View of the coiling-shaft set in its boxes and having its reciprocating lever attached.

This machine is for the purpose of manufacturing barbed wire for fencing purposes, such as is shown in Fig. 12, formed of a single strand-wire having crimps at suitable intervals along its length, and having short pieces of wire, pointed at eachend, coiled on the said crimps for barbs, as shown. in said figure.

For the construction and operation of said machine, reference is had to the accompanying drawings, in which a general side elevation is shown in Fig. 1 and a plan view on the top shown in Fig. 2, and the other figures illustrate different parts and views of said figures to render them more readily understood;

The working parts of the machine are supported on the main frame A, which stands on the legs A. A centrally-located cross-shaft, S, (shown particularly in Fig. 2,) bears the main drive-pulley B2 on its outer end, to which the dies in the form shown in Fig. 12.

power is applied, and has attached to it all the cams and cranks that drive the various parts of the machine. Asprocket-wheel, d', is attached to the opposite end of said shaft S, and by means of the sprocket chain d2 drives the sprocket-wheeld3 onthe hollow shaft S, upon which the spool W* is placed to spool the iinishcd barbed wire.

Through the hollow shaft S2 passes the square shaft S through asquare opening at the sprocket-wheel end, so that the said square shaft will S drives sprocket-wheel h on shaft a* by means of the sprocket-chain h2, to drive the wheel a, that rotates intermittingly the coilinghead H3 by means of its meshing with the pinion m on the part of coiling-shaftmarked F2, as shown in Fig. 11. The crank Fon shaft Sis connected by the pitman P to the sliding head K, (shown more particularly in Fig. 7,) to reciprocate the feedjaws c and c. that grasp the strand-wire W' between the dies 'o ando and feed it forward into the machine, andat the 'same time crimp the wire between said The waved cam-wheel H7 on the shaft S operates the die Z', which, in connection with the stationary die Z, cuts off the barbing-wire as it is fed in between said dies, as. shown in Fig. 5. The

'die Z' is set in the head H, which is pivoted `in the frame H2 by the bolt @Zand which head Hterminates in the tail-piece H, having at its outer end, on the under sideya pair of wristpins and friction-rollers, (shown by the dotted lines in Fig. 2,) between which the waved cam Hlrotates to vibrate said tail-piece horizontally to operate said die Z. The cam DT on 4shaft S operates the feed device that feeds the ,barb-wire tinto the machine.

The waved This feed de-- IOO pivoted at the foot in the hanger D.

lever' D.

These two armsare Yconnected at the top by means of the link D2 and bent lever D', having the set-screw n4 in its outer end. The armD has its upper end terminate in an elbow to sustain the upper set-screw, a5, directly over set-screw n, between which set-screws the barb-wire t passes and is grasped to be fed forward. As cam D7 rotates between the wrist-rollers Dt,- the upper end of arm D5 oscillates backward and forward, and by its connection with arm D oscillates that inthe same manner. As they move forward toward the machine, they cause the two set-screw dies at a5 tograsp the wire t and drive it forward. The set-screw a passes loosely through an opening through' arm" D andthen screws into the lower side of Vhen arm D5 moves backward, it will' carry with itk arm'D as soon asthe head of'set'screw n comes up in contact with arm D. When set-screw a3 is screwed outl to its full length, arm D5 will move some distance before it will move arm D, and then move it only a" short distance, and consequently shorten the stroke of said arm'D and the feed-dies at a5. A longer stroke and feed will be obtainedby turning set-screw 21? in, the length of the stroke of the feed being thus regulated by turning saidy set-screw in or out. Thewire thus fed in forms the barb. The wire is prewhich'is a square rod that passes through aV square opening through the length of the shaftS2,which rotates in boxes in the frame A3. When it is desired to place a spool, WV, on

vthe shaft S3, the shaft S is withdrawn, and then passed back through the shaft SZ and thespool W4, as shown in Fig. 2. The sprocket-chain d2 travels or' rotates continuously and drives continuously the sprocket-wheel d3 on shaft S2, on which it loosely rotates. The spool can only rotate intermittently to windon it the finished wire, as the strand-wire must stop anv instant each time a barb is placed on it, and for that reason the spool must stop long enough to permit the barb to be placed on, and then rotate sufficiently to take up the wire until it is necessary to stop it to place another barb on it. In order toaccomplish this, the sprocketwheel di on shaft Sz is placed between two friction plates or disks, g and g, the disk g being keyed to the shaft S2, so that when it rotates it will rotate the said shaft with it. The outer end of shaft S2 is threaded, and a nut, g3, having arms by means of which it can bel turned, is placed thereon, and between said nut and disk g is placed a rubber collar, g2, and washer g4, so that when the `nut g3 is turned up against said rubber collar it will cause the two disks g and g to clamp the sprocket-wheel between them, rand clamp it with sufficient force so it will by frictional Contact rotate with them. Disk gbeing keyed to S2, rotates that with it, and also the square spool-shaft S', upon which the spool is placed.

The frictional contact of the disks g and g is not so'greatbut that t-he barbing part of the machine may hold the strand-wire still an instant to place on the barb but it is intended the strandwire will only pass through the ma chine intermittingly as fed in by the reciprocating feed c and c', and that the friction on sprocketwheel d will not overcome the tension on the said strand-wire at the Yopposite end of the machine, where it passes between the straightening-jaws cl0 cz, so that by this means the spool mayirotate intermittently to between which one of the arms of the spool lies, andisheldtherein by alatch, Sl. (Shown in Fig. 9'.) Aswitch, S5, attached to said head S, runs in the screw S4 and causes thc spool to traverse said screw-shaft back and forth, for the purpose stated. A

rIhe operation of the machine is substantially as follows: The strand-wire XV enters the' machine at the left, looking at Figs. l and 2, and travels forward in the direction of the arrow. It first passes between a pair of die plates, c0 cl2, between which it draws to give tensioa to the wire as it is drawn through, and also to straighten out any kinks or bends there may be in it. The upper die-plate, c1", is set in the arm y, pivoted at its inner end on thev frame c, which is partially supported by the brace c?, while its outer end is held down by the coil-spring i', so as to cause the dieplate c10 to press firmly on the strand-wire; The spring fz/ may be adjusted by means ofthe sliding plate y2 to give more or less tension on the arm y. A weight, instead of said spring, would answer the purpose as well. The wire W next passes into the feed, (shown more particularly in Fig. 7 consisting ofthe reciprocating head c and bell-crank jaw c', furnished with a pair of dies, o and o', regulated by the set-screws c2 c, and having their meeting faces formed so that when they grasp the wire they will form a bend or crimp in it, such as is shown iu Fig. 12. This reciprocating head is driven by the crank P and pitman P and traverses in the ways c of. (Shown in Fig. 8.) The head c is divided, as shown in its rear in Fig. 8, so thebell-crank jaw c can be pivoted between its two parts, as shown, and its lower end hang down so as to lbe between the set-screw IOO IIO

forward,it will cause the stop ZL to press againstr the lower end of the bell-crank jaw c and byv `Z3 and the'stop Z* made adj ust'ableby the set` screw Z5. The stop Z* and set-screw Z3 are attached to ahead, K, which reciprocates in ways within said reciprocating head c, and to which head the' pitman l? is attached, as shown in -When the pitman moves the head that means move the sliding head o forward. A. reverse motion causes the set-screw Z3 to come in contact with said jaw, and thus move the head c backward. The set-screws Z3 and Z5, regulate the distance the head c is to reciprecate, and thusregulate the distance apart the barbs are to be placed. A forward movement ofthe reciprocating head c causes the -wireW to be graspedbetween the dies o and o and crimped and carried forward into the stem H, which is provided with a channel its entire length.` to conduct the wire and hold the crimp right side up or vertical at the place where the barb is placed on. rlhis stem H6 is shown in cross-section in Fig. 10, and extends entirely through the coiling-shaft H, of which Fig. 1l is an enlarged side View, and is also shown in Figs. and '4. The part F2 is the part upon which the pinion m, Fig. 3, is firmly keyed. The remaining portion between said pinion and the enlarged head end H3 is inclosed within a box7 R, and is jointed together, as shown in Fig. 11, so the large end H3 'may be reciprocated horizontally by means of the saddle w", pivoted to the ears H* on the opposite side of the annular ring H5, that lies and turnsin a corresponding annular channel in the ceiling-head H3. This saddle attaches vto the lower end of lever aT, pivoted near its center in the frame of the machine, while its upper end is provided with a roller-wrist t-hat runs in the cam-channel a of cam a, as shown in Fig. 8. This arrangement will give a reciprocating motion to the part F of said coiling-shaft, and the head part H3, having` the ceiling-hook i) on its outer end, so that when the coiling-hook 'u begins to coil the barb on the strand-wire it will coil as it recedes, and thus give a long coil to the barb to make it coverthe entire crimp in the strand-wire, as`

shown in Figs. 3, 11,'and l2, instead of coiling it all on in one place, as it would do -if the coiling-pinion did not reciprocate. The stem HG, as before stated, passes through the whole length of the ceiling-shaft, and is held stationary in the box a, as shown in Figs. 2 and 3, so it will not rotate or get out of place, and thus form a stationary permanent conductor of the wire W up to thecoiling-hook c. The coiling-head H3 rotates in one direction intermittingly, and only rotates when a barb is to be coiled on. Each feed ofthe strand-wire delivers a part ofthe strand-wireVmhere it is crimped directly under the coiling-hook n, as shown in Figs. 3 and 11, and at the same instant the barbwire tis fed in far enough bythe barb-feed (described and shown in Figf) to make a single barb, and at the outer end of the crimp in the strand-wire from the coiling-hook o. The coiling-headH3 and the shaft it is attached to then begin to rotate by means of the teeth m on the pinion m running in the cam-channels a2 on the face of the cam-wheel a, which causes the coiling-hook o to catch the fed-in end of the barb and coil it on the strand-wire WV on one of its-crimps in the form shown in Fig. 12. The coiling-shaft then stops its rotationby means of one of the teeth of the pinion m having run into the groove a on the face of the said cam-wheel. As soon as the ceiling on of the barb is finished, a wave in cam-wheel H7 moves the tail-piece H and head H, containing the cutting-olf die Z', Fig. 5, and cuts oft' the barb from the barb-wire in a diagonal direction, to leave sharp ends for prods. Vhen the head c and jaw c move forwardthe spool takes up as much finished wire as is so fed forward by the said headc and jaw c. While the barb is being so coiled on the strand-wire,

the reciprocating head c returns to perform another like operation. Aftera barb has thus been placed on the strand-wire,it passes under ay press to cause the prods of the barb to point in the proper direction and to straighten them. This press is shown in Figs. l and 7, and consists ofthe arm B, pivoted at B6 to the standard H2, while its other downwardly-extending end is provided with a roller-wrist, to run in the cam-channel of cam-wheel B. The arm B is furnished with the adjustable die B2, regulated vertically by the set-screw B. v The form of the cam-channel in cam-wheel BT will cause d'ie R'l to descend on a barb just at the time it passes under the said die to perform said service.

B is a bed-plate, over which the wire V passes, and between which and said die R2 the barb is so pressed. -Wlien it ascends, Vit permits the barb to pass on. 'The finished barbed wire then passes onto the spool WV", over the shoe-guide NVE, which is attached to the outer end ofthe spring-arm WV?, which is for the purpose of preventing a sudden jerk or jar tothe spool. As the friction plates or disks heretofore described rotate the spool, it draws down on the spring-arm NVS, which will givea strain to the wire lV, and, as said wire is fed forward, said spring will ease the-'starting of the spool. The barbing-wire t, after it leaves jaws n and a", Fig. 5, passes into thetube t, which guides the wire into the cutting-oft' dies Z and Z. The reciprocating head c is provided with a roller, o2, immediately in front of the dies o and o', over which the strand-wire passes, so as to hold it up and not let it drop when jaw c opens. The head c is stopped in its forward movement by the stop c5, which is intended to i arrest the further movement forward bylits engaging with spring el. (Shown in Fig. l.)

Collar #has an outWardlyeXtending arm, b1, which pivots, by means of the standard b, to the frame A, so it cannot rotate with The arm b is hinged between the meeting ends of the expansible rim B3 by means of the ears b b3, Fig. 6, and its lower end is saddled over the collar Z1, so it Will stand in steps on its sides. lCollar b5 has a lever attached to it, b, so it can be rotated partially on said hub bl. Collars b'L and b5 are provided on their meeting faces with radial vertical offsets, as shown in Fig. 2, so that when collar b5 is partially rotated, it will press collar b" over against collar'b, the effect of which is to press upwardly on arm Z1', and thus expand the rim B3, so that it will have frictional contact with the inner side of the rim of pulley B2, and by such contact be driven or rotated by pulley B2, and with it the main shaft S, that drives the machine.

In order to operate the barbing part of this machine, it is absolutely necessary that a spooling device should be used in connection with it to take up the finishedv barbed wire and draw the strand-wires in and through the machine. For that reason a spooling device is shown and described, but any other suitable spooling apparatus may be used aswell as the one shown.
