SPECIFICATION forming part of Letters Patent No. 298,200, dated May 6, 1884.

Application filed May '15, mm. (no than.)

To all whom it may. concern:

KINS, of Stoneham, and ERASTUS WOOD\VARD,

of Somerville, county of lllli'ddlesex, State of Massachusetts; have invented" an Improve. ment in Button-Setting Machines, of which the following description, in connection with the accompanying; drawings, is a specifica tion, like letters on the drawings representing like parts; v v

--l;his invention has --for its objectthe production of'an automatically-operating machine, whereby separate buttons and separate 'fastenings to secure the buttons to a boot o'r shoe or other article, material, or fabric may .bepresented to the saidboot or shoe-o'rother article'in' correct position to. enable the fast-v eners to-bc automatically driven through the about the eye of the button, so as to secure.

the same to the said article.

In the machine illustrated in the accompanying drawings, as embodying :one practical form of this invention, the buttons are placed in suitable recess or hopper, from which they pass into a button conducting chute or roadway,. along which, to the delivery end of the same, the said buttons travel by reason of their own weight or gravity,- and are finally presented with the flat side of the shank and eye in a predetermined position to enable the said eye to be entered by the point of a fastener, the latter being presented in proper position with relation to the deliveryend of the button-condnctingchute by means of a fastener conductor'or chute. The fasteners employed, as'herein-shown and as will be preferably used,-are composed of tacks having a-single prong andahead; but it is tobe.

understood that anyother'well-known and,

- suitable form of fastencradaptedto bedriveh tor the fasteners arefed, either by jarr 1;; or

er isadapted to be reciprocated gnidewa'ys;

said frame is swung sufficiently far to insure the feeding of the material for the requisite distance to properly space the said buttons,

thus placing them at the proper distance apart. The fastener to be driven, when transferred from the chute into position in line with the driver,is acted upon by the latter; but before the point of the fastener reaches the material the said fastener is made to pass between the jaws of a centering device mounted upon the upper end of a slide-bar, and projected from one side of the latter so as to be in line with the driver, the said centering device acting to guide and direct the point of the fastening device into the exact position desired with relation to the eye of the button-shank and the anvil or clinching-surface. The point of the fastener having been placed under the control of the centering device, thclatter commences to rise in unison with the driver until the upper end of the centering device meets the material, when the said device stops and the driver continues to move and completely drive the fastening, the centering device having yielding jaws, whereby the head of the fastening device may be driven out through the said jaws, the latter being acted upon by suitable springs.

The machine herein described has been provided with means whereby, in case a fastening fails to be presented to the transferrer to be carried from the chute to the driver, the apparatus cannot act to feed the material and remove from the groove of the chute the button which should have been attached at the last operation of the driver, but which was not attached by reason of the failure of a fastener to arrive in proper position opposite the driver.

The main shaft A of the machine, supported in suitable bearings of the frame-work A, has placed looselyupon it a driving-wheel, A the hub of which is provided with an annular groove, a, which receives the fork a of a shipper, A", adapted to slide on. a guide, A, forming part of the main frame A, the said shipper being moved in one direction by the spring A, and in the opposite direction by the cam A", fast on the main shaft A, the side of the said cam working against a pin, A under the control of a treadle, the said cam and spring A operating in conjunction with the pin Ahunder the control of the operator, to insure the engagement of the clutch parts of the pulley and cam to drive the main shaft A, or to disengage the parts and leave the shaft at rest, so that the machine will stop itself automatically, and at a certain definite position of the main shaft whenever the pin A. is permitted to rest. At its opposite end the shaft A has a bevel-gear, B, which engages a bevel-wheel, B, on a vertical shaft, B", having suitable bearings, B", held in hubs a" of a swinging frame, B, by set-screws B. The lower hub' of the swinging frame rests upon a bearing, a", fixed with relation to the main frame A. The top of the gear 3' is provided with a canigroovc, 100, which receives in it a roller or stud at the end of an. arm, B", of a rockershaft, B having snitablebearingsin the framework, and having a second arm, 13*, which is adapted to strike the inclined face 2 of a pro.- jcction, G,0f the feed-controlling device, shown as an elbow-lever, C, having its fulcrum on a bolt, 0", attached to the swinging frame B, the arm 0" of the said elbow-lever being normally held int-he position shown in Fig. 6 by the spring 99, so that the end of the arm (1 rests against the rear end of the detector 1). (Shown best in Fig. 7.) The rock-shaft B and its arms constitute what we shall call the feed-lever, and it has a feed-adjusting device, I)", the position of which on the said feedlever may be varied and"determined by the screws or adjusting devices I) I). The farther the end of the adjusting device I) is from the .from the lower end of the sleeve of thefasten ing-detector b, the said detector being held in place by a screw, which serves as afulcrum for it, the said detector being acted upon by a spring 0', which normally keeps the said finger 6 in the roadway and in .the path of the head of the fastener, and. this detector will be operated, as will hereinafter be described.

The shaft 13 has a cam-hub, D, which receives aroller or stud of the anvil-carrier D,

- (shown as a lever pivoted at D,) the said carrier being provided at its forward end with a suitable groove to receive the anvil D having a clinching-surface, 8, (see Fig. 4,) against which the .end of the tack or fastener strikes and is curved, curled over, or clinched, as represented in Fig. 16, where a fastener and its head are shown in white, the 'said fastener being inserted in the material 10 of a boot or shoe or other article, the button being marked 12. The anvil has .a prong, 9, -to enter the eye of the button-shank, center it, and, as will be hereinafter described, assist in feeding the button out of the guideway of the button chute or conductor The anvil is made longitudinally adjustable in a groove on the. carrier, and abuts at one" end against an adj ustingserew, 13, held in a cap, E, which acts as a clamp to hold the anvil'in place, the said cap being forced down on the anvil by a screw, 14. The carrier D has a link, E attached to it and to a radiusbar, E, pivoted at. E" on apart fthc swinging frame B. The lower end of the said radius-bar is shown as-forked to embrace a block, 16, on a. stud or bolt, 15, thelatter being connected with a dovetailed slide, E", fitted into a dovetailed. groove made in the frame 13. The slide E has attached to it by bolt 17, (see Fig. 7,) in an adjustable manner, the fastener transferrer or carrier F, the forward end of the latter being entered into the groove or way at, before referred to, the said transferrer being provided with a longitudinal slot, 18. (Shown in Fig. 25, and in dotted lines, Fig. 4.) I

The fasteners c, dropped into the receiver or hopper F,'pivoted at F and slotted at its front end at .19, (see Fig, 5,) are permitted to passlout throughthe said slots into the groove 20, having'the ,cross section'shown in that; de-

groove is L shaped, so that the enlarge cular head of the-fastener c is guided horizontal part ot ,the saidgroove, while he; prong part standsin the vertical part'of ,thei groove with its- )oint-'uppermost. The fastf eners travel downalong the, groove 20 of the bare, to which the'driverGis attachedby ferrer F is drawn back) against the ,abutment or wall 23, forming part of the said chute, as

shown by the black dots inFig. 22, which latter in the groove 20 are intended to represent the shanks of the fasteners c.

22,- its end strikes against the edge of the head of the fastener and pushes the said fastener along in the groove or way 4, placing the said head in position just immediately above the As the transferrer is moyed forward from the position, Fig.

driver G, which isfitted into a'slot atfor'near the end of the chute or conductor 1), as shown in Fig. 7. As the transferrer moves'the'fastener, along in the said grooved, the head of the said fastener strikes the finger 6, and-in .its passage beyond the said finger turns it and the detector b about its center 0'', so that the .end 24 thereof extends into the groove in the transferrer F, and the shoulder at the end of the said groove acts to further turnthe detector, so that its rearjend swings in the di-' rection of the arrow thereon, Fig.1? far enou'gh of the end 24 and the slotted end of the trans ferrer, while the feed-lever, by its part b acts" against the proj ection'C, and causes the swing frame B -to be moved or vibrated for the necj essary distance. If a fastener should fail to] arrive in proper position in front of the transferrer, as the lattenismov'ed forward, the finger 6 would not be acted upon and moved, be-

cause it can be moved only by the head of a fastener, and consequently the detector would not be moved so that its end 24 will be caught in the slot of the transferrer, and hence the detector will not be turned to operate the feed regulating lever, and the feed-lever, as it is moved forward, will-not strike the projection II IO 0, and the swinging frame'will'not be moved, 1 and the feedof the material will not take place, nor will the buttonwhichiwas to be fastened r by the tack which failed to'come into position be withdrawn or thrown out of the button chute. receives in its groove a stud orroll of a lever, G", mounted on a movable fulcrum-pin, G held in cars of a short lever, G, pivoted to the frame 13* at.

Provision has been herein made to accommodate the stroke of the driver to the thick ness of the material, and this is accomplished through mounting the lever G on a movable fulcrum; and on inspection of Fig. 4 it will be understood, when the end of the driver-bar or a shoulder thereon meets the lower end of the centering device or throat N, that the further movement of the driver-bar will be arrested, provided the upper end of the. centering device or throat rests against the material, and during the further movement of the rear end of the lever G by the cam G the fulcrum G" descends without lifting the driver, and consequently we are enabled to impart to the driver a variable throw, so that the extent of the curve in the body of the fastener is more or The driver will be permitted to end its drivingstroke short of the end of the centering device or throat, such distance being usually a little fastener, in order that the said head, under all thicknesses of material, will occupy the same ton-agitator H, (shown as a disk or hub hav-- ing brushcsor arms 28.) Thehub of the agitator is mounted at the upper end of a shaft, H extended upward through a hub, 1-1", below the bottom plate. H, of the hopper or receivcr. The shaft H has a gear, M, which is driven from agea r, M, fast on shaft B", through an intermediate, M". The bottom plate, 11, is herein shown as constituting a part of the under-plate, 27, of the button chute or conductor E. This plate 27 has a rounded groove or channel, 30, extended from the receiver to the delivery end of the said chute, and communicates at its upper end with the said receiverH, so that buttons mayenter the said groove and roll or slide along the same to the delivery end of the chute. Inside the receiver,

and next to one of itscircular walls, there is placed a grooved bridge or race, 9, upon which the buttons are raised by the arms of the.agitator, so that their heads, resting next the inner wall of the receivery'ns shown .in dotted lines, Fig. 13, roll along in the said race, the

. shanks of the buttons projecting toward the center of the said receiver. The agitator sweeps the buttons-along the race 9, and from the end of the latter, which is extended through the outlet'29 of the receiver intoa pocket at the said outlet, as best shown in Fig. 1- the heads of the buttons then entering the groove 30 of the under plate, 27, along down which groovethe said buttons roll until they arrive at a point near the delivering end of the said button-chute.

In Fig. 11 it will be seen that the under plate, 27, is'the ividest along the straightcst part of the chute, and by such construction the button-shank is kept horizontal, and the button is free to roll, because it stands on its edge; but as the button reaches the lower curved end of the chute the top plate of the chute is made the widest, (see section, Fig. 11%) and the groove in it is a little wider or larger than the groove in the under plate, 27, and consequently the button is permitted to tip over so that its shank points downward at an angle of about forty-five degrees and bears upon a knife-edge at 32, at which point the under plate, 27, forms a rest or support for the button which is being attached to the shoe or other article. The cndmost button of the series of buttons, with the open part of the eye uppermost, will be arrested by a yielding stop, 33,"

(see Figs. 10 and 17,) and exactly at its proper position with relation to the driver and anvil, so as to insure the entrance of the prong 9 into the eye of the button as the carrier D is turned in the direction of the arrow on it, Fig. 4.

The centering device or throat N, attached to ihc upper end of the bar N" by a screw, 34, is composed of a head provided with two spring-held jaws, 35 36, pivoted at 37, (see Fig. 22,) the spring 38, acting thereou,'being held by a screw, 39, inserted in said head. The bar l is acted upon by the spring N", one end of which is connected with a bolt, N, attached to the frame .13, and its other end with a pin, N, extended l'ron1 thc said bar through a slot, N, (see Fig. 4,) in the swinging frame 13', and consequently the upper end of the centeringdcvice or throat is self-adaptifig to the thickness of the stock; but the said bar N is drawn down by the lever O, pivoted to the frame .13 at 0, the said lever having a stud or roll to be acted upon by the onesided cam 0, fast on the shaft ll".

The driver-bar c is held in its groove by the dovetailed gibrp, itin turn being held inplace by screws 12'.

The under side of the under plate, 27, of

the chute E serves as a support for the'matew 'rial upon which the button is to be set as the centering device or throat strikes the said material. The material is held up against the said support by' the presscr-foot P. (Herein shown as inverted from the position commonly occupied by presser-fcet in sewing-machines.) This presser-foot I has a throat, I, which is entered by the centering device or throat of the fastener, and is attached to a presser-bar, P, extended through guides 1", forming part of the rigid frame A, the said bar passing through a spiral spring, P", which has its lower end rested on a projection, 1, of the frame 1 and toperinit it to be otediat 36,,forked at o v H or. block, P of the said ba t, and having at its other end a roll or stud to be acted upon by To depress the 'presser for the introduction or l earr n receiving against it a collar, P fad u'stablyattaeh ed to the {said-bar, the saidsprin'g acting normally to ele-j maneantennae. ande u t o mp;

removal'pf the materiatthe p'resser-rod is extendedjbelow the frame-work A, as in Fig.2,

and has joined to "it a link, r, supposed to be attached to atrcadle'or fo0t-piece. The swinging frame is normally held against the back into the eye of the shank, and place the clinching-surface 8 opposite the said eye, and at the sametime the transfcrrerF is moved for- -'ward to carry the fastener into position above the end of the driver G. When the head of the fastener is thus placed above or in line with the driver,thepoint oi'th'e said fastener is just below the contiguous ends of the springheld centering device or throat, and the upward movement of the driver causes the point of the fastener to be moved up between the contiguous ends of the jaws of the said centering device} thelatter then being at rest-ashort distance from the under or wrong side of the material, after which the centering device and driver move in unison tojvard the material,

and the centeringdevicc, striking the material through the throat P,is stopped thereby; but thedriver continues to operate against the head of the fastener, and drives its point through the material and against the clinching-surface 8 of the anvil, causing the point of the fastener tobe curved or curled or clinched overseas 'to inclos'e thewire of the shank of the button, the driver stopping automatically initsdriving' movement, preferably just be- .foreits end arrives opposite the end of the centering dc'vice,'as described. As the fast- ,ener is being clinched to secure the button in place, the presser-foot is automatically lowered by thccam O to release the material sufficientlyto permit the same to be fed, which is.

and just before the centering device and anvil release the material,to enable the frame B to beswung back intoits normalposition by the spring b, the presser-foot is elevated by the spring P, to clamp the material so that itcannot be displaced until the next button has been set. If the fastener fails to be delivered .properlyto the driver, the feed-lever in its movement fails to strike the projection G, and the material is not fed, and the button re mains in the button-chute with the prong 9 in the eye of the shank,and is not fed. In order to keep a record of the number of buttons-set by the machine, the latter will be provided I (Shown inFi-gs. 1 and 22.) This counter is shown as a box, 7, within which, as usual, are several gears and pinions, making a train to drive a pointer, 90, over a scale, the mainn-atchet 96 of the train being engaged by, a pawl, 95, attached to the hub of the swinging frame B, the said pawl acting to turn the said ratchet one step at each return movement-of the frame. The box of the counter is attached to the fixed frame A. r
