OF BOSTON, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 501,754, dated. July 18, 1893.

Application tiled Tune 6', 1892. Serial No. 435,678- (No model.)

To @ZZ whom it may concern:

Be it known that we, EEAsTUs WooDwARD, of Somerville, in the county of Middlesex and is a specification.

This invention relates to eyeleting machines of the type in which the material is punched for the reception of the eyelets, and

fed to produce the requisite spaces between the eyelets, the machine being provided with eyelet-inserting and attaching mechanism whereby, after each feeding of the work, an eyelet is inserted in the hole last punched.V

The invention has for its object to provide.

a machine of this class in which the'movements of the punch and die that form the eyelet-receiving holes, as well as the move- 'ments of the top and bottom sets which insert and secure the eyelets, shall be rectilinear instead of being in the arc of a circle as heretofore, so that the operation of said parts will be more accurate and reliable; secondly, to

enable the length of the feed movement ofl the material and the spacing of the eyelets to be readily and quickly varied, so that the machine may be readily changed from one spacing to another, and thus enabled to alternately attach eyelets and lacing studs, or to attach either eyelets or lacing studs at varyingdistances apart.

The invention also has for its object to:

provide improved mechanism for operating the punching and eyelet-setting devices.

To these ends, the invention consists in the severalimprovements which we will now pro constituting parts of our invention, being removed for the sake of clearness. Fig. 3

represents a front elevation of that portion of the machine comprising the punching and -the machine.

eyelet-setting devices and the parts that are directly connected therewith. -Fig. 4 represents a view similar to Fig. 2, showing a-dif ferent stage ot the operation. Fig. 5 represents a top view of the mechanism shown in Fig. 4. Fig. 6 represents an elevationof the opposite side of the machine from that shown in Fig. 2. Fig. 7 represents a top view of a portion ofthe machine, the 'eyelet reservoir and chute being removed. Fig. 8 represents a rear elevation of a portion of the machine, showing dierent means for changing the length of feed or the spacing of the eyelets. Fig. 9 represents a side elevation of the devices shown in Fig. 8. Figs. 10, 11, 12 and 13 represent perspective views of portions of Fig. 14 represents an enlarged section on the plane of rline 14'-14,'Fig. 1, showing the punching and eyelet-attaching devices.

The same letters and numerals ot' reference indicate the same parts in all the gures.

In the drawings: a, represents the supporting-frame, and b the drivingshaft journaled of an eyelet, and surrounded by an annular shoulder e', which upsets and forms the flange upon the end of the tube of the eyelet when said tube is pressed upwardly by the bottom set e2. Said bottom set is composed of a tube,

having its upper end provided with an annu-` lar concavity, as shown at e3 (Fig. 13), to sup-` port the flange formed at the lower end of an eyelet.

e4 represents the iin-ger, which enters the lower eyelet in the eyelet chute f, detaches said eyelet from said chute, and causes the engagement of the eyelet with the bottom set. Said finger is adapted to slide in the interior of the bottom set, and is supported by aspring f5, which permits the finger to yield when the bottom and top sets are brought together, as shown in Fig. 14. The punch d is located IOO ment being such that, after the work on the table chas been punched, the punch is moved laterally while in the work, and thus caused to feed the latter, the punch emerging from the work and leaving the punched hole in position to receive the eyelet, which is inserted and attached bythe conjoint operation of the top and bottom sets.

As shown in Figs. 12 and 13 the punch d is affixed to an arm d5, which is formed on and projects from a carrier d6, which is fitted to ends of which are suitably supported in sockets on the frame a. The punch-carrier d6 is adapted both to slide vertically and to oscillate horizontally upon the guide-rod d?, and mechanism is provided for giving said carrier the described movements, and thus causing both the vertical and lateral movements of the punch, which cause it to perforate and feed the work.

The top set 6 and its shoulder 6 are affixed to an arm 65, which is formed on and projects from a carrier 6, adapted to move vertically and swing horizontally upon a guide-rod 67, which is located beside the guide-rod all, the top set being given its lateral and vertical movements by the described movements of thev carrier 66.

The punch die d is affixed to an arm d8, whichA is formed on a carrier d, which is fitted to slide vertically and oscillate horizontally on the guide-rod C17, the die-carrier d1 being adapted to move vertically independently of the punch-carrier d6. The two carriers are engaged, however, so that they swing horizontally in unison, by means of an arm d10, afxed to the punch-carrier, and engaged at its outer end with a vertical guide du, affixed to the arm (Z8, the engagement of the arm d10 with the guide CX12 being such that the punch-carrier and the die-carrier can move vertically,

each independently of the other,but are caused to move horizontally in unison.

The bottom set is affixed to an arm 68, which is formed on a bottom set carrier 69, which is fitted to slide vertically and swing horizontally upon the guide-rod c7. The top and bottom set carriers are adapted to move independently of' each other, in a vertical direction, on said guide-rod; and are connected so that they necessarily swing horizontally in unison, by means of a guide-bar 610, affixed tothe top set carrier 66, and engaged with a grooved lug or ear 612, affixed to the bottom set arm 68, vthisengagement enabling the top and bottom sets to move vertically independently ot'y each other, and requiring them to move horizontally in unison.

y It will be seen from the foregoing that the punch and die and the top and bottom sets, in co-operating with each other, move rectilinearly in consequence of their being mounted on carriers which move on fixed guiderods. Hence there is no swinging movement of either of said parts .when it is approaching the co-operating part, and vthe two parts or members of each organization,-namely, the punching and the eyelet-setting organizations,--are positively guided and caused to co-operate with the utmost exactness.

We employ a mechanism for imparting the necessary vertical movements to the punching and setting devices, and another mechanism for imparting the horizontal swinging motions to said devices, and these mechanisms we will now describe, beginning with the mechanism for moving the punching and setting devices vertically.

g represents a stud, which is affixed tothe supporting-frame. On said stud are mounted to oscillate two levers, d13 613. These levers are oscillated vertically by means of eccentrics (114 611, on the driving-shaft b, and connecting-rods CZ15 615, which respectively connect the eccentrics C111 614 with the levers d 613. The swinging end of the lever (1.13 is engaged by meansA of a stud (116 with an ear on a yoke or frame d, which is provided at its upper and lower ends with lugs CX18 e119, fitted to slide upon the guide-rods d7 67. The lug C118 bears upon the upper end of the punchcarrier d6, and the lug (119 upon the lower end of said carrier; hence the verticalmovements of the yoke d cause corresponding movements of the punch-carrier and punch. The bottom set carrier 69 bears upon the lower lug d1, and is provided with an upwardlyprojecting extension 621, terminating in an ear or lug @20, which is fitted to slide upon the guide-rod 67, and bears upon the lug (11S. Hence the bottom set rises and falls in unison with the punch, the bottom set carrier and punch-carrier being similarly engaged with the yoke du, and reciprocated vertically thereby, the punch and bottom set having no vertical movement independently of each other.

The outer end of the lever 613 is engaged by means of a stud 616 with an ear on ayoke 617, provided at its ends with lugs 61S 619, which lugs are fitted to slide on the guiderods dl 61, the lugs 618 619 being located below the lugs d18 d1, as shown in Figs. 3 and, 13. The lug 618 bears on the upper end ofthe `top set carrier c6, and said carrier is provided with a downwardly-projecting extension 622 (Fig. 10), terminating at its lower end in an ear or lug 625, bearing upon the lower lug 619 of the yoke 617. The punch die carrier di is provided with a downwardly-projecting extension d21 (Fig. 11), having at its lower end an ear d20, fitted to slide upon the guide-rod d1, and bearing on the lower lug 611, ot' the yoke 617. It will be seen, therefore, that both the top set carrier and the punch die carrier are engaged with the top and bottom lugs of IIO l the yoke @17, so that they will be reciprocated vertically together, byV movements of .i said yoke, the said punch die and top set moving verticallyin unison, and having no vertical.

movement-independently of each other.

We will now describe the mechanism for moving theV punching and setting devices horizontally. y

h represents a horizontal lever, which is [itted to oscillate upon the guide-rod d7, and vis oscillated horizontally by means presently dev scribed. The forward end of the leverh is provided witha vertical slot or guide 71,2,-

downwardly from the punch die carrier dg,

said arm d24 being adapted to slide vertically while engaged with the lever h, so that the horizontal movements of said lever impart similar movements through the arm d2? to the punch die carrier,'and through the arm d10, having 4the described sliding connection with the punch diecarrier, to the punch-carrier d6. while movable vertically independently of each other, are caused to move horizontally in unison.

h3 (Figs. l and 5) represents a lever, which is fitted to oscillate horizontally upon the guide-rod e7, and is located beside the lever h, its swinging end being in close proximity to the end of the lever 71. that is engaged with the punch die carrier. The lever h3 has a lug or projection h-l (Fig. 5), which is arranged to strike a similar projection h5 on the lever h, the arrangement being such that, when the lever??l is moved in the direction indicated by the arrow in Fig. 5, its projection h5 will strike the projection h4 and move the lever h in the same direction. The lever h is provided at its forward end with a vertical guide h6 (Fig.f8),which receives anarm e124, projecting downwardly from the top set carrier e6.y It will be seen, therefore, that the movement of the lever h3, as indicated, will cause a corresponding movement of Athe bottom set, and,

through the described engagement of the bottom set carrier with the top set carrier, a similar movement of the top set. A spring h7, supported by a rod hpivoted at b9 to the lever h3, presses the lever h3 in the opposite direction, andpcauses it to follow the lever h when the latter is -moved in the direction opposite that indicated by the arrow in Fig. 5, the rod hs being adapted to slide in a guide in the supporting-frame.

The mechanism that oscillates the lever h to give the punching and feeding devices their lateral movements is as follows: 't' represents a horizontal rod, adapted to slide in guides in the supporting-frame. To said rod is affixed a collar having an ear 2, to which is pivoted at 3 a link or arm 4. The link ^1 has on its outer end a trundle-roll 5, which engages a cam 6 (Figs. 1 and et) on the shaft b. Said cam is formed to oscillate the link 't'4 .slide 'To in a slot 7 in the link 4.

Hence thepunch die and the punch,

horizontally onv its pivot 3. The lever h is provided with a slot or way hm. (Figs. 4 and 5), which receives a slide k12, from which projects upwardly a stud h, passing thro-ugh a The stud hr3 constitutes an adjustable` pivot, connecting the link 4 with the lever h, and enabling the oscillating movements of said link to-impart oscillating movements to the lever h,theY extent of which is determined by the position of the stud hm, said stud being movable toward and away fromv the pivot 3, on which the link 4 oscillates. Ve have provided means whereby the operator may. readily move the stud h13 back and forth between two positions, in one of whichl the stud is at its minimum distance from the pivot 3 and gives the lever 72, and the punching and eyelet-setting devices a minimum movement for short spacing, while in the other position the stud h13 is at its maximum distance from the pivot 3 and gives the lever hand the punching and eyelet-setting devices their maximum movevment for long spacing.

Ve have here shown, as the means for changing the position of the stud h13,thefol lowing mechanism:

j (Fig. 6) represents a disk, which is mounted to rotate upon a stud j', affixed to one side of the supporting-frame, and provided on its inner side with a cam-groove jz, shown in dotted lines in Fig. 6. l f

js represents a lever, pivoted at ji to the supporting-frame, and having at one end a trundle-roll j, engaging the cam-groove' j2. Near the other end of the lever js is an adjustable stud js, engaged with said lever, and adjustable lengthwise thereof. The stud j connects the lever js to an arm ,'7'7, affixed to the rock-shaft g hereinbefore referred to.- To-- said rock-shaft g is affixed an arm js, the lower en'd of which is connected by a link t7'9 with the stud 7113. To the disk j, having the @camgroove jz, is affixed a ratchet-wheel jw, having, in this instance, four (4) teeth, of equalflength. jm represents a pawl, pivoted to a lever t7'13, which is pivoted at jmto the su pporting-frame, and has one end connected by a rod L7'15 withV a treadle (not shown) under the machine. When the treadle andthe rod jl? are depressed by the operator, the pawlj12 is thrown upwardly, and caused to give the ratchetj10 and diskj a partial rotation. The cam-groove 7'2 is composed of two dead or concentric portions 2 2 of short radius, and -two dead or concentric portions 3 3 of longerradius, the intermediate portions of the groove being'eccentric or cam-shaped, all as shown by dotted lines in Fig. 6. l Y

jm represents Ia st ud or, wrist-pin, adj ustably secured to ak disk ju, affixed to the drivingshaft b. l

j represents a link, connecting the stud or wrist-pin jm with a Vpawl y19, having an arm j20, which is pivoted tothe link f8, the pa-wl being pivoted at jm to an arm j, adapted to-oscillate loosely on the stud j. -The pawl jl" is IIO arranged to engage the teeth of the ratchet jl", and give said ratchet and the disk j a partial rotation, when said pawl, in moving forward, engages a tooth of said ratchet, the pawl being regularly reciprocated by the rotation of the shaft b through the wrist-pin jl@ and link jls. rlhe arrangement is such-that, when the lever j13 is operated by the treadle, the pawl l7'12 will give the ratchet and the disk j a movement sufficient to bring one tooth of the ratchet jl@ into the path of movement of the pawl jl", so that said pawl, in moving forward, will give the ratchet jl@ and disk j an additional movement7 the two movements,- namely, that given by the pawl i7'12, and that given by the pawl j19,-bein g sufficient to move one of the dead portions of the cam-groove Y ,72 away from the trundle-roll j5, and the succeeding dead portion into engagement with said trundle-roll, so that, upon each movement of the lever f3, the trundle-roll will `be moved toward or from the axis of the disk j, as the case may be, the trundle-roll being moved away from said axis when the disk j is being moved from the position shown in Fig. 6, said movement carrying the trundleroll from one of the inner dead portions 2 to the succeeding outer dead portion 3. After the pawl j has partially rotated the disk 7', it is thrown out of engagement with the ratchet, and retracted by a suitable spring; and, after the pawlj19 has completed the movement of the disk j, there will be no further movement of said disk until the lever 3'15 is again operated by the treadle. of position of the disk j last described causes the intermediate devices to move the stud 71,13 i

to its outer position, and thus give the punching and eyelet-setting devices their maximum horizontal movement. The neXt operation of the lever j will partially rotate the disk j and cause the pawl ,719 to give the same another partial rotation, and thus move the cam groove, so that the trundle-roll will pass 4from one of the outer dead portions 3 to the succeeding inner dead portion 2, thus moving the stud his to its minimum throw position, and causing it to give the punching and eyelet-setting devices their minimum horizontal movement. It will be seen, therefore, that the operator, by simply depressing the treadle, causes the power of the machine to change the spacing or feed of the material from long to short, or from short to long.

To provide for an additional horizontal movement of the punching and eyelet-setting devices, in addition to that provided for by the mechanism above described, we give the ear i2, to which the link 4 is pivoted, a horizontal reciprocating motion,which takes place while the punch and top set are raised and the punch die and bottom set are depressed, and therefore while said parts are separated from the work, the object of this additional movement being to enable the spacing to be made as short as may be desired, without cutting away the adjacent surfaces of the arms The change 4 that carry the punching and eyelet-setting devices; or, in other words, to make the spaces between the eyelets shorter than the actual space between the punch and top set and punch die and bottom set, when said parts are at their closest approach.

Means for effecting the lateral movement of the ear i2, as here shown, are as follows: Said ear, as already stated, is affixed to the sleeve i', which in turn is affixed to the stud t', which is adapted to slide lengthwise in guides formed in the supporting-frame. The stud i is provided on its upper side with a trundle-roll t8 (Figs. 4, 5 and 8),which engages a cam-groove t9, formed in one arm of a lever @'10, which is pivoted at 7112 to the supportingframe. The other arm of said lever is connected by a link 7213 with an arm im, affixed to the lever Z13 above described. The oscillating movements of the lever (Z13 are imparted through the arm 14, link 13 and lever 19 to the cam-groove t9, which is formed to impart a reciprocating motion to the stud t', ear i2 and the pivot or fulcrum 3, said mechanism being timed to give the pivot 3 a short lateral or horizontal movement, and thus give thepunching and eyelet-setting devices additional horizontal movements when they are being moved horizontally by the mechanism above described. It will be seen that this additional lateral movement, taking place while the punch and top set are raised, enables the top set to retreat before the punch when the latter is moving, preparatory to punching and feeding the work, so that, after an eyelet has been inserted and the top and bottom sets have separated, the punch is enabled to move as far as may be desired toward the last hole before it punches the work, the top set retreating before the punch. Hence the holes can be made as close together as may be desired, without regard to the thickness of the arms which respectively carry the punch and top set and the punch die and bottom set.

In Figs. 8 and 9, We show a modification of the mechanism for changing the position of of the stud 7113 and varying the length of the spacing. In said modification, the diskj has a cam-groove t, formed as shown by dotted lines in Fig. 9, and the rock-shaft g has asingle arm 5,-having a trundle-roll 6 engaged with the cam-groove 4.v The disk j, in this case, is rotated by the hand of the operator, and is provided with a brake 7, held against its periphery by means of a spring 8, to prevent loose rotation of the disk, and retain it in any position to which it may be adjusted, the brake being a shoe, formed on a lever 9, pivoted at l0 to the supporting-frame. The form of the cam-groove 4 is such as to give the stud hw, through the arm 5, rock-shaft g and the devices already described connecting said rock-shaft to the stud hw, a series of positions; or, in other words, any position between that caused by the engagement of the trundle-roll 6 with the inner end of the camgroove, to that caused by the engagement ot' IIO said trundle-roll with the outer end of the cam-groove. The diskis provided with marks or gradations on its outer side, as shown .in Fig. 9, said marks registering successively with a mark l2 on the brake 7, and indicatlng the length 0f the spaces which would be produced by any given adjustment of the' disk t7. The operator is thus enabled to effect more than two variations of the spacing, as will be readily seen.

The machine is provided with a presser-foot le, and suitable means for raising and lower- 1ng the same, both automatically and by the act of the operator; but, as the presser-foot mechanism employed by us involves nothing new, we do not deem it necessary to describe the same.

The eyelet chutef is or may be oscillated laterally by means of a lever m, affixed to a vertical shaft m', which is journaled in bearings on the supporting-frame; a trundle-roll m2, on one end ot' said lever, engaged with a cam 'm3 (Fig. 7) on the disk j; an arm m4, on the shaft m', pivotally connected at m5 with the lower portion of the eyelet chute; and a spring msconnected at one end with the frame of the machine, and at the other end with one arm of the lever m, said spring acting to hold the trundle-roll m2 against the cam m3. The eyelet chute is mounted to oscillate upon a pivot f (Fig. l),and is provided at its upper end with the usual eyelet reservoir f2, containing a suitable agitator, which supplies the eyelets to the chute. When the disk j is adjusted to give the punching and setting mechanisms their minimumlateral movement, the cam m3 is out of contact with the trundleroll m2, and therefore does not act on the leagainst the cam m3.

ver m. Under these circumstance, the lever 'mis oscillated at regular intervals, by means of a cam m7 on the disk j, said disk being continuously rotated by the driving-shaft b, the spring m6 holding the trundle-roll m2 The oscillating movements imparted to the eyelet chute by the cam m7 and spring m6 cause the lower end of the eyelet' chute to stand in the path of the bottom set when the latter is rising, and until the bottom set has engaged the lower eyelet in the chute, the chute being then moved laterally out of the way of the bottom set, as usual in eyeleting machines of this class. When the disk j is adjusted to give the punching and eyelet-setting devices their maximum throw, the cam m5 is brought to bear upon the trundle-roll m2, and moves the lever m in such manner as to displace the lower end ot' the eyelet chute from its operative position, andprevent the supply of eyelets to the bottom set so long as the last mentioned adjustment continues. It will be seen, therefore,

that the supply of eyelets is automatically stopped whenever the lateral throw of the punching and eyelet-setting devices is increased. The object of preventing the supply of eyelets, as last described, is tov enable holes to be punched andthe work to be fed wi-thout inserting anything in the holes, the holes being subsequently supplied with lacing hooks, by other means. Heretofore, in machines `in which the spacing is variable, the supply of eyelets has been'prevented by means which are dependent for their operation upon the act of the operator. Hence there has always been liability of supplying eyelets to the holes intended to receive lacing studs, through carelessness of the operator. lt will be seen that, by automatically preventing the supply of eyelets, as described, the liabilityT of inserting eyelets in the holes intended for lacing studs is prevented.

The operation of the machine is as follows: Then the punch d descends to penetrate` the work, the punch die d rises, to co-operate therewith, as shown in Fig. 3, the top and buottom sets being at the same time separated. After the punch enters the work, it moves laterally toward the left, as viewed in Fig. 3,

thus feeding the work the required distance,

which is determined by the adjustment of the stud 7113. The punch and die then separate, and at the same time the punch and die and top and bottom sets are moved laterally toward the right as viewed in Fig. 3, until the top and bottom sets are in line with the punched hole. The lateral motion then ceases, and the bottom set raises its nger, picking an eyelet from the lower end of the chute, and carrying the yeyelet up into the work, and co-operating with the top set in upsetting and attaching the eyelet. The top and bottom sets then separate, and `the punch and die are moved laterally toward the left, the top and bottom sets retreating at the vsame time, until the punch reachesthe desired position to form the next hole, when it descends and forms another hole, and ,so on, the operation being' repeated indefinitely. It will be seen that the pair of devices which punch the material,-namely, the punch and die,-are supported by a pair of carriers, each movable vertically independently of the other to permit the punch and die to alternately approach and recede from each other, Vand each having a sliding connection with the other, so that the punch and die are always kept in alignment, and are caused' to move laterally invunison. The same statement is true of the pair of setting devices comprising the top set and the bottom set, these devices being supported by a pair of carriers, which are movable vertically independently of each other, and are connected by a sliding 'connection, so that the setting devices are always kept in alignment with each other and caused to move laterally in unison; This sliding'connection between the carriers of each pairis a veryimportant feature ot ourinve'ntion,`since it entirely precludes the possibility of the punch and die and the top and bottom sets being thrown out of alignment with each other by carelessness of the` operator in adjusting the machine.` -We do'not'limit ourselves to the detailsof IOO IIO

mechanism hereinbefore described, and may secure the more important results which we have mentioned, by any other suitable mechanical contrivances, said results being the keeping of the carriers of each pair in alignment with each other, the changing of the lateral movement of the punching and set-v jm, the pawl t7'19 which is continuously oscillated by the power of the machine, and the connections between the cam-groove in said disk and the adjusting stud 71,13, constitute a normally inoperativemechanism for moving the stud h13 from either of its operative positions to the other by the power of the machine, said mechanism being made operative by devices controlled by the operator, and

comprising, in this case, the leverj, and the pawlj12 adapted to be moved by said lever to give the ratchet ,7'10 a partial movement, and put it into position to be additionally operated by the pawl jm. It will be further observed that the movement of the disk j, which carries the trundle-roll j, from one concentric portion of the cam-groove ,i2 to another, through the intermediate eccentric portion, is effected by the power of the machine and that the movement ot' the disk j which is effected by the operator through the lever jm is accomplished entirely while the trundle-roll j is engaged with one of the dead or concentric portions of the cam-groove, and prepares the succeeding eccentric portion of the cam-groove to act on the trundle roll. Hence all the movements of the disk j that require considerable application of power are effected by the-.power of the machine, and no change in the length of spacing is possible until the operator prepares for said change by giving the diskj a partial rotation.

In an eyeleting machine, the combination of a pai]- of punching devices, a pair of eyelet-setting devices, two pairs of carriers supporting said devices and adapted to swing laterally, mechanism for reciprocating said carriers vertically to cause the devices of each pair to alternately approach and recede from each other, mechanism including two levers and an adjustable connecting stud or pivot, whereby the carriers are moved laterally, a laterally movable eyelet chute adapted to supply eyelets to the setting devices, mechanismsubstantially as described for adjusting the position of said stud to vary the lateral movement of the punching and setting devices, and mechanism substantially as described for displacing the eyelet chute from its operative position when the lateral movement of the punching and setting devices is increased, as set forth.

7. In an eyeletin g machine, the combination of a pair of punching devices, a pair of eyelet-setting devices, two pairs of carriers supporting said devices and adapted to swing laterally, mechanism for reciprocating said carriers vertically, adjustable mechanism whereby the carriers may be moved back and forth laterally, said mechanism including an adjusting device whereby the lateral movement of the carriers may be made longer or shorter, normally inoperative mechanism substantially as described for moving said adjusting device from either of its operative positions to the other by the-power of the machine, and devices substantially as described controlled by the operator whereby said normally inoperative mechanism may be made operative to change the length of said lateral movement, the said mechanism being organized to become inoperative after effecting each change, as set forth.

8. In an eyeleting machine, the combination of a pair of punching devices, a pair ofeyelet-setting devices, two pairs of carriers supporting said devices and adapted to swing laterally, mechanism for reciprocating said carriers vertically, adjustable mechanism whereby the carriers may be moved back and forth laterally, said mechanism including an adjusting device whereby the lateral movement of the carriers may be made longer or shorter, normally inoperative mechanism forl eral movement of the punching and setting devices is increased, and devices controlled by the operator whereby said normally inoperative mechanism may be made operative to change the length of the said lateral movement, the said mechanism being organized to become inoperative after elfecting each change, as set forth.

9. In an eyeleting machine, the combination of a pair of punching devices, a pair of eyelet-setting devices, two pairs ofl carriers supporting said devices and adapted to swing laterally, mechanism for reciprocatingsaid carriers vertically, adjustableV mechanism whereby the carriers may be given a longer or a shorter lateral movement, said adjustable mechanism including an adjustable studl which determines the extent of said lateral movement, a laterally movable eyelet-chutev arranged to supply eyelets to the settingdevices, a rotary disk having a cam-groove such as ,7'2 and a cam such as m3, connections between said cam-groove and the-movementcontrolling stud whereby said stud is moved by changes in the position of the disk, connections between -the cam m3 and the eyelet chute whereby the chute is displaced when the disk is moved to position to increase the' lateral movement of the punching and setting devices, an operating device such as the pawl j operated by the power of the machine and adapted to give said disk a partial rotation,-V

and a device controlled by the operator for giving said disk a preliminary partial rotation and thereby enabling said operatingl de vice to give the disk its-space-chan ging movement, as set forth.
