To all 'whom it may concern.'

Be it known that I, FRANK L. I-IARMON, a citizen of the United States, and resident of Beverly, county of Essex, Commonwealth of lifassachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to eyeleting machines of that type wherein the eyelets are automatically inserted in the material and clenched with an automatic feed 0f the material, to space the eyelets between successive eyeleting operations. A prime object of the invention is to provide a machine of this type adapted to insert and clench the eyelets at a much higher speed than has heretofore been feasible, and to so dispose the working parts that they are exceptionally convenient for control by the operator, being all disposed at oneside of the material support. To these ends one important feature of the invention consists in a multiple eyeleting machine of the material feeding type that is selectively duplex or quadruplex in its action, all the active work of eyeleting being done from one side of the material. In accordance with this feature of the invent-ion the machine may be duplex to enable two pieces of material lying side by side and edge to edge to be eyeleted at the same time, or it may be used duplex to enable two eyelets along the line of feed in one piece of material to be eyeleted at each operation, or it may be used quadruplex combining these two duplex features. If believe the present machine is the first duplex or quadrupleX eyeleter that is capableof eyeleting two pieces of material lying side by side with their edges toward each other, and also the first machine of the material feeding type wherein a plurality of eyelets are inserted and clenched at each eyeleting4 operation from one side of the material. A further feature of the invention consists in a novel construction of horn or material support shaped so that the two curved sides of a shoe quarter may be eyeleted at the same time while they are placed with their edges toward each other thereon. A further feature of the invention has to do with adjusting means for variably spacing the two punches arranged in the line of feed, according to the distance desired between the eyeletsg'this feature in its preferred and more complete embodiment having also provision whereby the same adjusting means that spaces the punches is also adapted to vary the stroke of the material feeding means correspondingly so that a single adjustment is all that is necessary to vary the eyelet spacing in this type of machine. The above and other objects and features of the invention will be better understood from the following detailed description taken in connection with the accompanying drawings and will be thereafter pointed out in the appended claims.

Referring t0 the drawings:

Figure l is a side elevation of a machine constructed in accordance with my invention;

Fig. 2 is a sectional detail showing a telescopic punch and set mechanism that is preferably employed in connection with my invcntion;

Fig. 3 is a plan view of the machine; and

Fig. 4 is an end view of the immediate working parts and material support looking from the left in Fig. l, the operating mechanism being omitted for lthe sake of clearness.

At the front of the base support l is a bracket block 2 constituting a work supporting member, it for this purpose being eX- tended back as a horn 3. This work supporting horn and the operative surface plates adjustable thereon as presently described are curved upward from the end of the horn as seen at l to permit two pieces of material such as a pair of curved quarters.

of a shoe to lie thereon with their edges toward each other in parallelism as later more fully explained. The curved surface of horn 3 has slidably fitted thereto correspondingly curved plates 5, 6, the plate 6 being shown as superposed on the plate 5, the plate 5 being extended beyond the plate 6 where it is formed with outer clenching surfaces 7 and the plate 6 having its eX- tremity formed with inner clenching surfaces 8. These two plates have upstanding lugs 9, 10, at their respective ends bearing journal pins connected with links 1l, l2 respectively which in turn are connected with the mountings of the pairs of relatively adjustable punches as presently described through pins 13, 14 connected with the respective punch mountings and pivotally connected to saidlinks as seen at 15. A suitable presser foot formed as a spring plate 16 extends from the block 2 to the end of the horn with long wide slots 17 at its outer portion to accommodate the lateral punch movements to be presently described. The outer end of' the horn is also shown asV equipped with a thin plate 18 carried by a bracket fixed to the horn and extending in over the sli de plates 5 and 6, being suitably apertured to uncover the clenching irfaces oi 'said plates as seen at 13a and serving to support the material so that it will not'be moved by Jr'rictional engagement with said plates alone. rlhe base 1 is equipped at a distance bach from the material support with a transverse slide way 19 in which is fitted a slide 20 which extends across the base and is equipped with journal bearings for the operating levers to be now described; rlhis slide has spaced apart upstanding lugs Q11 provided with journal bearings to serve as the fulcrum of a lever 22 which extends back from this fulcrum point with a roller 23 at its rear end engaging a wide peripheral cam 24 fixed on a shaft 25 which is the drive shaft of the machine journaled in suitable bearings in uprights 26 at the rear of the base and having thereon a driving pulley` 27 with a suitable stop clutch 23. rilhe lever 22 has at its 1liront end a head 29 in which are fitted a pair of telescopically com- Y bined punch and set mechanisms 30, 31 disposed in parallelism endwise of the lever. ihe lever 22 has its outer end portion equipped with a lateral projection adapted toV serve as a slide support for slide bloclr 33 fitted thereonto which bears a head 34 equipped with a second pair of telescopically combined punch and set mechanisms 35, 35 arranged iny parallelism with the lirst mentioned pair 30, 31 and similarly spaced apart endwise of the lever. Means is provided whereby the pair of punch and set mechanisms 35, 36 may be variably spaced from the pair 3G, 31 and for this purpose l provide an adjusting pin 37 having threaded engagement through the lever 22 and also through the slide bloclr 33, with a knurled operating head 38 at its outer end. rl`he adjustment of thisl pin` serves not only to space the pairs of punch and set mechanisms apart variably as recuired but it also determines the extent of lateral operative movement olf the pairs of punches for feeding the material and spacing the eyelets. For the purpose of effecting this lateral spacing movement a striker 39 for engaging the head ot the adjusting pin 37, is mounted on the end of a lever 40 fulcrumed at 41 to a rear portion of the base support with a roller 42 at its inner end` inA position to engage a lateral cam 43 fixed' on shaft 25. The outer portion of this lever is acted on by a spring 44 fixed at 45 to an extension of the base so as to hold the roller 42 against the earn 43. Thus the extent that the lever 22' carrying the punch and set mechanisms along with the slide 2O will be moved laterally by the lever 40 is determined by the in and out adjust nient of the pin 37 as threaded in said lever, since the more said pin is adjusted out toward the striker head 39, the less lost rnotion of the lever there will be and hence the greater lateral shifting movement of the lever for spacing the eyelets. rlhe threads on the pin 37 are so. arranged that those engaging the slide block 33 will move it latorallyl away from the lever 22. by the ksame amount that the adjustment of pin 37 toward the head 39 lengthe-ns the operative or spacing strolre. 37a on the portion of said pin engaging the slide block 33 are of coarser pitch than those. 37b on the back part of the pin engaging thel lever the pitch ratio being two to one; for eXnnple assu-ming the threads 3,7 to be twentytwo to the inch, the threads 37b will be 44 to the inch. A suitable loclr nut and washer 46 may be provided for securing the threaded pin 37 against turning when properly adjusted, by its locking action against the block 33. rlhe pins 13, 14 which before described are connected to operate the slide plates 5, 6, are fixed respectively toi the lever 22 and to the block 33 and hence areI adapted to move said plates so as to lreep the clencliing surfaces 7, 8, underneath and in alinenient with the respective sets of the two pairs throughout their range ot adj ust ment toward and from each other, as Well as causing said clenching surfaces and the punch blocks associated therewith on the plates 5, 6 to be moved with the punch and set mechanisms in their lateral movement for feeding the material and spacing the eyelets. A tension spring 4'? has its ends engaged with the slide 20 at 43 and with a post 49 upstanding from the base and moves the slide over to the limit of its movement to- Ward the striker 39 as far as permitted by a suitable stop device 50` on the base to entherewith. jill ot the punch and set mechanisms are alike and each consists in a hollow set 51 threaded for adjustmentin the head which carries it with a lock nut 52V to secure it in adjusted position. in this is slidably fitted a tubular punch 53 which normally projects therefrom being held in such projected position by a spring 54 secured at one end to the head and engaged at its other end with a collar 55 threaded on a rear extension of the punch, this colla-r being interloclred on the punch between nuts 56 and 57, the latter of which serves as a gage to determine the extent of' normal forwardl projection of the punch. Means is provided whereby the punches are held posi- To efliect this the threadsk tively projected from the sets and moved downward for the punching operation and for this purpose l provide a lever 58 having a head 59 with a face wide enough to engage all the punches in punching position, this lever being fulcrumed at 60 to an upright 61 extending up from the base l with a roll 62 at its rear portion engaging a peripheral cam 63 fixed on shaft 25, this roll being held in engagement with said cam by a coil spring 64 secured at one end to the extremity of the lever 58 and at its other end to the base as seen at 65. Another suitable spring 66 is mounted in position to hold the roll 23 of lever 22 against its cam 24.

lt may now be understood that in use, starting from the initial position shown in the drawings the two pairs of punch and set mechanisms 30, 31 and 35, 36 are moved downward under the action of the rising portions 24a, 63a of peripheral cams :24, 63 which thus cause all the punches and sets to be moved down together with the punches held positively projected from the sets 59 by lever 58. As this occurs, each punch takes 0H an eyelet e from the end of suitable yelet raceways indicated at 67 the eyelets sliding back on the punches so that their flanges rest against the ends of the sets. As the downward punch movementcontinues, the punches are forced through the material against the punch block surfaces at the ends of plates 7, 8, which punch block surfaces, it will be understood in the present embodiiient, are within the annular 'rooves which constitute the clenching sur aces. Thereupon the lever 58 is moved back by its spring as permitted by a receding portion 63b of its controlling cam, so that the punches are now only held yieldingly forward by the springs 54. Thereupon the sets are moved farther down to slide the eyelets olf the punches through the material and to clench them in the punched holes under the action of a further raised portion E24b of the cam controlling lever 2Q. lifter this occurs the latera' cam 43 is in position to act on the roller 4,2 swinging the striker head 39 against the head of the bolt 37 and shifting the slide 20 bearing the punch and set mechanisms to gethcr laterally for spacing the eyelets the required distance according to the adjustment of threaded bolt 37 as previously explained. lt will be understood that this lateral shifting movement of the punch and set mechanisms occurs while they are engaged with the clenched eyelets in the two pieces of material, and that thev plates 5, 6 bearing the respective punch block and clenching surfaces partake of this lateral shifting movement sliding on the circularly curved slide ways 4 of the horn 3. Thereupon the punches and sets are withdrawn clear of the material this being permitted by raised portions 24, o3c of their respective cams, when a lowered portion of cam 43 permits lateral return of the slide 20 bearing the punches and sets back to initial position.

The two pieces of material m, m, adapted to be operated on simultaneously as described, may be fed into the machine gaged laterally against a central rib 68 upstanding from the plate 18, there being a suitable receiving mouth formed by a flaring end 69 of the presser plate 16 with a correspondingly flared member oppositely fixed to the end of the horn. lt will be understood that the curve of the horn as indicated at 4, and of the material support slide plates 5, 6 fitted thereto, will depend on the kind of material to be eyeleted, for example, if eyelets are to be placed in the edges of two normally fiat pieces of material the horn and slide plates would of course form a plane surface. The form shown is about the degree of curve adapted for holding the two sides or quarters of a low shoe with their edges in parallelism against the guide rib 68 as required for properly positioning the lines of eyelets. It will be understood that for high shoes the curve might be considerably higher than shown, but in all instances with a correctly formed curve or incline the two edges of a pair of material pieces such as shoe quarters and uppers may be made to extend in substantial parallelism for the eyeleting operation.

lt will be understood that when it is desired to use the machine duplex instead of quadruplex as described, the pair of punch and set mechanism carried by the head 34 may be dismantled so that there will be only one punch operating on each piece of material, or the inner punch and set mechanisms 30, 35 of each pair may bel dismantled so that two eyelets will be inserted and clenched on one piece of material at each operation. While 1 have herein shown my invention as carried out with telescopically combined punch and set mechanisms, it is to be understood that in certain broader aspects having to do particularly with plural eyeleting at each operation either on a single piece of material with a feed and spacing of the material, or on two pieces of material set side by side and edge to edge, the use of the telescopic punch and set combination while desirable is not essential nor is the invention in these respects limited thereto. rlherefore where the expression punch and set mechanism or the like occurs in the appended claims unless particularly so stated it is not to be understood as being limited to telescopically combined punch and set. Where the expression eyeletting operating or the like occurs in the claims it is to be understood as referring to the punching of the holes, the inserting of the eyelets therein, and the clenching of the eyelets. l am aware that each of these features as well as various other features of the invention may be employed advantageously in other relations than those shown and l; therefore desire the present embodiment to be considered as illustrative and not restrictive, referring rather to the appended claims to indicate the scope of the invention.
