To all whom it may concern Be it known that I, iLnnn'r J. BEALIER, a citizen of the United States of America, residing at- Portland,-in the county ot Multnomah, in the State of Oregon. have invented certain new and useful Button-Attaching lltlachines ot which the following is a specification, reference being had to the accompanying: drawings.
My invention relates to machines for attaching buttons as to shoes or other objects ready for use, and belongs to that type oi machine in which a button is supplied, by each operation oi the machine, with wire, which having been, by the operation of the machine, severed to form a staples length and shaped in respect to such length into a staple, is, in the final operation of the machine, driven through the material composing the shoe or other object, and securely clenched thereto. In my machine, as in others of the same type, each cycle of its operation is designed to set a button, and to make preparation for setting another in uninterrupted succession.
From among" the numerous objects of my invention relating particularly to simplicity and durability of construction, cheapncss of manufacture, and, economy, certainty, and efiiciency of operation, I mention the button attaching mechanism proper, both in respect to its various members, their relationship one to another, and their actuating mechanism. also the wire 'ccding mechanism, its operative relationship to the machine as a whole, and the wire straightening mechanism.
In respect to those as well as to other objects of my invention, it is noted that what constitutes my invention will be hereinafter specified in detail and succinctly set forth in the appended claims.
In the accompanying drawings,
Figure I is a perspective view looking; toward the front oi my machine as at rest and complete save only in respect to the foot or other power'ior operating it. v-rhich is only indicated in certain preferred details.
Fig. II is a top plan of a portion of the subject matter of Fig. I th. p: ts being shown in full lines in the positions they oca chute engaging snag bolt.

Fig. X is a similar view of the staple shaper.
Fig. XI is view similar to Fig; VII. showing position of the parts upon final movement of the main operating lever.
Fig. XII is a view similar to Fig". XI. illustrating a portion of the frame shown therein stripped of the movable parts which, in assemblage, it contains.
Fig. XIII is a det: 'l SQClJlOjD on line XIII-XIII of Fig. II, with parts omitted.
Fig. XIV is a detail edge view oi the lower end of the wire feed arm and wire grip thereon, detached.
Referring to the numerals on the drawings 1 indicates the main assembling memberor supporting frame of my machine. In its present preferred for 1 shown, it surmounts a tubular standard 2, and comprises a housing 8 adapted to accommodate within it a main operatinp member l that is preterably a lever pivotal'ly mounted upon a transverse pin 5 in th opposite walls of the housing. 3. A simple, and for that reason, preferred means of impartingoscillatory motion to the lever l upon its pivot 5 compri a head 6, pivoted, indicated at '7, to the said lever, whose preferred contour clearly for instance.
shown in Fig. V, and affixed to the upper end of a rod 8 that is incased within the standard 2. A spring 9, seated at one end against the head 6 and, at the other, against supporting pins 10 transversely disposed within the standard 2, serves to yieldingly uplift the rod 8 and to urge the lever 4, upwardly (compare Figs. I and V).
The housing 3 is preferably flanked with side walls having faces 11 and 12 disposed in the same inclined plane, and is, by a floor 13 inserted between said walls parallel to their said faces, provided with an open ended case 13 whose fourth side is supplied by a face-pl ate 14 removably secured against the faces 11 and 12 as by screws 15. The floor 13 is slotted longitudinally, as indi cated at 16 to accommodate the movement of the neb 17 of the lever 4. v
The case 13, surmounted by the face-plate 14, is shaped in transverse internal contour (see Fig. XIII) to accommodate a preferably reciprocatory driving block 20 preferably quadran ular in cross section, as illus trated in various figures, but particularly Fig. VI, and provided with a fin 21, which, depending through the slot 16 in the floor 13" of said case, brings the block 20 into operative relationship with the-lever 4, to which it is operatively united as by a link The link is preferably a plate, to accommodate which the lever 4 is bifurcated or slitted as indicated at 23 in Fig. VI, and the fin 21 is kerfed as shown at 24 in Fig. V, Pivot pins '25 and 26 unite the link 22 to the block 20 and lever 4, respectively.
The end of the case 13 below that occupied by the block is designed and adapt-ed for the accommodation of a staple-bender, 30, and a staple-driver, 31, which are, preferably, for the most part, of construction I known in the art, and which cooperate with a staple-shaper, 32, preferably, also, of familiar type.
As known in the art the staple-bender is bifurcated and provided in its opposite legs with the usual staple grooves 33 communieating, respectively, with terminal staple grooves 34. 'The staple-driver 31 fits between the legs of the staple-bender and, feathered to the grooves 33 thereof as by feathers 35, is provided with the usual button shank channel 36, and driving face 37.
The members and 31 are distinguished, respectively from what is old in the art by a terminal bearing chamber 40, in the former, and by a shank 41 on the latter, fitting the chamber and removably secured to the member 31 as by a screw thread connection 42. The member 31 is also provided with a forwardly inclined face 43 of novel functional significance, as will hereinafter apear. p The relative assemblage of the members 20, 30, and 31 within their case is well shown in Fig. II wherein the View is made with the face-plate 14 of the. said case removed. A comparison therewith of Fig. V, for example will serve to explain the details of their relationship, which I proceed to describe. The block 20 is provided with a chamber 44 that is coaxial with the chamber 40 and with the shank 41 within it, and whose diameter will admit the kerfed shank head 45.
A spring 46 preferably coiled about the shank 41 and seated within the chamber 40 against a constricted throat 47 therein projects from the member 30 toward the block 20, with the ultimate effect, consequent upon a sufficient advance of the block, of interposing a cushion connection between the members 20 and 30.
The chamber 44 extends from its throat 48 outwardly through the block 20 and is internally threaded to receive a screw plug 50 whose adjustment of set within the chamber is adapted to be fixed by a jam nut 51.
The staple-shaper 32, with which, as specified above, the staple-bender and stapledriver cooperate, is preferably mounted slidably ina barrel provided for it in the frame 1 as clearly shown in V, and is provided with a cam faced arm 56 pro jecting through a slot 57 in the barrel 55, its cam face being indicated by the numeral 58. A stop pin 60 is provided in the barrel 55 to close the open end of the slot 57 against the escape therefrom of the arm 56, while a spring 61 seated in the bottom of the barrel 55 yieldingly projects the shaper 32 in the direction of the pin 60. The shaper is retracted by direct engagement with it of the lever 4, as by means of a roller 62 on a pin 63 working against the cam face 58.
A button holder 64, pivoted preferably to the outside of the case 3 as indicated at 65, is provided with an arm 66 which, terminating in a button-engaging jaw 67, cooperates with the shaper 32, under tension of a spring 68. to hold a button fixedly in position upon the grooved terminal 69 which characterizes the shaper 32. The holder 64 is preferably provided with a compound cam face against which a stud pin 70, projecting from the side of the lever 4 through a slot 71 curved to accommodate the movement of that lever about its axis 5, makes engagement to actuate the holder. The pin preferably carries an antifriction roller. The cam face preferably comprises two projections 72 and 73 the former serving to hold the jaw 67 normally separated from the end of the shaper 32, and the latter, to separate it therefrom toward the end of each complete oscillation of the lever 4, for reasons hereinafter explained.
The presence of a recess 75 dividing the projections 72 and 7 8 permits, in operation, the jaw 67, under tension of its spring 68, to engage and hold momentarily a button in determined position upon the shaper terminal 69. I do not claim as my invention the button holder broadly, but only in respect to specific details thereof, except in respect to means for controlling its button holding function whereby a button is held or released by the jaw 67 for the purpose hereinafter specified.
A horn 77 upon the frame 1 presents an anvil 78 or staple-clencher in operative relationship to the staple-bender and stapledriver for the final operation of the machine in setting and clenching a staple, as is well understood in the art and as illustrated in Fig. XI of the drawings.
A projecting support 80, fixed to the case 13, affords at 81 a pivotal support for a wire feed arm 82, whose function it is to feed, at intervals, wire 83, as from a reel 84, between the staple-bender and stapleshaper as shown in Fig. II, through an aperture 85 provided for its admission in the next adjacent side wall of the case 13. The reel 84 is preferably carried upon an arm 86 that is supported by an upright 87 upon the frame 1. The wire 83 as it uncoils from the reel 84: is objectionally bent by reason of its having been wound upon the reel 84, and my invention includes wire straightening mechanism whose preferred a form of embodiment will clearly appear from a comparison of Figs. II and III. Referring to those figures, 90, 91 and 92 indicate, respectively, three screws employed to fasten the arm 86 to the upright 87, their number and triangular disposition shown being selected to accommodate them to the performance of the wire straightening function. To that end, each screw is shouldered as indicated, for example, at 93 to engage the arm 86 and is headed as inclicated at 94 to revolubly confine upon the shoulder a roller 95. Each roller has an annular groove 96. In practice the wire 83 passes between the rollers of the lateral screws 90, 92 and the intermediate 91, whose respective grooves 96 are alined to engage and hold it. By making the necessary rela tive disposition of the rollers and providing means to compel contact of the wire 83 with the intermediate in passing between the laterals 90 and 92. the wire may be set in a straight line. I prefer to employ a bellcrank dog 98 pivoted as indicated at 99 to the arm 86 between the lateral screws 90 and 92. The nose of the dog is made yieldingly to press and to hold the wire against the roller of the intermediate screw 91 through tension of a spring 100 fastened at one end to the arm 86 and at the other to the tail of the dog thereby performing the familiar function of holding the wire against the backward movement of the arm 82, which in its forward movement feeds the wire 83 through the aperture 85. To this end the arm carries at its free end a headed stud 101 and a coacting dog 102 and its spring 103, corresponding to the dog and spring, 98-100. The dog 102 yields with the backward movement of the arm 82 to slip upon the wire and with the reverse movement of the arm to grip upon and pay out the wire, while the dog 98 yields to a pull upon the wire exerted by the arm 82 but resists movement of the wire in the opposite direction.
I prefer to employ for actuating the arm 82 means which will cause it to take hold of the wire 83 with each of the lever t, and also, by preference, which will interrupt the feed of the wire until it is required to supply a button about to be attached in place by my machine. In this way, not only is a positive driving force employed advantageously to take the wire as contradistinguished from thespring power usually employed hitherto, but also the waste of wire is avoided and an advantage is gained for the removal of that type of button chute which I prefer to employ. To the end in view as set forth in this paragraph, I prefer to provide upon the block 20 a plate 105 which extends laterally therefrom through a recess 106 provided for it in a side wall of the case 13 which is also provided with a deeper recess 107, as clearly shown in Fig. XII. The plate 105 terminates in a beveled faced arm-actuating-memher 108 which with each forward reciprocation of the block 20 operates like a wedge against a roller covered the arm 82 in the path member 108.
The arm 82 is urged to swing upon its pivot toward the case 13 as by a spring 110 fastened at one end as by a pin 111 to said case and adjustably secured at the other end, as by a knurled thumb nut 112 upon a threaded terminal 113 secured to said spring and passed through an aperture 11 1 provided. for it in a stud 115 on the arm 82.
The above described movement of the arm 82 under tension of its spring 110 is normally prevented while the machine is at rest as by a spring-actuated dog 116 pivoted at one end within the recess 107 as indicated at 117 in juxtaposition to the end wall 118 of said recess whereby the power of its spring 120 is resisted by it, as a stop piece, so as to cause the dog 116 normally to maintain the position at right angles to the wall of the case 13 and, as shown in full lines in Fig. II, opposite to the stud 109. In order to cause the member 108 to displace the dog 116 in each forward movement, I provide a pushpiece 121 pivoted as upon a screw 122 to the stud 109 carried by of movement of the positive operation a member 108 near its forward end, and impelled toward the case 13 as by a weak leaf spring 123 fastened edgewise to the memher 108. The push-piece is preferably beveled as indicated at 125 on its edge next the faceplate 14 against which it rides, and it is provided upon its free end with a projection 126 that impinges against a rounded stud pin 127 on the dog 116. Consequently, initial forward movement of the block 20, by aid of the push-piece, drives the dog 116 out of the way of the stud 109, with the effect of feedin" a staples length of wire through the aperture 85 before the block 20 actuates the staple-bender 30 which is also the wire cutter. As soon as the dog 116 releases the stud 109, the arm 82, without waiting for the completion of movement of the push-piece 121, brushes aside the dog by the power of its spring 110, and so accomplishes its wire feed function at the right moment. Upon return movement of the block 20 that carries with it the push-piece 121, the spring 123 permits the projection 126 to slip around the pin 127 without disturbing the position of the dog 116.
The button chute 130 which I prefer to employ for delivering buttons to my machine requires no detail description herein since I lay no claim to being the inventor of it. It is of a type recently produced and is detachably secured to the faceplate 14 as by pockets 131 in a base-plate 132, engaging stud buttons 133 on the face-plate 14. My only invention in respect to the chute is shown in Fig. IV and comprises a snap bolt 135 working in a recess provided for it in the case 13. Theend of the snap bolt, actuated by a spring 136, entering an aperture provided for it in front of the base-plate 132, acts as a keeper to fasten the chute to the face-plate 14. It is conveniently released by manipulation of a pin 137 projecting from the bolt 135 through a slot 138 in the case.
To render the operation of my machine intelligible to one skilled in the art, the following is deemed suflicient. Power supplied by any suitable means, not illustrated, properly to actuate the rod 8 against the power of its spring 9, will effect operation of the lever 4 upon whose movement the operation of the entire machine depends. The position of the parts of the machine when at rest is shown in Fig. V. From the initial position it occupies as shown in that figure, movement of the lever 4 is communicated to the block 20, causing it to travel in its case 13 to cause the inner end of the plug 50 to encounter the head 45 of the staple-driver shank 41, this point being determinable by adjustment of the plug 50 in its chamber 44. The block 20 should meet the spring 46 before the plug 50 encounters the shank head 45 (see Fig. VII for example). At
about the same moment the neb 17 engages the end of the staple-bender 30 that is next the block 20, advancing it with ample force to cut a staples length of wire in the usual manner common to this type of machine. The drive of the staple-bender by engagement with it of the neb 17 continues substantially till the staple is bent over the shaper terminal 69, when the spring 46 supplants the neb 17 as a driver of the member 30, imparting to it a yielding or presserfoot action that is familiar in the sewing machine presser-foot. The lever 4 is the main operating member of the machine, as specified. Its neb 17 constitutes an actual immediate means, as denominated in certain of the claims, of connection between it and the staple bender 30, while the block 20, operatively connected to the lever 4, as by the link 22, constitutes a means of mediate connection between said lever and staple bender. The spring 46 renders said means of mediate connection a yielding means during a part of the forward travel of the block 20.
Upon the bending of the staples length of wire over the shaper terminal 69 to shape a staple. the shaper is withdrawn from between the legs of the bender 30 through engagement of the roller 62 on the lever 4 with the cam-face 58 of the arm 56, assisted, if need be, by the wedge action of the inclined face 43 of the member 31 against the shaper terminal 69. At about the moment that the shaper 32 is completely retracted the swing of the lever 4 upon its pivot 5 is advanced to such a point as to bring the plug 50 into contact with the shank head 45. The continued stroke of the lever 4 thereafter advances the block 20 to the limit of its forward movement within its case, as shown in Fig. XI, thereby through the interposition of the spring 46, driving the staple-bender 30 toward the anvil 78 with presser-foot effect against the material indicated by the numeral 140 to be supplied with a button. At the same time the plug 50 through said contact with the shank head 45 of the staple-driver 31 drives home the staple and clenches it into the material 140. coincidentally with the operation of the block 20 described, the dog 1.16 in the manner heretofore explained and at the right moment is by the push-piece 121 driven out of the way of the arm 82 with the result that the lowermost button in the chute 130 is, with each forward stroke of the block 20, supplied with wire just in advance of the initial movement of the member 30 which severs a staples length of wire substantially at the precise moment it is required by the staple forming mechanism comprising as it does the staple-bender, and shaper.
Also the button holder 64 whose jaw 67 is held in inoperative position by engagement of the cam projection 72 with the stud pin 70 is, through the forward stroke of the lever 4: which carries the stud pin, brought into requisition to grip the aforesaid lowermost button in the chute 130 and to hold it in a oeterminate relationship to the staple-shaper 32 as well as to the aperture 85 until the button shank takes its staples length of the wire 83 and the said length is caught and secured between the staple-bender 30 and the shaper 32. Thereupon, engagement between the stud pin 70 and the cam projection 73 releases the button which is now, so far as required, held by its staple. After the stapled button has been discharged from the chute 130 the button next in order therein takes its place in the chute, but it is not engaged by the wire 83 until it is caught in the button attach ing operation of the machine. In consequence thereof as well as of its disengagement from the jaw 67 of the holder 64, as pointed out at the commencement of this paragraph, the chute 130 may be removed, as for supply of difierent sized buttons, whenever the machine is at rest, both conveniently and without any waste of staple wire. This is regarded as an important ad vance in the art particularly so far as relates to that preferred type of button chute wherein the button is presented to the staple-shaper directly within the chute itself.
The return stroke of the lever at and with it the block 20, by restoration of its parts to position shown in Fig. VII, prepares the machine for a repetition of the button attaching operation described.
