SPECIFICATION forming part of Letters Patent No. 483,969, dated October 4, 1892.

Application filed October 22, 1891. Serial No. 409.682. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN ScARLEs, of Clinton, county of WVorcester, State of Massachusetts, have invented an Improvement in Wire-Netting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to so improve machines for the production of wirenetting that a longitudinal strengtheningstrand may be introduced and run through each mesh, if desired. The machine described in United States Patent No. 433,633, granted to me August 5, 1890, shows means for introducing such longitudinal strand into a particular line of meshes, and a strand might be introduced in any one line of meshes, but not in all. The machine described in the said patent had the faces of its twisting-segments out partially away for the passage of a strand-wire to the center of motion of the segments in only one direction, the said segments being each provided with a lug to contact with the face of an opposite segment, the said lugs being a necessity to enable the segments to be kept seated in their hearings in the sliding carriages. To enable strand-wires to interchange with the mesh-wires from right to left, and vice versa, so as to put a strand-wire in each line of meshes, it is necessary to provide a clear open space for the strand-wires between the faces of the twisting-segments, and to enable this to be done I have devised means to loosely connect the twisting-segments with the sliding carriages and yet permit the said segments to pass readily from one to the other carriage, as required. The means of connection which I prefer is somesort of a track to co-operate with a shoe, one being on the carriage and the other on the segment.

In ordinary wire-netting machines, and in fact in all such machines known to me, the mesh-wires are delivered from holes in the tops of the twisting-segments. In practice tltixe wires are subjected to very considerable s aimand drag on the tops of the segments, thus rapidly cntting and wearing away the said openings. To obviate this rapid wear on the segments, I have provided them with sheaves or rolls, over which the wires may travel freely without friction, the said sheaves when worn being readily renewed. The size of the mesh in the direction of the length of the netting is controlled by the speed of the mesh-roll, and when the speed is slow the meshes are'wider across the not than in the length thereof. The sheaves referred to should, for the best results, be free to not only rotate about their own horizontal axes, but also to turn about vertical pivots, thus preventing any liability of the wire slipping laterally off the sheave under great strain. To obviate this, the axis of the sheave maybe mounted on a collar or sleeve surrounding the wire-passage, said collar being free to turn about said wirepassage by the action or strain of the wire on the sheave.

The improvements referred to may be incorporated in a machine such as represented in United States Patents Nos. 433,633 and 380,664, wherein the mesh-wires are twisted one about the other in usual manner, or the mesh-wires may be twisted together, as represented in United States Patent No. 387,739, and I have herein chosen to illustrate my said improvements as applied toa machine adapted to twist the wires as provided for in the latter patent.

In the Patent No. 387,739, while the reverse twist was being put in the wires were held between long jaws having pins extended between the wires, the said pins preventing any possibility of the netting being moved or fed along, and consequently the rotation of the mesh-roll was suspended while the so-called reverse twist was taking place, thus materially lessening the productive capacity of the machine, which is a serious fault when it is remembered that to enable wire fencing to -be largely used it must be made as economi- I have therefore devised cally as possible. means whereby the pins mentioned are dispensed with, yet the strands twisted together in one direction are firmly clamped while the reverse twist is being put in, and the meshroll continues to work during the reverse twisting. Instead of the pins I employ clamps capable of moving with the wire-netting in the direction of the feed of the netting by the mesh-roll and at a speed determined by the speed of said roll. may be composed of rolls, and these rolls may be mounted on levers or fingers adapted to turn about a fulcrum, such movement being at times desired-as, for instance, when a joint in the wire comes between the clamprolls. For very heavy wire-netting I may, in place ofthe clamp-rolls, substitute clampdogs, as will be described. I have devised novel means for actuating the bars, in which are mounted the levers or fingers containing the clamping-surfaces.

In the Patent No. 387,739 the rack-bar for rotating the twisting-segments derived its rotation from a crank and pitman, the crank rotating continuously; but in this present invention in order to accommodate the peculiar clamping mechanism and continuous rotation of the mesh-roll I have devised means whereby the pitman for actuating the rack-bar is driven from a radius-bar moved by a cam, as will be described.

Figure 1 in front elevation represents asufficient portion of a wire-netting machine to enable my invention to be understood, some parts of the machine being partially broken away to show other parts at the rear, the mesh wires and strand-wires being but partially shown to thus obviate confusion of lines in the drawings, the reels carrying the Wires being omitted, except at the center of the machine, it being expected that in practice the reels will extend from one to the other end of the machine and that the machine will be supplied from one to its other end with wires,

as represented at the left in Fig. 1. Fig. 2 is a left-hand end elevation of the machine shown in Fig. 1, the reels being omitted. Fig. 3 is a section on the line :0, Fig. 1, it being supposed,

' however, that the machine is fully supplied with twisting-segments, especially in the said line. Fig. 4: is a detail in plan view, broken out at different places, of carriages, rack-bars, segments, clamps, &c., to be referred to; Figs. 5, 5, and 5, three details showing different positions for the parts instrumental in actuating the wire-clamping devices which are effective during the reverse twisting operation. Fig. 6 is a sectional detail showing one of the clamping-surfaces. Fig. 7 is a modified form of clamping-surface; Fig. 7, a section on the line 2 2, Fig. 5. Fig. 8 is an enlarged sectional detail taken through a pair of segments to show the tracks which retain the segments upon the carriages and also the swiveling features of the sheaves. Fig. 9 shows an inner side view of one of the segments shown in Fig. 8. Fig. 10 is a top view of the segments shown in Fig. 8. Fig. 11 is a top view of the carriages to illustrate their segment-tracks. Figs. 12 and 13 are respectively a section and top view of segments wherein the rolls do not rotate about the centers of the mesh-wires. Figs. 14 and 15 show pieces of netting such as maybe made on the machine to be described, and Fig. 16 shows a For fine wires the clamp piece of netting such as may be made by omitting the strand-wires.

Referring to the drawings, the framework A, the rolls f f" f, the reels 103 and 104: for the mesh-wires 101 102, and the strand-wire 205, coming from a like reel, (shown partially in Fig. 3,) the mesh-roll B, the roll 42, having the gear 40 engaged by the worm 39 on the sleeve 38, loose on the shaft A the said sleeve having a pinion 37, the beveled gear A engaged by the beveled gear A fast on the shaft A having a belt-pulley A adapted to be rotated by a belt A the shaft B having fast upon it a pinion B engaged by a gear B fast on the shaft A the cams O 0 fast on the shaft A (see Figs. 2 and 4) and adapted to act upon roller-studs carried by the sliding carriages E D to reciprocate them, the rack-bar m, contained within the sliding carriage D, the gear 44 on the shaft 42, it engaging the pinion 45 on the shaft of the meshroll B, (shown in Fig. 1 as provided with pegs for but a portion of its length,) the rock-shaft 116, having the depending arms 115, swiveljointed at 115 to the jaw-bar 107, having a tongue-and-groove connection with the surface of the carriage D, upon which it is mounted, the said tongue-and-groove connection being shown in Fig. 1, the arm 117, fast on the rock-shaft 116 and provided with a weight 119, and the means for actuating the take-up roll are and may be all substantially as in the said Patent No. 387,739.

The gear 37, loose on the shaft A and com- 1 mon to the said Patent No. 387,739, in practice was in said patent engaged and rotated intermittingly by a mutilated gear; but herein the said gear 37 is engaged by a gear it, fast on the shaft B so that thesleeve 38 has a continuous motion, the worm 39, in engagement with the worm-gear 40 on the shaft 42, effecting a continuous rotation of the meshroll. Herein the gear B common to the said patent, is made to engage and rotate a gear 'n, mounted on a shaft, or it may be a stud 72 the said gear having-a cam-groove n represented as having four throws, two on each half, the said groove receiving a proper roller or other stud a, connected with a radius-bar n shown as fast on a suitable shaft or stud a, mounted in suitable bearings m the upper end of' the said radius-bar being slotted and having adjustably connected to it by a bolt a one end of a connecting-rod n", the opposite end of which is adj ustably connected with an arm 11 having its fulcrum on a stud-bolt n (shown best in Fig. 3,) held in a dependof the wire with the segments at the open ends of the passages. These rolls, located, as represented, beyond or outside the open ends of the delivery-passages for the mesh-wires, are also of very great value when certain classes of wires are being used,for by passing the wires once around the rolls or sheaves, the latter act to swage, as it is called, or straighten the wires, thus making a netting very smooth and uniform. The rolls are also of very great utility, for they enable galvanized wire to be worked successfully, as they obviate wearing the galvanized coating. It is not intended, however, to limit this invention to the particular shape of the sheave or delivery-roll or to the mounting of the delivery-rolls so that they will swivel, for the said rolls without the swiveling feature are avery great benefit.

I have shown in the modification, Figs. 12 and 13, the rolls as having their journals mounted in fixed bearings upon the upper ends of the twisting-segments.

It is not intended to limit the use of the tracks for the segments, or the delivery-rolls, or the two racks to a machine for uniting wires bya reverse twist; but the same may beused when the mesh-wires come from cop-tubes, as represented in United States Patent No. 433,633. I have, however, herein shown the mesh-wires as united by reverse twisting, and the mesh-wires are so twisted reversely at each juncture abouta strand-wire; but should I desire I may leave out one or more strand- Wires 205 at any desired point.

- In the patent referred to, after the first part of the twist in a mesh had been put in a pin 7 carried by a clamp-jaw entered between the mesh-wires, and the twisting-segments were reversed in their motion, putting in the reverse twist; but, as stated, when the pin was in working position the motion of the meshroll had to be suspended during the reverse twist to enable the strands to be held firmly when the reverse twist was to be put into the mesh -wire, and to not necessitate stopping the rotation of the mesh-r0111 have provided movable clamping-surfaces, which, when the Wire detail, Fig. 2

is of smaller diameter or not very heavy, may be a pair of rolls b b, one having a groove and the other a projection to fit the groove, as best represented in Fig. 4 and in the enlarged The rolls or movable clamping-surfaces b are represented as mounted upon levers or fingers a pivoted at 00 on the jaw 107, adapted to be moved forward and backward or toward and from the wires being twisted, as in United States Patent No. 387,739, referred to. The rolls b are represented as mounted on fingers or levers a pivoted on suitable ears or stands erected on the carriage E. The jaw 107 is moved forward to clamp the mesh-wires between the rolls b and b after the said wires have been twisted in one direction, the rolls or clamps engaging and holding the said Wires as the reverse twist is being commenced.

The jaw-bar 107 (see Figs. 4 and 5) at its outer edge has, as represented, two lugs a, on which are pivoted levers a, each having, as shown, two antifriction-rolls a and a springs a and a acting on said levers to normally keep them in the central position Fig. 4, but permitting them to turn about their pivots on the lugs a to enable the said rollers to enter notches in a push-bar at, attached to and slid ing in unison with the rack m and the auxiliary slide G, said bar, as herein shown, having six cam-recesses.

The mesh-wires need to be clamped only while the second or reverse half of the twist is being effected therein, and the surfaces between which the wires are at such time held must hold the wire with sufficient force to prevent the first part of the twist from being untwisted, and, as herein provided for, the said clamping-surface must also be able to move in the direction of the travel of the netting under the action of the mesh-roll.

In the form in which my invention is here in embodied I have devised means (the cam m to divide each complete right and left movement of the rack into two steps, and be tween the first and second steps of the rack bar the carriages are moved to shift or redistribute the twisting-segments, each pair of said segments in each operative position being rotated first in one and then in an opposite direction to put in the first and then the second part of the mesh-twist, the second part or half being always the reverse of the first part or half; but the last half of each meshtwist is always in the same direction as the first half of the next mesh-twist to be made in the direction of the length of the netting. After the first part of each twist has been put in the jaw-bar 107 on the carriage D is moved toward the jaw-bar b fixed on the carriage E, the clamping-surfaces b and 19 (shown as rolls) being used if the wire being twisted is not very stiff, the said wire being firmly clamped while the second part of the meshtwist is put in in a direction opposite the first half, the roll-like surfaces turning as the net is moved by the mesh-roll, and if during this time a knot caused by joining two ends of the wires should come between the said rolls or surfaces the pivoted levers carrying the said rolls or surfaces will rise, the springs c and 0 (shown in Figs. 3 and 6) permitting them to rise and throwing them down quickly on the passage of the knot. If the wire is quite stiff, the rolls b and b mounted on studs held in ears of the levers a a are removed, and in their place I substitute the modified form of clamp 12 (shown in Fig. 7,) it having a stud b to enter a hole (shown by dotted lines, Fig. 6) in the clamp-carrying 1e ver, one such clamp for each lever, the said clamps engaging the wires snugly by their V- shaped mouthsand rising with the net, they being disengaged from the wire when the 107 is retracted by the weight 119.

Referring to Figs. 4 and 5, showing the le- IIO arm m (shown best in Fig. 8,) which enters substantially and snugly a slot in the auxiliary slide G. The aukiliary slide has stop-screws m m, which may be'turned in or out more or less, according to the amount of lost motion desired between the arm n and the said stop screws, and as the radius-bar n is vibrated by the cam the arm n is also vibrated, and by its contact with the stop-screws moves'the auxiliary slide more or less, taking the rackbar min unison with it, so that the latter, in engagement with the teeth of the twistingsegments p, rotate the latter. The segments are substantially alike, and each has a series of teeth to be engaged by the said rack-bar.

Herein I have added to the machine a second rack-bar and have marked the same 0'', it being made operative through the rack-bar m and an intermediate pinion r on a suit able stud 4*, (shown in Fig. 1 by breaking away the front carriage and rack-bar m.) the said stud being held in a fixed part 1' of the frame.

Herein each carriageE D is provided about the semicircular bearings for the necks of the twisting-segments with a track, as D, (represented best in Fig. 11,) said tracks receiving segmental shoes D forming parts of the twisting-segments, the construction of the tracks or guides being such that the faces of the twisting-segments are kept from contact or separated sufficiently to enable the said segments, when their faces are parallel with the inner faces of the sliding carriages and the carriages are being shifted to the right or left, to pass over the strand-wires. WVhen the said twistingsegments are rotated to travel from one into the other carriage, the shoes D will follow on the tracks D from one to the other carriage, and during this movement'the teeth of the twisting-segments will remain properly in mesh with the teeth of the rack-bars employed to actuate them.

It is not intended to limit this invention to the exact means herein shown to retain these twisting-segments in operative position with relation to the carriages, so that they may be actuated by the racks, and instead of the partieular shoes and tracks shown many other equivalent contrivances might be employedthat is to say, it is immaterial whether the projection constituting the shoe come from the segment and enter the carriage or whether the projection be upon the carriage and enter a groove in the segment-the gist of my invention in this particular including any equivalent means or devices which will retain the twisting-segments in position upon the carriages and with the teeth of the segments in engagement with the racks, and yet leave an open space between the segments to enable them to pass over a strand-wire at either stroke of the carriages when desired.

In this my invention one rack in engagement with one segment starts and rotates that segment, causing its shoe to pass to the track of the opposite carriage,and then a second as the other rack engages it.

rack engages the said segment and completes its movement in that direction, each rack working without interference from the other, one rack leaving the teeth of a segment just This is an important feature of my invention.

To obviate the enlargement of the meshwires of the upper ends or mouths of the passages in the twisting-segments through which the mesh-wires are delivered,I have provided each segment with a sheave or rolls and, for the best results, I have mounted the axes s of the said sheaves (shown as sleeves) in ears of a swiveling collar or sleeve 8 so applied to the segments as to be free to rotate about the mesh-wires which are being delivered therefrom.

In this presentinstance of my invention, as shown in Fig. 8, the lower ends of the sleeves referred to are made conical and enter correspondingly-shaped openings in cap-plates attached to the top of the segments in suitable manner, the said cap-plates being made in halves, as best represented in Fig. 10, so that they may readily fit the conical shank of the sleeve. By the employment of these delivery sheaves or rolls the mesh-wires are delivered without friction upon the twisting-segments, and the power required to run the machine is greatly lessened, and if a sheave becomes worn a new one may be readily substituted. These sheaves are very essential, the more essential as the wire used increases in size, and by their employment very great saving in cost of segments is made. The swiveling feature of the segment is very desirable, especially when the speed of the mesh-rollis slow and the mesh is narrower in the direction of its length than of its width,or when substantially-square meshing is being made, as at such times the sheaves by the rotation of the sleeves are enabled to deliver the wire straight, and the strain upon the wire never causes the same to leave the grooves of the sheaves.

In practice a machine having its twistingsegments provided with rolls, as described, may be used to make netting from wires of different diameters, and a wire of any diameter within the capacity of the mouth of the segment may be used at any time, which could not be done on a machine having twisting-segments of the usual kind, for the reason that the strain on the Wire led out through the mouth of the segment of usual form soon causes the wire to cut a groove a-little larger than itself in the segment, and a segment so cut by one wire, cannot afterward be used successfully for a wire of another diameter. The employment of the rolls therefore makes it practicable on one and the same machine to produce netting from wires of any desired diameter. then the rolls are used, the se ments are not cut or grooved by the wire; but the rolls when out may be easily and cheaply renewed. The peripheries of the rolls or sheaves are so located with relation to the mesh-wire passages as to prevent the contact IIO 'vers a. and bar at, where both rolls a and 0.

During the first part of the movement of the said bar the racks m and '1" will rotate the segments and the rolls a will enter the notches tof the said bar, as shown in Fig. 5. Next the movement of the bar a is reversed or it is moved to the right, and during this movement one of the shoulders or sides of the said notches by acting on the rolls a (shown in Fig. 5*) causes the jaw-bar 107 to be pushed forward into clamping position, causing the clamps referred to to clamp the wire snugly between them, and while the shoulder continues to hold the clamps closed on the wire the reverse turn of the segments takes place through the action of the said bars then moving to the right. After the shoulders of the bar of act, as described, to move the clamping-bar 107 forward, the rolls a in the continued movement of the bar a ride on the surface If, said surface being a straight part of the bar, and finally the rolls a come opposite the notches i and were it not for. the lugs a the rolls a would fully enter the said notches and the incline at one side thereof would immediately act in the farther movement of the bar a to the right to again cause the jaws to clamp the wire; but these lugs as the clamping-bar 107 recedes for aslight distance, as represented, say, by the dotted lines y andz, Figs. 3 and 5, meet the stop-plates t, and inasmuch as the clamp-bar normally acted upon by the weight 119 cannot move back and take with it the rolls, it results that the rolls are relieved by the lugs a from the dutyof holding the clamp-bar 107 forward, and-the levers a, carrying the rolls a a are free to turn on their pivots and resume the positions shown in Fig. 1. This done, the carriages are moved to the right to shift the segments and the rack-bars are moved in the same direction to twist the segments, and while the twisting is taking place the bar a is also moved farther to the right until the roll a enters the notch (See Fig. 5.) This done, the rack-bar is now started to the left to thus enable a shoulder of the said bar a to act on the roll a as described, of the roll a and again cause the clamping-bar to be moved forward to clamp the wires while the reverse twist is being put in. This action is repeated with the formation of each transverse row of meshes.
