Specification of Letters Patent.

Application filed January 3, 1913 Serial No. 739,930.

To all Ir/mm it may concern Be it known that I, FRANKLIN R. WHITE,

a citizen of the United States, and a resident of VVatei'town,

in the county of Litchfield and State of Connecticut, have made and invented certain new and useful Improvements in Button and Staple Feeding Mechanisin for Button-Attaching Machines, of

ferred embodimentof though it will be understood that my invenwhich the following is a specification.

My invention relates to button and staple feeding mechanism for button attaching machines of the type wherein buttons are atfastener by an upsetting; riveting or similar operation, and the object thereof is to, provide certain improvements in and relating taclied to a garment by means of a suitable to various of the elements which collectivelyform the button and staple feeding mechanism of abutton attaching machine-of the type above referred to, all as hereinafter separately referred to and described and finally claimed.

Referring to the drawings wherein the preferred embodiment of my invention is illustrated, the reference numeral '20 designates a suitable support or pedestal, and 21 elevation which may be designates a suitable frame secured to the upper end of the pedestal and supported thereby, and which frame serves to support/ thevarious operating elements of my improved button attach g machine ii pro er position relative to one another. The pe' estal carries a table or tray 22 at its upper end and is provided with a bracket 23 having bearings wherein a shaft 24.- islsupported and i from which the operating elements of my. through a connecting" machine are driven rod 25 the lower end of which is connecte with a crank arm 26 carried by the shaft 24.. Th-e'shaft .24 is operated from a. loose pulley 27 upon the shaft, suitableclutch mechanism not shown being provided w ereby the pulley may be operatively connected ipo , wwith tlie shaftto drive the machine, which clutch niechanismis operated from a treadle through the rod 28.

Pivotally support-s d ba the frame 21 ofthe. machine is arr-oscillating lever 29, one end of which isoperatively connected. with the connecting rod 25 at 30, while the other end of said lever is operatively connected with a vertically movable button setting plunger 31 through a link 32, said plunger being guided in its movements by a bearing provided for it-in the frame-21, as best shown in Fig. 13L The lever in question thus oscillates about an axis at 33, Fig. 1, as the operating shaft 24 is rotated, as will be understood; and the end of said lever is bifurcated to receive the upper end of the link 32 and is cut, away to provide circular engagement therewith; and 3? is a rem'ov-' able die or heading pin, the upper end of lower end of the which is. dove-tailedand fits within a transvcr dovetailed roove 38 formed in the giunger as shown in Figs. 13 and 15, and the lower end of whichextends through an opening'89 in the lower end of the sleeve 36, whereby the said die is held in a properly centered position with reference to the plunger 31. The lower end of the die is provided with two transverse grooves. 40, Figs. 18 and 19, separated by a central ridge 4]., with. which grooves the points ofa double prouged button attaching staple of the form best shown in Fig. 6 engage when theplunger is moved downward, and whereby the pointsoi the prongs .are pieperly guided past one another and revented fromengagmg, as the prongs are p ent orscurved 1n the manner illustrated in Fig.15.

he construction above disclosed obvious ly permits the button setting plunger to be readily remdved" from the machine and 1 a new die or heading pin substituted for one worn in use with a minimum amount of dismantling of the machine.

The reference numeral 42 designates an anvil located in line with the plunger 31 and supported from the frame 21 asthrough aprojecting flange 43 in contact with the irame, which anvil is held in place by a nut :44 inengagement with a threaded extension of the anvil, asshown in Figs. 13 and 14, and upon the upper end of which anvil the two-prong'" staples whereby the buttons j are secured to a garment rest preparatory to i and. while the button is being secured in place; 1

f Surrounding the anvil 42 and guided in it movements thereby is a vertically yicld-' able jaw carryingmember 4.5, the same bcing held inits normal uppermost position by. a spring 46 and the upward movement thereof being shown as limited bya portion of said member coming into contact with the under side of a staple receiving table 47, to be more fully described hereinafter. The said jaw carrying member is provided with two pairs of pivotally supported jaws, the rear pair 48 serving to guide the fas tening staples as they are moved from the table 47 onto the anvil 42, as will be hereinafter explained, and to prevent the staples from taking a positionwith their prpngs lying in a plane .at an angle to the direction of movement of the staples; while the front jaws 49 grasp'the staples after .they have been moved onto the anvil and hold the same in an upright position while ,a.button is being attached to a garment; all as illustrated in Figs. 3 to 6, and 13 of the drawings. Both pairs of jaws are preferably provided with inclined surfaces 50 adjacent their upper ends, and the upper end. of the anvil is shown as provided with similar inclined surfaces 51; the purpose of these features being to avoid possible injury to the jaws and anvil as the jaw carrying member 45 and the jaws carried by the same move slightly downward in the normal operation of the machine as will be hereinafter explained, and to permit the overhanging upper ends of the jaws to lie close to the upper end of the anvil without rendering the jaws and jaw'carrying member liable to injury when the machine is in use. The operation of the machine, however, is not dependent upon. contact of the inclined surfaces upon the anvil and. jaws coming into contact with one another; and the feature of supporting the jaws upon a vertically yieldable member is provided in order to avoid normuloperation of the machine. The jaws.

aforesaid are pivotally supported at their lower ends by pins 52, which pins are held in place by akeeper or latch' 53 carried by and rotatable upon a pivot screw 54 and which keeper may engage or be moved off from the lit heads of the pins to thereby permit the pivoted jaws to be easily removed after the removal of the pins. The pivoted jaws are forcedtoward one another by means'of loop springs 56, 57, the free ends of which rest in recesses formed adjacent the upper ends of the jaws and the loop portions Of;.WhlC l1 springs lie normally beneath the keeper 53,

as shown in Fig. 2, and are prevented from ator y said keeper; When, however, the longer or right hand end of the keeper is swung upwardpreparatory to removing the rising3 and getting in 'the way of the opcr- A V l 2,, pins and jaws, the springs may be swung upward and easily grasped by the fingers in order to remove them.

From the above it will be obvious that the rear jaws may close independently of the forward jaws; and the said rear jaws will,

when the machine is in operation, close to" form a guide for the succeeding sta le at a time when the forward jaws may e still held apart by the head of the staple, the material of the garment, and the downwardly extending hub of the button, as will be understood from Fig. 14, the rear jaws being made somewhat shorter than the frontjaws in order that the garment may not ingarment, whichis a feature of importance especially in machines designed to operate at high speed.

The reference numeral 58 designates a support or bracket resting upon an'dsuitably secured to the lower portion of the frame 21 and which block serves as a support for various elements of the staple or equivalent fastener feeding mechanism of my machine .The said bracket is provided with an onening adapted to fit over the collar 43 of the anvil and whereby the anvil and the ele ments of the fastener feeding mechanism carried by saidjbracket are kept in proper position relative to one another. The under side of the bracket being flat, and the surface of the frame upon which it rests being also flat, the bracket may be easily adjusted about the anvil as a center and made to cocupy a proper position relative to the'lower end of a supply chute 59 to be hereinafter more specifically described, so that the fasteningst-aples will be properly fed to the staple holding jaws and tc.-..the anvil. The bracket 58 supports the Fastener receiving table 47 above referred to, which table is provided with a slot 60; and the said bracket is provided with a guide-way 61.. located beneath the slot 60 and within which guideway a reciprocating staple feeding slide 62 operates, said member having an armJGit extending upwardly through the slot 60 and along the upper surface of the staple receiving table 47. The free end (34 of the arm 63 is adapted to engage successive fastening staples after they pass from the lower end of the staple chute 59 onto the table 47,, and to push them from the table onto the upper end of the anvil and between the upmages a per ends of the staple grasping jaws 49 hereinbefore referred to, as will be under stood from Figs. 3 to (3 of the drawings.

The fact that the staple feeding chute 59 is arranged to discharge downward and at i an pbtuse angle .to the path along which the "fastening staples move toward the anvil, as will be understood from Figs. 7 and 8, insures that the fastening staples will slide onto the staple receiving table 47 in the same direction as the direction in which they are to be subsequently moved, and with a minimum of retardation and liability to displacement; and that they will be less liable .to assume a position which might result in jamming of the staple feeding mechanism as they are advanced toward the anvil and holding jaws than would 'bcthe case if'thc staple chute extended at right angles to the staple receiving table.

The staple feeding slide is provided with a downwardlyextending pin (35, and 66 is an oscillating bell-crank lever pivotally securcd to the bracket 58 at 67 and one end of which is bifurcated to engage the pin ('35. The lever (56 is operated from the oscillating lever 29 by means of a pin 68 operating inanelongated slot 69 formed in an oscillating lever 70 pivotally secured to the frame f 2]. at 71, which lever has an arm 72 operatively connected with a cross head 73 slidable upon a pitman 74 the other end of which is operatively connected with the hellcrank lever 66 above referred to. -A spring 75 surrounds the pit-man 74 through which spring motion is transmitted to the slide 62, and which spring will permit the .(l'OS-S",

head to move without moving the lover (it in case a staple gets jammed or-caught on its way to the anvil and staple'holding jaws; thus avoiding injury to the reciprocating staple feeding slide as will be understood.

The bell crank lever 66 is provided with a screw 76 adapted to engage the bracket 58 when the lever is at the end of its moveinent in the direction which results in movement of the staple feeding slide 62 toward the anvil, to thereby limit the movement of the slide in that direction, as will be understood.

The slotted oscillating lever 70 is pro: vided with a second arm 77 in operative engagcmcnt with aipivotally supported lever 78, which lever operates an oscillating staple escapement 79 through a suitable connection 80, and operates also a rotary staple hopper 81 through a suitable connection 82 and. suitable ratchet mechanism located beneath the hopper and designated as a whole by the reference character .83. This operating mechanism is not illustrated 'in detail, as

the same forms no part of the invention to which this application relates.

The staple esca 'iement 79 is nvotally sejcured to the under side of the staple chute staple hopper-from becomin 1 as the arm moves into the position shown in 'Fig. 8. The second arm 86 of the es capement is provided with a'stop 88 adapted to arrest the downward movement of the staples when in the position shown in Fig.

'8, and with a staple accelerating projection 39 having an inclined edge 90, which edge, as the arm by which said accelerating projection is carried is'moved into the position.

; shown in Fig. 8, engages the lowermost 2o staple and gives it a positive push, thus starting the staple toward the staple receiving table with a more rapid motion than would be the case if the force of gravity, alonefwas relied upon to move the staple as it is released by the stop 87.

The rotary staple hopper 81, see Figs. 11

and 12, is substantially cylindrical in form,

and its lower end is'provided with a series of slots 91 adjacent its lower end designed to. pick up separate staples from a mass of staples within the'hopper, and to discharge them into a space 92 from which they pass into the staple chute 59, all, in accordance with the usual operation of feeding mechanism of the type illustrated. The said hoppeer is supported upon a base 93, which in turn is supported from the frame 21 by means of a bracket 96, and rotates about a central axle, and, in order to prevent the jammed after the staple chute is fullo staples as by reason of staples within the slots 91 failing to fall thercfrom, I provide an opening or recess 94k in the base over) which the slots 91pass and into which such staples as do not pass into the chute may fall. This open ing or recess is cut ,off from direct co1nnuinication with the interior of the hopper by reason of the fact that it extends only 5 beneath the slots 91, and not'inwardly beyond the slots, fromv which it follows that the mass of staples within the hopper canrnot interfere with or prevent the staples from falling from the slots. The said recase is preferably located adjacent the end of the'spaee 92, so that staples carried to the end of the space may not be. caught between the hopper and thebase'93, but will fall into the recess, and the recess preferably comnnuncat-eswith the inter or oithe staple vhop-per as through a passage 95 that the staples which an amnesia return automatically to the interior fofth taplehoppcr.

It. will of coursebel'fiinderstood that in- -;s feeding'hoppers tithe type employed in my,

machine, it is expected that the articles fed which do not pass out of the slots and into the chute, will fall from the slots into the interior of the hopper as the slots move into their highest position, thus avoiding jamming of the hopper. This operation will commonly take place if the hopper is only partially filled. Operators are, however, prone to fill the hopper as full as possible with buttons, staples, or-whatevcr articles are being fed. or at least too full, in which case-the articles may be prevented by the mass within the hopper from falling from the slots into the interior thereof, with a resultant tendency to jamming by the articles bein carried to the endof the space into whidli the articles normally pass on their way to the chute and there caught between the hopper and the base upon which it is supported.

The feature above referred to of providing for a more positive discharge of such articles as fail to pass into the chute may obviously be used with feeding hoppers designed to feed any articles, whatever, and is used by me in my machine upon. both' the staple feeding hopper and the button feeding hopper, although the feature in question is illust ated in detail onlyin connection with and as applied to thestaplc feeding hopper.

The fastening staples after having been released by the cscapement 79 as hereinbefore explained, pass from the lower end of the staple chute onto the staple receiving table l7 and rest thereuplm in an upright p-ositimi between a guard 5)? formed by one side of the lower end of the staple chute, see Fig. (3 and Fig. 8, and a second guard 98, Figs. 3, t and S pivotally secured to the bracket 58 at 99, so that said second guard may be swung away from the lower end of the chute in order to permit the removal of a staple should. one become a nghtor jammed in thisportion of the machine; the two guards thus tor-mi. a groove or raceway along which the staples pass on their way to the anvil. The pivotally supported guard is held in proper position by means of a pin 100 extending therethrough and into a hole in the table 47.

The reference numeral 101, Fig. 1, designates a guard pivotally secured to the lower.

end of the staple chute 59 and extending over the points of the staples to thereby prevent the garn'lent to which the buttons are attached from coming into contact with the said points.

The reference numeral 102 designates a rotary button feeding. hopper designed to receive a mass of buttons and to supply the same to a downwardly extending button chute 103, wliiehchute is twisted as shown in the drawingsfin order thatthe buttons min ay he supphedto' a. but

ton receiver form tau button receiving vmembers 111 to "herotyy 1 l l l mg a part of my machine, right slide up, 1n which position they are securedt'to a garment designated by the numeral 1.04. This button hopper is stippdrtedupoh' a suitable base 105, which in tiyrn is mipported from the frame 21 by means of a 1 hitable bracket. Thebutton hopper rotates hbout a suitable axle; carried by the b se, arfl rotary motion is transmitted tothe same f-bm the oscillating lever 29 through a pitirth n 1O? and suitable; ratchet mechanism designated as a whole, by the numeral 108, the said "iatchet mechanism and the hoppen itself, htwever, not eing illustrated in detail asth same forni no ,part of the invention td wh bh this applicati n relates. i l

The numeral 109, designates an tfscillat-i ing button escapement pivotally colhnectetl with the button chute and designed to re lease buttons ibne .by one and permit them to pass down the button chute to a button receiver to be fnext described, which escapement is operated by means of a projection upon the levei 29 which engages therewith, which features, however,'fo1'm no part of the invention to which this application relates.

The buttons, after having been released by the button escapement, pass from the lower end ofthe chute into a cup-shaped cavity formed by oppositely located'recesses'llO at the outer or free ends of two adjacent cooperating button receiving members 111 suitably supported by a supporting member 112 shown as in the form of an oscillat ing arm, the rear end of which is pivotally supported from the frame of themachine at 113, the free ends of said members being separable so. that a button resting within the cavity formed by the recesses 110 may be for ed downward by the plunger 31 and through the bottom of the cavity as the ends of the arms move apart ftom one another, the said members thus forming a button reeeivcr designed to receive a button fyom the lower end of the chute and to hold. t le same preparatory to its being secured to a garmeat. The said button receiving niembers are shown as providedweaeh ,with a curved recess which bears upona tttitl 114 lillvinga flange 115 at its upperlend, as shown -in Fig. It and a sprin'g'lltl ie-provided forhoidin g the member's together and ipositions, which s ')r1ng, howeve perntits the tree endis of the membersto inovd apart aboutthei stud as a center. The arm 112 carries alsoia double lobed cam 1117 see ired tin place by a screw 1 18 and theilobes 0' which eam may be made lto act, as by rotat; ng the same upon the screw 11 by meas of a handle 119, upon a surfaebf eachll of the force the free outer eiuls of the membes apart and thus permit a bu'tton wit- 1n the cavity aforesaid, and which 1s not t be scity formed by the recesses 110 is of a conformation to permit the buttons to pass into it with a minimum of friction and consequent retardation and to at the same time reduce to a minimum oscillating or rocking motion of the button after it has passed into the cavity, to which end the rear portions 122- ofthe recesses are conical surfaces, while the front portions 123 are plane surfaces extending longitudinally of the button receiver and inclined toward one another,

-so that the lower portions of said. plane surfaces are closer together than the upper portions. rom this construction it follows that the advancing edge; of a button as it passes into the cavity will engage the-inclined surfaces 123 at two points only, and because of the slight amount of friction between the button and these surfaces, the but-' ton will slide into the cavity with but slight retardation of its motion, during which movement its front portion of the button will be raised. and the button swung into a horizontal position, as will be understood. When the advancing edge of the button reaches the forward vertical. wall 121' of the cavity, the button will have'been brought into a substantially level or horizontal position and the rear or following edge thereof will fall into the cavity and will contact with the conical portions 122 thereof throughout or along nearly one-half of its entire extent, the advancing edge of the button would contact therewith along a considerable portlon of the edge, and the resulting friction would tend to prevent the button from coming into a horizontal or levelposition, thus interfering with the operati n of the' machine.

The button receiver above referred to and described will obviously move up and down in the operation of the machine, for which anvil 42 between the staple holding jaws the free ends of the button receiving mem- 7 fastening staple have been drivenvthrough reason I refer to it 'asa vertically movable 'vention includes a button receiver having 'ofthe hub of the button is forced-between buttonreceive'r 5' and, while I have shown the, said; receiver as carried by an arm which-is pivotally connected with the frame of the machine, it will be understoodthat mydn an up and down movement, together withtheother elements and features enumerated in the claims in combination therewith, ir. respective of the particular. mechanism employed for permitting such-i'vertical or up anddown movement.

The arm 1 2 is provided with a lifting member 125 upon its under-side and which member-is shown asdoosely supported in a slot formed in the endof said arm as by means of a transversely extending pin 126. The forward or free end of this arm lies closeto the hub of the button after it has been attached to the garment, and thepur" pose of said member is to pull or to assist in pulling the attaching staple and the hub of the button from between the staple graspingjaws 49, after a button has been secured inplace, to thereby insure that the said jaws willclosc as early as possibleinthe cycle of operation of the/machine and thus permit the succeeding attaching staple to .be advanced onto the anvil earlier than would be the caseifthe closing of said jaws was delayed; Y 4

In using my improved button'attaching machine to attach buttons to a garment, the edge of the garment is placed beneath the button receiver and overthe anvil and jaws hereinbefofe referred to asshownin Fig. 13. Thereupon, (it being assumed that a staple has ,been placed in position upon the 49, and a button supplied to the. button receiver, both as hereinbeforc explained) the plungcrBl is moved downward until its lower end enters the button receiving cavity (bftlle button receiver and engages the but; ton,.after which the button receiver moves downward with the plunger." The downward'movcment of the button receiver is finallyarrested as the edge of the, garment is caught between its 'lower surface and the upper surfaces of the-staple holding jawsc 49, after which thebutton is forced along the inclined wall of the button receiving cavity and through the bottom thereof as here 111 move apart from one another. In the meantime, however,'thepoints of the the material of the garment' and through the base of the button, and, as the plunger continues to move downward, the lower. end
