BARB-WIRE MACHINE.

SPECIFICATION forming' part of Letters Patent No. 270,645, dated January`.16, 1883K Application filed November 1, 1882. (No model.)

T0 all whom it may concern:

Be it known that we, WILLIAM EDENBORN and (UsrAv GRIEsoHE, both of the. city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement .in W'ire-Barbing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanyin g drawings,forming part of this specification, and in which- Figure l isa top viewof the front end of the machine. Fig. 2 is a side elevation of same, showing part of the supporting-legs broken away. Fig. 3 is a front end view of same with vlegs broken off. Fig. 4 is a Vertical transverse section taken on line 4 4., Fig. 1. Fig. 5 is,

a transverse section taken on line 5 5, Fig. 1, enlarged. Fig. 6 is a similar view taken on line 6 6, Fig. 1. Fig. 7 is an end view of the barb-former, showing its position before making the bend. Fig. 8 is'a similar view after the barb is formed. Fig. 9 is a detail longitudinal section of same, taken on line 9 9, Fig. 7. Fig. 10 is a similar view taken on line 10 10, Fig. 8. Fig. 11 is a detail enlarged perspective view of the barb-forrner, showing the finger in its outer position. Fig. 12 is a simi-' lar view, showing the finger in its inner position. Fig. 13 is an enlarged' perspective view of the shears or cutters, showing their position just before cutting the Wire. Fig.14 is a similar view, showing their position just after cutting. Fig. 15 is an enlarged top view of the clamp forl feedin g the barb-wire inward toward the main wire, showing the clamping-jaws open, which is 'their position as the clamp moves outward. Fig. 16 is a similar view, showingthejaws closed upon the Wire, which is their position as the clamp moves inward. Figs. 17 and 18 are diagrams showing in side elevation and in different positions the device for carrying the wires forward in such a manner that while they are fed continuously to the spooling, anparatus, yet they are allowed to remain still, forward of this point, at intervals of sufficient length to have the harbs applied. Fig. -19 is a perspective view of a piece of the barb-fencin g.

This invention relates toa machine for putting barbs aternately-that is, first putting a barb on one of the wires and then on the other-on the two wires, which are subse- 'qilently twisted together in the usual manner' of novelty hereinafter fully described and' claimed.

Referring to the drawings, A represents the table of the machine, and AI the snpportinglegs.

B represents the main shaft of the machine, journaled in boxes B1, secnred to the table. On onel end of .the shaft B (not shownywould be a driving-puiley, and this end of the shaft would connect, by means of suitable gearing, with the spooling apparatus. We have shown these parts, which are of common well-known construction, in another application of even date herewith.A On the other end of the shaft B is a cog-wheel, O, which engages with a pinion, O', on a hollow shaft, C2, of one of the barb-formers, which is journaledjn suitable boXes, O3, secured to the frame A. The pinion O' engages with a similar pinion, D, on a hollow shaft, D', similar to that 02, whichis jour- ,naled in boxes D3, secured to the table. In Fig. 1 the tops of the boXes D3, are removed and the shaft D' is shown in section. The pin- E', working in boXes E2, resting upon and secured to the tableA. One Wire passes through shaft O2, the other through shaft D'.

As the two barbing devices and their accompanying parts are exactly alike, it will only be necessary for us to describe one of them, the same letters of reference referrin g to the other.

The shaft D', and of course that 02 also, is made of different diameters, being considerably the largest at its forward end, where'it is channeled to receive the forming-finger F', which has a pin, F2, on its outer end. After inserting the fin ger the channel is closed above it by a dovetailed piece, F3, which holds the finger in place. This' end of the shaft is also bored out. to receive a bushing, G,which has 80 ion D engages with a cog-wheel, E, on a shaft,

a conical outer end, (see Figs. 11 and/12,) for i the purpose hereinafter explained, and it has a central opening through which the wire passes; As the finger finishes the formation of the barb it has an endwise motion imparted IOO to it, which causes it to recede into the hollow shaft, out of contact With the barb-wire, while the shaft continues to revolve, and immediately after it recedes it is thrnst forward again to its outer position, ready to form another, the main Wire in the meantime having been moved forward the desired distance, as hereinafter described. This reciprocating motion is given to the finger by the following means z H is a collar fitting loosely over the reduced or sinaller portion of the shaft D', and is connected with the finger by means of a set-screw, H', (see Figs. 1 and 5,) or by other suitable means. The collar is grooved to receive an annular ring or band, Hz, to which the arms J' of one end of a lever, J, are secured. The lever is fnlcrumed to a post, J, secured to the frame A, and its other end works in a groove, J, of a collar, Jg, secured to the end of the shaft E'. The corresponding collarot' the other side of the machine is on the end of the shaft B. The outer Wallof the grooveZIis provided with a projection, J, and the inner wall with a corresponding notch, JS, (see Fig. 1,) which, coming in contact with the end of the lever, moves the collar H outward, as shown on one side of the machine in Fig. 1, caus'ing the pro- -jecting part of the finger to recede into the shaft, as stated, and then, as the projection leaves the end of the lever, it (the lever) is moved to its other position, throwing the tin ger to its working position. It will thus be seen that the fingers have continual revolving and intermi ttcnt reciprocating motionsimparted to them.

We will now describe the devices for interinittently feeding the wires from which the barbs are cut.

L is a block working in a suitable groove in the top of the table. The groove admits of an end-play of the block, and is lettered L'.

L2 Lll are jaws pivoted to the top of the block L, as shown, and having their rear ends so formed that a V-shaped opening is left between them. The'jaws Where they bear upon the wire are notched or serrated.

M represents a wedge, which rests and has capacity for a limited end movement on the block L, its inner end fitting between the rear ends of the jaws. The top of 'the block is formed with a flange around the outside, forming a cup in which the jaws and wedge fit.

Nis a lever pivoted at NI to the top of the table, and connected at one end by means of an arm or link, N, to the wedge M. The other end of this arm is connected by means ofa link, Ni, to one end of another lever, 0, which is pivoted at O' to the table, and which has on its other end a friction-roller, O2, which bears against an cccentric, O, on the shaft W. The correspondng roller on the other side of the machine bears against an eccentric on` the shaft B. With this connection between the sliding blocks L and the shafts E' and B it will be seen that the former will be moved inward each time the salient parts of the ec centries bear against the friction-rollers, the wedges 4first being moved inward, as they connect with the arms, as described, pressing the notched faces of thejaws against the wires, which pass between them, as shown in Figs. 15 and 16, and thus the wires are moved toward the main wires With the blocks the necessary distance to give Wire enough for the barbs, and the eccentrics are so located on their shal'ts that they will act alternately on the levers, so that one places a barb on its Wire and then the other, a. barb on the Wire passing through its hollow. shaft, and so on, the principal advantage being rapidity in work, for as the two are working at the same time, and each only having to do half the work, the main Wire can be passed through twice as fast as when it has got to wait for one device to apply all the barbs. The spooling apparatus would of course have to be geared sufliciently high to take up the Wire. The projeetions J* on the collars JJ are so located as to act on their respective arms or levers J in eonformity with the action of their levers N O.

The wires from which the barbs are cut pass through the flanges of the ends of the blocks and through the wedges, as shown in Fig. 15, between the jaws. When the blocks have been moved inward, as described, the salient parts of the eccentries O3 are of sufficient length to hold them there until the fingers have given the barb-wires with which they then come in contact one bend around the main wires, and then the eccentrics suddenly leave the arms, and suitable Springs, O4, bearing against the levers N, (see Fig. 1,) force the wedges outward against the rear flanges of the blocks, which loosens the clamps upon the wires, and then, as the wedges cannot move outward farther on the blocks, the blocks themselves are carriedoutward, the wires slipping through them, for, as before stated, they have'been madefast to themain wires.

We prefer to place springs P l) between the side fianges of the block and the rear ends of the jaws, (see Figs.15 and 16,) which take the bearing of the grasping ends of the jaws from the Wire as soon as the wedge has been forced outward; but these Springs are not absolutely necessary, as the jaws would slip over the Wire without them, though they would bear slightly against it.

The ends of the levers N and 0 are adjustably connected together, preferably by means of the bolts securing the link N3 thereto passing through slots E205. (See Fig.1.) This adjnstable connection gives means for changing the movement of the block, and consequently the amount of Wire fed at each-operation. The barb-wire passes beneath the main Wire at or near right angles thereto, and the finger, coming against its free end from beneath, bends it around the main wire twice, as shown in Fig. 10, and then retreats into the hollow shaft, as before described.

Inimediately after the.

IlO

'fore the 'knife Q3 descends.

block L has made its return movement, which takes place when the finger has bent the barbwire around the main wire once, and whilethe finger is completing its work, the barb is cut i from the main body of the-Wire by knives constrncted as follows:

Q is an inclined lever pivoted to a post, Q', by means of a bolt passing through a hole, Q2, in the lever. The post' is secured to the top of the table. To the lower end of the lever (see Figs. 13 and 14) are secured a knife, Q3, and a guide-block, Q4. The barb-Wire passes through this guide-block, and may also, as shown, pass through the lower end of the knife, (see dotted lines, Figs. 13 and 14,) and the knife has a beveled edge, which works against the beveled end of a stationaryknife, R, secured to the table A by means of a plate, R1, or by other suitable means. The hole in the 'guide-block and the knife through which the Wire passes is so located that the Wire will come out through the bevel-edge of the knife Q3. This knife has an intermittent'circular motion imparted to it by means of the upper end of the pivoted lever extending over the shaft E' and being struck by an eccentric cam, S, (see Fig.- 1,) on the shaft El. As the cam strikes the lever it lowers' the end to which the knife is attached, imparting the said circular motion to the knife by the lever turning on its pivot, which carries the Wire down upon the stationary knife, cutting the barb, giving to it the desired sharp point. The knife Q3 lworks in the space Q5 (see Figs. 9 and 10) between the end of the hollow shaft D' and the stationary knife R. To force the Wire over the stationaryknife (see Fig. 10) the conical end of the bushing G, before mentioned, is employed. As the finger Wraps the barb-Wire around the main Wire twice, and as there is only room enough for one bend ofthe Wire between it when in its normal position and the end of the bushing, it will be seen that the second bend will move the first bend forward by wedging between it and the inclined end of the bushing, forcing the Wire over the stationary knife be- Not only does the bushing 'force the Wire over the knife R, but by this lateral movement binds it in the opening of the knife Q3 or the guide-block, thereby enabling the knife to cut it more easily.

As soon as the cam S operates the lever it leaves it, and the upper end of the lever is thrown down, thereby raising the knife Q3 by means of its own Weight, assisted by a spring, Q6, secured to the upper end of the post Q', and bearing against a projection, Q7, on the upper end of the'lever. (See Fig. 1.) In order that the lever Will not bear or be'pressed upon the shaft B by the spring Q6, we secure an arm, Q9, to the end of the lever or to the projection Q1, which, when the lever is not raised by the cam S, rests upon the table, as shown in Fig. 2, holding the lever up out of contact with the shaft. As soon as the fingers have completed the barbs and the knives cut them ofl', theV main wires are carried forward theproper distance by mechahism which we will now describe. I

The wire from the barbing device passes over a wheel one of course for each Wire-T and beneath a single wheel, T', from where they pass to the spooling apparatus over a single vibrating wheel, as nsual. The top of the Wheel T works through a slot, T2, of the table,

.to so arrange these Wheels that the wire will be fed' to the spool continuously, while in advance of the wheelsit is allowed to stand still at intervals of sufficient length to have the barbs applied, we secure the wheel T' to a' shaft, U, which is journaled in suitable boxes, U',suspended,byhangersU2,beneath thetable. Power is applied to this shaft preferably by means of a cog-wheel, U3, thereon 'engaging with a worm, U4, on a shaft, U5, journaled in boxes U6, suspended from the bottom of the .table by hangers U7. On one end of the shaft Uis apinion,U8, engaged byacog-wheel,U9, on o'ne end of a'shaft, U10, journaled in boxes U11, suspended beneath the table by hangers U12. On the other end of this shaft U10 is a cog-wheel, U13, similar to that, U9, which engages with the wheel O on the main drivingshaft B. Thus the wheel T', which carries the main wires for- Ward, is driven-from the main shaft of the machine. The wheelT isjournaled in a short axle, V, on the upper end of an arm, V', supported by the shaft U. (See Figs.3 and 4.) The arm V'is connected by a suitable link, V2, to the lower portion of a lever, V3, which is pivoted to the table A, through which it passes at Vt, and whose upper end has a lateral projecting pin, V5, which Works in a groove, V6, of a collar, V1, secured to the shaft Ef, the duplicate collar on the other side of the machine being on the shaft B, as shown. The groove passes spirally around the collar until it has about surrounded it, and then with a sharp change passes inthe other direction, as shown on one side of the top view, Fig. 1. As the pin works in this groove it will be seen that the lower end of the lever V3 will be gradually moved toward the front end of the machine, carrying the wheelT with it, and then when the pin comes to the change to the direction of the groove the lower end of the lever and wheel will be forced with a quick movement in the other direction-that is, away from the front end of the'machine' Themachine has its parts so arranged `that this quick forward movement of the wheel T occurs just after each barb has been attached and cut off, and it carries enough of the main IOO IIO

wire forward to bring the next barb in the proper place. Then as the wheel moves slowly backward the spool takes up the slack beneath. The wheels T of course act alternately in con` formity with their respective parts.

Ve prefer to assist the quick forward movement of the wheel T by a spring, W, connecting the upper end of the arm V' back of the wheel with the bottom of the table. The arm V' and the lower end of the lever V3 are adjustably connected by the bolts securing the link V2 thereto passing through slots V, as shown in Figs. 2, 17, and 18.

VVe do not claim broadly in this application the mechanism for moving the main wires forward, nor the mechanism for feeding t-hebarbwires, nor the mechanism forcutting the barbs off, as they form the subject-matter ofour other application above mentioned; but

\Vhat we do claim in this application,and desire to secure by Letters Patent, is-

In a wire-barbing machine, the combination of (luplicate revolving hollow shafts, through which the main wirespass respectively, duplicate barb-forming fingers within said hollow shafts, duplicate collars and levers connecting said fiugers with operating-shafts, whereby the fingers get a reciprocating motion, duplicate sliding blocks carrying clamping-jaws, and wedges operated through means of levers connecting them with ecoentrics on the main shaft, and duplicate wheels over which the main wires pass, which have capability for movement in the direction of the travel of the main wires, and means for Operating them from the shafts of the machine, and connected means for Operating the said parts alternately, substantially as and for the purpose set forth, the two wires passing from the duplicate vibrating wheels onto a single wheel to which power is applied, as described and shown.
