16 Claims.

Generically this invention relates to machines for uniting layers of material, but it more especially is directed to the type of machine designed for making and inserting metallic fasteners, and

the like, and embodying novel devices and ccmbinations of mechanism for expeditiously effecting the uniting of layers of material such as the soles of shoes, boots and the like.

One of the principal objects of this invention is the provision for a d-evice of this character for making and inserting fastening elements formed from a continuous wire comprising a novel fastener inserting mechanism and unique knife assembly for forming and predeterminedly positioning the respective fastening elements with respect to the inserting mechanism.

An important object of this invention is the provision of a device for making and inserting `fastening elements formed from a continuous Wire embodying novel means for feeding the wire to the cutting or shearing mechanism, maintaining the wire against retraction, and controlling the feeding mechanism to determine and vary the lengths of the respective fastening elements, as desired.

Another important object of this invention is the provision of a device of this character embodying a fastener inserting plunger mechanism and wire feeding mechanism synchronously associated, operating means for actuating said plunger in fastener inserting direction, and means for preventing said plunger moving in the opposite direction until it has entirely completed its limit of movement in inserting direction.

A further important object of this invention is the provision of a device of this character embodying a fastener inserting plunger mechanism, a wire feeding mechanism, a shearing or cutting mechanism, and operating means for effecting 40 simultaneous .operation of said mechanisms during the downward or inserting movement of` the plunger mechanism, and means associated with said operating means for preventing return of the plunger mechanism to its initial position until it has completed its downward stroke, thereby insuring expulsion or" each fastening element from the device, its insertion in the material to be united, and likewise insuring formation of the respective fasteners inte uniform and predetermined lengths.

A still further object of this invention is the provision of a device of this character for making fastening elements from a continuous piece of wire and inserting the respective elements in layers of material to be united such as soles of shoes, means for regulating the position of the soles or material with resp-ect to the inserting mechanism, and additional means for moving and maintaining the anvil mechanism in engagement with said soles or material during the uniting operation.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in accompanying drawings, in which like characters of reference indicate like parts throughout the several gures, of which:

Briefly, it was to provide a machine embodying novel features for making and inserting metallic fasteners in the soles of shoes and the like, comprising a wire feeding mechanism, a plunger fastener inserting mechanism, and a knife or wire shearing mechanism, the latter adapted to form the respective fasteners and successively position each fastener as formed in the path of the plunger mechanism for inserting said fastener in the material to be united, said mechanisms being synchronously associated, a control rod mechanism for moving said plunger in inserting direction, and means associated with said control rod forV preventing its upward movement until the plunger has completed its downward stroke, so that a respective fastener is formed, positioned screw I2, adaptedto` adjustably clamp the lower end I3, of thesubstantially horn-shaped anvil with respect to said plunger, and inserted in theV materials to be united during each downward strokeofgsaid plunger mechanism, that we designed thev device forming the subject matter of this invention.'

vIn the illustrated embodiment characterizing this invention there is shown a frame, A, comprising a pedestal section I, and a top section 2. The pedestal section lis formed with an integral base portion 3, andY in the present instance tapers towards its upperv end terminating in a lateral flange 4. Said frame section is of hollow construction and is formed in its `respective sides with elongated openings 5, and formed integral withV or suitably connected to flange V4, isatableor shelf section 6, on which is mounted frame section 2 bolted or otherwisefsuitably secured thereto. Section 2 is formed with a substantially rectangular base l, which at its free end is formed with a vertical bearing opening 8, in which is mounted movable bushing element 9, terminating at its upper end in split ring I0, and through the meetingends of which is mounted adjusting member Ill, formed on its upper end with anvil or material contacting face I5, which is in Verticalalignment with lower endV I3. Anvil member I4 is adjustable in accordance with the dif- Vferent shapes-and types of shoes or material being operated upon,fasrwill be apparent.

Section 2 at one Vend of base 1, is formed Wit Y vertical standard I6, terminating at its upper end 1in head Il, extending in vertical alignment with The face of head "I'I is formed at opposite edgeswith flange projections- I8, on which is mounted face plate I9, secured to said head by set screws 29,' or other suitable fastening 'means VThe plate I9, is suitably recessed as at -2I, to provide a seat for plunger 22, slidably mounted therein. The extremity of plunger 22,

is countersunk rto rreceive a cam block 23, secured Y by set screw 2li and dowel pins 25, said block exmtends beyond one edge of the plunger, and is vformed 'at its lowerfedge with cam face 26. The plunger point 2l, is formed with head 28, adapted to seat in the complemental countersunk openings formed in saidplunger and cam plate as will be clear Without further discussion.V

22 and edge 33, as at 3l and formed with an opening 32. The upper en d of said plate I9 is recessed as at 33 in which is mounted hold-back ratchetlike nger 34, formed on one side with wire engaging-tooth 35 and on the opposite side with apertured extensionr 36, adaptedtoreceive dowel pin 3l carried by said plate I9. Mounted intermediate the lower end of'elernent 34 and the wall of said recess isspring 38 for holding-tooth 35 in "engagement'with' wire 39 to prevent slippage or withdrawal of the wire, unless moved out of engagement therewith, by the manual movement of end r4i), as will be clear without further explanation.V Y Y Y VThe wire feeding mechanism C, is adapted to be mounted in the recess or countersunk portion V3i, and 'comprises' block 42',formed with flange 43, extending the length of the block at one edge,

, Yand ange portionlill at the lower opposite cor- Iextension 4B rotatably mounted on theY suitably `ner adapted to form a seat for spring 45 engaging the lower end of ratchet finger 46 formed, similar to the finger 3d, on one side with wire engaging tooth lli and onthe ropposite side with securedpin, 49. v'Mounted on the rear surface of Plate I9,is countersunk intermediate'plungerr 51 and is adapted to be forced down by cam 53 and tooth B'I in engagement with wire 39 forces the wire downward a distanceequalto the limit of movement of said mechanism C, as and for a purpose, Vhereinafter more fully appearing.

Mounted at the lower end of recess 3i, Vplate 59 is secured by fastening element 60and is formed adjacent its upper inner cornerV with Vslot BI adapted to register with the diagonal tube 62 formed in plate I9 and constitutes a guide for wire 39 as it is` advanced by feeding mechanismVV C to the wire cutting knife or shearing assembly D-now to be describedi` The lower vend'of plate I9 is formed with a V shapedextension 33, on which is Vmounted a similarly shaped stationary knife or blade element 34, suitably'secured thereto by screws 35. The face of said element 3G is thicker at its upper edge than at its lower edge andis formed with a'curved inclined slotV -69 and with a diagonal slot 56 'slightly enlarged at its upper end as at GS and with itsV lower end'terrninating at Vsaid curved seat.` The edge 6l of said slot constitutes the cutting or shearing edge of said stationary element Sli, which is also formed with asimilar shaped perpendicular slot 38 adapted to receive the plunger point 2T, as vwill hereinafter more fully appear. Y

The complemental movable wire cuttingror f l shearing-blade 69 is movably mounted on plate `lili constructed with an outwardly and upwardlyV extending arm 19, formed at its upper edge with a rearwardly extending projection ii terminating in an inclined contact face l2, and the end of said arm being inclined to form cam Contact surface 'I3 for engagement withV cam surface 26 of plunger block 23. Said arm I9 is formed atV its upper inner edge with plunger contact extension 1rd adapted to reduce the frictional engagement of the plunger with said arm during its recprocas torymovement, as willrhereinafter moreY fully appear.

through aperture YIii of stationary plate 34, and through the lower end of extension t3V to which it is rigidly secured by pin TI. Said pin 'I5 isY Movable blade 69 is apertured at'itsv ylower end to receive pin "i5, adapted to extend formed with opening I8 extending in alignment with slot 68 formed in stationary blade '64.

Movable blade 69 is formed on Vits rear face,

with curved surface 69' oppositely inclined to the complemental seatV B4' rof Yblade Sli which Vit is adapted to engage, and the lower endfQ of said blade below surface 69 isthicker than the portion above said surface. Y in said rear surface with a slot i9V which enters surface 69' and continues through said thickened portion 69'l as anopening extending to the lower edge of said blade YYas will be apparent. Said slot 'I9 is slightly enlarged at its upper endas at 80 similar to slots 66 and68, and the edge 8i thereof constitutes the cutting or shearing edge Vof said blade in conjunction with edge El of stationary blade S4 when said elements are operatively as.

sembled. The upper end of slot 'I9 isadapted to initially register with slot orY guide 62 so as to Said blade 69 is formed receive .the wire 39 when it is advanced therein by feeding mechanism C a distance corresponding to the length of the fastener 82. Fastener 82 is formed as blade 69 is moved to bring slot 'ig into registration with slot 68, which movement of said blade positions the fastener to be acted on by plunger point 2l, as will be apparent as the description proceeds.

f In this connection it will be observed that in forming the fastening element 82, the shearing movement of the cutting edges of Hifi and 69 cuts or shears the wire at an angle and thereby forms fastener 32 with an oppositely inclined edge 83, at each end which is advantageous in eifecting proper clinching of the element in the layers of material E as willV be hereinafter more fully described.

Plate i9 is recessed as at Sil to accommodate arm i3 of movable knife 69 and the hook-like member 85 pivotallymounted as at le and formed with elongated finger portion 'i adapted to en-A gage face 'i2 and maintain knife Se in wire receiving position, and downward movement of cam block 23 is adapted to move arm 'iii to a perpendicular position aligning slot opening 'i9 with slot 68, and the upward movement of cam 23 engaging under the substantially right angularly extending trigger portion S8 causes finger 8l to return arm 7B to its initial position.

Cam 53 extends through .slot E3 in i? and is formed with arm 89 normally resting in a substantially upright position, the upper curved endV of which is adapted to be engaged by the lower end 98 of arm di integrally connected with head F intermediate its length. Slightly spaced from arm 9| is operating rod 92 having its upper end suitably connected to head F adjacent one end thereof, A threaded bifurcated member 93 is mounted on the other end of head F by pin gli and the upper end cf plunger 22 is formed with an end member 55 suitably connected thereto, said end member being formed with threads extending oppositely to the threads of member 93, to which it is detachably connected by nut Q.

l Plunger 22, arm 9i and control pedal rod Q2, ex-

tend through suitable openings in top plate 9'! secured to head |`l by threaded bolt Q8, said plate 91 being also recessed to permit end i8 of wire holder 34 to extend therethrough, so that the same may be disengagedV from wire 39 as desired.

In order to limit the movement of cam 53 when returned to initial position by spring 5?, a pin 99 is suitably mounted in block 55, and in order that said cam may be moved beyond pin out of engagement with wire feeding mechanism C, thereby rendering said mechanism inactive, when repairing or adjusting the machine as desired, a pin led is mounted adjacent the upper end of said camV to form a hand grip therefore.

Pedal rod 92 extends through bearing opening lill in head i'i and a similar opening ||l| in basel t and thro-ugh section 6 and terminates in bifurcated member m2 threadedly or otherwise suitably mounted thereon; Member |62 is connected to pedal arm E83 by pin or bolt |04, one end of said pedal arm i @3 being pivotally mounted on pin |65 in ears iet suitably formed on base 3. Said arm extends through slots |85 formed in base l and has mounted on its free end pedal li'i secured thereto in any suitable manner. One end of spring |38 is connected to anchor clip |63 mounted on rod 92 and secured adjacent clip |82 by nut H6. The other end of said spring is connected to hook l i suitably connected `to flange 4, and is adapted to exert an upward pull on control or pedal rod 32 to normally maintain said rod and pedal |01 in elevated position. It is evident that when |01 is depressed, rod 92, head F, plunger 22 and arm 9| will be impelled downwardly, and in order that said plunger may not return to its initial raised position until it has reached the limit of its downward stroke, a ratchet mechanism G is associated with rod 92, and which mechanism will now be described.

Mechanism C- comprising a plate H2 secured by screws, or any suitable manner to standard 2, and mounted on said plate substantially central of its length secured thereto by a screw or in any suitable manner is a slotted anchor post i3. Ratchet arm lill is mounted in said slotted post substantially central of its length as at H, and is slightly arcuate in configuration with its upper end rounded as at HS and its lower end formed with a face il of ratchet linger H8 and heel |59. Mounted o-n said rod 92 is a cam member 29 suitably secured thereto by set screw EEE, and series of ratchet teeth |22 are formed in the rod adjacent said cam, and adapted to be engaged by nger H8 of arm H4. Said cam i2@ is adapted to engage end l I6 when it reaches the limit of its upward stroke, causing finger H8 to engage the lowermost ratchet tooth |22. A spring |23 is mounted on plate H2 secured by plate E24 and screw |25, and is formed on its free end vwith a lateral catch |25 adapted to engage heel H8 and maintain finger H8 in engagement with ratchet teeth |22 during the downward stroke of rod Q2, as clearly shown in Fig. 13 ci the drawings. When rod 92 reaches the limit of its downward stroke cam 429 engages finger M8 kicking it back and causing catch IZt of spring |23 to engage face if?, and maintaining said iinger out of the path of teeth E22, as clearly shown in Fig. 14, until rod 92 returns to its initial position and cam i2@ again engages surface E causing nger i8 to again engage the lowermost tooth |22 as in the irst instance. While we have shown one form of spring for controlling arm i ifi, it is obvious that this arrangement may be varied without departing from the scope or spirit o-f the invention.

in order to limit the upward movement of pedal lD' and rod 92, a bracket stop member |21 secured by a suitable fastening element is mounted on the inner surface of section i, adapted to be engaged by buifer or shock absorbing medium E28 constructed of rubber or the like suitably mounted in the end of holder |29 mounted on and secured to pedal arm |03, similar to element |1132, and which not only insures a gage for the upward stroke of rod 92, but constitutes a buifer for reducing the shock and vibration incident to the release of pedal |01.

In order that the anvil section l5 may move upwardly and engage the under surface of the shoe sole or other material being united and hold the same in iirin position with respect to opening i9 simultaneously with the downward movement of pedal arm |33, a rod |30 suitably connected at its lower end to arm |93 by bifurcated member to2', similar to arm 92, extends upwardly through a slot in the rear wall of standard with its upper end suitably connected to one end of spring |3|, the other end of said spring being connected to hook |32 suitably connected to one end of arm |33. Arm |33 is fulcrumed on pin i3d mounted in bracket |35 suitably secured to frame section by a bolt or in any suitable manner, and rotatably Vmounted on pin |36 in the end of arm A|33 is roller |31 adapted to engage the end of bushing 9 and elevate anvil member when pedal |91 is depressed as will be clear without further discussion. Spring |3|V 5 is adapted to compensate for different thicknesses of material E, as will be well understood.

Mounted on the upper end of section 2 by bolts |38 is 'a bracket |39 in the upper end of which is mounted casing |69, in which is rotatably mount- 10v ed reel |9| on which is wound wire 39 adapted to Ybe heldin place by nut |42. Wire 39 extends throughv opening |93, through top 91, between the wall of recess 33 and tooth 35, through'feeding mechanism C between fiange 43 and tooth t1, Y and through guide 62 vto knife 69. Tooth 91 being normally in engagement Ywith wire 39, each downward stroke of mechanism C advances said wire into knife 69 a predetermined distance, and

in order to vary the distance the wire is advanced at veach stroke, thereby varying the length of the fastening elements formed by knife mechanism D, it is necessary to control mechanism C accordingly. Therefore, as the bottom wall of opening 32 constitutes a stop for the downward movement or stroke of mechanism C, to vary `the feeding stroke of said mechanism, it is necessary tocontrol and vary the stop Vfor limiting the upward movement of said mechanism C when same is returned to its uppermost position by 3()` `spring 51, and which is accomplished by the 'structure now to be described.

Mounted Yadjacent ledge 52 in block 50 and projecting laterally therefrom is pin |99 adapted to extend through slot |95 formed in flange 16 35 and adapted to engage lug |136 integrally formed with or secured to lever |41, suitably journaled at its lower end on stub shaftV |418, integrally Vformed'with Yor suitably mounted in the edge of plate i9 to which it is secured by nut |99. Le-

40 ver |131 is formed at its upper end with operating handle |56 and with tooth |5| for engage- Y ment with the teeth of curved rack |52 suitably mounted on plate 9 adjacent its upper edge. It is apparent that movement of' lever v|91 and stop lug |46 adapted to engage pin Miti, determines. the upward movement of feeding mechanism C, and therefore, a predetermined setting of lever M1 controls the length of the feeding stroke of said mechanism C and determines the length of the fastening elements 82,

as desired.

In order to regulate the position of the shoe or layers'of `material to be united with respect to the fastener or nail feeding opening 19 and plunger point 21 operating therethrough so as toY insure `a uniform line of Stitching with respect to the edge of such material, a gage or regulating mechanism H is mounted adjacent the lower edge of knife mechanism D, which Y, will now b-e described.

Mechanism H comprisesV a bracket |53 suitablyformed with or connected to standard |6 formed at its free end with a Vertical stub shaft |53 and an anchor slide plate'l55 constructed Vwith an extension |56 suitably formed at its outer curved edge with rack teethr |51, and projecting at an angle rearwardly with its end spaced from said rack is a projection |158 rotatably mounted on said stub shaft |54 and secured inany desiredadjusted position by thumb screw |59. Extension |56 isV formed substantially central of its length with a stub shaft |66, on which is rotatably mounted lever |6| substantially central of its length. The freeV end ofV said lever constitutes an operating handle and the other endV is rounded or ball' pointedfor engagement in thetransverse substantially V-shaped slot |62 formed in the upper surface of slide |63 slidably mounted in recess |64 formed in saidr plate adjacent one edge, said'sli'de be-Y 5. ing formed with a depending projection |65V adapted to limit the retractile ,movement of said slide, the opposite movement being limited by lug |66 suitably formed on extension |56 constituting a stop for lever 16|. Lever |6| adje-*l0 I cent its free end is also formed with operating knob |61. It is apparent that the edge of the material to be united `when placed intermediate anvil l5' and knife mechanism -D will contact Y the end of'sli-de |63, which constitutes a gage V15 or guide settable as desired, to control the points of insertion of the fasteners with respect to the edge of the sole or materials beingfunited. Y

`In order to properly house the parts mountedf in plate |9,'a detachable cover plate |68 is pro- 2Q 7 vided suitably secured by bolts |69 and ,wing nuts |16. c

Operation Although theoperation of theY device Vwuld 251V Y seem to be clear from the above description, it Y might be well to further state that when theV wire has been introduced into the machine passed beyondY finger 33, through mechanism C andV guide 62 with its end adjacent the upperY edge 30 1 ofknife 69 and in alignment withA opening 19; lever |91 having been set according to the length of fastener desired, and gageY mechanism H properly set, and the material to be united positioned on anvil face I5 with its edge in engage- 35 ment with slideV |63, downward movement of pedal |91 will pull down rod 92,;head E', armV 9| and plunger 22. Duringthe downward stroke of said plunger 22 arm 9| engages cam 53 VIVnQV.-

ing feeding mechanism C, and tooth i1 in engage- 40 v t ment withwire 39 feeds said wire into the complemental slots 66 and 19, a distance equal to the downward stroke of mechanism C. When said mechanism has reached the limit of its downward stroke, the surf-ace 26 of cam 23 en-V 45 gages cam surface 23 of arm 10, moving said arm to perpendicularposition and actuating said knife 69, whereby the cutting edges 61 ofthe stationary knife and 8| of themovable knife effect shearing of wire 39 vand forming fastener 56 element 82, with an Yinclined point, and as arm 16 reaches itsv limit of movement, opening 19 carrying the fastener 82 will register with op'en-V Y ing 53 and in'alignrnent with plunger'point` 21` by which time the plunger point has reached the 55 upper edge of said knife mechanism H, and as it continues on its downward stroke itexpels fastener 82 from opening 19 and' inserts it in the layers of material tovbeV united.V The lowerV end of the fastener contacting anvil l5 is clinched 69 Y vany upward movement of said rod, plunger and associated parts until all such mechanisms have reached the limit of their downward strokes;V and as saidr rod 92 reaches such'limit cam |20 with spring |23 effects movement of ratchet Varm 75 lili to inoperative position, thereby permitting said rod to be returned to its initial position. It. will be observed that the action of all of the above. parts takes place during the downward vmovement of plunger 22, and While it is travelling. from its initial position tothe limit of its downward movement.V Upon removalof pressure from pedal till', spring IBS returns said pedal, pedal rod, and plunger to their initial positions and, ready. for another cycle of operation, as will be clear without further description.

It will also be noted that the return stroke -or upward movement of plunger 22 causes cam Z3 to engage and elevate trigger 88 causing finger 8.1 to move arm 'lll to return knife element 69 to its initial position with opening 19 in alignment with guide 62 in readiness to receive the end of wire 39, asin the first instance.

From the above it is apparent that we; have designed a machine for making and inserting metallic fasteners: in shoe soles and the like, com- Vpact in form, embodying novel mechanisms coactingtosever the wire, position the fastener with respect to the inserting mechanism and insertV the same in the materials to be united, during the downward stroke of the plunger mechanism, yet manufacturable at a minimum cost and efcient for the purposes intended. Y

Although in practice we have found that the fcrnrof our invention illustrated the accompanying drawings and referred to in the above description as the preferred embodiment, is the most efficient and practical, yet realizing that conditions concurrent with the adoption of our invention will necessarily vary, we desire to emphasize that various minor changes in details of construction, proportion and arrangements of parts, may be resorted to within the scope of the appended claims without departing from or sacrii'lcing any of the principles of this invention.
