FASTENING-INSERTING MACHINE.

Application filed December 13, 1920. Serial No. 430,262.

T 0 all whom it may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Fastening- Inserting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indieating like parts in the several figures.

This invention relates to fastening inserting machines and more particularly to machines for inserting fastenings to secure together shoe parts, as for instance, uppers to insoles as a preliminary to inseam sewing of uppers to the insoles of welt shoes.

A machine commonly used for the purpose of securing the uppers to the insoles of welt shoes by means of fastenings is that known commercially as the Goodyear upper stapler which is in general of the type disclosed in United States Patent No. 1,164,784, granted December 21, 1915, on application of John W; 'Cosgrove. In the operation of this machine staples ofauniform length are made'and inserted throughout the operation of securing uppers to insoles, the length of the staple being such that an effectiveclinch of the fastening is secured in the thickest portions of the work being operated upon, while in the thinner portions there is a slight excess of staple length in the clinched portions of the staple fastenings. No attempt has heretofore been made to provide a ma chine of this type with means for adjusting the length of fastenings in accordance with the requirements of the work, though it has been proposed to do so in other types of machines which make and drive fastenings but with very indifferent success due largely to the fact that in attempting to provide for adequate response to variations in the thickness of the work the machines became so complicated as to be prohibitive from the standpoint of expense in manufacture and maintenance and also uncertain, unreliable and inefiicient in operation.

It is an object of this invention to provide an improved machine for inserting fastenings suited to the controlling characteristics of the work'constructed to operate with a high degree of rapidity and efliciency, to be especially sensitive to the requirements of the work, and at the same time free from the disadvantages which have characterized prior constructions.

It is a further object of this invention to provide an improved machine for securing uppers to insoles in the use of which the fastenings will be automatically varied in length in accordance with the requirements of the work, thus rendering the machine more readily adaptable to different kinds of work and enlarging its'field of usefulness without. sacrificing any of the advantages which inhere from the use of the present commercial machine. I Important features of the invention relate to a fastening inserting machine of novel organization in which the feeding means for tlge wire stock is operated to feed a fastening length of wire uniform in amount throughout the operations of the machine followed, under certain conditions, by'correction or adjustment in accordance with the requirements of the work at the point. of fastening insertion.

In another aspect the invention comprises a fastening inserting machine in'which the feeding means for the wire ,stock' is operated at the end of eachcycle to feed always I the same length of wire for the fastening 1 which is tovbe formed and driven in the next succeeding cycle, the construction and ar'- rangement being such. that correction or adof operations of the machine and merely the corrective feed is provided for at the beginning of the cycle in which the fastening is driven, it is clear that the operator does not have to wait for a fastening'at the point of fastening insertion and that the machinecan be maintained at a high-point of speed and efficiency.

7 The invention contemplates also theiprovision of a fastening inserting machine having both the wire feeding'means and the cutting means for the wire adjusted in accordance with. the requirements of the work at the point of fastening insertion, whereinthe wire feed mechanism is operative to feed a certain predetermined length of wire which ustment in the fastening length is made at is uniform throughout all the operations of the machine and which provides a fastening that is at the extreme end of the range of fastenings, as to length, for which the machine is designed, and in which corrective or adjustive feed of the fastening stock may take place subsequently if demanded by the requirements of the work at the point of fastening insertion.

In a preferred form of the invention the wire feeding means is operated at the end of each cycle of operations to provide a fastening length of stock corresponding to the shortest fastening that the machine is designed to make and drive, provision beingfmade to add to the fastening length at t-hebeginning of each successive cycle should such an adjustment be necessary to suit the requirements of the work as measured at the point of fastening insertion.

Important features of the invention relate to improvements in the organization of a machine designed to insert fastenings through the uppers of shoes and into the upstanding ribs or lips of insoles to secure these parts together preliminary to inseaming operations on welt shoes in which provision is made for variations in the length of fastenings as fastening inserting opera tions proceed progressively along the sides of the shoes and around the toe portions thereof where the requirements ofthe work may vary considerably, due to differences in thickness in closely adjacent portions and especially if toe stiffeners or boxes are used at the toe portions of the shoes.

Other features of novelty which contribute to the carry-out of objects of the invention hereinbefore enumerated, or of other objects of the invention which will be appar ent from a consideration of the disclosure of the invention in the specification and drawings, will be pointed out in the following detailed description and included in the claims, and it will be understood that it is my intention to cover by claims in this application all that is herein disclosed of my invention.

Fig. 7 is a detail view of the wire feed mechanism of the machine shown in Figure 6 and Fig. 8 is a detail View showing the work clamped for the insertion of a fastening.

For the purposes of illustration the invention is shown embodied in a Goodyear upper staplii'ig machine designed to secure the uppers of shoes to the upstanding lip or rib of insoles, the machine being of the type disclosed in said United States Letters Patent No. 1,164,784. It will be understood. however, that the invention is not limited to the type ofmachine shown in said Let ters Patent but that important features of the invention may have other and various applications and uses. Referring to Fig.- ures 1, 2 and 5 of the drawings, it will be observed that the work is presented to a nozzle 8 through which fastenings are driven intothe work and properly clinched by an anvil member 10. Then the work is presented to the nozzle and the machine started in operation, the work is first clamped securely between the nozzle and the anvil not only to hold the work during the insertion of fastenings but to measure its thickness at the point of insertion so that faste'nings of the proper length may be in serted as will be hereinafter fully described. As shown, the anvil 10 is fixedly carried'by a head 12 s'lidable in guideways provided by a stationary portion of the frame ll. Secured to or integral with the head 12 is a projecting arm 16 through which passes a bolt or rod 18 having an abutment 20 between which and the arm 16 is a spring encircling the rod 18 and providing for a yielding application of clamping pressure on the work. so that work of'varying thickness may be operated on. Pivoted at 24 is a lever 26 connected to operate the anvil 10 through the rod 18 and having its up er end movably attached by adjustable link 27 to the power driven lever 48. There is thus provided an anvil automatic-ally operated alternately to clamp and release the work and serving in connection with the nozzle 8 as a'work measuring means. The timing of this part of the mechanism is such that the work is first securely clamped during the insertion of the fastening and is then released to permit of the work being repositioned for the insertion of a fastening in spaced relation to the preceding fastening. As shown, the wire stock for the fastenings is fed between corrugated feed rolls 2S and 30 I) through a guide block 32 -(Fig. 5) and over an inside former 34. In the construction shown, the end of the guide block 32 serves also as the stationary cutter. In other words, its end 36 presents asmooth, hardened surface with which there co-operates a movable cutter 38 attached to the outside former 40. It will be clear that after the wire has been fed in position over the inside former 34, movement of the outside former 40 in operative direct-ion will cause the cutter 38 to sever a length of wire .at the instant that the said length of wire is pressed against the. inside former 34 by the forked ends of the outside former. Continued movement of the outside former will bend the wire into staple form about the inside former which is then retracted out of the path of a driver, not shown, which moves down through the outside former to drive the staple into the work presented against the end of the nozzle 8. For operating the outside former there are provided rack bars 42 integral with or securely attached to the slide 44 at the forward end of which is the outside former 40. Meshing with the rack bars are segmental gear members 46 at the lower end of a lever 48 pivoted at 50 in the machine frame and having at its upper end a roll 52 movable along the cam path 54- in the cam member 56. For operating the driver in properly timed relation to the outside former, there is provided a slide 58 to which the driver (not shown) is fixedly connected, the said slide havingrack teeth 60 which areconstantly in mesh with a segmental gear 62 at the lower end of lever 64 pivoted at 66 in themachine frame and having a roll 68 movable in a cam path 70 in the cam member 56. Pivoted at 7 2 in the frame of the machine is a lever 74 which carries atone end a roll 76 for movement along a cam path 78 in the cam member 56. Pivotally mounted at 80 to the other end of the lever is the upper end of the inside former 34 above described. Pivoted to the lever 74 intermediate of its ends by means of a universal joint furnished in part by the plate 82 is-a rod 84, the lower end of which is pivotally secured to awheel member 86 which is freely rotatable on the shaft 88, the said rod being adjusta'bly secured to said wheel by means of a block adjustable along the slot 90. t/arried by the wheel member 86 is a set of pawls, shown at 92 in Figure 7, which are held constantly pressed against the teeth of a ratchet wheel 94 by means of a spring 96. It will be clear that as the pawls are moved in operative direction by the wheel member 86 that the ratchet 94 will be rotated and with it the shaft 88 to which is secured the feed roll 30 referred to above. Fixedly attached to .the shaft 88 is a gear wheel 98 which is constantly in mesh with a gear 100 (Figs. 1 and 7) on a stub shaft 102 which carries also fixedly attached thereto the small feed roll 28 which isin posit-ion to c0-operate with. the large feed roll 30 in securing intermittent feed of the wire stock. The operation of the mechanism thus far described consists in feeding the wire at proper intervals through the operation of the rolls 2 8, 30 through the guide member 32 and across the rear edgeof theinside former 34-,

s oo'rvetwi1reerenc ter Patentt Csgo ,"o hcl f e may be had for a more detailed description of the construction and mode of operation of the said mechanism. j v

It is to be observedfhowever, that there is no provision in the machine disclosed in said Letters Patent for suiting the length of staple to the thickness of the work, asthis latter characteristic varies along various portions successively presented for the insertion of fastenings. In the illustrative mechanism of Figures land 2, the wire is fed by the feed rolls 28 and 30 always for the longest staple that themechanism is designed to make and'drive, the said feeding of the wire taking place 'at the end of each cycle of operations. Then as the work is measured at the beginning of each cycleat the point where the fastening is to be inserted, the wire fed is adjusted, when necessary, at the, beginning of the cycle and in accordance with the thickness of the work by subtracting from the length fed in the preceding cycle an. amount determined by the measurement-of the work in thejcycle in which the fastening is to be. driven. In

order to vsubtract fromthelength fed by the v feed rolls, mechanism is provided for reversing them in their rotation and. feeding back a measured amount determined by the thickness of the work. A specific embodiment of this mechanism willnow be described. Secured to a projection 104 extending from the head 12-is a boltv or connecting rod 106 connected by means of a pivoted link 108 to a slotted member 110 carrying in the slotted portion thereof a block 112 which furnishes an abutment or shoulder 114 for engagement with a pin 116 in a bell cranklever 1-18 pivoted to the frame of the machine and held-yieldingly in its position of rest by a spring 120 which operates-for the purpose in a well known manner. Pivoted to the free end of the bell crank 118 by means of a universal joint is a link which is in turn pivoted by a universal joint 131 to a wheel member 132 looselymounted on the shaft 88. Carried by the wheel member 132 is a pair of pawls 134 constantly pressed by means of a spring 136 toward ratchet'wheel 138 securely attached to the shaft 88, the pawls being held normally out of contact by a stationary shield 139, part of a larger shield 141, so that ratchet wheel 138 and shaft 88 and feed roll 30 may be turned by ratchet wheel 9% in the normal regular feed from operation of lever 74. It will be observed that the shoulder or abutment 11 1 onthe block 112 is not normally in contact with the pin 116 in the bell crank 118, the arrangement being such that the anvil 10 may be spaced from the nozzle 8 to permit of unobstructed introduction of the work between the anvil and the nozzle andto permit of movement of the anvil toward the nozzle to clamp the thickest work that the machineis intended to operate upon without in any way effecting movement of the bell crank 118. Under such conditions the wire will be fed for the longest staple by the operation of the rolls at the end of the preceding cycle. If, however, the work at the point where the fastening is to be driven is of a thickness which does not require the longest staple then the anvil 10 in its movement toward the nozzle 8 will measure and accurately determine the clifference between the longest staple which the machine is adapted to drive and the staple which should be inserted to meet the requirements. Such measuring movement of the anvil 10 will-be transmitted to the bell crank 118 through the abutment 114 striking the pin 116 as above described. Through the connections already described this movement of the bell crank 118 will cause a slight rotation of the wheel member 132 whereupon the ratchet wheel 138 is moved in the same direction and with it the shaft 88. to carry the feed rolls 28 and 30 in a direction reverse from normal whereby the length of wire which was fed at the end of the preceding cycle is fed back slightly the required distance to provide the proper staple length. It will be understood that means is provided to release the pawls 92 from the ratchet wheel 94 at the proper time so as to permit of the reverse movement of the shaft 88 and hence of the feed rolls 28 and 30. If preferred this means may be a stationary shield similar to that shown at 139 in Fig. 2, so arranged that at the end of their return or idle stroke the pawls 92 are lifted from the wheel 94.

Means is preferably provided for adjust ing the cutting mechanism in accordance with variations in the lengths of wire fed by the feeding mechanism as finally determined by the work measuring or caliper ing operations of the anvil and nozzle. Preferably, the wire cutting means is adjusted simultaneously with the adjustment of the wire feed at the beginning of the cycle. As shown, this adjusting means for the cutter comprises a lever or bell crank 14:0 pivoted at 142 on the frame of the machine and having a pin 1% intermediate of its ends and located in the slot in the member 110, an abutment or shoulder 146 beingprovided on the link member 110 for co-operation with the pin 1 14: in a manner exactly similar to the co-operation between the shoulder or abutment 11st and the pin 116 in the bell crank 118 as above described. In the illustrative construction, the lever 140 is held by a spring 1&8 with its lower end in abutting contact with a stop in the form of a set screw 150 set in a bracket attached to the machine frame. It will be observed upon inspection of Figures 1 and 5 that the lower ends of the lever 140 is slotted as at 152 to provide a cam slot which receives a pin or stud 15 1 projecting from the wire guide 32. The construction and arrangement of this part of the cutter adjusting means is such that the wire guide 32 is moved toward or from the inside former 34 to provide -for a longer or shorter staple having legs or prongs of equal length and in accordance with the, adjustment of'the wire feed which follows the work measuring or calipering operationabove described. It is clear that if the cutting means remained always in the same position irrespective of the length of wire fed by the wire feeding means that a decrease in the length of Wire fed at any given time would decreasethe length of that leg of the staple on tlie side of the inside former 34: which faces away from the end of the wire guide 82, while the leg or prong of the staple on the side of the inside former 3 1 which faces the end of the wire guide 32, would remain the same length in all of the staples. Hence, the wire cutting means is adjusted each time the length of the staple wire is altered. Moreover, since the change in the length of the staple must affect both of the legs or prongs, it is clear that the adjustment of the cutting means which decides the length of only one prong is only half ofthe adjustment of the wire feeding means. This difference in the amount of adjustment is arranged and taken care of in the cam at the lower end of the lever 1 10, the construction being such that the wire guide is controlled positively and moved the proper distance in accordance with the requirement of the work.

As above stated pins 116 and 144: are not subjected to the influence of the anvil 10 during the initial movement of the anvil into work clamping position, the pins being, in the normal inoperative position of the machine, equally displaced from the forward ends of their respective slots in the link 110, but atv a certain point in the advance of the anvil into work clamping po sition this lost motion is fully taken up and the shoulder at the end of each slot presses against the corresponding pin so that as the after adjustment of the wire guide andof the feed rolls will have prongs -or le-gs of unequal length, this is considered unimportant,

all subsequent staples for the given'thicle ness of work being perfect and the difi'erences in any case being relatively slight since the variationsin the thickness ofthe 'work'along 'each'side of the shoe are ordinarily not great in amount. v

As stated above the end 36 ofthe Wire guide 32 serves as the stationary cutter during cutting operations, a movable cutter 38 cooperating therewith to sever the wire; In prior constructions the cutter 38 has usually been carried fixedly by the outside-former. In the illustrative construction the cutter 38 is pivotally carried at its upper or rear end by the outside former 40 and a spring 156 is provided between the side of the former and the movable'cutter 38 to hold the latter constantly in contact with the end 36 of the wire guide. 32 with which it co-operates to out the Wire in every adjustable-position of the latter.

In the illustrative embodiment of the second species of the invention the wire is fed the same predetermined amount at the end of each cycle of operations to make the shortest staple that the mechanism is designed to make and'drive and then at the beginning of the succeeding cycle this length of wlre 1s added to, or in other words, in,- creased in length if a longer staple is required by the work measured at the point of insertion of the fastening. In the con struction shown in Fig. 3, the mechanism for feeding the wire stock at the end of the cycle through lever 74, rod 84 and ratchet wheel 94, and the mechanism for making and driving the staple is the same as in the construction above described. Moreover, the means for. adjusting the cutting devices is the same and controlled in I the same way through the lever 140. There remains to be described the specific mechanism for adding to the length of the staple sectionwhen a staple longer than the'minimum is requiredl' As shown, the adjusting means for. the wire feed comprises a bell crank-160 operated in the same way'as the bell crank 118 of Figure 1 buthaving at its free end a block 162 pivoted therein on atransverse axis and perforated to'receive' slidablythe upper end of a rod 164, which rod is provided with teeth 166 which face upwardly so as to'be engaged by a pawl 168 projecting downwardly from a lever 1'70 pivoted to the end of the bell crank 160 at 172 and carrying a roll 174 at its free end for co-operation with a'face cam 176 on the cam block 6, being held constantly incontact with the face cam-176by a spring 178. The lower end of the rod-164 'is pivotally and adjustably connected to a: pawl carrier 180. which carries pawls 182 held constantly in contact with the teeth onthe,

ratchet'wheel '94 by means of asp'ring 18 6,

the said ratchet being fixedly secured, as

above stated,-t-o shaft 88gup0n which the feed roll 30 is also secured. It will beclear that upon downward movement ofthelaterally-extending arm'ofthe" bellzcrank 160, the pawl 168 will be-moveddownwardly and away from the teeth on'the rod 164 thus 7 skipping some of the teeth, the number thus skipped depending on the measuring movement of the anvil-after the :block 112 'en. f

iubsequently cam 1'76 actuatesthelever -17 and'causes the'pawl 168 to engage 'the proper tooth on bar 164 and force the-latter downages with the pin 116 in bell crank 1 60.

wardly so that the pawl carrier 180 will be rocked to cause rotation of the ratchetwheel 94'and of the shaft 88 and thus of the feed roll 30 to give the latter such additional feeding movement as will cor-respond with the increase of staple length requiredby the -work measured at the point of insertion,'* if up the lost motion, the anvil initiates movement of the lever 160 and the link 164 downwardly to operate 7 the ratchet wheel 94,

thereby causing an addition feed of the wire'double the amount by which the'work at the callperedpoint exceeds the minimum in -thickness. F urthermo-re the combined equal to the movement of-the anvil after the shoulder 146 on the link 110 "contacts with the pin 144 carried at the *upper end of the adjusting lever 140for the wireguide 32. a

It will be understood that according to this construction the chiefpart or all of the sectional wire for the staple-is fed at the end of the cycle and that tliencorrec; tion is made at the beginning of the suc* ceeding cycle if the work requires a longer staple than 'the minimum size": whichthe mechanism is designed top'rovide. Thus the time required in feeding the wire at 0118 beginningof the cycle is considerably shortened and thelength of time that thework isheld by the machine previous to the-insertion of the fastening is reduced permitting a considerable speedingup of the "mabe driven in that cycle of operations.

in accordance with therequirements of the work'at'the point wherethe fastening is to beinserted. However,'tl1e whole wire feeding operation is performed at one time instead of being divided into two steps as in the constructions described inthe foregoing specification and in this construction,

moreover, the entire feeding movement of the {feed rolls takes place atthe beginning of the cycle so that there is a slightly longer period of time during which the work is under the control ofthe machine before the insertion of the fastening. On the other hand, the mechanism which embodies this feature of the invention is simpler in construction and possibly less likely to require attention on thepart of the operator or of the repairman. As shown in Figure 6'the bell crank -190 is exactly ;similar -in its mounting and mode of operation as the bell crankllS in Figure 1. It has pivoted to its free end by a universal joint a rod 192 which-is in turn pivoted 'at-its'lower end to a shield member 194: (Fig. 7) pivoted at 196 upon-the wheel member 86,-theshield having a portion 198 which overlies ,the teeth on the ratchet wheel 94. Theconstruction and arrangement of the shield and of its operating parts are such that the teeth'on the ratchet wheel 94 are unobstructed for engagementby the pawls 92 when the longest staple is demanded bythe thickness of the work. On the other hand, as the anvil 10 movestoward the nozzle 8 from a predetermined point of separation corresponding to the greatest thickness of the work which the machine is designedto operate upon, the shield 198 will-be shifted downwardly toward the pawls so that the latter will ride up on the shield in moving to initial position and hence mustmove off of the shield before they can engage'the teeth of the ratchet 94, the timeo-ccupied in contact with the shield having the effect of shortening'the operativestrokeof the pawls, thus lessening the length of wirefed by the feed rolls. It will be clear-that the further the shield 198 is moved downwardly the shorter will be the operative stroke of the pawls and hence the shorter will be the length of wire that is fed-for the staple to As in the preceding constructions, the movement of the combined wire guide and cutter 32 corresponds exactly to the: movement ofthc anvil subsequent to the time that the shoulder 146on-the link -1l0 comes in contact with the pin leg-while the adjustive movement of the feed rolls during the sametime is twice the distance of the said movement ofthe anvil. It willbe observed that the feed rolls, according to this construction, make but one feeding'movement to obtain the staple length suitable for the work which has just been measured. However, the lengthening of the time that the work'is held=by the machine prior to'the insertion of the fastening is considered to more than offset any nother advantageslpossessed by this species of the invention over thegconstructions describedearlier-in the specification and hence, it is preferredto use a-mechanism inwhich the wire is fed at the end of the cycle and a correction made iii-minimum timeat the beginning o-f-thesuceeeding cycle. It will be understood, moreover,

that the features 'ofthe-invention which relate to the-means for feeding and cutting wire stock may'have other usesand applications than that herein illustrated and that the invention is limited only bythe scope of the'claims hereto appended.
