  • the trough 85 is the moreessential factor in compelling the buttons to turn laterally; but the guard-plate 86 aids in this operation, since it prevents the buttons from rapidly rolling down the trough 85.
  • the guard-plate 86 also serves to checkk any impetus that the escaping button may attain and compels said button to fall uponthe base-plate 27 with alimited degree ot' force, whereby said ⁇ button isv enabled to pass to its position between the arms 54 54.

It may be assumed for purposes of explanation that the fabric has been placed below the attachment and that the presser-foot bar 24, carrying the attachment, has been lowered upon said fabric.
  • the said button and chuck will nevertheless be rotated by means of the segment 50, so as to bring the holes or veyes of the button into the proper predetermined position. If, however, when the lever 4l is moved rearward the studs 48 of the chuck 42 should simply press upon the upper surface of the button without at once entering the eyes thereof, the chuck 42 will be at once rotated by means of the segment 50, as above described, and this rotation of the chuck will cause the lower ends of the studs 48 to find and enter the eyes or holes of the button.
  • the button In the absence of the yielding part 49 pressing on the chuck 42 the button would be gripped between the then rigid studs 48 and base-plate 27 and under the pressure of the operators hand on the lever 4l might rotate with the 'chuck without the studs 48 entering the eyes or holes of the button, and under this condition the eyes or holes of the button will not have been given by means of the chuck the proper predetermined position for the sewing operation, nor would the studs 48 have entered the eyes or holes of the button. I therefore regard the yielding chuck 42 as of importance in carrying out in the most successful way the purposes of the invention.
  • the needle will then operate to sew through one pair of holes or eyes of the button in a well-known manner, the presserfoot bar 24 and the button-holder 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 the said holes and then through the other thereof and then down through the first hole until the proper number of stitches have been formed, whereupon the attachment will be moved laterally of itself, but longitudinally of t-he 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 presser-foot 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.
  • the machine will automatically stop, and the operator, raising the presserfoot 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 a button is to be sewed.
  • the operator will then repeat the above-described operation,lower ing the attachment upon the fabric or work and by means of the lever 4l drawing another button to the point of sewing between the jaws 34, whereupon the machine will be again set in motion for sewing on the additional button.
  • buttons in the holder or magazine 29 have been sewed upon the fabric, whereupon the said holder or magazine 29 will be refilled by placing the ⁇ buttons upon the inclined chute 64 and allowing the same to slide down into the said holder or magazine, the work of sewing on the buttons then being conitnued.
  • the fingers of the operator are not required for adjusting or holding the buttons, the mechanism described rendering it entirely convenient to move and properly aline the buttons one after another by means of the lever 41, said lever with each movement thereof to the front carrying the button with its holes or eyes in proper sewing position to the point of sewing between the jaws 34 34, which hold the button during the sewing operation.

SPECIFICATION forming part of Letters Patent No. 685,815, dated November 1901.
Application tiled December 24, 1900. Serial No. 40,866. (No model-J f To all whom t may ooit-cern:
Beit known that I, FRANKLIN H. CHILTON,
. a citizen of the United States, and a resident attachments for machines for sewing on buttons; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.
I have embodied my invention in the attachment hereinafter described and claimed for application to the presser-foot bar of a sewing-machine, the said attachment comprising a base-plate, a magazine for holding a number of the buttons which are to be manually placed therein so that they shall stand on Aedge Ywith their top sides facing outward, means for permitting the buttons to feed, one after another, outward from said magazine, means for preserving the adjusted position of the buttons while they are carried, one after another, from said magazine, so as to cause them when arriving upon the baseplate of the attachment to present themselves with theirtop side uppermost, means for fee'dfiug said buttons, one after another, to the proper point below the needle of the sewingmachine and compelling said buttons to present their eyes or holes in proper position to receive the sewing-needle, and jaws for holding said buttons during the sewing operation.
The attachment made the subject vhereof, in addition to the features hereinbefore mentioned,comprises several coperatingfeatures 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 comprise the receptacle for holding a quantity of the buttons and permitting them to feed outward, one after another, upon the base-plate of the attachment, the means for effecting the delivery of the buttons, one after another, from said base-plate to the point below the needle of the sewingmachine and compelling the holes of the said buttons to present themselves in proper poattachment being connected with the presserfoot 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 orholes vin the buttons have received the proper number of stitches the said attachment may move laterally, (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 receive their stitches. The presser-foot bar, to which the attachment is applied, has, as usual, a vibratory motion, which moves the attachment 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 bar and the means for moving` the button-holding attachment laterally are 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 ofstitches have been sewed through the holes in the buttons. It is customary to so' regulate the machines that any number of stitches 'may be sewed through the holes of the buttons before the machine is automatically stopped, and in the present instance I contemplate the sewing of five stitches through each pair of buttonholes preparatory to the automatic stoppage of the machine.. In some of the well-known machines for sewing on buttons the needle is caused to vibrate laterally, so as to pass from one hole ofthe button into the next adjoining hole thereof, and in the machines of this character my attachment would not vibratelaterally but only move toward or from the operatoigso that after one pair of holes has received the stitches the other pair of holes can be presented to the needle. In the majority of instances,however, machines forsewing IOO on buttons have needles which do not have any vibratory motion, and in such machines it is necessary to vibrate the attachment, so-that the holes of the button may be delivered to broken away and partly in section, of a usual type of sewing-machine for sewing onl buttons with my attachment applied tothe presser-foot bar thereof, and in this iigure the attachment comprising my invention is shown with the means which feed the buttons to the sewing position below the needle and rotate the button to compel the latter to present its holes in proper position as having been moved towardthe operator. Fig. 2 is a horizontal section through a portion of the attachment on the dotted line 2 2 of Fig. 1. Fig. 3 is a front side elevation of a portion of the sewing-machine with my attachment applied thereto. Fig. 4 is a detached side elevation, partly broken away,` of the attachment, this figure showing one side of the attachment, while the other side thereof is illustrated in Fig. l. Fig. 5 is a top view of a portion of the sewing-machine with my attachment applied thereto, the presser-foot bar of the sewing-machine being in section. Fig. 6 is a sectional view through the attachment on the dotted line 6 6 of Fig. l. Fig. 7 is a bottom view of a portion of the attachment and shows the jaws holding the button in position to be sewed upon the fabric. Fig. S is a bottom view of a portion of the lever and rotary chuck by which the buttons are caused to be moved to the point of sewing and their eyes or holes placed'in properv position to receive' the needle, the chuck in this instance being shown as having two studs for engaging the holes in the bar-button-that is, a button having a bar at its center and one' large hole on each side of said bar. 9 is a like view of same, but showing the chuck as having four studs to enter'the four holes of the usual four-hole button, such as shown in Fig. 1. Fig. 10 is a longitudinal section of same on the dotted line 10 10 of Fig.` 9. Fig. 11 is a detached top view of one of the jaws which engage the buttons as they pass to the bed-plate from the magazine or button-holder and retain the same preparatory to the removal of the buttons to the point of sewing. Fig. l2 is a detached perspective View of the chuck having the four studs on itsv lower end to engage the four eyes or holes Fig.
y ofthe button, and Fig. 13 is a like View of the chuck shown as having two studs on its lower end to engage the two holes of a barbutton. Y
In the drawings, 2O denotes the head of a sewing-machine for sewing onv buttons, said machine having the usual rotary shuttle 21, 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 and held upon said bar24 between the nuts 26 26, as shown in Fig..1, said lug 25 being bifurcated, as shown in Fig. 5, to pass upon said bar 24.
1s Y Y 'Y The general frame of the attachment comprises the base-plate 27 supporting all of the operative parts, the bracket 28, Figs. 1 and 4, secured to the upper surface and towardl f one edge of the base-plate 27, the buttonholder or magazine 29, which is secured to the bracket 28 by means of the screws 30, Fig. 4, and the front plate 31, to which is pivoted the plate 32, carrying the lug 25, above referred to, said plate`32 being pivotally secured upon the screw 33, Fig. 5,VY 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 button in toposition below said bar for sewing.
The clamping-jaws for holding the individual buttons in position below the needle-bar are designated by the numerals 34 34, which correspond with one another and are pivotally secured to the lower surface of the vbase-plate 27 by means of the screws 35 35, Fig. 7, and the said jaws 34 34 at the inner or shank ends are formed with the rack-teeth 36 36,'whereby said jaws 34 34, being in mesh with eachother through the medium of the sa'id rack-teeth 36, are compelled to have a uniform andv simultaneous motion. The jaws 34 34 are given a normal spring tension toward one another at their outer or front ends by means of a spring 37, as shown in Fig. 7, said spring engaging no Y both of' the jaws 34 and pressing their outer 'A or front ends toward one another.
whnethe 1 inner or shank ends of the jaws f34 are'secured to the lower side of the base-plate 27, i
the outer or front portions of saidjaws,'which extend frontward beyond the front edge ofV V the base-plate 27, are above a thin yielding metal plate 38, which is secured to the lower-V surface of the base -plate 27 V.and extends' 'i frontward beyond the front edge of the-said plate 27, where said plate 38 is formed with the recess 39,"over which the button to be opshown in Fig. 7.
Verated on by the .sewing-needlefis held, asf` The upper surfacesof the plates 40 40 are curved upwardly, so as to permit a button to pass below them and be moved frontward to a position between the front ends of the jaws 34 34 and directly over the recess 39 in the plate 3S. At their front ends the plates 40 40 norm ally overlap the edges of the button, which may be held between the front ends of the jaws 34 34, .so as to hold the button flat upon the fabric and prevent the operation of the sewing-needle from pulling the button upward, as well as to prevent any accidental displacement of the button, the button being held upon the fabric and within the recess 39 of the plate 38 by means of the jaws 34 34 and the plates 40 40. The front ends of the jaws 34 34 engage the opposite edges of the button and hold the same upon the thin yielding spring-metal plate 38, so that while the main body of the button shall be exposed through the recess 39 of said plate 38 the opposite side edges of the button will rest upon the upper surface of the plate 3S at the opposite edges of the said recess 39. The facing front edges of the plates 40 40 overlap the opposite edges of the button held between the jaws 34, and thus the plates 40, together with the jaws 34 and plate 3S, elfectually hold the button during the sewing operation. Since, however, the jaws 34 are pivoted and have a spring tension toward one another, and since the recess 39 of the plate 38 is open at its front side, the button, after having been sewed upon the fabric, may by pulling on the fabric be withdrawn from between the jaws 34. The base-plate 27 has an inclined position, as shown in Fig. 1; but the front portions of the jaws 34 and plate 38 have substantially a horizontal position, so that the button held by said jaws and below the needlebar may take a substantially flat or horizontal position upon the fabric.- The plate 38 is of thin yielding metal, so that its front portion may yield to the irregularities of the buttons and also to the irregularities of the fabric to be fed to the machine, thereby the more assuredly to effect the proper relation ot the button to the fabric.
The jaws 34 are opened to receive the lbutton between their front or outer ends simply by the pressure effected by the side edges of the button when it is moved frontward to position between the front ends of said jaws. The means for moving the buttons frontward to position between the front ends of the jaws 34 are the lever 41 and chuck 42, the lever 41 being provided at one end with the handle 43 and at its other end having a universaljoint connection with an arm 44, Fig. 5, extending outward troin the body of the attachment, said universal-joint connection consisting of the vertical pivot 45, carried by the arm 44,and the horizontal pin 4G,which passes through the lever 41 and pin 45. The pivotpin 45 enables the operator to impart to the lever 41 an oscillatory motion in a horizontal direction, and the pin 46 enables the operator to impart an up-and-down motion to the handle end of said klever 41. The chuck 42,
carried by the lever 4l, is shown in detailin Figs. 12 and 13, and consists of a body portion set within an aperture in the lever 41 and having at its upper end a pinion-wheel 47 and at its lower end the proper number of studs 48 to engage the eyes of the button. The studs 48 project downward below the lower surface of the lever 41, as shown in Fig. 10, and the pinion-wheel 47 bears upon the upper surface of said lever 4l and prevents the chuck from passing 'unduly downward through said lever. The chuck 42 is yieldingly held within its aperture in the lever 41 by means of a leaf-spring 49, which is fastened at one end to the lever41 and at its other end bears upon the small stud at the center of the upper surface of the pinion-wheel 47, as clearly illustrated in Figs. 5 and 10. The spring 49 exerts a constant tension downward on the chuck 42; but it is to be observed that said spring will yield upward with the chuck 42 when during the feeding of the buttons said upward yielding of the chuck becomes necessary, as hereinafter explained. The chuck 42 has two functions to perform, one being to engage the eyes of the button when the button is in the exposed position illustrated in Fig. 6 and move the button on the path of the dotted line shown in Fig. 6 to a position below the needle-bar, in which position the chuck 42 is shown in Fig. 6, and the second function being when it has engaged the button to perform a rotary motion, so as to compel the eyes ot' the but IOO ton to be properly presented for the reception of the stitches. The lever 41 will be moved by hand, as hereinafter explained, for the purpose of causing the studs 48 of the chuck 42 to engage the eyes of the button resting on the base-plate 27, as shown in Fig. 6, and compelling the travel of the button to its position for sewing below the needle-bar of the machine, and the rotary motion of the chuck 42 for securing the proper alineinent of the eyes of the button for the sewing will be effected manually by the operator. The fact that the end of the lever 41 has a universaljoint connection with the arm 44, as above described, enables the operator to move the said lever from its extreme front position (shown in Fig. 6 by full lines) to its extreme rear position, (shown in Fig. 6 bydotted lines,) so that the chuck 42 may pass rearward to engage the holes in the button then resting on the base-plate 27, and during this rearward motion of the lever 41 to the position in which it is illustrated by dotted lines in Fig. 6 the lever 41 will be turned upward slightly, so that the lower ends of the studs 48 of the chuck 42 may be lowered directly upon the upper surface of the but-ton. The horizontal movement t-o be imparted to the lever 41by the operator is, in part, to enable the chuck- 42 to reach the button then exposed on the base-plate 27 and move the button to its position for sewing below the needle-bar, and
IIO
the up-and-down motion which the lever 4l is permitted to have is to enable the studs 48 of the chuck 42 to in an unobstructed manner be placed directly upon the upper surface of the said exposed button preparatory to engaging the eyes or holesof the latter, and thereby grip the same so that during the forward movement of the lever 4l it will move the button to its front position below the needle-bar. The engagement of the studs 48 of the chuck 42 with the eyes or holes of 'the exposed button on the base-plate 27, Fig. 6, constitutes the hold which the lever 4l has upon the button to compel the forward movement of the latter to position between the front ends of the jaws 34, said button when passing between the front ends of the jaws 34 moving the latter outward from one another against the stress of the spring 37, and when the button is first engaged by the studs 48 it is given a rotary motion to effect the proper alinement of its holes or eyes by means of the chuck 42 and segment 50, which segment is pivoted upon the upper surface of the lever 4l and engages the pinion-wheel 47 on the upper end of the chuck 42. The segment 50 is provided with a thumb-piece or handle 5l for the convenient manual operation of the segment, and the handle or thumb-piece 5l has iiexed against it a spring 52, which imparts to the segment 50 its normal position, (shown in Fig. 5,) one end of the segment being in engagement with the pinion-wheel 47,
leaving the remainder of the segment 50 to be moved against the pinion-wheel 47 for the purpose of rotating the chuck 42 and through the studs 48 the button held by said chuck. If the buttons when they are one after another exposed upon the base plate 27, as shown in Fig. 6, would always present their eyes or holes in proper position for sewing and in proper position to be engaged by the studs 48, it would not be necessary to provide means for rotating the chuck 42; but since the buttons will present themselves with their eyes or holes invarious positions' it is necessary that the chuck 42 be made capable of rotation, and hence I-provide the segment 50 and handle 51, so that the operator may rotate the chuck 42 to elect the engagement of the studs 48 with the eyes or holes of the button and compel the rotation of the button in order to bring the holes or eyes of the latter into properposition with respect to the sewing-machineneedle. The studs 48 will correspond in number with the eyes or holes in the button, and they will be of a diameter permitting them to enter the holes or eyes of the button, and the timing and position of the chuck 42 are such that when the handle portion 5l of the segment 50 is pressed against the movement frontwar'do'f' tlie lever 4l Vand the then upward and rearward movement ofi tion (shown by dottedlines in Fig. 6) has moved the segment 50 so as to secure lthe proper position of the eyes or holes of the button she will continue the pressure of herY thumb upon the handle 51 ot the segment 50 until after she has moved the lever 4l and button to their front position below the needle? bar and has lifted the lever 4l and Ystuds 48f V 'y V j Y from the button, and thereupon she will release the segment 50,50 that the spring 52'mayl .Y move the same toits normal position, (shown Y Y Y in Fig. 5,) the operator simultaneouslywith the releasing of the segment 50 moving the Y di;
lever 4l rearward to the positionin` which it is shown by dotted lines in Fig. 6, so thatiit may be out of the way of the needle 23 and Y be pnt into position to engage the next button exposed upon the base-plate Y27. lVith each frontward movement of the lever 4l from the position in which it is shown by dotted lines in Fig. 6 to the position in which f Y it is shown by full lines in Fig. 6 one button will be allowed to pass from the magazine or holder 29 to the position upon the base-plate 27 in which'it is shown in Fig. 6, and'withV each frontward movement of the lever 4l Y. 'Y
from the position in which it is shown by dotred nues in Fig. 6 no the position in which it is shown by full lines in Fig. 6 the-chuck 42 will carry a button from the positionin which the button is shown in Fig. 6 to the'point otr).

At this place it seems roo l. 'Y
13251 fifi' appropriate to refer to the lever-armsrr54 54, (shownin Fig. 6,)-since said arms catch the button as it falls upon'the base-plate 27 and retain the same in positionV for it to be'engaged by the chuck 42 when the lever 4l is moved 'Y rearward. The lever-arms54 54 are pivotally'V Y l secured upon the upper surface ofthe basev to normally close together at their front ends, V as shown in Fig. 6, by means of a spring 55, .Y which by pulling on one ot'V the Varms l54 eff fects the closing movement of the said arms, this being dueto the fact that the shankends.

the base-plate 27 and be held preparatory to its removal by the chuck 42, Acarried `by the Q l;l
lever 4l. The inner or facing edges of the lever-arms 54 54 constitute converging guid; ing-surfaces to direct the button to the posi lisif tion in which it is shown in Fig. 6, where it will be seen that the button is at the point of juncture between the front ends of said arm 54. lVhen the chuck 42 engages the button and moves frontward with the lever 41, the pressing of the button against the converging ends of the lever-arms 54 54 will cause said arms to open outward and permit the escape of the button between said ends, said button taking the path indicated by the curved dotted line in Fig. 6. The lever-arms 5i 54 are not connected with any of the moving parts of the attachment, but are simply pivoted to the base-plate 27, and are given a normal closed position (shown in Fig. 6) by means of the spring 55.
The buttons to be sewed upon the fabric are held within the button holder or magazine 29 and are one after another permitted to escape from said holder or magazine 29 with each movement to the front of the lever 4l. The button holder or magazine 29 is'comprised in the main of the vertical sides 6l., the latter being preferably of glass or transparent material and the formerbeing.
of metal and having vertical edge tlanges 62 63, Fig. 2, to form the ends of the magazine or holder. At its upper edge the plate 60, forming one side of the magazine or holder 29, is extended laterally on an inclined line, as shown in Figs. l and 4, to form a chute 64, which inclines downward to a point slightly below the upper edge of the glass or transparant side plate 6l, and the buttons to be fed to the magazine or holder 29 are placed upon the chute 6I with theirtop surface uppermost and allowed to slide down the same andinto the space between the sides 60 6l of the said holder-,so that said buttons may reach the position in which they are illustrated in Fig. l. The space between the plates 60 6l should be so regulated as to simply freely receive the buttons without permitting the buttons to get into tilted positions or overlap one another at their edges, it being my purpose that all of the buttons within the holder or magazine 29 `shall stand on edge in a single layer and be incapable of overlapping one another at their edges. I prefer that the side plate (Sl-be transparent in order that the operator may observe the buttons and know when the magazine or holder requires relilling. In order to adjust the side plate 6l in accordance with the thickness of the buttons, I provide the adjusting-screws 65, which bear against the plate 6l and may be employed for moving the plate 6l inward against the felt packing-strip 66, Fig. 2, although I do not regard the employment of the screws 65 as important, since various usual mechanical means will suggest themselves for regulating the width of the space between the plates 60 61 of the magazine 29. The magazine or holder 29 is open at its upper end to receive the buttons and atits lower end is closed by a bottom plate 67. The rear end 'of the magazine 29 is entirely closed by the ange 62, and the front end of the magazine 29 is entirely closed by the flange 63, with the eX- ception of the vertically-elongated opening 68, formed in said liange 63 at the lower front end of the said magazine, as shown in Fig. l. Above the elongated opening 68, through which the buttons at the proper time escape-,is provided an adjustable guard 69, which defines a space at the front lower end of the magazine 29 for the reception of an individual button, said guard 69 being made adjustable by means of the nut 70, so as to enable the varying of said space in accordance with the diameter of the button. To the lower surface of the bottom 67 of the magazine 29 is secured the leaf-spring 71, carrying at its front portiona tooth 72, adapted to be moved upward or downward within aslot provided to receive it at the' front end of the bottom plate 67 of the magazine 29. The front end of the spring 7l turns upward, as shown in Fig. l, to form an arm 73, disposed in the front of the elongated opening 68, through which the buttons escape from the magazine 29. This arm 73 contains an elongated opening corresponding with the opening 68, and when said arm 73 is in its upper position (shown in Fig. l) the button then below the guard 69 may freely pass outward through the said elongated opening in the arm 73 and find its way to the base-plate 27 in the position in which the exposed button is shown in Fig. 6. It is to be observed, however, that when the arm 73 is in its upper position (shown in Fig. l) the tooth 72, connected with the spring 71, is also in its upper position, engaging the next button to the one which has escaped and operating to prevent any of the buttons from following down the bottom plate 67 to the elongated exit-opening 68. When the front portion of the spring 7l is allowed to lower from the position in which it is shown in Fig. l, the tooth 72 is relieved from the buttons, and the arm 73 carries its elongated opening from a position in alinement with the opening 68,'and hence at such time another button may pass down the inclined bottom 67 of the magazine 29 and find its position below the guard 69 and at the ent-rance to the exit-aperture 68, said button being prevented from passing throughthe exit-aperture 68 by reason of the fact that a solid portion oflthe arm 73 partly closes the elongated opening 68. 'lh us the arm 73 when in its lower position prevents the escape of the buttons through the exit-opening 68 and when in its upper position does permitthe escape of a button through the opening 68 and the opening in itself, (said arm 73,) while at the same time when the arm 73 is in its upper position the tooth 72 is alsoin its upper position, and said tooth'prevents the escape of more than one button through said exit-opening 68 and the corresponding opening in said arm '73. The opening in the arm 73 is numbered 74 and is shown in Fig. 6. The means for acting upon the spring 7l to IOO IIO
compel it to move in its upper position (shown in Fig. 1) consistssimply of an arm 75, which extends horizontally below the said spring 71 from the lower end of the pivoted arm 76, Fig. 4, which arm 76 has adjacent to its lower end the vertical blade 77,in engagement at its lower end with an arm 78, Fig.2 carried by the rod 79, whose front end is pivotally secured to the lever 41, so as to be reciprocated by said lever 41 during the frontward and rearward motions of the latter. When the lever 41 is in its front position, (shown by full lines in Figs. 5 and 6,) the horizontal arm 75, connected with the pivoted arm 76, will be in the position in which it is shown in Fig. 1, holding the spring 7l up against the bottom plate 67 ot' the magazine or holder 29, and when the lever 4l is pushed to its position shown bydotted lines in Fig. 6 the rod 79 and its arm 78 will by acting on the blade 77 move the lower end of the arm 76, together with the horizontal arm 75, rearward, so as to free said arm from acting against the spring 71 and permit the said spring of its own tension to turn downward for the purpose of carrying the tooth 72 from contact with the buttons andV lowering the arm 73, so thatit may obstruct the exit-open ing 68. Thus during the rearward motion of the lever 41 the button previously held by the tooth 72, as shown in Fig. l, is freed to pass below the guard 69 and to theAeXit-opening 68, but is prevented from escapingthrough said opening 68 by reason ofthe obstruction' furnished by the vertical arm 73. \Vhen the lever 41 is moved to itsl front position, (shown by full lines in Fig. 6,) it, aciiugthrough the rod 79, arm 78, blade 77, andpivot-.arm 76, will pull the horizontal arm 75 frontward against the spring 71 and cause said spring to move to its upper position, (shown in Fig. 1,) whereby the tooth 72 willv be caused to check any movement of the second button to the lower end in the magazine'29, and the vertical arm' 73 will permit the escape of the last button'in the'magazine 29, said button of its own gravity passing through the elongated opening 68 and the corresponding elongated opening 74 in said arm 73. It will thus be observed that with each frontward motion of the lever 41 a button is permitted to escape from the magazine 29 and tinds its way to the position in which the exposed vbutton is shown in Fig. 6 and that during each rearward motion of the lever 41 the tooth 72 and arm 73 are permitted to lower, so that another button may lind its position below the guard 69 preparatoiay to escaping on the subsequent frontward motion of the lever 41. It will be understood that with each frontward movement of the lever 41 the button exposed on the base-plate 27 will be carried frontward to the sewing position. The movement of the lever 41, therefore, controls the feed of thebuttons from the magazine or holder 29.
In order to prevent any clogging within the magazine or holder 29, I provide within the magazine the pivoted arm 80, (shown in Fig. 1,) which is pivotally secured at its .up-
per end and at its lower portion is connected with a pin 8l, Fig. 4, connected withthe'piv- Y the engagement of the blade 77 of the said Y arm 76 with the arm 78, connected with the rod 79, and with each movement of the armV 76the upperend of the blade 77 carried thereby will operate to move the lower end of the lever-arm 82, whereby said lever-arm 82, with its pin 8l, is enabled to impart a swinging or oscillatory motion to the agitator-arm 80. The side plate 60 of the magazine or holder 29 is provided with a segmental slot, as shown in Fig. 1, to receive the pin 81 and permit ofV the movement of the said pin with the arlnf 80. The arm is employed simply to prevent the clogging of the buttons and to render it certain that the buttons will feed downward automatically toward the exit-opening 68.
It is desirable that the `buttons as they esing 68 preparatory to taking their place upon the base-plate 27, on which the exposed but- Y.
tou is shown in Fig. 6, shall have their upper side turned uppermost, so that when the button is applied upon the fabric its top side-will be exposed, and to this end Iiprovide upon the lower front end of the magazine 29 a curved trough 85 and also a guard-plate 86. The buttons as they escape fromy the opening 68 pass upon the curved trough 85 and against the guard-plate 86, and the curvature of the trough isV such that when the buttons contact with the guard-plate 86 theyare caused to turned uppermost, and when in this or substantially in this position they fall from the v'end ot the trough 85 upon the base-plate 27.
The trough 85 is the moreessential factor in compelling the buttons to turn laterally; but the guard-plate 86 aids in this operation, since it prevents the buttons from rapidly rolling down the trough 85. The guard-plate 86 also serves to checkk any impetus that the escaping button may attain and compels said button to fall uponthe base-plate 27 with alimited degree ot' force, whereby said `button isv enabled to pass to its position between the arms 54 54. In the absence of some checking `means for the buttons they-might not remain losV . turn laterally on the trough with their top side i 11o I. Y
being drawn unduly frontward, and the purpose of the stopping of the lever 4l at the end of its frontward movement being to prevent the operator from drawing the button held by the chuck 42 entirely through the space between the front ends of the clamping-jaws 34 instead of allowing the button to remain between said clamping-jaws until properly sewed upon the fabric.
The operation of employing the attachment hereinbefore described will in large measure be understood from the explanation already given. The attachment will be secured in the machine presented to the presser-foot bar 24, and in the usual manner said bar 24 will be raised and lowered bya foot-treadle (not shown) in order that the fabric or work may be inserted and removed from below it at will. It may be assumed for purposes of explanation that the fabric has been placed below the attachment and that the presser-foot bar 24, carrying the attachment, has been lowered upon said fabric. The operator will then take hold of the handle 43 of the lever 4l and move the saine frontward to effect the elevation of the spring 7l and the escape of a button from the holder or magazine 29, the button passing through the elongated opening (58 and the opening 74 in the arm 73 of said spring 7l. The button escaping from the magazine or holder 29 will pass upon the trough 85 and against the guard-plate 86 and then fall upon the base-plate 27 with its top side uppermost, as shown in Fig. 6, the said button being confined within the space outlined by the lever-arms 54 54. Thereupon the operator will raise the handle end of the lever 4l slightly and move said lever to its rear position (shown b v dotted lines in Fig. 6) and lower the lever 4l, so that the studs 48 of the chuck 42 may pass directly upon the then exposed button on the base-plate 27. As soon as the lower ends of the studs 48 have entered the eyes of the button or have come to a position upon the top of said button, not having entered the eyes thereof, the operator will bypressing on the handle 5l of the segment 50 cause said handle and said segment to move until said handle reaches the stop 53, the purpose of moving said segment 50 being to effect the rotation of the chuck 42 and the button, so that the holesof the eyes of the buttonv may be given aproper predetermined position. If when the lever 4l is moved rearward the studs 48 of the chuck 42 at once enter the eyes or holes of the button, the said button and chuck will nevertheless be rotated by means of the segment 50, so as to bring the holes or veyes of the button into the proper predetermined position. If, however, when the lever 4l is moved rearward the studs 48 of the chuck 42 should simply press upon the upper surface of the button without at once entering the eyes thereof, the chuck 42 will be at once rotated by means of the segment 50, as above described, and this rotation of the chuck will cause the lower ends of the studs 48 to find and enter the eyes or holes of the button. Since it will frequently happen that thelower ends of the studs 48 will not when the lever 4l is moved rearward at once enter the eyes or holes of the button, I have provided the l -studs 48 strike the upper surface of the button the force exerted by the operator on the lever 4l is relieved from the button and the latter will not be so rigidly gripped between the lower ends of the studs 48 and the upper surface of the base-plate 27 to rotate, but will remain substan tiallystationary while the chuck 42 rotates and until the studs 48 enter the eyes -or holes of the button, whereupon the button will rotate with the chuck until the chuck has been given the full limit of its movement. In the absence of the yielding part 49 pressing on the chuck 42 the button would be gripped between the then rigid studs 48 and base-plate 27 and under the pressure of the operators hand on the lever 4l might rotate with the 'chuck without the studs 48 entering the eyes or holes of the button, and under this condition the eyes or holes of the button will not have been given by means of the chuck the proper predetermined position for the sewing operation, nor would the studs 48 have entered the eyes or holes of the button. I therefore regard the yielding chuck 42 as of importance in carrying out in the most successful way the purposes of the invention. After the studs 48 have entered the eyes or holes of the button and the chuck has been rotated to the full limit of its movement (determined by the contact of the handle 5l with the stop 53) the operator will retain her finger upon the handle 5l, so that there may be no reverse motion in the chuck 42, and move the lever 4l to its front position, (shown in Fig. 6,) this frontward movement of the lever 4l compelling the button held by the chuck 42 to open the arms 54 and causing the button to pass between the front ends of the jaws 34 34 and directly over the recess 39 in the yield- Ving plate 38, located at the front end of the base-plate 27. Vhen the button has reached this position between the jaws 34 34, the operator, still pressing with her thumb against the handle 5l of the segment 50, will raise IOC TIO
the lever 4l, so that the studs 48 of the chuck 42 will leave the button, and thereupon she will release the handle 5l and move the lever rearward to engage the next button exposed on the base-plate 27. The button having been left by the lever 4l between the jaws 34 34 in position to be sewed upon the fabric, the operator will then by pressing on the proper foot-treadle (not shown) seit the machine in motion. The machine having been set in motion, the needle will then operate to sew through one pair of holes or eyes of the button in a well-known manner, the presserfoot bar 24 and the button-holder 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 the said holes and then through the other thereof and then down through the first hole until the proper number of stitches have been formed, whereupon the attachment will be moved laterally of itself, but longitudinally of t-he 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 presser-foot 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. After the stitches have been formed in the requisite number the machine will automatically stop, and the operator, raising the presserfoot 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 a button is to be sewed. The operator will then repeat the above-described operation,lower ing the attachment upon the fabric or work and by means of the lever 4l drawing another button to the point of sewing between the jaws 34, whereupon the machine will be again set in motion for sewing on the additional button. This operation will be continued until all of the buttons in the holder or magazine 29 have been sewed upon the fabric, whereupon the said holder or magazine 29 will be refilled by placing the` buttons upon the inclined chute 64 and allowing the same to slide down into the said holder or magazine, the work of sewing on the buttons then being conitnued. 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 move and properly aline the buttons one after another by means of the lever 41, said lever with each movement thereof to the front carrying the button with its holes or eyes in proper sewing position to the point of sewing between the jaws 34 34, which hold the button during the sewing operation. The means for effecting the lateral vibration of the attachment, so that when one pair of 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. 3 and 5 I illustrate the usual connecting-rod 100, through which a vibratory motion is communicated to the attachment, said rod being pivotally secured to the attachment at one end and at the other end being connected with the usual mechanism of sewing-machines for moving it after the correct number of stitches have been sewed through one pair of the holes of the button.
The sewing-machine illustrated is a wellknown type of machine both as to its vibratory presser-foot bar 24 and vibratory connection 100. The attachment is not, however, limited to the character of machine shown,
vibratory motion for moving from one hole Y of the button to the other hole thereof the attachment holding the button willnot have to vibrate back and forth for each pair of holes of the button, but will sim ply 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 and the sewingsfff machine having a vibratory needle it will not Y be necessary that the attachment have any i 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 ai. Thus it will be seen a that the invention is not confined to any'special type of machine for sewing on buttons, but is meant forapplication to any machine for 'sewing on buttons, the purpose of the at'- tachment being to properly feed the buttons to the sewing-point with their holes or eyesl in a proper predetermined position and there securely hold the buttons during the sewing operation. One of the most important objects attained is the proper supplying of the Y buttons to the clamping-jaws 34 in a manner to insure the holes or eyes of the buttons coming into proper position to receive the needle.
The holder or magazine of the construction illustrated is of the greatest advantage in attachments of the character io which my invention relates, since by reason thereof the Y.
buttons are soheld and controlled thatonly ff i one button at a time leaves the holder or magazine, and the holder or magazine may The be quickly recharged with buttons. placing of the buttons on .the chute 64 is a very simple matter, and .when the buttons have been placed on the chute 64 with their top side uppermost the buttons will automatically slide down said chute and find-their zine 29.
. A very important feature of the invention Y* Y resides in the fact that the studs 48 areatga-j the lower side of the rotary chuck 42 andv engage the holes of the button from the upper side of the latter when the button is restrr'j ing at upon the upper surface of the base- ,e 1 'Y plate 27, whereby the button while in process of being engaged bythe chuck has a solidV surface against which it may bear, The chuck 42 is vertically yielding to a limited extent; but the button to be engaged by the y chuck is upon the unyielding fiat base-plate 27. A further important feature enhancing the value andsuccess of the machine is that the base-plate 27 serves as a slideway or raceway for the button from the point at which the chuck 42 engages the button to thepoint 79; Y since in machines in which the needle has a 1 essere at which the chuck leaves the button between the clamping-jaws 34, there being no1 possibilityr under such arrangement for the button to escape from the chuck until after the button reaches its final position and the chuck is directly lifted therefrom. It is of the utmost importance that the button should be held fiat against the base-plate 27 and moved along and in contact with said base-plate by the chuck 42 during the employment of the latter in transferring the button from its first position on the base-plate to its linal position between the clamping-jaws 34.
In the machine shown the means for operating the presser-foot bar 24 to vibrate the attachment comprises a pivoted forked lever 102, Fig. l, which at its lower end is connected with said bar 24 and at its upper end receives and is oscillated by the cam 103.
