Beit known thatl, FRANKLIN I-I. CHILTON,

` a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Attachments for Machines for Sewing on Buttons, of which the g following is a specification.

The invention relates to improvements in attachments for machines for sewing on buttons; and it consists in the novel features and combinations of parts hereinafter dej scribed, and particularly pointed out in the claims.

I have embodied my invention in theattachment hereinafter described and claimed for application to the presser-foot of the sewing-machine, the said attachment comprising a base-plate, a pair of jaws for feeding the individual buttons to the sewing-point and there holding them while the sewing is taking place, means for operating said jaws, and means for guiding the buttons into position to be taken by said jaws with the holes of the said buttons in proper alinement, whereby said jaws are enabled to remove the buttons one after another and deliver the same to the proper' point below the needle of the sewingmachine.

The attachment made the subject hereof, in addition to the features hereinbefore mentioned,comprisesse veral cooperating features for giving effect to the main parts of the attachment, and these will be fully described hereinafter in connection with the explanation of the construction and operation of the attachment.

The main features of the attachment com-` prise the means for properly guiding the buttons so that the holes or eyes in the same may always he in proper alinement and the means or jaws for taking the buttons one after another and moving them to position below the needle, the said jaws holding said buttons until the entire operation of sewing them upon the fabric has been effected.

In presenting the attachment in this application I have illustrated the same as applied .toa wellknown form and construction ofsewing-machine for sewing on buttons, said attachment being connected with the presser-foot bar, so as to be raised and lowered thereby, and also connected with usual means for shifting the attachment laterally, so that after one pair of eyes or holesI in the buttons have received the proper number of stitches the said attach mentwill move later; ally, (or lengthwise of the sewing-machine head,) so as to bring the other pair of eyes or holes of the button into proper position to re ceive their stitches. The presser-foot bar to which the attachmentis applied has, as usual, a vibratory motion which moves the attachmeut back and forth toward and from the operator, so that the needle may pass from one hole or eye into the other hole or eye of the buttons. The vibratory presser-foot barand the means for moving the button-holding attachment laterallyare well known in this art and are in common use on machines for sewing on buttons. It is also customary in the class of machines to which my invention pertains to employ a stop-motion and proper regulating means for automatically stopping the machine after a definite number of stitches have been sewed through the holes in the buttons. It is customary to so regulate the machines that any required number of stitches of the well-known machines for sewing on buttons the needle is caused to vibrate laterally, so as to pass from one hole of the button into the next adjoining hole thereof, and in machines of this character my attachment would not `vibrate laterally, but only move toward or from the operator, so that after one pair of holes has received the stitches the other pair of holes could be presented to the needle. In the majority of instances, however, the machines for sewing on buttons have needles which do not have any Vibratory mo- V tion, and in such machines it is necessary to vibrate the attachment so that the holes of the butt-on may be delivered to the needle. I illustrate in the accompanying drawings a portion of one of the latter character of machines in which the needle has no vibratory motion, but is employed in connection with a rotary shuttle, and means for moving the IOO with the jaws which hold the button as havf ingfbeen moved toward the operator and to a point below the needle. Fig. 2 is a central vertical section through a portion of the at- ...tachment and-,illustrates more particularly i Y .Y s en,

the'magazine for holdingthe buttons, the guiding means for preserving the holes or veyes of the buttons in proper alinemell', and

one of the jaws for removing the buttons from the lower end of the said magazine and delivering them one after another to the proper position below the sewing-needle. Fig. 3 is a horizontal section through the magazine for holding the buttons, the section being on the dotted line 3 3 of Fig. 2. Fig. 3 is presented to illustrate the two vertical rods which guide the buttons downward through the maga-Zine and keep their holes or eyes in proper alinement. Fig. 4 is a -front side elevation of a portion of the sewing-machine with my attachment applied thereto, the feeding-jaws being illustrated as holding the button below the sewing-needle. Fig. 5 is an enlarged top View of a portion of my attachment 'and shows more particularly the jaws for holding the button during the sewing operation and also the manner of sewing through onepair of the holes of the button. Fig. bis alike view of same, illustrating the position of the button when the attachment has been shifted in order that the other pair of holes in the button may be subjected to the sewing operation. Fig. 7 is a top View of the attachment comprising my invention shown in connection with a part of the sewing-machine, the latter being in sectionon the dotted line 7 7 of Fig. l. Fig. 7 illustrates the parts ofthe attachment in position holding a button preparatory to the sewing of the same. Fig. 8 is a view of a portion of the rear end of the attachment and illustrates more particularly the adjusting-screw for adjusting the rear ends of the arms which carry the buttonclamping jaws, and Fig. 9 is a vertical transverse section of same on the dotted line 9 9 of Fig. 7.

Inthe drawings, 20 denotes the head of a .sewing-machine for sewing on buttons, said machine having the usual rotary shuttle 2l, needle-bar 22, needle 23, and presser-foot bar 24, to which bar 24 the attachment comprising the present invention is secured by means of a lug 25, connected with the frame of the attachment andheld upon said bar 24 between the nuts 26 26, as shown in Fig. 1, said lug 25 being bifurcated, as shown in Figs. 4 and 7, to pass upon said bar 24.

The general frame of the attachment comprises the base-plate 27, supporting all of the operative parts, the standard 28, and brace 29 for sustaining the button holder or magazine 30, and the front plate 3l, to which is pivoted the plate 32, carrying the lug 25, above referred to, said plate 32 being pivotallyT secured upon the screw 33, Fig..7, so as to permit the attachment to yield or turn to a limited extent under and during the lateral movement imparted thereto when it is desired to shift one pair of the holes of the button' from under the needle-bar and move the other pair of holes of said buttoninto position for sewing. v

-Theclamping-jaws for feeding the individual buttons to position below the needle-bar.

and there holding them are designated bythe numerals 34 34, said jaws corresponding with one another and at their facing sides being recessed, as indicated in Figs. 5, 6, and 7, to receive and bind against and hold'down the opposite edges of the button, the latter being indicated at 35. The clamping-jaws 34 are formed with upwardly-extending ears 36 and are secured to the forward ends of the sliderods 37 37 by means of screws 38, which pass through said ears 36 and into said rods 37 and pivotally hold said clamping-jaws 34, the latter being adapted through the medium of the ears 36. to have a turning or pivotal motion upon the said screws 38. The purpose of pivotally securing the clampingjaws 34 is to enable the said jaws to follow the surfaces of the base-plate 27 and also to lie fiat upon the bed-.plate 39 of the machine when at their full forward position, holding the button below the needle-bar 22. The rods 37, carrying the clamping-jaws 34, extend upward toward the rear of the inclined base-plate 27 and pass through the sleeves 40, the upper or rear ends of the said rods 37 being pivotally secured to thethreaded followers 41, mounted upon the adjusting-screw 42, the latter being formed with the right and left hand threads to receive said followers 4l and being provided with the thumb-wheel 43, by which, when desired, said screw 42 may be rotated. The rotation of the screw 42 is tor effecting the adjustment toward or from one another of the upper or rear ends of the said rods 37. The followers or nuts 41 are internally` threaded to engage the threads of the screw 42, and hence when said screw is turned the followersl or nuts 4l will travel toward or from one another in accordance with the direction of the rotation of said screw. The followers 4l are loosely mounted upon the rear rod 44, (shown more clearlyin Fig. 8,) which is formed with the lugs 45, whereby the thumb-wheel 32 is maintained in a central position. The followers 41 and rod 44 travel with the rods 37 during the sliding movement of the latter,

loro

IIO

and the said rods 37 receive their sliding movement by means hereinafter to be described. 'lhe rod 44 in effect carries the rods 37, and through the rod 44 is imparted the force by which the rods 37 receive their movement. The rod 44 prevents the followers or nuts 41 from turning with the screw 42.

Upon the ends of the rod 44 are pivotally mounted the rear ends of the connectingrods 4G 47 which correspond with one another and at their front ends are pivotally connected with the upper ends of the crank-arms 48 49,which also correspond with one another, and at their lower ends are rigidly secured upon the transverse shaft 50, which extends below the base-plate 27 of the attachment, as indicated by the dotted lines in Fig. 7, said shaft 50 being mounted in suitable hearinglugs 5l, as denoted by 4dotted lines in Fig. l. Upon or to the upper end of the crank-arm 48 is secured the knob or handle 52, which is to be graspedV by the hand of the operator when it is desired to impart a sliding movement to the rod 44 and arms 37. The purpose of the connecting-rods 46 47 and crankarms 48 and 49 is to enable the operator by means of the knob or handle 52 to move the rods 37 and through said rods the clampingjaws 34. When the knob or handle 52 is pushed rearwardly, the rods 46 and 47 will be moved correspondingly in a rearward direction and will push the rod 44 rearward,

` said rod 44 under such action pulling the rods 37 and clamping-jaws 34 rearward. When by means of the knob or handle 52 the operator pulls the rods 46 and 47 frontward, said rods will draw the rod 44 with them and said rod 44 will push the rods 37 and clampingjaws 34 frontward to the position in which they are shown in Fig. 7. Upon the crankarm 48 is pivotally secured a bar 53, having at its rear end the slot 54, Fig. 1, which engages a pin or screw 55, carried by the connecting-rod 46, and the purpose of the bar53 is to limit the throw of the rods 46 and 47 and the parts connected therewith. When the rods 4b 47 have reached the limit of their forward throw and brought the clampingjaws 34 into operative position for holding the button for sewing, as shown in Fig. 7, the pin 55 will have reached the front end of the slot 54 and prevent any further motion in that direction of the rods 46 and 47 and clamping-jaws 34, and when the rods 46 and 47 are moved rearward to the full extent desired the pin 55 will reach the rear end of the slot 54 and stop any further rearward motion of the rods 46 and 47 and clamping-jaws 34. The bar 53, having the slot 54, is thus a means for limiting the forward and rearward motion of the clamping-jaws 34, it being necessary to arrest the clamping-jaws 34 at their front position in order that the button may be properly below the needle, and it also being necessary, or at least desirable, that the clamping-jaws 34 may be limited as to their rearward motion, since at the termination of their rearward motion it is desiredthat said jaws shall clamp the lower button in the magazine or button-holder 30 preparatory to moving the same forward at the proper time to the point of sewing.

The sleeves 40 serve to guide lthe rods 37 during their forward-aud-backward sliding motion, and since said rods 37 have a limited oscillat ory motion toward or from one another t he said sleeves are movably secured by screws 56, which pass upward through the slots 57 in the base-plate 27 and into the plates 58, connected with said sleeves40, said sleeves 40 being preferably formed integrally with the plates 58, as shown. 'lhescrews 56 hold 'the plates 58 down against the base-plate 27, but in conjunction with the slots 57 permit said plates 58 to move toward and from one another under and during the oscillatory moy tion of the rods 37. The plates58 have downwardly-extending ears 59 at their outer edges, said ears turning downward at the sides of the base-plate 27, as more clearly shown in Figs. l and 9, and being connected by the spring 60, wltichimparts, through said ears 59, to the plates 58, sleeves 40, and rods 37 a yielding tension toward one another. The extent of the movement of the plates 58 toward one another may be regulated at will by means of the set-screws 6i, which extend through the ears 59 and contact with the outer vertical edges of the base plate 27. The points of the screws l serve as stops, contacting with the edges of the base-plate 27 to prevent undue movement toward one another of the plates 58 and sleeves 40. VSince the attachment is intended to handle buttons varying` in size, the rods 37, plates 58, and followers 4l are made capable of adjustment to adapt the attachment for buttons varying in size. The followers 4l, as above described, maybe correspondingly adjusted hy means of the screw 42, and from the description hereinhefore presented it will be seen that the plates 58, carrying the sleeves 40, may be adjusted by means of the screws 6l. The screws 61 will preferably be provided with jam-nuts 62, of wellvknown form, for the purpose of locking the screws (5l in set position.

From the description hereinafter presented it will be seen that the main purpose of the spring 60, connecting the plates 58, and through said plates the rods 37, is to cause the clamping-jaws 34 to properly grasp the button at the lower end of the magazine or huttonholder 30 and remove said button. Hence the spring 6U will impart the proper pressure toward oneanother of the clamping-jaws 34 when the latter are to grasp the button. If buttonssmaller in size than the one indicated in Fig. 7 are to be handled by the attachment, the followers 41 would be moved a little nearer toward one another, and the screws 6l would be moved outward correspondingly, so that the plates 58 and rods 37 might normally lie a little closer to one another, and the clampingjaws 34 be thereby brought into such re- IOO upontheforward portion of the base-plate 27 the piVotedpresser-arms 63 63,` which, as illustrated'in- Fig. 7, are secured to the base-plate 27 by means of the screws 64, and thence extend forwardly ofv said base-plate to a positionv permitting them to engage the outer portions of the rods `37. The presser-arms 63 are connected by' a spring 65,\and at their ends the said arms are provided with the'lips 66,which are adapted to extend over thenpper surface ofthe rods 37, and thereby prevent said rods from elevating under any force imparted by the'ascending needle during the operation of sewing. Thespring- 65 imparts a` yielding tension to saidarms 63, pulling them toward oneanother and atl the proper time against thev rods 37, as indicated in`Fig. 7, whereby the clampingjaws 34 are caused to firmlyhold the button 35 during the sewing operation. When the clamping-jaws 34 are at their rearward position adjacentr to the button magazine or holder 30, the presser-arms 63will approach one another to the extent permitted by the adjusting-screws 67, said screws vforming adjustable stops for engaging the edges of the framefot' the attachment and limiting the movement toward one another of the presser-arms 63. When the clampingjaws34 are moving toward their rearward position and the rods 37 recede from the presser-arms'63, the said arms approach'one another, andwhen said jaws, with the button` between them, are movedforward to the point of1 sewing the rounded outer ends otl the rods 37y move against the forward ends of the arms 63 and press them outward in a direction fromone another, whereby said arms'63 are caused to exert pressure against said rods 37 and impart to the clamping-jaws 34 theproper binding action against the button 35. rlhe screws or stops 67 are made adjustable, so as to adapt vthe attachment for buttons varying in size. It ywill beunderstood from what has been said hereinbefore that therearward and forward movements yof the clamping-jaws 34` and rods 37 are effected by manual operation, the operator taking hold of the knob or handle 52 to effect such movements. When the clamping-jaws 34 and rods37 are moved rearward,-they'pass from under the influence ofthevpres'ser-arms 63, but remain under the pressure of the spring 60. The clampingjaws 34 and rods 37 only receivethe pressure of the spring 65 and arms 63 when the rods 37 are'moved to their forward position to enable the jaws 34 to hold the button below the needle-bar. j The button holder or magazine 30 is in th form of a `vertical tube or receptacle adapted to receive a number of the buttons, said butestacasa4 Ltons being placed one upon the other, as in- The holder-3() has'upon its opposite sides trun'nions'68, adapted to pass dicated in Fig. 2.

`Upon the frame 70 is pivotally mounted a frame 7l, havinghooks 72 to pass downward upon and engage the tr'unnions 68 when the latter are in position within the 'said slots 69,

The holder or magazine 30 bears at: its upperportion against a'platelspring 73, whichissecured tothe vupper-end ofthe standard`f28'and the purpose of which will appear hereinafter. vThe lower portion lof' the=holder or magazine 30 is provided atits v'rear side -with aA spring 74, which is secured at its upper endtolthe side of the magazine land at its'lower end is bent under the'magazine to for-m a finger 75,--(seeFig. 2,) which extends kbelow the buttonsandformsa:` yielding support fort-he same: the holder or magazine 3() atits-front side'has a central finger 76, whichi normally extendsl substantially down tothe upper surface of the base-plate 27, andiatits rear-side the said lower endof the holder or magazine 30 has a similar tinger 77. The fingers 76 and 77 serve to retain the button at the lower end ofthe holder orf magazine 30 substantially'in alinement with the buttons in'the upper port-ion of saidholder 30, and the finger 77 s'erves'as` a backing to prevent the bottom button-from being pushed rearward unduly whenthe clamping-jaws 34'recede'rearward and pass against thevsides of the same. The frontl tinger 76 will always prevent the bottomlbutton from moving forward until forcedin that direction by the clampingijaws 3 4. The baseplate 27A, as showny in Fig.` 2, is slightly recessed' to receive theI supporting-finger 75 when thelatteris moved downward bythe act of pulling`- thefbutt'on by means of the jaws 34-fromthe holder130. When the jaws 34, grasping the bottom button, are moved'forward, they will pullfthe lower buttonv against the front finger 76 of the holder 30and turn said holder slightly forward at its lower end to a sufficient extent tol permit the said button to leave-the holder. The forwardvmotion of the lower end of the holder 30 is permitted by reason of the fact'that said holder is mounted upon thev trunnions 68 andthat the upper portion of the saidholder may turn rearwardly againstvthe yielding spring 73. After'the jaws 34, carrying' the bottom but- The frame The lower end of IIO ton, have passed sufficiently forward for the button lo have left the lower end ofthe holder 30 the spring 73, acting against l he upper part of the holder 30, will restore said holder to its normal substantially vertical position shown. The opposite sides of the lower end of the holder 3() are cut away, (thereby formingl the fingers 76 and 77,) so that the jaws 34 may readily pass upon and engage the opposite edges of the bottom button without obstruction. One of the main features of the holder 30 is the employment of the guide-rods 78,u pon which the buttons are strung, as shown in Figs. 2 and 3, and which at their upper ends are connected with a cap 79, fitting the upper end of the holder 30 and prevented from turning axially therein by means of a slight projection 80 thereon entering a recess 81 in the holder, as shown in Fig. l. The projection 8() on the cap79 and the recess 81 in the top of the holder 30 serve also to guide the operator in placing the cap and rods 78 properly7 within the holder-30. In the present instance the buttons shown have four holes or eyes, and hence in the attachment shown Iemploy two of the guiding-rods 78, so that the buttons cannot turn axially within the holder 30 nor get their eyes out. of alinement with one another. The lower ends of the guide-rods 78 are free to permit the escape of the buttons one after another therefrom; but at their upper end said guide-rods are held rigidly by the cap 79. I prefer to till the magazine or holder 30 with buttons when said magazine is detached from its supporting-frame 70, and in carrying out this feature of the operation I remove the cap 79 and guide-rods 78 from t the holder 30 and string the buttons upon said rods 78, and I thereupon slip the holder 30 upon the buttons thus strung upon the rods 78 and then restore the holder containing the buttons and guide-.rods to the supportingframe 70, there locking it by means of the hooks 72. If the buttons to be sewed upon the fabric only possessed two eyes, I could still use the two guide-rods 78, or I could dispose of one of the rods and only use the other rod, since the holder 30 would prevent the buttons from turning axially upon the rod. I regard the employment of the guide or guides engaging the holes of the buttons as one of the important features of my present invention, since by "means thereof the buttons are mechanically guided to the clamping-jaws, by which they are removed to the point of sewing, and this portion ofV my invention is not limited to the special details of the construction described. and shown.

Operation: The operation of the attachmentI hereinbefore described will in large measure be understood from the explanation already given. The attachment will be secured in the machine presented to the presserfoot bar 24, and in the usualmanner said bar 24 will be raised and lowered by the foottreadle (not shown) in order that the fabric r work` may be inserted and removed from below it at will. It may be assumedfor purposes of explanation that the fabric has been placed below the attachment and that the presser-foot 24, carrying the attachment, has been lowered thereupon. The operator will then by means of the knob or handle 52 move the` rods 46 47 and rods 37, with their intermediate connections, rearward in order that the clamping-jaws 34 may be carried upon the opposite sides of the bottom. button in theholder or magazine 30. When the jaws 34 reach said button, the butt-on will force said jaws apart, and said jaws will be caused to bind against the button by reason of the spring 60 connecting the plates 58 and exerting its pressure against the rods 37. After the jaws 34 have passed upon the bottom button the operator will then reverse the motion of the knob or handle 52 and rods 37, and thereby cause the clamping-jaws 34 to move frontward to a point below the sewing-needle, said jaws 34Aduring this motion pulling the button then between them out fr-om the lower end of the holder or magazine and carrying the same to proper position below the needle-bar. After the jaws 34 have carried the button 35 below the needle-bar to the position shown in Pig. 7 the operator will then by pressing on the proper foot-treadle (not shown) set the machine in motion. The machine having been setin motion, the needle will then operate to sew through one pair of the holes ot' the button, as shown in Fig. 5, the presser-foot bar 24 and the button-holding attachment in its entirety being vibrated in the usual manner with this class of machines, so that the needle will first descend through one of said holes and then through` the other thereof and then down through the first hole until the proper number of stitches have been formod,whereupon the attachment will be moved laterally ot' itself, but longitudinally of the base-plate of the sewing-machine, so as to bring the other pair of holes of the button into position to be sewed through by the needle, the attachment and presserfoot bar again vibrating so that the needle may, as before, pass from one hole to another until the proper number of stitches have been formed, as illustrated in Fig. 6. After the stitches have been formed in the requisite number the machine will automatically stop, and the operator, elevating the presser-foot bar, will by pulling on the fabric to which the button has been sewed pull the button from the clamping-jaws 34 and move the fabric along to the next point at which the button is to be sewed. The operator will then repeat the above-described operation, lowering the attachment upon the fabric or work, moving the jaws 34 rearward to clasp another button and then frontward to transport the button to the fabric, and then again set the machine in motion for sewing` on the additional button. This operation will be continued until all of the buttons in the holder 30 have been sewed upon the fabric, and then the op- IDO erator will remove the holder 30 and refill the same and restore it to the attachment, whereuponthe work of sewing on the buttons may be continued.

The operator may be supplied with a number of holders 30, all filled with the buttons, so that she maypot have to stop her work to fill the one holder 30 every time it becomes emptied. It will be seen that the fingers of the operator are not'required for adjusting or holding the buttons, the mechanism described rendering it entirely convenient to operate the jaws by means of the knob or handle 52 to take the buttons one after another from the holder 30 and transport them in proper position below the sewing-needle, said jaws firmly holding the button during the sewing operation.A rIhe means for effecting the lateral vibration of the attachment so that after one pair of the holes in the button have been sewed the other pair may be presented to the needle are well known in this art, and in Figs. 4 and 7 I illustrate the' usual connecting-rod 85; through which the vibratory motion is communicated to the attach ment, said rod 85 being pivotally secured to the attachment at one end and at the other end being connected with the usual mechanism of the sewing-machine for moving it after the correct number of stitches have been sewed through one pair of the holes of the button. A

The sewing-machine illustrated is a wellknown type of machine both as to its vibratory presser-foot bar 24 and vibratory connection 85. The attachment is not, however, limited to the character of machine shown, since in the machines in which the needle itself has a vibratory motion for moving from one hole of t-he button to another hole thereof the attachment holding the button will not have to vibrate back and forth for each pair of the holes of the button, but will simply move laterally after one pair of the holes or eyes of the button have been sewed in order to present the other pair of eyes or holes of the button to the needle. In the event of the buttons only having two holes andthe sewing-machine having the vibratory needle it will not be necessary that the attachment have any vibratory motion either laterally or longitudinally, since in that event the vibratory needle will pass through the two eyes of the stationary button, the latter being held by the clamping-jaws 34. Thus it will be seen that the invention is not confined to any special typeof machine for sewing on buttons, but is meant for application to any inachine for sewing on buttons, the purpose of the attachment being to properly feed the buttons to the sewing-point and there securely hold them. One of the most important objects attained by my invention is t-he proper supplying of the buttons to the clamping-jaws in a manner to` insure the holes or eyes of the buttons coming into proper position to receive the needle, and'iu accordance with my invention the buttons are guided by means which engage the buttons and prevent them from shiftingor carrying their eyes out of' proper alinement. In accordance with my invention the buttons are positively guided to the point where they are taken by the clamping-jaws and are held until the clam ping-jaws take them and move them without change as to the position of the eyes or holes to the point where the buttons are to be sewed upon the fabric. While the holder 30 is substantially in a vertical positionit. inclines slightly,'so that its lower end projects slightly forward of its upper end, aud thus the front edge of' the buttons they reach the lower end of the holder may ltilt downward, as shown in Fig. 2, so as to come into alinement with the facing sides of theclamping-jawst. Whenbuttonshaving only two holes are to be sewed upon the fabric, both of the guiding-rods 78 may be employed, or only one of the said rods may be employed, and likewise when buttons having four holes are to be sewed upon the fabric both of the guiding-rods 78, or only one of the said rods, may be employed, since when only one rod isemployed, it being out of central alinement through the buttons, the latter are prevented from turning axially about said rod by reason of the contact of the edges of the buttons with the walls of the holder 30. The holder 30 is shown as being in the form of a tube with all of its sides fully closed; but it is obvious that the tube may be slotted or made in the form of an open frame in order that the operator may see the buttons and determine what quantity of buttons are' left in the tube at any special time. The holder 30 is useful in guiding the edges of the buttons, especially when only one rod or guide 78 is employed; but when two rods 78 are employed for passing through the pairof holes of the button the said rods alone will .serve to keep the buttons with their holes in alinement with one another. I recommend, however, that some form of holder 30 be em ployedV to engage the exterior edges of the buttons, since thereby less danger of accident or the disarrangement of the buttons is incurred.

In the machine shown the means for operating the presser-foot bar 24 to vibrate the attachment comprise the pivoted forked lever 100, which at its lower end is connected with,

said bar 24 and at its upper end receives and isoscillated by the cam 101.,
