ASSIGNORS TO UNITED SHOE IvIACHIITERY, CORPORATION, OF EATER-SON, NEW JERSEY, A CORPORATION OENEW JERSEY FASTENEE-lll'fSE-RTINQ MACHIFNE Application filed September This invention relates to fastener-inserting machines and is illustratedherein as-em bodied in a machine for lnsertlng blind or shoe upper, and with its barrel'clenched between adjacent layers of the shoe up-per so thattheflange of the eyelet appears on the outside of the finished shoe. 'The term invisible eyelet, on the other hand, is applied to aneyelet having its flange lying upon the lining or facing of the shoe, and with the entering end of itsbarrelrclenched between adjacent layers of the work so that the eyelet is not visible on the exterior of the shoe, The

present invention is applicable to machines for inserting both blind and nvisible eyelets. As a matter of convenlence 1t Wlll be described herein withrelati'on to the insertion of invisible eyeletswith the understanding, h oweveig that this is done Without any 1ntention of limiting the invention thereby' United States Letters Patent No. 1,271,721,

granted July 9, 192 8,upon application of ivelier Shaw, disclose fastener-inserting 1 machine provided with an expansible setting toolcomprisinga plurality of relatively movable sections, each carrying a portion of the clenching surface of the tool. This ekpan sible tool is arrangedto receive an eyelet from the racewayof the machine and isthereafter inserted through alacing hole in one or more layers of the work, and then spread v apart bvanexpander while its clenching surface is between the layers of thew'ork'so' as to put the tool into c-lenchingcondition.

work and will lengthen the life of the expansible settingtool, as compared with that of expansible setting'tools heretofore used, by minimizingthe danger of damage to the tool, for example by foreign material, particularly chips punched from shoe stock, caught between the members of the tool and thus causing the tool to be sprung and broken.

In accordance with the foregoing, the expander provided for the purpose of spreading the 'expansible set to condition it for fastenerclenching is in the illustrated inachine, housed within a tubular punch and the punch and expander aremovedto'getherto feed the work from punching to fastenerinserting position, the punch beingmaintained in engagement with the work throughout the feeding movement and thus insuring that the hole punched in the work is brought accurately into alinement with the expansible setting tool. In order to control the relative position of the clenching surface of the expansiblesetting tool and the layers of the work when the tool isexpanded'to clench an eyelet, the illustrated machine-isprovided with an improved abutment located closely adjacent to and surrounding the punch, its position at the time of the insertion and clenching of each eyelet being controlled by a stop fixed against movement toward and from the work, but conveniently adjustable in accordance with the varying requirements of difierent kinds of stock. This abutment is held away from the work during the'feeding movement and is located at a predetermined position during the clenching operation by said" stop, thereby limiting movement of the stock as the eyelet isintroduced and during the clenching operation withoutinterfering with the proper action of the clenching tool. During the return movement of the punch, preparatory to the punching of another hole in the work, this abutment is withdrawn Further to assist in the accurate control of the stock and the expansible setting tool, movement of the latter in the direction of the stock is positively limited,-prior to the expanding of the set, and the expander is positively locked agamstmovement away fromthe set while ill) the set is brought to and maintained in expanded condition. To facilitate the introduction of the clenching tool both into the eyelet prior to the insertion of the eyelet into the work, and into the work prior to the actual clenching of the eyelet, the entering end of the expansible setting tool beyond its clenchin g surface is gradually reduced in diameter or tapered. Thus the illustrated setting tool is provided with a substantially dome-shaped end, the clenching surface being madeup by a series of facets formed upon the relatively movable members of the expansible setting tool and extending from the portion of maximum diameter in a direction away from the entering end of the setting tool.

To prevent damage to the eXpansible tool by the chips punched from the work, the illustrated expander is utilized also as a chip ejector, being spring-held so that it can yield during the punching operation and, as the locality of the punched hole passes beyond the punch block during the feed, springing forward and ejecting the chip. Still referring to the illustrated machine, the ejected chips are caught by a chip collector and conducted away by a suitable conduit so that the possibility of a chip being caught by the ex pansible setting tool and thereby damaging the tool, is eliminated.

Further to protect the eXpansible setting tool, means is provided for at least partially withdrawing the punch from the work before the setting tool is introduced. After the completion of the work-feeding movement, the punch is moved so that its punching end is located somewhat beyond the limit of movement of the expansible setting tool, preferably intermediate between the outer and inner surfaces of the layer of the work through which the eyelets are not to pass. 7

lVhile the illustrated machine, which comprises a preferred embodiment of the invention. includes all the foregoing features. it should be understood that this is not in all cases essential and that at least some of the advantages of the invention may be attained by other mechanisms. illoreoveiz in various of its aspects, the invention is not limited to fastener-inserting machine organized to insert invisible eyelets, but is of use in connection with other machines.

Vith the above and other objects and features in view, the invention will now be described in connection with the accompanylng drawings and pointed out in the claims.

The illustrated eyeleting machine embodythe present invention has a sliding head carrying a punch operated by toggle mechanism to punch a hole in the work and then moved horizontally to feed the work to eyelet inserting position. the eyelet which is taken from a raceway then being introduced from below and clenched in the hole formed in the work by the punch. After this the punch is withdrawn from the work and moved horizontally in the reverse direction to complete the cycle of operation of the machine. An eyelet inserting machine of this type is shown in United States Letters Patent 1.228,?69 granted June 5, 1917, upon an application of Perley R. Glass. Since machines of this type are well-known in the trade, it has not been considered necessary to make a detailed disclosure of all the mechanism of such a machine. For further details than those disclosed herein, reference may be made to said United States Letters Patent 1,228,768.

The illustrated machine. as best shown in Figs. 1, 2, 3 and 5. is provided with the usual work support 2. punch block 4. edge gage 6, and presser foot 8, as well as with a sliding head 10 guided in its reciprocating movements by a pair of rods 12 and 14. Mounted for reciprocating movement in the sliding head 10 is a punch bar 16 which is arranged for vertical movement by means of toggle mechanism 18. 20. A vertically reciprocated shaft 24 carries a hollow eyelet supporting tool 26 with a conical top 27 arranged to support the flange of an eyelet. Telescopically mounted within the supporting tool 26 is an expansible spindle and setting tool 28 arranged, as shaft- 24 is moved upwardly, to pick an eyelet from the end of a raceway 30, which is given a horizontal. reciprocating movement by link and lever mechanism 31v into and out of the path of spindle 28. A hopper 32 supplies eyelets to the raceway 30.

34, illustrated as'8 in number. These slots are closed together at their-upper -ends 36, as shown in Fig.9, except during the actual clenching operation when they are spread as in Fig.7 6. 'The upper end of the. tool,

considered as a whole, is ,of agradually tapered or dome-shaped formation, as shown at 38 (Fig.9), with a clenching surface 40 extendingifrom the portion 42 of maximum diameter in a direction away from the end of the tool. This clenching surface is made up of a group of facets '44 formed upon the members 46 into which the tool is'divided by the slots 34.

Half-way between each pair of successive slots the clenching surface is formed with a sharp ridge 48 'whichserves to split the entering end of the eyelet barrel, thus insuring a symmetrical clencln Centrally of'the end of the settingtool is an opening 50 (Fig.

2) arranged to receive the conical end 52 (Figs. 4 and 6) of an expander 54- housed within a tubular punch 56 carried by punch bar 16. At the appropriate time in the cycle of operation of the machine, the-end52 of the expander 54 enters the hole 50 in the-end of the spindle or setting tool 28, and, by relative movement of the expander 54 and'the setting tool 28, sp'ringsthe members 46' of the setting tool apart bringing the clenching surface40- into expanded clenching condition between adjacent layers of the work.

While the expansible setting'to'ol 28 is maintained in this condition, the eyelet supporting tool 26, with an'eyelet resting uponits upper end 27 and surrounding spindle 28. moves upwardly forcing the entering end of the eyelet, barrel against the expanded jclenching surface 40 and clenching-the eye let, as" illustrated in Fig. 6, betWeen ad acent layers of the workL It should be noted 'thatthe work in which invisible eyeletsare set ordinarily consists of at least three; or more layers) (theupper leather, the lin ng or facing, and'the eyelet stay), the eyelets passing through the lining or facing and the eyelet stay and being clenched beneath the upper leather, as-shown in Fig. 6. On

account of .the relatively small scale on which Figs. 3, 4 and 5 are drawn, no attempt is made to differentiate between the lining or facing and the eyelet stay in those figures, the disclosure being, 111 this respect, d1a

/ grammatic.

I In order to control the punch 56 duringthe'int'roduction and clenching of the eye- -.let, and toprevent damage to the eyelet or to the expansible setting tool 28,. means, which will now be described, is providedfor at least partially withdrawing punch 56 from the work, afterthe conclusion of the feeding of the work and before the insertion of the eyelet. For this purpose a collar 58 is secured topunch bar 16, the upper surface of this collar forming a stop co-operat- .111 with a stop 60 formed as a, lug upon a slide member 62 connected by a screw and slot. connection 64 with a slideway 66 formed ina block 68 to which toggle member 20 is pivoted. Block 68 is slidably mounted on punch bar 16, its upward moveinent being limited by a collar 70 secured thereto. A-spring 72 urges stop 60 to the left, as shown in Fig. 3. A spring 74, surrounding the upper portion ofpunch bar 16, bears at one end in a socket 76 formed in the sliding head 10 and at the other, end against a collar 7 8 secured to the punch bar 16. Spring 74 presses collar 58 against-stop 60 when the two are in alinement (as shown in Fig. 3), and when stop 60 is moved to the right (as shown in Fig. 4) .out of alinement with collar 58, lifts thepunch bar until collar 58 engages the .body portion of slide member 62. The distance which the punch.

bar 16.is thusliftedis enough to withdraw the punch 54 sufliciently to prevent it from interfering with the expansible settingtool 28 duringtlle introduction or clenching of the eyelet.

In order to disengage stop 60 fromcollar 58 at an appropriate. point in the cycle of operation of the. machine, slide member 62 is provided with an end surface 80, arranged in alinement horizontally .with an adjustable stop member 82 carried by an arm 84 (Fig. 2) secured to raceway 30, and positioned, as the raceway moves to the right after the taking of an eyelet therefrom by the spindle or expansible setting tool 28 and after the conclusion of. the feeding movement of the work but before the introduction of the expansible setting tool 28into the'hole in the work, to

I force slide member 62 to the right, thereby disengaging-collar 58 and stop 60 and permitting spring 74 to raise punch 56 a distance somewhat greater than the thickness of the layers of the work through which the eyelet barrel is to pass. Before the return: movement of the punch '56 to punching position, toggle 18,20 is broken and thereby lifts block 68and slide 62 to such. an-extent that-stop 60 can be moved back by spring 72, intovertical alinement with collar 58. so that when the toggle is again straightened stop 60land collar 58 will engageeach other and punch 56 will be forced .down through'the; work again st the surface of punch block 4.

In order to prevent-damage to;the expansible setting tool 28 by achip punchedfrom i end with a collar 88 a the work, the expander 54 is made to serve aleo as a chip ejector. For this purpose it is backed up by a rod 86 (Figs. 3 and 4) housed within punch bar 16 and provided at its upper nst which engages a s1. ing 90 also housed within punch bar 16 and hearing at its upper end against plate 92 secured to collar 78 by scews 94. Th

expander 54 yields against the compression ing 90 during the punching operation punch 56 beyond the end of punch block 4, expander snaps forward under the influence of spring 90 and e ects the chips punched fi'OllltllG work. These are caught in sage of the conical end of ejector 54.

In order to control the position of the combined chip ejector and expander 54, a lever 108 is tulcrumed at 110 2) to plate 92. A sprii 14 hearing at one end against a lug I 116 carried by plite92 and at the other end against lever 16S urges the latter in aclockwise direction, as viewed in ig. 2, and therebv tends to hold the torward end of lever 168 in engagement with the upper end of rod. 86. Carried by a stationary part of the frame of the .iachine is a hardened block 118 having a surface 120 arranged for engagement by a roll 122 journaled in lever S, and arranged, as punch bar 16 moves upwardly un- 1 dcr the influence of spring 74 when collar 58 and stop are disengaged, to lock rod 86 and Wander against upward movement. This shes place shortly hetero the end of the feet nn movement of the punch and, ot course, before the xpansihle setting tool reaches the ":ander '14. it results in an accurate positive po. I ning oi? the conical end ol ct pander 54 so as properly to position the clenching surface 44 of the expansible setting tool 28 to clench the eyelet between the la crs ot the work.

In order to position the work relatively to the expander 54 and expansible setting tool 28, the machine is provided with an alnitment illustrates at 124. provided with a circular opening arranged to receive and surrounding punch 56. Abutment 124 is provided with or carried by an arm 126 'iivoted at 128 to a collar 130 mounted for sliding movement on the lower end of punch bar 16. Screw 132 threaded into collar 130 has its entering end received in a slot or groove 133 formed in punch bar 16, this slot being of such dimensions that, except during the return movement of punch bar 16, it permits free movementot collar 130 and abutment 124. relatively to punch bar 16. A spring 134 urges collar 130 downwardly thereby controlling movement of the abutment 124 in a direction away from the work. To limit this downward movement of collar 130, the latter is provided with a pair of lugs 136 (Figs. 1. and 5) engaging the squared shank 137 and the head 138 of a stop screw 140 threaded into a sleeve 142 pivoted at 144 to sliding head 10. During the feeding movement and during the introduction and clenching of the eyelets, abutment 124 is held in its lowermost position by spring 134, lugs 136 engaging against the upper surface of head 138 of screw 140. During the feeding of the work, abutment 124 is located normally just out of engagement with the upper layer of the work, as shown in Fig. 3. lVhen the eyelet is introduced, however, the upward thrust oi the eyelet barrel urges the work upwardly into engagement with the lower surface of abutment 124 which thus limits the upward movement of the work and prevents the work from moving beyond its proper position relatively to the clenching surface of the expansible setting tool 28. During the return movement of the punch, punch bar 16 is elevated to such an extent that screw 132 bears against the bottom of slot 133. It is with the punch in this position that the machine comes to rest and when at rest abutment 124 may be swung in a clockwise direction about its pivot 128 to permit the removal and replacement of punch 56, or for any other reason. In order to hold abutment 124 alternatively in operative position or swung to the left, arm 126 houses a spring pressed plunger 146 (Fi 3) having a conical end arranged to co-opcrate with either one of a pair of conical openings 148, 150 in collar 130. It will also be observed that when the machine is at rest between operations screw 138 may be swung to the right about pivot 144 and adjusted, if necessary, to position abutment 124 in accordance with the thickness of the stoc to be operated upon.

In order to control and to adjust the. position of the expansible setting tool when the machine is being set up or when a very radical change is made in the thickness ot the work, vertically sliding shaft 24, which is reciprocated by mechanism includng a lever 152 connected thereto at 158 (Fig. 1), houses a rod 160 externally threaded at its lower end at 162 to receive a wing nut- 164 and a lock nut 165, and internally threaded at its upper end, as shown at 166, to receive a thread formed upon the lower end of the expan sible setting tool 28. A spring 168 surrounds the upper portion of rod 160 and bears at its upper end against a collar 169 (Fig. 3) formed upon rod 160, and atits lower end against a surface formed upon a sleeve 170 surrounding spring 168 and threaded into shaft 241. A set screw 17 2 threaded into the upper end of sleeve 170 bears against the eyelet supporting tool 26'and prevents its dis placement. Thus it will be seen that the supporting tool 26 is rigidly carried by shaft 24 while the expansible setting tool 28 may:

telesco e within shaft 24 a ainst the com res sion of spring 168. The expansible setting tively limited by engagement against a sta-' tionary stop 175. Thus it will be seen that the position of the clenching surface 40, when in expanding condition, is positively determined, though adjustable, While the position of the conical end 52 of theexpander 54 is also positively determined and serves as the base with respect to which the expansible setting tool 28'is adjustable. It should be un-' derstood thatonce the expansible setting tool has been properly adjusted it will not ordinarily be necessary to adjust it on account of variationsinrthe work since these variations are taken care of by the adjustment of abutment 124. o

In the operation of the machine (which comes to rest with the eXpansible settingatool 28 lowered and the punch 16 and the abut ment 124-raised, as shown in Fig.2),the work is placed upon the worksupport 2 with the position in which the first eyelet is'to be" inserted in line with the punch 56, the edge ing head 10 moves to the left, punch-56 feeding the work along the work support 2. As

punch 56 passes off the punch block 4, ejector 54 forces the chips from the punch, the chips being caught by the chip collector 96 and be- I ing carried oft through conduit 102. --At this time abutment 124: is positioned slightly above the work. During this feeding movement the raceway 301s brought into posit on so that the endmost eyelet is entered by the expansible setting tool 28, and is received by.

supporting tool 26, theraceway moving then to the rear and to the right, as viewed inFigs.

2 and 4:. After the completion of the feeding movement, and before the expansible setting tool 28 has reached the work, the surface 1 of slide 62 ishit bystop 82, as the raceway moves to the right, and stop 60 is moved tothe right out of engagement with collar 58. Thereupon, punch bar 16is liftedby springfitand punch 56 is raisedsothat its end is out of the way of the expansible setting. tool, which .now enters thehole inthe lower' layers of the work, finally coming torest when lock nut 174 engages stop 175. G011- tinued upward movement of shaft 24; causes eyelet supporting tool 26 to continue its upward movement, the entering end of the eyes let entering the hole in the lower layers of the work and coming into engagement with clenching surface 10 of eXp-ansible setting tool 28. The clenching surface 0 at this time is in expanded condition since these ting tool 28 is expanded by the conical end of 0:; iander A at the time it completes its upward movement, and upward movement of the work is limited by abutment 124i At this time upward movement of the expander. 54 is prevented because the roll 122 is in en'- gagement with the surfaceof the block eyelet barrel. against the clenching surface of the expansible setting tool 28, and causes the eyelet to be clenched between the layers of the work, as shown in Fig. 6. Then shaft 24L starts down and toggle 18, 20 is broken, ele vating the punch bar which carrieswi'th it the punch 56, expander 54, and abutment 12 1. Raceway 30 also moves to the left permitting spring 72 to move slide 62 so as to bring stop 60 into alinement with {collar 58 ready for the'neXt punching operation. At the conclusionof the clenching operation presser foot 8 is moved downwardly into engagement with the work, holdingit against inadvertent movement during return movement of the punch to punching position.
