BARBED-WIRE MACHINE.

SPEGlFICATION forming part of Letters Patent No. 705,394,'dated July 22, 1902.

Application filed March 22, 19oz. Serial No. 99,518. (No model.)

To all whom it may concern:

Be it known that I, WILBER EMEBY, a citizen of the United States, residing at Ashland, in the countyof Boyd and State of Kentucky, have invented certain new and useful Improvements in Barbed- Wire Machines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to barbed-wire-making machinery, and more particularly to machines of that type in-which the barbs are coiled and cut from the successively presented extremities of continuous harbingwires, an example of which is shown and described in United States Letters Patent No. 689,712, granted to me on December 24, 1901. My present invention constitutes an improvement upon the machine disclosed in said patent.

The principal objects of the invention are to provide improved coilingdevices for applying the barbs to the strand-wires, to provide means for holding the barbing-wire in rigid position during the barb-forming operation, so as to prevent its being pulled inward or otherwise displaced by the coiling devices, to render the machine adaptable for forming either two-point or four-point barbs, to simplify the construction and reduce the number of parts, and to increase the efficiency and durability of the mechanism.

The invention will be hereinafter first fully described with reference to the accompanying drawings, which form a part of this specification, and then more particularly pointed out in the following claims.

In said drawings, in which corresponding parts in the several views are designated by like letters of reference, Figure 1 represents in side elevation a barbed-wire-making machine of the type illustrated in my aforesaid patent, having my improvements embodied therein. Fig. 2 is a top plan view thereof. Fig. 3 is a horizontal sectionalview of the barb coiling and shearing mechanism. Fig. 4 is a similar view, enlarged, of a portion of said coiling and shearing mechanism, showing the strand-wires and barbing-wires in proper position for the barbing operation. Fig. 5 represents a vertical section on line V V of Fig. 2 looking in the direction of the arrow. Fig. 6 is a side elevation of the barbing-wire-feed mechanism. Fig. 7 is a detail end view of the coiling-head and cooperating cam-wheel. Fig. 8 is a detail view in front end elevation, showing the gearing and connections for operating the coiling and barbing-wire-feed mechanism; and Fig. 9 is a fragmentary View, in vertical section, of the coiling mechanism.

Referring to the drawings by specific letters of reference, A designates .the bed of the machine, which is of suitable construction and mounted on supporting-standards.

lhe letters B B denote standards located at the rear of the machine or in other suitable relation thereto, and O a hollow shaft or sleeve rotatably mounted in bearings on said standards and having thereon friction-pulleys GT and 0 one of which is loose and the other fast for the application of power to drive the machine.

. As set forth in the specification of my aforesaid patent, the hollow shaft or sleeve 0 carries a spooler and twister D in the form of a yoke or fork, having one arm provided with an idler D, over which the finished barbed wire paid out by the machine is passed and which 'in revolving twists the barbed wire and winds it around an axially-disposed reel E., The said reel is carried by a shaft journaledwithin the sleeve G and formed with a right and left screw portion which is engaged bya fork secured rigidly within the sleeve, as shown in Fig. 1, so as to reciprocate the reel, and thereby distribute the wire uniformly thereon. For the purpose of winding the wire with proper tension and compensat ing for the increasing diameter of the bale on the reel the reel shaft is also rotated at a variable speed, the difference in speeds of rotation between the driving shaft or sleeve and the reel-shaft causing reciprocation of the latter. In the construction herein illustrated the sleeve 0 drives, through suitable sprocket-and-chain conneetions, countershaft F, journaled in bearings at the side of one of the standards B and carrying a flanged pulley connected by a belt with a similar pulley secured by a spline or feather on the reel-shaft, the hub of the latter pulley being preferably journaled within the end of the sleeve to prevent longitudinal movement. The sprocket-wheels on the sleeve 0 and counter-shaft F are in a difierent ratio from that of the pulleys on the said countershaft and reel-shaft, whereby the reel and spooler are driven at different speeds, and the difierence between said ratios is preferably made slightly greater than necessary, whereby the reel-shaft is continuously retarded or driven at less than the required speed, so that the wire being wound upon the reel is continuously kept taut and by reason of its pull turns the reel independently of the driving connections, causing the belt to slip on the smaller pulley. By these means the finished barbed wire is wound with steady motion and uniform tension. However, the reeling and twisting mechanism described constitutes the subject-matter of a separate application filed by me simultaneously herewith, Serial No. 99,517, and therefore further explanation of the same herein is deemed unnecessary.

The letter G denotes a longitudinally-disposed shaft journaled in suitable bearings, said shaft being driven from the shaft 0 by means of a chain G, passing over suitable sprockets on both of said shafts and driving in turn, through similar sprockets and connecting-chain G the main driving-shaft H of the barbing-machine. The said shaft H is journaled in suitable bearings at opposite ends of the machine-bed, and power is transmitted therefrom to the barbing, shearing, and wire feeding and pull-out mechanisms.

My improved barbing mechanism is adapted for the production of either two-point or four-point barbs, and the construction thereof is exceedingly simple and efficient, as will appear from the following description. The shaft H has thereon two gears I and J of different diameters, which mesh with a pair of gears I and J, fixed, respectively, upon an inner sleeve or hollow shaft K and an outer sleeve or hollow shaft L, which are thus rotated at difierent speeds. The outer sleeve or shaft is journaled in a suitable box or bearing mounted on the machine-bed, preferably above the driving-shaft H. A coiling-head K is formed at or secured to the rear end of the inner sleeve K, the forward annular face of which head confronts and preferably contacts with a cam-wheel L, formed at or secured to the rear end of the outer sleeve L. (See Figs. 3, 4, 7, and 9.) Astationary sleeve M is preferably fitted within the inner rotating sleeve and incloses an axial rod N, which latter extends also through the centrallybored coiling-head and is longitudinally slotted at opposite sides or at top and bottom to form guides for the two strand-wires, which are intermittently drawn through the machine by mechanism hereinafter described. The sleeve M, which prevents displacement of the strand-wires in the slotted guide-rod by the inner rotating sleeve K, is rigidly secured to the rod N by a cotter-pin n or other suitable means, and the said sleeve and red are held from rotating with the other members of the barb-coiling mechanism by means of a collar m, rigidly secured on the outer end of the sleeve or on the rod, if preferred, and connected by an arm m or other suitable means to the machine-frame, as shown in Figs. 3 and 8. The coiling-head K is slotted, preferably at opposite sides of the axial guide-rod N, to receive oscillatory coiling-fingers 7c, consisting of levers or plates pivoted on removable pins within the head and having their points normally projecting beyond the face of the coiling-head for engagement with the barbing-wires and having outwardly-extending bases or tail portions, which revolve in contact with the face of the adjacent camwheel L. The said cam-wheel during certain intervals thus maintains the points of the fingers pressed inwardly or toward the center of the coiler, causing them to engage and wrap around the strand-wires the extremities of the barbing-wires, which latter are fed from opposite sides of the machine and directed between the strand-wires, as shown in Fig. 4; but at intervening periods the said cam-wheel by reason of its formation permits the coiling fingers or levers to swing outwardly by centrifugal force and also by the resistance of the wire being bent, thus separating the points of the fingers and releasing the finished barb. The relative rotations of the coilinghead and cam-wheel are so timed that this outward movement of the coiling-fingers occurs immediately after the completion of the barb, which is then severed from the barbingwires by the shearing mechanism and drawn rearwardly with the succeeding feed of the strand-wires.

The coiling mechanism is above described with reference to the production of four-point barbed wire. When it is desired to manufacture wire with two-point barbs, one of the coiling-fingers may be removed on withdrawing its removable pivot-pin, and a single barbing-wire may be fed from one side of the machine. In this case the barbs may be coiled around both strands or a single strand may be threaded through the coiling mechanism to receive the barbs and the other strand subsequently guided to and twisted with the barbed strand.

The shearing mechanism illustrated is similar to that shown and described in my former patent, with the duplications and improvements necessary for severing the two barbing-wires. (See Figs. 4 and 5.) Said mechanism consists of fixed knives P, arranged above and oblique to the barbingwires at the inner curved terminals of the guides 0 there for,and cooperating vertically-slidable knives P, bolted or otherwise secured to a slide P, mounted in suitable guideways and having its lower edge resting upon a cam Q on the driving-shaft H, whereby at the proper periods the movable knives are forced upwardly and caused to sever the previously-coiled extremities from the barbing-wires, cutting the latter obliquely to produce barbs properly pointed.

The barbing-wires are'fed intermittently to supply the necessary lengths for forming the barbs by the following mechanism. At each side of the coiling mechanism are arranged one above anothera pair of oppositelyrotating feed-rollers R, between which the barbingwire is gripped. The lower one of said rollers is fixed upon a longitudinally disposed shaft R journ aled in a suitable box or bearing mounted in/the machine-bed, and the upper one of which is fixed upon a similar shaft R, journaled in a box or bearing resting upon and hinged, as at B to the box containing the lower shaft, said shafts being suitably geared together, as shown in Fig. 6, and driven from the driving-shaft H by a chain R passing around suitable sprockets on said driving-shaft and one of the feedroller shafts, as shown in Fig. 8. A strap S passes over the upper roller-shaft boxing,the lower flat ends or bases of which are apertured and fitted over rods S,upstanding from the lower shaft-boxing or other support, and by means of coiled compression-springs S encircling said rods between their upper enlarged extremities and the bases of the strap, the upper feed-roller is pressed firmly down against the wire upon the lower feed-roller. One of said rollers, preferably the upper one, is provided with a peripheral shoulder 'r, by means of which the upper roller is raised at intervals out of contact with the barbingwire against force of the springs S thus imparting anintermittent feed to said wire while permitting continuous rotation of the feed-rollers.

For the purpose of holding each barbingwire firmlyin place during the barbing operation, so as to prevent its being pulled inward by the coiling-fingers or pushed outward by 1 resistance to the operation, the following devices are herein employed, which, however, i may be variously modified. The barbing,

wire is drawn or fed undera stationary plate or lug T, which in the present construction is formed at the upper extremity of an arm or rod T, rigidly attached to the machineframe. A movable plate T hereinin the form of a lever pivoted on the lower shaftboxing, passes over one of the bases of the strap S under the spring S and extends under the barbing-wire beneath the stationary plate T. When the upper roller-shaft boxing is raised by action of the shoulders r of 3 the upper feed-roller upon the lower feed-' roller, the movable plate or lever T is likewise raised and caused to clamp the wire firmly against the plate T, thus preventing the wire from being moved in or out during the coiling operation.

delivered continuously from the machine to permit uniform winding upon the reel, the pull-out mechanism herein illustrated being substantially similar to that shown and described in my former patent. A countershaftU,journaled in bearings suitably mounted at the rear of the machine, is driven by the main shaft H through suitable bevel-gearing and drives in turn a second shaft V through gears at the outer ends of said shafts and interposed idle gears, as shown more clearly in Fig. 2. The shaft V has fixed on its inner end a gear V, which meshes with and drives'a combined gear and drag wheel W, around which the barbed strand-wires are passed. The wheel'W is supported by an arm or lever X, which is mounted on the shaft V as an axis and oscillated by a camY on the shaft U, contacting with a roller at the rear side of said lever, a spring a; or other suitable means being employed to actuate the lever toward the machine-bed. The dragwheel is thus carried alternately outward and inward or rearward and forward, and this vibratory movement thereof around the gearwheel V causes a variable rotation of said drag-wheel faster when moving rearward and slower when returning,- so that by proper ratios of gearing the wire may be drawn intermittently through the coiling-head while moving continuously over the drag-wheel. The amount of wire drawn out by the dragwheel at each rearward travel or reciprocation compensates for the intermediate stops in the barbing-machine and is taken up by the reel during the forward or inward travel of the drag-wheel, and hence it is apparent that while the wire moves intermittently through the coiler it is wound continuously upon the reel.

The letter Z denotes an idler around which the barbed strands are passed from the dragwheel and thence to the spooler and twister D, said idler being preferably yieldingly supported with reference to pull on the wire to permit the wire to be drawn uniformly to the spooler and twister. Thewire is prevented from turning between the drag-wheel and idler Z, but is properly twisted between the idler Z and idler D by reason of the revolution of the latter around the reel in winding the wire thereon. V

The operation of the machine may be briefly summarized as follows: Power being applied to the shaft 0 at pulley O, motion is transmittedto the various operative mechanisms through the connections above described. The strand-wires are threaded through thecoiling-head K, being guided in the axial longitudinally-slotted rod N, and are drawn intermittently through the machine by the drag-wheel W andcooperating parts, while ing-plates or jaws T and T grip and hold the barbing-wires, and the rotating cam-wheel L, by engagement with the bases or tail portions of the coiling-fingers 7c in the coilinghead K, which rotates at a different speed from that of said cam-wheel, causes the points of said fingers to move inwardly and engage the pointed extremities of the barbing-wires and coil them around the strand-wires, thus forming the barb, whereupon, the bases of the coiling-fingers being permitted to recede against the depressed portions of the camwheel, the points of said coiling-fingers are thrown outwardly by centrifugal force and also by resistance of the wire being bent, while the cam Q operates the slidable knives P upwardly against the fixed knives, and thus severs the barbs from the barbing-wires. The strand-wires are then again drawn rearward, carrying the finished barb away from the coiling mechanism, while simultaneously the feed-rollers R feed in the barbing-wires for the succeeding operation. As before described, the strand-wires while being drawn intermittently through the machine move continuously over the drag-wheel W, carried by the oscillating lever X, and are paid out uniformly to the spooler and twister D, which twists the barbed strands on their way from the idler Z and winds the finished wire about the reciprocating reel E.
