` Application led March 27, 1903.

T0 all L11/1,0m it may concern:A

Be it known that we, HORACE L. VEDGE and WILLIAM EDGE, residents of New York city, borough of Brooklyn, New York, have invented certain new and useful Improvements in Staple-Making Machines, of which the following is a specification.

The object of our invention is to provide a machine for making staples from continuous lengths of wire fed thereto, and particularly staples having conical or tapering points; and to these ends we provide means for feeding Wire and cutting it into desired lengths, means for'holding such lengths of wire while their ends 'are being pointed, and means for bending the pointed lengths of wire into staple form andA discharging the staples from the formers. The invention further contemplates the novel features of improvement hereinafter more fully set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a plan view of a machine embodying'our invention. Fig. 1a is a detail section on the line 1fL of Fig. 1. Fig. 2is a side elevation of the machine, partly broken.

Fig. 15 is a detail section on the line 15 15 in Fig. 1 looking in the direction of the arrows. Fig. 16 is an enlarged detail view of one of the staple-pointing cutter-heads, and Fig. 17 is a section thereof on the line 17 17 in Fig. 16.

Similar characters of reference indicate corresponding parts in the several views. i The numeral 1 in the drawings'indicates a frame, which may be of suitable construction, and at 2`is` indicated a shaft journaled in suityable bearings on said frame and shown provided with a driving-pulley 3, and in the arrangement shown pulley 3, while mounted freely upon shaft 2, is adapted to be clutched thereto by suitable clutching mechanism, (indicated generally at 11,) although a fast and loose pulley of usual form can be used for operating shaft 2. Shaft 2 is also provided with pulleys 5 6 for operating the staple-pointeur.- ters, as hereinafter set forth.. At 7 is indicated a shaft carried in suitable bearings upon frame 1, and said shaft is illustrated as adapted to be operated from shaft 2 by interposed gearing, as 8 9 10 11, for giving shaft 7 the desired speed and direction of rotation.

The wire (indicated at 12) from which the staples are to be formed and which may be carried to the machine from a reel and passed throughV suitable or well-known wire-.straighteners is presented to intermittently-rotative carrier or disk 13, that is provided with grippers to hold lengths of wire while the ends thereof are being pointed and the pointed lengths bent into staple form. The carrier 13 is mounted upon a stud 14, carried by a standard or the like 15, supported by frame 1, Fig. 9. The means shown for intermittently rotating carrier 13 comprise a ratchet-wheel ciprocate the member 20, the same is shown provided with a slotted head portion 20 to receive and be guided by shaft 7, and said head is shown provided with lugs 20" 20, adapted to be engaged by a pin 21, carried by shaft 7, as upon a fiange or extension 22 secured thereto. Said pin and lugs reciprocate member 20 and allow a rest between each stroke. The means shown, however, for intermittentl y rotating carrier 13 may be varied from that set forth, if desired.

To lock carrier 13 in position to receive lengths of wire and while a length of wire is being pointed, we have shown a locking-pin 23, adapted to enter apertures 13 in the car-l rier and arranged and operated as follows: Said pin is supported in suitable bearings carried by frame 1 (see Figs. 12 and 13) and operated bya bell-cranklever 24, adapted to engage lugs or pins 23 on the pin 23, the lever being suitably pivoted, as at 25. From the bell-crank 24 extends a rod 26, that is connected with an arm 27, pivotally carried by frame 1, as at 28. To arm 27 is pivotally connected a rod 29, (guided in suitable bearings, as 30, carried by frame 1,) which carries a finger 31, adapted to be engaged by a cam 32, secured to shaft 7; (See Fig. 14.) The cani 32 has a portion 32 to engage and push finger 31 to the right in Fig. 14 to positively operate bell-crank 24 to push pin 23 into an aperture 13 in carrier 13, and said cam has a surface 32 to ride against finger 31 and hold the pin 23 in thelast-named position for a certain length of time, (while a staple length is being pointed,) the finger 31 being free after the part 32c of cam 32 passes therefrom. Then the last-named action occurs, a spring 33, connected with the pin or another part of the device, serves to withdraw the pin and restores the connected parts to the idle position. The parts above described provide convenient means for operating, locking, and releasing the carrier 1 r The wire 12 is fed to grippers on the carrier or disk and cut into 1engths,and such lengths are held by the grippers and carried to the devices for pointing the ends,and means are provided for bending the pointed lengths into staple form and disengaging the completed staples, and in this connection we have shown three sets of gripping devices on carrier 13. As the clamping devices upon carrier or disk 13 are all similar, a description of one will sufiice. A movable gripping member is indicated at 35 pivoted upon carrier 13, as at 36, and provided with a finger 37, projecting beyond the periphery of the carrier in position to engage a cam 38, carried by frame 1, whereby as carrier 13 rotates in the direction of the arrow 6 in Fig. 3 the finger 37 will engage cam 38 to open the gripper, as indicated in Fig. 4, and when finger 37 passes from said cam the gripper will close. In Fig. 6 is indicated a plunger 39, bearing against gripper 35 and pushed byaspring 4() to normally hold the gripper closed. The gripper shown is in the form of an arm of suitable dimensions cut through or forked at its free end at 35 and provided with a groove 35", that leads to the space between the forks 35C. r1`he free end of the gripper (or its forks 35C) is provided with a recess 35, adapted when the gripper is closed to aline with a corresponding recess 35, formed in or carried by carrier 13, whereby is provided a socket 35, Fig. 6, to receive a length of wire 12, from which the staple is to be formed, the gripper normally holding the wire in such socket. A (See Fig. 3.) For convenience of manufacture we provide a block 41 for each gripper, which is secured in a corresponding recess 42 in the carrier 13, and said block may be made in two parts secured together by screws 43, screws 43 holding the block on disk 13. (See Fig. 9.) At the part of block 41 contiguous to recess 35e is a groove 41, that alines with the space 35 between the forks 35c of the gripper, Figs. 5 and 6,where by when the gripper is closed the grooves 35", 35, and 41form a continuous groove to receive a staple-bending finger 43. The surface of carrier 13 between the blocks 41 is also grooved, as at 13", (see Figs. 1 and 9,) in line with the grooves 35", 35, and 4l, whereby a continuous groove is provided around the periphery of carrier 13 to receive the finger 43. (See Fig. 10.)

The wire for the staples is fed to and through the sockets 35f of carrier 13 while gripper 35 is closed, so as to project from opposite sides thereof, and is then cut off intermittently to produce lengths of wire for the staples. To this end the wire 12 is fed through a stapleguide 48, carried by frame 1, and the relation of the parts is such that when pin 23 locks disk 13 in the stationary position a socket 35f will be alined with the guide 48 to receive wire therefrom. To cut off the wire into the desired lengths, a knife or cutter 49 is provided (see Figs. I and 3) adapted to coact with the edge of guide 48, which knife is secured to an oscillatory shaft 50, mounted in suitable bearings on frame 1, and in the eX- ample shown said knife is operated by the reciprocative member 20. To this end an arm 51 extends from shaft 50I into position to be engaged by an extension or pin 52, carried by member 20, a spring 53 connecting arm 51 with a stationary part, as frame 1 at 54. (See Fig. 3.) When member 20 moves to the right in Fig. 3, pin 52 and arm 51 move knife 49 upwardly to cut the wire 12, and as pin 52 passes from arm 51 spring 53 restores said arm and knife to the normal position. When pin 52 returns, it slides back behind arm 51. (See Fig. 4.) To provide for different lengths of wire to be projected from guide 48 for making staples of different size, said guide is made adjustable toward and from carrier 13, and to this end guide 48 is shown carried IOO by a slide 53, mounted upon frame 1 and provided with a clamp 54 to hold the guide in adjusted position,.which clamp may consist of a screw having a handle 55, the screw being threaded in the frame to lpass through a slot 56 in slide 53. As shown, the shaft 50 is journaled at one end in the body portion 48 of guide 48 and is adapted to slidein the bearing 1X, the shaft 50 being confined by knife 49 and a collar 57 in the bearing at 48, so that as the guide is adjusted towardL and from carrier 13 the knife 49 will be correspondingly adjusted, thevshaft sliding in bearing 1X.

Any suitable means may be provided for feeding wire 12 to the sockets 35f of carrier 13, and for such purpose the following arrangements are shown: Upon a web or guide 53 of member 53, Figs. 1 and 15, is mounted a slide 60, that carries a gripper 61, pivotally supported upon said slide at 62, the gripper 61 having an under gripping-surface at 61, adapted to clamp the wire upon slide 60. The gripper 61 is normally pressed toward the Wire 12 by-a spring 63 acting against the arm 61h. Vhen slide 60 moves toward guide 48, the gripper 61 acts upon the wire and pushes the same forwardly; but when the slide returns the arm 61 slides freely` over the wire. To hold the wire rigidly during the return stroke of slide 60, there is provided a stationary gripper corresponding to 61,which is illustrated more clearly lin Fig. 1, wherein the wire 12 rests upon a bed 63, and an arm 64, pivotally supported above the wire and provided with a gripping surface or teeth at 64, (the gripping-surface of 61 being similar,) bears upon the wire. The arm 64 is pivoted at 65 and held down upon the wire by a spring 66. rThe arrangement of the parts is such that Wire 12 may freely pass to the left in Fig. 1 when drawn by the gripper 61; but when gripper 61 slides reversely arm 64 will grip wire 12 and prevent it from being pushed back, whereby gripper 61 may` slide freely over the wire. rEhe means shown for reciprocating slide 60 are as follows: To frame 1 is pivotally connected a lever 68, as atv 69, which lever is pivotally connected with slide 60, as by a link 70, and to shaft 7 is secured a suitable cam 71, .adapted to act upon a pin or roller 72 on lever 68, Fig. 1. A spring 73,

' connected with slide 60 and with frame 1, acts against cam 71. At the proper time cam 71 rocks shaft 68 to push slide 60 forwardly, and when cam 71 passes from pin 72 the spring 7 3 draws slide back with a quick stroke, the feeding of the wire' being caused by the direct action of cam 71, so that positive lengths of wire are always fed.-

The means for sharpening or pointing the ends of lengths of wire carried by the grippers upon disk 13 are arranged. as follows: When the wire length 12 reaches the position shown at A in Fig. 3, the ends of the wire are brought in line with cutters, and to firmly grip the wire during the pointing operation there is provided a plunger 75, carried in bearings in a bracket 76, supported by frame 1 and normally pressed .by a spring 77 toward the grippers 35, yadjusting-screw 78 being provided to regulate the tension of the spring. rlhus when the gripper 35 slides under plunger 75 the latter will forcibly bear on the gripper to confine the length of wire 12 firmly in socket 35i. In line with the ends of the wire length 12 that project from opposite sides of disk'13 are rotative cutter-heads adapted to advance toward and Aretreat from the corresponding ends of the wire, and as the two cutter-heads are substantially alike a description of one will suiiice. At opposite sides of frame 1 are located ways or guides 80, on which slides 81 are mounted to reciprocate, and said slides carry bearings 82, in which are journaled the shafts of cutter-heads 83, which have pulleys 84 85, alined, respectively, with the pulleys 5 6. The cutter-heads are shown more fully in Figs. 16 and 17. Said cutter-heads are shown provided with a block 86, having an aXial bore 86 to receive the end of wire 12, and within said block is secured a cutter 87, shown as held in place by a clampblock and screw 88 89, whereby the cutter may be readily adjusted, the cutter not being shown in Fig. 16. The inner surface of block 86, to which the inner end of aperture 86 leads, is beveled or inclined from the outer end of the head or block inwardly at an angle to the plane of the staplewire 12, and thus at an angle to the aXis of the cutter-head, and the cutter 8 7 lies upon such surface 86, whereby the cutting edge 87 is located at an angle to the axis of the wire 12. (See Fig. 17 r1`he wire 12, entering the aperture 86, meets the edge 87 of the cutter, and thereby as the cutter rotates, the wire. being held stationary, a conical or outwardly tapering point is cut upon the end of the wire, the cutter feeding toward the stationaryl wire. For convenience of manufacture the block 86 is madev removable from the cutter-head 83, and a hardened insertion 86b is provided in which the aperture 86 is formed; but it is obvious that the aperture 86 and the insertion 86b could be formed directly in the cutterhead 83, if preferred. An oil-hole 83 in head 83 conducts oil to the cutter. By preference IOO IIO

the cutter-heads 83 are made to rotate in opposite directions, so as to take rotary strain from the wire 12, clamped upon disk 13, and for this purpose one belt (indicated at 90) may run direct from pulley 5 to pulley 84, and the belt A91 from pulley 6 t'o pulley 85 may be crossed, as indicated in dotted lines in Fig. 1. 1n such case the cutting edges 87 of the cutters 87 face in opposite directions, and thereby points are simultaneously formed upon the opposite ends of wire 12.

The means shown for moving the cutterheads `simultaneously toward and from the wire 12, carried by disk 13, are as follows:

Upon a shaft 92, jou rnaled in suitable bearings upon frame 1,is secured a rocker-arm or cranks 93, projecting fiom opposite sides of said shaft and connected by links 94 95, Fig. 10, with the slides 81, whereby as shaft 92 rocks said slides will be reciprocated. As a convenient means for rocking shaft 92 we have shown gears 96 97 connecting said shaft with a shaft 98, journaled in bearings on frame 1, (shown carried in a housing 99,) the shaft 98 having a pin 100 to coact with a cam 101 on shaft 7, Fig. 1, for rocking shaft 98. r1`hus as shaft 7 rotates the cam 101, through the devices described, will cause slides 81 to reciprocate.

As provision is made for supplying different lengths of wire to disk 13 for producing staples of different lengths, as before noted, provision is also made for adjusting the cutterheads 83 toward and from disk 13 to accommodate such varying lengths of wire, while the cutter-heads 83 reciprocate a definite distance. To this end upon each slide is pivotally supported an arm 103, having a pivot or fulcrum point 104 connected to slide 81, the lower ends of said arms being pivotally connected to the links 94 95, the upper ends of said arms being adjustable. To hold the arms 103 in adjusted positions, we have shown apertures 105 at suitable distances apart, Fig. 10, provided in members 106, rigidly connected with slides 81, adapted to receive spring-controlled pins 107, carried by arms 103. As illustrated in Fig. 10, if the arms 103 are moved outwardly, their lower ends finding a fulcrum at the connection with links 94 95, the slides 81 will be similarly adjusted away from the wire 12", and, likewise, if the arms 103 be adjusted inwardly the slides 81 and the cutterheads 83 will be moved toward the wire 12. In either event the links 94 95 remain in positive position with respect to shaft 92, and thereby equal feeding to and fro of the cutterheads with respect to wire 12u may always occur, notwithstanding the lateral adjustment of said 'cutter-heads with respect to said wire. The finger 43 for bending the pointed wire lengths is shown as movably supported by an arm 44, hung upon stud 14, so as to oscillate to permit the staple that is bent byineans of said linger, Fig. 7, to be ejected therefrom. W'hen the sharpened or pointed length of wire is brought by a gripper into contact with finger 43, the wire first causes the latter to move to the left in Fig. 3 (the arm 44 turning on its pivot 14) until said arm is brought in contact with and pushes back a plunger 45, carried in a bearing 46, suitably arranged on frame 1, said plunger being normally pressed forward by a spring 47, bearing against the plunger and against an abutment at said bearing. (See Fig. 3.) Said arm 44 comes to rest against said bearing, the spring 47 thus being placed under tension. rhen carrier 13 rotates suficiently far to cause staple 12b, Fig. 7, to be bent, the staple will aline with the groove 41'l of block 41 and will be free to slide in such groove, which is sufliciently wide to receive the staple, (see Fig. 9,) and thereupon finger 43 will be free and spring 47 will push plunger 45, thus moving linger 43 downwardly with a sudden thrust until it is arrested by a stop, as 43X, thereby discharging the staple from the finger and the carrier upon the incline 1.

The complete operation of the machine may be described as follows: Assume that the wirereceiving sockets 35IE are all empty and that carrier 13 is held in the position shown in Fig. 3 by the pin 23, the various parts all being in in their proper positions. The machine being started, wire will be fed into one socket and knife 49 will cut olf a length of Wire, the rotary cutters operating idly. Cam 32 and the connected devices next cause pin 23 to be withdrawn from carrier 13, (cam 101 causing the rotary cutters to be moved outwardly,) and carrier 13 is moved one step, bringing the length of wire 'in line with the rotary cutters, and the carrier is locked. The cutters 87 then move toward the ends of the wire held in line therewith, and the cutters operate to produce conical points on the wire, another length of wire being fed to a socket of disk 13, now held in line therewith, and cut by knife 49. The rotary cutters then recede from the pointed ends of the wire, and the carrier is rotated another step, the last cut wire length being brought in line with the cutters, the pointed wire carried below, and a new wire fed to the third socket on earrier13, the same operations of cutting off one wire length and of pointing the ends of the previously-cut wire occurring. The parts will now be in the potitions shown in Fig. 3. The lowermost pointed wire is now ready to beV bent into staple form, and during the next step of carrier 13 the pointed wire (indicated at a in Fig. 3) will be advanced into contact with linger 43, and linger 37 will engage cam 38 to open gripper 35, the motion of finger 43 being'arrested by bearing 46, as indicated in Fig. 4. As carrier 13 continues to advance the jaws of block 41 pass by or straddle linger 43. and thereby cause the staple to be bent, as indicated in Fig. 7, and as soon as the staple is properly bent, so that it may freely pass through groove 41, the plunger 45 (which was previously pushed back by arm 44) springs forward, causing finger 43 to eject the staple 12" from the groove 41a, and the staple drops upon the base or receptacle 1". During the continued motion of disk 13 to the resting-point finger 37 passes away from cam 38 and the gripper 35 closes, as indicated in Fig. 3. 1t will be understood that after the three grippers have been supplied with staple-wire lengths appropriate operations upon the three wire lengths take place for each step or one-third rotation of carrier 13-that is to say, wire is fed from guide 48 and cut off by the cutter 49. A length of wire at the upper part of carrier 13 is pointed, and the pointed Wire at IOO ing upon three staple-Wires in connection With carrier 13, it is obvious that more or less grippers and parts to coact-therewith may be provided and properly arranged` in 'connection with each other, if preferred, and that instead of feeding Wirefrom a roll to the grippers and then cutting the Wire into lengths previously-cut lengths of Wire could be fed to the grippers. It Will also be understood that the various details of' construction may be altered and modifications made in the machine Without departing from the spirit of our invention.
