To @ZZ whom it may concern,.-

Be it known that I, ALBERT J. Barns, a eiti zen ofthe United States of America, residing at Joliet, in the county of Till and State of Illinois, have invented certain new and useful Improvements in Wire-Barbing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in wirc-barbing machines of that class adapted to forni and apply two pointed-wire barbs to thestrand-wires of wire iences, which improvements are fully set lforth and explained in the following specification and claims, reterence being had to the drawings, and thelctters and figures marked thereon, making a part of this specification, in which- Figure 1 is a perspective view of the machine, showing a portion of a twisting-yoke attached thereto. Fig. 2 is atop plan view of the same. Fig. 3 is a perspective view of a portion ofthe slotted stationary barb-support. Fig. 4t is a top plan view of aseeondary bed for supporting the barb-wire guide, stationary barb-cutter, and slotted stationary barb-sup port. Fig. 5 is a perspective view ofthe upper end ofthe punch for forming the central Ushaped bend in the barb. Fig. 6 is a perspective View ofthe rotating barb cutter and bender. Fig. 7 is a perspective View of one of the finishing barb-benders. Fig. 8 is aside view of a stationary dividing-plate, showing its end that stands between the prods of the barb to hold them separated while they are being bent or clasped on the strand-wires. Fig. 9 is a vertical cross-section ofthe machine, taken on line 5 of Fig. 2, lookingin the direction of the arrow. Fig. 10 is a vertical longitudinal section of the machine, taken4 on line 4 of Fig. 2, looking in the direction of the arrow. Fig. 11 is a side view ofthe oscillating head for holding and operating the punch for forming the central U-shaped bend in the barb. Fig. 12 is a detail side view of a pivotal box for connecting said oscillating head with its operating-pitman. Fig. 13 isa tace plan view of the channel-cam for operating said oscillating head through the medium of apitman and a wrist-roller in its channel. Fig. 14. is a perspective view ofthe front end of the reciprocating barb-forming-die, which also serves as a strandwire guide. Fig. 15 is a cross-sectional view through the reciprocating head forsupporti ng said die, taken on line 6 of Fig. 16. Fig. 1G is a side view of the reciprocating head for holdingsaid barb-forming die and ofthe two cranks for supporting and operating said head. Figs. 17, 1S, 19, 20, and 2l are detail views showing the several im-` mediate parts of the machine that cut and form the barb and attach it to the strandwires, and showing a barb in its several stages offormation. Fig. 22 isa side perspective view of a pair ot' feedrolls for flattening and feeding the barb-wire in the machine; and Fig. 23 is a perspective view of a section of the finished barbed wire, it being the product of the machine.

Referring to said drawings, and the letters and figures thereon, like letters designating s'milar parts inthe several figures, B is the miin frame or bed of the machine, supporting the working parts, and is supported by means of the legs L.

S'l is the drive shaft,supported in the bones T and T and provided on one end with a fast pulley, Q, to which the power is applied, and a loose pulley, Q. The said drive-shaft is connected with a pair of side shafts, S and S', resting in the boxes TZ T T Tl", by means of the unter-gears R and R', by means of which connection the said shafts are caused to rotate in opposite directions from each other. Shaft S has fixed on its outer` end a spur-gear, g, to rotate a twister-yoke, A, only a portion of which is shown, as it forms no part of this invention. Said shaft has also fixed thereon the head J', for holding the primary rotary barb` bender D3, and also the spur-gear C. Shaft S is about half as long as shaft S, and has fixed on its outer end the head J, for holding the primary rotary barb cutter and bender D. These two heads J and J are arranged to stand exactly opposite to each other and in the relative position shown in Figs. 1, 2, and 9. Said shaft S has also fixed thereon the spur-gear G2.

K and K are a pair of curved standards se cured on the side o1' hed B, and provided at their upper ends with boxes for supporting, respectively the short shafts S3 and S, (Shown particu- IOS larlyin Fig.10.) SaidshaftS3hasfixed onits outer end the spur-gear G, that meshes with spurgear G2, as shown in Figs. 1 and 2, and has iiXed on its inner end the rotating head d, in which is fixed the secondary barb-bender C. Shaft S* has fixed on its outer end the spurl gear G', that meshes with spur-gear G,and has fixed on its inner end the rotating head d', in which is fixed the secondary barb-bender C. Said shafts are set so said rotating heads are a little distance apart and exactly face each other over the central part of the machine, as shown in Fig. 9, and. by means of said spur-gears are caused to rotate in opposite directions from each other. y

B is a secondary bed secured to the top of bed B, and is shown in Figs. 1, 2, and in detail in Fig. 4, and is arranged to support the stationary barb-cutter D2 in such manner that the rotating cutter and bender D will shear therewitlrto cut off diagonally the barbs b from the barbing-w'ire b, so they will have sharp prods. The barb-support F is also supported by said secondary bed in. such manner as to operate in conjunction with the forming-die F and punch P, as will. hereinafter be fully eX- plained, and a barbing-wire chanuel-guide,R3, is also supported by said bed in such manner as to conduct the barbiug-wire from the feedrolls E E, between the cutters D. and D2 and diagonally across the slotted end of the barbsupport F, where the barbs are formed and secured to the strand-wires.

The barb-support F is shown in detail in Fig. 3, and has formed on its upper side at its engaging end hooks h,for retaining` thc barb in its proper place on its said support while being formed, and is slotted at that end between said hooks, as'shown in Fig. 3 at h', for the admission of the punch P, which passes up through said slot to form the central bend in the barb.

E2 represents an oscillating head for snpporting and operating punch P, and is shown in Figs. 9 and 10 and in detail in Fig. 11. This head hinges to the ear-ln gs Oand O', which are integral with the front part of bed B, and,

by means of two ear-lugs of said head, in such manner as to permit finished barbed wire to pass between them, as shown in Fig. 2. The punch P is secured in said head by means of a cap screw and plate, i, and is made adjustable vertically by means of the set screw i. rllhe lower side of said head is provided with a pivoted box, E, for the attachment to said head of the lower end of the pitman P2. (Shown in Fig. 10.) The head Z of said pitman forks over drive-shaft S2, and is provided on its side with a friction roller and wrist, Z2, for operating in the channel of cam-wheel Z, fixed on said shaft. Said head E2 is caused to oscillate to operate said punch by means of said cam through the medium of said pitman. Proper set-nuts on said pitman furnish means to adjust the head E2. The upper end of said punch l? is shown in detail in Fig. 5, to show its exact form as having a slight depression,

p, in its upper end and at each side thereof, arranged at an angle from each other to correspond with the form and position of the barb, and for the purpose of assisting to hold the barb in place while its prods are bent.

H is a reciprocating head supported by means of crank H/ on the end of a rock-shaft passing through box M, Figs. 2, 10, and 16, and idler-crank H2, boxed to the machine-bed, as shown at M', Fig. 10. Said rock shaft is provided with a crank, a2, at its opposite end, and is connected with eccentric a on shaft S'i through the medium of eccentric pitman a. Said head H is caused to reciprocate by means of said eccentric through the medium of said eccentric pitnian and cranked rock-shaft, and is shown in Figs. 2, 10, and in detail in Fig. 16, the reverse movement being shown in dotted lines in said figure, and a cross-section of the head taken on line G of said Fig. 16 is shown in Fig. 15. In said Fig. 15 thehead. is shown as having a channel for the reception of Athe strand-wire guide and forming-die F, held therein by means of a cap-plate, H3.

W YV represent the channels in the sides of said guide and forming-die for the passage and guidance of the strand wires W" \V. Said guide and forming die is shown in perspective in Fig. 14, and is represented as having its lower side channeled at W2 below and between said channels \V W. Thefront end of said die and guide F projects out beyond and in front of said head H, as shown in Fig. 1G, some little distance, and when the head H is in the position shown in the full lines in said figure the front end of said die will face the front end of the barb-support F, as shown in said figure and in Fig, 19, because of the backward inclination of its supportiiig-cranks. The reverse movement of said head, caused by turning said cranks forward to a perpendicular position, will place the projecting end of said die F above the slotted end ol" said barb support F, as shown in Figs. 10 and 17 and by dotted lines in Fig. 16, so the channel YW in its lower side will be immediately over the slot h in the said barb-support, so that when the punch l? passes up through said slot it will drive the central part of the barb upward into said channel NV of said die, as shown in Figs. 9, 17, and 20, to form the central U -shaped bend therein. Said head H also supports the double-grooved sheave-wheel V on its rear upper side, which wheel serves to hold the strand-wires down ou a line parallel with the guideways in said die F7 and to conduct it properly through the machine.

D is a dividing-plate adjustably secured at its upper end in a box, a', on the cross-bar n, attached to the curved standards K and K, as shown in Figs. 1, 2, and 9. The said box n is provided with the three set-screws 1 2 3, as shown in Figs. 1, 2, and 9, for securing the dividing-plate D therein, and for properly adjusting it with relation to the other parts of the machine. Thelower end of said dividingplate is intended to stand over the two strand- ICO wires between the barb-prods, as shown in Figs. 9,10, 17, '18, i9, and'20, to hold the barbprods separated while the barbbenders are bending them., The lower end of said plate D is shown' in detail in Figs. Sand 20, and shows its lower end recessed, to permit the said forming-die F to move under it, as shown in Fig. 20, and its depending sides, which form the principal divides, are arranged with one side shorter than the other, so the rear prod of a iinished barb may pass under it as the strandwires are taken up on the spool.

A large double-grooved guide sheave-wheel, V', supported between the standards I I, is for the purpose of conducting the strand-wires into the machine, they having passed through guide-holes in `the standard l'. (Shown in Fig. l.) Y are guide-pins supported by crossbar r, between which the strand-wires pass* to hold them in place between said sheaves, and assist in guiding them properly through the machine.

E and E' are a pair of feed-rolls for feeding the barb-wire b' into the machine and for fiattening it, as shown. These rolls are shown in detail in Fig. 22, and are arranged in the housing M, (shown in Figs. l and 2,) the lower roll in permanent boxes and the upper roll in sliding boxes, adjustable vertically, and held adjusted by means of the set-screw X,(show n in said ligures,) to give pressure on the wire between them. The outer end of the shaft of the lower feed-roll is provided with a ratchet-wheel, R2, and has sleeved loosely on it, between said ratchet-wheel and the housing, the ratchet-le ver L', having a wrist bearing the sleeve C'z at its lower end, and a spring-pawl, F', at its upper end tc operate said ratchet-wheel and drive the said feed-rolls. A disk, a3, fixed on driveshaft S2, is provided with a similar wrist bearing the sleeve C, Said sleeves on said wrists are connected by means of the pitman F", having forked heads C and G,that fork,respective ly, over sleeves Cl and C, and hinge thereto by means of screws, as shown in Figs. l and 2,V

thus forming universal joints at each 4end of the said pitman, which is necessary to permit such movement thereof as results from said feed-rolls not being set in a line parallel with the bed B. Said pitman PIl is screw-threaded at each-end for attachment to said forked heads and to regulate their distance apart, and is provided with a set-nut, C, to prevent said pitman from rotating in said heads. The said feed-rolls are rotated intermittently by means of the cranked disk a3, on drive-shaft S2, through the medium of said pitman l, crank L', ratchet-wheel R2, and pawl 1?', and flatten and feedin the barb-wire, each partial rotation feeding in enough wire to form a barb.

M' is a plate having a barb-wire guide for conducting thebarb-wire to the rolls,asshown in Figs. l and 2.

N represents a guide-plate secured to the secondary bed B', and is shown in Figs. l, 2, and 10, and is for the purpose of covering and properly guiding the finished barbed wire from the machine, it having a depending side ylia-nge to prevent the barbed wire from becoming entangled with gear-wheel G, as shown in Fig. l0.

The rotating),` primary barb cutterand bender D (shown in detail in Fig. 6) and the iotating primary bender D:i (shown in conjunction with said cutter and bender D' in Fig. 1S) are each shouldered ou their barb-engaging ends for the purpose of gathering in the prods of the barbs and leaving them standing in a perpendicular position, as shown.

`The secondary rotating barb-benders C and C' are each formed, as shown in detail in Fig. 7, each having, rcsjiectively, a barbengaging shoulder, as shown at c2 in said figure, extending fingers e' and e, for gathering in the barbprods and bringing them to the said rounded barb-bending shoulders, so they may bend the barb-prods down upon the strand-wires, as shown in the process of being so bent in Fig 2l.

The operation ofthe machine is as follows: Commeneing with the two strand-wires XV W'. they are taken from a coil on a reel, passed thence through the guide-holes in standard l', thence once around sheave-whecl V', astrandwire in each groove thereof, thence down be tween the pins Y, and under sheave-wheel V of head H, a strand-wire in each respective groove thereof,lhenee through the guide-channels V' W of forming-die F, in head H, in such manner as to pass over the barb-support F, one on either side ot' its slot. and thence under the guide-plate N out of the machine to a spooler and twister and a take-up. rlhe barbing-wireb is taken from its coil on a reel, )assed through the guideM' of housing M, thence through between the feed-rolls E E', where it is flattened by the rolling pressure of said rolls, thence into and through' the curved guide R, to and between the cutter l)2 and cutter and bender D'in adiagonul course,and thence under the strand-wires Wv \V and upon the barb-support F', immediately at the sideof its hooks 71 and over its slot 11.', inadiagonal position, as shown in Figs. 4- and 1S. The parts of the machine are so timed that when the barb is thus located the forming-die F has moved forward over the barb and upon the support F in such man ner that its bottom channel rests exactly over the central part ot' the barbs body, as shown in Fig. 20. At this instant punch l? is moved up through slot h.' of support F', and forces the body of the barb up into the bottoni channel of forming-die F, thus forming the central U -shaped bend in the barb. The barbis then instantly severed from the barbing-wire b' by the rotary action of cutter and bender D', shearing with stationary cutter D2, and the two barbprods are then respectively bent from their horizontal position up to aperpendicular position, one on each side of the forming-die F and strandwires W V, by the engagement with the barb-prods of said cutter' and bender D' and oppositely-rotating bender D, and in such manner that the dividing-plate D will be directly over the een ico IIO

tral U-shaped bend of the barb and between its prods, to prevent said prods from leaning sidewise when the formingdie F changes its positio1i,wl1ich takes place immediately alter the prods receive their primary bend, as shown in Figs. 17 and 20, and by this reversed position of forming die F on its backward movement lowers the strand-wires NV \V into the hollows of the barb caused by its bends, one on either side of its central U-shaped bend, to the position shown in Figs. 16 and 19. At the instant the forming-die Fhas receded, the secondary or finishing oppositely v rotating YVbarb-benders C and G' have rotated to cnraoe the barbprodaone atcach side of divider D, in such manner that the said prods, if not in eXact position, may be gathered into their properposition so the rounded shoulders of said benderswill engage them and bend them from their perpendicular position to a horizontal position upon the strand-wires V XV, so their prods will point in opposite directions and be clamped upon the said strand-wires and carried on out of the machine by their frictional contact with the strand-wires, which move continuously through the machine as they are taken up by a spooler and twister. im mediately upon the completion of a barb, as described, the feeding mechanism feeds forward enough wire for the next succeeding barb,which is cut and formed in like manner. As the finished barbs pass under the guideplate N their prods engage therewith, and thereby prevent the strand-wires from being cabled by the twister until they leave said guide N. The cam Z, which operates punch YP is formed as shown in Fig. 13, and is so set and timed with the other mechanisms of the machine that the eccentricportion of its channel from line 1 to line 2 has caused its frictionroll Z2 to move near the center of the cam, and thus draw on pitman P, which oscillates head Ff, to move up said punch, as stated, and as the said friction-roller in the cam passes from line 2 to line 3, which is a very short space, said roller is quickly moved from the center of the cam a very little, which will permit the said punch to be slightly lowered sufiicient to relieve all pressure on the barb, but,v

not to be withdrawn from the U-shapcd bend, and the said punch remains with the barb to assist in its proper support until it is finished, and during that time t'rictioirroller Z2 travels the cam-channel from line 3 to line 4. Vhen said cam has completed its revolution, the friction-roller Z2 has passed again into that part of the cam-channel between lines 4 and 1, to withdraw punch l? until a new barb is fed in,'so another like opera-tion may be performed. By this construction and arrangement the parts of ihemachine that act directly upon the barbs to bend their prods rotate continuously and very rapidly, so they attach the barb-prods to the strand-wires much more nicely than when they are bent slowly, and form them more accurately.

The finished product of the machine, as

shown in Fig. 23, consists of what is termed a two -strand two pointed wire barb, the barb being formed from a short piece of flattened wire pointed at each end, having a central U-shapcd bend placed transversely between the strand-wires, so as to form a springsupport to the strand-wires, and having its prods bent in opposite directions to clasp each strand-wire and point in opposite directions from each other, as shown in said figure.
