WIBE-NETTING MACHINE.

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wire-fence machines and to the manufacture thereby, of wire-netting with substantially polygonalshaped meshes, in which the wires are continuous throughout the length of the fence, being twisted or interwoven together as they travel through the machine.

One of the principal objects of my inveny tion is to form the fencing or netting by twisting iii:l wires together :is they are coniinuonr-:ly advanced through the. machine7 thus producing the fabric with great regularity und rapidity.

y Another objectof my invention is to feed the. wires, from convenient reels or coils containing large quantities of wire.y into direct twislers, which, while capable of rotation in either direction.y are mounted in a stationary framework without lateral or longitudinal movement, said twisters being adapted to produce a righthand, and then by a reverse movement, produce a lefthand twist of the same amount7 and vice versa, thereby pre` venting the entanglement of the stock wires in the rear of the machine.

Another object ist@ provide another series of twisters, each capable of making what is known as a reverse twist, that is :-one in which portions of the wires imnie icly in advance of the twister, assume s;Y brins, while :it the same time, rear portion.A of the wires. immediately behind the't\i'isl;er. assume spiral forms of the opposite hand. 'lhus each of these reverse twists is .cont posed ot' two parts. one of which is rightliainl spirals and the oi her lcfthand spirals connected :n the center of the twist.

Anothfiier obliwt of in v invention is 4to S0 arrange the mecha sin for conducting these two kinds ol' twisting operations, that they are perform-'i nt the same time, thereby making one ros ot each kind of twists across the fabric :substantially simultaneously, i (3.

which further conduces to speed of manufacture.

.Another object of my invention is to pro-` vide .a revolving framework or drum for carrying and operating the reverse twisters, during the revolution of said framework, whereby, in coperation with the direct twisters, the fabric is formed continuously during its progress through the machine.

Another object is to so construct and arrange the direct twisters that they also serve as means for directly placing and holding Vthe wires insuch positions that they will be i,

properly received by the reverse twisters as these latter revolve with their drum, thereby cbviating the necessity of providing independent shifting mechanism for transferring the weft-wires from side to side, as has been heretofore customary.

By means of my invention wire-netting or fencing may be made with continuous substantially straight edges or selvage wires, which may be either single, double or triple, and with meshes of general hexagonal form between the, marginal selvage wires; and in addition to this. it may be constructed with substantially` straight intermediate wires running longitudinally through the centers of the hexagonal meshes, thereby stren hening the fabric and making it. more rigid and capable of being thoroughly stretched on the posts or supports for its ultimate use, without sagging or narrowinig.

Other objects and details o my invention will hereinafter appear.

Referring now to the accompanying five sheets of drawings which form part of this specification and in which like characters denote like parts: Figure 1 is a rear elevation of the machine, Fig. 2 is an elevation of that side which is at the left of Fig. 1, Figi'. a vertical, trmisvorse sectional elevation taken on thi; ie li.- l. Fig. 4 a reni" elevation of the top of iho machine slioning the revolving twist- 100 ving-drinn carrying the rotatable reverse twisters and part of the mechanism for operating the same; the stationary bearingian' containing the first series of direct twsters having been removed to more 105 clearly show the construction and operation of said twisting-drum. Fig. 5 is a transverse section of a portion of the twisting-drum taken on the line V--V of Fig.

tion of the twisting drum, showing one of the supporting members for the reverse twisters removed therefrom, the rack-bar operating said twisters being shown in elevation. Fig. 7 is a longitudinal section of one of the reverse twisters taken in a plane at right angles to the Longitudinal section thereof, shown in Fig. 5. in order to fully 'illustrate this portion of my apparatus. Fig. 5 is a rear elevation of the upper part of the machine, the cap-member of the 'statlonary bearing bar for the direct twisters having been removed for clearness of illustration. Eig. 9 is a vertical transverse section taken on the line IX--IX of Fig. 10, one of the tubular twisting fingers being shown in section and its mate, mounted in the same twister-head, being shown in elevation. 'Fig 1() is an `illustration of a por tion of the stationary bearingbar for the direct twistcrs with the rear cap-member removed therefrom, showing the rear of the said twisters, their gears and the actuating rack therefor. Figs. 11, 12, 13 and 14 are detailed views of portions of the twisting mechanisms showing the different positions which the wires assume as they pass into the machine and through the twisting mechanisms thereof; indicating the operations of twisting as follows :--Fig. 11 shows the positions of the wires before the twisting operations begin, Fig. 12 shows the positions of the wires after the first set, or direct twisters, have been turned one rotation. It should be noted that beginnin with the positions shown in Fig. 11, the rst half rotation of the twisting fingers lays the adjoining wires-'across each other and across the intermediate strand-wires, in case these vlatter are used. Fig. 13 shows the positions which the wires assumeafter the first set or direct twisters have rotated three times, thus 'completing their work for the row of direct twists shown in this drawing, and the second set or revolving rotaryreverse twisters have accomplished part of one rotation and a part of a revolution with the drum. Fig. 14 shows the positions which the wires assume just before they enter the advancing line of receiving-notches on the revolving twisting-drum, the tubes of the direct twisters having been previously turne about three rotations as heretofore stated; and the secondary or revolving rotary reverse twisters have finished about one rotation and a further fraction of a revolution with the drum, thereby continuing their woreA on theprow of reverse twists shown in the upper part of this figure. This reverse twisting is completed just before the wires pass from the lower part of the drum as shown `in Fig. 3. Although in the illustrations, the direct twists are each shown as farmed b3 about three turns of cach twisted wire; and the reverse twists -shaft 4 as shown.

are each shown as formed by about two turns of the wires on each side of the middle of the twist, one side being about two turns of left spirals, and the other side being about two turns of right spirals, l wish it understood that'my machine and manufacturc may be adapted to make any number of turns desired, in any of the twists to best serve the purpose intended. rl`liis I can accomplish by adapting or adjusting the twisters to rotate any desired number of times during their operation, as will be readily understood. Fig. 15 is a fragmentary detail view of a portion of one style of my finished wire-netting or fencing, showing at the lefthand side, the marginal strandwire, which may be single, as drawn, or may be double or triple, and twisted into cable form as desired. In this illustration the meshes are shown as hexagons. divided however, into ltwo parts by intermediate longitudinal strand-wires, about or with which the other fabric wires or weft-wires are coiled shown. Fig. 16 is a fragmentary view of a portion of another style of netting or fencing made on the machine, in which the intermediate longitudinal strandwires are not used, the meshes in this case being substantially hexagonal. Fig. 17 is a fragmentary view of a portion of a fabric made by the machine, showing a straight selvage or marginal wire and the mesh-wire coiled around the same in alternating righthand and lefthand twists. Fig. 18 is a detailed view of a marginal direct twister showingI a straight selvage or marginal strand-wire passing through the center thereof, and a mesh-wire coiled around the same by the diagonal tubular finger of said twister. Fig. 19 is a detailed view of a somewhat slightly different form of marginal twister to accomplish the same result as shown, the strand-wire in this case passing eccentrically through the body of the twister, but issuing concentric therewith, through the end of the inwardly detiected tubular finger thereof, as shown.

Referring now to the characters of reference on the various drawings which form part of this specification :dThe base of the machine is indicated at 1.,.which may be set upon a suitable foundation and secured thereto by anchor bolts as shown; mounted on this base are the two side-frames 2, which are of somewhat similar construction, but right and left- The base 1 also supports the side-standard 3 which carries a illow-block or bearing for the driving- The side-frames, as shown, are provided with various recesses, supporting ribs, seats and bearings, in or on which are mounted the various parts and mechanisms of the machine, and means are provided for 'securing and adusting the same thereto. in the end of t e drivingthereof.

shaft 4 tht` inainfdrivingbelbpulley 5 mounted and. providetil with the maiirdriving-belt (i connected with any suitable source of power; not shown. On an intermediate portion ot' the driving-shaft 4 the main-drivinggear i' is mounted, which meshes with the. gear 8 mounted on the intermediate shait l". On the other end of the shaft L: mo inted the gear l0 which meshes wth he girar 11. which latter gear is mounted and secured on theI end ol' the twisting drunwshatt 1:2. The revoluble twistingrdruint indicated in general as 13,'

is mounted on he drum-shatt- 12 and carries a pluralityy ot rotary twisters 1t, each ot' which ha:` a twisting slot 15 and a wear plate 16, these twisters being adapted to rotate by the gearieeth 1T, which form part The twisttrs 14 are mounted and supported in the bearingmeinbers 18, which are shown as ot' Lsection. but may be of any other convenient shape. The bearing-members 18 are provided with longitudinal grooves 19 therein Aand with circular openings 20, which form bearings for the twisters 14. i

The supporting members 18 are shown in pairs secured in place and together by means of bolts as shown, whereby the twisters may be mounted or demounted as desired, for replacement or repair. In the rcntrant angle of each of the supporting members 18 are the notched or beveled openings 21 opposite each `end of each twister 14, said beveled openings being t0 proijide the necessary clearance and form substantial parts with which the wires may contact, and also serve as passages for supplying oil to the bearings of the twisters 1i. The bearing-members are also provided with a plurality of tapered notches formed therein opposite the center of each of the twisters 14, said notches forming receiving guides wherein the advancing wires pass into the twistcrs during the revolutlon ot' the twisting-drum and eventually pass out of the saine, as said drum continues its revolution as indicated generallyl on Fig. 3

o'tl the drawings.

A number of rack-bars 23 are slidably mounted on the tvistingfdrum and provided with teeth 2li. ich teeth nit with the gcaz--tf--eth 17 of the rotary rev Y. twister-s 14. The ends ot the rack-bars are pro vided with otl'set portions on which are rercluhly mounted anti-friction rollers 26 which are adapted to contact` with and be operated b v the stationaryvtwisting-cant :'27 secured to the frame of thtA machine as shown. and the antitrietion rollers on the other ends of the Said rack-bars are adapted to contact with and be operated by the stationary return-cam 28, secured to the opposite trame. The operation of said rackbai-` and the ctmseouent rotation of the relverse twisters 14 is accomplished by the revolution of the twisting-drum in coperation with the twistingfani 2T and thtstationary' ie`tiii'ntz1m 2H. :is lniretofore de scribed.

The stationaryv bar which serves to ro tatably support the direct twisters is indicated as 29 and is provided with a forward y portion 30 having a groove 31 formed t therein; 32 is the removaliile side cap-memN ber of the bearing-bar 25) and is a groove formed therein. The rack-har is slidi ably mounted in the

grooves

31 and 33 as shown, and provided with teeth 33 on a portion of the upper edge thereof` which mesh with gears It on the ends ot the .stationary direct twisters 3T. 'lhe intermediate cylinlrical spindle portion ot' the direct twisters is indicated at 38, while 39 are circular holes in the stationary bearingbar which forni bearings for said direct twisters; oil for the lubrication ot which, is supplied through the oil-hole 40. The direct twister-s are each provided with an enlarged cylindrical head 41 shown as formed integral with the intermediate cylindrical spindle portion thereof, while 4Q represent cylindrical holes in the forward portion of the bearing-bar 29 to receive and form bearings and supports tor snif lai-ged heads 41. The intermediate it? ry direct twisters are each provided with pair of tubular fingers arrenfr l 'lh nally flaring, with their ends sp sired.

44 are central holes through the direct twisters for the passage of the strand-wires therethrough.

43 is a straight twister-tinger ot the marginal direct twister, the end ot which is eccentric with the twister so as to produce a certain amount of twist in the marginal or selvage wire, as tlzf inrsirwirc is being wound with it, as shin-'n in Figs. 11 to 1h inclusive.

As shown in Fig. 1i?, 13b is a marginal twister-linger, the delivery end of which is concentricall),7 located -vith respect to the twister for delivering [lic marginal strandm wire straight. with; twisting.

4.1 are the sui. tntiaily straight selvage4 or ,maro nl stra l-wires which are delivered oncentrif-ally nl' the marginal twisters, as descimeil herein. The. intermediate strand-wires, where usetlt are marked 45 and enter through holes Sii in the members4 3() and 3Q.

45a are selvage strandwires which are delivered eccentrically by the marginal twister and are thereby intercoiled or twisted with the mesh-wires as shown at 48 and 49a, this :t'orm being made by the marginal direct twisters shown in Figs. 11 to 14 inclusive.

46 are mesh-Wires or weft-Wires, and 47 to correspond with the mesh and twist i' twister.

49 are lefthand twists, but otherwise the same as the twists 48.

48d are righthand twists, each formed of a selvage wire and a mesh-wire which are twisted together and around each other by the form of marginal twister shown in Figs. 11 to 14 inclusive. 49 are lefthand twists, but otherwise the same as the twists 48a.

48b are intermediate righthand twists of the weft-wires made by the form of intermediate direct twisters shown in Figs. 3, 9,

-11, 12, 13 and 14; while 49b are intermediate lei'thand twists of the weft-wires, but otherwise the same as the twists 48.

50 are intermediate reverse twists formed by the reverse twisters 14.

It will be noted that the direct twists eX- tend in a substantially continuous row across the fabric, while the next rows of direct twists on either side thereof, are of the opposite hand. The reverse twists as shown are composed'of duplex. spirals, one end of each being formed of righthand spirals and the other end of each twist being formed of lefthand spirals. It should also be noted that the

direct twists

48a and 49" when made in connection with the marginal wires 453 are, as shown in Figs. 15 and r16, each composed of two spirals intercoiled about each other, that is -the marginal wire is coiled around the weft-wire, and the weft-wire is also coiled around the marginal wire, thus making a very secure connection. This may be accomplished by the action of the tubular fingers of the marginal twister shown iny Figs, 11 to 14 inclusive, which^are eccentric with respect to said twister, thereby coil ing said marginal wire and welt-wire around, each other to the degree shown. It should,

however, be further noted, that by increasing the tensionof the marginal or strand wires, in any case, these may be maintained substantially straight as and. where the mesh-wires are coiled around them. It should also be noted that by decreasing the tension of the strand-wires, in any case, they maybe made wavy, or to assume a spiral form as and where the weft-wires are coiled with them, thereby forming twists in bot-h of these wires and thereby more securely locking them together, if desired. Thus by the operation of the mechanism shown, or by the adjustment of the operation thereof,

or by a; combination of said mechanism and adjustment, any of the styles of direct twists shown herein may 'be made.-

A form of netting is shown in Fig. 16 from which the intermediate longitudinal strand-wires are omitted, thereby forming a netting with stubstantially hexagonal meshes, and this form, as well as that` shown in Fig. 16, may be made on the-machine.

By varying the distances between the twisters and between the other partof the mechanism which operates between the varidus wires, a net-ting of any size, mesh or proportion can bel made, andin ease lwhere the machine is constructed to make a wide fabric, it may be made to make two or more narrower strips at the same time. The sizes of lthe/wires `used may also beA varied and any pre-determined number of twists may be made at each intersection to best accomplish the purpose intended. The meshes may also be made longer or shorter by arranging the coilin mechanisms at diii'erent distances longitu inally and timing their by the adjustment of operation accordingly,

as will the gearing and other mechanisms, be readily understood. i

On one end of the shaft 9'is mounted the bevel-gear 52 which mesheswith the bevelgear 53 mounted 'on the shaft- 54 on which latter' shaft acrank-arm 55' is secured as shown. A connecting-rod or pitman 56 is pivotlly connected to the crank-'arm 55 by means of the bolt 57 as shown. Another cylindricalhole 58 is provided in the connecting-rod 56 for the purpose of shortening` and adjustingl the stroke thereof by connecting it to the crank-arm 55 through another hole 59 as shown, which is slotted in form to allow for radialdjustment. y'W'hen the connecting-rod 56 is connected to the crankarm 55 through the supplementary holes `58 and 59. the stroke of the said rod is sh0rtened and a lesser number of rotations is then made by the direct twisters 37 operated thereby. This means of adjustment is provided so as to vary the number of turns of the wire made by the direct twisters and thereby vary the product in a' predetermined mannertand also for the purpose of exactly adjusting the number of rotations made by these twisters for any particular form of fabric. This adjustment may be made in cooperation with the adjustable connection ofthe pitman 56 to the arm 61 of the toothed-sector 63 which operates the direct twisters. The opposite end of the connecting-rod 56 is provided with an elongated slot 60 in which are adjustably mounted the bearing-blocks 65 adapted to contact with and serve as bearings for the bearing-pin 64 which pin is mounted on an intermediate portion ofthe radius-arm 61 of the toothedsector 63 which latter is pivoted at its lower end as shown at 62. The bearing-blocks 65y justment to the bearing-blocks 65, but it may be readily understood that these bolts may be made as long as desired, to give greater adjustment, if required. On the stubshaft 70 a pinion 69 is mounted, whichv pinion meshes with the toothed-sector 63, and on the sameshaft the gear-wheel 71 is mounted and adapted to meshwith the teeth 51 on the lower edge of one end of the rack-bar 34. The direct twist/ers are rotated by these mechanisms :Mrst in one direction; and then are stationary while a certain amount of lengths of wires are traversed 'through them;.after which they are rotated in the opposite direction; these operationsbeing then repeated in sequence for the formation of the direct twists shown onv the drawings. As the connecting-rod or pitman 56 moves forward one of the bearing-blocks 65 contacts with the bearing-pin 64 and moves the toothed-sector ,63 in one direction, thereby rotating'the direct twisters in acorresponding direction; while during the firstk part of the return movement of the said connecting-rod, the ytoothed-sector remainsstationary, thereby causing the direct twisters to stand without rot-ating for a time; until bythe continuation ofthe return movement of said connecting-rod, the opposite bearing-block 65 contacts with the y. bearingpin 64, whereby the further` return movement of said rod rotates the direct twisters in the opposite direction; whereupon' this sequence of operations is repeated. This,therefore, makes the direct twists of netting of styles and dispositions shown on V`the drawings.

0n one of the outer ends of the twistingdrum-shaft 12 a pulley 7 2 is mounted, which connects. by means of a belt 73, with the anqed belt pulley 74 mounted on the end of t e stub-shaft 7 5 for the purpose of driving the same.V The stub-shaft 75 is provided with a socket to receive and drive the winding-barrel`76, which is temporarily secured thereto in the customary way by a key as shown, and the finished netting is wound on the winding-barrel 76 which is of usual construction. The belt 73 which drives the winding-barrel 76 is provided with a tension-roller 77 revolubly mounted on an arm 78, agtlated by a lever 7 9, provided with the grip-member 80 and the pawl 81 attached thereto. The ratchet-bar 82 coperatfs with the bowl f1 to hold the bolt-roller 77 in po desired; while on the lever 79 is plaie 63 adapted to slidably hold 1 in connection with the ratchet-bar.

supporting-roller 84 is also provided. around part of the circumference of which the netting passes as it travels from n as the twisting-drum to the winding-barrel.

As the roll of finished netting increases in size on the Winding-barrel 76, the belt 73 may be slightly slackened byl the belbtightener or tension-roller 77 and its appurtenances, so that the said belt will slide somewhat over its pulleys while at the same time maintaining the required degree of tautness yin the roll of netting.

Having thus given the foregoing description of the machine and the opera-tion of the various parts, I will now further describe and summarize the operations of manufacture. i

The various wires required for the manufacture of the netting are led to the machine directly from convenient coils or reels in the rear thereof, which, for convenience of illustration, are not shown.' Means may be provided to produce more or less tension in said wires as they are drawn into the machine,

said tensions being varied to best producel the desired results. The intermediate holes 85 are provided for their introduction in cases Where intermediate longitudinal strand-wires are usedythese are led through the central openings 44 in the direct twisters, while the mesh-wires orweft-wires 46 are led through the lateral holes 47 and thence issue from the extremities of the diagonall intermediate tubular fingers 43. The margina'l wires are led through the marginal twisters either concntrically or eccentrically, as desired, as heretofore described. The wires then pass over the twisting-drum 13 on which the fabrication is completed and the finished netting then passes around a portion of the idler-roller 84 and is wound in a roll on the winding-barrel 76. The twisting mechanism of the twisting-drum 13 serves to make the reverse twists and also clamps the wires therein to draw them through the machine with a uniform and continuous motion, and as this is done, the direct twisters 37 and the tubular fingers thereof, coil the weft-Wires around each other and around the intermediate wires and the marginal wires. After one row of these direct coils' is completed across the fence, the direct twisters remain stationary for a time, due to the intermittent movement of their operating mechanisms occasioned by the action of the slotted connecting-rod 56 as heretofore described. While the direct twisters are stationary, the twisting-drum continues to pull the wires forward and when this has been accomplished to the required degree, the direct by their actuating mechanisms, thereby forming the next row of direct twists of the opposite hand. rlfhe direct twisters are then again stationary for a time, as before, w hercupon the sequence of their operations is repeated. .kfter a row of direct twists is made as described, the tubular lingers of the direct twisters remain stationary lfcr a time and hold the wires in the positions shown in Figs. 13 and 1i and are thereby caused to' enter the receiving notches 22 by the revolution of the twisting-drain as it turnscontinuously. The continued revolution of the twisting-drum ca uses thc wires to be advanced and finally seated in the reverse twisters 14 as shown in Fig. 11. The fur- .ther continuation ot' the movement of the twisting-drum causes the rollers 26 oi' the rack-bars to contact with the twistingcani 27, thereby rotating the reverse. twisters 14 inonc direction, which motion is continued as the twisting-drum revolves, so that before the wire` issues from the same, the

rows of the reverse twists 50 are formed. After the wires have issued from the twisting-drum as shown in Fig. 3, the rollers QG on the other ends o-tl the rack-bars contact with the return cam QS and said rackbars are thereby returned to their tirst positions ready for another operation.

rlfhe reverse twisters on the drum 13 are located intermediate of or between the corresponding direct t-wisters, so that the centers of the reverse twisters on the drum are longitudinally opposite the median space between two corresponding direct twisters; the tubes of the direct twisters containing the mesh-wires are inclined as shown, whereby the mesh-wires are twisted around each other, and then, by the stoppage of the direct twisters in the positions shown in Figs. 14 and 11, the-mesh-wires are placed and held in line for direct reception by the receiving-notches 32 and the reverse-twisters 14. By reason of this construction and arrangement no separate shifting mechanism is required to move the weft-wires from one side to the other, as has been custo-many heretofore.

l prefer to stop the rotations o f the direct twisters when the tubular fingers thereof are somewhat above and below a horizontal plane passing through their axes of rotation. When this is done the contiguous tingers of the adjacent twisters are near together, one diagonally above the other, thereby holding one weft-wire above, and the other below said plane and presenting the wires in positions to enter 'the advancing receivingnotches of the twisting-drum and pass thence.

into the narrow slots of the reverse twisters in `pre-determined order, as these slots are K. rahly slightly wider than the diameter oi' one wire and consitherably narrower than ihe combined diameter-of two wire wa; when two or more Wires pass :me ois, the)v must do so in sequence. liv i. means the wires are also seated in each oi the "cverse twisters in a pre-determined older, namely-the weft-wire issuing from the lower tubular linger enters first, then the intermediate strand-wire, if used, and then the weft-wire from the upper tubular linger. B v stopping the tubular tingers in the positions just described and buv timing their stoppage, with due regard to the advancing receiving-notches of the twisting-drum, regular and uniform twists and n'ieshcs are insured. As the twisting-drum .13 revolves it. carries with it the .fabric in process of formation, the final twisting of which completed, before it leaves the dri-.in as shown in Fig. 3. After leaving the drum the. fabric passes behind the hitler-roller Si" and is wound in a roll on the whirling-barrel 7h as heretofore described.

For convenience oi illustration Aand description l have shown the machine with the direct twisters side by side with their rotation axes parallel and in a horizontal plane, and with the axis of the twisting-drum located horizontally, but I wish it understood that itl/lese.arrangements and those of the other parts, may be modified and that the relative or absolute positions of the various mechanisms may be varied, without departing from the spirit of my invention. To facilitate clear illustration, the marginal strand-wires or selvage wires are shown as single wires, but these may be composed of two or more wires previously twisted into cable form, if desired. l

Although I have described and illustrated my invention in considerable detail, Ido not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are embraced within the scope of my invention, or as pointed out. in the claims.
