Application filed March 5, 1906. Serial No. 304,304.

bunched after the eyelet has been set by the cooperating setting dies, and is especially ap- Elicable in the manufacture of shoes or other (chute or runway,- cession wlth relation to the punch setting-die ether oods or goods in which it is desirable topunc a rgparatory'hole for the eyelet by the remova material by means of a ring ,or eyelet punch.

"It is the object of my invention to provide new and use u'l improvements in eyeleting machines, whereby the objections in eye- .leting machines as heretofore constructed are overcome, the said objections relating to the mannerof mounting and setting the eyelets,

eriect eyelets are encountered, and it is t e further object of my invention to provide new and improved means for accurately centering and sustaining the-eyelet with relation to the punching or setting devices and to the goods being eye- 'i'eted as well as for accurately centering and sustaining the cooperating setting tools with relation to each other.

Instancing the objections mentioned as the same are present in one type of eyeleting machine in use, this type of machine employs a punchwhichserves as a member of the cooperating setting dies, the punch, wh le operating as one of the cooperating setting dies, being intended to take inside of the barrel of the eyelet'forspreading said barrel, the eyekahpreparator "to such spreading operation,

eing mount upon the opposing setting die, there also being a spring-pressed finger reciprocable in said last-mentioned setting die adapted to receive the eyelet from the eyeletthesaid finger having rewhen the latterperforms its setting operation, the eyelet also, ation, being without central guidance for just prior to the setting operdefinitely positioning the eyelet with relation to the punch setting-die. The eyelet is therefore permitted ,to'wabble upon the opposing setting die with the result that when the approach between the eyelet and the punch settin -die takes place, the p'unch setting-die will often not be received within the barrel of the eyelet as intended but often makes contact with the outer ed e of the eyelet-barrel, thereby destroying t e eyelet and almost invariably damaging and often breaking the eyelet-punch and damaging the work, and causing stoppageof the machine for renewal of the parts. This vibration, wabbling and uncertainty of guidance of the eyelet is incident to the machines of various types of the general character mentioned, now in general use, and when it is taken into consideration that these machines are operated very rapidly, and that the eyelet is very light, it wil be noted that the vibrations caused by such rapid operations in a machine eyelet, causing uncertainty in its placement at the time the setting operation is performed. i

In other types of mac ines in quite general use the finger is adapte to make end toend contact with the opposing setting die, which in practice however occurs in imperfect alinement with relation to each other, owing to vibration of the machine and lost motlon, also permitting lateral movement of the eye: let in its relation to the opposing setting die in such manner as to often cause buckling or ing of the barrel end 01 the eyelet. These objections are serious in the practical operation of the machines and result-in material loss of stock operated upon as well as loss of eyelets and in'breakages in the machines and consequent delays; and imperfections in .eyeleting work are especiallyobjectionable when it is considered that imperfections in a single eyelet may destroy the usefulness of an entire ieceof stock.

It is the o ject therefore of my improved device to avoid the objections stated, and my invention consists in providing cooperating set'tin dies in a machine of the character mentioned, one of which setting dies has therein an eylet-receivingfingerhaving an enlar ement thereon adapted to receive the eye et of this character are communicated to the' inward crimping mstead of outward spreadsame on the irre for guiding the same, the other of said dies having a central bore adapted to receive the shank of said finger for positioning the said reducing end for beingreadily received by the opposing die and with a shoulder at said enlargement with which the end of said opposing die is adapted to engage preparatory to the setting operation for forming a guiding and setting face Without-obstruction against which the eyelet may either receive or impart injury; further in constructing said enlargement so as to project from its die slightly more than the distance which said barrel projects beyond the eyelet for locating said shoulder beydnd the eyelet when seated for causing said opposing setting dieto make engagement with said shoulder prior to engagement with said eyelet; further in providing apunch-setting-die With a bore of enlarged diameter adjacent to its cutting edge, i. c; larger than the bore of said punch at its cutting edge, for forming clearance for the ready release of the punchings of said cutter or punch, and in so associating said improvements and operatmg mechanism therefor as to cause proper relation and contact between the parts for forming the setting or the punch ing and setting functions, and further in the parts, and in the construction, arrangements and combinations of parts hereinafter more .fully described and claimed.

In the drawings: Figure 1 is a front elevation of an exemplifying machine embodying my invention. Fig. 2 is a cross section of the ular line x--:r of Fig. 3. Fig. 3 is a central vertical longitudinal section of the same. Fig. 4 is a detail in section on the line y-y of Fig. 3. Fig. 5 is a side elevation of the setting-die with the eyelet fingen'therein. Fi s. 6, 7, 8, 9 and 10, are sectional details illustrating the successive steps in the operation of my improved de- Vice; and; Fig. 11 is a sectional detail illustrat-ing the operation of my improved device in-connectionwith a separate punclr for performing the punching operation, it being understood that the punch and the members of the setting-dies have relative cross-reciprocation imparted thereto by suitable mechanism.

1 represents the frame of the machine, -on which a head 2 has lateral reciprocation on rods 3, a bar 4 having up and down reciprocation upon said head.

5 is a table or anvil on which the stock is i adapted to be fed and 6 is a bar adapted to have up-and-down reciprocation imparted thereto under the table.

7 is a -pressure;foot arranged to take against the stock on the table,- said stock being shown in the drawings at 8.

9 is a punch mounted'in the bar 4 and inthe present 'exemplification of my invention,

the eyelets, from which the eyelets are fed into the feed-chute into proximity with the setting dies. The chute has motion imparted into and out of the path of said setting-dies in ordinary manner so as to present the eyeletsone after the other to the finger 14.

15 is a drivingshaft operated in suitable manner and arranged to reci 'n'ocate the bar 6 up and. down as by being provided with a crank lti'having a crank-pin 17 j ournaled in a block 18 having cross-reciprocation in a slideway 19 of a collar 20 secured to the bar 6. The shaft 15 also carries a cam21 having engagement with contact faces'22 of a rocking frame 23 having an extension 24 con nected with an arm 25 of a sleeve 26, roclti'ng upon a shaft 27. The connection between ithe extension 24 and the arm 25 is preferably adjustable with relation to the oscillating axis of the sleeve 26 by having a stud 28 adjustably positioned in an arc-slot 29 in the arm 25. The sleeve 26 has a lug 30, and a collar 31 having an arm 32 takes aboutsaid sleeveand is readily adjustable with relation thereto by means of adjusting screws 33. The said arm 32 has a slideway 34 extending radially thereof in which a' block 35 has movement, a pin 36 being secured to the head 2 and journaled in said block for-translating the rocking movement of said sleeve 26 into laterally reciprocating motion of'said head. In order to further govern the length of cross-reciprocation of the head, a bellcrank lever 37 rocking on a pin 38 and articulated with said extension 24 by means of a link 39 is provided, screws 40 having jamnuts 41 liinitingthe movement of said boll- "crank lever, which is adapted to beset in motion by a connection 42 operated fronra treadle or other suitable lever. The shaft 15 also carries a cam 43 having engagement with contact faces 44 of a rocking-frame 15 on an arm 46pivoted at 47 to the main frame and provided at its other or swinging end with a segmental-rack 48 engaginga segment 49 on shaft 27 for rocking the latter, the said shaft having an eccentric 5O journaled in a block 51 upon which a slide 52 is supported. and by which said slide is moved, said slide being adjustably secured to the bar 4'by means of set-nuts 53.

The pressure-foot- 7 mounted on a rod 54 adapted to be reriprocated by a lever 55 pivoted "at 56 to the mainframe and automatically-operated 'by a cam 57, the said pressure-foot also arranged to be operated by a lever 58 ivoted to the frame and connected with a oot-treadlc or other operating device.

The eyelet-chute] 1 is shown as operated by means of a lever 60 having a yoke 61 taking about the cam 57 and connecting with said chute for oscillating the same.

As thus far described, the machine operates, broadly stated, as follows: Stock being placed upon the table under the pressureoot, the bar 4:,lS caused to descend for causing the punch 9 to pierce the goods against the anvil-or table 5, and immedlately has a slight rise imparted thereto for relieving its contact with said anvil for permitting cross-reciprocation of the punch withoutinjur to the anvil or punch and for bringing sue punch into longitudinal plane with the setting die 10 for performing the setting operation. In such cross-reciprocation shoes 62 makecontact with the lower side of the goods forgforcing the goods upon the punch, the operation beingsubstantially as more fully shown and described in Letters Patent No. 686,928, granted P. It. Glass, November 19, 1901. The bar 6 is preferably hollow and has a rod 63 adjustable therein making contact with a shell 64 upon which the setting die 10 is supported, the setting-die 10 being secured to said bar by a socket-nut 65. The finger 14 is slidable in the setting die 10 and isinormally held in upward position by means of a spring 66 taking against a heel 67, which serves as a stop for limiting the upward movement of the finger. The setting die 10 has a setting face 68, and said finger at said setting faceis of a diameter coinciding substantially with the diameter of the eyelet which is arranged to be received about the finger, forming an eyelet-guide 69, which is of a length' equal to or preferably sli htly lon er than the height of the eyelet a ove said setting-face and ending in-a shoulder 70 between it and the reduced shank 71 of the finger, the said reduced shank terminating in a reduced end 72 for purposes presently to bee): lained. Eyelets' usually have a tapering arrel and I prefer to taper the guide 69 'as shown. The punch 9 has an annular cutting web 73 having a cutting edge'74 adapted to form the hole-in the goods whichis subsequently to receive the eyelet. In the exemplification ofmachine shown, the goods, such as leather, after being punched, is transversely fed by means of the punch, and forced upwardly upon the cutting web. The punch 9 forms one of the cooperating members of the setting dies, and

' the part 9 may form one of such cooperating sequently taking about-the eyelet-guide 69,

motion is imparted to the parts for first causing relative'approach between the cooperating setting dies for seating the cutting edge-74 .upon the shoulder 70. It will further be noted that the reduced end 72 of the finger will readily find the bore 75 in the unching die 9, so as to revent end contact Jetween said end of sai finger and the said die, irrespective .of irregularities or vibration of the chine, the said reduced shank 71 of the finger thereupon finding ready seat within the said arts or lost motion in the mabore and causing accurate relative longitudina l and lateral setting between the cooperating setting dies. The said edge 74 having found seat upon the shoulder 70, and the diameter of the edge 74 being at least as small as'the diameter of the shoulder 70, a substantially continuous guiding and setting face is formed against which the barrel end of the eyelet may be forced without meetin with obstruction or disfigurement, the we 73 beingm ade flaring away from its outer end in ordlnary manner for a setting die. The shoulder 70 is preferably a flat shoulder against which the cutting edge 7 4 is adaptedto make flat contact, thereby preventing injury to the cutting edge and preventing its burring or flaring as would be the case if said cutting edge were caused to take'against a slanting or curved surface. The said cutting edge is also preferably of slightly less diameter than said shoulder. has been made between said end or cutting edge and the shoulder 70, further relative movement between; the setting diesis causedfor forcing the eyelet-barrel through the goods and for flari the outer end of said barrel for setting t e eyelet into the goods, the punched hole, in the present exemplification, being of less diameter than the outside diameter of the eyelet.

The exemplification shown in Fig.- 11, shows my implroved device applied when a separate punc is employed. 76 is a separate unch, 9 is the setting die provided with a engaging face 7 4 or extreme end or eyeletguide on the die 9 is ada ted to make engagement with said shou der 70, prior to the relativemovement between said finger and eyelet, whereupon the finger is moved by its opposing die and engagement with the barrel of the eyelet immediately transferred from said eyelet-guide on said finger to the eyelet-guide formed by web 73 on saidopposing setting die 9, the parts also continually mamtaining lateral support between After seat prior to..the beginning of the actual setting said finger and both said, dies for sustaining the dies in centered relation irrespective of vibrations or lost motion. ll hen said die 9 is used as a punch I enlarge the bore 7 5 adj-acent to its cutting edge, for tl'orming aneularged bore 77, which I have shown as taper-- mg or flaring. The object of this is to pro-. vide ready release of the punchings 2 in the bores made by the cutting operation, so-that the shank of the finger may have ready entrance into the bore of the punch when the latter is used 'as a punch and for permitting the finger and its setting die to remain relatively stationary until the seating oi the punch edge or face upon the shoulder 7 U.- The punchings are discharged through a. passage 78 having an 'o 'iening 79 in the bar 4.

In my improved construction further, the eyelet has sent upon -a central eyeletguide which is stationary with relation thereto untilthe eyelet-guide of the opposing setting die is in close juxtaposition thereto, the reduced shank of said finger having meanwhile entered said opposing setting die, thereby insuring-that, the 'eyelet and the cooperating setting dies shall be centered ancrlaterally supported all with relation to each other operation, thereby nullifying the results, oil vibration and lost motion in the machine, and permitting exceedingly rapid operation and excellence of workmanship with minimum loss of material.
