BUTTON-SETTING MACHINE.

Original application filed May 10, 1915, Serial No. 27,042. Divided and this 1915. Serial No. 61,326; v

To all whom it may concern:

Be it known that we, FREDERICK E. STAN- LEY and GEORGE R. LEGGETT, citizens of the Ilnited States, residing atWaterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Button-Setting Machines, of which the following is a full,

clear,'and exact description.

Th1s invention relates to a power machine for setting tack fastened buttons on garments and other. articlesrapidly and accurately, and more particularly to mechanism forming a part of such a machine for presenting the buttons in proper position and relation to the tacks for setting the buttons on anarticle.

This case is divided out of our 'appl1ca tion for-patent for button setting machines,

filed May 10, 1915, Serial No. 27,042, in accordance with the requirementof the Patent In all prior button setting machines-of this type known to us, the buttons are presented to the setting mechanism by means of an inclined raceway down which they slide bottom-side up and in which theyv are,

righted by means ofa reverse, bend in the v raceway. But this method has many disadvantages, among which are the following,

viz.. that the-buttonssometimes jam in the raceway when they come to the reverse' curve; and that gravity being depended uponto right the buttons, the feed isnot al-v ways rapid enough tomeetrthe requirements of the machine; so that at times a tack. is

presented with no button to which to apply it.

The object of this invention is to provide mechanlcal means for righting. the buttons which does not depend upon gravity except for the initial presentation of the buttons to it from a chute or raceway in which the but: tons run bottom-side up and in a straight line, whereby the above mentioned disad vantages of previous constructions are done away with and an increase in speed in the setting operation of the machine and the number of buttons thatmay be set per minute by the machine, is obtained.

The invention consists in whatwe will herein call a button turner? adapted to re Specification of Letters Patent.

Patented May 16, 1916. application filed November 13} and to turn them into proper position for appllcati'on of the tack to 'aflix the buttons .cei've the buttons edge up and one at a 'tii ne I from a racewayconnected with a hopper,

to the article to which they are to be applied,

and inmeans for driving. the parts, as we will proceed nowto explain and finally claim. I

Fig. 8 is an inside elevation of the buttonholder, and Fig. 9 is a side elevation of one of the two fingers of .the button holden, Fig. ;10-'i's'a sectional elevation of the tack holder and plunger. 11 is a vertical" section taken-.inthe plane of line AB, Fig. 3, looking toward the right, but.

showing the parts in position when the button has been set. Fig. 12 is an edge view or for the purpose, among others, of running the machine at high speed. The shaft 4 is provided with any suitable means preferably a band-pulley 7, for application of power by "means of a roundbelti8. ,The

shafts 3 and 4 are mounted in hearings in a head 9 erectedfon the bed-plate or table 1,

" and-the gear is arranged loosely upon its shaft 3 with any suitable friction'or other 1 "clutch (not shown) interposed between the Y shaft and gear and operated by any suitable means to cause the gear to turn with the "shaft, as by a lever pivoted on stud-shaft 11 mounted in boss 12 on the head, andcon- -nected with a treadle 13 by a rod 14, but

other suitable means may be used for startingand' stopping the machine instantly.

The driven parts of the machine derive motion from the main-shaft, as will appear more fully in the progress of this'description, and we have found that the high speed required and the necessary control of the machine'are best obtained by applying the power by what is commonly called a round belt not directly to the main-shaft 3 but to a driving shaft 4, and gearing these shafts by a two to one or other desired train of v gears 5, 6, the main shaft having the stop-- ping andstarting mechanism applied to it.

The button magazine or hopper 15 and the tack magazine or hopper 16 are mounted upon thehead in any suitable manner, and

j at any suitable angle, and so as to becapableof being turned to effect the discharge of their contents. Preferably these magazines have their shafts 17 and 18 respectively extended rearwardly and supplied with bandpulleys 19 and 20 respectively, which are fast on their shafts and are connected by the band 21, so as to turn in the same direction. The shaft 17 is driven by a pulley 22 connected by a band 23 passing .over direction idlers 24*and 25 to a driving pulley 26 on the main-shaft. The pulley 22 is loose on shaftl'? and carries a pawl 27- which engages a ratchet 28 fast onshaft 1'1. -The buttondriving pulley 22, soas to remove obstacles and provide for emergency filling, and the filling of the raceways leading from the magazines to the setting devices, whenever they become empty 'or insufficiently filled. The tack hopper may be secured to its shaft 7 in any suitable way to turn with it as de-' sired, and we haveshown a nut 32 as the means for retaining it upon its shaft.

The buttons are discharged from the magazine into a raceway 33 depending therefrom, with their hubs outermost, and must be turned for setting purposes, so as to present their hubs lowermost and vertically.

The lower end of thejraceway, is intercepted transversely by a reciprocating cut-01f 34,

actuated by a rock-lever 35 pivoted on the head of themachine, a connecting link 36', a spring 37 and a cam 38 on the main shaft,

to deliver one button at a time, and below this cut-off is an offset raceway 39 which opens into a transversely arranged casing 40, in which is arrangedthe button-turner that receives the button edgewise from the raceway and gives'it a quarter turn so as to present its hub vertically downward. This turner comprises a cylindrical piece 41, having a diametrical opening or slot 42 at one end,.of a size suflicient to receive the button edgewise, and it is provided with circumferential spur-teeth 43 outside of the.

casing which are engaged by a toothed rack 44 on a longitudinally reciprocating bar 45 mounted in the head of the machine at the rear of the turner and actuated by a cam" turner is turned with its opening vertical to recive a button edgewise from the race-way and then it is turned a quarter turn so as to move the button from a vertical to a horizontal position with its hub down and in the position it must have in order to be set. The turner piece 41 is bored longitudinally and in this bore is mounted a stem 49 having the transverse head 50 curved on its face to conform to the curvature of the rim of the button-head. The stem projects out of the toothed end of the turner device and its head works in the opening or slot 42. r The stem is provided with an adjustable grooved collar 51 which is engaged by a tracker pin on a shifter lever 52 pivoted on the head of the machine and having a cam roller engaged by a cam 53' on the mainshaft, so that-When the machine is running the stem and its head will be given alongitudinal reciprocating movement in the turning device to eject the turned or righted button therefrom, and because of this function the stem and its head are herein referred to as an ejector. The cams 38 and 53 may be and are here shown as one structure. In order to obtain access to the turner to remove a defective button and for other purposes, the bottom of the casing is made with a hinged gate 54 provided with a pivoted spring or other effective latch 55 engaging a slotted keeper projection 56 on the casing,-see Figs. 4, 5 and 7, for details. 7

. By means of the button-turner or buttonrighting device described, the positioning of the button is removed from the uncertain automatic action of the priorart raceways, to a certain and positively acting mechanism, with the result, among others, that the speed or capacity of the machine is greatly increased, and its operation attended by relatively few misplaced or improperly set buttons.

The buttons are delivered, one at a time, to the spring closed fingers 57 ,mounted upon the side of the head and having their lower ends '58 turned toward the turner last described. These fingers are hinged togethertical anvilpassage, to form a pocket 61,- of

substantially the profile of the button, into which the buttons are successively ejected by the ejector, and by means of this pocket the button is held in the fingers against the possibility as well of misplacement as of accidental displacement.- The fingers are held in longitudinally sliding engagement with the head by a screw 62, the head of which is large enough to overlapthe fingers at their greatest lateral separation in operation. The

upper portions of the fingers are cut away to form an intermediate slot 63 and into this slot projects a pin 64 fast on the anvil. Above the pin is an adjustable spring adjusting device 65 on the fingers, to adjust the finger-ends to the turner and take up any shock. The anvil 59 in its descent comes into contact with the finger-ends and carries said fingers down'with it until said fingers reach the limit of their downward .movement, which is determined by the relation of the screw 62 to the slot 66 between the fingers in which it is arranged. The fingerends are moved by the anvil into a position lower than that of the "turner, and then the further descent'of the anvil and itsconsequent ejection of the button cams the fingers apart under resistance oftheir spring,

.the head so as to operate within the slot 66 to separate the fingers whenever desired. When in thisposition the turner opening or slot 42 is in horizontal alinement with the pocket 61 in the finger-ends and the ejector is in position to eject the button'from the turner into the pocket in the fingers.

Theanvil may be operated by any suitable means, such as abell-crank lever 68 mounted in the head and connected with the anvil by a link 69,: the lever 68 being actuated by a connecting rod 7 0 extending thence rearwardly and forked to straddle the main shaft and having a cam-roller 71 engaged by a cam 72 fast on said main shaft which imparts a compound longitudinal and rising and falling motion tothe-connecting rod and a rocking motion to the bell-crank lever 68.

The'tack magazine has a raceway 3 made with atwist so as to receive the tack heads on edge from the magazine and 'turn' the tacks point up before they reachthe cut-off 74. This cut-off has two fingers 7 5 having their tips 76 extending toward one another across the raceway, and these fingers are fast on a rock-leverv77 pivoted on the back. of the racewayand connected by. a rod 7 8 with a vibrating arm '7 9 pivoted at 80 to the head and having a cam-roller 81 engaging a cam 82 fast on the main shaft. In order tofpre vent breaking of parts in the event of jam-'- ming the raceway or cut-oif,the rod 78 has a. coil 83 formed in it to serveas a spring which will yield under such jamming and thus prevent breaking any of the parts. The rock-lever 77 and its fingers 75 may be returned to position by a spring 84: fastened to said lever by one end and to the head by the other. The tacks are delivered one by one to a feed trough 85 arranged in the -head beneath and in line with the anvil, and in this feed trough is a tack ejector 86 of. the kind shown in the parent case referred to. This tack ejector is reciprocated in the feedtrough by means of a bell-crank lever 87 pivoted on the machine head and having one arm connected by a link 88 with an upstanding lug 89 on the ejector, and another arm provided with a cam-roller 90 engaging a cam 91 fast on the main shaft. The tack ejector delivers the tack to fingers 92 pivoted to the head adjacent to the setting die or plunger 93, these fingers being yieldingly connected, as by a bow spring 94. A stop 95 prevents the escape of the tack and also serves to position it on the plunger;

The plunger 93 is vertically reciprocated in the head and between the yielding fingers 92 by a bell-crank lever 96 pivotally mount ed in an extension of thehead beneath the bed-plate l, and connectedwith the plunger by link 97 and having a connecting rod 98 provided with a forked end which straddles the main shaft and is provided with a cam roller 99 engaged by a cam 100 fast on the mainshaft.

We have herein referred to. the cams 82,

'91 and-100 as though each were a separate structure, as they may be, but they,' are herein shown as combined in one structure. These and other details of construction and operative parts are variable at the leasure of the machine builder, so long ast e eflec tive cooperation and coordination of parts are concerned and the principle of the invention'followed. Again, it is to be. noted that we have. described the button turner'inbroad terms, in order to emphasize the'fact that we do not wish to be considered as limiting our invention to details. In the drawings, however, one construction only is shown, and this illustrates the cylindrical piece 41 as having a reduced portion 101 next to the teeth43 and fitted in a sleeve 102 having a rear extension 103 fixed to the back of the casing, as by screws 1. This cylindrical piece is held in the casing and sleeve by the collar 105 fixed to the reduced portion 101 outside vthesleeve. The casing in this instance is a part of or attached to the lower end of the button raceway. The teeth 43 may be cut in the piece 41 as shown, or other ,wise provided.

The operation would appear to be suiticiently indicated in and by the foregoing. However, it may be briefly stated that the respective magazines being supplied with ,buttons and tacks and the machine started, 'the buttons and tacks are fed one by one to their respective delivery points. The article to be supplied with buttons, represented at momentarily beneath the anvil.

106, Fig. 14, is passedby the operator bethe tack and the .plunger is caused to ascend and pass the tack point through the article and into the combined anvil and filler 109 in the button wherein it is clenched and the button so set. Then the parts reverse, the article is moved along to a point where another button is to be attached, and the operations repeated. The spring fingers 92 yield in the direction of movement of the article and thus offer no obstacle to the release of the set tack, but rather facilitate it.

As already 'sufliciently indicated, the invention contemplates such changes as will meet the requirements of the user, the kind or type of button to be set, and the kind or type of tack or fastener.

The claims for the combination of the button supplying means, the tack supplying means, and the mechanism for bringing the, buttons and tacks into setting relation and for setting the buttons, form the subject of the parent application hereinabove mentioned, and the claims for the mechanism 4ft; acting upon the tacks form the subject ofiour concurrent divisional application of Leven flate, Serial No. 61,327.
