,Figg'l is a perspective view kofthe -stud r placing mechanism.

y Fig. 16 isa yperspective viewfpartly Vin section of asupply hopper and its operat-4 ing mechanism which supplies studs to the studk receiver.

The illustrative mechanism has been jde` signed in this'instance to attach the' studor ballfpart ylO`(l1`ig. 1?) vof a snap fastener,

The attaching means 1s here shownA as a rivet The stud part'comprisesabase' having a projectingfstud, in this case in the forni of a'hollow ball integral with thek base. The stud'is usually made from sheet metal'a'ccord ing to wellknown practices; and it is of well Y known construction. yFurther l description thereof is unnecessary in this connection.

The attachingrivet 11in this instance, has

' aihollowstem Ll2' (-whoseheight suinciently exceeds that necessary to pass'through the 1'? fabric to allow a margin for upsetting with-f in thehollow stud of the fastener) designed top'afss throughgtlie fabric to which :they fastener is `attached and to enter the in-V yterioi lof 'the stud andto be upset therein.

Since .the opening intorthe'interior ofthe ballgissomewhat restricted as `compared with rvthe internal diameter thereof, the enlarged fh'eadforme'd inside Vthe ball by upsetting the t rivet vsecurely holds the elements' of the fastener clamped to the interposed fabric'. yThe elements of the fastener part above referred to are attached to yan interposed webk y of fabricorthelike by vcooperating.dies y'1 3 yandlwhich las they. arehroughty together 'i ony opposite fsidesl of the web of fabric cause the rive/tmtopenetrate the fabric, enterjthe n fastener inemberfand tobe upset therein (Fig.` 7), f The ltop of the rivet is indented. y .'(andin thiszcase also perforated) av'sfindi-v cated 'at llligl'lli). thereby leaving a relai y' y vtively squarefor sharp edge tothe rivet 4so, that it serves in cooperation with thestlld n member to punch or [pierce the fabric'.

The upper die mechanism comprises'in ad# VLai dition tothe elongated plunger 16Vo'f theV die 13, a surroundingY reciproeable sleeve 17 which is slidably mounted inthe stationary housing18. of the machine. While the die Vplunger 16 is constructed and arranged to slide within the sleeve 17, it is momentarilyl h-eld immovable A"therein by compression spring 19, of suflicient stiffness to permit the die to yield relative to tlie'sleeve'1.7 only when the elements of thefastener have been ysuflicientlytightlycompressed together on oppothe length of the plug 22 the initial compres sion'of the spring7 19 maybe varied soas to supply the proper compressiverforce to the fabric and the 'fastenerelements The .end vof the Vsnap fastener engaging die is shaped to conform to that portion of the surface of the fastener part (in this .case the ball or stud portion) which operatively engages the mating part yof the snap fastener (inthis case thesocket part). For this purpose the lower end of die 13 is provided with a recess 211 which conforms to and surrounds theprojecting stud sufliciently snugly to preventany distortion thereof during the assembly operation and the upse'l ting of the-rivet inside the stud. In this way the fastener stud suflers'no change in size inthe attaching operation such as Vwould destroy itsproper cooperating lity with the socket part ofv the fastener. llVhe'n fastener studs iofdierent sizes or contours are attached acorrespondingly different die 13 maybe employed.- Adjacent the end of the die 13 is a stud holder in the form of a loop spring 25 wliich holds the studV inv place at the end of the die (by engagement with the neck or baseof the stud) prior to the assembly operation. In the present` case Y the spring is seated infa recess v26 atl the end ofthe die in which recess it vislield by a kretaining sleeve 27 having Va flange 28 atV thej lower end` which extends `at least partly over the recess 26 to holdthe spring in place. The sleeve may be secured to the diein any yap-V propriate manner as by a screw 29.` Y Individual fastener studs areplacedin operative relation to the die by placing mechanism in the form of an oscillating and rer. Mciprocatmgarin 30 which. oscillates to carry.

a stud into alineinent with'the die and recip-V rocates to move the stud Yvertically into engagement with the spring holder 25. The

arm 3 0 is'providedwith a head 31fwhich entersthe interior-ofthe stud to locate it properly onthe arm lfor placing purposes. The

stud Aparts are supplied in :this instance to thenplacing mechanismbya stud raceway 32 ses whose cross section is such as to maintain the studs in a single column of uniformly arranged studs.V The lower .end of the raceway is controlled yin the present case by a 'spring' device 33 having a pair of spaced spring 34 separatedaJ distanceslightly 'less than the diameter of the base of the stud,

thus preventing the escape of studs from the raceway. The spring legs 34 are designed so as to separate topermit the passage of'a fastener when the latter is-positivelyinoved by a force somewhat greater than the `pressure of the column [of studs against the spring device. ln thisinstance, the release Vof a single fastener in the manner above described is effected by theplacer arm whose head 31 enters the lower studxand in moving forward causes the stud'to'sprcad the spring legs 34. i f

` The studs are supplied properlyyarranged tothe raceway l32 bya hopper 35 within which rotates a disc 36having passages 3.74 adjacent its periphery which permit the escape of Astuds from the hopper into the raceway 32 when they are located in proper position,'i. e., with the stud portions facing one way.v The disc 36 is rotated by a sproclzet38 driven by a sprocket39 on thev shaft which drives pulley40.`

The placer operating mechanism comprises in 7hisV instance an oscillating bell crank 41 mounted vona vertically reciprocating pivot rod 42. l The placer 30 isadjustablymounted at o-iieend of the bell crank arm (Fie. 15') by ymeans of a clamp screwl3 andan adjusting screw t.,` This construction permits the placer to bey adjusted Yrelative to the endof the die so that it willV accurately aline a tener vstud therewith.Y The other .end of the bell cranlrA arm isV .connected witha link Vby means cf'which it isoscillatedabout the axis of shaft s2, thereby giving theV placer device an oscillating movement between a point in alinement with thedie 13 and a point in alinenient with the lowest fastener clement in theV raceway 32. rllhe linlr L15 is connected with a reciprocating slide l'slidably mounted on the machine by screws 47 vwhich pass through slots `therein. AThe slide is pro vided with a cam rollflQ whicliis actuated by the .maincam 50 mounted on vmain cani shaft 51. A spring 52 connected with the slide bymcans of a pin 53 serves to hold the cam roll 49 iii operativeengagemeiit with the cam V50.]y c p Y Pivot 'shaft 4f? is reciprecated vertically to give the placer mechanism the necessary verticalftravehby lever pivoted vat 55 to the machine and'engaging the rod with its outer end 53.1 y The inner end 57 Yof tl er lever is provided with a cam roll which engages a cani surface 58 provided by thepe'ripheral Ycoiitourr'ofmaincain 50.
