Original application filed May 10,1915, Serial No. 27,042; Divided and this application filed November 13,

To ail whom it may concern:

Be it known that we, FREDERICK E. STAN- Lnr and GEORGE R. LEGGETT, citizens of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Tack-Feeding Mechanism for Button-Setting Machines, of which the following is a full, clear, and exact description.

This invention relates to a power machine for setting tack-fastened buttons on garments and other articles rapidly and accurately, and more particularly to means forming part of such a machine for presenting and positioning the tack for setting the button.

This case is divided out of our application for patent for button setting machines, filed May 10, 1915, Serial No. 27,042, in accordance with the requirement of the Patent Office. v

The object of the invention is to provide means for positively presenting and positioning the tack and for using the force of gravity only for delivering the tack to the positioning means and thereby permit the machine to be run in a practical way at high speed.

The invention consists of a tack-feed comprising a raceway having a cut-ofi, a feedtrough adjacent to the delivery end of said raceway and a reciprocating slide in said feed-trough for advancing the tack to the setting mechanism in such way that it is always presented thereto at the proper time relatively to the button feed and in the proper position, as we will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a front elevation of a complete machine embodying the device of this in vention. Fig. 2 is a left-hand side elevation of the upper part of the machine. Fig. 3 is a detail in vertical section of parts of the button and tack mechanism. Fig. t is a perspective view ofv the tack-positioning slide. Fig. 5 is a horizontal section below the magazines or hoppers, on a larger scale. Fig. 6 is a vertical section taken to the right (Fig. 1) of the setting mecha- Serial No. 61,327.

'n'ism and on a larger scale. Fig. 7 is a sectional elevation of the tack holder and plunger. 'Fig. 8 is an edge view or elevation of one form of button which the ma chine shown is designed tofset; Fig. 9 is an elevation of a fastening tack, and Fig. 10 1s a cross-section of a button set on a piece of fabric.

1 is the bed-plate or table, mounted upon 5 legs or frames 2. r,

3 is the main-shaft from which the various moving parts are driven. This shaft maybe and preferably is connected with a drive-shaft a by reducing gearing 5 and 6 for the purpose, among others, of running the machine at high speed. The shaft 4. is

provided with any suitable means, preferconnected with a treadle 13 by a rod 14,

but other suitable means may be used for starting and 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 or gears 5, 6, the main-shaft having the stopping and starting mechanism'applied to it.

The button magazine or hopper15 and the tack magazine or hopper 16 are mounted upon the head in any suitable manner, and

at any suitable angle, and so as to be capable of 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 connectedby the I 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 2i and 25 to a driving pulley 26 on the main-shaft. The pulley 22 is loose on shaft 17 and carries a pawl 27 which engages a ratchet 28 fast on shaft 17. The button hopper or magazine is loose on its shaft but is held frictionally to turn with it by any suitable means, such as the spring 29 and the washers 30, which latter are keyed to turn with the shaft and the nut 31. By these means the button and tack magazines may be turned by hand, independently of the driving pulley 22, so as 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 in any suitable way to turn with it as desired, and we have shown a nut 82 as the means for retaining it upon its shaft.

The buttons are discharged from the mag azine into a raceway 38 depending therefrom, with their hubs outermost, and must be turned for setting purposes, so as to present their hubs lowermost and vertically.

The lowerend of the raceway is intercepted transversely by a reciprocating cut-ofi 84, actuated by a rock-lever 35 pivoted on the head of the machine, 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 arranged the 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 12 at one end, of a size sufiicient to receive 2 the button edgewise, and it is provided with circumferential spur-teeth 13 outside of the casing which are engaged by a toothed rack 44' on a longitudinally reciprocating bar 45 mounted in the headof the machine at the rear of the turner and actuated by a cam 46 on the. cam-carrier 4C7 fast on the main shaft, and a spring 48. By this means the turner is turned with its opening vertical to receive a button edgewise from the raceway 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 theposition 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 outof the toothed end of the turner device and its head works in the opening or slot 42. 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 main-shaft, so that when the machine is running the stem and its head will be given a longitudinal reciprocating movement in the turning device to eject the turned or oted spring or other effective latch 55 en gaging a slotted keeper projection 56 on the casing.

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 to ether at their upper ends so as to be capable of parting or separating at their inturned lower ends to permit the movement there through of the vertically reciprocating setting anvil 59 and the discharge therefrom of the button being set, and these fingers are held in operative relation by a spring 60. The inturned ends of the fingers are undercut at their outer portions transversely to the vertical anvil passage, to form a pocket 61, of substantially the profile of the button, into which the buttons are successively v ejected by the ejector, and by means of this pocket the button is held in the fingers against the possibility as well of misplacemcnt 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 overlap the fingers at their greatest lateral separation in operation. The upper portions of the fingers are cut away to form an intermediate slot 68 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 fingersdown 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. Thefinger-ends are moved by the anvil into a position lower than that of the turner, and then the further descent of the anvil and its consequent ejection of the button cams the fingers apart under resistance of their spring, and the button is in position to be set. After the button is set the anvil is retracted and as it rises and the to normal button-receiving relation to the turner and ejector. This'return movement 7 of the fingers is arrested by the bottom of the slot 66 coming into contact with the emergency finger-opening cam lever 67 This cam-lever 67 is pivoted to the head so as to operate within the slot 66 to separate the fingers whenever desired. When in this position the turner opening or slot42 is in horizontal alinemcnt with the pocket 61 in the finger-ends and the ejector is in positifon to eject the button from the turner" into the pocket in the fingers.

The anvil may be operated by any suitable means, such as a bell-crank lever 68 mounted in the head and connected with the anvil by a link 69, the lever-1 68 being actuated by a connecting rod. 70 extending thence rearwardly and forked to straddle the main-shaft and having a camrroller 71 engaged. by a cam 72 fast on said main-shaft which imparts a compound longitudinal and rising and falling motion to the connecting rod and a rocking motion to the bell-crank lever 68.

The tack magazine has a raceway 7 3 made with a twist so as to receive the tack heads on edge from the magazine and turn the tacks point up before they reach the cutoff 74. This cut-ofi has two fingers 75 having their tips 76 extending toward one another across the raceway, and these fingers are fast on a rock-lever 77 pivoted on the back of the raceway and connected by a rod 78 with a vibrating arm 79 pivoted at 80 to the head and having a cam-roller 81 engaging a cam 82 fast on the main-shaft. In order to prevent breaking of parts in the event of jamming the raceway or cut-off, the rod 78 has a coil 83 formed in it to serve as 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, head down, to a feedtrough 85 arranged in the head beneath and in line with the anvil, and in this feed trough is a slide 86 having the pair of paral-.

lel fingers 87 to straddle the tack point above the back of the head, and undercut to afford a recess 88 to receive the head of the tack and push the tack forward, and an upstanding fin 89 to keep the tack point upright. This slide constitutes the tack ejector. The slide is reciprocated in the feed-trough by means of a bell-crank 90 pivoted on the machine head and having one arm connected by a link 91 with an upstanding lug 92 on the slide, and another arm provided with a cam-roller 93 engaging a cam 94 fast on the main-shaft. The tack ejector eliver the tack :to. fingers 95 pi ote to th head adjacent to the setting die. or plunger 6, hes fingers being yie ding y con c e a y a how spring A st p 98vprevent -t scape of t e tack and a se v to position it on the plunger.

We have herein referred' flwthe cams 82,

. 94 and 103. 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 operativeparts are 'ariable at the pleasure of the machine builder, so long as the efie'ctive cooperation and coordination of parts are concernedand the principle of the invention followed Again, it is to. be noted that we have described the button turner in broad terms, but in or er to i lustrate a suitable turner we have shown in the drawingsone form, which comprises the cylindrical piece 41 having a reduced portion 104 next to the teeth 43 and fitted in a sleeve 105 having a rear extension 106 fixed to the back of the casing, as by screws 107. This cylindrical piece is held in the casing and sleeve by the collar 108 fixed to the reduced portion 104 outside the sleeve. 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 otherwise provided.

The operation would appear to be sufficiently indicated in and by the foregoing. However, it may be briefiy 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 109, Fig. 10, is passed by the operator between the anvil and plunger and arrested momentarily beneath the anvil. The tack 110 is first positioned over the plunger, point up, and held by the fingers 95, and the tack ejector recedes to take its place for the next tack. Then a button 111 is righted, transferred to the pocket in the fingers 57 and carried down by the fingers and anvil toward the tack and the plunger is caused to ascend and pass the tack point through the article Copies of this patent may be obtained for tions repeated. The spring fingers 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.

For a further detail illustration of the construction of the button turner and of the fingers 57, reference is made to the parent case hereinbefore referred to, and for the claims for said button turner, reference is made to our concurrent divisional application of even date, Serial No. 61,326.

What We claim is I 1. In a button setting machine, a tacksupplying mechanism, including a hopper, a raceway leadingtherefrom, a cut-off to discharge tacks one at a time from said raceway, a feed trough arranged adjacent to the delivery end of the raceway and adapted to receive the tacks from said raceway, and a tack ejector slidably arranged in said feed trough and having its leading end adapted to engage a tack and move it forward through said feed trough into position to be set and also having an upstanding fin in the rear of said leading end to keep the tack point upright while the tack is being moved forward, means to reciprocate said tack ejector in said feed trough, and means to receive the tack from said ejector and position it for setting.

2. In a button setting machine, a tack supplying mechanism, including a hopper, a raceway leading therefrom, a cut-off to discharge tacks one at a time from said raceway, a feed trough adjacent to the delivery end of the raceway, and a reciprocating slide operating in said feed trough having terminal fingers adapted to straddle the tack point, an undercut recess below the fingers to receivethe head of the tack and an upstanding fin back of the terminal fingers to hold the tack point upright.

In testimony whereof we have hereunto set our hands this 10th day of November A. D. 1915.
