To all whom it may concern: Be it known that I, ll/IERTON D. PHE AN, a citizen of the United States, residing at Boston, in the county of Suffolk and State'of Massachusetts, have invented an Improvement in Metallic- Fastening Machines, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts. i

This invention relates" to machines for inserting fasteners and more particularly to a machine for making such fasteners from a continuous wire or strip and for driving them as made.

My invention is particularly useful in connection with what is known-as a slugging machine employed in the manufacture of boots and shoes. I

My invention aims especially to improve such machines forthe purpose of increasing the speed and consequent output. as well'as for improving the quality of work produced. My invention will be best understood from a disclosure of one embodiment thereof shown in the accompanying drawings and selected for the purpose of illustrating said invention but without any intention of limiting my invention thereto.

In the drawings accompanying this description: Figure 1. illustrates in side elevation a machine made in accordance with the selected embodiment of my invention. Fig. is an elevation of the opposite side of said machine but upon an enlarged scale. Fig. 3, is a front elevation of the machine, Fig. 1. also upon an enlarged scale. Fig. l, is a diagrammatic detail illustrating the driver carrier and the cam for reciprocating the same; Fig. '3. an irregular horizontal section on the dotted line 5-5'Fig. 1. Fig. (i, a A

Fig. 10, a vertical sectional detail illustrating the wire feeding mechanism detached, the same being approxi- ,mately a section on the irregular dotted line '1010 Fig. 2. Fig. 11, a plan View uf the feeding pawl audits carrier Fig. 10. Fig. 12 a sectional detail on the dot ed line 12-42 Fig. 10. Fig. 13,- another'diagram-' matic or detail view, illustrating the awl driving and work feeding means detached, said view being in effect a front view with the driver and 'awl carriers broken away to show-the parts in the rear, and Fig. 1-1, a detail of parts shown in Fig. '13 to be referred to.

In the particular embodiment of my invention selected for illustration herein, and shown in the drawings referring first to Fig. 1, the machine is mounted upon any desired column 1, the same carrying the machine head 2, provided with suitable bearings for the horizontal main shaft 8. This shaft at its rear end, outside the head, is provided with a suitable clutch device 4 by which it may at will, be connected with and disconnected from a continuously running pulley 5.

Fast onthe main shaft wilthin the limits of the head is a bevel gear 6,that drives a mating gear 7, on the upper end of a vertical shaft 8, journaled in the head, said shaft at its lower end (see Figs; 2 and 5) having fast upon it a cam 9. This cam rotates continuously while the machine is in operation, between suitable gibs 10, on and to, reciprocate the horizontally arranged Said shaft 11 at sliding carrier 11, Fig. 5. its forward end,'at the left Figs. 5 and 6, carries the vertically arranged cutting block 12,- shown as provided at its upper end with a flange upon which it is seated, it being also provided. with a vertical axial wire passsage 13, into which the wire is fed from which a fastener is to be made. This cutting block is held fixedly. in position by a clamp ing screw 1-1 (see Fig. 6).

Immediately above the cutting block 13,

in the. rearmost position of the latter, is arranged acoiiperative cutting block 15. (see Fig. 6) the same being mounted in a block 16, removably secured in and to form a part of the machine head. The cuttingblock '15, is'shown in detailin Figs. 8 and 9 and is adapted in this instance, to act upon wire having a rectangular cross section. Said block as shown consists of a tubular mem ber flattened at one side to be acted upon laterally by the clamping screw 17, Fig. 6,-

which holds it in position; it is seated vertic'ally, againstan adjusting screw 18, which".. has a central orifice that registers with the Wire passage of the cutting block in order that the wire may be led downward through of the side i which enters said screw to and through said block. The block 15, see Fig. 8, has a slot 19, milled to and slightly past the center of the block and which intercepts a previously drilled hole that receives a pin 20 to close said slot, said pin'having a flattened base to constitute one walls of the rectangular wire receiving passage of 6% block.

When the cutter carrier 11 is in its rearmost position, at the right Figs. 5 and 6, the wire receiving passage 13 of this cutter block 12, registers with the wire receiving passage of the cooperating cutter block 15, above it, and at such time a length of wire is fed downward through the cutter 15, into the cutter 13. As said cutter carrier is moved forward by its cam 9, the cutter block 12, shears or cuts off the wire between it and its coiiperating cutter 15, and then serves as a fastener carrier to carry the severed length of wire which is now a fastener or part thereof, forward into position Fig. 6, to permit said fastener to be driven downward through the cutter 12, into the work beneath.

Directly beneath themovable cutter block 12, is a suitable workplate 21, the same being carried on suitable arms 22,. (see Fig. 5), depending from the machine head or a part thereof. This work plate has an orifice 23, through which'the fasteners may be driven into the work. a

To permit of needed adjustment of the movable cutter 12, to cause it always to register with its coiiperating cutter 15, the said cutter carrier 11 is made'in two parts as shown best in Fig. 5. The rear part containing the cam gibs, is formed at its forward or left hand end Fig. 5, as a socket to receive the other or forward part or member of said carrier. The said forward end is screw threaded at 24, toreceive a nut 25 a suitable recess 26, provided therefor in the socketed endv of the gib carjustinent of the tier member. Said nut is shown provided with pin holes, .to receive a pin by which said'nut may be turned to cause relative adtwo members, to vary the position of the cutter 12, as required. The

threaded member is grooved at its upper side to receive a screw 27 see Fig. 7, which holds the two parts of the carrier against relative" rotation and, for the purpose of clamping the parts in adjusted position, the socketed member, see Fig. 7, is split at one side and provided with a clamping screw 28, by which it ma be closed uponand to grip the contain'echthreaded member.. Referring new again to Fig. 1, thefm'ain shaft 3, at its extreme forward endis provided with a driver cam 29. This cam, see Fig. 4, plays between gibs 30 on the'vertically reciprocable driver carrier or bar 31, mounted in suitable ways inthemachi'ne head. At its lower end, said-driver barhas clamped within it a suitable driver 32 which,

arm 46 relative to the bell upon reciprocation of its carrying bar, is caused to descend through the nut carrier or. cutter 12, positioned beneath it, to drive the fastener therein, out through the lower end thereof, into the work positioned beneath and in contact with the work plate referred to.

The wire from which the fasteners are to be formed, may be taken from any suitable Inthe present instance, it is carried as a coil 33, see Fig. 1) on a reel support mounted on t e machine head. From this reel, (see Fig. 10) the wire is led down to the'tub'ular screw 18, previously referred to.

To feed the wire forward at the required times and in the required lengths, I have provided the following mechanism. Fast upon the main shaft 3, Fig. 10, is a cam 34, embraced by ayoked arm of a lever 35, fulcrumed at 36, on an arm of the frame. The depending arm of the lever 35, is grooved at 37, at its inner face, (see dotted lines Fig. 10 and full lines, Fig. 2) to receive a slide block carried by a pin 38, adjustable in the slotted arm of a bell crank 39, fulcrumcd at 40, also on an arm of the machine head. The

inwardly extended arm of said bell crank is marked 41, Fig. 11,

slotted radially to re-. ceive a block 42 to'which is fulcrumed at 43 a U shaped pawl 44. This pawl at its elbow is pivotally connected by a screw 45 to a second arm 46, loosely mounted on the fulcrum 40, and to hold in frictional engageis fast thereon, in suitable manner. Herein the hub of said second arm 46 (see Fig. 11) is arranged betweentwo friction washers 4 maintained in frictional relationship with the arm 46, by a spring 48, seated against a nut 49, threaded upon the reduced end of the fulcrum stud 40. The active or toothed end of said awl 44, stands opposite the continuous .wall

the said arm '46, and is held against undue movement relative to said arm 46, by a stop 51 on*the-latter. The arrangement is such that, if the pawl carrying end of the'bell crank be elevated, it

about its pivot 45, on and relative to the arm 46, to cause said pawl to free itself from the wire'or until it is arrested by the back stop 51-after which both arms will rise together. Opposite movement of the said bell crank, however, causes an opposite turning movement of the pawl 44 to'cause-its toothed end i to move to the right to grip the wire between which,

said end and the ide plate 50, after it being impossi le for the awl to turn further, the said two a rmswill descend together, this time, however, carrying thejw re with them. The frictional mounting of the carrying arm 41 permits of the relative movement of-the to the wire for the'purpose from, and engaging, said wire, .to feed the awlof freeing tself .ment therewith or withthe bell crank that of a guide way or plate 50 on I will first tip the pawl latter. 'rpince there canbe no feeding move 'ment ofthe. pawl until thisj-turningflmovement has been arrested by contact with the wire, it follows that there can be noslip between the pawl and the wire because, the.

great-tenths resistance to the travel of the cause the. wire to be fed Between the feed pawl 4A, and the tubular guide screw 18 I have arranged a pair of back stop pawls 52, (see Fig. 10,- '-they being held by a spring 53, always in frictional engagementwith opposite. sides oft-he wire, burp] at such an angle therewith, thatthey W1 cuttersyet will resist'and'etfectivelyarrest any retrograde. movement of the wire. These pawls are mounted in a suitable car ricr block 5st, secured in the maohine'head and which is provided with a guide way through which said wire 'iscarried to and between said pawls. The parts are so timed, that when the .wire. is fed forward for the new fastening and the fastener or; nail can rier is in its rearmost position to receive it and the feed pawl returns for a new; nip'of' the wireduringthe time in which the projccted wire; is, bein supplied to-th'e carrier, and carried forwar for driving. The machine may be usedwith or without an arid, and awl feed, but for mostclasses of work, i prefer to use both the awl and the awl feed. To thisend, (seeFigs. 1, 3 and 4:) I have mounted in the head,- closc beside.

the driver bar Shun awl'ba'r 55. This bar.

near its upper end,(see Fig. 1,) has a stud 56,

to which is jointed the upper end of a link 57, connected at its lower end, (see Figs. 3' and 13), with one arm of a yoke 58,'ful-' crumed at- 59 onthe machine head. Said' yoke is provided witha pair of rollers'or studs 60, 61, which run respectively on cams 62, 63, placed side by side on the mainfs'haft 3. These-cams operate to oscillate said yoke eifectively in both directions, thereby through the said link 57 to reciprocate said awl bar 55,-and giveto the awl, to be described, its vertical movement to cause it to enter and leave the'work. At its lower end, said awl bar,(see Fig. 13),-is provided 'wit-h a laterally extended foot 6 1, in whiclislides a block 65, having a depending arm 66 inwhich is clamped the awl 671 This block and its awl are therefore caused to move vertically with the awl bar to enter and leave the work as stated, and are caused to slide in the foot of said bar to furnish laterl'or feeding ,movement to the awl, by the follow mechanism. Said block 65, near its outer and, Fig. 13, has a vertical guide way 68, for a block 69 (see Fig. 14) fulcrumed at 70 in a depending arm 71 of a lever fulcruined at72 on the machine head. The upwardly extended arm of said lever is 'on the opposite end of the fulcrum72 (see Fig. 1) and, said upwardly.

sin'gle cams only, but a'single yoke, onebeing a leader and the I other afollower so to speak.

&

extended arm is grooveda t its inner or rear "face toreceive asl'ide-block, shown in dotted lines, Figs. 13, and 14,,lhos'lypmunted upon a stud 73, in theslotted-arm H, of a lever fulcrumed'at 7 5 on a stud on the machine "head. The upper end of said lever 74 is wire, the greater also. will be the grip to formed as a yoke, 76. having its arms provided respectively with rolls 7 T, 78', Fig. 13,

that travel respectively on cams 79, and 80, on the main shaft 3. Thus, at the proper times in the operation of said machine, said awl is caused to enter the work and form an opening Whilein the work said awl is caused to free from the work and is returned again transversely to the right into starting position, substantiallysimultaneously with which the nailcarrier 1s advanced mtoposition directly over the awl-opening to present its nail to'be driven by the dr ver as the latter descends, The two pairs of cams for operating the two yokes 58 and 76, are in effect since each pair operates While it is possible so to shape the cams for operating the awl as to give to the and the required rapidity of 'i'no'vement necessary to cause it to driver, it is.

clear itself of the descending cam action by means operated by the driver bar itself, in ordert-hat the movement may 1 be'accelerated while preserving an easy motion, and also to make certain that the said awl is always displaced in time and by the device which it must clear. For this purpose the driver bar, (see-Fig. 13) is provided, near its lower end, with a vertical slot 81, oifset near its lower end,'and which receives a roller stud 82, projecting laterally from a horizontally arrangedslide bar 83, mounted in the machine head. This slide a bar at its outer end, at the right Fig. 13, is

slot-ted to engage a crank'pin 8 l,'ona flange 85 of a hub 86, which is mounted in the machine head and within which is an eccentric bearing for the fulcrum shaft 72, of the awl moving lever.

As the driver bar. descends and before the driver has had time, to own take the awl, said cam slot 81 throws the slide bar 83 to the left, and thereby turns the crank pin 84 and its hub to the left, throw-' in the eccentric bearing for the fulcrum shaft 72 .to the right and imparting thereby,

through the lever 71, a quick outward or clearing movement to the awl, in addition to the movement subsequently to be given it by the cams acting withinthe yoke 76. On the return or upward movement of the driver bar, the fulcrum shaft 72 is returned to its that will facilitate the entrance I of the fastener suiiiciently to be driven. permitfree travel ofthe wire to the;' 7

,move transversely to the left to feed the work into posit-ion with said opening di- ,rectly beneath the driver, now in its elevated position, Thereafter said awl is elevated desirable tosupplement such 100 innermost position thus, in a different direction, again supplementing the cam action of the yoke 7 6.

The machine described is particularlyadapted to operate at high speed; all the cams are relatively small so that there is little inertia to overcome in starting and stopping them and the motions communicated from them to the various parts are all easy and capable of operating at high speed. The mechanisms themselves are simple and not easily thrown out of adjustment, so that the quality of wort produced is of the best. All the motions are adjustable to the necessary extent to lit the machine for driving fasteners of varying shapes and siz'cs.

What I claim as new and desire to secure by Letters Patent of the United States is 1.
