BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 5518,23 1, dated April 14, 1896.

Application filed January 14, 1890. Serial No. 336,876. (No model.)

To aZZ whom it may concern:

Be it known that I, EUGENE H. TAYLOR, of Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Button-Setting Machines, of which the following is a specification.

The object of my invention is the production of a machine adapted to operate automatically to attach buttons to leather or similar material by means of metallic staples or fasteners. Machines for this purpose which are partially automaticthat is, which act automatically after being supplied with a chute or raceway which has been filled with buttons and attached fastenersare now in use, and I am also aware that machines designed to act wholly automatically have hitherto been constructedybut I am not aware that any of the latter class of machines are capable of practical operation.

My machine hereinafter described is wholly automaticthat is, it receives and sorts the buttons by means of proper machinery and also receives and sorts the staples, then brings the two together and inserts a staple in the eye of a button, and finally drives the staple with its attached button and clenohes the staple.

My invention consists not only in the mechanism forperforming each of the necessary operations above described, but also in the combination of such mechanism so as to constitute an organized machine.

I have shown my invention as embodied in the best form now known to me in the machine represented in the accompanying drawings, and the construction and operation of the same will be clear from the following description, in which like parts thereof are designated in said drawings by like letters of reference.

In the drawings, Figure l is a side elevation of the operative parts of the machine, the standard or support therefor being broken away. Fig. 2 is a plan view of the same. Figs. 3, 4c, and 5 are respectively a front elevation, a side view, and a vertical central section of the driving mechanism as also of the button and staple delivery mechanism in the position which the parts occupy just before they present a button to receive a staple, said Fig. 5 being a section on line y y, Fig. 3. Fig. 6 is a front elevation of the same parts, the driverbar being at that point in its upward movement at which the staple-inserting mechanism begins to act. Fig. 7 is a front elevation of the same parts, the driver-bar being very near the end of its upward movement. Fig. 8 is a side elevation of the same parts in the position shown in Fig. 7 and showing a portion of the button-raceway. Fig. 9 is another view of the same parts in slightly changed positions, the staple-inserting mechanism being below the center of its movement. Figs. 10 and 11 are similar views showing the position of the same parts when the button has been Set and the driver is at the lowest point of its movement, and Fig. 11 also shows the next succeeding button in position to be presented to the staple-chute to receive a staple. Fig. 12 is a detail, on a larger scale, showing a staple being inserted in the eye of the button. Fig. 13 is a vertical section on line 03 at, Fig. 12. Fig. 14 is a section on line 2 z, Fig. 15; and Fig.15 is an end view of the staplehopper. Fig. 16 is a vertical section showing the construction of that portion of the front plate which.operates to take the lowermost staple from the staple-raceway. Fig. 17 is a vertical section of the lower end of the guideway, showing the spring-impelled plate,which is notched at its lower end to receive the eye of the button when the button is delivered in the guideway from the lower end of the button-raceway. Fig. 18 is a section on line x :20, Fig. 16; and Fig. 19 is a front elevation of the machine.

'A represents the stationary frame of the machine, which may be bolted or otherwise secured to a standard of proper height and which is of a shape suitable to support the various parts of the mechanism, as shown.

B is the main shaft, which is provided with a suitable pulley for the reception of a driving-belt. On the shaft Bis Secured a bevveled gear 0, which meshes with a beveled pinion cl, fast on a secondary shaft 3', (see Figs. 3, 8, and 11,) which is journaled in the upright portion 6 of the frame A. The other end of this shaft is provided with a crank, on

guide or channel way.

th at means must be provided for taking a butt ton and staple from their respective recepta-j which is journaled one end of the connectingrod f, (see Fig. 1,) the other end of which is pivoted on a pin g, (see Fig. 5,) projecting from the rear of the upper member h of the driver-bar. As the shaft j rotates it will be clear that the driver-bar will be reciprocated vertically. The driver-baris mounted in vertical ways in the piece 7;. on the front of the machine and consists of two members 72. Z, secured together for purposes of adjustment by a bolt on. The lower of these members Z carries at its lower end the driver it, which is notched or cut away centrally to accommodate an upward projection on the crown of the staple, asalso the eye of the button,.and so that it may bear only on. the shoulders of the staple directly above the prongs in a wellknown manner. The driver reciprocates vertically through a grooved channel or guideway, which is open centrally front and rear to allow the eye and head of the button to pro jeet, the eye of the button being substantially at right angles to the prongs of the staple when the driver is acting on the staple to drive it through the material.

:It will be clear that if a staple with a but ton on itbe placed in the .guide or channel way below the driver the downward move; ment of the driver will force them out of the guide or channel way and the staple into the material held against the lower end of the It will also be clean cles, inserting the staple in the eye of 'the button, and placing the staple and its attached button in position in the guideway below the driver in order that the staple may be driven and set.

The! mechanism which takes the staples and buttons from their respective receptacles, guides them to a point under the driver, in serts the staple through the eye of the button, and places the staple and attached but ton in the guideway will now be described.

The buttons are placed in ahopper or receptacle P, (see Figs. 1 and 2,) which is mounted on a rocking arm (1 which can oscillate on the shaft or pin r, so that the hopper P can oscillate in order to move the raceway s, which is secured to it, toward and from the front of the machine. This raceway is provided with two guides t, between which the eye of the button projects, while the body of the button rests against the piece 5, as shown inFig. 4. Theseguides t and piece 8 in fact constitute the raceway and guide the button from the oted at-its upper end at a to the frame of the machine and is provided about midway of its length with a pin 6', which is received in the groove of a cam c, secured on the shaft j. As the shaft j revolves the lever 1 will oscillate and the raceway s will be moved toward and from the front of the machine.

When a button has descended the raceway to the lower end thereof, as shown in Fig. 4, the raceway is moved toward the front of the machine and the eye of the button is caused to project into an opening in the front of the guideway and to lie in said opening diagonally across the guideway, as shown at d, Fig. 12. I11 this position it is presented to one prong of the descending staple.

The staple-hopper is shown at E and is journaled on a stud F, secured to the frame. (See Figs. 1 and 2.) The hopper E is a frustuin of a hollow cone closed at its front and rear ends. The front end has a central aperture, through which a thin strip of metal 9' projects. Said strip of metal is inclined to the horizon and i extends nearly from the rear of the hopper to theplace where the staples are delivered into the guideway, being bent sid ewise at its lower end, as shown in Fig. 2, thus forming the raceway'down which the staples are carried. As the hopper E revolves by the operation of a belt (shown in Figs. 1 and 2) or by any other suitable means the staples are lifted by wings a secured to the inside of the hopper, .as shown, and dropped upon the edge of the guide-strip g, and such of thenras straddle thest-rip will slide down the same by gravity and accumulateat the lower end thereof. In order to prevent their clogging on the strip,the strip may be jarred by means of a spring a, oscillated .bynotches b? on the edge of the opening at the small end of the hopper E. A narrow piece or rod h is placed over the guidestrip g outside the hopper E to prevent the staples from being displaced. The lower end of the raceway g enters a recess 0 in the front plate 70, which recess forms the upper end or mouth of the staple channel-way], leading to the button. This plate prevents the staples from passing off the raceway until they are one by one picked oif. The manner in which the lowermost staple is picked off or taken from the raceway and placed in the mouth or upper end of the channeLWayj will be clear upon reference to Fig. 16, which shows the raceway with some staples at its lower end, as also a section of the frontplate 7c, in which the channel-wayj is out. The frontplate reciprocates vertically, as will be hereinafter described, and, considering it to be in the position shown in Fig. 16, as it moves upwardly the beveled projections f pass up bet-ween the lowermost staple on the raceway g and the staple next above it and separate the lowermost staple from the adjoining one, at the same time preventing the adjoining staple and those above it from passing farther down. As soon as the downwardly-proj ectin g beveled portion has passed above the crown of the staple the lowermost staple drops into the recess 0 which forms the mouth of the channel-wayj. )Vhen the front plate passes downwardly again, carrying the projection f below the staples on the raceway g,the staples slip down a distance equal to the breadth of one staple and are prevented from falling by the projection giwhich descends with f This is an ordinary way for picking out articles one by one from the bottom of a raceway, and other known ways for performing the same duty may be substituted therefor. On the nextreciprocation of the plate 7t the operation is repeated, and thus the staples are removed one at a time from the raceway gand drop into the channel-way j. This channel-way] is an upwardly-extending branch of the guide or channel way in which the driver acts, and the eye of the button,when in the position shown in Fig. 12, (and heretofore described,) lies across this race way, with the hole in the eye of the button in a position to receive the uppermost prong or leg of the staple.

The device for placing the staple which has been dropped into the channel-way through the'eye-of the button consists of a finger n, which is actuated by an arm or follower is, pivoted at its upper end to a lever Z, which is journaled at one end to the vertical front plate 70 of the machine. v This lever is operated in one direction by a striker 6 which is secured adjustably to the front of the driverbar Z. (See Figs. 3 and 5.) As the driver-bar moves upward the striker e comes in contact with the projecting tail of the lever Z, forcing this tail upwardly against the pressure of the spring on and throwing downwardly the other end of the lever and the arm 70, while, when the driver-bar descends, carrying down the striker, the spring m operates to reverse the movement of the lever l and to raise the arm 7;. The lower end of the arm 7c carries firmly secured thereto a finger n, which projects downwardly and rearwardly from the lower end of the arm or follower It, and thus projects into the channel-wayj. This finger rides against the lower side of the channelway j, is oscillated up and down by the movement of the lever Z, and when it comes in contact with the staple in the channel-way forces it downward and through the eye of the button, the end of the movement of finger 77.

causing the button to turn so that its eye will front plate, serves to hold the tilting plate normally in an upright position, as shown in Fig. 3; but as the arm 70 in its downward movement comes in contact with the tilting plate (see Fig.7) the plate is tilted to one side and carries the arm or follower in a direction substantially across the face of the machine.

Fig. 7 shows the arm in contact with the pivoted tilting plate q just after the plate has begun its movement.- On its upward movement the arm is is thrown sidewise by means of a spring (1 fast at its upper end to a pin on the lever Z and at its lower end so bent as to bear on the arm and cross it sidewise away from the center of the machine, thus causing the finger n to follow the lower edge of the channel-way].

For the purpose of agitating the buttons in the hopper P, I provide inside the hopper a brush or equivalent device secured to a shaft 8', one end of which projects through the rear of the hopper and has a beveled end provided with a single tooth or'projection, which is received in a recess in the correspondingly beveled end of the shaft t, which is journaled in the rock-shaft arm q. (See Fig. 1.) To the shaft 16 is secured loosely a pin it, (see Figs. 2, 5, &c.-,) which projects through a hole in the block 4) on the upper end of the vertically-moving plate w, which is in fact a continuation of the driver-bar. As the driver-bar reciprocates the extension 10 will be moved vertically and the shaft i will be rocked through the agency of pin a, thus rocking the shaft 8 and moving the brush in the hopper P so as to agitate the buttons therein. The staple-hopper E is given a rotary movement by means of a belt c (see Figs. 1 and 2,) which passes around the hopper in the groove cut in the exterior thereof, thence over grooved idle-rolls b and thence around the grooved boss or hub c of the driving-pulley. By this means the hopper is revolved when the main shaft is driven.

The front plate It is slotted vertically, the slot being provided with grooved ways to receive the driver-bar, which is set therein and which has a vertical movement independently of the front plate It. It is necessary that the staple and attached button, which are located in the guide underneath the driver and are in position ready to be set, should be placed near to or upon the surface of the material upon which the button is to be set. Otherwise the staple would not be guided as it is driven into the material, and it is also necessary that the guide which holds the staple should, when the material is being placed under it, be a sufficient distance from the anvil against which the staple is clenched to permit of the m aterial being freely in serted and withdrawn. To accomplish this object, I make the front plate vertically movable, so that after a button and staple are in position below the driver the guideway in which they are located and which consists of the lower portion of what I have called the front plate 70 is moved down .IIO

to bring its lower end into contact with the material in which the button is to be set. The driver then descends, driving the staple, after which the front plate 70 and driver move up together by friction of the driver-bar there-j on, as hereinafter described, the front plate, when it has completed its upward movement; stoppingand the driver continuing in its up; ward movement. The upwardmovement of the front plate is stopped by the bottom of the verticalslot of in said plate coming in contact with the end of the staple-raceway g, the driver continuing its upward movement, as previously stated. The frictional contact beal tween the driver-bar and the face-plate 70, by which the movement of the plate is effected; is produced by clamping the plate betweenj the flanges or side portions of the upper mem-; ber h of the driver-bar and the extension w,

by means of bolt-g, that, portion of the bolt which extends forward and passes through the driver-bar, plate 70 and extension 40'. beingof less diameter than the rearward por-j tion thereof and being provided witha nut in front of the extension 10, as shown. As will be clear, the driver-bar, plate 7c and eX-.

\ tension 20 may be clamped securely between :anvil 7L2 below or the goods resting thereon and upwardly by the contact of the bottom of the slot (1 with the end of the raceway g. The exact time in which this movement is effected is not essential, and in the machine represented in the drawingsl have shown it as produced by means of the friction of the driver-bar extension w against the plate 70, :as described. The operation of the driverbar and plate relatively to each other is as follows: The parts being in the highest position, (see Fig. 5,) the connecting-rod f begins to descend and carries the driver-bar and plate with it. They descend together until the lower end of the plate rests on the material on the anvil. The face-plate 70 then rests, and the further movement of the connecting-rod f moves the driver-bar down relatively to the plate is, thus causing the driver to set the staple and button. At the time the button is set the connecting-rod f has reached the lowest point of its movement and begins to rise, and during the first part of its upward movement the plate 70 and driver rise together until the bottom of the slot a in the plate 70 is in contact with the end of the stapleraceway g. Then the upward movement of the plate 70 is arrested, and the further upward movement of the connecting-rod f carries the driver up to its highest point.

Vhen the lowermost button in the raceway s is carried rearward and its eye thrust into the opening made at the upper end of the guide to receive it, (see Figs. 6, 7,and 8,) it is held in that position by the raceway 3 until ment of the raceway s toreceive the prong of the staple, it lies directly in the path of the driver, and it is necessary to provide means for steadyin g the button-eyewhen it is placed in that position which shall act to steady it until the .prongof the staple-is inserted in it,

and which shall also be movable, so that it may not prevent the driver from coming in contact with the staple which rests in the eye of the button. To attain this object, l provide a plate 72/ pivoted at its: upper end on the front plate 7a,.as shown in Figs. 5 and 17.

The pivot of this plate is immediately behind the driver-bar, and a spring 7' is set behind the plate in a recess in the block f the front end of the spring bearing on the back of the plate. This spring tends to throw the plate forward, and as the driver moves up after a button is set past the lower portion of said 'platetheiplate is thrown outward orforward and when the driver is in its raised position (at which time its lower end is opposite or slightly below the pivot of the said plate 7L5) the lower end of the plate is farther forward in position to receive the eye of the next but ton. The shape of said plate, viewed from the front, will be clear from Figs. 6 and 7 and on a larger scale in Fig. 12, it being inclined at its lower end and provided witha notch 70 to receive and steady the eye of the button. As will be clear, the downward movement of the driver presses the plate h back into a vertical position, or substantially so, out of the lineof the driver, thus allowing the driver to pass down and set the button. The lower end of the plate h is inclined, as above stated,

and forms one side of the channel-way down which the-staplepasses when it is thrust through the eye of the button, so that this plate not only performs a function with relation to the button, but also with relation to the staple, serving asa guide thereto while the staple-prong is passing through the eye of the button.

At the lower end of the button-raceway s a spring a is provided, secured to the under side thereof and curved at its lower end, so as to prevent the button from falling out of the raceway. After the button has been delivered in position and the prong of the staple has been thrust through its eye the driver descends, forcing the button and staple downward, and the raceway .9 moves back, and the button is pulled out of the lower end thereof, this spring a yielding to allow the button to escape. The lower ends of the guide-pieces t, between which the eyes of the buttons pro ject, may yield slightly, being of thin material; but I do not consider this essential.

The anvil 71 is of common construction,having depressions in its face to turn and clench the prongs of the staple, and is mounted on an arm k projecting from the upright portions of the frame.

lhe driving-pulley is, by preference, so mounted on the main shaft by means of a toothed clutch mechanism of common construction that the machine may be quickly stopped and started by depressing a treadle which operates a shipper. As will be obvious, any form of clutch and shipper mechanism may be employed, and this feature is not essential.
