SPECFICATION forming part of Letters Patent No. 448,569, dated March 1'7, 1891i.

Application filed October 30, 1890. Serial No. 369,831. (No modeld To @ZZ whom it may concern.-

Be it known that l, l-Innvntcn ZNDoaF, a Prussian subject, residing at Rittershausen, in Barmen, Germany, (in Rhenish Prussia) have invented ne7 and useful Improvements ina Machine for Making the Lower Parts of a Button with Vire Eyelets, of which the following is a specification.

'lhis invention relates to a machine for preparing the under parts of buttons, said under parts consisting ot a cap of thin metal andan eye secured to the cap. The attachment ot the eye, Which is formed by bending a piece of wire, is accomplished by inserting the ends 0E the wire or legs of the eye into the cap and bending them over on the inside thereof.

In the accompanying drawings the machine is shown complete and also in detail. i

Figure l is a vertical section alongxm, Fig.

3. Fig. 2 is a vertical section along y y, Fig. 3. Fig. 3 is a plan view of the machine.

Figs. liL and lb show a cap and also a cap united with an eye. Fig. et is a detail viewof a portion of the disk, showing the spur for receiving the button-eye. vieW on the line .a e', Fig. l. Fig. 6 is a detail elevation of the Wire-feeding and eyeforniing devices. Fig. 7 is a central sectional view ot the same. Fig. S is a horizontal sectional view of the cylinder Which carries the punch mechanism. Fig. D is a detail elevation ot' the punch-moving devices.

To prepare the under parts of buttons, the machine contains three parts, the first consisting of an apparatus for making the Wire eyes o, Fig. lb, the second of a device for making the caps c, Fig. l, and the last of the device by which the bending over 0 2 the legs of the eye on the inside ot the cap is accomplished. The motion of these parts is obtained from the shaft \V, journaled in the trame or support et' the machine, and which is actuated by pulley R, Fig. 2, or, if desired, by hand orfoot power.

The construction of the eye, as also the apparatus therefor, is described later on. The uniting of the eye and cap is accomplished as follows: The eye is passed from the eyeforming apparatus onto a spur d. (Shoxvn in Fig. 4L in section in face view and plan vient) This spur d projects from the edge of a disk B, which turns intermittently at equal inter Fig. 5 is a sectional t thereon in Fig. 3.) The disk B is setinto the table A of the machine. The spur d, which occupies the position l, Fig. 3, receives the eye from the eye-forming apparatus. The disk B has its upper face iiush With the top of the table A, and said disk carries siX spurs d at equal distances apart. Each revolution of the shaft XV imparts to the disk B onesixth or a rotation, so that the spurs d, one after another, come to the position l. W'hen the spur atl has received an eye, it is cai'- ried by the next movement to the position 2, the eye having its legs pointing upward and gliding past the inner edge of the recess in table A. Ihile the disk Bis at resta cap is placed onto the eye-legs, so as to occupy the position shown in view II, Fig. lb. On the disk B continuing to revolve the eye and cap come to the position 3, Fig. 3. At this point a descending plunger causes a partial spreading of the eye-legs, so as to bring them tothe position shown iii view III, Fig. lb. Upon a further one-sixth revolution another plunger completely spreads the eye-legs, as seen in view IV, Fig. lb, so as to firmly unite the eye and cap. The following one-sixth revolution carries the complete under part of the button to the position 5, Fig. 3, over an opening O in table A, and a iiat spring or scraper N, secured to the table, scrapes the eye from the spur tl, and the under part-of the button, falling through the opening O, can be carried by a suitable chute to a box or receiver. At 6 the spur is empty, and at l it again receives'an eye from the eye-forming apparatus.

To the under side of the disk B is secured a shaft a,Figs. l and 2, which passes through a thickened part of the table A, and is provided with a ratchet s, engaged by a paWl 7n, mounted on the lever 7i, fulcrumed on. shaft a. A spring t holds the paivlin engagement With the ratchet. As seen in Fig. 5, which is a section along c, Fig. l, the ratchet s contains six teeth equal distances apart, so that the shaft a and disk B can be given one-sixth of a revolution by a corresponding movement ot' lever it. Said lever is held by a spring f in the position shown by broken lines in Fig. 5, so that the paivl 7c lies directly in front of a tooth of the ratchet-Wheel s, and the movement of the lever away from the stop or rest vals lin the direction of the arrow. (Shown /i is caused by a lug 1/ on shalt W, the passage of the lug turning` the lever sufficiently to move the ratchet one tooth or one-sixth of a revolution. After the lug has passed on, the springf brings the lever 7L back to the dotted position, Fig. 5, so that the pawl Zt' passes back of the next tooth, the wheel s remaining stationary the while. lt is thus evident that upon each revolution of the shaft lV the disk B is turned one-sixth of a revolution. To keep the disk securely in its recess in the table A, a spring n, Fig. l, is arranged on shaft a, which draws the disk securely into its recess. Over the disk B the cylinder C is centrally arranged and supported byarm G. The cylinder carries the punch mechanism for punching the caps, and also guides the plungers for spreading' and depressing the eye-legs. The punching mechanism (shown in Fig. 2 in face View and in Fig. 0 in side elevation) consists of a punch or plung'er carried by an arm t', secured to the rod (j, which can reciprocate vertically in the cylinder C, and of a die b, having a central stud or counter-punch b', Figs. 2 and 3, and secured to the table A.

To prepare a cap I place a plate or blank, Fig. l;L ot a proper size over the die b, and the punch is then allowed to drop onto the blank, so that the latter is forced into the die, and provided by the punch b with a hole for the eye-legs or Shanks. The punch Z has a proper hole for the entrance of the counterpunch Z1. The descending force of the punch is caused bythe weight g on guide-rod (/,and the weight is raised by a rod m', running in guides m m. The upper end of this rod rests freely under the weighty. The rod is raised by a bell-crank lever t' i,engaging the shoiilder m2 and swinging on fulcruin e on standard e. The bell-crank lever is actuated by rodp, running in guidep and striking' against levenarxn 2". The 'free end ot' rod p rests against a raised track or elevated rim p2 on the disk E, mounted on shaft W. This raised track has a portion cut away at p3, Fig. l. At one side of this cut-out the track p2 ends abruptly and begins again at the other side with a gradual rise. When the track p2 has been carried with its abrupt end to the rod p, said rod passes into the cut-out and the level' z' t" and rod m are released, so that the weight g and punch t can drop onto die Z) and form a cap. After the passage of the cut-out 213 the incline or gradual rise of track p2acts on rod p. This incline ends in a somewhat less elevated portion of thetrack, so that the punch t at rst is only raised part way and remains a short time partly raised, during which period said punch is turned with its rod g, so that the center of the punch comes to rest over the position Fig. 3, of disk B. The cap, which after its formation clings to the punch t, is brought by this swing' ot' the punch into such position that the hole in the cap rests directly over the Shanks of the eye at 9, and then the punch if is entirely raised by the highestpart of track p9, acting upon the parts p i' L" my', and said punch remains so raised until it again drops into the die. The turning' of the punch from its position over the die b to its position over the eye at 2, Fig. 3, is effected by a lever r, which is so arranged that it can turn on rod g, but does not partake of the i'ise and fall of said rod. For this purpose the hub of the lever has a groove, into which enters a pin 1", secured to cylinder C, and the rod g has a longitudinal groove n', into which enters a stud Won the hub of the lever. It is thus seen that the rod g must follow the rotation of lever yr, while said rod is free to move vertically as the groove n and stud n2 form a movable connection.

To the lever r is connected a link Z, united to the bell-crank lever Z Z2, fulcruined at c. The lever-ai'in Z2 is connected to the rod Z3, running in guide p and actuated by the raised rim or track Zt, located adjacent to track p2 on disk E. The track Z'l consists only of a short elevation, which, striking the tree end of rod Z3, moves the latter, so as to swing the lever Z Z2 and move link Z, so as to turn the lever r. The punch tis thus brought into position" over the die Zi, as seen in Figs. 2 and S, which latter represents a section along rc m', Fig. 2. When the raised track ZA1 has passed the rod Z3, the spring Z5 presses the rod forward or outward and the lever r moves in the opposite direction, so that the punch t comes to position 2, Fig. 3, or over the eye. Then the punch has reached this position, it is entirely raised, as already described. To scrape off the cap from the punch on the ascent of the latter, so that the cap will fall with its hole over the shan ks of the eye, the punch enters a fork w i', Figs. 2 and S, the prongs of which are so arranged that they snugly clasp the punch, and thus scrape the cap oli? the punch as soon as the latter passes from the dotted position in Fig. 2 to its highest position.

'lhe plungers D F,guided in the cylinder C, are intended to spread and fasten down the eye-Shanks in the caps when the latter are in the positions 3 and 4, Fig. 3. These plungers must of course be accurately located overthe points 3 and 4, respectively. rlhe plungers are secured to a common weight ll, which is carried by the rod l, guided centrally to the cylinder. The end ot plunger D is somewhat ground ott at opposite faces, so as to be slightly sharpened to readily enter between and spread the eye-shanks, and the plunger F has its end rounded, so that on striking the eye-Shanks it will bend them over to lie firmly against the inside ot' the cap. The weightearrying i'odl is extended downward through disk B and its shaft, and near its end said rod has a nose T', which is actuated at suitable intervals by an eccentric disk l2 on shaft \V, so as to raise the rod, and after the high part of disk l2 has passed thenose l the rod and weight H suddenly drop.

Figs. l and 2 show the rod I, weight l-l, and plungers D F raised, in which position the nose l is held up by a raised or high part ot' IOS llO

disk I2. lVhen the revolution in the direction of the arrow, Fig. l, has carried this high part past the nose I', the latter suddenly slides down and the weight H, with the plungers D E, falls, so that the latter enters between the eye-Shanks, after which on thcfurther revolution of the disk I2 the plungers are again brought to the raised position, Figs. l and 2. The descending force of the weight H can be augmented by the spring I3, secured to the lower end of rod I and to the connect ing-rod T. The tension of this spring can be regulated by the screw T. The screw s is secured to a side of the weight H, and on the descent oi' the weight the end of screw s strikes upon the cylinder C, so as to take up the lateral jar caused by the striking of the plunger D F.

To properly iixthe disk B in position after each one-sixth revolution,it is provided with six perforations, into which a rod q, Figs. l and .2, enters from below immediately after the passage of the arm a past the lever 7L and after the latter has gone back to -the stop h. For this purpose the rod q rests with its lower end on the eccentric q', mounted on shaft lV. The eccentric raises the rod q at the proper moment; but as soon as the disk B is to turn the rod q sinks into a lower part of the eccentric, so as to pass out of the perforation in disk B.

The apparatus for forming the eyes has yet to be described, said apparatus being shown partly in Figs. 2 and 3 and on an enlarged scale in Figs. 6 and 7. The apparatus contains a plunger S, reciprocating along the ver= tical plate P, and provided at its upper end with a cutter S for cutting off the wire and, a semicircular recess S2. The levers K L swing on fulcrums M M and carry the fingers U. The lever L has an arm L resting on lever-arm K', against which presses a spring K2,so as to separate the levers K L. The pushing arrangement V V V2, Fig. 3, pushes the completed eye from the rod Q onto a spur ot' disk B,and the wire is fed to the eye-forming apparatus by the rollers w, actuated by pulley w and gear-wheels w?. The pulley w' receives motion from pulley fr and shaft wa, Figs. l and 2, and the shaft tra. receives motion from the shaft XV by means of pulleys o o2. The wire o', Figs. 3 and G, for forming the eyes is fed from a suitable supply orbobbin (not shown) between the rollers w and through a suitable hole in the guide-piece S3 until it abnts against the opposite guide-piece S4. The pieces S'1 form a guide or way for plunger S. The portion of Wire between the guide-pieces S3 S4 is cut by cutter S' on the ascent of plunger S, and as this piece of wire rests directly under the rod Q the rise of plunger S will cause the wall of recess S2 to bend the wire about rod Q, so that the wirel ends point upward, as shown in dotted lines in Fig. 6. While the wire piece so bent is in the position just named the levers K L are moved toward one another, as shown by the arrows, Fig. G, to bring the fingers U U together and bend the wire ends about the rod Q, so that the eye takes the form shown in view l, Fig. l. For this purpose the ends of the fingers U are correspondingly formed, so that the wire ends which are pressed together pass one another-that is to say, they come to rest alongside of one another.

The eye-forming apparatus is set into a recess A', Fig.' 3, of the table in such a manner that an end of rod Q is directly in front of that spur d ou disk B which is at the position l.' The other end of rod Q is fastened at Q2. Over the rod moves the pusher V V, formed with circular cross-section at V and four-cornered at V', said pusher being guided in a corresponding gutter of the table A. The round part V passes through an inlay P in plate P, and the free end of part V lies flush with that face ot' inlay P against which the plunger S is held by spring f c. lVhen the part V moves toward the free end ot rod Q, the eye o on such rod is pushed off the rod onto the spur (l of disk B. The movement of part V is caused by the actuator V 2 receiving motion fromdisk E by means of a roller To, which enters a cam-groove E on disk E. The actuator V2 is guided by a channel or slot s e', and the slot s il and pin do form a connection between the actuator V2 and pusher part V. As soon as the roller ro enters the forward part of cam-groove E the pusher VV is moved forward, and when the forward part of groove E has passed on the pusher is moved back. The plunger S and levers K L are moved, respectively, by an eccentric-disk and anA arm L2 on shaft iV. The eccentric-disk strikes a lug S on plunger S, so as to raise the plunger, and when the high part of the eccentric has passed the lug SG the plunger S moves back again. The arm L2 acts on the arm L3 of lever L so as to cause the levers L K to move toward one another.

The co-operation of the various parts is such that at each revolution of the shaft lV a wire eye is finished and fed to the disk B. At the same time the punching apparatus forms a cap and places the latter on an eye. The plungers D F bend over the eye-shanks 4on the interior of the cap, and the rollers it' feed a fresh piece of wire to the eye-forming ap paratns. To secure the proper sequence of operations, the various arms and eccentrics, as also the disk E, are properly mounted on shaft lV.

The punching mechanism for forming the caps can be left out of the machine-that is, the previously-finished caps can be placed by hand on the shanks of the eye in position 2, Fig. Since the putting on of the caps by hand may, however, cause a disturbance in the position of the eye on the spur d and a consequent inclination of the eye-Shanks to- Ward one side or another, the eye must be accurately righted as soon as it reaches the position 3, so that the plunger D will strike beroc ITO

tween the eye-Shanks. For this purpose the machine is provided with a righting device consisting of a slide ch, Figs. l and 3, and an actuatinglever ch, fulcrumed at ch73 and actuated by a lug gc, Fig. 3, ou disk E. The movement of the lever ch presses the slide ch forward, and as the latter has a flat spring ci, provided with a recess ci', the forward motion of the slide will right the eye, since the sides of recess et" engage the eye-shanks at each side and thereby press the eye-Shanks into an upright position, after which the slide is drawn back either by a spring or by a suitable cam-groove on disk E, made to act on lever ch.

What I claim as new, and desire to secure by Letters Patent, is-
