C

The nature and object of this invention are `to form wire barbs, such as are shown in Fig. 6, on `thefence-wires c at convenient intervals by their being intertwined and coiled around the two strands c,toformfour points, as shown in said Fig. 6, for fence purposes. In order to `perform this the entire operation of feeding in the barb-wires o, coiling them on the strands, cutting them oft', and returning the parts to the starting-position is laccomplished at one revolutonof the shaft S. One revolution of the shaft S rotates the Wheel B5 half-way around, because the cam g5 will return the carriage H, so the ycams a' and p will disen gage from each other and` only rotate the wheel half -way around, leaving the opposite cam, p, to be engaged by the cam a' at its next revolution, so the cams a! and p engage with each other alternately. The wheel B5 has three times the circumference of the wheel B', and when it rotates half-way around rotates the wheel B once and one-'half time to coil the barb that many times around the strands c.

` In the drawings, Ais the main frame ofthe machine, and is supportedbysuitable legs L. 5o The frame A is rectangular in shape and bears the working parts ofthe machinery,and is provvided on its. lower side extending its entire length with the main drivingshaft S, and immediately above it with the reciprocating carriage H, which travels back and forth in the ways L5, (shown more particularly in Fig. 3.) Motion is imparted to the machine by a belt on the pulley D, on the hollow shaftof the twister-frame It, which has attached on its inner en d the pinion z, from which .the larger 6o pinion F and the shaft S, to which it is Iirmly keyed, receive motion. About central on the shaft S is the cam-wheel g3, firmly keyed to it, which' cam g5 rotates between the `frictionrollers i2 on the lower end of the arm H, which 65 arm H8 is permanentlyfixed to thereciprocating carriage H above it,\as shown in Fig. 2, so that when the cam g3 rotates it lreciprocates the carriage H. 4 The shaft S is also provided with the sleeve f, which reciprocates with the 7o carriage H by bengboxed toit by the arm P2 and boxing Z, Fig. 3, and also rotates with said shaft S onaccount of being feathered to it by the spline S3. The upper end of the sleeve f bears the pinion B5, which rotates loosely and intermittently on it, and rotates intermittently the smaller pinion B' above it, provided on its front face with a pair of projecting coilingpins, ac3, to coil the barb-wire. The extreme upper end of the shaft S is provided with the 8o i cam a', firmlykeyed to it, so as to rotate with it. When the shaft S rotates thecam g3 will move the carriage H toward the cam a until it engages with one of the projecting lugs p on the sidev of the wheel B5, and rotates it halfway around when the two cams d and p dis-v en gage by means ofthe cam g5, returning the carriage H to its starting-point. When it re-- turns again it engages with the opposite lug, p, performing a like operation, so that each time 9o the carriage H reciprocates the wheel B5 is rotated half-way around, andin turn rotates the coiling pinion- B( once and one half time around, as before stated. 'The coilingpinion B rotates on the hollow shaft c, held firmly ing 5 the boxing c3, through which the wire-strands c are guided in the two opposite grooves ofa long rod, x4, inclosed within the hollow shaftc4, (shown more particularly/jin Figs. 3 and 8,)

so -the wire-strands c will pass through it par- :coo

' grooved guide-rod :v4 perspectively and in detail. The two coiling-pins :v3 on the face ofthe coiling-pinion B are set exactly opposite each uother, and are held in place by the set-screws 5v5, which ceiling-pins are the twisters that coil the barbing-wire o around the wire-strands c, and are shown particularly in Figs. 2, 3, and i. The barbing-wireo is fed into the machine from either side off the spools a2, just at that point, so as to pass between the two strands c and between the two coiling-pins w3 through a throat under the plates T,in the position shown in Fig. 5, so they will lie between the cutting: dies d and d. When the barbingwires o are in the shape shown in Fig. 5, the carriage H moves as aforesaid until the cam a engages with one of the lugs p on the pinion B5, causing it to rotate the ceiling-pinion B', so the coiling-pins x3 willcatch the ends of the barb'- ing-wire o, and coil them around thestrands c, in the shape shown in Fig. 6. At this instant the cam a and lug p disengage, causing rotation of the coiling-pinion B to cease, when the cutting-dies d', which are rmly set in the frame R", hinged at one end by the hinge B8 in the side of the carriage H, are forced upward by means of the lug f on the sleeve f rolling against the frictionroller R in the lower end of the frame B7, causing the frame R7 to rise with the lower dies, d', so the barb-wire o will be sheared off diagonally between the upper dies, d, and the lower dies, cl, after which the barb passes on and the carriage returns to perform another like operation.

lhe upper cutting-dies, d, are held firmlyin the frame B, which is supported at either end to the carriage H, to which it is firmly bolted.

The spiral spring L8 is for the purpose of holding down .that end of the die-frame R, so

the roller R6 will roll on the sleeve f continuously. By this method the strand-wires c travel continuously through the machine in the direction indicated by the dotted lines and arrow, and the barbing partof the machine travels with it to put on the barbs. v

After the barbs are formed on the wires c as aforesaid, they need to be straigh tened up, so the points will stand at right angles, or nearly7 so, with the strand wires c. This is accomplished by the long guide-plates r on the top of the carriage H, and the stops t' attached to them. These guide-plates r are just far enough apart so the barb can draw through between them, as shown in Fig. 1. When the barb comes along its legs or prongs come against these stops i, they are arrested in their progress until they are bent at right angles with the strand-wires c, after which 'they slip over the stop i by being drawn up an incline left on the corner of the stop. (Shown particularly in Fig. These stops t' are placed on the plates i, so one is above and one below as one leg or prong of the barb is above and one below the plates r as it passes along. Fig. 9 is a per-v spective view of a plate, r, having a stop, i',

and showing the corner of the stop inclined s0 the barb can be drawn over it as aforesaid.

The mechanism for feeding the barbing-wire o into the machine -is shown particularly in Figs. 1, 4, and 10, and consists Aof the link z2 and wbellcrankla w', lever V, sleeve rod y, bolt ys, and beam E. to the top of the main frame A at z2, while the elbow of the bell-crank t w is pivoted to the t'op of the outer end of the plate E, which plate E is bolted at its inner end to the top o f the carriage H, as shown in Fig. 1, and reciprocates with it. The link z2 is attached tothe inner end of the long` arm of the bell-crank c w', so that when the carriage H reciprocates it holds that end of the bell-crank stationary, causing it to reciprocate the sleeve or ou the rod y back and forth. The barbingwire o passes off the reels a2 through a throat on the side of the sleeve x, as shown in Figs. 1, 4,and 10, between the square rod or die yf and a die at m3. When the sleeve m moves toward the machine the wire o is caught between the square die ys and the die m3 and carried forward as far as the sleeve .r moves. When the sleeve returns the wire o is relieved from pressure and remains stationary to be caught and c arried forward on the return of the sleeve :was stated, thus placing the barbing-wires oin the machine in the position shown in Fig. 5, crossing each other between the two wire-strands c at the instant the coiling-pins x3 are in position to revolve and coil them about the strands c, to form the barb as stated.

The plates T, Fig. 5, lie on the top of the die-frame R", and are provided with a throat between them and the frame, through which the barb-wires are forced by the feed, to hold them in place and conduct them in right position between the strands c. By this feed described the barb-wires o are fed into the machine from either side off the spools a2 simultaneously, as needed.

In order to hold the cutting-dies d and d in place in their respective frames the bolts we, having the wedge-shaped heads w8, are used, the wedge-shaped heads w8 wedging the dies against the frames they set in, to hold them rm, as shown particularly in Fig. 5. Thenut w1 on the end of the bolt w6 is for the purpose of drawing the wedge-head of the bolt up firmly between the dies, as stated.
