STAPLE-TACKER.

Specification of 'Letters Patent.

Patented Nov. 26, 1907.

Application filed May 6.1905. Serial No. 259.140.

To all whom it may concern:

Be it known thatI, PERLEY It. GLASS, a citizen ofthe United States, residing at Boston, county of Suffolk, and State of liiassachusetts, have invented an Improve ment in Stagde-Tackers, of which the following-description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing like parts. My invention relates to machines for forming'and driving metallic fasteners, such for instance as wire staples and particularly to such as form the fasteners from a continuous strip of metal or wire.

In staple forming and driving machines at present in common use, the forming and driving mechanism proper comprise an anvil across which the metal strip is fed, a suit able former to form or shape the strip over and upon the anvil and a driver to drive the staple after the anvil has been withdrawn. Suitable strip leeding and cutting mechanism also are provided comprising, usually, a pair of feed wheels and cooperating cuttors adjacent. thereto, and means is pro.

vided for varying the feed or" the wire so as to very the lengths or sizes of the staples. if, however, the feeding and cutting devices remained in lixcd relationship to the anvil, any variation in the length of feed would merely vary the distance to which the end of tllOStllj'l would be fed beyond the anvil, consequently that leg of the staple that is formed from the portion of the strip so fed beyond the anvil would alone be varied, and the leg formed from the portion of the strip between the cutting device and the anvil would remain constant. To obviate this, and to insure equality of length of the staple legs, whateverilw actual lengths thereof, or if a given inequality is desired, to preserve such inequality whatever the feed of the strip and the resultant actual lengths of the staple legs, it has been customary to adjust the feeding and cutting mechanism or the cullingmechanism alone toward or away from the anvil, simultaneously with and jiropottioiuti(ly to any variation in feed of the strip, so that the length of strip fed at any given timewould be balanced equally or properly at. opposite sides of the anvil and thus preserve the required equality in length ol the staple legs. Machines of this description are illustrated in the patent to Hannn M1681, dated March 3, i891, and Hanna and Eaton, No. 571,227, November 10, 1896.-

and the strip feeding and cutting mechanism,

and I accomplish this in part by maintaining the more complicated feeding and cutting devices in lixed position, thus eliminating the objectionable complicated connections above referred to as necessary when said devices are adjustable, the simpler staple forming and driving means being made the adjustable memlwrs.

The nature of my invention and other objects and advantages thereof, will be more clearly apparent from a description of one embodiment thereof which has been herein selected for illustration and which is shown in the accompi'tnyiug drawings, and its scope will be pointed out in the appended claims.- .111 the drawings, F gurc 1 is a front ele vation of a machine embodying my invention; Fig. 2 is a right hand side elevation of Fig. 1; Fig. 3 is a left hand side elevation of Fig. 1; Fig. 4; is a perspective View partly in section of the staple forming and driving mechanism and of the strip feeding and cut ting mechanism, the parts being in section;'

Fig. 5 is a vertical sectional view on the line 5-5 Fig. l Fig. 6 is a sectional view on the line (j-6 Fig. 1; Fig. 7 is a sectional view on the line 7-7 Fig. 2; Fig. 8 is a sectional view on the line 8-S Fig. 2, and Fi 9 is a sectional view on the line 99 Fig. 2.

In the embodiment of my invention herein selected for illustration, the mainframe l ofthe machine is provided with bearings for the main driving shaft 2, upon the rear end of which is loosely mounted a driving pulley 3, which may be operatively connected with the driving shaft when desired, by a suitable clutch mechanism 4 operated through a treadle connectionj z'i.

Projecting laterally to the right from the I forward lower portion of (Figs. 1

' jaw of the .ftbnt face with a the machine frame and 2) are the supporting studs 6, upon which is slidably mounted the driver hcail 7.; The driver head is provided on its guide-way 8, Within which is carried the staple forming and driving mechanism proper said driver head 7 being adjustable laterally 'as hereinafter described to allow for adjustment of said mechanism toward and from the strip feeding and cutting mechanism. The forming and driving mechanism comprises a vertically reciprocating staple former 9 mounted to slidein the guideway 8 (see Figs. '1, t and 5) and having secured to its lower end a former die 10 provided on its rear face with a staple forming groove 11. For vertical reciprocation the staple former is connected by means of, a stud 12, rojectin 'to the right therefrom, with a bel crank "ever 13 (Fig. 2) pivoted at 14 upon the frame of the ma chine and having an upwardly projecting arm 14? provided with a cam roll 15 for actuation by a cam 16 on the main shaft 2.

Within the lower portion of the supporting driver head 7 (Fi s. 5 and 9) is the horizontally sliding anv' member 17, having at its forward end an anvil portion proper 18, which for the forming of the staple is adapted to be projected into the path of the staple former 9 by means of a lever 19 (Figs. 2 and 5) pivoted at 20 to the frame of the machine and having at its upper end the cam roll 21 engaging the cam 22 on the main shaft 2. Inf order to prevent rotation of the anvil member 17 in its supporting driver head 7, said anvil member is provided (Fig. 9) bebind the frame head, with the laterally projecting arm 23 having a squared end 24 to slide Within the rear forked end 25 of the stud 26 fixed to and .projecting'rearwardly from the supporting driver head 7. To reciurocate the anvil, the arm 23 is provided with a squared bushing 27 (Fig. 9) to be engaged by the forked lower end of the anvil operating lever19, said bushing being of a len th sufficient to allow it to move laterally Wit respect to its operating lever 19, upon lateral adjustment of the supporting driver head 7. Te allow the lever 19 to have ltSl movement/.pven though the anvil 17 may be accidei tally prevented from movement at an time, as for example by the presence. of a roken driver in the guideway of the forming-' and driving mechanism, the rear fork 28 (Figs. 2 and 5) .of the lever 19 is provided with. a socket 29 carrying a spring stud 30 which. engages the bushing 27 at all times, the tension of the spring 31 of the stud being sufficient to move the anvil member 17 forward under. normal conditions but adapted to )"l6lLl-',tO allow for movement ,of the lever 19'when the anvil is prevented from forward movement.

. Within the guide-way 8 (Fig. 4) and pref- -7) upon thin faces and having upon erably also within an auxiliary guide-way 32' or the sta is former 9 is carriedthe driver 33 oft estaple driver 34, said driver bar terminating at its upper end (Figs. 2 and 3) in a horizontal transverse dovetail projection 35 entering a corresponding slide-way 36 in the lower extremity of a driver bar actuator" 37 mounted to slide vertically in a fixed guideavay 38 upon the upper front portion of the machine "frame. The sliding connectiori between the driver bar 33 and the ex-" tenslon 37 thereof provides for the lateraladjusting movement of the forming and driving mechanism with respect to the wire feeding and cutting mechanism above referred to, to provide for varying the lengths of the stapies. The actuator is operated by a strut 39,

which in turn 18 actuated from the spring arm 46, pivoted at 41 in an upwardlyextended arm 42 of the machine frame.'

The spring 13 which furnishes ower for the arm 40* adjusting means consisting here (Fig. 1) of a is provided with suitab e tension ratchet 4.4, to a stud 45 of which one extremity 46 of the spring is secured. A springoontrolled pawl 47, .pivoted at 48 upon the frame arm 42, serves to hold the ratchet in adjusted position and the latter may be provided with ahandle l?) to facilitate adjustment of the spring tension.

In the operation of the machine the driver is raised against the tension of the spring 43, by a cam 37, (Fig. 1) on the forward end of the main sl'laft 2. 37* on the driver bar actuator 37 and lifts the same until the highest point of the cam' This cam engages a foot' passes from under the foot 37*, when the driver is driven d own' sharply by the spring 43.

The lower end of the guide-way 8 (Fi s. 1

and 5) carrying the staple forming and riving mechanism, is provided with a suitable throat 50, through which the staples are driven by the driver into the Work. 4

To adjust the staple forming and driving mechanism with respect to the strip feeding and cutting mechanism to be hereinafter described, the driver head 7, which carries the former, its rearwardly extending pore tions provided at its upper side (Figs. 1 and 2) with lug 51 having a rearwardly projecting stud 52 engaged by the forked arm 53 (see Fig. 7) of an adjusting lever 54, pivoted at 55 (Figs. 1 and 2) to the main frame of the machine. Upon either side of the lever 54 are secured also to the machine frame, the arc-shaped guides 56 graduated at 56 (Fig. their outer sides notches 56 correspondin with the graduations 56*, said notches to ie engaged by a spring pawl 57 (Fig. 1) mounted in a slot 58 in the said adjusting lever 54, whereby raising and lowering of the lever ef; fects the lateral adjustment of the driver head 7, and consequently of the staple forming and driving mechanism with respect to the Wire feeding and cutting mechanism. Stop screws 59 at either end oi the graduated guides 56, serve to limit the ad ustment or the lever 54 and of the mechanism connected there with.

Adjustment of the rod 70 is ell'ectcd by means .of a nut 73 (Fig. 3) seated upon the upper surface of the arm 72 and the rod is priwcnted from turning in the arm. 72 by mcnns of a key 74 in the arm wl ch cngz'iges a groove 75 in the side of the rod 70.

For separating: the feed wheels for initial insertion of the metal strip or wire from which the staples are to bc lOllllitl, the swinging arm or (Fig. 6) oa'irving the lower feed wheel 65 provided with the lu; 7o through which passes a rotatable stud 77 carrying an eccentric 72; that is providcd with a handle 79 (Fig. 3) whereby the stud may be rocked to cause the eccentric to depress the arm 67 and move the iced wheel 65 away from the upper feed wheel (31, the spring 69 serving to bring the. whccls together again bearing at opposite sides of and upon the metal strip to be fed.

To actuate tlu-Rloed wheels rho-shalt o2 upon which the upper feed wheel 61 mounted, has a ratchet 80 (Figs. 3 and (3) adapted to be o 'iorated by ratchet pzm'ls 81 (Fig. 7) mounted upon a pawl cnrri r S2. which in turn is mounted iul rotation. upon the feed wheel shzii't $2.

The pawls hero shown (Fig. 3) are three in mu'nbcr and in- -creaso in length successivel 'l'ron'i lcit to right by an amount equal to one third oi the distance between successive ratchct teeth ,on the ratchet 80, thus providing for lincr graduation of adjustment of the nuchotnnd eons'erjuently of the wire lccd, than would bc 60 gear 83 (Fig. 7 with which engagcs IL correspending segmental gear 84 upon the lower extremity of the rocking lever 85, pivoted at so, to the frame of the machine and having a forked end 87, spanning a cam 88, upon the main shaft 2 of the machine.

To impart adjustment to the shield 85), the collar ()0 (l ig. (5) is provided with a segmental gear 91 adapted tobe engaged by acorrcsponding segmental gear 92 upon the rocking arm 92 depending from a sleeve )3 pivoted upon the stud 94 carried by a lug lit)" of the bracket (30. the sleeve 93 thereof is provided with an upwardly extending arm 95 which is connected 1 j; a link 96 with a lug 97 (see Figs. 2 and 7) on the hub of the rocking lever 54 so that when the staple 'l'orming and driving mechanism mounted upon the driver head 7 is adjusted laterally by meansuo'l the lever 54 to vary the length of tl staples, the pawl shield 89 will be simultaneously adjusted to vary the engagement ol the pawls 81 with the-ralchctho and consequently to regulate the iced proportiona-tclj' to the adjustment of said staple forming and driving mechanism.

In case it is desired to form the staples with legs ol dill'crcnt lengths the food may be varied iinlcpciulently oi the adjustment; of the staple l'orming and driving mechanism, and lo this end the stud 98 (Fig. 7 by which lllO link J6 is attachedlo the ling 97 of tlic adjusting arm 54 is made as an ccccnliic stud EH) and thc lug, S)? is u'ovidcd with a split bcaring' or hcad having a tightening bolt 101 to hold thc ccccnt'ric stud in adjustcd position. By loosciling the bolt 101 and turning the ccccntric stud 9!), the linlcniay be niovcd to lclt-or right and thus through the lcvcr )5 (Figs. 2) and (5) and collar 91 adjust the pool shicld over the rntchct S0. to uncover the tooth thcrco'l tor a grcntcr or less portion of the strolv'c ol' the .l'ccd pawls then-by to loud the staple wire a grcatcr or loss distance ovcr the anvil, indcpcndontly ol any adjustment of the staple forming and driving inccllanisni toward and 'l'rom tlic 'l'ccding' and culling mechanism. Thus, the staple log on the far side of the anvil will be To rock the arm 92' reciprocating .of greater or less length than that on the near side according to whether the feed is lengthened or shortened.

The mechanism for severing the blank or length from the strip prior to the forming of the'fastener or staple thereon comprises the under and upper cooperating cutters 102 and 103 res ectively (Figs. 1 and 4), cutter eing stationarily mounted adjacent the staple forming and driving mechanism,

inthe bracket 60 at the inner end of a strip guide-way 104in said bracket, which serves to conduct the strip from the feed Wheels 61 and 65 to the forming and driving mechan per cutter 103 (Fig.- 4) is se-' ism. The u cured to a block 105 bolted to a vertically slide 105 which is mounted to slide in suitable guidew-ays 106 on the bracket 60 and is supported normally in elevated position by means of a spring 107 located within the vertically drilled bore 108 in the reciprocating slide 105 and interposed between astationary stud 109 projecting upwardly from the bracket 60 and a screw plug 110 in the upper end of the bore 108. To depress the cutter 103, a rocking arm 111 (Fig. 4) pivoted at 112 in the frame of the machine is provided, which contacts preferably with the head 113 of the plug 110 at the top of the cutter block 105, the ever 1 1 1 being actuated by a cam arm 1 14, also pivoted upon the stud 112, and having a cam roll 115 which is actuated from a face cam 116 in the main shaft 2. To provide vertical adjustment of the upper cutter 103, an adjusting contact screw 117 is interposed between a lateral extension 118 of the arm 114 and upper surface of the cutter actuated arm 11 1.

' As shown in Fig. 4, the cutting edge 102 of the lower cutter is angularly positioned .,across the path of the staple strip and the upper cutter edge is similarly positioned to cooperate therewith, to effect adiagonal cut which the fastener is to stopping, any suitable means ma transversely of the'strip,

whereby the ends of the staple legs will be pointed to more easily enter the work.

The strip or wire 119 (see Fig. 1) from be formed, may be carried in any convenient manner, as by a reel 120, upon the arm 121, secured to the machine frame. v

To prevent rebound of the machine at be provided, but as here shown the mam shaft 2 is provided with a friction wheel 122 (Figs. 2 and 8) cooperating with a friction stop consisting'of a metal friction ball 123held in a bracket 124 depending from the upper arm of the machine frame and constantly pressed by the spring stud 125 toward the conver ing rim of the wheel 122 arid the interior wa 1 126 of the bracket 124.

Preparatory to the operation of the machine the strip or wire is threaded between the feed wheels 61 and 65fand alongthe the under guide-way 104' to the staple forming and rivin mechanism. When the machine is starte the feed wheels are rotated by the ratchet and pawl mechanism 80 and 81011 the shaft 62 of the-feed wheel 61 to cause a sufficient length of the strip to be fed over the anvil 18, which at this time projects within the path of the staple former 9. The

staple former 9 then descends and as it meets or contacts with the strip of material and. presses the same firmly upon the anvil 18, at.

the same instant, the upper cutter 103 in its descent, severs a staple length of material from the strip. Furt er descent of the staple forming member 10 serves to bend the severed portion of the strip over and down at both sides of the anvil 18 to form the or fastener. from the driver, w 'ch has in the meantime been raised 'by the cam 37 now drops from saidcam and, under the influence of the spring arm 40 drives the staple into the work, which latter is firmly held by the operator against the end of the throat 50 (Fig. 4). When during the operation of the machine,

it is desired to vary the length of the staples for the particular work in hand the operator lowers or raises. the adjusting lever 54, and through its connection described moves the staple forming and driving mechanism tofastener forming strip is fed e ually to both sides of the anvil 18, so that t e legs of the fastener will be of equal length, as under theseconditions the strip is fed as much further beyond the-anvil as the latter is adjusted from the strip severing mechanism, or vice versa. Some manufacturers, however, desire staples having one of their legs longer than the other and they may readily be had with my machine at any time and to any e25- tent by adjusting the eccentric stud to move the ratchet shield 89 over the ratchet 80 independently of the adjustment of the staple forming and driving mechanism.

Inasmuch as the respective movements of the staple former,
