BUTTON-ATTACHING MACHINE.

Application filed March 21, 1913,

To all whom it may concern:

Be it known that we, Pros BAMMER, a citizen of Germany, (who has declared his intention to become a citizen of the United States) and THEODORE GENsMER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have inventedcertain new and useful Improvements in Button-Attaching Machines, of which the following is a specifica tion.

' Our invention relates to machines for attaching buttons, as to shoes or other objects ready for use, machine in which the buttons are successively supplied by the operation of the machine with wire, which, by further operation of the machine being severed into required lengths, one for each button, is formed into staples, which are by the machine driven, one by one, into place and clenched to secure the buttons, respectively, in desired position.

Heretofore, machines of that class have been comparatively complicated, expensive to manufacture, liable to breakage, and to get out of order, and expensive to repair.

From among the objects of our invention the following important ones are selected for enumeration.

One object is to reduce the cost of manufacture by reduction of the parts of the machine. Another is, by said reduction, to simplify the operation of the machine. A third is to reduce both liability to breakage and the expense of repairs. A further object is to add to the certainty of the proper operation of the machine, and to practically eliminate any tendency toward deterioration of the operative efiicieiicy of the mechanism in consequence of wear. By our invention also, we provide means for facilitating a supply different sizes to the machine.

Other objects will be apparent from the following specification, constitutes our invention will be described in detail and succinctly set forthin the ap pended claims.

In the accompanying drawings, Figure 1 is a side elevation of one form of et-nbodiment of our invention, showing its parts in normal position at rest, a portion of the standard being broken away.

Referring to the numerals On the drawings, 1 indicates, byway of-illustrationof any suitable base, a tripod which carries a stand 7 I supporting member 3 for the distinctive mechanism of the machine.

The member 3is, for convenience only, made to constitute a table, but that feature of it has no functional significance. Its function is that of an assembling member to support the fixed parts in operative relationship to the movable parts of the machine proper, and to that end it carries a case 13 removed a distance, sufficient for the aceommodation of other parts, from an extension tube 4 with which, in connection with the preferred tubular standard 2, the member 3 is, preferably, provided.

The tube 4 serves as a protective covering to the upper end of a reciprocatory rod 10, and affords, if so used, a suitable guide support to said rod, which for the purpose may be provided with a head 5 that makes a fit with the bore of the tube and so as to slide snugly within it. The head also affords abutment against the shoulder 6 which it defines about the end of the rod, for a spiral spring 7 that is seated as upon an annular collar 8 to the rod that is secured as by screw threads into the end of the tube 4. The spring 7 exemplifies any suitable means for the yielding uplift of the rod 10, and its particular shape as well as its location within the tube 4 are matters of mere mechanical preference and discretion, to which our invention is intended in no wise to be limited.

The rod 10 may be actuated against the force of the spring 7 by any preferred means, as for example by foot power which a pedal lever 12, pivoted to the tripod and intermediately to the rod as indicated at 11, is adapted to apply.

To the head 5 of the rod is fixed an actuating bar 17, upon whose motion toward and from the member 3, the movements of all the working parts of the machine are, preferably, made to depend.

The primary function of the bar 17 being to operate mechanism to make and then to set a staple, it is next in order to refer to the member 15 which is operatively carried by and preferably within the case 13,

and Whose chief function is to bend into the form of a staple a section of wire supplied to it. To this end it being essential only that the member 15 and case 13 be made relatively movable, it is preferred that the former be movable and the latter be fixed with respect to the member 3, through which they are assembled.

As shown in the drawings, the member 15 is bifurcate and reciprocatory within the case 13, but both its bifurcation and its direction of motion are matters of preference only. With this provisory statement of what is essential in the member 15, it will be, for convenience, hereinafter regarded as of the preferred form illustrated unless otherwise indicated and be designated the staple-bender. Proceeding accordingly, the staple-bender is loosely connected to the bar 17 as by a guide rod 16, shown as fixed tothe member 15 and working in a bearing provided for it in the bar. From the bar 17 the staple-bender derives motion, during its first stage of movement from a link 49,.

that is pivotally secured to and preferably pendent (compare Figs. 3 and 8) from the bar 17 and afterward from a yieldingly interposed expansive spiral spring 18 coiled about the rod 16. 7

Between its legs the staple-bender l5 preferably carries an independently reciprocatory staple-driver 19, which is preferably feathered to the member 15. ers are preferably provided on the part 19 with correlative grooves 47 in the legs of the part 15 (see Fig. 12) for the reason that in that way the grooves are made to perform the additional function of receiving and guiding the legs of the staple when formed, as hereinafter specified. 1

The staple-driver 19 derives motion independently of the member 15 from the bar 17 as by impingement of a stud 48 extending from said bar against an arm 20 projecting from the top of the member 19 into a recess 21 provided for it within the case 13, the member 19 being preferably projected toward the stud by an expansive spring 23 interposed between the arm 20 and the en 22 of the recess.

The pendent link 49, above referred to, is of a length to admit of the dropping of its free end 50, under action of its own wei 'ht, into position above the staple-bender 15 zs'ee Fig. 8) when the bar 17 reaches its outward limit of motion. When the said bar hasmade sufiicient advance toward the member 3 to effect engagement between the snubnose 5O of the link 49 and the rounded shoulder 84 that is disposed on the case 13 in the path of movement of said nose, the link will be, by said shoulder, brushed aside upon its pivot from engagement with the staple-bender 15, and the spring 18 will be substituted, with its yielding resistance to contribute a final resser-foot action, in place of the rigid link. The relative operations of the members 15 and 19 which have been described in the last paragraph result in two distinct movements, to-wit, first that of the members 15 and 19 conjointly, and then that of the latter independently of the former, with the objects in view of severing a section of wire 28 that is, by means hereafter to be specified, kept supplied to the Opposite feathmachine, shaping said section of wire into distinguished by its adaptation to provision made for its positive and true reciprocatory movement specially timed with respect to those members wherewith it coacts. For that purpose the member 25 is preferably mounted slidingly in a groove 24: through the open end of which projects, upon its limit of outthrust, the shaper 31, to a point at which the end thereof and the front of the staple-bender 15 are substantially flush each with the other. From that point at which it is preferably held normally by a spring 26, the member 25 is designed and adapted to make retreat at the proper time within the groove 24 sufiiciently to clear the way to the travel of the driver 19 toward the anvil 44.

As a means for actuating the member 25 against the force of its spring 26, we prefer to employ an arm 25 which is adapted to accept motion from a stud 4O projecting from the bar 17 and communicate it to the member 25. To that end the arm 25 may be provided with an oblique face 25 against which the stud L0 strikes with each movement of the bar 17 toward the supporting member 3, forcing the arm 25 aside with a wedge action, it being obvious that in this instance the transposition of the inclined plane of the ordinary wedge from-one cooperating member to the other in no wise materially alters their combined action. In other words the operation of a true wedge upon the end of the stud 40 against a displaceable arm 25 would be identical in result and principle with the mechanism referred to in the last sentence. To reduce friction, the end of the stud 40 carries, by

preference, the roller 41 for engagement with the face 25*.

In the foregoing specification it was deemed conducive to clearness to omit special reference to the buttons with which the machine, in service, constantly has to do. It

' is now pointed out that each time the machine makes complete operation it is to ac complish, practically, the setting and securing in place of a button. The means of button supply to the machine and of utilizing the same which our invention affords, are important, both by reason of their structural directness and simplicity, as well as of their certainty and positiveness of operation.

The buttons may be fed from a hopper, supported upon the member 3 as by an arm 69, into a chute 79, but our invention, so far as relates to this application, includes, of those elements, only the chute, which being provided with a slit 80, extending from end to end of it, and enlarged as indicated at 87, wherethrough the button shanks of buttons fed and confined within the chute may pass, terminates in spring jaws 88 which yieldingly close the lower end of the chute against discharge of buttons therefrom. Buttons within the chute may descend by gravity alone with entire freedom of movement to the bottom of the chute defined by its jaws 88. Consequently a plurality of chutes with accommodation for buttons of different sizes may be used on our machine with complete interchangeability. The chute is secured to the casing by means of the bars 82, fixed in the side plates 83.

By our invention the buttons are supplied without the aid of any intermediate feed mechanism directly to the staple-shaper from the chute, and are thence withdrawn by the first movement of the staple-bender 15 that succeeds the retreat of the stapleshaper 31 before the driver 19. The directness of the operation referred to in the last sentence is accomplished by providing a slit 33 in the face plate 32 of the case 13, so that when the chute 79 and the face plate are operatively juxtaposed, as they are when the chute is set into its sheath 81, the slits 33 and 80 are brought together and made to register with each other and with the groove 19 in the face of the driver 19. Consequently, whenever a button loaded chute is supplied to the machine the shank of the lowermost button, or the one next to the jaws 88, projecting through the slit 80 of the chute, enters, without any opposition, the slit 33 and directly above the groove 26 on the shaper 31 and there into place to receive a section of staple wire 28, which may be supplied from a reel 30 as through a guide piece 29.

If now, for the moment, it be assumed that with the completion of each outward move ment of the bar 17 a feed of the wire 28 is made through the apertured guide piece 29 until the end of the wire abuts against the wall of the case 13 that is opposite the piece 29, it will be readily understood that the successive operations of severing the wire into a staples length, bending the severed section, and driving and clenching it will follow in regular order upon operation of the mechanism previously specified. It should be observed that the wire is conveniently and therefore preferably cut by the shearwise movement of the bender 15 within and against its case 13.

lVith each wire feeding operation a section of wire is, in practice, passed through the shank of a button presented to it within the chute 79 itself and above the shaper 31, so that the severed wire section becomes an operative element of the mechanism, and the sole operative means for withdrawing the button from the chute against the yielding resistance of its jaws 8-8. It becomes therefore of peculiar importance that the wire section should be each time supplied to and fitted within the machine with mechanical accuracy, not only because such accuracy contributes to the proper shaping and dis position of the staple within the grooves 47, but also because upon it depends perfect eertainty of operation in the advance of each button from the time of its delivery to the machine to that of its final discharge therefrom.

Therefore, while our machine, to the extent specified hitherto will operate as suc cessfully, perhaps, as machines heretofore known in the art, yet to insure practically perfect certainty of operation and that degree of accuracy required only by the highest standard, we provide in addition to the previously described means of direct delivery of button shanks to the groove 26 of the shaper 31, a button holder 36 which, carried, as it is preferably upon a sliding bar 35, and working through the enlarged slot 87 in the end of the chute 79, is, by reason of its shape and disposition, adapted to firmly and positively hold each successive button not only firmly against the end of the shaper 31 and the adjacent face of the face plate 32 whose lower end is channeled to a feather edge to meet the shaper, but also with an upward tilting motion whereby the shank of each button as it is presented is positively set into a definite location against the plate 32, its shank confined within the slit 33 and the end of the groove 26*, whereby possibility of deflection of the wire 28, as through inaccurate presentation of a but ton shank, which might otherwise occur as through wear in long use, is avoided.

Moreover, by our invention a button once caught between the holder 36 and the shaper 31 is held immovably between them until the staple is fully formed with its legs accurately confined within the grooves 47 ready for the final setting operation of the driver 19. It is then and then only that the simultaneous retreat of the shaper 31 and movement of the holder 36 operate to release the stapled button and permit the staple thereof to descend the grooves 47 under impingement of the driver 19.

The simultaneous operation of the shaper 31 and of the button holder 36 is accomplished by providing upon the sliding bar 35 an arm 37 that is similar to the adjacent arm 25, to which it is disposed in operative relationship in respect to its having a beveled face 38 corresponding in function to the face 25 of the arm 25. A spring 39 yieldingly holds the bar 35 in that position in which its button holder 36 tends to engage a button, while actuation of said bar is effected by engagement of a. roller 42 on the stud 40 with the face 38 of the arm 37. In the preferred construction of our machine the stud 40, through the simultaneous engagement of its rollers 41 and 42 with the faces 25 and 38, as above described, becomes a common actuating member for the two members 25 and 35. v

By reason of the relationship of the staple-shaper 31 to the staple-bender, and its disposition upon the end of the bar 25 so as to constitute a part of the longitudinal extent thereof, as well as the open endeddisposition of the groove 24 within which, preferably, the bar 25 works with close fitment, we are enabled to provide adequate and convenient means of keeping the working parts clear of obstruction. For example, if by careless operation of the pedal lever 12, or in any wise, two staples or a piece or pieces of wire be caught in or between any of the working parts of the machine proper, the operator may, by the pressure of finger or thumb on the arm 25, retract the bar 25 into its groove 24 against the spring 26 until the ends of the groove and of the member 31 are brought flush with each other. The effect will be to strip the member 31, through itsv sliding action within the groove, of any obstruction that may ride upon it. Quick release of the arm 25 will effect return of the bar to its normal limit with a snap action which will not only of itself tend to clear the member 31, but will also drive out any obstruction that may offer resistance ahead of its movement.

It was assumed, for convenience, at one place in the foregoing specification that wire 28 is fed from a reel 30 at required intervals to the guide. piece 29. Mechanism for the performance of that function is shown in Fig. 8, to which attention is now directed.

At the rear side of case 13 is secured an arm 51, upon the free end of which, upon the pin 53, is mounted a feeder arm 52. To the lower end of the arm 52 is pivoted, at 54, a jaw 55 which is normally held closed, as by .a spring 56, against a coacting jaw 57. These jaws preferably have considerable horizontal lengthand so tend by their bite upon the wire 28 to securely hold the wire, and thereby and by pull upon the wire against its keeper to straighten any kinks that may exist in the wire before it enters the guide piece 29. On the inner face of arm 52 is carried a bar 59 which has a slot 60 to receive a pin 61, by which the bar 59 is slidablysecured to the arm 52. This bar is connected at its lower end with the jaw 55 and extends toward the upper end of arm 52. Upon a pin 62 is pivoted a dog 63 which, engaging the upper end of bar 59, carries at its free end a roller 64.

To the bar 17 is fixed a cam arm 65 disposed in line with roller 64, so that when the bar 17 is driven toward the part 3 the cam arm will, by engagement with the roller 64. actuate the bar 59, through the movement of the dog 63, and open the jaw 55. At this point the cam arm 65 will, ineits further movement, engage a roller 66 mounted on a projection 67 on the adj acent side of the arm 52, and actuate the latter against the tension of a spring 68 which normally attracts it toward the case 18. The return of arm 17 to its normal position, as under expansion of the spring 7, releasing the arm 65 and allowing the jaws 55 and 57 to close upon. and grip the wire, permits the tension of the spring 68 to force the wire unwound from the reel 30 through the guide piece 29 and the shank of the button on the shaper as and for the pur pose already described.

The operation of our machine has been referred to throughout the body of the fore going specification, but may perhaps to advantage be briefly sumarized in the followmg. a

In operation the foot lever 12 will be depressed, thereby operating the rod 10, its head 5, and actuating bar 17 which carries the stud 4:0 and link 19.

Thereupon, the link 4:9 engaging the upper end of the member 15, which drives it against the wire 28, after severing it, bends over the staple-shaper 31 the severed wire section into a staple whose legs enter the grooves 47. At this point the snub nose 50 of the link 49 will engage the rounded shoulder 84- at the upper end of the case 13, there by disengaging the link and allowing the bar 17 to continue its movement against the yielding resistance of the spring 18. Here the rollers 11 and 42 will simultaneously engage the faces 25 and 38, respectively, forcing the button holder 36 against the tension of its spring 89, and the staple-shaper 31 against the tension of its spring 26, with the ultimate effect of releasing the button and removing the shaper 31 out of the way of the driver 19. The stud 48 will at the proper point in the movement, by contact with the arm 20 of the driver 19, force it upon the staple held in the grooves 17 with the result of passing the legs of the staple through the object 85, to which the button is designed to be attached, each leg being presented against its respective face 16 of the anvil 44;. The

. final result of the movement of the driver is to clench the staple into place.

The same downward stroke of bar 17 will carry the cam arm 65 against the roller 64:, depressing the dog 63 against the bar 59 to open the jaw 55, when, upon engagement between the arm 65 and the roller 66, the position of the arm 52, with respect to thewire 28, will be shifted.

Upon releasing the foot lever 12 the bar 17 will be forced to its outer limit by the spring 7, thus allowing the staple-shaper 31 to return to position in front of the driver, which, upon release, is restored to its starting position, and the button holder to be drawn rearwardly by the spring 39, which will carry the recurved and forked terminal 36 through the slot 87 of the button chute,

where the forked portion will engage and properly situate, to receive its wire, the lowermost button of the chute.

The cam arm 65, being retracted by return movement of the actuating bar 17 and the bar 59 thereby released, permitting the jaw 55 to bite against the jaw 57 upon the wire 28, the tension of spring 68 will actuate the arm 52, which in one movement by aid of its jaws 55 and 57 draws out the wire 28, and thrusts the end thereof through the guide piece 29 and the eye of the button against the opposite side of the case 13, ready for repetition of the operation as above described. Thus it will appear that each forward movement of the actuating bar 17 is calculated to set a button in position, and the return movement thereof to present another button for the machine to set.
