Filed April 8, 193l y An Patented Mar. 14, 1933 UNITED STATES PATENT OFFICE FREDERICK H. PETERSON, OF WATERTOWN, CONNECTICUT, ASSIGNOB TO THE PATENT BUTTON COMPANY, OF WATEBBUBY, CONNECTICUT, A CORPORATION 01' CONNECT- ICUT BUTTON ATTACHING MACHINE Application filed April 8,

My invention relates to new and useful improvements button attaching machines, and more particularly to the jaws and jaw operating mechanism that retain the tack or button fastener in position while the plunger forces a button head down onto the fastener, so that the fastener, in turn, will pierce the material to which the button is to be attached and jam up within the button head to complete the assembly.

The present application in its broadest aspects is similar to the type of button attaching machine shown in Patent, No. 1,567,882, granted to Franklin R. White, on December 29,1925.

In that patent, the jaws and their mechanism are similar to the construction shown in the patent granted to Franklin B. White on June 17,1924, and numbered 1,497,819.

In the form of jaw mechanism shown in that construction, it was necessary to have a certain bridge, which was attached to the jaw holding sleeve which, with the finger attached to the elbow, raised the attached button out of the jaws, so the operator was enabled to run through (that is, to attach one button after another without stopping the machine). With this new device, both the bridge and lifting finger are done away with and removes every chance of the operator catching the garment and misplacing buttons, causing delay.

The present invention has to do, therefore, with a new form of jaw mechanism and a different arrangement of certain parts of the machine, whereby the jaws are spread open as the button is attached, these jaws remaining open until the plunger has returned for substantially onethird of its initial upward stroke to thus provide plenty of time for the operator to move the cloth with the attached button from directly over the jaws and from beneath the plunger.

Still another object of the invention is, to provide a novel type of jaw mechanism wherein not only will the jaws remain 0 en while the plunger is making one-third 0 its upward stroke so that the operator will have plenty of time to move the cloth, but furthermore, should the operator fail at this 1931. Serial No. 528,680.

time to move the cloth, the jaws, when closing, will force the cloth with its attached. button slightly upwardly, so that as the jaws again spring together they will not or cannot possibly grasp the head of the fastener that has just been forced into the cloth and up through the button head.

Still another object of the invention is to provide a button attaching machine wherein the jaws that encircle the tack or fastener will tightly hold the same during a part of of the downstroke of the main plunger. Also, as the button head is forced from its receiver down onto the jaws, the jaws are sprung open by the button head and are automatically, by a mechanism to. be described, forced down into a lower plane and out of the way, where they remain until the plunger has passed through one-third of its return upward movement. This gives the operator plenty of time to reposition the cloth for the reception of a new button. Again, should the operator fail to remove the cloth, there is no danger of'the jaws, when rising to their normal plane, to again grasp the tack of the already attached button, but on the other hand they will force the cloth and attached button upwardly and beyond the gripping jaws.

Still another object of the invention is to provide a jaw mechanism that is synchronized with the movement of the plunger, so that after the plunger has descended substantially one-fourth of its stroke, a cam action will come into effect toput a downward pressure on the tack or fastener gripping jaws, that is, on the carrier ofthe tack gripping jaws. When the button is finally forced down on the fastener, the carrier of the jaws, now under a heavy spring pressure, will, with its jaws, be quickly forced to which normally holds the jaw carrier and jaws in their upper position. This greater pressure causes the jaws and their carrier, when the jaws are unlocked, to snap down entirely away from the tack, all of which will be more fully described as the specification roceeds.

With these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts, as

pointed out in the claims.

Referring now to the drawings showing a preferred embodiment. Fig. 1 is a side elevation of the improved button attaching machine showing the plunger in its uppermost or normal position and showing the tack or fastener holding jaws in their closed or normal position;

Fig. 16 is a bottom plan view of the lever for o eratin the jaw carrier.

Be ore re erring specifically to the several views, it will be understood that only that much of the mechanism of the button attaching machine is shown as thought nec- 05 essary to illustrate and describe the invention and to show how the tack jaws are operated and synchronized with the stroke of the plunger. The details for the movement and synchronization of the tucker slide and lock, the ratchet mechanism for the hoppers containing the buttons and button fasteners, and many other details of the machine shown in Patent, No. 1,567,882 are not mentioned or only inferentially mentioned or briefly described.

Referring now more particularly to the several views and to Fig. 1 for the moment, there is shown a metal base or table 1, from which extends the curved upright arm 2 integral with the base and slotted, as at 3, the slot extending from near the base to the upper end of the arm, where it is, in turn, made to form a bearing 4,

in which there is a bushing 5 and in which operates the die or plunger 6. This plunger is slotted at its upper end, as at 7, to receive the connecting link 8, while the other end of the link is secured to the outer end of the main oscillating lever 10, the latter being fulcrumed, as at 11, in the upright arm 2, as may be seen in Figs. 1 and 2.

The lower end of the oscillating lever 10 has the bearing 12 for the reception of a connecting rod 14: (Fig. 1). Said lever may be oscillated in the manner shown in a re vious patent granted to Franklin R. Whiteon December 2, 1913 and numbered 1,079,968.

As may also be seen in Fig. 1, there is a magazine or hopper 15 for holding and sup- 13c -ent invention,

plying the tacks or button fasteners which I are fed down a chute (not shown) to a tucker slide 40 (see Fig. 3), where they are forced, one by one, onto a small head or block 16 which is the upper art of an anvil post 17, where the tack or utton, fastener grippin jaws hold the same while the button hea is being forced thereon. It is these tack holding jaws, a carrier for the same, the anvil post just mentioned, and a cam mechanism for operating the jaw carrier and its jaws that form the gist of the presall of which parts will be described in full as the specification proceeds.

The tucker mechanism just above referred to is shown and described in detail in the patent granted to Franklin R. White on December 29, 1925 and numbered 1,567,882.

As far as the specification has proceeded, the device is similar to the patent just above referred to, to wit, 1,567,882, with the exception of the arrangement of the jaws 18 and the anvil post 17.

Going back for the moment to the other general parts of the machine so that the synchronization of the lunger 6 with the action of the jaws may e understood, there is shown a hopper or magazine 96 for holding the button heads. There is also a ratchet mechanism 96 that is operated by a rod 97, which is connected to the main operating lever 10. The specific manner in which this hopper is rotated with each movement of the main oscillating lever 10 is of no importance to the understanding of the present invention and, therefore, is not described.

Now, there is a second oscillating lever 30, as may be seen in Figs; 1 and 2, and it is the movement of the main lever 10 that actuates this irregularly-shaped oscillating lever 30. The latter lever is provided with a slot 31 in which travels the pin 32, which pin 32 is fastened to the oscillating lever 10.

At the lower end of the second oscillating lever 30 is the yoke 28 connected to the pitman 26, which pitman, in turn, is fastened to the bell crank or tucker lever 33, which latter is the timing element for a number of the parts of the machine.

The above pitman, yoke, and connections are similar to the construction shown in the patent to White, No. 1,567,882 above referred to.

It is the movement of the bell crank 01' tucker lever 33 which operates the tucker slide 40 to advance the tacks or button fasteners onto the block 16, as the tucker lever 33 is slotted at its outer end, as at 33', to.

' of the buttons engage the downwardly extending pin 34, which is a part of the tucker slide 40.

Asheretofore mentioned, a detailed description of the tucker slide and the manner in which it is synchronized with the feeding is not thought necessary and can be seen in detail in the patent granted to Franklin R. White on December 29, 1925, No. 1,567,882.

There will now follow a short description of the means for holding the buttons which are acted on by the movement of the main plunger or die.

Referring again, therefore, for the moment to Fig. 1, there is shown a button chute 35, which leads from the magazine 96 to beneath the plunger or die 6. There will also be seen the arm 90 which is ivoted, as at 91, the forward portion 92 of the arm extending in an angular relation and having the jaws 93 mounted thereon. These are not the jaws, however, that form the gist of the present invention and should not be confused with them. In a like manner, a supplemental pair of jaws 94 is shown in connection with the jaws 93 for preventing the button from rebounding from the jaws 93 and neither should these jaws be confused with the jaws that form the gist of the invention.

It may be mentioned in a general way that when the main oscillating lever 10 is raised, it not only causes the plunger or die 6 to push the arm 92 with its button and jaws downwardly, but it will also cause the oscillating lever 30 to move and, in turn, through the yoke and pitman move the tucker lever 33 which, in turn, will force the tucker slide rearwardly behind the tack escapement (not shown), so that when the oscillating lever 10 is again lowered, the tucker slide on its return movement will force the tack'or button fastener out onto the anvil block 16 to be clutched by the jaws 18. The operation of the lever 30 also rotates the magazine 96 and liberates a button and performs other operations that need not be mentioned at this time.

Now, understanding the general operation of the machine, reference will be made to the manner in which the tack holding jaws are formed and operated, and the cam mechanism synchronized with the strokevof the plunger.

It will be understood that where the word tack is used, it is used in its broadest sense to cover a tack or other form of button fastening member.

First, referring to Fig. 5, it will be seen that the tucker lever 33 has the cam 36 thereon, which cam has a hardened steel face 37 pinned thereto.

This tucker lever 33 is substantially in the form of a triangular plate and has its apex slotted to encircle the pin 34 for operating the tucker slide.

' As also heretofore mentioned, to this plate or tucker lever 33 is connected the pitman 26, so that a movement of the oscillating lever 30 may actuate this tucker lever. There is also a rod 99, a fragmentary portion of which is shown in Figs. 3 and 4, that extends up to the hopper which holds the tacks for imparting a ratchet movement to the hopper, so that the tacks may be liberated to the tack chute..

However, the part of the tucker lever which is of most interest is the cam 36 formed near the rear end thereof, as may be seen in Figs. 3 and 4, because as this plate or tucker lever is revolved from the position shown in Fig. 3 to that shown in Fig. 4, it will, besides operating the tucker slide, cause a small lever 41 to be operated, which lever 41 places the jaw carrier under pressure to thus lower the carrier and jaws, when the jaws are unlocked from the anvil, as will be shortly described.

As may be seen, the tucker lever 33 is partly cut-out on its under surface, as at 38, to receive the handle 39, so that this tucker lever 33 may be hand-operated in case a tack becomes jammed in the tucker slide. This feature is shown and described in full in patent, No. 1,567,882, above referred to.

Referring to Figs. 10 and 15 for the moment, there is shown the cam lever 41 which is formed of the two parts 42 and 43, the parts being pivotall oined about the pin 44. The heel 45 is slightly rounded to provide as little friction as possible in riding up the hardened surface 37 of the cam 36 formed on the tucker lever 33. The nose or forward end 46 of the cam lever 41 projects over and normally rests on the vertical movable jaw carrier 17, which is in the form of a sleeve which travels on the anvil post 17, as may be clearly seen in Figs. 11 and 12. This carrier will be described shortly in detail.

The lever part 43 has the little upwardly extending lug 47 near its forward end, while a projection or lug 48 is on the rear portion 42, so that a small compressible spring 49 may be mounted on a pin 50, which extends between the two lugs. The pin 50 and the spring are assembled and assisting their assembly is the small nut 51, which is screwed up to the shoulder or lug, after which a check nut is placed in back of the same.

The pin will, of course, be provided with the little integral nose 52, while a collar 53 may be seen at the rear end of the spring. The nose will fit within a slight depression (see Fig. 10) in the forward lug 47 of the lever. The pin, with the spring 50 under heavy compression, is fitted between the two parts, and it will be readily understood that a tightening of the nut will increase the compression of the spring but loosen the compression between the two parts of the lever, while a forward movement of the pin will tend to force the two parts of the lever slightly apart, there still being plenty of compression in the spring.

There is, however, very little play between the two parts of the lever, as the shoulders of the tongue and groove connection, shown at 44, (Figs. 10 and 16) are so cut that the parts will abut with but a slight relative movement of one part to the other. The purpose in having these two parts of the lever slightly adjustable, however, is so that when this cam-operated lever forces down the jgw carrier and jaws, the lever will not brea before the jaws are unlocked, and also any sudden shock may be dissipated in the spring rather than possibly snap the lever.

Still referring to Fig. 10, there is seen a coil spring 54 under the carrier 17 to normally hold the carrier in its upper position, this carrier fitting, over the anvil post 17 which latter fits within the bore of the forward end of the table. It will be understood that when the tucker lever 33 is operated from the position shown in Fig. 3 to the position shown in Fig. 4, through the movement of the oscillating levers 10 and 30, the heel 45 of the lever 41 rides up the cam 37. The pressure of the lever 41 on the carrier 17' will now be far greater than the upward pressure exerted by the light spring 54. Thus, when the jaws are spread apart, that is, unlocked from the anvil, as will be shortly described, the carrier will be forced rapidly downward.

In Patent No. 1,497,819 heretofore referred to, a certain form of tack holding jaws was illustrated and referred to, which jaws were fitted on a carrier somewhat similar to the present carrier, but the jaws had to be moved out of the way by the operator moving the cloth. In the present application, however, the jaws are forced apart and unlocked by the button being driven on the tack and are then forced downwardly by the cam and lever action, remaining in this lowered position for a certain interval of time, to wit, about one-third of the upward movement of the plunger, as will also be shortly described in detail.

Referring now more specifically to the anvil post and the jaws, it will be seen that this post 17 has the anvil or head 16 at the top thereof, the top surface of this head being shaped slightly, as at to accommodate the curvatnre of a tack or fastener head. It will also be noticed that on the opposite sides of this anvil and spaced slightly from its top surface are the two locking grooves 56. This anvil, of course, is directly beneath the main plunger 6.

Slidingly mounted about the post 17 is the carrier 17' which has the small jaws 18 pivotally mounted therein. It might be mentioned that forming a part of this carrier is the front upright 57 and the rear upright 57', and to these uprights are pivoted the operating between jaws 18 by the little pivot pins 58, these jaws the two uprights, as may be seen in the several views.

These little jaws 18 are also each provided with a little notch 59 in the front faces of their stems, so that the respective ends of a s ring or resilient member 60 may fit within t ese notches 59 to normally hold the jaws in the compressed osition. There is also shown a spring 1101 er 61, which is attached to the upright 57 mounted on the carrier 17', which holds this compressible member in position, as may be seen in Figs. 1 and 2. This little spring carrier is also illustrated in detail in Patent, N 0. 1,497,819.

Referring again for the moment to the jaws 18, it will be seen that on the inner surfaces of their stems they are each provided with a little nib 62 which is designed to normally restwithin the grooves 56 that are formed within the anvil 16. They are shown in their normal locked position in detail in he jaws at their respective noses are slightly indented or nicked (see Figs. 3 and 4), as at 63, so that when a tack 64 is forced into the jaws by the tucker slide 40 and the jaws are closed the recesses 63 will encircle the prong of the tack to hold it rigidly in position.

As may be clearly seen in Figs. 6 and 7, the nose 46 of the cam-operated lever 41 rests on the upper surface of the jaw carrier 17 that carries the jaws 18 just referred to, to force the carrier and the jaws downwardly lwhen the button is jammed down on the tac It will be understood that when the carrier 17 is in its normal position, the jaws 18 will be in the position shown in Figs. 1 and 3, the jaws will tightly grip the tack 64, which is resting on the anvil 16, which tack has been forced by the tucker slide out onto the anvil, and the jaws will be locked with relation to the anvil.

Referring to Fig. 14 for the moment, wherein the carrier is shown in perspective, it will be noticed that in the left upright 57 there is formed the keyway or slot 65, which is adapted to slidingly fit about the front 66 of the anvil head 16 to thus prevent the carrier 17 from revolving or moving out of its proper vertical alignment. Also, the rear upright 57 of the carrier is desi ned tofit within a groove of the tucker mec anism, as may be seen in Fig. 12 to thus further steady the carrier in its vertical movement.

In Figs. 11 to 15 inclusive, the anvil post and the anvil, as well as the carrier, are

shown in enlarged detail with the jaws removed, so that the detailed construction of this mechanism may be more clearly understood.

The lower portion of the carrier 17 is circular and then tapers inwardly and down be seen in the wardly, as at 67, as also ma several views, while the li t spring 54, as will be understood from the several views encircles the post 17 and extends up beyond the tapered portion 67 and rests beneath the forward and rear uprights of the carrier.-

Operation Supposing there is a button within the jaws 93 on the button receiver and directly beneath the plunger 6 and presume there is a tack 64 resting on the anvil 16. The cloth to which the button is to be attached will be placed directly over the jaws and a clutch (not shown) operated which will, through a rod (not shown) move the main oscillating lever 10 upwardly. This will start the plunger in its downward course and will also move the oscillating lever 30, which lever, it will be remembered is connected to the bell crank or tucker fever 33.

After the plunger 6 has descended about will bear downwardly on the carrier 17.

The heel of the lever will ride up the cam to its top surface, and the plunger 6 will have passed downwardly and forced the button B down on the upper surface of the aws 18 and also will have forced the button head on the tack 64. Furthermore, the tucker slide is driven rearwardl so that it will drive another tack forward y when the tucker slide again advances.

As the button head presses on the beveled upper surface of the jaws 18, the cloth and the button head will force the jaws apart until the little nibs or projections 62 are forced from their recesses 56 within the anvil, and as the nose of the cam lever 41 is hearing with great force on the carrier, the moment the aws are unlocked from the anvil the carrier will be rapidly forced downwardly from the position shown in Fig. 6 to the position shown in Fig. 7. It will be remembered now that the lever 41 has ridden up the cam 36 and will be at rest on the top surface thereof.

Now, the tack will have been driven through the cloth and up into the button head and the button properly attached to the cloth. The main oscillating lever 10 will now be in the position shown in Fig. 2.

Looking for the moment at Fig. 2, it will be seen that the main oscillating lever 10 will have its pin connection with the oscillating lever 30 travel down the slot 31 from the full line position to its dotted line position before the oscillating lever 30 starts to move, as the main lever is pivoted, as at 11,

. and the radii from the dotted line position the cloth and the plunger moved considerably above the jaws 18, so that there is plenty of time during this upward movement of the plunger for the operator to remove the cloth and the attached button. Now, after the oscillating lever 10 has lowered to the dotted line position of Fig. 2 and continues in its descent, it will start to move the lever 30 and this, in turn, will tend to swing the tucker lever 33 again toward its normal position, the tucker slide advancing a new tack. The little heel of the cam operated lever 41 will start down the face of the cam and the pressure thus being relieved from the carrier by this operating lever will allow the spring 54 underthe carrier to again raise the carrier and its jaws 18. The jaws will now ride up the sides of the anvil, as shown in Figs. 8 and 9, and as the jaws rise they will naturally push on the under surface of the cloth. If the operator has failed to move the same and as the jaws continue to rise, due now to the pressure of the spring 54 under the carrier, and there is no pressure being exerted on the cam lever, they (the jaws) will assume the position shown in Fig. 9. Also, due to their spring action, the jaws will snap together when they have reached their uppermost position and the nibs 62 will again engage the slots and look within the same, and the jaws will hold another tack tightly on the anvil.

As shown in Fig. 9, there is no danger of these beveled jaws grasping the head of the tack or fastener just driven through the cloth, as the cloth, being pushed upwardly by the jaws, will cause the tack head to be lifted slightly above the noses of the jaws.

The jaws are now closed and, as mentioned, the lever 41 descends to its final position, the escapement for the tacks has operated, and the tucker slide will have forced a tack out onto the anvil 16. The slide will extend between the two jaws to push the tack into the little recesses formed in the ops of the jaws, where it will be tightly clutched until the 'next button is driven down thereon. In the meantime, of course, another button head will have been liberated down the button chute, so that the machine is ready for a successive operation.

Thus, it will be seen that by providing a cam face on the tucker lever 33 at the desired location thereon, and by synchronizing the several parts, as heretofore explained, the plunger may descend about one-fourth of its stroke before the cam-operated lever begins to ride up the cam surface to exert a downward pressure on the jaw carrier with itsjaws, and likewise the plunger may return through a part of its upward movement before the cam begins to ride from beneath the cam-operated lever. Thus, the jaws will remain in their open position for about onethird of the upward stroke of the plunger before the jaws again snap shut, which will give the operator plenty of time between strokes to move the cloth with the attached button.

Furthermore, should the operator fail to remove the cloth, the little jaws in their upward movement will bear against the cloth, so that there is no danger of the jaws when they do snap shut to again grasp the head of the fastener of the attached button.

It will be noticed that the little cam-operated lever is away from the cloth so as not to hinder the operator and provides plenty of time for the operator to remove the cloth,

nor can the attached button jam should the operator be careless.

I have shown a coil spring in the operating lever cam, but I do not wish to be limited to the exact form of spring here illustrated, nor to the exact construction of the lever 41, as other similar levers and springs might be utilized without departing from the spirit and scope of the invention.

The machine, as illustrated and described above, has given very eflicient service and makes it possible for less-skilled operators to use the machine than might otherwise be necessary.
