MACHINE FOR INSERTING EYELETS.

Application filed November 20, 1919. Serial No. 339,364.

To all whom it may concern.

Be it known that I, JAMES E. IVTCIXTIRE,

a citizen of the United States, residing at lVeymouth, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Machines for Inserting Eyelets, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastener inserting machines and more especially to means for determining the desired initial positions of the work relatively to the fastener-inserting mechanism. As the description of the invention proceeds it will be apparentthat the latteris applicable to various fastenerinserting operations, but for purposes of illustration the invention is exemplified herein with special reference to its use in the insertion of eyelets as by an eyeleting machine of the type disclosed in an application Serial No. 323,164, fi ed September 11, 1919, by Perley R. Glass.

In machines that act alternatelyto feed the work and; to set one eyelet at a time it'has been the practice, after setting the eyelets in one, quarter of a shoe-upper, to

ters in registration with each other, then prick a hole or otherwise form a markon the other quarter by inserting a marking tool through the last eyelet of the first quarter, and then to set a series of eyelets in the other quarter beginning at the mark located as aforesaid and therefore at the opposite end of the quarter from that at which the eyeleting of the first quarter started, and progressing therefrom. This practice requires considerable time in marking the second quarter, and the output of suchniachines has been'restricted accordingly. Furthermore, the mark, at best, is relatively inconspicuous and more time is lost in placing the second quarter so that, in the judgment of the operative, the first eyelet will be set accurately on the spot so marked.

In order to meet the difliculties peculiar to the problems that arise in determining the initial positions of right and left quarters it has been proposed heretofore to provide eyeletsetting machines with reversifold the upper so as to place the two 'quar-' ble work-feeding mechanism by which the right-hand quarter will be fed in one direction and the left-hand quarter in the opposite direction. This proposition has not, however, found general use since it necessa rily involves the sacrifice of advantages that make one-way feeding mechanism preferable. For example, when the feeding mechanism is reversible the punching, feeding and setting cannot be performed so advantageously, the mechanism is much more complicated, andthe user is obliged to operate on the right and left quarters according to a predetermined order or else to set the feeding mechanism according to whichever quarter is presented to it.

The foregoing conditions are mentioned to show that theproblem of gaging the initial positions of the quarters has been regarcied as one of suflicient importance to warrant sacrificing other desirable features. In attaining the objects of the present invention it has been sought to retain, among other desirable features, the advantages of utilizing the punch to feed the work, of 1 feeding both quarters inthe same direction, and of dispensing with the necessity for marking the second quarter by the guidance of work already performed on the first quarter. so far as I ainfaware no eyeleting, machine has ever been designed tore'verse thedirectionof the feeding motion without sacrificing the feeding function of the punch. on the other hand, no eyeleting machine has heretofore been provided that feeds both quarters in the same direction without putting the user under the necessity of presenting the quarters according to a predetermined order and marking the second quarter by the work that has been performed on the first quarter. A somewhat similar arrangement o f'gages has been proposed for certain hook-setting machines, but only by mounting the gages on a punching and feeding tool so that they encumber the latter and, by their weight, impose additional load on the punching mechanism as well as on the feedinginechanism. This arrangement has disadvantages, two of which to provide improved means for locating the i work such, for example, as the-leading edges of the quarters respectively. To those familiar with the practices" in the fittingroom of a shoe-factory, vit is well known that the eyelet or lacing hook at. the upperend or a series should be relatively close to the upper edge of the quarter whereas the eyelet at the lower end of the series should be more distant from the lower edge of the quarter in order to make allowance for the stock'that is to be lapped with the vamp where the quarters and-vamp are afterward stitched together." Accordingly, when the lower edge of the quarter is the leading edge. its initial position should be further advanced relatively .to the eyelet-inserting mechanism than the upper edge would be when the latter is the leading edge.

A feature of theinvention consists in a device comprising two stationary gaging elements arranged to indicate, respectively, more or lessadvanced positions from which the" leading edges of the quarters should start when eyelets are about to be inserted.

Another feature of the invention consists in organizing the two said gages in such manner that they may be adjusted, for ex ample," relatively -.to each other, and collectively without disturbing .their relation to eachother. Such collective adjusting may involve motionin more than one direction. -For example, according to the construction shown these gages are adjustable collectively in lines parallel to the direction 'offeed and also in lines substan tially transverse to the direction of feed. In a machine-of the kind shown the first of these collective adjustments is useful to maintain the desired relation between the gages and the 'work-feeding mechanism when the'latter is altered to vary the length of the feeding steps, and the second is useful to provide for varying the distance between the median line of the series of eyelets and the longitudinal edge'of the work over which the lacing is to be passed.

Another object of the invention is to provide improved means for gaging the work to insure at all times the proper relation of the gages to each other and to the work whatever the length of the work-feeding steps-"or the distance between the eyelets andthe longitudinal edges ofthe quarters.

, According to the machineshown the workfeeding mechanism is provided with' a regulator by which the-length 0f the feeding stepsmay be varied, and the illustrated gaging device above mentioned is connected to the feed regulator in such inalnner'that whenever the regulator ismoved to alter theeflective range of the feeding mechanism a' corresponding adjusting movement will be imparted automatically to the gages. of that device to compensate for the variation in the feeding motion.

Eyeleting machines of various types, whether provided with a starting gage or not, 'are'usually'provided with an "edgegage or guide arranged to contact with, the longitudinal edge of the work relatively to which the line of'eyelets is located, and,

moreover, such guide is usually adjustable.

transversely of the lines of feeding movement to vary the distance between the guiding edge of th'e work and the line of eyelets. Heretofore, in those machines that include both an edge-guide and a starting gage,- it has been common to make the two latter independent ofeach other so that no adjusting movement of one would affect the position of the other. I have found it to be desirable, however, to adjust the starting gage or gages transversely of the lines of feeding movement whenever the edge guide is so adjusted, in order to maintain uniform relation between the guiding edge.-

of the work and the starting-gage or gages,

under all conditions. In accordance with this finding, therefore, I have provided, as a feature of the invention, a new organi--- zation of the edge-guide and the starting gage-0r gages whereby-the aforesaid uniform relation will bemaintained when the edge-guide is adjusted transversely of the lines of feeding movement, and, according to the organization shown, the transverse adjusting.movement of the starting gages is imparted coincidently .with the corre-" sponding adjusting movement ofthe edge guide. I This not"- only avoids error in respect to the relation-of the elements con-:- cerned, but avoids additionalmeans and an additionaladjusting--.- operation for the start-ing gages, beyond-thoserequired for the edge-guide; A further feature-of theinventionconsists in arranging one or more of the gaging elements so as to bear upon a supporting surface "other than thatto which they are. anchored, in order that they will be amply supported and protected against breakage .or

accidental displacement.

Otherfeatures of-the invention are illustrated by thedrawings and are hereinafter described and. claimed.

vention Fig. 2 is a vertical section through the structure intersected byline 2--2 of Fig. 1;

Fig. 3 is a perspective view including a presser-foot and punch-block and the gaging device in co-operative relation thereto and including also a fragment of work such as the lower portion of the left-hand quarter of a shoe-upper; I

Fig. 4 is a view of variable work-feeding mechanism with connections constructed and arranged to impart to the gaging device adjusting movement to compensate for feedwork-feeding and eyelet-inserting mecha nism included in the drawings An eyeletinserting tool is indicated at 10 and the usual spring-pressed spindle thereof is indicated at 11. These two elements are carried up and down by a plunger 12 arranged in fixed bearingsin the frame of the machine. The'delivery end of an eyelet-raceway is indicated at 13 and the eyelet indicated at 14; is sup-' ported thereby in position to be removed by the spindle 11 as the plunger-12 is depressed. It is to be understood that the raceway element 13 will be retracted from the path of the inserting tool in due time to clear the latter.

The clenching tool is indicated at 15 and is provided with a project-ing central portion 16 that is utilized first to punch a hole in the work, then to feed the worlgand finally to guide the barrel of the eyelet into the work. Fig. lshows the several elements in their initial positions, that is, their positions at the beginning of a cycle of opera tions. The specimen of work shown in cludes a left-hand. quarter 17, an eyeletstay 18 and a lining 19. The work is supported by a raised portion 20 of worlnsupporting plate 21. Anopening 22 is formed in the portion 20 to receive the punch 16 and the upper end of the clenching tool '15. This tool is carried up and down by a plunger 23 and the latter is arranged to slide in a hearing afforded by a horizontally movable feedcarriage 24-. The latter is arranged to slide on suitable guides one of which is indicated.

at 25. The punch stands initially out of line. relatively to the inserting tool 10 andit describes the following motions :First an upward motion to punch a hole in the work conjointly with a punch-block 26, then a very slight downward motion suliicient to relieve the pressure against the punch-block,

then a lateral movement from rightto left to feed the work and to locate the clenching tool in coaXial relation to the inserting tool, then a slight upward movement at the instant of clenching, and finally a return movement to the position shown in Fig.- l.

The punch-block 26 is rigidly connected to a plunger 27 and the latter is arranged to slide up and down in a bearing 28 afforded bya horizontally adjustable guide This guideis arranged to slide on a fixed stud 30 projecting from a part of the machine frame. Although the plunger 27 is capable of being raised to facilitate the placing and the removal of the worlr it is sustained rigidly against the punching stress of the punch 16 when the machine is in operation, and at such times the lower face of the punch blcclr 26 is either in contact with the upper sur face of the work or. is so closeto the latter that there will not be any appreciable upward displacement of the work when the punch is functioning. The plunger 27 also carries apresser-foot 31 but the latter is movable relatively to the plunger and is normally depressed by a suitable spring (not shown) whereby downward pressure on the work is maintained continuously while the machine is feeding the work and setting the eyelets. i I j The extent to which the lower tool 15 is displaced laterally from the axis of the upper tool depends upon the length of feeding steps for which the work-feeding nieclianism is adjusted, and since the hereinafter described are illustrated in connection with a machine of known construction having a variable work-feeding mechanism,

the latter mechanism is illustrated herewith as a convenient means of showing how the gaging device may be incorporated lnto such machine so as to derive adjusting movement from the feed-changmg mechanism.

Referring to Fig. 4;, the feeding motion is taken from a horizontally movable slide 85 that has reciprocatory motion of con stant amplitudeimparted to it by means such as a cam, not shown. The motion of. the slide is transmitted through links 86 and 37 to an arm 38, the pivotal joint 39 by which the links are connected to each other being guided by a guiding link 40. Arm 38 is aiiixed to a rock-shaft all which has a bearing in the frame of the machine. An arm 42 is adjustably connected to the rock-shaft 4:1 and embraces a swiveled block 43 mounted on the feed-carriage 24. The amplitude of motion imparted to the feedcarriage is varied. by shifting the fulcrum pin as about which the guiding linlr {l0 swings. Thisfulcrum pin is carried by a regulating lever 45 that swine s about the axis of stud 46. The handle or the regulator 45 overlies a stationary plate 4'? in which holes 48 are formed for the reception of a other characteristic feature of the stop-pin 4L9. The handle is normally maintained against the stop-pin by a spring50.

Whenever the pin 49 is shifted from one foot whenever the feed-regulator shifted the mechanism includes suitable connections between the regulator and the slide 29. Still referring to Fig. fl, the regulator is provided with a cam-groove 51 which alters the positionof camroll 52carriedby a lever 53. This lever is mounted upon but is movable relatively to the rock-shaft e1. lhe forward arm of the lever is connected to the slide 29 by a suitable universal joint connection that need not be described since it is fully described in the aforesaid Glass application Serial No; 323,164. Thus, although the slide 29 doesnot move while the feed-carriage 2 is functioning it is shifted horizontallv whenever the feeoing mecha nism is altered to var the length of the feeding V steps, thereby maintaining the punch-block in the desired position for co; operating with the punch.

The gages by which the leading edge or located preliminarily to setting the machine in operationare indicated respectively at 55 and 56. Tie gage 55, according to tie present design, vis arranged to indicate the initial position of the lower edge of a left hand quarter, while gage 56 is arranged to indicate the initial position of the upper edge of a right-hand quarter. These gages as shown are adjustably connected to a bracket 57, the latter being provided with grooves 58 through which the shanks of the gages extend. A djusting screws 59 and 60 are rotativoly, mounted in the bracket asshown by 5 but they do not move longitudinally in relation to the bracket. The shanks of the gages are bored and tapped for the reception of the adjusting screws so that when each screw is rotated the corresponding gage will be shifted in lines substantially parallel to the direction in which the work is fed.

adjusting movement ofthe slide, the connection preferably providing for collective adjustment of the gages transversely of the lines of feeding motion. As shown, a pivot stud .61 forms the principal connection between the bracket and the slide while an adjusting screw 62'forms other connection. Screw 62 is mounted in ears 63 formed on the slide and althoughit iscapable of being rotated it has no longitudinal motion relatively to the slide. on the bracket 57 is provided with an in ternal screw-thread arranged to co-operate work 7 is Bracket 57 is connected to slide 29 so as to partake of An ear 64: formed with screw 62 although the threaded part of the ear does not entirely surround the screw. I a

Bracket 57 is preferably provided with an abutment 65 arranged to bear "against the longitudinal edge 66 of the workto determine the distance between that edge and the row of eyelets. this distance may be altered turning the screw 62 and it is also obvious that whenever such adjustment is made the gages 55 and 56 will partake of the adjusting movement and will therefore be'maintained always in j a predetermined relation tot-he edge 66 of the work. I

The bottom surfaces of the bracket 57,

work-guide 65, and gages 55, 56'ar'e" arranged to bearon the work-support QOand on a surface 67 of the machine-frame. The adjustable elements are thus amply supported without imposing too great strain on the connections between the bracket 57 and the slide 29.
