' fencing which shall have two sets of stay or brace wires,

the stays of one set having their ends coiled about or otherwise connected to the strand wires or cables and the other set ofstay wires being coiled about or otherwise connected to the first set of stay wires. This idea of two sets of stay-wires, one only of which is connected direct to the strand wires or cables, constitutes one of the main features of the present invention which. con-- sists of the parts and the construction and combination of parts as hereinafter more fully described and claimed,

Figure 1 is a diagrammatic plan view showing the various steps incidentto the positioning and tying of the stay wires. Fig. 2 is a plan view of the machine' Fig. 3 is a side elevation of the same. Fig. 4 isan elevation somewhat similar to that of Fig. 3, showing certain parts in section and taken on line X X of Fig. 2. Fig. 5 is a cross section on line Y-Y of Fig. 4, with the gears shown in full'elevation. Fig.- 6 is a detail show-- ing in elevation on an enlarged scale the tyingmechanisms of Fig. 3. Figs. 7-8 & 9 are side views of the Wrapping means for the second set of stay wires, with these means shown in successive positions. Figs. 10- ll & 12 are corresponding sectionsof the same means.

The general character 'of the fence which my machine is designed to make is clearly indicated in Fig. 1, wherein A represents 'a series of longitudinal strand wires or cables suitably spaced apart; successive pairs of these strands being connected together from left to right by the short cross wires or stay wires 2; these latter in turn being connected by other cross or stayjwires '3. In that figure which is partially diagrammatic the The distance apart of the several strands and stays tied set, advancing the strands, and crimping the strands as shown at 4.

determines the mesh of the fence; and the mesh like the height of the fence, the number of wires, thesize of the wires used, etc., depends onthe particular use or purpose for which the particular fence is intended.

A characteristic of my machine is that the stay wires 23 are all cut to length before being fed into the machine as distinguished from feeding the stay-'wire-material from a coil and cutting it tov lengths in the machine.

5 represents the frame of the machine; 6 are friction rollers or tension rollers arranged in pairs and between reels or spools and by which they are held taut during the subsequent tying operations. Each pair of rollers which the several strand wires are drawn from the 6 is adjustableto cause the rolls to grip' with greater or less pressure on their respective strands. As shown the lower rollers are vertically adjustable to and from their respective upper rollers by means of the-set screws 7 and the movable boxes 8 which support the shafts of the lower rollers.

From the'rollersfi the .strands pass axially through the hollow spindles 9 which slidein and turn with and are coaxialwith the hollow worm gears 19; the latter being suitably journaled in the frame and being driven intermittently in unison by the gears 11 on shaft 12. Each spindle 9 carries a coiling finger or projection 13 arranged substantially parallel with and movable in a circle about the contained strand wire when the spindle is rotated, for the purpose of tying one end of a cross or stay wire 2. The strand wires are assumed to travel intermittently in the direction of the arrow Figs. 4 61. The stay wires 2-3 which as before stated are preferably cut to length before being fed to the machine are delivered at proper intervals on the strand wires from the respective hoppers 14 15.,

The hoppers 14 are adapted to drop their stay wires 2 onto the strand wires or cables A in such manner that one stay wire 2 will rest on the first and second strands from the left, another stay wire 2 will rest on the 3rd. and 4th. stay wires from the left, and so on, each stay wire 2 coming down upon a corresponding pair of strand wiresor cables, except the last stay wire 2 which overlaps the next to the last stay wire and has its inner end supported in common with the next to the last stay This iswhere an beyond a corresponding cable to admit of the proper tie or knot being made, the spindles 9 are reciprocated to project their fingers l3 forward and over the corresponding ends of; the stay wires .2. As the spindles 9 are made to turn in unison with the worms 10, the setting in motion of the worms 10 will wrap the projecting ends of the stay wires 2 about the cables A and form the knot shown at a in Fig. 6.

The forward projection of the spindles 9 into operative position and their gradual retraction during the wrapping process is effected by the following means: lly reference to Fig. 3, l6 is the main drive shaft adapted to be driven constantly from any suitable source of power; This shalt carries a gear meshing a larger gear 17 on a countershaft l8; the latter is provided with a cam .lfl adapted at each revolution of shaft 18 to rock an arm 20 fixed to a rock shaft 2| the latter has a series of forked projections 22, each to engage a corresponding spindle. A spring 23 acts on arm 20 to tend to throw all the spindles forward so that their coiling fingers 13 will be underneath hoppers 14 and over the ends of the stay wires 2 deposited from hoppers 14. "he timing of the parts however, is such, that these fingers will be projected only into such position beneath the hoppers at the moment subsequent to the deposit of the stay wires and while the strand wires are stationary and immediately prior to the setting inrotation of the spindles to tie these stay wires. Thus in Fig. 3 the roller on arm 20 is. shown to have just passed over the highest point of cam 19, which would indicate that the fingers 13 are all thrust forward in a position shown in Fig. 4, and that the coiling operation is about to begin. This operation is effected through the medium of the mutilated gear 24 engaging a smaller gear 25 on shaft 12. By the turning of the shaft 12 and correspondingly its several gears 11 the various spiral gears 10 are set in motion, which in turn causes the fingers 13 to wrap the ends of the stay wires 2 about the strands A in the desired fashion.

As readily understood the spindles are arranged in pairs corresponding with the pairs of cables on which a stay wire 2 is deposited with the exception of the last spindle. The spindles of each pair are adapted to be rotated in opposite directions while the end spindle where there is an odd number of cables runs in the same direction with the next succeeding spindle. Of course if it is desired to make a fence with an even number of strands, the last spindle, or that one to the extreme right to Fig. 1, may be omitted; and, if fencing of a variety of sizes or widths having an odd number of strands is to be made, the spiral gears for driving the twisting, spindles can easily be changed so as to run thelast spindle in the series in a proper direction.

At the same moment that the shaft 12 is set in operation the cam 19 begins to act on the roller on arm 20 to gradually retract the several spindles consistently with the wrapping of the ends of the wires; this gradual retraction of the fingers and spindles being for the purpose of preventing the latter from cutting or severing the stay wires. This wrapping or tying of the stay wires 2 to the cables is effected in approximately a half revolution of shaft 18; during the remainder of the revolution the gear 25 and shaft 12 and the several gears 10 remain stationary, and the spindles and fingers 13 are retracted from beneath the hoppers 14. The strands A may now all be advanced in unison to carry the tied stays 2 up against the stays 3 which have been deposited from the hoppers 15 upon the strands. By a succeeding movement of the strands the tied stays 2 and the untied stays 3 are carried forward to the slotted rotatable jaw members 26 by which the ends of the stays 3 are wrapped around the previously knotted stays 2; The spindles 9 by which the first set of stays 2 are tied to the strands A have their axes parallel with the strands. The wrapping jaws 26 have their axes at right angles to the strands and parallel with the stays 2.

"he hoppers 15 by which the stays 3 are deposited on the strands are arranged alternately with the hoppers l4 as shown in Fig. 2, and they are designed to deposit their stays on the second and thirdffonrth and fifth strands, and so on, thus bridging and connecting those strands which Were not connected by the stays 2.

The wrapping jaws 26 are each shown substantially in the form of a gear wheel having a radial slot 27. The width of the slot 27 is just sufficient to admit a stay wire, and is less than twice the width of any stay Wire. The depth of the slot is a trifle greater than the length of a radius of the gear 26, so that when the stays are in position for knotting in the member 26, the already knotted stay 2 will be approximately coaxial with the jaw member 26 while the stay 3 is slightly eccentric to the same, so that when the jaws are rotated, the free end of the stay 3 will be coiled about the stay 2 in the desired manner. These several gear wheels are intermittently rotatable and the slots in each are adapted to be brought into coincidence with the plane of the strands A to permit of the proper entry, and subsequently of the proper exit, of the stays 2-3 These jaw members 26 are shown in Figs. 1011 & 12 as having annular grooves to receive coriesponding annular bearings 28'on which the gears 26 turn.

The proper revolution of the knotting devices 26 is effected synchronously with the various other movements of the machine by the following means: A shaft 29 is arranged parallel with the axial line of the members 26 and carries a series of gears 30 engaging the gear teeth on the respective members 26. The end of the shaft 29 has a gear 30 which is engageable intermittently and successively by the toothed segments 31-- 32, Fig. 4, of gear 33 onshaft 34, which latter is driven constantly from shaft 16.

By reference to Fig. 4, it will be observed that the slot 27 of the jaw 26 is turned toward the spindles, and that a stay 3 which has been pushed up against a previously tied stay 2 has been moved'into position in the jaws 26. At that moment the gear 33 revolving in the direction of the arrow, the toothed portion 31 of the gear engages the gear 30 on shaft 29 to set the latter and the several jaws 26 in motion. This rotation of the jaws 26 acts in the manner indicated in Figs. 7 to 12 inclusive to wrap the ends of the stays 3 about the stays 2. This wrapping or knotting operation is completed by the time'the blank portion 35 of the gear 33 comes around to the gear 30 on the shaft 29. While the blank portion 35 is passing the gear 30, the latter remains stationary but with the slot 27 pointing toward the rear of the machine or in the direction opposite to that indicated in Fig. 4; this allows for the stays and the completed portion of the fencing to pass on. A continued movement of the gear 33 brings the teeth 32 into mesh with the gear 30 which results in a half turn being given to all the jaw members 26, so as to bring the slots 27 into position shown in Fig. 4. ready for the next operation. There is another blank space 36 on gear 33 between the toothed segments 32-31 and while the gear33is traversing this space, the jaw mcme ing part.

the jaws for tying. Appropriate stopv mechanism as .the plate 37 fixed to'gear' 3 and engaging corresponding concaved parts 38 on shaft 29 are employed to lock the members 26 against movement during that time when the gear 30 is out of engagement with eithepof the segments31 32. Similar stop mechanisms, not necessary to be shown, are employed throughout the machine where one part has an intermittent rotative.

movement with respect to another constantly rotat- The stay wires 23 have previously been cut todhe proper length and delivered into respective magazines 3839 corresponding to the feed hoppers 14-15., The

' stay wires are fed singly fromthe magazine to the hoppers by means'of the rotating cylinders or feeders 40 having longitudinal grooves 41 corresponding in length and depth to a stay wire. The number of these groeves 41 and the step by step rotative movement of the feeders 40 are appropriate to the step by step move.-

ment, of the cables A.

As seen in Fig. 3 the feeders 40 are geared together as shown at 42 and a stepby step movement is given to the feeders inunison by means of an' arm 43 fulcrumed loose on the shaft of one of the feeders 40 and having a pawl 44 to engage one of the gears 42; a link 45 connects arm 43 with a spring-pressed-arm 46, which is actuated intermittently by a cam 4701i shaft 12. l A

The intermittent feed or step by step motion of the strands or cables, and the simultaneous crimping of the I strands or cables is done by means of the drum 48 with its series of sliding gripper bars 49 carrying the projections 50 which c'o-act with the concaved fixed projections-5l onthe drum. This drum 48 extends across the machine and has a series of bars arranged on its periphery and extending lengthwise'of the drum and slidable in suitable guides as shown in Fig. 4. The' distance apart of the bars correspond to the distance between the crimps 4 of the fencing. The bars 49 each carry a roller 52 at one endadapted to run on a fixed annular cam 53 arranged concentric with the drum,

and by which the bars are pushed in to cause the cables'to as gripped. The bars are retracted by the natural springiuess of the cables. e

The bosses 51 are disposed relative to the respective projections50 and the positions of these several bosses and projections or jaw-members 50-51 correspond to the distance-apart of the several cables. The adjacent face oieach boss is concaved as shown at 54 corresponding with the convexity of the adjacent cooperating gripper part 50. When the bars'are drawn out so as to separate the parts 59-51, the strands'are easily engaged or removed from between these parts 50 -51. As the drum is rotated to reciprocate the bars 49 and grip the cables between the parts 50-51, the several cables are drawn forward, and at the same moment they are given a crimp or kink, as indicated at 4 Fig.-

wire fencing, is advantageous in that it allows for the expansion and contraction of the fence and permits the fence to be properly stretched and maintained taut under all climatic conditions.

The length and pitch of the cam 53 aresuch, and the number-of bars 49 is great enough, to insure a sure grippage by one or more of the bars all of. the time on .1

the cables. The fence is carried a considerable dis tance around the drum before the bars are retracted to release the cables, the fence then passes around the idle roller 56 and thence onto the receiving reel 57*,

thelatter being revolved in unison'with thedrum 48 by suitable means as shown at 57. A step by step motion is given to the drum coordinate with the other moving parts of the apparatus by any suitable means. As shown in Fig 3, the shaft 34 has a mutilated gear 58 to engage a gear 59 on a countershaft 60.' Gear 59 i meshes, a corresponding gear 61 on the shaft of drum 48. A stop-plate 62 on shaft 34 is adapted to engagea corresponding stop member 63 on shaft 60 to hold the drum stationary during the period of rest of the gear 59. lt isunderstood that all the various movingparts of the machine are so timed, thatevery part willperiorm l its required function in the proper manner and with due respect for every other part.

The operation of the, apparatus is The several cables A according to the number of de-j I sired strands in the fence, are passed between theten-" sion rollers 6 and through the' several spindles 9, thence v around the drum 48, idler 56 and connected with the reel 57. The magazines 38-39 being filled with stay wires, the machine is set in operation. Thefeeders' 40 ofthe magazine are adapted to be revolved and deposit each a stay onto the cables, when the latter "are I at rest. The spindles 9 arethen moved forward to allow the fingers 13 to overlap the ends of the stays 2 Next, the several pairs of-spiral gears 10 are set in motion in opposite directions to knot the ends ofithe" stays 2 around the cables A; the spindlesbeing gradually retracted during the knotting operation. During the successive forward movements of the cables, the

knotted stays 2 and the unknotted stays 3 are carried forward into the radial slots 27 of the wrapping jaws 26. The cables then come to rest, and at the. proper moment the gear segment 31 acts on the gear 30 to re volve the jaws 26 and tie the stays 3 to the stays 2. When this knotting operation is completed, the slots 27 are left in open position toward the drum 47; on the next forward movement of the .cables A and while the blank space 37 on gear 33 is passing gear 39, the stays are withdrawn from the slots in'jaws26. The cables then come to rest and the segment 32 on gear 33. en-

stays into position in the slots in the jaws 26. The.

operation of crimping the stays33 is then repeated. As before described the step by step feed of thecables is done by an intermittent rotation of the drum 48 and the sliding in and out of the bars 49 to cause the projections 50 to co-act with the bosses '51 in gripping the cables. j i i I Having thus described my invention, 'what I claim and desire to secure by Letters Patent, is
