To all "whomz't may concern:

Be it known that I, PERLEY'R. Gmss, a citizen of the United States residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description,-

the right or fair side of the upper faces downwardly so that the operator cannot readily locate the point of insertion with the desired accuracy. This diiliculty is especially apparent when eyelets are to he set in uppers provided with so called military stays. Such stays consist of narrow strips of leather which. are either simply ornamental or are secured to cloth or leather uppers of shoes to reinforce the row of eyelets. It is important to insert-the eyelets centrally into the military stay because an eyelet that is closer tooneside of the stay than to the other detracts from the ornamental appearance of the shoe, and there is also danger that the hole punched for such eyelet will cutone of the seams uniting the stay with the ljippe and cause the seam to unravel quickly under the lacing strain.

As a rule military stays are not parallel to the lacing edges of the upper. One reason for attaching these stays in a relation otherwise than one parallel to the lacing edge of the uppers is toiinprove the appearance of the shoc -as, for example, by arranging the two series ct cycles in diverging relation. Another reason is that it requires operators of more than usual skill to attach the stays exactly in parallel relation to the lacing edges of uppers. In eyeleting uppers pro X'llltltl. with military stays it is therefore im 'n-acticahle toemploy the usual edge gage oi" eyeleting machines to indicate the locationot' thesetting points. Hitherto it has been customary in eyeleting uppers pro 'vided with military stays to PBILEOIIIItWO' distinct operations in the first of which the upper, with the right or fair side uppermost, is presented to a punching machine, whereas in the second operation the upper is presented in inverted position to an eyeleting machine, the previously punched holes serving to indicate the location of the points at which the. eyelets should be inserted. The general object of the presentinvention is to provide a single machine by the use of which these and similar disadvantages may be obviated so that accurate location of the eyelets in the work will be insured.

With these conditions in view an important feature of the present invention con sists in a gaging device of relatively small dimensions constructed and arranged to indicate by its position upon the upper surface of the work the precise point at which the eyelet hole will hcpunched and the eyelet inserted when the machine is set in operation. As herein shown the punch is disposed heneath the work support 20 so as to punch upwardly and the anvilagainst which the punch acts is disposed above the work and has also the function of such a gaging device. Accordingly, in using the machine of my invention, the work may he presented right side up and the anvil will cover merely the eyelet receiving area of the work while peri'l'iitting a clear view of the surrounding work. Consequently, in dealing with an) upper having military stays the operator has only to position the workso that the anvil will cover the desired eyelet-receiving area of the stay to insure the correct location of the eyelet.

Another feature of the invention consists 5 in an anvil or other gaging device so com hined with worlcfecding mechanism of the machinethat its initial position will. be de termined in. accordance with thelength of the steps of the feeding mechanism. Inthe machine herein shown the anvil is connected to a teed-regulating lever so that its posi tion will be controlled by the movement of the lever, and theanvil consequently indicates not "only the positi on at which the first eyelet is to'bc inserted. hutalso, by its dis tance from the eyelet inserting die, the length of the feedingstep to beiinparted to elevation with parts of the frame broken away; I

Fig. 4 is a fragmentary view in perspective of the raceway operating mechanism; Fig. 5 is a front view of the machine;

Figs. 6, 7 and 8 show diagrammatically the relative positions of the operative parts of the machine, beforeand after the punching operation and at the completion of the setting operation.

Fig. 9 is a fragmentary view of an upper provided with a military stay.

The machine frame 2 is provided with bearings for the main shaft 4, carrying on one end a driving pulley 6. A clutch mechanism of well known type is interposed between the pulley 6 and the main shaft 4, and the starting and stopping of the ma chine is controlled through this mechanism.

A combined punching and setting tool 8 is mounted below the work table 9 in a head 10, to which vertical reciprocations are imparted by toggle links 12, 14. The latter of these links is pivoted upon a rod 30 mounted in the frame of the machine while the link 12 is slidably pivoted on a rod 13 held in forked arms 011 the lower end of the head 10. A link 18 connects the knuckle joint 16 of the toggle 12, 14 with the extended arm 22 of a cam lever 20 pivoted to the machine frame 2 at 24. The forked end of the cam lever 20 surrounds a cam 26 mounted on the main shaft 4. The cam 26 is arranged to move the toggle links 12, 14 slightly beyond the straightened position in order to relieve the pressure of the punch upon the work after the punching operation. The head 10 is mounted for movement within a casing 28 which is arranged to slide laterally upon a pair of stationary rods 30, 32 in feeding the work.

The punch 8 is elevated from beneath the work and acts against an anvil 34 secured tothe lower end of an anvil bar 36. The anvil bar 36 is normally fixed in position but is mounted in a casing 38 which may be adjusted laterally on two stationary rods 41,142. The face of the-anvil 34 is located approximately in contact with the upper HGSS.

surface or right side of the work and indicates exactly the point where the eyelet to be set. The dimensions of the anvil approximate those of an eyelet for a considerable part of its vertical extent and hence are such that it does not obstruct the view Of the work around the setting point thus giving the operator opportunity to locate the setting point with the greatest exact- An adjustable forked foot 40 is scoured to the lower end of the anvil bar 36 to hold the work on the end of the punch 8 during the feeding movement, but the foot 40 does not interfere with the visibility of the work around the setting point.

The feeding movement of the punch 8 is derived from a slide 43 which is reciprocated horizontally by a cam 44 (Fig. 4) mounted on the main shaft 4. The cam 44 acts through links 46, 48 upon an arm 50 secured to the upper end of a shaft 52. The lower end of the shaft 52 is connected with a forked arm 54 which engages at its for ward end with a block 57 on the casing 28 of the head 10. The length of the feeding movement of the punch 8 can be varied by the manipulation of a spacing lever 56 which shifts the point of connection of the links 46, 48 through a link 58 and which may be suitably held at the desired point. A treadle connection 57 is provided which may be used for moving the spacing lever if desired. The initial or stop position of the punch will be determined by the setting of the spacing lever 56 but its final position after feeding the work is invariable and always in alinement with the top set.

The anvil 34 may be elevated to permit the ready insertion of the work by the following mechanism: The upper end of the anvil bar 36 is slidably connected with a rod 63 extending between the arms of the link 62 of a pair of toggle links 60, link 64 connects the knuckle joint of the toggle 60, 62 with an arm 65 seeurei'l to a shaft 66, to which a treadle arm 68 is fastened. A spring 70 acting upon the treadle arm 68 tends to hold said arm against an adjustable stop 71 so that the toggle links 60, 62 are maintained slightly bcyoinl their straightened position, thus rigidly support ing the anvil in a position immediately ad jacent and preferably almost touchingthe work. 72 connected with the arm 68 the toggle 60. 62 is broken and the anvil elevated. The casing 38 carrying the anvil bar 36 is adjusted laterally on the rods 41. 42. move- Upon depression of a treudlc rod 1;

by reason. of its sliding connection to the pin 63, by a lever 74 pivoted in the frame and having at its outer end a roller 76 which runs in a cam track 78 in the spacing lever 56. When the spacing lever 56 ill b mme .setlto determine the lengthotthe individual feeding movements, the anvil 341: is adjusted into proper initial position but after having been thus adjusted has no movement duringthe regular ope ation of the machine. This setting of the spacing lever will also adjust the, stop :position of the punch 8 to correspond with the adjusted position of the anvil. 3i, as previously described.

The uppersetting tool, is secured .to the lo-Werend 01E abar 82 which is; guided inthe frame for vertical movement but has no lateral movement.

l lyelets are supplicd'to the uppersetting tool by a raceway 94: Whichiislpivoted to the frame at 95 arul is oseillatedby connwtionswiththeslidc4l3 (see Fig. l). The slide 4L3is provided with a projection 96 carrying aublock 98. Theiblock 98 is=received vbetween the arms of. a forked lever 100 secured. :to the lower end of a vertical shaft 102. The upper end ofthcshaft 102 carries a yoke piece 101i, between the arms of: whichis pivoted asecond yoke piecelOfi. The yoke piece 106 is provided with an arm 10%? having an adjustable stop screw which is normally held against the hub of: the yoke piece .104 by a spring 110. Between the arms oi the inner yoke 106 is disposed a block 112 having verticalpins 11-4; arranged to slide freely through the arms of the yoke piece 106. A pin 110 extendshorizontally ironrthe block 112 through bosses 118 on the raceway94. All these parts act normally as a single piece, allowing the necessary lost motion. WVhenNitis.desired to hold the raceway in inoperative position, the arm 108 of the inner yoke 106 isswung in opposition to the tension of the spring 110, and the raceway thus shii'tted out of the range or the upper setting ,tool. .Adjustmeat of the eyelet delivering position of the raceway is eflected by means of the screw in said arm 108. A belt connection 130 provides for the actuation of .theusual agitator mechanism.

The described arrangement oi the raceway o'tlers particular advantages. The operator can actually see the lowermost eyelet in the race ay as it is picked out by the upper set and can stop the operation ofthe machine in time in case the raceway should iiail. for any reasonto deliver an eyelet.

The upper setting device is verticallyladjustable to adapt the machine to operate uponstock oi varyingthickness. Thebar 82 carrying the upper set-ting device 80 is provided with a block 120 (see. Fig. 3) which isreceived between the arms of Na. fork .12-2 ofmthe crank. lever 84:.

The punching and setting tool 8 is then moved laterally With the work to a position beneaththeupper setting tool, so thatthe tool .may perform its upsetting function during the insertion of the eyelet. The

upper setting tool 82 is now lowered, the barrel of the eyelet inserted through the work and upset by the cooperation of the upper setting tool and the tool 8 as shown in Fig. 8. At the completion of the setting operation the parts of the machine are returned to their initial positions as shown in Fig. 6 ready to repeat the cycle of operations. 7
