Fig. 8 is a vertical cross-sectional view of the machine on line-2 of Fig. 1, looking in the direction of the arrow. Fig. 9 is a vertical cross-sectional view of the machine on line 3 of Fig. 1, looking in the direction of the arrow, showing a side view of the barb-compressing mechanism. Figs. 10, 11, 12, 13, and 14 are detailed views of the barb bending and folding mechanism, showing the barb in the various stages of formation, and Fig. 15 is a view ofa section of a pair of strand-wires having a barb applied thereon, being a'production of this machine.

Referring to the drawings, B represents the principal bed of the machine, intended to be supported on suitable legs, and B is a second.- ary bed or plate, secured to the upper face of bed B, for supporting the barb bending, folding, and cutting mechanism.

S is'the main shaft,arranged. above and along one side of bed B in the standard-boxes B B, and has keyed on it sprocket-wheel m, to which power is applied to drive said shaft, cams C, O, and O, eccentrics O E, crank-disk D, and mitergear e.

A is a stationary barb-point cutter, secured in a standard-box on bed B by means of capplate H and 011 a line with the space between the strand-wires.

A is an oscillating barbpoint cutter, arranged. to shear with stationary cutter A, and is secured by means of cap-plate F to the upper side of lever F, fulcrumed at Z between standard lugs d d, and connected at its opposite end, through the medium of an-eccentric strap,with eccentric E on shaft S, by means of which said lever and its cutter A is oscillated. (See Figs. 1 and 5.)

H is a lever fulcrumed near its center at Z, between a pair of standard-lugs, d d, on bed B, and having its rear end provided with a roller-wrist, A, for-operating in the channel of cam O, and its opposite end having a chamber for holding the strandwire guides adapted to be adj ustably held thereon by set-screws. (See Figs. 1, 2, and 5.) The said strand-wire guide consists of the sleeve I, for containing the centert, provided with oppositelongitudinal channels, and the center 15', having a pair of longi tudinal holes corresponding with the channels in center t, through whichchannels and holes the strandwires W are threaded. (See Figs. 2,4, and 8.) These centers tand t are secured within said sleeve by set-screws.

It and R are a pair of reciprocating barbprod benders arranged in box D and held therein by means of the cap-plate D D is a rock-shaft arranged in an extending box of cap D and has on its inner end a disk, K, provided on its face with a pair of opposite pins,f and f, respectively connected to the reciprocating barbbenders R R. (See Figs. 6 and 7.) The barb-benderR is provided with an opening, as shown in Fig. 7, for the purpose of permittingpinf to pass through it to connect with the opposite barb-bender, It, and so barb-bender R can reciprocate. The opposite end of shaft 1) is provided with crank L, having a roller-wrist for operating in the channel ofeam C. The form of said eam-ehan nel is such that said shaft D is intermittingly rocked when said cam rotates, and through its connection with the barb-benders R It will reciprocate them in opposite directions, for the purpose hereinafter described.

S is a rock shaft secured in a box on bed B, and has secured on its outer end the arm L, for engaging cam C on shaft S, and has secured on its inner end the oscillating barb-prod'bending arm R".

S is aspring for holding arm L engaged with cam 0-. (See Figs. 2 and 8.) \Vhen said cam rotates, the barbprodbending arm It will be intermittingly oscillated, for the purpose hereinafter stated.

N N are a pair of ordinary barb-wirefeed rolls having their shafts geared together and intermittingly driven by shaft S, through the medium of crank-disk D, pitman l and a pawl-and-ratchet mechanism, in the ordinary manner, (see Fig. 1,) and r is a guide for conducting the barb-wire from said rolls between the strand-wires and cutters.

J and J arejaws forming a press for compressing the barbs properly on the strandwires after they have been folded thereon by the barb-benders. The jaw J is stationarily fixed on bed B and jaw J" is hinged to jaw J at its foot and rests at its upper rear side against eccentric C on shaft S, by means of which it is oscillated to open and close said jaws.

C is a curved spring secured to the upper side ofjaw J, and extends over said eccentric for the purpose of holding jaw J in engagement with said eccentric O.

J and J are removable interchangeable plates secured respectively to the inner face of said jaws and have their faces concaved, so when they compress a barb they will bring its prods and strand-wires in line with each other, (see Figs. 1 and 9,) or nearly so.

V is a barb-point guide secured to the body of the reciprocating barb-bender R, in a suitable recess between the benders R 1%, and is formed, as is shown in Figs. 4, S, and 10, so it will guide the barb prod properly between the benders 1% R and over the grooved lugs 0 thereof. (See Figs. & and S.)

The reciprocating barb-prod benders R R are formed in such manner that each has a depending arm overreaching the strand-wire line of the machine, (see Fig. 8,) and are respectively provided at the lower end on their sides facing each other with circular grooved lugs O and O, as shown in Figs. 8, 4, 8,10, 11, 12, 13, for engaging the barb-prods to assist to fold them on the strand-wires.

V is a presser-foot secured to lever II by means of standard V" and arm V, as shown in Figs. 1. and 2, and is for the purpose of pressing 011 the strandwires to hold them in line with their guide when the strand-wire guide is descending. g is an outer guide or eyelet through which the barb-wire is guided to the feed-rolls.

The two reciprocating barb-prod benders R and it have their outer extending ends constructed, as shown, to form depending arms having the circular grooved lugs O and 0 respectively secured to them on their sides facing each other and at their lower extremity, and are adapted to reciprocate only when the strand-wire guide has descended to be below them.

The lugs O O are not relieved from contact with the barb-prods until they are completely folded on the straml-wires and operate as a rest for the prods to lie against while the strand-wire guide is ascending and descending between them, and they change position with each other whenthe strand-wire guide is out from between them to fold the prods over in opposite direction on the strand-wires.

In this machine the principal new features are in the parts that fold the barb on the stranttwires, and consist of an oscillating strand-wire guide for elevating and lowering the strand-wires during the process of folding the barbs thereon; of a pair of oppositely-reciprocating barb-prod benders arranged one on either side of the strandavircs at the place the barb is fed between the said strands, and in such manner as to engage and support a prod on either side of the strand-wires after being severed. from the barb-wire, and while the strand wire guide descends and bends the two prods up they then reciprocate in opposite directions and fold the two barbprods over the upper strand-wire, so they project in a horizontal plane in opposite directions and hold the prods while the strandwire guide ascends and bends the two prods to project downward; of an oscillating benderarm for engaging one of the downwardly-pro, jeeting barb-prods and bending it laterally under the lower strand-wire and support it until the strand-wire guide descends again, which will bend said prod upward to project in an opposite direction from the opposite prod, thus completing the fold of the barb upon the two strand-wires, after which the strand-wire guides further descend, so that the two barb-prod benders can reciprocate back to their first position, and the strand wires are drawn along to carry the said barb along out of the way, so the next succeeding barb can be applied.

In operation the two strand-wires \V \V are taken from the coil, passed over a suitable guide in the ordinary manner, thence they are threaded through the center guides, t and 25, between the barb-prod benders, between the barb-compressing jaws, and thence to and over an ordinary oscillating sprocket-wheel,

T, to a spooler and twister below the barbing mechanism, (not necessary to be shown, as it forms no part of this invention,) and so that one wire will be directly above the other, as shown in Fig. 2 particularly, and are intermittingly drawn through the machine by means of said sprocket-wheel T, inthe ordinary manner. The barb-wire is fed through the guide g by means of the feed-rolls N N, so as to enter between the two strand-wires and between the two reciprocating barb-benders R R, and when first fed inisin the position shown in Figs. 4 and 8, the barb lying over and in the grooves of the lugs O and 0. Further rotation of the machine will cause the strand-wire guide I t t and strand-wires \V therein to de scend from the position shown in Fig. 8 to that shown in Fig. 10, the cutters A A severing.

the barb from the barb-wire at the same in stant. WVhile the barb is in'the position shown in Fig. 10 the reciprocating barb-prod benders reciprocate and change position with each other to that shown in Fig. 11, thus folding the barb on the upper strand-wire. The strandwire guides, with the strand-wires, then ascend between the benders R R to the position shown in Fig. 12, causing the benders to bend the two barb-prods downward, one prod, W, being longer than the other. The arm R then moves forward and engages the long prod IV and bends it to the position shown in Fig. 13. The strand-wireguide and strand-wires then descend and cause the arm R to bend prod W upward, as shown in Fig. 14, and sothat it incloses the lower strand-wire and projects in the opposite direction from the other prod, and at the same time the two barb-benders R R reciprocate and change position back to that shown in Figs. 4 and 8, finishing bending and folding the barb on the strand-wires.

The upper end of arm R is provided'with a notch, h, for engaging said barb-prod, andis cutaway at the side of said notch, as shown in Fig. 2, so as not to engage the opposite prod. After the barb has passed through said various stages, and is formed as shown in Fig. 14, the strand-wires are drawn along by means of a .tak'e-u p mechanism, (not necessary to be shown,) and the barb thus formed passes between jaws J J, which compress it on the strandwires'in the proper form, and leaves it finished and applied to the strand-wires, as shown in Fig. 15. i

Having thus described my inveutiomwhatI claim as new, and desire to secure by Letters Patent, is as follows, to wit:
