v To all whom itmmy' concern:

Be it known thatl, GUSTAV Gnrnsclrn, of the cityof St. Louis, in the State of Missouri, have inventeda certain new and useful Improvemcnt in Barb-Wire Machines, of which the following is. a full, (3188.1',-2t11d exact de-' scription, reference being had to the accompanying drawings, forming part of this specification, and in which Figure 1 is a vertical section taken on line 1 1, Fig. 2. Fig. 2 is a top view. Fig. is a horizontal-section taken on line 3 3, Fig.5.

Figs. 7 and S are detail side views, parts in section, of the device for moving the barbwire. Fig; 9 is a detail section of the grooved feed roller or wheel of the main wires. Fig. 10 is a vertical transverse section taken on line 10 10, Fig. 11. Fig. 11 is a vertical longitudinalsection taken on line 11 11, Fig. 2. Fig. 12 is an enlarged view of one of 'thecamsfor operating the formers. 13 is a section on line 13 13, Fig. 11. Fig. 14; isa section on line 14 14, Fig. 11. Fig. 15 is' an end View of one of the formers-showing the end of one of the fingers. Figs. 16, 17,18, 19,20, 21, and22 are diagrams illustrating the manner of forming ghelharb. Fig. 23 is a view of the complete ar This invention relates to a barb-wire machine which applies the barbs during the movement of the main wires; and this invention consists in features of novelty hereinafter fully described, and pointed out in the claims. Referring to the drawings, A represents the bed-plate of the machine, which would'rest upon proper supports.

A represents a drivingpullcy on a shaft, A", journaled in a box, A, secured to the bedplate A. The shaft is hollow, and through it pass the main wires 3 3, after the barbs have.

been applied. The wires pass from the hollow shaft to a flier, (not shown,) which twists them.

7 7 represent the wires from which the barbs are cut.

On the inner end of the shaft or spindle A is a cog-wheel, A, meshing intoa similar ards A.

wheel, A on a shaft, A, journalcd in boxes A secured to the under side of the bed-plate. On the shaft A is also a. miter-wheel, A, meshing into'a similar wheel, A", on a transverse shaft, A journaled in boxes A, secured to the bed-plate.

Onthe outer end of the shaft A is a pinion, A", which meshes into a large cog wheel, A,

on a shaft, A, journaled in boxes A, secured to standards A, supported onthe bed-plate.

.On the shaft A are heads 13, carrying reciproeating barb-formers B, (see Fig. 11,) operated by cams B, rigidly secured to the stand- The cams have inclines B B (see Fig. 12,) for pushing the barb-formers for ward to produce the .d-iiferent parts or bends of the barbs, and have inclines B, to allow the formers to be drawn back by flanges 13 on the peripheries of the cams which engage pins 13 on the inner end -of the formers.

The formers preferably have friction-rollers B9, against which the cams bear. It will thus 'be seen that as the shaft A is turned by the described gearing, carrying the formers around, the formers will he forced forward at intervals, (producing the barb, as hereinafter explained,) and thenare drawn back as the.

shaft continues to rotate, to be in position to form another barb.

Each former is preferably made in two parts, the inner part telescoping the outer part, (see Fig. 13,) and adjusted by a sot-screw, B reached by removing the friction-roller, and held to its adjustment and kept from turning by a set-screw, B. \Vear of the formers can thus be compensated for, so that they can always be kept the'same length. The heads are provided with steel bushings B, through which the inner ends of the formers pass. (See Figs. 11 and .14.) In the inner ends of the formers are notches B and grooves 13, which receive the ends of the wires in forming the barb;

On the shaft A, between the heads P), is a wheel or disk, (3, consisting of a separate piece or an extension of one of the heads and of less diameter than the heads, to which are secured fingers G, which project beyond the periphery of the wheel, and are inclined,as shown in Fig. 10. There is a setof these fingers on each side of the disk, (see Fig; 16,) and they act to main wires, and to compensate for wear.

.19, 20, and 22.

remove the barbs from the holder shown in Fig. (5, (passing between the holder and knives or cutters) and carry them up between the disk (1 and' a roller, (3", secured to a shaft,

journaled in boxes U, secured to standards 0", resting on the bratplaie. The roller 0" fits between the heads-I3, and as the barbs are carried up by the fingers (1' between the disk 0 and the roller (F they are bent into the form shown in Fig. 17. The main wires 3 pass up between the roller 0" and the disk 0, as shown by arrows, Fig. 10, and the roller has grooves C, (see Figs. 9 and 10,) to receive them. They pass between the two series of fingers, as shown in Fig. 16. Before the barbs leave the roller 0" the formers come against the inclines B of the cams and are advanced tight up against the wires, and as the barbs leave the roller 0* the formers come against the inclines B" of the cams and are moved forward, bending the barb into the position shown in Fig. 18, and then the barbs pass under a narrow roller, H, (see Figs; 1, 2, 10, 11, and 19,) which issecured to a shaft, II,

journaled in boxes H", supported by the standards A. This shaft may be turned by a cogwhcel, H, thereon, engaged by a wheel on the shaft A (Not shown.) The wheel H fits between the formers and presses the barb from the position shown in Fig. 18 to that shown in Fig. 19, and as the barb leaves the roller H the formers are again advanced by the inclines 5 of the cams, and press the barbs into the position shown in Fig. 20, bending them around the main wires, as shown in Fig. 23. As this part of the barb is being formed, the central part rests in a cross-groove, 0 (see Figs. 10 and 22,) on the periphery of the wheel or disk 0, and the ends enter recesses 0. (See Figs. These recesses are necessary to permit the barbs to be bent. The formers having now completed their function, they are withdrawn by the flanges I3 on the cams B", which engage the pins 13 on the formers, as above described. The inclines B permit the backward movement of the formers.

N represents a roller on the opposite side.

of the diskC to the roller 0 which is secured to ashaft, N, journaled in boxes N fittingiri slots N (see Fig. 1) in projections N" of the standards A. The boxes can move vertically in the slots N, to allow the roller to be moved slightly from or tothe disk for different-sized vertical movement of the roller may be regulated by set-screws N". (See Fig. 1.) The rollers (F and N move the main wires forward over the disk 0. As they are bent out of astraight line in passing over the disk, they are not liable to slip. A roller, 0, may be located beneath the roller N, secured to a shaft, 0,

journaled in boxes 0*, secured to the bed-plate A.

As the main wires with the barbs pass between these rollers N O, the barbs are flattened down. After passing between the rollers NO, the main wires pass through thehol- This low shaft A and to a flier of any ordinary construction, where they are twisted together, asusual. The barb-wires 7 are moved forward alternately, and pass through bent tubes I, (see Figs. 1, 3, and 4,) securedto the standards I, through which they pass, and held to any adjustment by set-screws I". These barb-wires, before passing through the tubes I, pass between feed-rollers 1 1', (see Figs. 3 and 4,) secured, respectively, to shafts I l, j ournaled in boxes 1 fitting in vertical slots 1. of the standards I and outer standards, I". The boxes of the upper rollers, I", may move in the slots 1* to allow the passage. of wires of different sizes, and they may be held at any point by set-screws I", passing down through the tops of the standards. (See Figs. land 4.) The feed-rollers are turned to advance the wires 7 alternately by pins 13, projecting from the peripheries of the heads 13. which engage with rag or sprocket wheels 1 (see Figs. 2, 7, and 8) on the shafts F. pins are preferably screwed into the heads, as shown in Fig. 7, so as to be lengthened or shortened, and are held to their adj nstment by j am-nuts I. As the barb-wires are fed forward, they are cut off into proper lengths by movable knives or cutters Jone for each wireacting against stationary knives J secured in the standards C". (See Figs. 3 and 5.) The knives J are secured to arms J, hinged at J to the bed-plate A. (See Figs. 3, 4, 5, and 6 The cutters are secured to the free ends of the arms by set-screws J, fitting in slotsJ in the cutters and screwing into the vertical parts of the arms. (See Fig. 6.) They are adjusted from beneath by setscrews J passing through lugs J on the arms. (See Fig. 5.) The free ends of the arms are raised to operate the cutters J by means of a collar, L, on the shaft A, provided with cams L L", whiehrcspectively come in contact with friction-rollers J t, journaled to the arms. (See Figs. 1, 3, 4, and 5.) As the barbs are out off, they fall into or are held by a holder, M, secured to the-bed-plate, (see Figs. 5 and 6,) consisting of a plate forked at its upper end either by being split or by having a piece attached. The barbs are held by this holder until removed by the fingers as above described.
