To aZZ whom Vit naa/y concern Be it known that I, JOHN W.``DWIGGINS, a

' citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful 'Improvements inv Wire-Fence Machines; and I do declare the following to be a f ull,1ear, 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, refer ence beinghad to the accompanying drawings, and to the' letters and figures of reference marked thereon, .which vform 'a part of this specification. 1

My invention relates to improvements in wire-fence `machines of the class adapted to be operated by power other than hand-power for the purpose of weaving a series of wire pickets into a series of longitudinal wires, thereby producing woven wire fencing.

The objectsof my. invention are, first, to provide a means in a wire-fence machine for automatically reversing the movement' of the twister-wheels, so as to alternate the direction of the twist in the wires between the pickets; second, a mean's for antomatically carrying the horizontal wires forward, after a twist is formed therein, a suiiicient distance to receive another twist; third, a

means for automatically holding the horizontal wires in engagement with the twisterwheels while the twists are being formed; fourth, a means for automatically bringing the twister-wheels into contact with the g zontal wires fifth, a means for automatically reeling the woven fencing into suitable rolls;

p after passing the twisters; ninth, a means for `carrying the twister-wheels.

' limproved wire-fence machine will be explained hereinafter. A

My invention consists in the construction, combination, and arrangement of the machine and various parts thereof, which are described inthe following specification and more particularly pointed out in the claims.

These views I deem necessary to properly show my invention, and like letters or g- I:

ures of reference in the differentviews show-n in the drawings refer to like parts.

The frame of the machine consists of uprights A and A', cross-pieces B and B', and supports C and C..' Uponthis framework are mounted the various parts composing the complete machine. i The power is applied to the band-wheel a, which `is loosely mounted on a short shaft h. A friction-clutch c`,having the lever c', is also mounted `on, said sha'ft b and is adapted to engage the prog'eetinzgdiub a.' Upon the shaft b is,

-meshes with the large bevel-gear'f"", mounted Qn the shaft E. Upon the shaftE (shown detached in Fig. l1) are also mounted a wheel g, having an eccentric groove formed in its .outer rim or peripheryhsaid groove extending entirely around its circumference, a sprocket-wheel h, a trip-arm i, and' two operating-armsj, provided with small flat-faced rollers k, j ournaledl in each end thereof. Said yshaft E is suitably mounted upon the frame.

Upon a bar Z, secured at each end to the framework, is provided a bent lever m, which is -best seen in Figs. 13 and 14, said lever being provided with a small roller 7c', adjustably. mounted near one end, said roller being adapted to enter and travel in' the groove in the wheel g. Near the opposite end thelever has a half-twist, which brings the flat sides at right angles to the' flat sides of the end carrying the roller k'. On said opposite end is formed a fork fn,- which engages a groove 0 in a sliding collar p, which is mounted on the shaft D between the bevel-gears f' and f". The collar p is provided with teeth o' on either end, which engage with teeth lr' on the `hubs of the bevels f'and f". The eccentric groove in the periphery of thewheel g, in which the roller 7c travels, imparts an oscillating movement to the lever lm, which serves to slide the collar p backward and forward slowly on '.the shaft l), causing it to alternately engage the bevels f and f", and thereby reverse the movement of said" shaft. Upon the outer end of the shaft D is iixedly mounted an ec- .centric wheel s, which is provided with projecting ears t and t'. The trip-levert', which is formed with one arm of greater length than the other, has small rollers 7c" mounted on each end thereof. These rollers are adapted to alternately strike the ears t and t', which checks the movement of the shaft D and allows the collar p to slide freely without bindi' ing, as would be the case were it to travel under tensionl The collar p is held from turning on the shaft D by means of a key in the shaft, the

collar being grooved to lit over the key. The

long end of thelever strikes the earand the short end the ear t', thereby giving atensiontrip for both the bevels f' and f". A further 7o 'tension for the shaft D is provided by means Hof the friction-bearing F, which is regulated by means of a coil-spring G and nut u.: The

shaft'D`eXtends the-full width of the frame- Work, and between the cross-pieces B B' has 75 "a suitable number of-bevelcogs c mounted therebn'and adjustably seeuredtheretoby -.frame H is pivoted between thefcrss-'pieces B B and'is so placed that the bevel-cogs o',- o

. mounted on the ends' bf the shafts I, will mesh with the cogs 'v onthe shaft D. On the opposite ends of the shafts H are mounted the twisters J, of ordinary construction, en

larged views of which, Figs. 8 and 9, show 85 theirl construeti'on'and manner of attachment to the frame H. The twisters consist o-f a plain cog e2 and a 'slotted cog es, mounted in casin-gs are provided'with slots 0". A

shaft K (shown detached in Fig. 16) is mount- 9o ed against the iont uprights A, and below the cross-pieces B carries a sprocket-wheel h' onone end a `d a cam-lever w upon the other end'. Two'- cams w' are also mounted on said shaft at a\ sufficient distance apart'to 95 lie beneath the end piecesH' of the twisterframe H. It is by means of the cams w' that the vtwister frame is raised and lowered, thereby bringing the twisters into engage! ment with' the horizontalwires a. y

bar Z', pivotally attached to the 4right crosspiece B. A rod L is suitably mounted inside the front uprights A and is provided .with two arms M and a lever-arm M', all-:e5I

lixedly connected to the rod. The outer end of the lever-arm M' is connected with the bent lever Z' by means of a rod N,- which is pivotally attached to each. To the outer ends of the arms M are pivotally connected de- 1ro pending rods N', which are attached at their lower ends to a horizontal slotted bar-L', said bar being provided with guides at either end, said guides being adapted to slide vertically upon the guide-posts O, secured toghe 1 15 cross-pieces B B'. Said bar L' is provi ed with wire-holders y, having U-shaped slots in their depending ends, which are adapted to hold the horizontal wires 0.' in the slots` in the twister-wheels while the twist is being 12o formed inthe wires. This part of the machine is best seen in Fig. 5. The barl` L', with the wire-holders y,.is raised and lowered by means of the cam-lever `w raising the bent lever Z',which causes the rod Nto lift the 1,25

lever-arm M', thereby slightlv rotating the rod L, which in turn lifts @les arms M, causing the rods' N' to raise the oar L'.

` The shaft`1 lia'sifin'ounted `upon it three sprocket-'wheelst", the sprocket-wheels L'", 13o

the star-feed D', having the radial arms, and the open drum having the projecting portions s", which rise above the outside diameter of the sprocket-wheels h" for the purpose of "10(- The cam-leverw is adapted to engage a bent lifting-the woven fence out of the picketholdcrs and wire-guides. rlhis shaft and its connection are best seen in Fig. The reel Q, which may be of any suitable construction, is provided with a fixed shaft, one end of which is :formed with -a depression 2 and the other end with a clutch 3, as shown in Fig. This rcel is adapted to be supported at one end by mea-ns of a threaded bearing 1L, mounted on the support C, which receives a set-screw 5, having a pointed end which enters the depression 2 in the shaft and turns therein. Said setscrew is adapted to be turned by hand and is provided with a locknut G, which prevents its turning when the rcel is in operation. Upon the opposite support C is a bearing 7, which supports one end of a short shaft R, the outer end of which is sul'ported by a bearing 7', supported by braces S and 8'. The inner end'of said shaft R is provided with a clutch 3', which engages with the clutch 3 upon the end of the reelshaft, and thereby supports vthat end of the reel Q. A friction-disk il, having a sleeve lO, is iminovably secured to the shaft R, and a sprocket-Wheel Al1 is loosely mounted upon -said sleeve, the length of said sleeve and thickness of sprocket-wheel being substantially the same. A friction-disk 9', without a sleeve, is placed next the opposite side of the sprocket-wheel 1l, and is also secured to the shaft. From the disk 9 to the bearing 7 the shaft is threaded, as shown at 12, and is surrounded by a coil tension-.spring 13, one end of which bears against the friction-disk 9 and the other end against the nut G, by

means of which the tension of said spring isk regulated.

Figs. 17 and 18 illustrate thedeviee whereby the woven 'fencing is held against lifting until it has passed a suicient distance beA youd the twisters. It consists of angular end frames 14, secured upon the cross-pieces ll B. To these end frames are bolted the slotted bars L", and hangers: 15, bolted through the slots, and to the lowerends of said hangers are attached bars 1G, rounrY ed at both ends, beneath which the woven fencing slides. This prevents the fencing lifting out of the pickest-holder.V and wire-guides until it has passe" begaf/sid the bars 16, when itis engaged by tu: projecting portions ,a of the open drum or cylinder, when itis disengaged and passed onto the reel (3. ,'lhis action is best illustrated in Fig. il). The above-described portion of the machine is not illustrated in Fig. et. y Extending across the 'front end of the machine is a slotted bar S, to which are bolted the wire-tension devices.: 17, which tension the lower wires, andare illustrated inFig. 7. 'lhe desired tension is obtained by turning the grooved spools 18, over which the wire passes, into the desired position, tightening the bolt 19, thereby securingr the plate 2O against turning. A similar slotted bar S, to which are attached like devices. to tension the upper wires, is attach ed to the cross-pieces B B near their front ends, the upperwires rst passing over the spools 18, mounted onthe rod T,

which is secured to the uprights Aby means of the brackets 21.

Near the front ends of the supports C are bearings 7 which support a shaft U, upon which are mounted three sprocket-Wheels hf" of a size corresponding with the sprocketwheels It". These sprocket-wheels h and h each carry a sprocket-chain 22, to which are secured the bars V, carrying the picketholders and Wire-guides. A section of chain and one of the bars Vare shown detached in Fig. U. These form an endless carrier passing over and under the machine. The picketholders and wire-guides are formed by pins 23 and lugs 24, attached to the bars V. A shaft lV, mounted between the cross-pieces B l5, carries three small sprocket-wheels 25 and serves to support the sprocket-chains at that point. This may be seen in Fig. 10. A short sprocket chain 22 connects the sprocket-wheels 7L and 7d, and a sprocketchain 22 connects the sprockets l1 and i'".

In operation the band-wheel a is connected f by a belt with a suitable power-shaft. The level` c' is thrown to cause the clutch c to engage the hub d of the band-wheel a, which causes the shaft b to revolve, when the bevelgear j" on the end thereof will cause the loosely-mounted bevel-gears f and ff" to revolve on the shaft D.

The small cog-wheel e, mounted on the shaft I, meshes with the large cog-wheel e, which causes the shaft l1 to revolve, and the small bevel f", mounted on the end thereof and meshing with the large bevel-gearf"", causes the shaft E to revolve, and this revolves the grooved wheel g, the trip-arm t', the operating-armsj, and the sprocket-Wheel 7L, mounted thereon. The grooved Wheel g imparts an oscillating motion to thc bent lever m, pivotally mounted on the bar Z, by reason of the roller 7s on the end thereof resting in the eccentric groove in the wheel g, thereby causing the sliding eollarp to slide backward and forward upon the shaft D, the teeth r on said collar alternately engaging the teeth o" on the bevelsf and f". The eollarp, sliding on a key in the shaft, will cause the shaft to revolve when the teeth on -the collar engage the teeth on either bevel, as the bevels f and fare constantly rotatedby the bevel f. The movement is so timed that when the shaft has revolved the requisite number of times that one of the rollers 7c" on the trip-arm 1I will strike one of the ears tor t on the eccentric wheel s', thereby checking the motion of the shaft l) and releasing the tension on the teeth r and r' an d the grooved wheel g, simultaneously reaching a point that causes the lever m to slide the collarp out of engagement with the bevelwheel. The collar p dwells slightly in its movement between the bevelsf' andf, the shaft 'D in the meantime remaining stationary. The collar p, reaching its opposite limit, will engage the opposite bevel and thereby again revolve the shaft but, as

Vzo

will be seen, in an opposite direction. revolvingof the shaft D revolves the small bevels 1:, iixedlymounted thereon, andv they in turn mesh with the bevels o', mounted on the shafts I in the twister-wheel frame H, thus revolving them and thereby operating the twisters J, connected therewith. It will therefore be apparent that the. Wires passing through the machine will be given alternately a right and left twist.

The operating-arms j on either end of the shaft E revolve with the shaft and are so placed that the rollers lc in each end of said arms will comefin contact with one of the radial arms of the star-feed D', the rollers serving to reduce the friction of contact. This contact raises the radial arm until the roller passes it, and thereby slightly rotates the sha-ft P, upon which the star-feed D is mounted, and at the same time brings th'e next radial arm into position, so the other end of the arm j will engage it in a likemanner. It is thus that the endless carrier, composed of the sprocket-chaius'22 and the bars V, is moved forward, stopping between' each forward move long enough to allow the twisters to operate. Thesprocket-wheel h on the shaft Eimparts motion to the shaft K by lmeans ofvthev sprocket-chain 22 andthe sprocket-Wheel h on said shaft K. Th-e'cams w, mounted on the shaft K, .are so placed asftosupport thev twister-wheel frame H and as'thegshattlref volves alternately rais'eland lower said frame, thereby bringing the twisters into contact with the wires et while the twist is bein g fored p and allowing it to drop away while the operating-arms are moving the endless carrier which carries the wires and pickets.

The cam-lever w on the end ofthevsfhaft K engages the bent bar Z', which i's otd with the lever-arm M by the rod N, thereby causing the wire-holders y, secured to the slotted bar L', having the guides .'r, to be raised and lowered on the guide-posts O through Y the medium of the arms M and rod L. The

vertical movementof slotted barL is so timed thatl when the twisters are naised to thewires by the camsw the said bar-LQis lowered, with the holders y, upon the wires ct', and when the twisters are lowered the bar is raised. The

purpose of this part of the machine is to,

firmly hold the horizontal wires af within the slots o of the twisters.

The shaft I), which is rotated through the medium of the star-feed D by the arms, has the sprocket-wheels h, which carry the endless ca'rrier, and the open drum having the projecting port-ions z of greater diam eter than the sprocket-wheels 7L", thereby causing said projecting portions to lift the woven fence out of the picket-holders and wire-guides as the endless carrier is carried on to and over the sprocketwheels and the woven Wire fencing is passed on to the reel Q. The reel Q is operated by means of a sprocket-chain 0"" shaftiP withthe sphrqlgetwheell l., mounted between the friction-disks 9 and 9". It is oblvious that the reel Q will have to make a /greater number of revolutions to reel a given number of feet-of wire fence when the .reel is nearly empty than when almost full, as the diameter 'of the roll constantly-increases as the fence is-wound upon it.

To regulate the speed of the reel, I provide `theifriction-disks, which allow the sprocketwheel ll to slip between the disks as the reel ills and the diameter of the roll increases, thereby insuring an even tension in the roll and at the same time preventing the reel from straining the machine by drawing too heavily on the wire. The tension of the disks 9 and 9 against the sprocket-wheel 11 is securedand regulated by thespring 13 and nut 6. The'distance between the horizontal wires a', betweenuvhich the wire pickets are woven, is regulated by adjusting the tension devices @119m the bars S and S', the picket-holders, t e twisters, and the small bevels 'u and v', thereby allowing the machine to weave va- Ifious designs of fencing. The horizontal wires ctare brought to the machine from suitable reels, the upper wires passing over the spools 18' and the-tension devices 17, where they meet the, lower wires,which come over the tension devices on the bar S at the front 'ofthe machine. The pickets are placed upon the lower wirespwhichlie lbetween the wire guides 23 onthe bars. V atithe front end of the machine', by the attendant and are held from slipping by the picket-,holders 24. As thevendless carrier moves forward the picket is carried und'erthe upperv horizontal wire, and when itreaches the twistersit is firmly twisted between the upper and lower horif zontal wires.`r
