SPECIFICATION formingxpart of Letters Patent No. 241,442, dated May 10, 1881. Application filed September-'29, 1879.

To all whom it may concern:

Be it known that I, DA IELS. S'rovER, of Freeport, county of Stephenson, and State of Illinois, have invented certain new and useful 5 Improvements in IVire- Barbing Machines and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and

This invention relates to certain improvements in wire-barbing machines, and is an im- 0 provement on a machine for which Letters Patent of the United States were granted to me October 23, 1877.

The invention consists in the combination of mechanism so constructed and arranged,

5 as hereinafter described, that barbs may be wrapped upon one wire, said barbs cut by a continuous and automatic operation, and that, too, while the longitudinal or main wire or Wires is or are moving forward with a uniform speed, although the barb-wire is fed intermittently.

Fig. 9 represents an I It also consistsin the combination of a friction-roller and plates, as hereinafter described, for holdingand properly conducting the barbed wire from the point at which the barbs are wrapped upon the wire to where the two wires are intertwisted, and also in an adjustable guide for conducting the main wires in between the feed-rolls, and of an eccentric device for raising and lowering the upper feed-roll, so as to allow of theinsertion of the ends of the main wires between therolls, and to produce a greater or less friction upon said wires to properly feed the wires forward into the machine, as willbe hereinafter more fully described.

To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail.

In the drawings, E represents the frame-wor k of the machine, which is secured to a section of d ioring or base.

G represents the bed-plate of the machine, which is slotted out to receive the difierent portions of said machine which project below the upper surface-line of the bed-plate, and is also provided with downwardlyprojecting bearing or hanger parts GG ,in thelowerends of which are fitted to turn the ends of a rock-shaft, H, to which the lower end of the rocking head M, which supports the barb cutting and feeding 8o mechanism, is attached.

, I represents the main driving-wheel of the machine, which is secured to the end of a horizontal shaft, J, arranged to turn in bearings J J, secured to the bed-plate G of the machine.

Driving-power may be imparted to wheel I by proper connection with any suitable and convenientdriving mechanism arranged above or below the flooring.

Upon horizontal shaft J are also secured cams K and L, the former being arranged to operate block or head M, before referred to, upon which the barb-wire feeding and cutting mechanism isarrangedand secured, and the latter to operate the block or head S, upon which the barb wrapper or coiling device of the machine is arranged, both of said blocks or heads being arranged to rock back and forth, as hereinafter described.

Bevel-gear N and small spur-gear O are also secured upon driving-shaft J. Bevel-gear N is for the purpose of engaging with and driving a corresponding beveled gear, N, secured upon the end of a horizontal shaft, P, arranged to turn in suitable bearings, P P, secured to bedplate Gr. Upon said shaft P are also secured a large spur-gear, Q, and a cam, R. Spur-gear Q is for the purpose of operating the harbwrapping spindle S, which is arranged to turn in the upper part of rocking arm S, being provided with teeth a, which engage with the teeth ct upon spur-gearQ. Said wrapper is also pro vided with a pin or lug, b, which catches and wraps the barb-wire 3 about the main wire 1 to form the barb, as hereinafter more fully described. v

The feed-rolls T T are operated by means of spur-gear 0, through spur-gear U, arranged to turn upon a suitable bearing secured to bed G, spur-gear U, secured upon the outer end of the shaft V of thelower feed-rolls,.TT, spur-gear W, also secured upon shaft V, and spur-gear W, secured to the shaft V of the upper feedrolls, T T.

Shafts V V are arranged to turn in suitable bearings formed in side supports or standards, V V secured to bed-plate G.

The upper feed-rolls, T '1", are formed upon the ends of a cylindrical sleeve or barrel, T, which, with the parts connected therewith, are fitted to turn loosely upon an eccentric-shaft, V. Thus by turning shaft V, which may be done by means of a hand-lever, V secured to the end of the shaft, an eccentric motion is imparted to the feed-rolls to slightly raise the same. when desired, for the purpose of inserting the ends of the wires between said feedrolls.

The necessary pressure upon the wires to properly feed them forward into the machine may be produced by means of a strong spring, X, or other suitable spring or device for depressing the ends of the eccentric-shaft V.

Y represents an adjustable guide, provided with holes 0 c for the passage of the wires, and

which may be adjusted laterally by means of turning nutsd d, so as to properly guide the wires in between the feed-rolls T T, should such adjustment become necessary, as the rolls become worn away at one point by longusage.

(Jam It upon shaft P is for the purpose of operating at each revolution of shaft P the barb-wire feeding and cutting mechanism of the machine, which operation is performed in the following manner: Upon swinging block or head M are arranged to turn two feed-wheels, Z Z, and to the hub or side of the lower and larger feed-wheel, Z, a ratchet-wheel, e, is secured, and a swinging arm, f, is arranged to turn upon the shaft of the same. Upon the inner side of the rear end of swinging arm f, and arranged to catch into the teeth of ratchetwheel 6, is hinged a ratchet pawl or dog, g, which is pressed down so as to catch into the teeth of wheel 6 by means of a spring, h, which is secured above said pawl or dog to swinging arm f. The forward end, f, of swinging arm f is made to bear constantly against the peripheryv of cam R by means of a spiral or other spring, 70, secured at one end to the rear lower end of swinging arm f and the other end to the part G of bed Gr. Driving-power is imparted from the lower feed-wheel, Z, to the upper one, Z, by means .of a spur-gear, l, secured in this instance to the side of said feed-wheel Z, which engages with another spur-gear, m, secured to the side of feed-wheel Z. The upper feed-roll, Z, is arranged to turn upona loose an gular-shaped spindle, n, which is held in position vertically by means of a cam-lever, o, hinged at the point 0 to block or head M, and longitudinally by the form of the spindle, and the rear end of the same being also hinged to block or head M at p. The lower end of lever 0 is cam-shaped, and a flat upwardly-curved s rin 0 is arran ed between said cam and the top of spindle n, so that when lever 0 is swung over in the direction shown by Fig. 3 of the drawings said spring is depressed, thereby forcing the feed-wheel Z to press with sufficient power upon the top of the barb-wire to properly feed the latter forward when the rolls are in motion. Supposing the lever 0 to be in the last-named position, from the foregoing-described construction and arrangement of the feeding mechanism it will be seen that by now rotating cam R from right to left (the direction in which the machine rotates it) it is brought in contact with the forward end, f, of swingingarm f, depressingthe same, and thereby raising its rear end, which causes pawl or dog gto catch into one of the notchesin ratchetwheel 6 and turning the latter, with its feedwheel Z and Z, as before explained, thus feeding the barb-wire forward the distance that cam It causes the peripheries of feed-wheels Z and Z to travel. Cam R is made with two slots, R and R one of which is just suflicient to allow its beingslipped over shaft P, and the other of the proper width to receive the adjustingscrew R by means of which the cam is secured to the side of the cog-wheel Q. By this construction and arrangement of parts cam it can be quickly removed by removing screw R and can also be readily adjusted to give a greater or less throw or motion to arm f by simply loosening holding-screw R and moving thecam R out from or toward shaft P, as the case may be, and then tightening up screw R again, which latter, together with the support which the forked ends of cam R receive from shaft P, insures the holding of cam B in a perfeet manner during the operation of the machine.

in this instance cam R is made shell form on its outside. Thereby lightness and strength are combined, and such a construction and arran gement of parts obtained as enables the operator to adjust the barb-feed very accurately, and which shouldfeed the barb-wire forward a sufficient distance to allow ofits being wrapped twice around the main wire 1, leaving a sufficientlength at each end, when out off, to form the barbs. The stationary cutter q of the machine is arranged in a stationary block, 4, formed upon ICO or secured to bed-plate G. Saidcutter may be adj ustedlaterally by means of adjustin g-screws s s and longitudinally by means'ot' a screw, t. (See Fig. 4)

The movable cutter u is arranged in swinging block or head M,and may also be adjusted laterally and vertically'by means of screws 11 v and longitudinally by means of a screw, 20.

Cams K and L on driving-shaft J are relatively formed and arranged to give to their respective swinging heads or blocks variable motions.

The form of cam L causes the end of the wrapping-spindle S to keep a little in advance ot'the movable cutteruuntil the barb is wrapped about the main wire 1 by the wrapping pin or In g b,when it then retreats, and the cutter c'ontinues to advance until the barb is cut by its passing over the edge of the stationary cutter q. Spur-gear Q, is made broad. whereby teeth at always remain in mesh therewith, although having a forward-and-backward motion with 1 wrapping-spindle S.

Swinging block or head M and the-arm S, upon which the wrapping-spindle S is arranged, are caused to constantly press against their respeetive cams K and L by means of flat springs K and L, secured to cross-bar E, which is, in turn, secured to frame E.

In order that the wire may be out upon an angle so as to form a pointed barb, such as shown in Figs. 6 and 7, the barb-wire rest or anvil in front of the stationary cutter q is inclined downward from the main wire 1 toward the feed-rolls Z Z; and in order to keep the wire down in position for obtaining such a cut, a holding-guide, as, provided with a hole, y, for

the passage of the wire, and hinged upon the end of a swinging lever, z, fulcrumed at the point4, is provided. Said guide is arranged to press upon the wire at the time it is being cut by the outer end,z, which is curved down, as represented in Fig. 2, bearing upon a roll, 5, arranged to turn upon the end of arm 6, which is secured to bed-plate Gr, thus acting as a cam to depress said guide at.

The outer curved end, 2, of swinging lever z is made to bear upon the periphery of roll 5 by means of a spiral spring, 7, one end of which is secured to the upper end of swinging guide 00, and the other end to the end of an upward] y and outwardly projecting arm, 8, secured to the top of swinging block or head M. By this 5 cilitated by the barb-wire being held perfectly arrangement of spring 7 ,which forces the lower end of the guide in toward swinging block or head M, the guide is made to serve the purpose not only of holding the wire in position while being cut, but also topress it against the end of spindle S during'the wrapping operation, thereby insuring the catching of the wire by the wrapping-pin 'b. t

The wrapping operation is still further fataut and secure during said operation from drawing forward through the feed-rolls by being pinchedat 9, where it is guided into the machine from the reel. Any suitable device for this purpose may be employed. In this instance a lever, 9, is used, which is hinged at the point 10, and held down by a flat spring, 11, underneath, being raised during the feeding operation by a cam, 12, secured upon driving-shaft J. The pressure upon the wire may be varied by means of an adjusting-screw, 13. If such an arrangement were not provided, the process of wrapping the barb about the main wire would be imperfect, inasmuch as the wire would draw forward and become slack, thereby producing uneven and imperfect barbs.

The barb-wire 3 passes over the main wire 1, and is wrapped around the latter from right to left toward the end of the spindle. In ordertthat it may be properly wrapped Without binding, the cam L, operating said spindle, is formed so as to move the latter forward a little slower than the wire 1 is fed forward by its feed-rolls T T, since, if they move forward with the same velocity, it will be seen that each coil would be liable to be lapped over or covered by the succeeding one, thereby producing unsatisfactory results.

The barbed wire 1 is guided and kept in position so as not to catch and become retarded in its forward movement from where the barbs are put on to where the Wires 1 and 2 are twisted together, first by a wheel or roll, 14,

pressing upon the Wire, which is arranged to turn upon the end ofa swinging arm, 15, hinged at 16, and held down by a flat spring, 17, secured at the point 18, and then by passing through a flat rectangular-shaped slot or opening, 19, (see Figs. 4 and 5,) formed by the sides '20 ot' angular-shaped block 21 and plates 22 and 23, the former being fitted in the bottom of slot 19, formed in angular-shaped block 21, and extendingforward nearly to roll 14, and the latter over the top of said slot and extending forward, as represented in Fig. 4. By this arrangement the wire and its barbs are prevented from turning between the points mentioned, thereby effectually insuring the proper movement of the same.

Plate 23 is fitted loosely and held in position by a clamp, 24, thus allowing of its ready re- .moval when desired.

In order that the main wire 1 may come at the proper level for cutting the barbs by cutters to and q, a groove, 25, (see Fig. 1,) is formed under the wire, extending to slot 19 in block 21, which also serves to assist in keeping the barbed wire in its proper position as it moves forward. a

26 is an angular plate securedto the top of block 0", which fits over the end of wrappingspindle S during the latter part of the wrapping operation, and serves to prevent the barb from being drawn back by the wrapping-pin I) when head or block S, which supports the wrapping device, recedes.

The driving-pulley I, which in this instance is secured to shaft J so as to turn loosely thereon, except when clutched to hub 1 fast on shaft J, may be clutched or unclutched to or from hub 1 fast on shaft J, or any other convenient mode of communicating the driving-power may be adopted. In this instance, as before stated, a clutch device is used for that purpose and operated by sliding arm 27 and lever 27.

The operation of the machine may be briefly summed up thus: Having put the machine in operation, the attendant first raises feed-rolls T T, as before explained, then inserts the end of wire lthrough its hole in guide y, and pushes it forward between its feed-rolls through the hole in the wrapping or barbing tube S, thence on under roll 14 and between plates 22 and 23 to the rear of the barbin g part of the machine. He then lowers the upper feed-rolls, T T, after which he passes the end of the barbwire 3 through a hole in guide-piece 9 and.under clamping-lever 9, thence forward between its feed-rolls Z Z, through swinging guide at,

I and into position, as indicated in Fig. 3 of the drawings; then starts the machine, taking hold of the end of wire 1, drawing it with sufficient tension to keep it taut until a sufficient length of wire has been barbed to enable him to fasten the end to the spool of the spooler, when the machine is stopped,and the attendant raises feed-rolls T T again and takes the en d of wire 2 and passes it through its hole 0 in guide Y, and thence between the feed-rolls and forward upon the outside of guide-roll 66, arranged upon standard 67, and upon the inside of another guide-roll, 68, upon plate 23, thence forward over the sprockets of the sprocket-wheel of the spoofing-machine with wire 1, and fastens it to the spool to which wire 1 has already been fastened. The feed-rolls are new lowered and drive-wheel I unclutched, when the twister part of the machine is started and allowed to run until the two wires are properly twisted together between the sprocket-wheel and the barbing part of the machine, after which driving-wheel I is thrown into clutch, and the machine is then in full operation, the main wires 1 and 2 being drawn from .their respective reels or spools, supported upon suitable stands arranged at proper distances from the machine, and the barb-wire also drawn from a spool or reel supported in a similar manner.

It frequently happens during the operation of a wire-barbing machine that one ofthe main wires breaks or is found defective, so that a piece has to be cut out; and to expedite the operation of securing the ends of the wires together when thus cut or broken, and also when the end of a new reel or coil of wire, 1 or 2, is to be connected to the end of the coil run out, a wire-splicing machine, F, is attached to my inachine,.and which wire-splicing device-is constructed as follows: A short hollow shaft, 69, provided with a slot, 73, and with turninghandles 70, is arranged to turn in bearings formed in the upper ends of upright side supports or standards; 7l 71, which are also provided with slots 73 73, and to the outer sides of said standards 71 71 are secured two other stationary holding-pieces, 72 72, provided with slots 72 72. In splicing two ends of wire to gether hollow shaft 69 is turned to bring its slot in line with the slots 73 and 72, as indicated in the drawings, and then the wires are placed in said slot with one wire lapped or placed over the other, the ends of the wires being lapped and extending in opposite directions, the end of each wire extending a short distance beyond its respective end of the device, and in which it is held from turning or twisting about the other end of the wire, since slots 72 are only wide enough to receive a single strand of wire.

The center of slotted shaft 69 is provided with a set of holding jaws or teeth, 74, which are set just far enough apart to leave a slot corresponding to-the width of the slots 72. Consequently, when tubular shaft 69 is rotated .by means of handles 70, the wires will be carried around by the jaws or teeth 74' and the ends of the wires twisted together on each side of said teeth or jaws, such twists extending from the sides of the jaws or teeth 74 in opposite directions to the inner sides of slotted pieces 72. After the ends of the wires have been twisted together, as above described, by means of this splicing device, the attendant turns tubular shaft 69 so as to bring the slots all in line again, after which, by a slight upward pull on the wire, the latter is removed from the splicing device, the slots 73 and 73 being wide enough to allow the twisted and spliced portions of the wires to be lifted out or withdrawl'l freely.

Those skilled in the art to which my invention belongs will readily perceive and understand the practical advantages necessarily resulting from my present invention. The main wires 1 and 2 having a continuous and uniform longitudinal or forward motion during the operation of the machine, all the noise; and straining of the parts of the machine incident to or resulting from the constant stopping and starting of themain wires, or the parts which feed them forward, are obviated by my improvements hereinbefore described, while at the same time the improvements referred to render the operation of barbing, twisting, and spooling the wire very expeditious and uniform.

Having described my improvements in wire barbing, twisting, and spooling machines, what I claim therein as new and of my invention, and desire to secure by Letters Patent, 1s
