'To all; wliom 'it may concern: y

B'e' it known that I, GEORGE GODDU, a citizen of the UnitedStates, residing at Winchester, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain improvements in Eyeleting Machines, 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 eyeleting machines and pertains more particularly to the type ot machine known as the duplex eyeleting machine in which opposite sides of a shoenpper are operated upon simultaneously.

in setting eyeletsin shoe uppers it is usually the practice to s et the lower eyelet onf each reater spread" than t at is, at asomewhat the edge of the lacingthereatteruthe rea lesser distance In the machine disclosed -in a 4co-pending application for Letters Patent of the United States, Serial No. 153,822, iiled April 22, 1903, means are provided whereby the operator may manually cause a spread of the lowest eyelets greater than that of the succeeding ones. The upper is so presented to the machine that the eyelets at the bottom of the lacing-slit then the rest follow up the slit. In the lmachine of said application when it is desired to set eyelets with a greater spread for the lowest eyelets, it is necessary for the operator to pull a lever before inserting each shoe-upper inthe machine.l This requires. the constant attention of the operator lsince it he fails toA pull the lever at the proper time, the first eyelet in each flap is not` set at the desired distance from the edge ot the lacing-slit. i

One of the objects oi' this invention ,theretoreis to provide automatic means whereby the lowest eyelets will be set with a spread greater than that of the'succeeding eyelets.

One embodiment of this invention' may be applied advantageously to an eyeleting machine which has a guide-plate and sprin presser-feet on opposite sides thereof to hold the two iiaps of a shoe-upper in proper engagement with said guide-post. Such a machine' -is disclosed in a co-pendln application for Letters Patent of the Unite States, Se-

tlap with a somewhat the succeeding ones,

greater distance from slity than the others, and maining eyelets are set at l rial No. 329,722, filed August' s, rete., in l the machine of l plate and the edge-gages secured-thereto are' moved .in unison by the operator before he' inserts the work in the machine.

The present invention contemplates the' provision of means for moving the edge-gages automatically to vary the distance at which the eyelets will be set from the edge of the lacing-slit and in its broad aspect it is immaterial Whether a guide-plate be movedat the same time or not.

In the preferred embodiment ot this invention a slidabl'e guide-plate having edge-gages secured thereto is held normally in rearward.l position relatively to an anvillate. in this position it is evident t at the shoeupper which is in contact with said edgegages will have its edges ositioned rearwardly relatively to the anvil-plate and that the eyelets which are set at this time will be somewhat remote from the edge ot the lacingslit. After the irst eyelet in eachiiap has been set the iride-plate and edge-gages carrying with tiem the shoe-upper are automatically moved forwardly tov decrease the spread ot the eyelets. The said arts are held in this forward position nnti the rest of the eyelets have been set.`l Upon the removal of the shoe-upper the guide-plate and the edge-gages are released and return to initial position. ing the guide-plateand attachededge-gages in their forward position to be released when the stockis removed is as followsz-A ratchet which is secured to Va stationary partl of the machine is arra ed to cooperate with a pawl carried by the sidable guide-plate. This pawl is so connected with relation to the spring presser-foot that when no stock is inserted etween the guideplate and .presser-foot,'said paWl 'will be out of engagement with the ratchet. When, however, the presser-foot is held away.

` the paw] engages the forwardly inclined teeth of the ratchet and retains the guidel plate and edge-gages in the forward position to which they are moved after the setting of the4 first eyelets, until the stocklis remove i A convenient arrangement for thus .controlling the pawl by means ot the spri v presserl toot consists in connecting the two y means i of a lever which holds the pawl out oi' engagei ment with the ratchet when the presser-foot said application the guide' A convenient means for hold-Q slightly from the guide-plate by the stock,-

VVhen, however', the presser-foot is thus moved, 'the lever is moved out of operative relation with the pawl and a spring is allowed to force the pawl into contact withv the ratchet. Means may be provided to prevent the backward movement of the guide-plate and edge-gages in be desired to set all of the eyelets with the same uniform spread.

Referring to the accompanying drawings, which illustrate one embodiment, of the invention-Figure 1 'is a top plan view showing the means for automatically varying the spread of the' eyelets and the parts immediately associated with said means; Fig. 2 is a view in side elevation of a portion of the device; Fig. 3 is a fragmentary sectional view on the line 1f-a, Fig. 1, showing a device to llock the edge-gages in position to renderv4 the spread constant; Fig. 4 is a fragmentary. sectional'view on the line Zi-b, Fig. 1, showing a device for adjusting the amount'of variation in the spread; Fig. 5 is a view similar to Fig. 1, showing the parts in the position which they assume after the first eyelet has been set and the stock' has been fed Fig. 6 is arts in the position which they assume a'ter the justing `device in posiv on the punching-blocks 10 lthe lever 6 is stock has been inserted; Fig. lar to Fig. 3 showing the locking device turned'into disengaged position,y and Fig. 8 is a view similar to Fig. 4 showing the ad- 'o`n` for making. a change in the adjustment.

A. feed-frame 1 which carries anA anvilplate 2 is pivotally'supported on a stud 4 carried by an elbow-lever' 6 which is pivoted at 8. The anvil-plate is provided preferably' on two oppositev sides with punching-blocks 10 and setting-dies 12. The arrangement is such that after the stock has ybeen punched 7 is a view simirocked so as to move the anvil-plate rearwardly and bring the setting-dies 12 into the position previously occupied by the punchlng-blocks as shown in'Fig. 1. The feedframe 1 is connected by means of links 14 and 16 to a lever 18 which is pivoted at 20. At the pivotal point 21 of the links 14 and 16 is pivoted a link 22 which in turn is pivoted at 24 to a fixed portion of the frame. The lever 18 is also connected by links 26 and 28 to a stud 30. This stud is clamped firmly to the link 28 b a binding-'screw 32 and extends a short istance upwardly from said link. To the upper end of thestud a plate 34 is secured'above which is a finger 36 on the stud 30, and rotatable 4thereon'for adjustment when the pin now to be described is retracted. One end of this finger has a casing 38 within which is mounted a springpressed in 40 having a head 42, the point of the pin eing normally urged downwardly so as to be engaged in any one of a series of in the plate 34. The iinger is thus v adjustably mounted relatively to the plate. l The othergend ofthe linger has a reduced portion 46 for engaging a lug 48 on a guideplate 49. Upon this' guide-plate' is a block 50 extending around tnree sides thereof but secured' thereto by a screw 52. On opposite 'sides of the-guide-plate, presser-feet 54 are secured to the block 50 by leaf-springs 56 which extend between pins 58 on the presser-feet for retaining the llatter in aline- `ment with said springs. The forward end of the block surrounds the guide-plate and forms edge-gages 60 to determine the position of the stock. The guide-plate is preferably formed with ridges 61 adjacent to the edge-gages to assist in keeping the stock in contact therewith. The guide-plate is slidably secured to a plate 62 having a fixed position on the machine, this movement being permitted by securing it by means of bolts passing through the slot 64 in the shank of the guide-plate and holes 66 in the plate 62. It will thus be seen that the guide-plate unless restrained is free to slide back and forth into the two extreme positions shown in Figs. land 5 although normally drawn into rear- -ward position in the manner now to be described. The extreme rear end 67 of the guide-plate is connected by a spring 68 to a iiXed part ofthe machine and therefore the guide-plate carrying with it the edge-gages 60 is pulled in the direction o f'the arrow z and assumes the position shown in Fig. 1 except when held out of this position against the tension of the spring 68 by the means now to be described. A

The plate 62 has an integral .extension provided with a ratchet 70 whose teeth are lnclined forwardly as shown in Figs. 2 and 6. A pawl 72 is pivoted on a pin 74 extending between lugs 76 on the block 50. The pawl is held by the means now to be described in the position shown in Fig. 2 so that it is out of engagement with the ratchet when no stock is inserted. Pivoted on the pin 74 independently of the pawl is a lever which at l holes 44 bending over the endx of the leaf-spring whic carries the presser-foot. ries a` pin ,84 projecting laterally on both sides thereof. Upon one side said pin serves as a means for securing one end oa spring 78 While upon the other side said pin overlies the upper surface of the lever 80 at the end of said lever opposite that engaged by the lip 82. The lever 80 'therefore is so arranged that it holds the pawl 72 out of engagement` with the ratchet 70 against the tension ofthe p spring 78, as shown in Fig. 2, when no stock is inserted. When, however, stock is inserted, as shown in Fig. 6, the spring presserfoot 54 is raised the lever 86 is rocked, thus lowering the end which is engaged by the pin 84 and permitting thespring 78 to force the The pawl 72 carone'end is engaged by` a lip 82 formed by 'that the plunger is its end or pawllike portion 92 in engagement with the teeth 86, and the guide-plate 49 is ara-,eee

and' 16 the anvil-plate 2 isf turned on. itspivot 4y 'tomove the setting-dies 12 the distance between successive eyelets, and these dies being still-in -engagement with the stock, feed the same the required distance. At the samev time the links 26 and 28' are moved into the position-shown in Fig'. 5 .and the stud 30, secured to the linkA 28, is partially rotated. The' plate 34 and finger 36 are turned and the end of the linger by engaging withthe lug/18 forces the guideplate in the direction of the arrow yto its forward position.

Since the teeth on the stationary. ratchet.

70 are inclined forwardly the pawl 72 moves thereover and-when'the guide-plate has .been

moved into its forward position it is held there'fby the engagement of the pawl with the teeth until-the remaining eyelets have been set inthe shoe upper and the latter has been removed. Upon removal of the upper, the ypresser-foot 54, lever. 80 and pawl' 72 again assume the position shown in Fig. 2 and t e spring 68 draws the guide-plate 49 and atached edge-gages to rearward position to give the desired spread to the iirst edgefgageshave eyelet on/the next shoe-upper.-

It is sometimesfdesirable to dispense with the spread the eyelets at4 the vsame distance from the edge of the shoe-upper. The following device is provided for this purpose. Upon the guideplate 49 is a ratchet having rearwardly inclined teeth. 86 while u on the stationary plate y62 is mounted a casing 88 carrying a spring-pressed plunger 90. The end of this plunger is made in the form of a ratchet 92.

"l`he plunger isprovided with a head 94'and a pin 96, the latter'being adapted to it into a notch 98 i the casing. With the parts in the position shown in Fi 3 it will be seen held in position to have therefore held in forward position a ainst 'the tension of the spring' 68 and any c ange in the spread of the eyelets thus prevented. When,- however, the plunger is drawn backward and turned so that the pin 96 -is prevented 'rom enterin the notch 98, as shown in Fig. 7, the sprea of the eyelets is-varied as reviously stated.' 1

t will be'noted that the edge-gages 60 are inclined at an angle on the side from A clined edges of the gages the of the iirst eyelet' and 'set all of opposite which the vstock is fed.- By. presentingfthe stockto the machine with its'edgesparallel-to the inldistance of the holespunched in the stock and of the eyelets set therein Yfrom the edges of the stock is diminished while by turning-thestockfinto the position shown in Fig: 1 this 'distance may be.increased; This feature constitutes no part of the present. invention, but in connection. with the means for. automatically varying the position of the edge-gagesaffordsa convenient means for varying the position of the irst: fewi eyelets set m the bottom of the flaps .of lthe shoe-upper.

The operation of the machine willbe understood readily jromthe foregoing description. The operator inserts thetwo 'flaps ofi the shoe-upper between the guide-plate andv the two presser-feet respectively and starts` the machine. The punches come in contact with thepunching-blocks` 10 'from opposite sides and ahole is puncheddnthelowenportion of eac-h i'lap.- The lover 6 isthen vactuated and thefanvil-plate 24 is'-moved'rearwardly to bring the settin -dies 12 into the'- position previously occupie :bythe punchingblocks. Setting devices then fcoperate with 'the setting-dies 12 to: setthefiirst eyelets. The edge-gav es during` this time occupy theirrearwariposition and the 'lrsteyeletin each fla A.is Vsetst )mewhat remote frornthe. edges o' the lacing-slit.' `The lever 18. then movesin the directiomof the arrowa, Fig; 5,

to eedvthe work one spaceand to move the guide-plate 'forward inthe direction off the arrow y. The anvil-plate then returns to initial. or punching position and since the been moved forwardly relatively to the anvil-plate itis evident that the holes will now be punched nearer to the lacing-slit than before. The remaining eyelets in the series are thenfset consecutively' and upon removal of'the shoe-upper from the machine the guide-plate and edge-gages' are returned automatically to .initial position, whereupon the cycle-ot operationswmay. be repeated.
