SIDNEY M. STEVE NS, OF DE KALB, ILLINOIS.

BARB-WIRE MACHINE.

SPECIFICATION forming part of Letters Patent No. 263,073, dated August 22, 1882.

' Application filed May 29,1882. (No model.)

To all whom it may concern Be it known that I, SIDNEY M. STEVENS, of De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Barb Wire Machines, of which the following is a specification.

This invention relates to improvements upon the machine patented to me in Letters Patent No. 243,170, dated June 21, 1881. By these improvements 1 design giving the barb-wires a greater amount of wrap around the fence-wires than was con templated by the construction disclosed in said patent. I employ in the present invention a rotating barb-applyin g wheel similar to that in my former machine; but instead of using the same barb-applying devices I mount a number of coiling-cylinders upon the wheel, such coiling-cylinders being longitudinally. slot-ted to permit the entrance and withdrawal of the fence-wire, and being intermittently rotated by stationary cams, with which they engage during a portion of the revolution of the wheel. This and other features of my invention will be particularly described hereinafter.

The accompanying drawings show at Figure 1. a plan, at Fig. 2 a side elevation, and at Fig. 3 a front elevation, of my improved "machine. Fig. 4 embraces aside view of the cam for actuating the coiling-cylinders, a central section of the barbing-wheel and said cam, and

a side view ofthe wheel. Fig. 5 is an enlarged longitudinal section of one of the coiling-cylinders with its supports. Fig. 6 is across-section of the same upon the line 00 m of Fig. 5. Fig. 7 is a like section upon the lineyy ofFig. 5. Figs. 8, 9, 10, 11, and 12 are enlarged end views of the coiling devices, showing positions occupied at different stages of the barb-applying operation. 7 1

Power is applied to my machine by a pulley, A, upon the, arbor A of a twister, A placed at right angles to the line of feed of the machine. The power is transmitted from the twister to the barbing-wheel by the gears B, B, B B B and B the first being upon the arbor A, gears B and 13 having a common shaft, B gears 13* and B having also a common shaft, B and gear B being upon the same shaft, B", with the barbing-wheel. This barbing-wheel I prefer to make .in two parts, 0 G,

relatively adjustable, as in my former machine,

and for the same reasons. One part only may be used, however, and but one of .the fencestrands be barbed. The fence-strands pass to the wheel from the rollers H below and immediately enter the longitudinal slots in the coiling-cylinders C, of which there is a series, mounted upon the periphery of each of the parts 0 G, the slotted side of the cylinders being outermost at the time they pass the pointof entrance of the wire. Said slots extend to the center of the cylinders, so the wire will lie in the axial line thereof. Each cylinder is supported upon the forward end of a stationary shaft or supporting device, 0 also slotted from its outermost surface to its axial line to permit the wire to lie centrally therein, and it is secured to the wheel through a standard, 0 cast on the shaft, and a plate, 0 bolted or screwed to the wheel. The depending rib O has an outward projection, 0 which engages with a shoulder, 0, upon the cylinder, and so retains the latter upon the shaft.

The barb-wires are fed to the machine by pairs of friction-rollers 1), which are operated from shafts D by the nest of gears 61 d 01 Said shafts D receive power from the shaft 13,

as follows: Bevel-gear D upon the shaft 13 meshes with another gear, D upon the shaft D Said shaft D carries two gears, D and D one of which meshes with the gear D upon one of the shafts D, and the other of which meshes with an intermediate gear, D and that with the gear D upon the other shaft D. Between the rollers and the barbing-wheel the barb-wire passes through guide-tubes D upon the frame of the machine, whereby they are deflected sufficiently to give the proper bevel to the cut of the knives E and E. Of the knives, the two lettered E are stationary and held in the frame of the machine, and those lettered E are held in the periphery of the barbing-wheel. Of 'coursethere is one of the latter for each coiling-cylinder. Y

Fig. 8 shows the position of one of. the coilin g-cylinders when ready for the entrance thereinto of the strand-wire-that is, with the slot therein coinciding with that in its shaft-and both open outwardly from the wheel. In Fig;

9 the barb-Wire has been fed in between the strand and the wheel, so that its inner end rests upon a spring-lever, E which is pivoted at its forward end to the standard 0 of the next preceding cylinder, and supported at its other end by a spring, 0. The barb first rests upon the forward part of the lever, and slides back thereon until it lodges in the recess therein, as shown in Fig. 5. By the time it has reached this position it is ready for the coiling operation, and I provide the recess in order that it may be retained measurably at the start of that operation. A set-screw, c, prevents too much depression of the lever. In Fig. 10 the coiling projection c has carried the outer end of the barb a quarter-turn. In Fig. 11 the coiling is complete, and in Fig. 12 the coiling-cylinder has been retracted slightly, so the slots in cylinder and shaft again coincide and the wire has been partially lifted from out of the same.

It will be noticed that during the coiling operation the strand-wire is wholly inclosed by the cylinder, so as to be able to withstand the lateral pressure or strain caused by the coiling, except during the instant the slot in the cylinder is crossing in its rotation the slot in the shaft; but this crossing does not occur until after the barb has been sufficiently wound to have a clamp of its own upon the strand, and, besides, the strand is then bent in conformity to the line of the wheel, so that no tendency to escape exists at such times. The inner end of the barb rests upon the lever E until the barb is almost coiled and so long as its support is required.

The rotation of the cylinders for the performance of the coiling operation is insured by the teeth 0 thereon entering the grooves upon the side of a cam-ring, F, encircling the wheel and secured firmly to the frame-work of the machine. This ring has such a number of spiral grooves f extending across its side surfaces as may be necessary to rotate the cylinders the required amount, each of said grooves moving the cylinder the proper distance to insure the entrance of the next tooth into the next groove. Thus in the drawings there are shown eleven of .such grooves, so that cylinders provided each with five teeth will be rotated twoand onefifth revolutions in passing this part-ofthe ring. In order to bring the cylinders back to the open position and permit the withdrawal of to 0011 it.

the wire, the last of these grooves-to wit, the one at thetop of the ringmarked f-r'everses their direction one-fifth of a turn, leaving the net rotation made by the cylinder an even two turns, while the barb may have received two and a fifth turns, or a less amount, depending upon thepointatwhich thecylindercommenced After thus reversing the movement of the cylinders the same tooth which passes through the groove f is continued into the concentric groove f which extends the remainder of the distance around the ring and opens into the first of the spiral groovesf, thus the wheel.

keeping the cylinders with the open side outermost until the strand-wire has again passed within their embrace. All the cylinders being alike, in these particulars they are operated alike by the cam-grooves inthe ring, and the operation is repeated with each revolution of By this construction, also, thecylinders are at all times controlled by the ring, so that a perfect timing of their movements is obtained, and they can never fail of being in the right position at the receiving and discharging moments. Each side of the wheel applies the barbs to a strand of the fence, and,

after being barbed, the strands are brought together by the horizontal rollers G G and the feed-wheel G, either with the barbs in such close fellowship that they will form in the twisted cable what is commonly called a fourpointed barb, or they may alternate-that is, those upon one strand may be located midway between those upon the other strand, these different results being brought about by the relative adjustment of the two parts of the wheel. Said feed-wheel is positively operated at a fixed speed by the bevel-gears G and G the former upon the shaft D and the latter upon the shaft of the feed-wheel. feed-wheel the wires pass at right angles to the twister, as already explained.

Of the barb feed-rolls one of each pair receives motion from the nest of gears 11 01 d while the mate rolls are operated from the ones so actuated by pinions d and d. The return movement given to the coiling-cylinders by the grooves f is of special importance, because the coil given to the barb should be such a one as will leave its points looking in the proper directions, and such conformation can only be imparted by revolving the coiler something more or something less than a complete revolution or number ofrevolutions. The coiling projection upon the ends of the cylinders is adjustable thereon, being held by a screw passed through a circular slot, as clearly shown in Figs. 8, 9, 10, l1, and 12. It also has a lip, which partially incloses the wire and prevents its escape from the projection during the coilmg.

The depending ribs 0 set down into the annular groove m of the wheel, whereby I am enabled easily and accurately to position them on the wheel.

So much of the coiling-cylinder as comes in contact with the fence-wire is made short, as shown, so as to avoid as far as possible any tendency to twist the said wire with it in its rotation around the same. The non-rotating support, on the contrary, is of such length as to afford the wire a long bearing.
