SPECIFICATION forming part of Letters Patent No. 330,686, dated November 17, 1885.

Application filed July 27, 1885. Serial No. 172,801. (No model.)

To all whom it may concerwy Be it known that I, WILLIAM EDENBORN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Barb -Wire Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure 1 is a top view of my improved machine. Fig. 2 is a rear elevation. Fig. 3 is a vertical transverse section taken on line 3 3, Fig. 1, looking toward the front of the machine, the knife being omitted. Fig. 4. is a front elevation. Fig. 5 is a side elevation. Fig. 6 is a side elevation, part in vertical section. Figs. 7 and 8 are transverse vertical sections taken on line 7 8, Fig. 1, Fig. 7 showing the dies in their open position, and Fig. 8 showing them closed. Fig. 9 is a vertical transverse section taken on line 99, Fig. 1, looking toward the rear of the machine. Fig. 10 is an enlarged detail view of the horizontal dies in openposition. Fig. 11 is a similar view showing the dies in their closed position.

ribbed anvil shown in Fig. 22. Fig. 24 is a transverse section of the main wire, showing the barb in its completed form. Fig. 25 is a perspective view showing part of the main wire and a completed barb formed thereon.

My invention relates to a barb wire ma chine that is automatic in its movements, and in which both the main and barb wires are fed intermittingly; and my invention consists in features of novelty herein fully described, and pointed out in the claims.

Referring to the drawings, Arepresents the bed-plate of the machine, to which is secured the main shaft B by journal-boxes B, and a counter-shaft, B", by journal-boxes B The shafts are connected by bevel gear-wheels B. (See Fig. 1.)

The main shaft is provided with a drivingpulley, B and a small pulley, B, that is connected by belt B to a pulley, B on a shaft, 13*, journaled in boxes 13 secured to a standard, B. On this shaft is the ordinary winding-spool, B", (see Fig. 2,) the spool beingturned through means of the described connection with the main shaft, and reciprocating back and forth in the usual manner as the wire is wound upon it. The belt 13 has a tightener consisting of a pulley, U, on a rockshaft, U, having a crank, U and a ratchetwheel, U engaged by a pawl, V, pivoted to the frame of the machine. (See Fig. 2.)

Secured to the main shaft at the opposite end from the driving-pulley is a disk or crank, 0, provided with a wrist-pin, 0, connected by a pitman, 0 to a similar pin, 0, projecting from one end of an arm, 0 loose on the shaft 0*, journaled in boxes 0 secured to the bedplate of the machine. shaft 0 is a notched disk, 0 engaged by a pawl, 0 pivoted to the upper end of the arm 0 and held against the disk by a spring, 0

As the main shaft revolves .it causes the arm to move from the position shown by full lines, Fig. 5, to that shown by dotted lines, same figure, causing the shaft 0* to be reciprocated by means of the described connection, and as the arm is being moved back the shaft is held from turning back with it by means of a pawl, 0 pivoted to the bed-plate of the machine, and having an arm, 0, that extends beneath the main shaft of the machine, where Rigidly secured to the v it is struck by a cam, B on the main shaft, to

force the pawl out of contact with the notched. disk 0", rigidly secured to the shaft 0. This pawl is moved out of contact with its disk just as the parts are in position to reciprocate the shaft 0 and thus does not interfere with the movement of the shaft until a proper time has arrived. The shaft (J effects the intermittent feed of the main wire D, which passes between a roller, D, on this shaft and a similar roller, D on a short shaft, D journaled in boxes D that are hollow and fit over the upper ends of posts D", supported bythe bed-plate of the machine. Surrounding the posts beneath the boxes are springs D that act to support or hold the upper roller from bearing with its full weight upon the lower one, and this upper roller, when desired to increasethe friction of the rollers upon the main wire, is forced down by means of a cam, D, having a handle, D pivoted to a pin, D", projecting from a cross-head, D supported by the posts. (See Fig. 1.) The cam bears upon a leaf-spring, D resting upon projections D of the boxes D (See Fig. 4.) The shafts 0* and D are connected by cog-wheels D, so that a positive movement is given to the rollers as the shaft 0 is turned, as .described, and the main wire is thus fed forward intern'littingly. Before reaching the rollers the main wire passes through an eye, E, of a guidestandard, I, secured to the bed-plate. From the rollers the main wire passes between horizontal dies F and F. One of the dies has a concave face and the other a convex face, as shown best in Figs. 10 and 11. The die F is stationary, and is held in a standard,

F, projecting outward from the bed-plate, by

set-screw F, and the die F is held by a setscrew, F, in the upper end of a bell-crank lever, F pivoted at F to a projection, F formed upon the bed-plate. (See Figs. 7 and 8.) The lower end of this bell-crank lever is connected by means of a link, F to a lever, F", pivoted at F to projections F, secured tothe bed-plate. The outer end of this latter lever extends over the counter-shaft'B and is moved vertically by cam B on this shaft, and as it is raised the dieF isforced toward the stationary die F from the positionshown in Fig. 10 to that shown in Fig. 11, causing a crimp, D, (see Fig. 12,) to be made in the main wire. From the dies F F the main wire passes between vertical dies G G, having faces similar to. those F F. (See Figs. 13 and 14c.) The die G is stationary, being formed upon and supported by the bed-plate of the machine, and the die G is movable, being held in the inner end of the lever F, andbeingmoved toward the stationary die by the cam B ,which: moves the lever, asspeci'fied. Time both the horizontal and the vertical'movabledies are operated by the same cam. Thetwo sets of dies are notched, and are one inch and a half (more or less) apart, andforni separate kinks D in the main wire, the barbs being formed upon the main wires of these kinks, as

shown in Fig. 25, and are thus held from slipping on the main wire; and,moreover,the kinks allow for expansion in the main wire to prevent its breakage in extremely cold weather. The die G may be adjusted by a set-screw,G. From the vertical dies the main wire passes to and through ahollow spindle, H,journaled in boxes H, secured to the bed-plate, and provided with an elongated pinion, H", formed rigidly thereon and engaged by cog-wheel H on a shaft, H, journaled in standards H se: cured to the bed-plate. The cog-wheel is rigidly secured to the shaft, and has a notched disk, H engaged by a pawl, H at one end of an arm, H, supported loosely on a shaft, and connected by its other end to a crank, O, on the counter-shaft 13*, by meansof a pitman or -rod, O. Thepawl is held against the notched disk by spring H and itwill be seen that as'the counter-shaft revolves it-will,-

through means of the described connection,

cause the shaft H to be turned intermittingly, and likewise causes the intermittent movement of the spindle H through means of its connection with the shaft H 1 When the shaft is turned, it is held from retrograde movement by a pawl, H pivoted at H to the bedplate and held against the notched disk by spring H (See Fig. 3.) The arm is held against the notched disk by a spring, H surrounding the shaft H. On theend of the hollow spindle'is afinger, E, that catches the free end of the barb-wire, (see Fig. 19,) and twists it round the main wire, (seeFig. 20,) and as it twists'the barb it is receded by means of a rock -lever, J, pivoted at J to the bottom of the bed-plate. (See Fig. 6.) Inserted in the upper end of the lever, which is made hollow,

is' a pin,J that fits in a circumferentialgroove inthe hub of the elongated pinion H".

The pin is held into engagement with the groove by a spiral spring, J dropped into the 110 horizontal end of this bell-crank lever projects Y outward and beneath a cam, J, on the main hollow upper end of the lever. The lower sha'ft B, (see Fig. 1,) and it will be understoodthat=as this end of the crank is depressed bythe cam the pinion, and consequently the hollow spindle to which the pinion is secured,- will be moved endwise, and the parts are so adjusted that-this movement takes place while the-barb is being formed, for the purpose of removing the finger from the barb when the barb is completed, and as thecani leaves the lever the latter is caused to resume its natural positionby aspring, J and as it does so the machine.

over the counter-shaft B and is operated by cam K (see Fig. 9) to depress the hammer and cause the barbs to be pressed from the form shown in Fig. 21 to that shown in Figs. 24 and 25. The parts are so arranged and adjusted that the hammer is operated each time a barb passes between it and the anvil, and

the barbs are thus pressed so that their points project at right angles to the main wire, and they are all of uniform shape in this respect. The anvil has two small ribs, K across its face (see Figs. 22 and 23) to receive the part K of the barb while the pressing is being done. The outer end of the lever is of sufficient weight to cause the hammer to rise after the cam K*, has passed; but to insure the upward movement of this hammer I prefer to also employ a spring, K that connects the outer end of thelever to the bed-plate. From the anvil and hammer the main wire passes to and around asprocket-wheel, L, journaled to the outer end of an arm, L, extending from the bed-plate of the machine, and from this wheel the wire passes to the spool B". The barb-wire passes to the machine through an eye, M, in a bracket, M, secured to the bedplate of the machine. This bracket gives support to a sliding block, M (see Figs. land 9,) provided with a perforation for the passage of the wire,and also provided witha pawl or dog, M forced against thewire by means of the spring M The block is reciprocated by means of a shaft, M journaled in a box, M secured to the bed-plate, to which it is connected by a crank, M and pin M". The outer end of the shaft is provided with another crank, M", similar to that 1W, and to this latter crank is connected one end of the pitman M the other end of which is made fast to a crank or disk, M, on the countershaft 13*. The sliding block thus receives its movement through means of the countershaft and the described connection, and as it is moved inward the dog M takes hold of or grips the barb-wire and feeds it forward the distance of one barb. As the block is moved in the other direction the dog slips over the wire so as not to carry it backward, and this retrograde movement of the block takes place at the time the barb is being formed upon the main wire, as described. From the sliding block the barb'wire passes through a guide, N, heldin a bracket, N, (see Fig. 9,) supported by thcbed-plate of the machine. The guide causes the barb-wire to be fed across the main wire, as shown in Fig. 16, in position for its free end to be caught by the finger and twisted around the main wire, as explained.

WVhen the barb has been formed upon the main wire, it is cut off by means of a stationary knife, 0, and a movable knife, 0. The

knife 0 is secured to the bracket N by means of a plate, 0 and it may be adjusted endwise when required to compensate for wear by means of a set-screw,O (See Fig.1.) The movable knife O is secured to a block, 0*, by means of a plate, 0 and it may be adjusted endwise to compensate for wear by means of a setscrew, 0". The block is preferably triangular in shape, and is held between ears N of the bracket N by means of pins 0 and 9.) The outer end, 0 of the block is 1.0- cated over one end of a lever, P, pivoted to the bed-plate, and the other end of which eX- tends beneath a cam, P, on the main shaft of the machine. The block is thus tilted vertically as the main shaft is turned, causing the knife to be moved forward from the position shown in Fig. 19 to that shown in Fig. 20, against the end of the stationary knife, to cut off the barbs, and when the cam leaves the lever the parts resume their'natural position, giving room for thebarb-wire to be fed again between the knives or cutters.
