WIRE-FENCE MACHINE.

of-which the following is a specification.

This invention has reference to certain new and useful improvements in wire-fence machines, particularly to that type employed for the manufacture of a squaremesh fencing, composed of a pluralitv of running or longitudinal wires connected by transverse stay wires. In this instance the stays are united or connected to the longitudinal or running wires by forming loops in the bodies of the stays where they coincide with the intermediate running wires and wrapping or coiling said loops around said running wires; the ends of the stays being. preferably connected to the outside running or selvage wires by wrapping o'r coiling the plain ends of the stays around said selvage wires.

The object of the present invention is to embody in a machine employing a single stay-wire feed, wire-connecting mechanisms for simultaneously making two widths or two rolls of fencing; and it is accomplished,

by feeding the required length of stay-wire to said connecting mechanisms and operating such mechanisms in a manner to draw in the surplus amount of wire for forming a union between the stay and longitudinal wires, from opposite ends of said stay wire, and severing the stay-wire intermediate its ends into two stay-lengthand rs; ing or coiling the ends of said sta v-len;ih-- around corresponding marginal or selvage-wires of the res iiectivc widths or rolls of fencing.

A fence such as is capable of being made by my machine is not new with me. That is to say: I am not the first to have made a machine for uniting stays to longitudinal wires, where loops were formed in the stays and such loops coiled or wrapped around the longitudinal wires. One type of machine for manufacturing uch a fence included combined loopcls and coilers and a =recipro -atorv needle which fed the staywire from (:oiler to coiter. from whichastay was severed after each operation of placing the sta v-wirc across the wires -forming the fence and uniting such stay-wire to adjoining longitudinal wires: :1 second type comprise] a ma hine where the stays had their Specification of Letters Patent.

loops formed on a separate machine and such looped stays transferred or deposited on the coilers to have the loops coiled about the strand wires for uniting the fence wires; and a third type, a machine where-the stay-wire is projected endwise across the several longitudinal wires by a suitable feed and from such stay-wire is severed a staylength. This stay-length is then moved laterally and deposited on combined loopers and coilers, and during the looping and coiling operation the stay-wire is being project ed endwise across the longitndinalwires and moved laterally, whereby the successively fed stay-lengths are attached to said longitudinal wires. In this last-mentionedmw chine the looping and coiling operation begins at the center coilers and continues:

toward the opposite or selvage coilers drawing in the surplus wire from the/opposite ends of the stay-length. Thus the capacity of the machine is'greatly increased on account of its taking so little time to feed and attach a stay. In fact, it is safe to say that with such-a machine approximately twice as many stays could be attached in the same time as had previously been accomplished, but in neither of these machines is there shown or employed a single stay-wire feed' from which is severed a stay-length and such stay-length united to a plurality of wires forming tworolls or widths of fence simultaneously. Therefore, the present machine has considerable advantage over the known art. in that its capacity has been greatly increased; and the fact that it is apable of manufacturing two widths or rolls of fence simultaneously, using only a single stay-wire feed, renders more effective the operation of the machine. It is to be observed, however, that the machine is not limited to the manufacture of two rolls 'which shall be of the same width, as may be sup-- posed, but such .rolls may be of different widths. For instance in Fig. 2, which is a diagrammatic plan view of the loopers and coilers. two rolls could be made approximately 26 in width, or one made 26" in width and the other 32 in width. This is accomplished by adding one more coilers to the left-hand series and using the same or not as may be desired, of course regulating the stay-wire feed to bring about such a result.

That the invention may be more; ,fully.v

understood, reference is had to'tlie accom- 'panying drawings, forming a part of the specification, in which:

Figure 1 is a front! elevation of only so much of my machine'as is necessary to illustrate the application of my invention thereto; F ig. 2' is a diagrammatic plan view of a double series of loopers and coilers, showing the relative arrangement and spacing of such coilers, making it'possible to manufacture two widths or rolls of fence simultaneously. The view also shows a variable number of coilers in the two series, whereby a roll offence of one width may be made by one series of coilers and a roll of a differ- 'ent width may be made by the other series of coilers simultaneously; Fig. 3 is a plan view, of a'portion of the front part of the machine, shown in Fig. 1; Fig. 4 is a vertion of the machine, showing the positions assumed by certain of the parts during the feeding of the stay-wire across the series of line wires;-Fig. 7 is a similar view, showing the artsshifted, including the movable cutter for severing the stay-length from the stay-wire, which said parts also move the severed stay'length laterally into position to be connected to the longitudinal wires; Fig. 8 is a similar view, showing the parts returned to normal position with the stay length held in place and ready to be applied to the longitudinal wires; Fig. 9 is a section, as the same would appear on the line 99 of Fig. 3; Fig. 10 is a diagrammatic lan, showing in dotted lines, -a number oi the coilers of the two series, and a stay-length; also showing in what order the coilers of the two series are operated to start the loop- -ing and attaching of thestay-length to the longitudinal wires of the two widths of fence; Fig. 11 is a view similar to Fig. 10, but shows the second step in the operation of-the coilers; Fig. 12 is a view similar to Figs. 10 and 11, but shows the third step in the operation of the coilers. In this view the center cutter which severs the staylength into two sections, has been operated to sever such stay-length, however, the cut ter may be timed to operate at any time after the operation which has taken place in Fig. 10, as it is necessary to place a tension on the stay-length to facilitate in making a ti ht wrap of the inner severed ends around w at will be the top and bottom selvage or marginal wires of the two widths 'of fence.

Like characters of referen e denote corresponding parts throughout the figures.

' I have not attempted to detail or even i l I and 5.

outline the structural or frame parts forv supporting the operating mechanisms of the machine, asitmay be of any suitable character forthepiirposes herein;'nor do I de tail the power mechanisms which would ordinarily be associated with the operating mechanisms, as these too may be of any suitable character and applied and assembled in any suitable manner to accomplish the result described and aimed at herein.

1 designates a horizontal bed-plate or table, which is provided with a plurality of openings 2. These openings are arranged in two series, referred to as the right series and the left series. For convenience the right series numbers seven (7) openings and the left series numbers eight (8) openings, and such openings 2 constitute eoiler sockets, within which are mounted to rotate revoluhle coiler heads 3, see 4 The coiler heads 3, as well as the openings 2 of the two series are arranged in line with one another, as shown in 'Figs. 2 and 3: and the intervals between the adjacent coilers of the two series are graduated from one end of the series to the other, in accordance with the gradually increasing intervals between the line wires of the fence, which. as is well understood in-the art, are separated by progrtssively increasing intervals from the lower to the upper edge of the fence. In the present showing, referring to the right series of coilers, the intervalsbetween the coilers gradually increases, beginning with the outside or end coiler at the right-hand end of such series. while the intervals between the coilers of the left series gradually increases, beginning with the inner or end eoiler at the right-hand end of such series; or in other words, the

coiler for the selvage or marginal wire for the top of the fence of the right-hand roll of fence. adjoins the coilcr for the selvage or marginal wire for the bottom of the fence of the left-hand roll of fence, see Fig. 2. For convenience, I have indicated the individual coileis of the respective right and left series by the characters a. 71. c. (I. 1.. f. and g and an additional coilcr of the left series as 1:. indicating the sequence of operation of the coilers of each series, and also indicating, the corresponding coilers of the two series which work in pairs. since both series of coilers are in operation at the same time.

it will. be observed that thecoiling operatimrdocs not begin with the innermost (uilers g, f/ of the two series, but that the coilers (1,? G of the respective right and left series are first started,sec l*ig. l0. and just after such coilers have been rotated sutlicicntly to produce loops 1'. in the staylength ;i. the coilers b, I; of the two series will come into operation, and just after such coilers have been rotated sutiiciently to and f severed into two stay-sections in a manner which will be explained.

The left series of coilers includes one more coiler than is shown in the right se-" ries, the object of which is to produce a machine capable of making two rolls of fence of a similar width, or two rolls of varying width. By changin the coiler from a loopcr to an end coiler and cutting out the coiler 1L the present machine could be used to manufacture two widths of fence approximately 26 in width, whereas, if the coiler f is left as a looper and the coiler h as an end coiler, the machine could be used to manufacture two widths of fence, one approximately 26" in width and the other approximately 32"- in w1dth. The two coilers g g of the respective right and left series are timedto operate coincident with or just after starting the coilers f of the two series, but it is to be understood that the coilers g, g may be brought into action any time after the'looping operation by the coilers a, it which is necessary to place a tension on the two severed stay-sections of the staylength, otherwise, if the stay-length was sevcred between the coilers g, g before the operation of looping or attaching any other part of the stay-sections, it would be impossible to make a proper wrap of the inner ends ofthe respective stay-sections around the marginal or selvage wires. The means of severing the stay-length 7', from the stay-wire will be described.

The top portion of each coiler head 3 is in the form of. a detachable plate or disk 4 suitably secured to said head 3 and having its up er surface flush with the surface of the talile or bed plate 1, see F ig.'4. The plate 4 is formed with a segmental open-ing 5, see Fig. 3, the

divergent walls

6 and 7 ofv which are tangential to a circle concentric with thcaxis of. the coiler and somewhat grater in diameter than the diameter of the longitudinal wires. This construction of the plate 4, constituting an element of -the coiler head, produces in effect a head having in the upper surface thereof a segmental recess having the axis of the head located within its confines and disposed adjacent to the juncture of the "convergent nails oi: said recess. The wall 2' the opening or recess 5 is undercut, as

around "the top and bot-- shown in dotted lines in Figs. 3 and 6. This undercut edge of the opening therefore defines what may be termed a loop-depressing cam 8 designed to ride over and depress the looped portion of the stayto facilitate in said loop being coiled or wrappedaround its coinciding lon itudinal wire.

Dependent from and preferably integral with the coiler 3 is a hollow spindle 9, journaled in suitable frame parts, and allowed to rotate but preferably held against longitudinal movement. Immediately below the coiler head 3 is disposed a collar 10 encircling the spindle 9 and arranged to be reciprocated thereon for the purpose of lift ing or depressing the stay looping or coiling pin 11, into or out of operative position.

refer generally to the pin as 11; if it 1s an end coiler it has a hook 12, but if the pin is a looper, the hook 12 is omitted. The pin 11 is secured to the collar 10, and normally projects upwardly through the coiler head 3 at a point within the confines ofthe opening 5 semewhat in advance of the wall 7 and closely adjacent to the. outer willbi the normally projects above the upper surface of the plate 4, see Fig. 4, being retained in this position in a manner to be described. All of the combined loopers and coilers 3, with the exception of those at the ends of the right and left series, are identical in construction and mounting with the one just described, all of the heads 3 being mounted to rotate in the table-or bed-plate l. The end coilers are identical with the others, except as stated, the upper ends of their pins 11 are laterally deflected or hooked to better engagethe end portions of the respective stay-sections.

- The mechanism for actuatingthe coilersis such that they will be operated in series,

or in other words, the operation of corresponding coilers of the right and left series will be simultaneous, while the successive coilers of each series will be brought into action successively, -without, however, allowing the preceding coilers of each series opening. The upper extremity of thepin to complete their operation'before the op-' eration of the next coilers is inaugurated. Thus, .while the corresponding coilers of the two series will be the only ones operating in complete coincidence, several or all of the coilers of both series may be operating at the same time, since the last coilers of said series may come into action before the first coilers thereof have completed their operation, whether this is true or not, depending, of course, upon the number of braced by each series.

Carried on the lower ends of the spindles 9 are bevel pinions l3, and said pinions 13 are in mesh with and adapted to be driven by similar pinions 14 carried ontransverselydisposed short shafts 15 journaled in suitable 'franie parts, and on the inner ends of said shafts are carriedbevel pinions 16 having hubs 17 adapted to have a locking relation with segmental driving gears 18. These gears 18 are carried on an operating shaft 19 which may receive its power'froin any suitable source and in any suitable manner.

There are approximately thirty-five teeth 20 on each segment gear 18, and each pinion 16 machine.

series and the coder g of the left sehas approximately twelve teeth, therefore,

with each revolution ofthe shaft 19, the

shafts 15 will rotate approximately three tin ies, and the spindles!) will .be rotated a like number of times. Each gear 18 has a segmental lockingfiange 21 terminating at the opposite ends of the teeth 20. For

a given period Y during the rotation of shaft 19, it willbe 0 served that the gears 18 and pinions 16 will be in'n'iesh and cause the operation of the spindles 9, and during the remaining period of such movement, the spindles 9 will remain at rest and held against rotation by the engagement of the locking flange 21'with the hubs 17 of pinions 16, said hubs being suitably constructed to bring about such a result.

-To operate the coilers in the directions indicated'by the arrows in Fig. 2, I arrange the gears 18' for the respective coilers as follows, see Fig. 1-: Referring to the right series all the gears 18 with the exception of the gear for-operating the coiler g for the'top selvage or marginal wire, face toward the right-hand side of the machine,

whereas, the gear for -co'iler"g faces the ries, excepting coiler g of the rightries, all rotate in the same general direction; while the coilers of the left series and the coiler g of-t-he right series, excepting coiler g of the left series. all rotate in the same general direction, but in a direction opposite to the coilers of the right and left series: just above referred to. It will also be observed. by ref- 3 erence to Fig. 1, that the several gears 18 of each series are graduated as to their move- '1 ments or periods of operation, the gears 18 for the coilers a, a of the righi and left series having the most advanced position and therefore coming into action first, and the gears 18 for the coilr-rs f," i at the outer end of each'series and the. gears- 18 for the coilers g, g {at the inner ends of such series being the least advanced, come into action-last, in manner and for purposes previously explained.

During the rotary movement of the coilcrs 3, their pins 11 are adapted to be with-- drawn from their normal position, see F ig.

4, and subsequently restored to such posit-ion. To efiect the performance'of this function at the proper time, a series of cam levers 22, see Fig. 4, are fuleruined at the rear edge of the table or bed-plate 1 with their bifurcated front ends 23 engaging peripheral grooves 2-1 in the collars 10. The rear ends of the levers 22 carry rollers 25 disposed in cooperative relation with two cams 26 and 27 suitably carried by or mounted on disks 28 keyed or otherwise secured to a cam shaft 29, suitably carried in the machine frame and operated in anysuitablemanner. The cams 26 and 27 must he graduated to correspond with the graduation of the gears 18, for the reason, that the period of operation of each pin 11 with respect to thetperiod of rotation of its coiler head is the same, and therefore each cam must have the same relation to the corresponding gear 18. At .a predetermined point in the rotary movement of the coiler, its pin 11 isdrawn down by the roller 25 of lever 22 riding over the cam 26 which wilt depress collar 10\and'-pin 11 on spindle 9. Immediately upon the roller 25 leaving cam 26 it rides under the cam 27 which will operate to force the lever 22 in the opposite direction and raise the collar 10 and pin 11. Normally, the pins 11 are located at the front side of the coilers, see Figs. 3 and 6.

Associated with each coiler and normally located above the same is a presser foot 28, which may be of any suitable construction to perform the functions for which it is intended. Each presscr footis connected with or attached to a presser foot bar 29 disposed lengthwise of the table or bedplate 1, at the rear edge thereof, see Fig. 3. The !)1'(S 'Cl" feet. i' -oriiiall v occupy the positions shown in. Figs. 4 and G, and assistin the wrapping or coiling of the stay around the longitudinal wires. After the stays have been connectedto the line wires,

the presser feet are withdrawn rcarwai'dly to the position shown in Fig. 7 in order to permit the longitudinal wires and the attarhed stay-sections to be advanced or elev above the upper ends-of the pins llwvhen the latter are in their elevated positions. The rear edge 31 of the table 30 is located in rear of the positions occupied by the pins.

11, see Fig. 3, to permit which the rear edge of the table is indented by arcuate recesses 32 concentric with andhaving a radius substantially equal to the radius-of the adjacent coilers. Supported above the staywire-table 30 is a combined stay-wire guide and feed bar 33 connected to the presser foot bar 29 by end plates or straps 3a, the

' b'ars'29 and 33 and the connecting end plates.

or straps 34 constituting a transversely reciprocatory frame disposed above the table or bed-.plate '1. In the underside' of the stay-wire feed bar 33 is formed a stay-wire guide or groove 35, which, in the normal retracted position of the feed bar, is dis osed opposite a stationary stay-wire gui e 36 fixed to the table or bed'plate 1 beyond the right-hand end of the feed bar, see Fig. 3.

The stay-wire, which for convenience is referred to as k, may be fed.'fr0m any suit-- able source, through the guide 37, thence between the feeding

wheels

38 and 39 which have a predetermined movement and are adapted to feed in the stay-wire a sufficient distance so that there may be severed therefrom a stay-length, subsequently attached to the two sets of longitudinal wires Z, and severed. into two stay-sections. The staywire thence passes through the guide 36 and feed bares. 'Dhe'feed bar 33 is guided in its transverse movement by overhanging guides 40 secured at their front ends to the table or bed-plate l and engaging transverse grooves 41 in the feed bar. At the righthand end of the feed bar 33 is disposed a stay-wire cutter 42 arranged to pass across the inner end face of guide 36 and thus sever the stay-length j, from the stayfwire k, as the bar 33 moves rearwardly to carry the. stay-length to the coilers. The movement of the feed bar 33 and the resser feet 28 transi erselyof the table or ed-plate 1 is effected through the instrumentality of a rock-shaft 43, suitably supported and operably secured to the barv by bolts 47 and having their front ends disposed opposite shallow notches or depressions 48 in the rear face of the st-ay-wire-table 30, see Fig. 3. These tension devices or bars 46 are designed to clamp the stay-wire against the rear face of the stay-Wire-table for the purpose-of placing the same under sufiicient coilers. Also associated with the table 3() are a pl'urality of stay-wire depressions 49, see Figs. 3 and 9, in the-form of inclined blades carried at the rear ends of spring shanks ,50, the front ends of which are curved back, as shown in Fig. 9, and bolted to the table or bed-plate 1. To accommodate the depressors 49 the stay-wire-table 30 and the feed bar 33 [are provided at their rear edges with open ended slots or notches 51 and The bottom face 53 of the depressors are slightly inclined from the horiz ontal .in order that as the stay-wire is depressed it'will also be urged forwardly into engagement with the front face of the table 30.

Reference will now be had to the cutter for severing the stay-length j, into twosepatinct roll or width of fence: 54 denotes a cutter blade mounted to have a reciprocal movement on the table or bed-plate 1 beneath the presser foot bar 29 in a guide 55, located preferablybetween and adjacent the end coilers 9 g of-the i right and left series of coilers, The forward or cutting end of the cutter 54: cooperates with a stationary cutting member 56 seated in the rear edge of the table 30, see Fig. 3. The rear end of the cutter 54 has. a pivotal connection with links 57 and said links have a pivotal connection with one end of a bellcrank lever 58 fulcrumed at 59 inz'a bracket 60 secured to the rearedge of the bed-plate 1. The opposite end of said bell-crank lever 58 carries a roller 58 adapted to have a cooperative relation with cams 60 and 61 carried'by a disk 62 fin the shaft 29*. The cams 60 and 61 are so dis osed on the shaft roller 58, approximately coincident with the operation of the inner end coilers g, g of the respective right and; left series of coilers, causing the-cutterfi t to be moved forwardly severing the stay-length j, into two separate sections, see Fig. 12,.and as the cam 60. rides from beneath the roller 58", the cam 61 will ride over and engage roller 58 returning the cutter 54 to inoperative position, seen in Fig. 3.
