EYELETIN Gir-MACHINE.

Application filed October 25, 1913, Serial No. 797,225. Renewed December 3, 1914. Serial No. 875,386.

called gang eyeleters which insert andl clench a series of eyelets at each operation of the machine without feeding the material; and single and duplex eyeleters which insert and clench onlyT a single eyelet or a pair of eyelets at once and feed the material step by step to position it for lthe successive eyelets. The former of these classes of machines is of very limited utility for the reason that the line or series of punches and sets in the machine being of course formed and arranged for a particular size and shape of shoes, are hence adapted for only one shape of material7 and thus a diiferent shaped line and arrangement of punches and sets would have to be provided for each of the many different shapes and sizes of shoes. 'Ihe latter of the above classes of machine on the other hand is adapted to produce any desired form of eyelet line hymerely varying the direction of material feed or the spacing of same, or both and is therefore the one in general use, and in this type of machine it will be understood that as the material is intermittently fed step by` step between the punching and setting operations, to space and position the same correctly for the succession of eyelets, it is necessary to provide means whereby after the hole is punched in the stock and the stock fed,v it be accurately spaced and alined with the eyelet also precisely positioned. for the ac-' `tion of the setting tool to clench the eyelet in the hole. To attain this end in all machines of the prior art known to me it has been considered necessary to employ devices actuated from both sides of the material. In other words, the holes are punched by a punch actuated from above the material and its support, While the eyelets are inserted and clenched therein, by a spindle and set, actuated from below the material. This spindle-and-set mechanism arranged op- Patented Aug. 14, 1917.

posite the punch with provision for automatic actuation at intervals up into operative position and then back out of the Way in proper sequence and timed relation to the other parts, along with provision for auto`- matic step by step feed of the material has made the machine a very complicated and expensive one with a multitude of parts apt to get out of order and relatively limited as to capacity even when Working at best. It is to be understood where the expression machines of this class or similar language is used herein that it refers generally to the second named type of machine, viz: where single or duplex eyeleting is performed with a step by step feeding of fthe material'for spacing the veyelets as distinguished fromv side of, e. g., above, the material support, thev material being fed step by step for spacing the same for successivey eyelets and being accurately positioned in alinement with the setting tool by a novel combination and operative arrangement of the punch and -set themselves without requiring any other ac-4 tive instrumentalities.

According to my invention there is no device below the material or opposite the punch that in the least cooperates with the punch and set, in the eyeleting 0f amaterial except a punch-block, and an eyelet clencliing surface, which co-act with said actuated punch and set in eyeleting a material byl their resistance only. I believe this to be the first machine of this class that does not c0ntain said spindle-and-set, and means by which they are actuated from beneath the machine. A prime object of' my invention is to abolish the spindle-and-set mechanism by providing means consisting in a punch and set operatively combined and actuated Wholly from one side of the material to do all the active work of a machine of this class, viz: eyeleting a material, feeding the material and spacing the eyelets. In a preferred embodiment I telescopically combine the set and punch by slidably fitting the punch within the set with provision whereby it may occupy a relatively telescoped position within the set while the set operates, while being held relatively advanced for punching the material and for engaging the same to feed it laterally. In accordance with my invention the punch, and preferably the set within which it is slidably fitted, are mounted for periodic lateral movement while the punch is engaged through the material, to feed the same laterally forspacing the eyelets, along with separatey punching and setting impulses which are imparted to the punch andset respectively at the proper intervals. KBy virtue of this arrangement it willbel seen that since the punch is itself the material feeding and spacing instrumentality, and since it is telescopically combined with the set, the material as fed by the punch engaging through the eyelet receiving hole is certain to be precisely and accurately positioned for the action of the setting tool when it descends to clench the eyelet. Thus considered from one aspect, by virtue of my improved arrangement the punch combines in itself, the threefold functions of punching the eyelet receiving holes, feeding the material, and serving instead of the separate underneath spindles heretofore employed for accurately-positioning and alining the eyelet in the punched hole for the setting operation. My invention therefore requires a material support equipped with a punchblock and a clenching surface or their equivalents, in combination with a punch and set operatively mounted on the same side of the material to act on the material on said support for punching the same and setting the eyelets inserted in the punched holes, with provision for feeding the material and spacing the eyelets which may be by the action of said punch alone, the operative parts acting` wholly from one side of the material to do all the active work of eyeleting the material, feeding the material and spacing the eyelets yby co-acting with the punch-block and clenching surface `below the material. This central feature of my invention, by avoiding the former spindle and set mechanism not only makes the machine vastly simpler .to construct, reducing the cost of machines of this class over seventy per cent., but also makes the machine more precise and accurate in operation and less apt to get out of order. I consider this combination to be broadly new and I desire the present embodiment to be considered as illustrative and in no wise restrictive, referring rather to the broader ones of the appended claims to indicate the scope of the invention. The invention will be better understood from the following detailed description in connection with the accompanying drawings wherein a single eyeleter is selected for exhibition.

Referring` to the drawings, wherein like reference numerals indicate the same parts on each of the several views,

Figure 1 is a side elevation of the machine;

Fig. 2 is a plan thereof;

Fig. 3 is a sectional view of the telescopic punch and the set combined, showing also the end of the operating lever in section and also a sectional detail of the clenching surface; and

Fig. 4 is a part sectional view of a punchblock whereon the clenching surface is also formed showing means whereby it may be adjusted relatively to the punch and set.

rllhe operating shaft 1 is suitably journaled at one end of the base of the machine and it has fixed thereto a peripheral cam 2, and a lateral cam 3 for effecting the working movements. A punch and set carrying lever is indicated at 4 with a ball shaped inner end 5 engageable with both of the cams 2 and 8 for periodic movement in both vertical and horizontal planes as hereinafter' described. To permit these movements the lever is pivoted on an intermediate horizontal axis 24;, the journal bearing of which is itself carried on a vertical axis 25 mounted to turn in a post upstanding from the frame work, there being a nut 26 holding the parts assembled. The outer portion of the lever is pressed upon b-y a spring 27 fixed tothe frame work to hold the ball 5 against the peripheral cam surface, and a tension coil spring 29 engages the outer portion of the lever laterally, tending to hold the ball against the lateral cam surface 3, thisspring being adjustable as to tension by a usual nut and bolt device. The outer end of lever 4 has fitted therein a set 6, the set being shown as threaded into the lever end for adjustment toward and from the clenching surface, with a lock nut `19 to hold the same securely in adjusted position. The upper end of the set- 6 is shown as terminating short of the topof lever f1 to permit the requisite range of adjustment without coming above the top of the lever to vinterfere with the punch head to be nowkdescribed. The punch 7 is shown as a tubular one slidably fitted concentrically in the set A6 to telescope therewith. The punch has an enlarged head at its top adapted to rest on the top of the lever when the punch is projected downward into punching position as seen in Figs. 1 and 3, and it is normally held in this position by a tension spring 31 having its respective ends engaged with the punch head and with the side of the lever. The punch-block is indicated at 8 fitted to a base 29, this block having a smooth face portion against which the punch 7 is adapted to act for punching the eyelet holes, and a clenching surface 11 also imperforate, including an annular concave recess, this clenching surface being in the present einbodiinent spaced apart some little distance from the aoition of the punch-block surface whereon t ie punch 7 acts. The present invention does not concern itself with any particular mechanism for supplying the eyelets, and for illustrative purposes I show in dotted lines a known form of delivery chute adapted to deliver an eyeletV 9 to position where it is taken up by the descending punch to be pressed at the proper instant into the punched hole. The material is indicated at 10 resting on the punch-block and material support constituted by the face of the base 29 with a spring 29 carried by the base serving as a presser foot to yieldingly hold the lever against the support with a capacity for lateral shifting tov space the eyelets; it will be understood that the spring 29 is merely illustrative to typify any suitable presser foot device to hold the material properly in place against the support.

The punch 7 is held in its advanced or projected position as seen in Fig. 1 not only by the spring 31 but also normally by a latch 13 pivoted at 14 to the lever 4 and held engaged over the head of the punch 7 by a spring 16 fixed to the end of said latch and movably engaged in a post 17 fixed on the lever, the action of said spring tending to move the inner end of the latch against a stop pin 18, in which position the outer end of the latch is over the punch. The-punch 7 in this advanced position is moved to punch the hole by coming against the punch block through the action of a portion 2EL of peripheral cam 2 as it is turned in the direction of the arrow in Fig. 1. Thereupon as the cam moves farther a slightly receding portion 2b permits the punch to move back a very little from the punch-block just enough to clear the same, the movement not being enough to move the end of the punch out of the material. lVhile this peripheral cam portion 2b is thus acting on the punch it is shifted laterally, by the action of a raised portion 3b of the lateral cam 3 which follows a lower portion 3a of said cam in the rotation thereof, the lever 4 then turning on vertical axis 25. Since the punch is still engaged through or in the material,

the material is of course moved alongwith.

tance is provided for by an adjustable stop screw 30 mounted in the frame worlqwhich engaging the side of the outer portion of lever 4 determines the position to which it 'tion 3a is opposite the ball 5;

may be moved by the spring 28 for the punching movement, 1l. e., when the cam porthis thus varying the initial lateral position of the punch and therefore its extent of movement. In the described swinging of lever 4 on its vertical yaxis to move the punch laterally, a pin 12 projecting from latch 13 comes against an adjustable stop piece 15 fixed to the frame work whereby the further movement of the lever causes said latch Vto be swung so that its outer end uncovers the punch head, whereby the punch is no longer positively locked in advanced position but only yieldingly held advanced by the spring 31. `With the parts in this position a further raised portion 2C of cam 2 comes into action on the ball 5 moving the outer end of lever 4 farther down so that the set 6 acts to press upon theeyelet as positioned in the punched hole. The clenching surface 11 is so disposed that it is at this time directly beneath the eyelet so that the eyelet isy properly and effectively clenched by the action of the set thereagainst. The punch 7 in this operation yieldingly recedes or telescopes within the set 6 and it is to be especially noted that it still presses, though yieldingly into the eyelet hole positively insuring absolute alinenicnt and accuracy of the setting tool in its action on the eyelet, since it will be observed the punch at no time leaves the hole which it has punched until the set is in full operation. Thus my present improved construction is very much simplified by reason of the fact that the punch serves not only to punch the holes and feed thestock laterally, but also to engage the eyelet eliminating the need of a separate spindle fitted in the set for coperation in 'the setting operation along with all the attendant mechanism required for moving said spindle at the proper intervals into and out of operative position, and also dispensing with the need of any separate mechanism for feeding and spacing the material; not only is the machine thus very greatly simplified in this way, but as will be apparent the cooperation of `parts is i'endered much more certainly precise and accurate since instead of being a case where a spindle for cooperation with the set has to be moved up to an eyelet hole which has been formed and positioned by other parts' of the mechanism, it is to be observed that with the present construction, the punch serving in a sense the positioning function of the spindle heretofore used, does this merely as a continuation of its preceding functionswherein it was positioned in the veyelet hole so thatV there is absolutely no chance for the set to act in any way except precisely concentric with the punch and therefore with the eyelet. It will'be understood that the foregoing is a point of special significance iii the feeding and spacing type of machine in distinction iio izo Y from the eyeleter type wherein since there isy no feed and spacing, there is no tendency for the eyelet as placed in the material to get out of alinement with the set before it operates. Referring further to the cams 2 and 3 it will be observed that the raised portion 3b of cam 3 continues on an even plane past that part of shaft movement where the final raised or setting portion 2C of the peripheral cam 2 acts, and then drops off as indicated at 3C to permit return of the lever 4L to re-position the punch at the punching station; also that the cam 2 directly beyond the setting raise 2c drops off to the lowest portion 2a where the lever t will be raised by the spring 27 to lift the punch and set for the next operation. lt is desirable to provide means whereby the punch-block may be adjusted toward and from the punch and set within small limits and for this purpose I mount the block S on screws 20,21, and form the lower surface of this block with wedge faces 8 adapted to be engaged by corresponding` faces on a wedge plate 23 which is adapted to be set up by a screw 22. Thus by loosening or tightening the screws 20, 21 in connection with a corresponding adjustment of screw 22 the punch-block S may be set firmly in the required position of adjustment. The adjustment of the punch-block thus provided permits it to be adjusted to a nicety so that the punch in its punching movement will press against the punch-block with a biting action on the material,` while this adjustment in connection with the adjustment of the set 6 by its screw threaded engagement in the lever Il, permits the relative adjustment of the set and punchblock for the best action on the various dif` ferent sizes of eyelets and thicknesses of leather.

In addition to the described advantages of the present organization in the way of simplicity and precision of action as compared with the separate spindle type of machine, it is to be pointed out that while having these utilities in a single machine as shown in the drawings, it has another and equally marked advantage in connection with a dupleX machine, since all the operating instrumentalities for setting a line of eyelets are at one side of the material and merely require duplication for setting a similar mating line and without involving any complex problem as to the disposition of working parts as is the case where a separate spindle working in the set from the other side of the material is required. It will of course be understood that when the punch is returned over the punching station in the cycle of movement, the spring 31 will again move it outward to punching position, and the latch 13 will move back thereover under the action of spring 16 thus completing the cycle of movement, While I preferably connected with a manual controlling arm l 35 as is usual in this type of machine; being what is known as a Horton clutch. It is to be observed that by the provision of screw 30 which as described determines the distance the eyelets are spaced apart, the machine is adapted to set eyelets spaced in any required manner and in any required line determined by the feeding.

Vhile in the more comprehensive embodiment of the invention as herein set forth, the punch 7 as noted combines in itself the three-fold functions of punching the eyelet receiving holes, feeding the material, and serving instead of a separate spindle to accurately position and aline the eyelet in the punched hole for the setting operation, it is to be understood that certain modifications of this arrangement are within the scope of the invention in its broader aspects. For example, the punch telescopically combined with the set as disclosed is valuable and useful in conjunction with a feeding and spacing means of any kind so long as the arrangement is such that the punch first acts to produce the eyelet receiving hole, and then serves as a positioning spindle to properly position the eyelet in such hole, this permitting all the working parts to be disposed at one side of the material support with an intermittent spacing feed of the material by any desired means. For this operation in a broader aspect it is only important that the punch be kept in alinement with the punched hole after the punching operation until the set operates, and that the punch be relieved from the punch block after it operates thereagainst. It is believed that the present machine is the first to employ a telescopically combined punch and set in combination with means for automatically feeding and spacing the material between operations.
