the frame lt of g i i *Fig. 2 illustrates in aconventional manher ar otarybutton hoppe lg f hi h biittons-are fed along a chuteQO to a button receiver 21 located immediately beneath the reciprocating plunger 17 hereinbefore referred to. Thebuttonsetting plunger 17:

is located directly over an anvil 22 to which ers whereby thebuttons are securedto a garment and to feedthem bythe upper end of a downward'extending fastener chute'Q-i,

frame 14 of the machine at 26, and which.

having overhanging sides as illustrated in the drawing to thereby hold the fasteners in place and as is usual in fastener feeding onto the anvil upon which they rest with their point extending upward, as illustrated in Fig. 5 of the drawing and as will be hereinafter explained in detail.

The reference .numeral'25 designates-an oscillating lever pivotally secured to the lever is provided with an elongated slot 27 in which a roller 28 carried by the oscillating lever 16 travels, whereby oscillatory motion is communicated to the said lever as will be understood. This oscillating lever is I with a pitman 81 which serves to communicate rotary motiontorthe hopper 23 through suitable ratchet mechanism designated as a whole by the reference numeral 32, Fig. 1,

but which, mechanism is not illustrated in detail for the reason that it, as well as the hopper itself, form no part of the invention.

to which this application relates,

The reference numeral 33 designates a reciprocating stop designed to operate through an opening 34 located in thebottomjwall and adjacent the lower end of the fastener chute 24, and which stop arrests the downward movement of the fasteners in the chute when the same is in its uppermost position, as illustrated in Fig. 6. This stop is. shown as located at the free end of an oscillating member or lever 35, the other end of which is pivotally supported at 36 in lugs 37 formed upon the under side of the chute 24.

' The stop 33 is moved in a direction to bring it into position to arrest the downward movement of the fasteners in the chute by means of a spring 38, actmg upon the member 35, and in a direction to release the} fasteners by means of an oscillating oper ating member or arm 39 which engages a cam surface or shoulder 40 upon the member 35 and swings the same awayyfrom the chute, as shown in Fig. 7, this'movement being against the tension of the spring 38 as will be understood. The operating arm 39 is securedto the, lower end of a short oscillating shaft. 8:2 supported in a bearing formed in a lug 41 projecting from the fastener: chute 24, which shaft carries at its upper end a plate 42 which in turn is provided. with a downward extending pin 43,

it being understood that the plate 42 and operating arm 39 are connected with one another in a unitary manner move in unlson.

Osclllatory motion is communicated to the oscillating operating member or arm 39 and, consequently, to plate 42 through a pitman 44 as shown in Fig. 10,the upper end of this pitman being operatively'connected with the oscillating lever 31 hereinbefore referred to and as best shownin Fig. 2. The upper end of thispitman is provided with a slot 45 in which a pin 46 carried by the lever 31 moves, so [that said .last mentioned lever may partake of a considerable movement before the pin 46 comes into.

contactwith-the end of the slot 45 and before beginning to transmit motion to the pitman 44. The lower end of the pitman 44'is also provided with a slot as. shown at 47in which a pin 48 carried by the operating member or arm 39 moves. A spring 49 is also provided one end of which is secured to the pitman 44 while the other end is secured to the pin 48 It will therefore be appreciated, referring to Fig. 5, that moltion is transmitted to the operating member or arm 39 through the spring in the normal goperation of the machine,.and that iffor any reason the fastener feeding mechanism Ebecome jammed so that the operating meme ;Iber or arm 39 andthe parts connected with -.it may not operate, as sometimes occurs by ethe fasteners becoming jammed in the feeding chute, the spring 49. will yield, thus permitting the pitman 44 to move independently of the pin 48. n, a I The reference numeral 50 designates a second oscillating member pivotally secured at its upper end to a lug 51 projecting :from the side of the fastener feeding chute ;24 by means of a screw or equivalent pivot 52, and the lower end of which member is ,provided with a hook shaped projection 53 ;adapted to be moved into the path of the ,fasteners as shown in Fig. 4, or out of said gpath so as to be free of the fasteners, as

.shown in Fig, 3. 1 This member is provided @with a'laterally projecting arm 54 at its gupper end which arm is engaged by one end ;of a spring 55, the other end thereof being secured to a fixed abutmentand the tendency ,of which spring is to move the inember 50 into the position shown in Fig. 3 and to hold it 'nor1nally in that position. The projection 53 at the opposite end of the member 50- is provided with a beveledor inclined face 83 adapted to contact with the fastener in' the chute immediately below it when said projection 53 moves into-and across the path of the fasteners, the-object being to positively force or push the fastener below it and insure the movement of the fastener in case it be stopped "or othera wise held against movement in thechutel l;

The oscillating member 50- above referred ;to is provided with an inclined cam surface or shoulder 56 intermediate. its ends which shoulder is engaged bythe pin 43 projecting downwardly from the plate 42, as herein- I before explained. The plate 42 is preferably made to overlie theoscillating. member 50, as shown. in Fig. 3, and upon rotary motion being imparted'to the plate through ftheshaft 40, as above explained, the pin 43 i engagesthe shoulder 56 and forces the lower j the spring 55 as will be understood. The

hook shaped projection 53 of said'member.

toward the right, referring to Figs. 3 and 4, this movement beingfagainst the:tension of lower side of the projection 53 is inclined, as

shown at v56, which inclined surface engages the; prongof the lowermost fastener after it'has been released by downwardmovement u from the position shown inFig. 6 to the of the stop 33 and thereby gives the fastener a positive push as it passes from the lowerv fendof the chute 24 as above described.

When the stop-'33 is in the position shown in Fig. 6 the oscillating'member 50-is' in the position shown in Fig. 3. If now the-oscih dating operating arm .39 .be moved in a downward direction, Fig. 10, through the pitman 44 and spring 49 as hereinbefore explained, the oscillating member-35 is moved position shown inFig. 7,'and the stop 33 thereby moved out'of the pathxofmovement of movement of the fasteners and the upper edge of said projection into Jpositionto engage and' arrestthe downward movement of the fasteners in the ehute, as showninFig.

4, and, as the projection is'moved across the lower end of'the chute the fastener which was released upon thev downward movement of the stop 33 is engaged by the lower inclined edge 56 of the projection and given a positive push toward the lower end of the fastener chute. ,Astheoperating memberor arm'39 is movedfromithe position shown in Fig. -7-to the position shown in: Figs. 6 and 10, the stop 33 is returnedby the action of the spring 38 into a. position to arrest the do'wnward' movement of ,the-

fasteners .in the chute 24, and reachesthe position shown in Fig; 6 about the time that the extremity of the .proj ection j reached the position in which it'is illustrated in Fig.

3 to which position saidQp 'OIjectiOn is returned by the spring 55. 3: wThe fasteners pass fromithe'lower end of the chute 24 onto a receiving table 57 shown in Fig. T 5. and' indicated 1n a conventional manner in F igs. 6 and 7, the lower end of the chute being provided with a foot as shown at 58, Figs; 3 and 4,.whichfits close to the table and forms' one, of two parallel guides], between which the fasteners are 'theanvil' 22. The othervof said guides is shown at 59, Figs. 3 and 4 the same being pivotally supported at 60 upon ablock 61 which block is'in'turn' supported upon asecmoved from the lower endof the chuteronto p ond-block 62 secured to theframeofthe-machine. These guides are spaced apart from v one another as above. explained :to. thereby provide a slot .63 along which the fasteners pass to the; anvil '22, and the 'gui de'59 is pivotally supported in order that it maybe swung aWay-fromthe guide 58 to-thereby 'expose 'the lower discharge endof thechute 24 and permitgfasteners to be removed, should they become jammed at the lower end of the chute; The movable guide 59 is I held in place by means of a pin 79 which iextendsth rough a hole in it and into the block 61 above referred'to.

vThe fastener receiving tablep57 is itself provided with a slot 80, and the-feferencecharacter 64 designates a reciprocating slide movablebetween-the guides 58, 59andthe ,1 forward end of which isadapted to engage each separate fastener as it'reaches the receiving table'and force thesame along the slot 63. and onto the upper end of the'anvil 22, as will be understood from Fig. 5 of the drawing; This slide is provided with a downwardly extending arm 65 which in turn is connected with a reciprocating crossheadj 66 movable suitableguides provided'for it in the block 61- hereinbefore re:

a downwardly extending pin 67 which in turn is engaged by thebifurcated free endof one arm 68 of bell crank lever pivotally secured to the block 62 at 69,the other arm 70 o fsaid lever being operati-vely connected with the arm 30 of the lever 25-hereinbefore referred to" (see Fig. 1) throi' gh'a pitman*" 71, whereby as the lever 25'i's oscillated as herembefore explained reciprocatory 1 mo 'tion isstransrn'itted to the slide 64. The

particular form of the connection intermediate the arm 30 of the lever 25 and the arm v70 of the bell crank? lever is however not: specifically illustrated, as the same formsno part of the invention to which this 'appli Cation relates. a r V -The fasteners are moved by the slide, 64

them the lower'end of the chute 24 into a position between the upper ends of two jaws 72, the lower ends of which jaws are pivotally supportedby a vertically movable jaw carrying member 74 surrounding the anvil 22am held in its "uppermost" position these jaws being forced toward one another the fastener in an upright position with its .head resting upon the anvil 22 after'it has ferre'dto. This cross-head isprovided with f by means of a spring 75, the upper ends of by a spring 76, These jaws thus act to hold illustrated in Fig. 5, in which position it remains until the button contained in the button receiver 21 is attached to the garment, as

hereinbefore explained; it being understood that after .the fastener has been supplied to the anvil the button contained within the button receiver is forced downward by the plunger 17 and through thebutton receiver and. nto engagement with the fastener, the upwardly projecting prong of; which either pierces an imperforate bottom wall-of the button,=.or passes through "a hole .provided therein, after which it is clenched within the hub of the button in a manner well understood by those familiar with the art relating to button attaching machines.

The pivoted guide 59 is provided with an upwardly extending wing or guard 77, and 78 designates a guard secured to the lower end of the fastener chute, the purpose of these elements being to prevent. the garment from coming into engagement with the fastener releasing mechanism when the machine is in use, the guard 78 also assisting in holding the tack or fastener in its up right, position when being forced down:

wardly by the inclined face 56 of the member 50 and avoiding any and all danger of it being forced out of the chute by the action of said member; 7 j

The oscillating lever 25 is so designed, and the location of the roller 28 is such that motion is communicated to said lever throughout the greater part of the upward movement of the connecting rod 18, from which it follows that the, lever 31 which is operated fromthe-lever :25 partakes of an oscillatory.movement substantially in step with themovements of the levers 1.6 and 25. The fastener feeding mechanism comprising in part the oscillating members 35 and 50, however, is operated only as the lever 31 approaches the ends of its movement because of the lost motion between said lever and the pitman 44:, which lost motion results from the fact that the pin tdmoves in a slot d5 of considerablelength, as hereinbefore explained. It therefore follows that the fastener feeding mechanism is ope "ated and moved from the position shown in Fig. 3 to that shown in Fig. 4, and from the position shown in Fig. i to that shown in Fig.

3, very quickly, as these movements occur while the lever Slis moving through short portions only of p its path of movement, which rapid operation of the fastener feeding mechanism is of importance, especially in fast running machines.
