GEORGE W. WHITTINGTON, OF INDIANAPOLIS, INDIANA.

MACHINE FOR WEAVKING DIAMOND-MESH FENCING.

SPECIFICATION forming part of Letters Patent No. 768,102, dated August 23, 1904. Application filed Qctober 25, 1902. Renewed July 16, 1904. Serial No. 216,777. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. WI-IITTING- TON, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for WVeaving Diamond-Mesh Fencing, of which the following is a specification.

This invention relates to improvements in machines for weaving fences having horizontal wires which are connected by intermediate wires woven to form a diamond-shape mesh between the said horizontal wires.

I accomplish the objects of the invention by the mechanism illustrated in the accompav nying drawings, in which Figure 1 is a plan view of my. invention; Fig.2, a vertical section, central longitudinal, of Fig. 1; Fig. 3, a right side elevation of the main machine; Fig. 4, an elevation of.

the opposite or left side of the main body of the machine; Fig. 5, a rear elevation of the cross-bar which supports the wire-twisters, the twisters and retaining-caps being in place on said bars and portions being in vertical section; Fig. 6, a like view of same cross-bar and twisters, showing in addition the mechanism for shifting the reciprocating portions of the twisting device; Fig. 7, a horizontal section on the dotted line 7 7 of Fig. 6; Fig.

Fig. 16 is a detail in vertical section of Fig. 15 on the dotted line 16 16 of said figure, and Fig. -17 is a view in side elevation of the product of the machine.

Like characters of reference indicate like parts throughout the several views of the drawings.

The wires 1, from which the horizontal strands of the fence are formed, are wound on spools 2 (see Figs. 1 and 2) of any usual and well-known construction. are supported on suitable standards 3.

It will be noted on examination of Fig. 17 that the horizontal strands are closest together at the lower part of the fence, that the middle strands are farther apart than thelower strands, and that the strands of the upper third of the fence are farthest apart-of all. The

These spools I horizontal strands and diagonal wires connecting said horizontal strands, making adiamond-shaped pattern, and the machine illustrated is for the manufacture of such a fence.

A represents the'loomor body of the machine .where theweaving is done. Between said body and the spools 2 are the horizontally-mounted spools 4, which furnish the wires 5 for the cross-strands of the fence. The spools 4 number one less than the number' of horizontal strands. They are placed in two horizontal rows between'the machine A and the standards 3, with their axes converging toward the said machine, asshown in Fig. 1. In the operation oftwisting the diagonal wires with the horizontal ones all of the twists in a given line transversely of the fence are made simultaneously. In said lines it will be noted thateach alternate-horizontal wire has no diagonal wire twisted with it, and

in a row having twists with the outside horizontalvwires there will be seven twists, requiring seven cross-w1res. These Wlll be supplied from seven spools in the first row or row 'of spools nearest to the machine.

row of spools will be six in number and will The outer supply the cross-wires for the transverse row of twists in the fence, having but. six twists in it. are carried at proper intervals fromone horizontal wire to another and by which the several wires to be woven into the fence are kept The means by which the cross-wires from entanglement before reaching the wiretwisters form the essence of this invention. The reeling up of the finished product and the means for insuring a uniform progress of the wires through the twisters being the same as shown and described in a former application for patent made by me and filed at the Patent Office on the 25th day of July, 1902, Serial No. 117,028, will not be described.

6 represents a shaft mounted in suitable boxes on the frame A. It has the pulley 7, to which power is applied through belt 8.

9 is a shaft parallel with shaft 6 and having the spur gear-wheel 10, (see Fig. 3,) the cogs of which engage those of the pinion 11 on the shaft 6. The outer side of the wheel has the bevel-cogs 12, which extend less than halfway around the wheel on the side of the latter. These teeth engage the teeth of a bevelpinion 14 on the upper end of a shaft 15. A rotation of shaft is obtained during less than half of each revolution of the wheel 10. Accidental rotation of shaft 15 is prevented by the flat-sided wing extension 16 from the inner side of wheel 14 by the contact of the latter with the fiat-sided track 17, projecting in the path of wing 16. This track ends opposite the beginnings of the teeth 12. The

shaft 15 has the bevel-wheel 18, which engages a like wheel 19 on the short horizontal shaft 20. The latter has a sprocket-wheel from which the link belt 21 (see Figs. 6 and 7) is driven. The belt passes across the machine to the sprocket-wheel 22 on the opposite side, and its function is to rotate the short shafts 28, having the cog-wheels 24:, which engage the cog-wheels 25 on the twister-shafts above said shafts 23.

Mounted on shaft 9 at the other side of the frame A is the wheel 7 6, having the side teeth 12, which, like the teeth 12 on the wheel 10,

extend less than half-way around said wheel.

' The wheels 76 and 10 are set so their teeth 12 and 12 will be on diametrically opposite sides. A vertical shaft 15 has the bevel-pinion 14: The latter engages the teeth 12. It also has the wing-plate 16 to keep the wheel 14 from revolving when the latter is not in engagement with the teeth 12. The shaft 15 has the bevel-wheel 18, which engages the wheel 19 on the shaft carrying sprocket-wheel 22. By the above-described mechanism the link belt 21 is driven in alternate opposite directions during each revolution of the shaft 9, with intervals of rest between each change in the direction of said belt movement. The twister-shafts hereinafterto be described are correspondingly rotated to the right and then to the left, and so on,'with intermediate pauses.

It is essential that all of the twister-shafts rotate equally and simultaneously; but as they are not uniform distances apart, but are grouped in three divisions, corresponding with the arrangement as to distances from each other of the horizontal fence-wires, 1 connect up the twister-shafts, through their associated shafts 23, as follows: The first live wheels 24 being those which operate the twisters for the bottom and closest wires of the fence engage with one another, as shown in Fig. 5. The wheels 24: must be of the same diameter for all of the twisters to insure a uniform speed to all of said twisters, and as the next four of the latter are farther apart than the first live the cog-wheels 21 will not make engagement with each other. 1 therefore extend their shafts 23 and mount the larger cogwheels 25 thereon, thereby connecting said four shafts in a series, which is connected with the series comprised of the first live shafts by the cog- wheels 26 and 27 on the extensions of the adjacent shafts of said series. In like manner the last live shafts are connected in series by cog-wheels 28, and that series is connected with the middle one by means of the cog- wheels 29 and 30. One shaft of each of the three series has a sprocket-wheel 31, which is engaged by the link belt 21, whereby, in connection with the remaining aforesaid mechanism, all of the shafts 23, and through them all of the twister-shafts, are uni formly related. The said twister-shafts are each provided with a central longitudinal hole, through which the horizontal wires 1 are threaded, and opposite said hole and diametrically opposite each other are two holes longitudinal of said shaft, through which two of the cross-wires are threaded. One wire of each of these pairs'is from a spool of the near or inner row of spools, and the other is from a spool of the far or outer row of spools. The cross-wires will only be threaded through each alternate twistershaft. Each twister-shaft will comprise live separable parts, (see Figs. 9 and 10,) a middle cylindrical part upon which the wheel 25 is mounted and having the integral middle cylinder-segments 32 on either side of the wheel 25, and the double pair of shorter integral cylinder-segments 33, having 'liat inner faces which are parallel with the adjacent and also flat face of middle segment 32. Between said middle segments and each of the four outside shorter segments are the removable cylinder-segments 3 f, which when placed as in Fig. 10 fill out the full contour of the twistershaft. The above-described middle portion of the twister-shaft,which I call the body portion, is mounted in suitable transverse indents in the top of a cross-bar 35, reaching across the frame A and also having suitable recesses to receive the wheels 25. The displacement of these parts is prevented by a cap-bar 36, also having suitable recesses to receive and hold the said body and wheels, as shown in Figs. 5 and'S. Mounted in suitable channelsin the top of the cross-bar 35, under the removable shaft-segments 3a, are the longitudinally-reciprocating bars 37, with seats to receive the said segments, which seats also serve to give engagement between the bars and the segments, whereby when the joints of the twistercarried from its first shaft tothe onenext adjacent toit. Through these removable'segments are the holes which carry the cross-wires. Deep grooves or notches 38 allow for the passage" of the wiresgthro'ug-h the cog-wheels 25 and supporting-shaft, so that the cross-wiresfreedom laterally of said wheels. The bars 37 are in pairs on either side of wheels 25? and bearingsforthe said wheels; Each of the three previously-described series of twi'ster-- shafts has a separate pair of said longitudi nally-reciprocating bars and each pair'of barsare connected by link- bars 39, 40, and 41', re-' spectively, with cross-bars42 43, and 44,-respectively, atone end of the cross-bar 35; (see Figs. 6 and 7,) and the latter'are" connected by links or pitmen 45 with the lever 46;- Bya throw of the lever 4'6 all" of the bars 37 are proportionately moved,so asto cause th'e'crosswire-carrying shaft-segments to change places with a set next to each one movedyand a re verse movement of said lever will bring them back tofirst position. The top' removable twister-segments are moved in a like manner by means of the cap-plates 4 7, also-in three sections for the three series of segments, which platesare connected bypi tme'n 48 with the lever 46 on the other side of its fulcrum, whereby the top twister-segments Will be moved simultaneously with'th'e movement of the lower one, but in an opposite direction, which is necessary in order to present the cross-wires in right relation to produce a diamond-mesh fence. The segments havethe flanges 49, which enter corresponding grooves in theirretaining seat and cap, whereby movement of said segments longitudinally of the twister-shaft is prevented. Saidsegment's al'so have tubular guides 50 for' the cross-wires, which are pivoted on trunnions at their inner end and are adjustable radially. of the twisters at their outer ends, whereby the distancesof the cross-wires fromthe horizontaliwires may be-regulated.

It will be recalled that wheel 10, with its mutilated side wheel, imparts an intermittent movement to the shaft 15=and thatsa'id' intermittent-movement is imparted through the de scribed mechanism to the twister shafts. These quiet intervals are for the purpose of allowing an exchange of tw'istershaft segments. I

Crossing the axisof revolution of the'wheel 10 at right angles to shaft" 1 5 is the shaft 51, which is-supported by the frame A in suitable boxes 52. This shaft has the bevelpinion 53, which is given a half revolution, thereby imparting a' like movement to the shaft twice during each revolution-of wheel- 10 by means of the teeth 54 54 on the side of wheel 10; The shaft '51 also carries the wingplate 55,- whichslides along the flat face of 5 track 56, extending between said cog groups 54 54. Depressions opposite the cog-groups allow' the' wingeplate to rotate while the pinion 53 is engaging'sai'd cogs 54. The shaft 51 has the end crank 57 which isconnected by the l ink' bar'58 with the extension-arm 59' from thesaid" lever'46L The'shifting of the twister' V segments is controlled from this lever 4,6.- may be removed and introduced with perfect: 3

I will next describe; the carriers by means of which the wires are kept from entanglementbefore reaching the twisters. The spools 4, referred tom the early part of this specification as carrying the supply of cross-wires, are mounted between circular revolving heads '60; and theheads are connected by a half-cylindrical-shell6l, which insures uniform rotation of the pair of heads for each spool.

These head's-are separated sufficiently to prevent contact with each other, anduponand are supported by an under row of heads 62, which are joined in pairs by means of shaftsand situated so that each upper head vhas a bearing equally upon two lower-heads,

and in consequence the number of lower' headsis one greaterthan that-of the upper they rest row. The headsin both upper and lower f rows have circumferential cogs, which mesh with each other at the contact-points, whereby "when rotary movement isgi-ven'to one of the hea'ds -of aserie'sall of those in the train connected withit will revolve,- and by the arrangement' above described the top'row of. heads will allrevolve in the same direction, while the bottom row will revolve all in the same direction, but oppositely to the direction of'the top row; The row of heads next to the body A-is driven by shafts 63 63,-which inturn are driven through bevel-gears 64 from theshaft 65, and the latter is driven by link- -b'elt connection v66 from the revoluble "shaft 9'. The outer rows of heads are connected with t'he'said inner row by means of the'respectiveshafts 67 67 and 68 68, whereby the head's inall fourrows will be uniformly rotated.

69 represents rigid stationary plates, one for each row of heads, having circular openings through which the heads of the row or series to which the given plate belongs are inserted in the manner shown in Figs; 13, 14, 15, and 16;- As shown in Fig; 16 and indicated by the inner dottedcircles of Fig. 15, the said heads have circumferential grooves 7 O, and intothese grooves'the plates enter by reason of the openings in said plates being less in diameter than the body of the head. The heads .have transverse grooves 71, in which the fence-wires are laid. These grooves extendto about the bottoms of thecircumferential grooves'l'O, and whenthe fence-wires arein' the transverse grooves they will be carried around-with the rotating heads and will" rotated twice around.

pass under or inside of the plates, the latter serving as guards to hold the wires in the transverse grooves except at certain predetermined points where it is desired to shift the wire from the groove of one disk into a similar groove in an adjacent disk or head. This shift is made coincident with the exchange of the 'cross-wires between the twisters, and as the twisters turn in alternate opposite directions a corresponding change in the direction of movement of carrying-heads is required. The horizontal wires 1 are first threaded through the grooves of the heads, one wire to each lower groove, when the heads are set or turned with wire-grooves on the lower sides. The wires 1, which run to the twisters having odd numbers, counting from i the bottom of the fence, are threaded through the grooves in the bottom tier of heads, and the wires going to the even numbers of twisters are threaded through the grooves in the upper tier of heads. The cross-wires from the outer row of spools are threaded through the left sides of the upper row of heads of the inner row of spools. The wires from the inner row of spools are threaded through the adjacent spool-heads or heads next to the machine and are carried directly to the twister to which the horizontal wire from that spool is carried. All of the drums in both rows are The drums in the upper rows by going in the same direction as the twisters to which their wires are connected twist each pair of cross-wires twice around the horizontal wire of that twister. The above movement of the carriers prevents a twist in the wires except on the inner side of the twisters. The twisters are halted after they have made two revolutions, and the shift in the cross-wires is made. Then the twisters are rotated two revolutions in a reverse direction. Simultaneously with the above shifts of the wires at the twisters the cross- .wires are shifted laterally to a corresponding adjacent top carrier -head, and coincident with this shift of the cross-wires the horizontal wires change places from a lower drum to a higher one geared to it. The twisters and carriers are given two revolutions to twist the cross-wires around the set of horizontal wires of the new set of twisters. Then a reverse shift of wires is made back to the twisters and carriers from which they started,

. and the above-described operations are successively repeated throughout the weaving of the desired amount of fence. The twisters when in motlon have a greater speed than the drums in order to make up the time lost by their pauses in crossing the wires. The horizontal wires 1 are shifted from a lower to upper head and back by the pointed end of the .bent lever 62 in the outer set of carriers.

There is one lever for each pair of heads, as shown in Fig. 16. The levers have the fixed pivots 63 and are pivotally secured at their lower ends to a common shifting bar 64-. This bar 6 is shifted longitudinally by a crank 65 on a rock-shaft 66, which extends back under the machine-body A and has a crank arm which is connected by red 67, Fig. 1, with the crank 68 on shaft 69. The latter shaft has a crank 7 O, which is connected by rod v71 with crank 72 on the shaft (3'. The shaft 73 has the two bevel-pinions 741 and 75 placed diametrically opposite each other with relation to the wheel 76. The wheel 76 turns with shaft 9, on which it is mounted, and has the group of bevel-teeth 77, which engage the bevel-wheels 7-1 and (5 during each revolution of wheel 76 and rotate said bevel-pinions one complete revolution each time. Rotation of the latter, except when in contact with the teeth 77, is prevented by the wing-plates 78 at the inner ends of the bevel-wheels, which travel over the fiat table 79, except when next said teeth 77, where the depression 80 occurs, which permits the wings to rotate.

The handling of the wires for the inner tier of carriers is more difiicult for the reason that the cross-wire from the outer spools must be kept clear of entanglement, which requires that they be shifted back and forth between pairs of heads all in the top row after each double revolution. To make this transfer, I provide the small intermediate cog-wheelsSl, (see Figs. 13 and 15,) under which the wire 5 passes in going from right to left, Fig. 15, and over which the said cross-wire passes in going from left to right. The horizontal wires 1 are shifted from lower head to upper and back by means of the pointed lever 82. similar to the lever 62, previously described, for the outer tier of heads. Lovers 82 have in addition the pivotally-attached arms 83, which terminate with the curved guard S110 prevent the escape of the wire from the cogs of wheel 81 during transit. The arms each have the points 85, which cross the path of the wire in the upper wheel to its right when in the position shown by full lines in Fi 15, and that position is the one into which it is forced by the spring 86, carried by the pointed end of lever 82. A stop consisting of a lug 87 from the stationary plate 69 arrests the arm in right position; but when the lever 82 is movedinto the position shown by the dotted lines in Fig. 15 a lug 88 on said lever engages the lug 89 on the hinge end of the arm 83 and raises the arm to the dotted position out of the path of the wire in the upper head. The shift of the wire 5 toward the right over the wheel 81 is compelled by the pointed lever 90, when it is thrown into the position shown by the dotted lines in Fig. 15. The lever 90 has the stationary pivot 91, and its upper end is pivotally secured to the bar 92. The lower lever 82 is pivotally attached to a bar 93, which, as shown in Fig. 13, is part of a continuous frame, whereby both will move together. As the lower lever requires a longer throw than the upper one,

I provide the slot 94 in bar 92 to allow for difference in movement. The frame thus pro- 1 vided is longitudinally reciprocated by crank 100, which is connected by rod 101 with crank 102 on the shaft 51, which, as has been previously described, has an intermittent movement from wheel 10.

The Wheels 102 are friction-Wheels to help support the heads andmake them run easy,

Located between the outer tier of horizontal spools and the vertical spools 2 are the tension-wheels 103 to keep the wires from reeling off of the spools 2 too rapidly.

and pitmcn connecting the caps with said pivoted lever at points above the pivot, and pitmcn connecting said under bars with the lever at points below the pivotal point of said lever.

14. In a fence-weaving machine, a munber of wire-twisters equal to the number of longitudinal wires in the fence to be woven, carriers moving in opposite directions from every horizontal wire where a twist has just been made, to the next adjacent horizontal wire, spools of a number less by one than the munber of longitudinal wires, each carrying a cross-wire and arranged in a double row, rotating heads in pairs, between each of which pairs one of said spools is mounted, said heads having peripheral cogs, an intermediate series of heads under those carrying the spools, said under heads having cogs and making driving connection between each pair of upper heads, and means for shifting the wires from one head to an adjacent one in harmony with the movements of the twister-shafts.

15. In a fence-weaving machine, a number of wire-twisters equal to the number of longitudinal wires in the fence to be woven, carriers moving in opposite directions from each horizontal wire around which a twist has just been made to thenext adjacent horizonal wire, spools of a number less by one than the number of longitudinal wires, each carrying a cross-wire and arranged in a double row, rotating heads in pairs between each of which pairs one of said spools is mounted, said heads having peripheral cogs, an int ermediate series of heads under those carrying the spools, said under heads having cogs and making driving connection between each pair of upper heads, and small cog-wheels between the upper series of heads of the inner row of carriers to carry the cross-wire from one top head to an adjacent one.

16. In a fence-weaving machine, a number llS of wire-twisters equal to the number of Ion-T gitudinal wires in the fence to be woven, carriers moving in opposite directions from each horizontal wire where a twist has just been made, to the next adjacent horizontal wire, spools of a number less by one than the number of longitudinal wires each carrying a cross-wire and arranged in a double row, rotating heads in pairs between each of which pair of heads one-of said spools is mounted, said heads having peripheral cogs, an intermediate series of heads under those which carry the spools, said under heads having cogs and making driving connection between the heads of each two ad acent upper spools, cross-wlre-carrylng p1n1ons between the up- 7 per series of heads of the inner row of carriers, pointed levers each separately pivoted between its ends to fixed supports and at their lower ends to frames 01' bars reciprocating longitudinally of the row of spools to which the frame relates and rocking shafts to reciprocate the respective frames and move the pointed levers across the paths of the wires to shift them from one carrying-head to another.

In witness whereof I have hereunto set my hand and seal atIndianapolis, Indiana, this 23d day of October, A. D. 1902.
