WIRE-BARBING MACHINE.

SPECIFICATION forming part; of Letters Patent No. 309,584, dated D cem r 4- ApplicntionfiledApril9,1883. (1\*omodel.)

To all whom it 11mg concern:

Be it known that I, HENRY M. VAUGHAN, of Newton, in the county of Jasper and State of Iowa, have invented a IVireBarbing Machine, ofwhich the following is a specification.

My object is to form and apply the fencebarb shown and described in the United States Letters Patent N o. 212, 874, issued to me March 4., 1879, by means of automatic mechanism.

My invention consists,first,in a solid non-rotating shaft to direct and retain two fence-wires relative to each other and a tubular rotating shaft and barb-coiling head; second, in a sta tionary frame for the barb-cutting mechanism, I 5 and the combination of a detachable cutter therewith that can be sharpened by simply grinding its fiat surface; third, in the construction and combination of areciprocating wire-holder with the barb-cutting mechanism; fourth, in a device for holding the parallel wires and bending and tucking the free end of the coiled barb-piece between them; fifth, in wiremoving and barb-spacing mechanism that will advance a coiled barb-piece and partially-finished barb on the parallel wires from the barb-coiler at regular intervals of time and space to the barb-tucking and finishing device; sixth, in a barb grasping and cabletwisting device that will twist the two parallel wires at regular intervals direct between each two complete barbs as they are successively advanced from the barb-forming to the spooling mechanism in such a manner that each barb will extend at right angles relative to the barbs on its opposite sides; seventh, in

a stop-motion gear to impart intermittent partial revolutions to the barb-coiling shaft and head, all as hereinafter fully set forth.

Figure 1 of my accompanying drawings is .0 a side view of my machine. Fig. 2 is an enlarged detail view of a section of my solid nonrotating wire guide and holder. Fig. 3 is a side view showing my barb in two different stages of construction. Fig. 4 shows the barb completed. Fig. 5 is a top view of the machine. Fig. 6 is an enlarged perspective view of my frame for the barb-cutting mechanism to which my detachable cutter is fixed. Fig. 7 is a longitudinal sectional view of the machine. Fig. 8 is a top view of the driving mechanism. Fig. 9 is a transverse section of Fig. 1, looking to the right from the dotted line marked 9. Figs. 10, 11, 12, 13, and 14 are transverse sections of Fig. 1, looking to the right from the respective dotted lines of corresponding numbers. oral-moving wire-holder in contact with the parallel fence-wires, as required to retain them in proper position while the barb is being tucked and finished. Fig. 16 shows the same lateral-moving wire-holder withdrawn from the fence-wires, as required to allow the partially-finished barb to be advanced with the fence-wires. tucker; and Fig. 18, a perspective view of the end thereof, that is adapted in shape to engage the end of a barb and press it through between the parallel fence-wires.

Jointly considered, these figures clearly illustrate the construction and operation of my complete invention.

Arepresentsthe frame and base upon which my various operative devices are mounted. It is preferably one solid iron casting, but may be made in sections and of wood andiron combined.

A is an extension formed on or fixed to the front end and top of the base A.

A is a tubular rotating shaft mounted on top of the extension A by means of bearings A A is a tubular barb-coiling head screwed upon the rear end of the shaft A One side of its free tubular end is cut away, so that the projecting section engages the free end of a barb-piece when it extends at right angles to the head, and to carry it forward in its rotary motion as required to coil the barb piece around the fence-wire.

A is my solid non-rotating wire guide and holder.

Heretofore longitudinal bores have been made in a non-rotating guide to direct two wires. I avoid the difficulty of making such bores by forming grooves in the outside surface of the shaft and short inclined bores a. a from the end face of the shaft to intersect the grooves in the surface, as clearly shown in Fig. 2.

Fig. 15 shows the lat-- Fig. 17 is a top View of my barb- 60 a cam-Wheel, No. 1, that is fixed to the driva is an elbow and handle at the rear end of the shaft, through which a bore, a, is made 1 to intersect the groove in the under side of the shaft.

- *5 a is a catch that engages the handle a y when the guide A is placed within the tubular shaft A, as required to prevent the guide from rotating. The catch ais made by simply forming a slot in the edge of the extension A",

or by fixing a bifurcated piece thereto. I

B (clearly shown inFig. 6) is the base or frame of my barb-cutting mechanism. It is cast complete in one piece, and has perforated flanges at its ends, through which screw-bolts r 5 are passed to fasten it on top of the base A. I

B are end pieces or benches that restrict the downward motion of the cutter-carrier operated vertically through the perforations 13 in said benches.

B areinclined faces on the front ends of the benches B. The one inclined face aids in directing the barb-piece as it is projected between the two parallel wires, and both aid in keeping the free end of the barb-piece in proper position relative to the rotating head that coils it around the two wires.

B is an inclined or triangular projection that extends inward from the front end of one of the benches B to form a bearing and sup port for the detachable cutter.

is a cutter in the form of afiat steel plate fitted to the inside inclined face of the exten- 'sion B", and fixed thereto by means of a screw.

' b is an elongated inclined orifice in the cut- 3 5 ter, that coincides with a horizontal bore extending-diagonally through the bench B and 1 extension 13*, to allow the wire fromwhich the l barbs are to be cut to be projected through the orifice Z) of thefixcd cutter.

I) is a perforation through the flat portion of the base of the frame 13, through which my reciprocating wire-holder I) (clearly shown in Fig. 10) is operated.

b are the vertical parts, and b the cross- 4 5 pieces, of a frame and cutter-carrier. The vertical parts extend through and move in the perforation B of the base 13 and benches B.

c is a cutter fixed to the under side of the I I upper cross-bar, b, in such manner that its lower cutting-edge will engage the barb-wire that projects through the orifice b of the fixed cutter B as the cutter-carrier descends.

c is a short square bar that has a screw shank at its top end to extend through the cross-bar b of the cutter-carrier and the lower end of the wire-holder b, to be rigidly connected to those parts by means of a nut, c. c is a stud that projects at right angles from the bar 0. into the continuous groove of ing-shaft O. H

0 are straight fiat bars bolted to the opposite sides of the bar 0, to extend down on the 1 opposite sides of the driving-shaft O, to guide the vertical movements of the cutter-carrier i that is elevated at every revolution of the camwheel No. 1, and also depressed sufficiently at each revolution by means of an inward bend in the continuous cam-groove in the wheel to operate the cutter as required, to cut off a barb-piece at regular intervals. The wireholder 1), thatis carried by the cutter-carrier, is bifurcated at its top end to engage and hold the fence-wires while the barb-piece is being coiled upon the parallel fence-wires before it is cut off.

d is a wire-holder (see Fig. 10) that moves laterally relative to the fence-wires at regular intervals, to allow the incompleted barbs to pass, as clearly shown in the enlarged views, Figs. 15 and 16.

d is an elbow-crank pivoted to the base A and hinged to the stud c at one end.

(1 is a lever pivoted to the opposite side of the base of the machine.

61 is a straight bar hinged to the lower end of the lever d and the lower end ofthe elbowcrank, as clearly shown in Fig. 10. The top end of the lever c is flexibly connected with the sliding wire-holder d, that is in the form of two parallel round bars, d, connected at their ends by means of angular cross-bars, as clearly shown in Fig. 5.

D is the base-piece of the barb tucking and finishing mechanism, fixed to the base A in rear of and in contact with the base-piece B of the barb-cutting mechanism. It has horizontal bores, through which the parallel round barst pass and move. As the cutter-carrier is depressed by means of the in ward bend of the continuous groove in the cam-wheelNo. 1, the

crank d, connected with the stud c in that groove, is vibrated to impart motion to the lever d, as required, to withdraw the barb holder at laterally relative to the parallel wires at regular intervals, to allow the incomplete barb to pass as the wires are jointly advanced by the spacing and reeling mechanisms.

FVhen a barb-piece is coiled upon the parallel fence-wires, it is advanced to the tuekin g mechanism to be completed, and the lateral-moving holder (1 moved outward and away from the ICC fence-wires, to allow the incomplete barb to get into a parallel position with the tucker. The holder (1 is then moved inward against the parallel fence-wires, to support them during the operation of the tucker and the completion of the barb. The base-piece D has a depressed surface, D, as shown in Fig. 12, upon which the tucker slides.

d (clearly shown in Fig. 7) is a shoulder in the surface D, against which the barb-piece rests while its vertically-projecting end is being pressed into a horizontal position by means of a barb-bender. Before the tucker is operated a barb-bender is required to press the projecting end of the barb-piece into parallel position with the parallel wires, as shown at the right in Fig. 3.

e is a barb-bender fixed to the end of a rockshaft, 0, that projects through a bore and bear- 0 is a bridle in the crank c.

0 is a reciprocating bar that is bifurcated at its top end and connected with the bridle of the crank e by means of a bolt. It has a bridle, c', extending at right angles from its bottom end, through which a crank-pin, f, extends from the side face of a rotating disk,

f, in such a manner that the rotary motion of the disk will impart reciprocating motion to the bar 6 and rock the shaft 0 at regular intervals, as required, to operate the barbbender c, and to thereby bend the barb that projects vertically, as shown at the left end of Fig. 3, into a horizontal position and parallel with the parallel wires, as shown at the right end of the same figure, neliminary to tucking it through between the feneewires and into position, as shown in Fig. -l-.

To hold the parallel wires firm while the barb is being tucked and completed, I provide awire-holding device in rear of thetucking device.

D is the frame and bearing of this auxiliary wireholder, fixed on top of the base A and against the rear side of the basepiecc D, as clearly shown in Figs. 1, 7, and 11.

Z)is a reciprocating wire-holder, construct ed as clearly shown in Fig. 11, and operated by means of the cam-wheel No. 2, fixed to the driving-shaft G in such a manner that it will retain the parallel wires in the vertical slot (that intersects an orifice at its top) whilethe barb is being tucked and completed, and then ascend to allow the complete barb to pass through the orifice as the parallel wires are advanced in the machine.

f is my sliding barb-tucker. It has a longitudinal slot, f, that is curved laterally at its rear end. It is attached to the depressed top surface, D, of the base-piece .D by means of screw-bolts f, that extend through the slot of the tucker into the base, and serve as guides in directing the movements of the tucker through between the parallel wires, and then,by means of the eurvein it,laterall y to bend the barb away from the wires.

f is a pointed projection formed on or fixed to the front end of the sliding tuekerj, to pass between the parallel fence-wires in advance of the square and grooved end of the tucker,to separate the fence wires sufficientl y for the passage of the tucker and the end of the barb carried. thereby. The body of the tucker is fiat, and its front end, adapted in shape to engage the end of a barb and carry it through between the parallel fencewires and press it into position, as shown in Fig. 4.

g is a handle fixed to the tucker to extend laterally. This handle is fiexibly connected with a lever, g, by means of a link, g, that is bi furcatcd atitsends, as clearly'shown in Fig. 12. The lever 9 extends down through an opening in the base A, and is supported by means of a fulcrum, g, fixed to the base. It has a bridle, 9, in its lower end, through which the pin of a crank, 9, extends in such a manner that the revolving motion of the crank will vibrate the lever as required to operate the tucker at regular intervals.

F is a shaft suspended across the under side of the base A by means of hangers, as clearly shown in Figs. 1 and 13.

F is a lautern-wheel in form, fixed to the middle of the shaft,-to aid in advancing the parallel wires at intervals as required, to fix the barbs thereon at regular intervals of time and space. This wheel extends up through an opening in the base A to a level with the parallel wires, that are passed around it and advanced at regular intervals relative to the barb'cutting and barb bending and tucking devices by the intermittent rotary motions of the wheel F.

No. 3 is a wheel fixed to the shaft F to perform the function of a ratchet-wheel.

F" is a pawl-bearer hinged to the shaft F at its top end and connected with agrooved camwheel, F", that is fixed to the driving-shaft G. The wheel No. 3 has a continuous groove in its side lace, as indicated by dotted lines in Fig. 1, into which the pawl 11, pivoted to and carried by the bearer F is projected in such a manner that it will clamp fast in the continuous groove of the wheel No. 3 in a forward motion of the arm or bearer F and slide therein in a reverse or backward motion as required, to impart intermittent motions to the wheel F and advance the parallel wires regular distances corresponding with the spaces between the barbs fixed thereto as the wires are jointly moved through the machine from coils supported at the front end to a reel at the rear end.

No. 4 is a ratchet-wheel fixed to the opposite end of the shaft F from the wheel No. 3.

h is a gravitating pawl pivoted on top of the base A, to engage the wheel No. 4 and to prevent any backward motion of the wiremoving wheel F and relapse of the parallel wires to which the barbs are fixed.

No. 5 is a ratchet-wheel fixed to the shaft F.

F is a pawl hinged to a post rising from the base A in such a manner that a stud on its lower end will enter a continuous groove in the wheel F and allow the shoulder in the side of the pawl to engage one of the teeth of the wheel No- 5 at each revolution of the shaft 0, to restrict the ad va ncc of the parallel wires to equal distances at each motion of the wheel No. 3.

G- is a barb-grasping and cableholding de- 7 vice fixed on top of the base A in line with the advancing barbed cab1e-wires. It has a concave mouth to direct the projecting barbs into a longitudinal slot therein, through which the barbs can slide, but in which slot the barbs and complete cable will be prevented from revolving.

G is a tubular shaft mounted at its front end upon the base A-in line with the barbgrasping device G. It. also has a concave month and a cruciform longitudinal passage way for the barbed cable, that will grasp barbs on the cable and twist it as the shaft is re- IIO volved, and make one or more twists in the cable at the point intervening between the parts G and G every time a barb is completed and the parallel barbed wires advanced a distance corresponding with the uniform spaces between the barbs.

H is a driver chain-wheel fixed to the rotating shaft and twister G".

H is a driver chain-wheel fixed to the rear end of the driving-shaft O.

I is a drive-chain placed upon the chainwheels,to transmit power and motion from the shaft 0 to the shaft G to operate the twister slowly and continuously.

To securethe intermittent motions required to wrap the barb-pieces around the two parallel wires, I employ a stop-motion gear,which consists in a wheel having a series of cogs upon its periphery at distances apart and depressions at the end of each series, as clearly shown in Fig. 9, and one or more pairs of long cogs in a pinion, to slide on the smooth portion of the periphery and retain the pinion stationary until one of the long cogs enters one of the depressions, to allow the pinion to revolve until the ends of a pair of the long cogs again both engage a smooth section of the periphery of the continuous]y-revolving mutilated gear.

No. 6 is a mutilated-gear wheel having four distinct series of cogs and depressions, t, on each side of each series, as required to impart'four distinct motions to the pinion J, that has two pairs of long cogs, k In, at each revolution of the wheel No. 6, fixed to the front end of the shaft (3.

No. 7 is a stop-motion gear-wheel fixed to the shaft 0, to operate my barb-bender and barb-tucker mechanisms. It has only one series of teeth to engage a pinion, L, that has only one pair of long cogs, and is fixed to a.

shaft, L suspended in hangers from the under side of the base A in such a position relative to the wheel No. 7 and the bar e that motion will be imparted to the shaft L to rotate the disk f, and thereby operate the barbbender e at each revolution of the shaft 0.

L is a pinion having a pair of long cogs fixed to a suspended shaft, L", in such a position relative to the wheel No. 7 and the lever g that a crank,- m, fixed to the shaft L, will engage and vibrate that lever at every revolution of the shaft 0, as required to actuate the tucker f at regular intervals.

No. S is a stop-motion gear-wheel fixed to the shaft 0, to operate mechanism for advancing the barb-wire to the cutting mechanism at regular intervals.

at n are feed-wheels. (Shown in Fig. 5.)

' 0 is a shaft suspended in hangers from the base A, to operate the feed-wheels n by means of bevel-gear wheels (shown in dotted lines in Fig. 1 and in full in Fig. 8) in a common way.

A pinion, 0, having one pair of long cogs on the end of the shaft 0, engages the wheel No.

:- 8, to be actuated thereby, as required to transmit intermittent motions to the feed-wheels at regular intervals.

No. 9 is a driver-pulley fixed to the shaft 0, to receive a belt connected with a motor adapted to operate my machine.
