82E JIFIGATIOII forming part of Letters Patent No. 291,902, dated January 15, 1884,

Application filed June 18, 1883.

(No model.)

. citizen of the United States, residing in Chicago, in the county of Cook and State of. Illinois, have invented a new and useful Improvement in Barb-Fence Machines, of which the following is a specification.

My invention relates to improvements in ma chines for applying barbs to fence-wire.

The object of the invention is to provide a machine of simple and durable construction, which will apply barbs to fence-wires with much greater rapidity and facility than machines heretofore commonly in use.

In barbed-fence machines heretofore in use the fence-wires and the barb-wire have generally, one or both, been fed intermittently through the machine, and the barb-applying device and other moving parts of the machine have been given a variety of stop motions, reciprocations, oscillations, &c., by means of cams and other devices, so that ordinarily such machines have been very liable to get out of order or repair, and have not been capable of being run at a high rate of speed. In the present invention both the barb-wire and the fence-wires are passed through or fed to the machine continuously from their appropriate reels or spools, and all the barb-applying de vices and moving parts of the machine have a simple continuous rotary motion without any stops or interruptions. It will readily be understood, therefore, that abarb-fence machine constructed in accordance with my invention may be run at very high speed and be made to apply the barbs with very great facility. I11

my invention the fence-wires are carried over a continuously-revolving wheel or drum located. between the delivery and receiving spools or reels for said wires, and the barbwire is fed continuously transversely across the face or periphery of said revolving drum and the fence wires thereon. A series of knives fixed in the periphery of said drum, at or near one edge thereof, opposing themselves to a stationary tangential knife fixed in the framework of the machine, severs the barb as the drum revolves into the length necessary to form the barbs. The knives are so set as to sever the barb-wire on a diagonal cut, and thus point'the barbs. Each barb as it is severed drops or is forced into one of a series of transverse grooves or holding devices in the pe riphery of the drum, wherein the barb is held and carried on the drum while the barb-applying devices are affixing it to the fencewires. The barb-applying devices consist of rotary tools journaled inside or outside the drum, 'and operating on the barb through suitable slots in the drum.

In the accompanying drawings which form a part of this specification, I have shown a machine embodying my invention which is particularly adapted to apply the particular form of barb shown in Fi 6 of said drawings-that is to say, a barb having a C-shaped loop at its middle portion, the twisted fence-wires being embraced between said loop and the points of the barb.

I11 said drawings, Figure 1 is an end View of the machine. Fig. 2 is a vertical longitudinal section, partly in elevation. Fig. 3 is an enlarged detail sectional view of the twisting device. Fig. 4 is an enlarged detail sectional view of the drum and barb-applying devices. Fig. 5 is a detail radial section of same; and Fig. 5 is a similar view, showing the rotary tool partially receded from the re oess between the chucks. Fig. 6 is a view of the completed barbience wire which the ma chine shown in the drawings is designed to make. Fig. 7 is a view of same before the fence-wires aretwisted together. Figs. 8, 9, 10, andll are views of the barb in the successive stages of its formation and application to the fence-wires. Fig. 12 is an enlarged detail perspective View of the steel plate or block inserted in the drum, so as to form part of its periphery, and in which the transverse grooves for carrying the barbs are cut; and Figs. 13 and 14 are respectively enlarged detail end and side views of one of the rotary tools.

As the barb is severed, as shown in Fig. 8, it falls or is caught in one of the series of transverse grooves in the periphery of the drum, being forced or guided into said groove by a pair of concave cheeks outside the drum and concentric therewith, fixed to the stationary fraine of the machine. The lower extremity of the concave cheeks, where the barb is fed across the drum, is slightly beveled or rounded off, so as to crowd the barb toward the drum, when it is caught by the back edge or wall of the transverse groove on the pcriphery of the drum, the back edge of the transverse groove being higher than the front edge, or projecting out farther on the periphery, so as to catch the barb in the groove as the drum revolves the instant the barb is severed from the wire by the knives; and at thev same time one of a series of revolving tools or formers journaled inside the hollow drum 011 fixed bearings, projecting through one of a series of slots in said drum, forces the middle portion of the barb between the stationary concave cheeks outside the drum, thus giving the barb the form shown in Fig. 9. The retary tool or former describes a circle much less in diameter than that of the drum, so that the tool after it passes the common radial line willreeede from the drum and the barb thereon as the tool and drum continue to revolve. After the tool has receded from the barb sufficiently to allow the extreme part of the bend thus formed in the barb to be bent again at right angles to the plane of said bend, the revolving tool, opposing itselfto a stationary tool projecting from between the concave cheeks, bends the barb into the form shown in Fig. 10. The rotary tool is geared, so that its surface speed is about the same as that of the drum or the barb carried thereon. The fence-wires lie on the drum on each side of the bend formed in the middle portion of the barb, which bend projects between the fence-wires, and as the drum continues to revolve the fence-wires are crowded nearer together on the surface of the drum by means of a pair of small rollers grooved to fit the wires journaled on the frame-work of the machine, thus bending the barb into the form shown in Fig. 11. As the drum continues to revolve, a pair of rotary swages or tools, one journaled inside and one outside the drum, projecting through the slot in the drum, and opposing each other, force the bent middle portion of the barb down fiat upon the fencewires, as shown in Fig. -7. The two fence wires are then twisted together by the twisting device, thus giving the barb the formshown in Fig. 6, and securely affixing the wires in the opposite shoulders or notches formed by the C-shaped loop and the endsof the barb. The twisting and spooling device is suspended in a vertical position from a ball-and-soeket joint, the lower end of the frame being loose or unconfined, so that the revolvingspool and frame may always instantly adjust itself to its center of gravity or rotation as the same changes from the changing shape and size of the growing spool of wire. The twistingframe may therefore be revolved at a very high speed without any danger or injury or causing any vibration.

In the drawings, A represents the :frame of the machine, and B is the revolving drum or wheel fixed to a shaft, B,-suitably journaled in said frame. The fence-wires a a pass from their delivery-spools parallel to each other over a grooved guide-pulley, a and thence side by side over the drum B to the wire pulley at at the month of the twisting device. The drum B is provided with a series of slots, 1), through its rim. These slots are equidistant apart, and may preferably be in the central portion of the rim. In the rim of the wheel B, near one edge thereof, are fixed rigidly a series of knives, b, for severing, in connection with the opposing stationary knife b, the barb from the barb-wire as the wheel B revolves. b represents a series of transverse grooves in the periphery of the wheel or drum B, extending centrally across the slots b. The barb-wire c, from which the barbs are cut, is fed continuously transversely across the periphery of the wheel B, immediately under the stationary knife b", by means of a pair of constantly-revolving feed-rolls or other suitable mechanism. The knives b and b have their enttingedges set to sever the barbs from the barb-wire on a diagonal cut. The rimofthe wheel B should preferably be about as wide as the severed barb-pieces are long.

D and D are a pair of parallel concave cheeks or flanges concentric with the drum B, and fixed rigidly to a bracket, D which is secured by suitable bolts to the frame of the machine. As the barb 0 is severed by the knives b b from the barb-wire c, it is forced or guided by the concave cheeks'D Dinto one of the transverse grooves b in the periphery of the drum as the drum revolves, and there retained by said concave checks until the barb is partially formed, as hereinafterexplained. The concave cheeks D D have their faces slightly inclined or beveled toward the drum at the point where the barb-wire isfed across, soas to guide the barb into the transverse groove in the drum as the barb is caught by the projecting back edge or wall, b, of the groove'b", which is somewhat higher than the front edge of said groove.

d d are a series of revolving tools fixed rigidly in the periphery of a wheel, d, fixed to a shaft, d, which is journaled on the frame of the machine, inside the peripheral line of the drum or wheel B, so that the barb formers or tools d d may project through the slot 12 in the drum B as the drum and tools revolve around their respective centers. As the barb is severed from the barb-wire, one of the revolving tools d, projecting through the slot 'b, forces the middle portion of the barb 'be-. tween theeheeks D D, thus bending it into the form shown in Fig. 9. The tools dd have longitudinal grooves in their opposite edges or faces for the barb-wire, into which grooves the bent middle portion of the barb, as shown in Fig. 9, rests, and is held. The bend in the barb (shown in Fig. 9) is completed when the revolving tool (1 reaches in its revolution the common radial line passing through the centers of the shafts d and the shaft B of the drum. After passing this point, the tool begins to recede from the recesses between the concave cheeks D D.

Fixed'in the bracket D and projecting'be tween the cheeks D and D, is a tool, (1 which IIO 29:,902 I It serves to bend the fold already formed in the barb at right angles to its plane, as the revolving tool (I and the drum continue their revolutions past this projecting tool The form given the barb by this operationis shown in Fig. 10 in perspective. The position of the barb and of the tool (I at the time or just before the second bend is formed is shown in Fig. 5". \Vhen the projecting portion of the barb, as shown in Fig. 5, strikes the stationary tool (1 the longitudinal or radial grooves in the tool cl serve to hold the barb while the projecting portion is bent down at right angles across the end of the tool (1. After the barb is carried by the revolution of the drum past the concave cheeks D D, the fence-wires f 1 a a lying on the drum will serve to retain the barb in position in its transverse groove. The bend formed in the middle portion of thebarb projects up between the fence-wires, which lie side by side on the smooth surface of the drum.

E and E are a pair of small rolls, having their peripheries grooved to fit the wires to a, located tangentially to the drum B, and journaled on a crossbar, E secured to the frame of the machine. The purpose of these rolls is to crowd the two fence-wires nearer together as the drum revolves, and thereby force the barb into the form shown in Fig. 11.

e e are guides projecting between the fencewires from the central portion of the periphcry of the drum, to keep the fence-wires apart, and to regulate the action of the rolls E and E in crowding the fence-wires together. The projecting guides 6 also serve as supports for the bent middle portion ofthe barbs, as shown in Fig. 10, to rest against, and thus prevent the barbs from slipping back as the fencewires are crowded together by the rolls E and E. For convenience of construction the projection e and the transverse grooves b can best be made, as shown in Fig. 12, in asingle steel block or dovetail piece, 1 secured in a suitable dovetail slot or mortise in the face of the drum, so that the piece 3 will be flush with the periphery of the drum or form part thereof. Part of the slot b will of course appear in this dovetail piece.

H H represent a series of revolving swages or tools secured in the periphery of a wheel, H, secured to a shaft, 11*, which is journaled in suitable'bearings on the frame of the machine, so as to project inside the drum B and h h are a series of similar revolving swages or tools fixed in a wheel, h, secured to a shaft, h, which is j ournaled outside of the drum B in suitable bearings 011 the framework of the machine. As the drum B continues its revolution, the harb, as shownin Fig. 11, is carried between a pair of these revolving tools H h, and the loop or bent middle portion of the barb is thereby swaged or pressed down fiat upon the fence-wires, as shown in Fig. 7.

F represents the drive-wheel of the machine on the shaft F. The revolving tools h h are driven from shaft F by means of gears f, meshing with gear f on shaft f and bev eled gear f 3 on said shaft, whichmeshes with beveled gear f on shaft h to which the toolwheel is secured. The revolving tools H and d are operated from the shaft h by intermeshing gears I I 1' I on the shafts h", H, d", and

1*, respectively. The drum B is operated from the shaft F by means of the worm J on said shaft meshing with the worm-wheel J on the drum-shaft B. barb-wire are revolved by means of the beveled gear {1 on the feed-roll shaft meshing with the beveled gear on the vertical shaft which is operated from the driving-shaft F by means of the intermcshing gears g and I l The checks or liangesD and I) are secured in position by bolts passing through slots in the same, so that they may be adjusted to different The feed-rolls O for the I distances apart, as may be desired. The knives I) are adj ustably secured by suitable keys or. screws in radial slots or grooves in the wheel B, and the stationary knife b is also secured adjustably by suitable keys in a slot in the bracket D". The fence-wires, with the barbs secured thereon, as shown in Fig. 7, pass from the wire-pulley a, through the hollow shaft (0, to the spool K, which is mounted in the twisting-frame M. A The twisting-frame M- is supported and suspended from a ball, N, which rests in a ball-socket, N, secured to the bracket N", which is fixed to the frame A by suitable bolts. The frame M is secured rigidly to a hollow sleeve, N which in turn is fixed rigidly to the ball N, and frame M thus secured to it is revolved by means of a pulley, N, which is fixed to the ball N by suitable screws or bolts. The lower end of the frame has no hearing, but is provided with a short shaft, m, having a friction-pulley, m, thereon, which is loosely confined in a large shell or cup, m the shell or cup being large enough to permit the lower end of the frame to vibrate or move sufficiently to bring the center of gravity or rotation of the frame and the spool by means of the bevel-gear n on the spoolshaft n meshing with the bevel-gear a on the end of the jointed shaft at, which shaft is driven from the hollow shaft (0 by the intermeshing gears a and n The hollow shaft a is held stationary, so as to drive the spool-shaft by means of a friction-pulley, aflsecured to said shaft, and a i'rictionclamp, a". The friction-clamp a" is supported by the sleeve a, or the pulley aflsecured thereto, and is prevented from rotating with said pulley by an arm or projection, which comes in contact with the standard 0. The frictionrlamp a is pressed against the friction-pulley by a screw-bolt furnished with a hand-wheel or other suitable means, so that the pulley may revolve when the tension on the wire is too, great. The

wire-pu1ley" a at the top or mouth of the twisting device is mounted on a bracket, 0, and is provided with a number of small curved arms, 0, extending out from the rim of the wheel on one side thereof, so as to form a proper support for the parallel fence-wires as they come from the machine, and not disarrange or alter the position of the barbs thereon before the same are immovably fixed by the twisting of the wires together.

The particular device for twisting the fencewires together and spooling the cable herein shown is of my invention, but is not herein claimed, and the same is hereby expressly reserved as the subjeetmatter of a separate application, as is also the particular form of barbed wire herein shown, the great advantage of which consists in its adaptability to be manufactured with very great rapidity, and by simple and continuously positively-moving machinery.
