BARBED-WIRE MACHINE.

SPECIFICATION forming part of Letters Patent Bio-608,471, dated August 2, 1898. 1

Application fihgdDecember 23,1897. Serial No. 663,197. (No model.)

To all whom it mag concern:

Be it known that I, BENJAMIN M. MILLER, a citizen of the United States, residing at Orawfordsville, in the county of Montgomery and State of Indiana, have invented a new and useful Barbed-Wire Machine, of which the following is a specification.

My invention relates to improvements in machines for producing barbed wire in which I have so combined and arranged the barb-applying mechanism as to equalize the strain on the longitudinal strands during the operation of applying Wire barbs thereto.

A further objectthat I have in view is to provide an improved machine by which the barbs are applied to the longitudinal strands simultaneously at alternate intervals and at proper distances apart, thus increasing the capacity of the machine and enabling the barb applying mechanism to be run at a slower speed.

A further object that I have in view is to so construct the machine that the barbs may be applied to the longitudinal strands at intervals, which may be regulated as desired that is to say, the barbs may be attached to the strands at intervals of either three inches or six inches apart-and such adaptation of the working elements of the barb-applying mechanism may be effected within a few minutes time and withoutinvolving stoppage of the machine to make the necessary changes,

thus overcoming a serious objection to prior barbing-machines which require two or three hours labor to make the necessary changes in the working parts thereof.

With these ends in view my invention consists in the combination of a pair of revoluble strand-carrying shells having their barb-coil-.

ing intermittent motion to said feed mech-{ anisms for the barb-forming Wires, and a takeup mechanism for feeding the barbed strands at suitable intervals; and the invention further consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed. I

To enable others to understand my invention, I. have illustrated the same in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a planview of a wire-barbing machine embodying my invention. Fig. 2 is an elevation taken from the right-hand side of the machine shown by Fig. 1. Fig. 3 is a similar side elevation taken from the left-hand side of the machine shown by Figs- 1 and 2. Fig. 4 is an end elevation looking at the righthand end ofthe machine illustrated by Fig. 1. Fig. 5 is an elevation of the barb-applying mechanism, the independent feed mechanisms, and the driving mechanism for said independent feed mechanisms, looking at the left-hand end of the working parts shown by Fig. 1 and illustrating a part of the foundation-frame in transverse section. Fig. 6 is a transverse sectional view on the plane indicated by the dotted line 6 6 of Fig. 1, look ing in the direction indicated by the arrow.

'Fig. 7 is a detail sectional elevation on the plane indicated by the dotted line 7 7 of Fig. 1, illustrating the gearing by which the strandcarrying shells are rotated and the gearing between the upper and lower sets ofrolls forming in part the independent feed mechanisms to supply separate strands of barbforming wires to the coiling-fingers of the the means by which the reciprocating motion v is given to the inner members of the oppositely-rotating strand-carrying shells. Fig. 11 is a detail fragmentary view of the driving mechanism for impelling the lower shafts of the independent feed mechanisms for the barb-forming wires. Fig. 2 is a detail fragmentary view in elevation of the reciprocating devices by which reciprocating play is given to one of the lmtterlly-wheels forming a part of the take-up mechanism by which the longitudinal strands are drawn or fed through the machine.

Like letters and numerals of reference denote corresponding and like parts in each of the several figures of the drawings.

A designates the horizontal framework of the machine, which is supported by suitable legs or standards a, firmly fastened to the floor. This main frame A sustains all of the working elements of the machine, and upon it mounted the bed-plate 13, which carries the barb-applying mechanisms.

Arranged longitudinally of the main frame A and beneath the horizontal part thereof, upon which the bed-plate 13 is supported, is the revoluble twister-frame 1. At one end of this revoluble twister-frame it is provided with a bearing-annulus 2, loosely journaled on a ringbearing 3, attached to the legs or standards a at one end of the frame A. The other end of this revoluble twister-frame is supported by a horizontal power shaft 4., which is journaled in a suitable bearing in the legs a at the opposite end of the main frame A, and said power-shaft lprotrudes beyond the machine-frame to receive the fast and loose pulleys 5 (3, by which the machine is driven. The revoluble twister-frame is provided with journal-bearings 7 to receive the shaft 8 of a reel 8, and to said reelshaft is secured a beveled gear 9, with which meshes a beveled pinion 10 on a horizontal shaft 11, suitably journaled on the twisterframe 1, said shaft 11 being geared through the train of gears 12 to the power-shaft 1, whereby as the frame 1 is rotated the reel will also be rotated within said frame for the purpose of winding thereon the barbed wire as it is produced by the machine.

As is usual in this class of machines, the revoluble twister-frame 1 carries a non-rotatable threaded arbor 12), on which is screwed a guide-traveler ll, adapted to direct the barbed wire along the revolving reel 8 and to insure proper and uniform coiling of said barbed wire on said reel.

15 designates the main driving-shaft, which is arranged in a horizontal position longitudinally of the frame A and above the bedplate I This shaft 15 is journaled in suitable bearings provided in the standards 10, which are attached to the bed-plate l3 and to an extension b at one end of said bed-plate, and this main driving-shaft carries means for driving the strand-carrying shells, a crankdisk for the independent feed mechanisms, a cam for giving reciprocating motion to the inner members of the stra1nl-carrying shells, and a cam for actuating a reciprocating knifecarrying block, all as will hereinafter fully appear.

Erected on the bed-plate 1 in a position transversely across the machine is a fixed upright 17, which at its upper part carries a housing or casing 18, adapted to contain the revoluble strand-carryin g shells 1.9 20. These strand-carryin g shells are arranged parallel to each other in substantially the same horizontal plane, and one shell, 20, is longer than the other shell, 19, so as to have the working ends of the short shell terminate at a suitable distance in rear of the corresponding end of the othershell 19. The shell 1 f) has an outer rotary member 19 and an inner rotary and reciprocating member 19. In like manner the long straml-carrying shell 20 consists of an outer rotary member 20* and an inner rotary and reciprocating member 20". The outer members of the long and short strmnl-carrying shells are journaled in suitable bearings provided in the upright 1.7 and housing 18 in a manner to be free to rotate axially therein, but said outer members of the strand-carrying shells are limited to rotary motion. The inner members 10" and 20", however, are arranged within the outer rotary members in a manner to have limited eudwise or reciprocating motion within said outer members of the shells, as well as to be rotated axially by connectionsbetween the outer shells and said inner shells.

The two strainl-earrying shells are designed to be driven in opposite directions simultaneously by means of gear-pinions 21 22, which are secured rigidly on the outer members of the shells, said pinions being housed within the hood or casing 18. The strand-carrying shells being arranged parallel to each other, the pinions 21 22 mesh directly together to insure opposite rotation simultaneously to the straml-earrying shells, and with the gearpinion 21. of the short straml-carrying shell 19 meshes a large driving-gear 23. This driving-gear is mounted loosely on the main driving-shaft 15 to rotate independently thereon, and with this driving-gear meshes an intermediate idler-gear 2-1- on a short shaft 25, journaled in suitable hearings on the bedplate 13. This shaft is in turn driven by a counter-shaft 20, having a pinion 26, which meshes with the pinion 21-, and said countershaft 26 is journaled in hearings on the main frame of the bed-plate at the left-hand side of the machine, so as to lie parallel to the main driving-shaft 15, but at a suitable distance below and to one side thereof, said counter-shaft being geared directly to the driving-shaft 15 through the intermeshing gears 27 28, which are fastened rigidly to the counter-shaft 2 and the main driving-shaft 15, respectively. It will thus be seen that I have provided a train of gears in connection with counter-shafts by which the strand-carrying shells are rotated positively in opposite directions and that said train of gears in shells.

cludes two gears 28 23, which are fast and loose, respectively, on the main driving-shaft 15. The inner members 19 and 20 of the revoluble strand-carrying shells are fitted snugly within the outer members 19 and 20 of said shells, so as to rotate therewith and to be free to have a limited endwise movement therein, and the rear ends of said inner members of the strand-shells are projected or extended beyond the corresponding ends of the outer members of said shells to provide for the connection therewith of the means by which the reciprocating motion may be imparted to the inner members of said strandcarrying shells.

In Fig. 8 of the drawings I have illustrated the projecting or extended ends of the inner strand-carrying shell members as. provided with annular grooves 29, and in these grooved extended ends of the inner shell members are fitted the sl1ipper-forks30 30. Said shipperforks loosely embrace the grooved extended ends of the inner members of the strand-carrying shells to permit the latter to rotate freely within said forks, and the forks are mounted loosely in the arms of a swinging frame 31, arranged in a vertical position alongside of the upright 17, the lower end of said swinging frame being pivotally attached, as at 32, to lugs or ears 32: of the bed-plate B. The shipper-fork 3O is carried by a shaft 33, which is journaled in a bearing formed by one of the arms of the swinging frame 31, and on this shaft 33 .is rigidly mounted a loose tappet-wheel 34, which works in a kerf or recess 34, provided in said frame 31. Said loose tappet-Wheel 34 rides against the face of a cam 35, secured rigidly on the main driving-shaft 15 in a position alongside of the large drivinggear 23,, by which motion is imparted to the strand-carrying shells. (See Figs. 1, 2, 3, and S.)

The swinging frame 31 has a stud 35, to which is fitted a coiled pressure-spring 36, seated against a suitable projection on the bed-plate B, said spring tending to normally force the frame 31 toward the shells 19 20;v

but in the revolution of the cam-wheel 35 its eccentric or cam face rides against the tappet-wheel 34 to positively move the frame 31 and carry with it the forks 3O 30 to impart the reciprocatory or endwise movement to the inner members of the strand-carrying strand-carrying shells have integral heads 37 38, in which are formed central openings 39, while the outer members 19 and 20 are prov vided with the face-plates 4O 41,respectively,

said face-plates having openings 42, which are in axial alinement with the openings 39 in the inner members of said shells, whereby the strand-wires are adapted to pass through said shells 19 20. Said inner members 19 and 20 of the strand-carrying shells are further provided with the'coiling-fingers 43 44, which fingers are rigid or, integral with the, heads of said inner members of the shells and are The inner members 19 and 20 of the inner members of the strand-shells are moved endwise toward the face-plates on the outer members of said shells, the coiling-fingers 43 44 are projected a suitable distance beyond the face-plates 4O 41 for the coiling-fingers to properly engage with the lengths of wire whichare to be twisted around the longitudinal strands to form the barbs thereon; but when said inner members of the shells are retracted by the action of the cam-wheel 35 the barb-coiling fingers 43 44 are drawn within the face-plates, so as to be out of the way of the longitudinal strands or the barb-forming wires supplied by the feed mechanisms, thus arranging the barb-applying mechanism to avoid interference with the proper feed of the longitudinal strands through the machine.

By reference to Figs. 1 and 8 it will be seen that the longitudinal strands are fed through the machine and the strand-carrying shells 19 20 in planes parallel to each other, each wire being separate and distinct from the other or companion wire during its progress through the major portion of the machine and through the strand-carrying shells 19 20;

but after the barbs have been applied to said longitudinal strands they are caused to approach each other and to travel in close relation to if not in actual contact with one another around the butterfly-wheels, which direct the barbed wires to the revoluble twister-frame 1, the action of which twisterframe is to insure the intertwining of the hithertoindependent strands previous to the coiling of the twisted strands upon the reel 8.

The wires forming the longitudinal strands are supplied from suitable reels, (not shown,) and they are led or directed by and between idler-rolls 46, situated at one end of the machine-frame and carried by suitable arms 47 attached to the horizontal rails of the main frame A. The butterfly-wheels just mentioned constitute the take-up mechanism between the strand-carrying shells and the revoluble twister-frame,'and such take-up mechanism will be hereinafter more fully described.

I will now proceed to describe the barbedwire-feedin g mechanisms by which independ ent wires are fed from opposite sides of the machine in Eproper positions to the working ends of the long and short strand-carrying shells 19 2O forthe engagement of the barbcoiling fingers with the short lengths of wire adapted to be cut from the barb-forming ICO IIC

wires and to be coiled by said fingers around the longitudinal strands to produce thereon the barbs at the proper intervals.

The barbed-wire-feed mechanism D for the short shell 19 is arranged on the left-hand side of the machine, while the corresponding feed mechanism C for the long strandcarrying shell 20 is situated on the opposite or right-hand side of the machine, as shown by Fig. 1. Said wire-feed mechanisms are independent of each other, but they are designed to be driven by a common driving mechanism, which propels the feed-rollers of the two feeding mechanisms at a uniform peripheral speed in order to feed equal lengths of wire to the cutter mechanisms and to the working ends of the coiling-fingers of the straml-carrying shells. Each feed mechanism is constructed in substantially the same way, and a description of one will apply equally as well to the other. Each feed mechanism consists of a lower shaft 50, journaled in suitable fixed bearings on the bedplate B, a pivoted frame 51, provided with a housing 51, an upper shaft 52, journaled in said housing and carried by the swinging frame, gear-wheels 53, attached to the shafts 5052 to communicate the motion of the lower shaft 50 to the upper shaft 52, and rollers 54 55, fastened rigidly to the shafts 50 52 and arranged in the same vertical plane in order to grip the wire as it passes through the feed mechanism. The feed-roller on the upper shaft 52 is normally pressed downward into contact with the roller 54: on the lower shaft 50 by means of a spring-arm 56, attached to the pivoted frame 51, a stem 57, connected to said spring-arm 5G, and to an eccentric-collar 57, a coil-spring 5S, fitted upon said stem 57, and a shaft 59, journaled in bearings on the bed-plate and provided with an eccentric 60 and with an operating-handle 60, said eccentric-collar 57 fitting around the eccentric 60. By moving the lever (30 in one direction the shaft 50 may be rocked to ease up the tension of the spring 58 of the pivoted frame 51, which carries the upper feed-roller shaft; but by depressing said lever the tension of the spring on the swinging frame may be varied as desired to impartthe necessary frictional grip between the feed-rollers 5-1 to properly engage with the wire from which the barb is formed.

The feed-roll shaft 50 of the feed mechanism D on one side of the machine is provided with a ratchet 61, while the lower feed-roll shaft 50 of the other feed mechanism C on the opposite side of the machine is provided with a similar ratchet 62. On said feed-roll shafts 50 of the independent feed mechanisms are loosely hung the swinging arms (53, which lie adjacent to the ratchets 61 62 and extend in opposite directions from the shafts 50 of said independent feed mechanisms. The

swinging arm 63, which projects above the shaft 50 of the feed mechanism D, carries a pawl 65, arranged to engage by gravity with the ratchet 01, while the other arm 63, which lies below the shaft 50 of the feed mechanism 0, has a spring-controlled pawl (54, that is normally pressed into engagement with the ratchet 62 of said feed mechanism. Vith the arm (33 of the feed mechanism 0 is pivotally connected a driving-link 66, and the other end of said driving-link is pivoted on a wrist-pin 67, carried by a crank-disk 68, which is secured on the main driving-shaft 15. To the driving-link 06 at a point intermediate of its length is pivoted, as at 69, a driven link 69, the other end of which is attached, as at 69", to the arm 63 of the feed mechanism D. As the crank-disk 68 rotates with the shaft the links 69 are reciprocated to swing the arms During one stroke of the links the pawls on the arms 63 engage with the ratchets 0f the shafts 50 of the feed mechanisms in a manner to rotate the feedrollers 5t 55, but during the other portion of the rotation of said crank-disk 68 the links 66 69 operate the arms 03 in a reverse direction to allow the pawls to slip idly over the ratchets 61 62, whereby the feed mechanisms remain at rest during the intervals when the coiling-fingers operate to attach the barbs to the longitudinal strands.

In connection with the intermittcntly-actuated feed mechanisms I employ the guides 7 O 71, which are suitably attached to the bedplate B in positions transversely across the machine and out of line with each other, each guide consistin gof a channel or trouglrshaped metal piece. The guide 70 leads from the feed-rollers to the feed mechanism C to a point adjacent to the working end of the short strand-carrying shell 1!),while the other guide 71 is situated between the feed-rollers of the feed mechanism D and the working end of the long strand-carrying shell 20, whereby said guides are properly disposed with relation to the strand-carrying shells to supply the barb-forming wires to said strand-carrying shells at the proper intervals for application to the longitudinal strands at alternate points thereto.

I will now proceed to describe the cutter mechanism, which is actuated from the main drivingshaft 15 at suitable intervals and which is constructed to sever short lengths of wire from the two strands fed to the working ends of the shells 19 20 by the operation of the independent feed mechanisms. This cutter mechanism is situated adjacent to the working ends of the long and short strandcarrying shells and between the feed mechanisms for the barb-formin g wires, substantially as shown by Fig. 1. Said cutter mechanism comprises in part a swinging carrier-block 73, which is shaped irregularly to present surfaces adjacent to the working ends of the long and short straml-carrying shells 1f) 20, and said swinging carrier-block is hung or pivoted at a point intermediate of its length, as at 74:, on a standard 74E of the bed-plate B. One end of this swinging carrier-block is IOC constructed to form a fork 75, which loosely embraces a cam or eccentric 76, secured on the main driving-shaft 15, whereby the carrier-blockis positively and-automatically reciprocated-by motion derived from the shaft 15.1 On this carrier-block are secured movable knives 77, which operate in connection with the stationary knives 78, bolted or otherwise fastened to upright posts 78 rigid with the bed-plate B. The knives 77 and "78 are arranged .in pairs contiguous to'the working ends of the long and short strand-carrying shells, and said knives are arranged or constructed to sever the short lengths of wire from the barb-formingwires supplied by, the feed mechanisms with a shear cut for the purpose of producing the proper points on the barbswhich are applied to the longitudinal strands. I 7

It will be seen that the carrier-block is ac tuated automatically by connections with the main driving-shaft 15, which are so timed and arranged that the movable knives on said carrier-block will be brought into operative relation to the fixed knives 7 8 to cut or sever the wires supplied by the feed mechanisms subsequent to the operation of twistingthe barbs around the longitudinal strands by the action of the coiling-fingers in the strandcarrying shells, and it will also be observed that the independent sets of knives are ar-. ranged in such relation to the guides 71 and the working ends of I the long and short strand-carrying shells that the wires supplied by the feed mechanisms will be cut 0% at proper distances suflicient to form the barbs.

I will now proceed to describe the take-up mechanism by which the longitudinal strands are fed intermittently through the machine.

The main driving-shaft 15 projects at one end through its bearing in the extreme pillowblock 16 to receive a beveled gear-pinion 80, with'which meshes a beveled gear 81, secured rigidly on a shaft 82, which is journaled in suitable bearings provided in the standard 83, mounted on the extreme right-hand end of the frame A. At one end this shaft 82 is provided with a crank-disk 84, having a wristpin or crank 85, adapted to play in the vertical slot 86 of an arm 86, the upper end of .which is pivotally attached, as at 86 on a part of the machine-framework, whereby the vertically-slotted arm 86 is adapted to be reciprocated by the crank-pin on the shaft 82, geared directly to the main driving-shaft 15. This slotted arm 86 has a pendent lug 86, through which passes a guide-stem 87, suitably supported in a lug 87 on the machine- ,frame, and said guide-stem carries a coiled pressure-spring 88, which is held inplace by the guide-stem,one end ofsaid pressure-sprin g being seated against the lug 87 and its other end against the pendent arm 86 of the vibrating slotted arm 86. Said slotted arm 86 is further provided with a journal pin or stud 88, on which is loosely mounted an idler butterfly-wheel 89, which is'free to rotate on the stud 88 of said vibrating arm, and which is carried in a positive. manner back and forth with the vibrating arm 86 as the latter is moved by the crank-disk 84, whereby the butterfly-wheel 89 is adapted to strain orpull 011 ,the longitudinal strands at suitable intervals after the barbs have been applied to said strands. v

90 designates a continuously-rotated butterfly-wheel which is arranged below the idler butterfly-wheel 89 and in a line slightly in advance of said wheel 89. This continuously rotated wheel 90 is rigidly secured to one end 7 of a shaft 91, j ournaled in bearings of a hanger 91, rigid with the machine-frame. ,S aid shaft is provided at its opposite end with a gear 92, i which meshes with a gear-pinion 93, journaled on a stub-shaft 93, supported in a pendent arm 93. sprocket-pinion 94, around which passes a sprocket-chain94 that extends up to and is driven by a sprocket-pinion 94c on the shaft stantially the same vertical plane as the vibrating wheel 89.

V This idler-wheel 95 is journaled on a stud 95 rigid with an upright 96, pivoted to the floor, as shown by Figs. 2 and i, and to the upperend of this standard 96 is attached a guide-stem 97, suitably and Rigid with this gear-pinion 93 is a loosely connected to the main frame A and" sustaining a coiled pressure-spring 98, which is seated against said. pivoted standard 96 for the purpose of pressing the latter and the idlerwheel 95 away from the continuously-rotated Wheel 90.

My takeupmechanismembodies two idler wheels 89 95, situated in horizontal planes on opposite sides of a continuously-rotated butterfly-wheel 90, and one idler-wheel is normally pressed away from the wheel 90, while-the other idler-Wheel is reciprocated for the purpose of straining the strand-wire at suitable intervals to enable the continuously-rotated wheel to .pull on the strandwire and-effect the proper feed thereof through the strand-carrying shells 1920 of the machine. v Y

When the reciprocating idler-wheel 89 of the take-upmechanismis moved in a direction toward the strand-carrying shells,.acertain amount of slack is permitted in the longitudinal strands, which slack is taken up by the action of the continuously-rotated wheel in the interval when the shells 19 2O andthe barb-coiling fingers are actuated to twist the barbs around the longitudinal strands but as the arm 86 moves the idler-wheel 89 away from the strand-carryin g shells the longitudinal strands'are strained and the rotation of the wheel 90 draws on the strands to effect the proper feed or movement of the latter through the shells 19 20 a suitable distance to present new surface on the longitudinal strands for the application of the barbs thereto.

The main driving-shalt 15 is geared to the horizontal twister-frame l by the gearing illustrated in Figs. 2, 3, and 4-. This gearing comprises a sprocket-wheel 90, which is fast with the annulus 2 at one end of the twister-frame 1. On the main frame A is a fixed stub-axle 100, that carries a compound sprocket-wheel 101,0ne part of which sprocket wheel is in alinement with the sprocket-wheel 90, to be connected therewith by a sprocketchain 102. The other part of the compound sprocket-wheel 101 is in vertical alinement with the sprocket-wheel 103, fastened rigidly to the main driving-shaft 15,and the sprocketchain 101- passes around said member of the compound sprocket 101. and the sprocket 103 to operatively conneet,through the compound sprocket 101, the shaft 15 with the rcvoluble twistealrame 1.

As is usual in this class of machines, the wires from which the barbs are to be formed are guided to the feed mechanisms by idler guide-rollers l0l, carried by arms 105, suitably attached to the maehine-framework.

It is thought that the operation of the invention will be readily understood from the foregoing description, taken in connection with the drawings.

It is evident that slight changes in the form and proportion of parts and in the details of construction maybe made without departing from the spirit of the invention or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes and alterations as properly fall within the scope of the invention.

Having thus described the invention, what I claim as new, and desire to seeu re by Letters Patent, is
