bar |92 ltoward the right of Fig. 8 takes place against the resistance of a spring |96 located in the slideway |94, one end of the spring engaging the end of the rack bar and the other end of the spring being backed by a screw |08 threaded into the open end of the slidewaylllll, The main purpose of the spring |96 is to return the rack bar |92 and mechanism associated therewith into their initial positions after a wire feeding motion has been imparted to the feed wheel |30. The movement of the rack bar |92 in either direction is limited in that a lateral pin 200 (Fig. 2) se'- cured to the rack bar extends through a slot 202 provided in the outer wall of the slideway |94.

The forward end of the rack bar is pivotally con` nected by a double link 204 to a two-armed lever 206 rotatably secured by a fulcrum stud 208 to the wiper head. The lever 206 carries at its lower end a cam roll or cam follower 2|0 which is held in engagement with a cam 2 2 secured to the cam shaft 28.

`The wire severing and fastening transferring mechanism As has been stated, the leading end portion of the wire, each time the wire has been advanced in the machine, is cut off to form a fastening which, then, is inserted endwise into the work. To this end there is mounted in a circular recess 2 |4 (Fig. 6) provided in the front end portion of the Wiper head 80 a rotatable wire receiving roll 2|6 provide-d on its inner surface with a diagonally extending groove adapted to receive the leading end portion of the wire when the wire is being advanced in the machine. This groove is covered or bridged over by a disk or roll 2|8 of the same diameter as the roll 2|6 which it abuts, the disk 2 I8 being located in a circular recess provided in the cover 84. The disk 2|8 is secured to the roll 2|6 by screws or the like. The roll 2|6 and disk 2|8 are adapted to be rotated between two end positions, namely a wire receiving position, in which the groove in the roll 2 I6 is alined with the groove of the wire guiding member |90, the lower end of which terminates in close proximity to the periphery of the roll 2|6, and a fastening driving position or fastening presenting position in which the groove in the roll 2|6 is alined with the path of movement of a fastening inserting driver. To rotate the roll 2|6 it is provided with a laterally extending stem 220 (Figs. 3 and 6) to which is secured an arm 222. Thearm extends upwardly in a rearwardly inclined direction and its upper end is pivotally connected by a link 224 to a horizontal rod 226 of substantial length. Therear portion of the rod 226 carries two collars 228 and 230 between which the rod extends through a bushing 232. `Springs, 234 and 236 are carried on the rod 226 and are located between the bushing 232 and the collars 228 and 230 respectively. The bushing 232 is pivotally secured to the upperend of a lever 238 freely rotatable on the rod 92 and integral with a lever 240 carrying on its extremity a cam roll 242 which isin engagement with a cam groove provided in one side of the cam disk |04. Rotation of the levers 238, 240 by the cam groove in one direction or the other thus causes the wire receivingroll 2 6 to be rotated between the above- 10 described two predetermined positions. To limit and adjust the movement of the horizontal rod 226 in either direction so as to determine accurately the two positions of the roll 2|6, there is secured in a socket 246 (Fig. 4) provided in the rearward extension |38 of the wiper head a pin 248 (Fig. 3) on which is mounted a split sleeve 250 adapte-d to rotated slightly about the pin 24S. The two ends of the split sleeve have oppositely extending internal threads which are engaged by screws 252, 254. The screws are bored centrally to permit the passage therethrough of the rod 226 which also passes through the sleeve 250. The rod has fixed to it collars 256, 258 which, on movement of the rod in one direction or the other, are caused to abut against the heads of the screws 252, 254 to limit movement of the rod 226. The screws are adjustable and they are held in adjusted position by binding screws 260 engaging the split sleeve 250 and binding the screws 252, 254 against the threaded portions of the sleeve which they engage. Continued operation of the levers 238, 240 after one of the collars 256, 258 has engaged one of the screws 252, 254 is made possible owing to the arrangement of theI springs 234, 236 which, in this case, will be compressed and thus serve the further purpose of holding the wire receiving roll 2|6 in either one 4of its two predetermined positions by spring pressure so that the roll may not be jarred out of alinement with the wire guiding passage or the path of movement of the driver by any vibration of the machine. When the roll 2|6 is rotated out of its wire receiving position, the length of wire extending therein is severed from the wire strand due to the shearing action between the roll and the wire guiding member |90.

The fastening driving mechanism For inserting fastenings into the work presented to the machine there is provided a reciproeating driver 262 (Figs. 5 and 6) which, in the illustrated example, is extremely thin and of the same gage as the wire from which the fastenings '1 are formed. The driver is movable in and with relation to the wiper head and, as will be described, it is guided and covered all around and over its entire length during the entire course of its travel. The :driver 262 is movable in a barshaped guiding member 264 of rectangular cross section which is seated ush in a longitudinal recess provided in the back facev or inside face of the cover 64. The guiding member 264 has extending along the exposed face thereof a groove which serves as the driver passage and which is covered or bridged over, as will be presently described. The driver 262 is connected to a driver bar 266 which is reciprocated in a longitudinal recess provided in the main portion 82 of the wiper head. To hold the guiding member 264 in place there is provided a stop pin 268 (Fig. 6) driven into the cove-r 84 an-d abutting the rear end of the guiding member 264 the front end of which is positioned in close proximity to the roll 2|6. The driver 262 is secured to the driver bar 266 as follows. The rear end of the driver has a lateral fm 210 which extends into a slot provided in one end of a pin 212 carried by the driver bar 266. The rear end of the driver 262 is engaged by a hardened .pin 214 also carried by the driver bar 266 and positioned in tangential relation to the pin 212. The pin 214 is provided with a ridge which extends into the groove of the guiding member 264 and engages the rear end of the driver. As illus- ,'.trated in Figs. 2 and 6, there is pivotally connected to the rear end of the driver'barZa link 218 which in turn is connected to a driver actuating lever 218 arranged to swing abouta fixed rod 288 and adapted to be rotated by a torsion spring 282 coiled about the. hub ofthe lever 218, one end of the spring engaging a pin 284 on the actuating lever 218 andV the other end engagingVV a pin 288:

carried by the aboveedescribed link 88 supporting' the wiper head 88. The actuating lever 218V is adapted to be held in a cocked position,.with the torsion spring 2821oaded, by the engagement of ai locking pin 288`provided'on the lever 218 with a latch itifpivotally secured to the link 88' and having a depending arm 282 the lower end of which is connected by a link 29d to an arm 298 mounted for freeY rotation about the rod 28|] and provided with an elongated hub 288 to the other end of which is secured av similar-arm 382 (Fig- 1) car-- rying a roll 388 adapted to be engaged by the high portion of afcam 388 on the cam shaft 28. Asl will be noted, the just described cam operated mechanism is adapted tov release the actuating lever 218 to the force of the loaded spring 282 by tripping the Ylatch 298. The fulcrum pin of the latch 298 has coiled about it a torsion spring 388 "I the above-described bell crank lever |80, which l servesv to actuate the wiper head, by a link 3|0' the left hand end of which (Fig. 2) is pivotally secured to the upwardly extending arm of the bell crank lever |80 and the right hand end of which is provided with a slot SI2 which is engaged by a pin 313 carried by the driver" actuating lever 218. When the wiper head'88 is advanced by the coun'- terclockwise rotation (Fig. 2) of the bell crank lever 188 and the frontlink 86, the pin 8.6 carried bythe wiper head 88 is located at the rear end 'f of the slot 89 (Fig. 3) provided at the uppery end of the link 88 so that the wiper head 88' is pulled forwardly by the link 88, the link 88 swinging freely aboutY its rod Y92; In view ofthe link connection 368 between the bell crank lever Illlland thedriver actuating lever 218 and, furthermore, dueW to the fact that, at that time, the pin H3 is located at the rear end of the slot 312, the driver actuating lever 218 is advanced with the wiper head, with the result that the wiper head 80 and the driver 222 are moved as a unit towardV the work. It is to be noted that this advance of the driver and its actuating lever 218Y takes place while the actuating lever 212` is held cocked by the latch 298 which, due to the Yfact that it is carried by the link 88, is advanced concomitantly with the lever 218. After the wiper head 88 has moved into engagement with the work and has wiped the upper into lasted relation to the insole, the high portion of the carngdtbecomes active to trip the latch 288 so as to release the actuating lever 218 to the loaded spring 282 which is of considerable strength. This results in the operation of the driver. which is moved forwardly in the guide member 2811 and through the wire severing roll 2l8 while theY latter is in its fastening inserting position soV as to insert the fastening contained in the roll into the work; This movement of the driver, of course, takes place with relation to the wiper headwvhichfis held stationary and in engagement withv thework. Thefrelative" movement between the driver andzthefwiper headaafter' the latter has reached its operative position,.is possible due to the provisi'onlofV theslot 312: in theA link tit, enabling the driver` actuating lever 2:18' to be propelled' forwardly by the spring 282 while the wiper actuating mechanism to which it'I is connected remains stationary. Reversely, when the bell crank lever' |88 is rotated'by its cam |84 in' a clockwise direction, as viewed in, Fig. 2, the wiper head 88. is'not' directly affected by thismotion of the bell crank` lever |80, this being duei to the lost motion provided betweenthe front' link 85 and the wiperl head by the slot 98. However, since theV lost motionprovided between the bell crank lever |88 and the driver actuating lever 218 by the slot 3'l2'hasbeen taken up as a result of the driver operating forward movement yof the lever 218-with relation to the linkY 3l 8T causing the pin 3l3 to move to the forward end of the slot 312, the driver actuating lever 218i is immediately moved backward on initiation ofthe above-mentioned clockwise rotation ofthe bellcrank lever 188. This backward movement of the lever 218 serves the purpose ofV loading the torsion-spring 282 and cooking the lever 218'. Sinceone endof the spring 282 bears against the rear link88supporting the wiper head 80 the rear link 88 also is swung rearwardly thereby retracting the, wiper head 88. As described, the. rearward movement of the link 88 and the wiper head is terminated by the engagement of thescrewr |20 with the abutment i i8 thus enabling the driverA actuating lever 21'8'to move fully into its cocked position, it being understood that the slot98- is of suiicientlength to permit such movement of the lever 218, the bell crank lever |88 andthe front link 88.

The operative movement of the driver is lim-` ited andthe extent of vthis movement is adjustable by the` provision of a rod 3M' (Figs. 1 and 2) pivotally secured to the driver actuating lever 218i and extending through an. aperture 318 provided in the link 88. The rod 3 Ill carries at its rear end a bumper 3.18 adjustably secured on the rod. The

bumper, on operation of the driver, is adaptedto nstrike against' the rear face of the link 88 thus terminating the operative movement of the As already mentioned, the driver on its operative stroke moves through the groove provided in the wire receiving and severing roll 21'6, the roll, of course, first having been rotated into the fas- Y tening inserting position in' which its groove is in alinement withthe driver passage of the guiding member 284. Between the roll ZIB and the outer end of the wiper head 88 is provided a nozzle piece 328 (Fig. 6) having a projection or stem 322 extending into a hole provided in the main portion 82 of the wiper head. The nozzle piece 328l is grooved similar to the 'wire receiving roll 2G t and its groove is in alinement with the driver passage andthe groove in the roll ZIB when the roll is located in its fastening inserting position. The nozzle piece 328 is engaged by a cover piece 324 which also has a' projection or stem 328 engaged in a hole provided in the cover plate 84; Moreover, the visible front end of the cover piece 324 has a clenching cavity' 328 which servesv to engage the leading end portion of the fastening when it reemergesfrom the sideof entry of the work. and 'to curve thatportionto cause it tore'- 13 enter the work, as has been described. The clenching cavity 328 is so shaped that the extremity of the leading end portion of the fastening is caused to reenter the side of entry of the work at ya point located between the point of entry and the point of emergence.

`It will be noted that as a result of the provision of the longitudinal recess in the main portion 82 of the wiper head 80 to accommodate the driver bar 266, the driver can not be covered by the main portion 82 over the entire extent of its travel in the groove provided in the guide member 264. However, to insure nevertheless that the thin driver is fully supported in any position of its reciprocation, there is provided a movable guard member 335 (Figs. 5, 6 and 12) which has somewhat the shape of a long hatchet and is located in a recess provided in the main portion 82 of the wiper head. The guard member 338 has a curved face 33! located in close proximity to the complementary curved front face 333 of the driver bar 266 and is adapted to cover the driver between the driver bar and the roll 2I6. The guard member 336 is pivotally secured by a pin 332 to the wiper head and has extending downwardly and rearwardly from it an integral arm 334 which is connected by a link 336 (Fig. 2) to the rear end of the driver bar 266. As a result, the guard member 336 is caused to swing upwardly on advance of the driver bar 266 to make room for the driver bar while continuing to cover the driver in the diminishing space between the driver bar and the roll 2|6. Reversely the guard member is caused to swing downwardly on retraction of the driver bar 266 to insure complete coverage of the driver. However, it will be noted, particularly from an inspection of Fig. 5, that movement of the guard member about its pivot pin 332 causes diierent portions of that member to become active to cover the driver and these different portions are located different distances from the center of the pivot pin 332. Consequently, the different covering portions of the guard member 336 move at different speeds about the pivot pin 332 during the rotary motion of the guard member 330. To oiset this factor, which is apt to result in exposing the driver at some time or other during its travel, the above-described arm 334and link 336 act as a toggle which upon advance of the driver bar 266 is moved toward a zero position, with the result that movement of the guard member is decelerated, slowing down the covering portions the distance between which and the pin 332 increases at that time. Reversely, on rearward movement of the driver bar 266, the movement of the guard member is accelerated.

The anvil The previously mentioned anvil 22 has a stem 346 (Fig. 1) which is mounted in a bracket 342 provided on the machine frame 2|] at the front of the machine. The stem 340 is adjustable in the bracket 342 heightwise and widthwise of the machine and is held in adjusted position by clamping screws 344, 346, a set screw 348 serving the purpose of making i-lne adjustments for changing the heightwise position of the anvil. As previously pointed out the anvil engages the inner side or rear face oi' the insole lip and thus it supports the lip against the thrust of the wiper head `86 as well as the thrust of the driver and the fastening inserted by it. Moreover, the shoe is guided bythe contact of the insole lip with the anvil. The anvil, of course, serves the additional 14 purpose, already described, of deflecting the leading end portion of the fastening after it has fully pierced the margin of the upper and the insole lip to deflect that portion of the fastening and turn it back into the work.

The gripper throw-out mechanism To adapt the illustrated machine to insert fastenings without utilizing the gripper mechanism either to process certain portions of the work piece where the gripper operation is unnecessary or undesired, or to insert fastenings into other types of work where no gripper operation at all is required, mechanism is provided to render the gripper mechanism inoperative and maintain it in an inoperative out-of-the-way position. To this end the gripper jaw 32 is provided at its upper portion with a toothed segment 350 (Fig. l) which is adapted to be engaged by a locking pawl 352 pivoted to a boss 354 provided on the other gripper jaw 30. A torsion spring 355, mounted on the hub of the pawl 352 and having one end engaging the pawl and the other the boss 354, tends to depress the pawl 352 into locking engagement with the segment 356. The pawl has an upwardly extending arm 356 the upper end of which is pivctally connected to a link 3'58 arranged for lengthwise reciprocation and carrying at its rear end a pin 366 (Figs. 1 and 9) the opposite ends of which engage slideways provided in a forked tail piece 362 of the arm 1I).` Sliding movement of the link 358 toward the left of Fig. 1 permits the spring 355 to move the pawl 352 into locking engagement with the segment 350 and sliding movement of the link 358 toward the right of Fig. 1 lifts the pawl 352 out of engagement with the segment 350. The link 358 is connected at its rear end .by the pin 360 to a latch 364 of substantial length. The rear end `of the latch 364 is of considerable width, and in order to maintain the pawl 352 in its elevated inoperative position and thus to maintainthe gripper operative, the hooked rear end of the latch 364 is normally engaged by a pawl 366 freely rotatable on a transverse shaft 368 rotatably mounted in the machine frame. The pawl 366 is biased by a torsion spring 310 which tends to move the pawl in a clockwise direction, as viewed in Fig. 1, into locking engagement with the latch 364. This movement is limited by a xed stop pin 312 engaging a slot provided in a depending portion of the pawl 366. To render the gripper mechanism inoperative the latch 364 is elevated out of engagement `with the pawl 366 and this is eiiected by a plate (not shown) secured to the shaft 368 `and underlying a portion of the rear end of the latch 364. Secured to the shaft 368 and spaced from the just mentioned plate is a similar plate 316 which overlies the end of a treadle rod 318 upward movement of which, when permitted, causes the plate to be raised with the result that the latch 364 is freed. As soon as the latch 364 is disengaged from the pawl 366 the spring 355 becomes active to slide the link 356 toward the left of Fig. 1 and to depress the pawl 352 into locking engagement with the segment 35i) so as to prevent the gripper from closing. Mechanism is provided to prevent the upward movement of the treadle rod 318 even though the rod may be vstressed in that direction until a predetermined point in the cycle of gripper operation has been reached. namely when the gripper is substantially in its down position and its jaws are open. In this position of the gripper the Icam roll 64 is near the low portion of the cam disk isf 6'6. Thepurpose of thisarrangement is to insure:

that the' gripper'is open when it is being rendered inoperative, the gripper jaws being locked in their open position,v whereupon the gripper is elevated into its ir'loperativel position and held in that position, as will be described. To accomplish this the treadle rod 318 has secured to it a collar 366 'the'right side of which is provided with a shoulder, as illustrated in Fig. 1. With the collarltil" cooperate two pawls, namely a left-hand pawl Stil, adapted to engage beneath the collar 380 andlhold it and thus the treadle rod 318 in an elevated position. A right-hand pawl 384 normally engages the shoulder portion of the collar so as to'prevent upward movement of the collar and the treadle rod 313. The two pawls 382, 3M are biased by springs (not shown) toward; the collar 38d and are pivotally secured to a bracket 386" mounted in the machine frame. To operate the pawls there is provided a pin 388 extendinglaterally from a link 39B the front end of which is pivotally .secured to the gripper operating cam lever t2 and the rear end of which is slotted, the slot being engaged by a pin 392 eX- t'endin'g laterally from the bracket 38B, this to permit lengthwise reciprocation of the link 39|] upon rocking movement of the cam lever (i2. As will be described, the pin 388, when being reciprocated by the link 390, is adapted to release either pawl 382 or 384 from `engagement with the collar 380. For the purpose of maintaining the gripper mechanism locked-out there is securedon the treadle rod 3l8'a collar 384 which is adapted on upward movement of the treadle rod to engage a latch 395 pivotally secured at its right-hand end (Fig. l) to the bracket 3816 and normally maintained in a low position against a stop pin t9? by aspring 398; The latch 39d when raised by the collar 334 is adapted to engage behind a shoulder 4M) provided on the link 390 when'that link'is in its forward position in which the gripper is elevated, this preventing the link from returning. Thus the gripper is locked in its elevated inoperative position.

In the position of the machine parts illus-trated inA Fig. 1, the gripper mechanism is operative and the gripper throw-out mechanism is inoperative with the treadle rod 318 down and its upward movement prevented by the engagement of the pawl 3313 with the collar 380. nowV that upward pressure is applied to the treadle rod 318. Nothing happens until the low portion of the cam 66 is opposite the cam follower lill and the link'390 has been moved rearwardly by the cam lever 62, causing the pin 388 t'oengage the pawl 384 and knock it off the collar SBU. Now the treadle rod 318 is free to move up. As will be noted, the upward movement of the treaclle rod is Ithus possible only when the low portion of the cam 65 is opposite the roll t4 or, in other' words, when the gripper is down and open. The upward movement of the treadle rod 311BY accomplishes two things. First, the plate 315i is' elevated, freeing the latch 36d to enable the torsion springv 355 to depress the pawl 352 into locking engagement with. the toothed segment 354i. Accordingly, the gripper cannot be closed. The other function exercised by the treadle rod is, as already described, the elevation of the latch 3% into aposition in which, upon forward movement of the link 390, as the cam roll B4 approaches the high portion of the cam 36, it can snap behind the shoulder 400 and thus hold the e'am' lever 52 locked out in av position similar to that shown in Fig. l. It should be noted that Let it be assumed f this outward movement of' the link 39E! by the'. corresponding movement of: the cam lever 52 inr a clockwise direction, as-viewed inFig. l, causes elevation of the gripper into its inoperative position with the gripper jaws open, the gripper being` then maintained in that position by reason ol?A the locking of the link 380l against rearward movement by the latch 396.-

enabling the pawl 382 to engage beneath the collar 38@ to hold the treadle rod Sl' up. Thus, a slight forward movement of the link 390 occurs even while the gripper mechanism is locked out. when the cam roll iilpassesover the highestpor-l tion of the cam @5 with the result that the pawl.

382 is moved out of engagement with the collar 38S once during each cycle, namely when the highest point of the cam 66 is opposite the cam roll (it. Accordingly, the treadle rod 318 canbel loweredagain only at that time. When it is desired to throw the gripper mechanism into The pawl 382 becomes auto,A matically unlocked when the cam roll 64 passes over the highest portion'of the cam Q6, causingthe abovenmentionedfslight forwardv movement` of the link 3&0'- and the pawl releasingl pin 338.-

As the treadle rod 311i goes down the collar 394- also is lowered, permitting the spring 398 to pull the latch 396 out of engagement with the shoulder dell, thus enabling the link 390 again to move rearwardly in the machine and accordingly permitting the gripper to descendandto be operated in the normal way.. Of course, the lowering of` the treadle rod 313 also causes the plate 31Bfto be lowered, with the result that the latch 364 is lowered. To unlock the gripper jaw 32 by raisingr the locking pawl352 there is secured on the rear- Ward extension l38 of the wiper head a catch 402` (Figs. 1 and 2) which,v during the rearward move-'- ment of the wiper head, engages the hookedend of the latch 364 and pulls the latch rearwardly into locking engagement-with thepawl, there-- by sliding the link .'irearwardlyl in the machine and elevating the pawl 352 against the pressure of its spring 355.

The Machine vOperation In the operation of the illustrated machine, a work piece comprising an upper U assembled on A a last L carrying a lipped insole Ion its bottom' is presented to the machine with the last bottom' up and the inner side of the insole lip resting against the anvil 22 at a-location where the fastening inserting operation is'fto begin. The mar'-y gin of the upper is placed between the open jaws of the gripper 24 wh'i'ch'is' in its lowermost position. The clutch controlling the rotation of the cam shaft 28 is thenenga'gedto initiate the op-v eration of the machine. The different cams controlling the operations of the different actuating mechanisms of the machine are so designed that the sequence of the operations in one cycle of' the machine is as follows. The wire receiving and severing roll 2l6 is nrst rotated into its wire receiving position while the wiper head is still in its rearward inoperative position and the gripper is down and' open. Thereupon the wire feeding mechanism is actuatedto feed a length of wire into the roll 2'l6 which then is rotated into its fastening inserting position, thereby severing the fedi-in' length of wire from the strand to form a fastening and-to 'locate"thefastening-in However, ,the linky 35i? is not locked inits frontmost position, thus'- 17 the path of the operative movement of the driver. Then the gripper is closed upon the upper and elevated to tension the upper heightwise of the last, as illustrated in Figs. and 11. Simultaneously with the initiation of the gripper operation, the wiper head B0 begins its forward movement into engagement with the tensioned margin of the upper. The gripper jaws are slightly opened, due to the dip 'IS in the gripper actuating cam 66 at that point, to permit slippage of the upper between the gripper jaws as the gripper remains in its elevated position, thus to enable the wiper head 8l) to wipe the margin of the upper inwardly over the insole into firm engagement with the feather portion of the insole and the lip and well into the crease formed by the feather and the lip, without tearing the upper. Moreover, due to the fact that the gripper 24 is suspended on the pivot pin 1I and thus can swing transversely of the shoe presented to the machine, it can participate, while in its elevated upper tensioning position, in the inward wiping movement of the wiper head, thus further insuring against any tearing of the upper. The wiper head, having completed its wiping operation, is held in its forward position to hold the margin of the upper in its lasted position while the driver is released by the tripping of the latch 29u to insert a fastening through the margin of the upper and the lip in the manner described (see Figs. 12 and 13). Thereupon the various instrumentalities are returned to their initial positions and a new portion of the shoe is presented to the operating instrumentalities preparatory to the next upper tensioning and fasten- .i

ing inserting operation.
