WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 273,838, dated Iifiarch 13, 1883.

Application filed January 8, i883.

1'0 all whom it may concern Be it known that we, HUGH B. HEDGE and THERON A. NOBLE, of Des llloines, in the county of Folk and State of Iowa, have in vented an Improved Wire-Barbing Machine,

of which the following is a specification.

The object of our invention is to provide a means for bending barb-pieces around a fencewire by impartingreciprocating rectilinear motions to the barb-headers in place of rotary motion, as heretofore, and to actuate the reciprocating barb -benders and wire moving mechanism by cams on one and the same shaft, and to apply two barbs on the wire at regular distances apart at each revolution of the shaft, to thereby speed the work without increasing the speed of the machine, and to save time and power in producing any given quantity of barbed wire.

It consists, first, in forming and combining a barb-holding device with a stationary head and a revolving grooved disk or cam-wheel; second, in combining reciprocating barb-benders with the stationary head and grooved camwheel; third, in combining a. wire moving and spacing device with the barb-holding and barbbending mechanisms; fourth, in combining an automatic wire-holding device with the barbbending and wire moving mechanisms to hold the wire stationary at regular intervals while the barbs are being fixed thereon, all as hereinafter fully set forth.

Figure 1 of our accompanying drawings is a side view of our machine; Fig. 2, a top -view;

5 Fig. 3, a longitudinal section; Fig. 4, an end view; Fig. 5, an enlarged sectional view of the barb-holding device. Fig. 6 is a face view of the grooved cam-wheel and side view of the reciprocating barb-holding and barb forming o or bending devices in position as required to allow the legs of a staple-shaped barb-piece astride of the fence-wire to pass downward between them. Fig. 7 is a horizontal section of the stationary head and cam-wheel, showing 5 the barb-benders in the same position relative to the cam-wheel and barb-piece on the wire as shown in Fig. 6. Fig. 8 is a vertical section of the head and cam-wheel, taken at right angles relative to Fig. 6, to show the barb-hold o ing device in position as required when the (No model.)

wire is moving. Fig. 9 is a. face view of the cam-wheel, showing the barb-headers in position after bending the staple-legs of the barbpiece in opposite directions relative to the fence-wire as required to produce a complete fixed two-pointed barb. Fig. 10 is a horizontal section of the combined head and cam-wheel and a top view of the complete barb and barbbenders in the same position as shown in Fig. 9. Fig. 11 is a vertical section of the combined head and cam-wheel, showing the barbholding device in position as required when the barb-benders are advanced in opposite directions to bend the legs of the barb piece upon the fence-wire. Jointly considered, these figures clearly illustrate the construction and operation of our complete invention.

A represents a metal plate and base, upon which our stationary head Bis fixed by means of screw-bolts. It is supported upon suitable legs and a frame.

0 is a tubular shaft, supported above the base A by bearings G.

O is a disk or wheel having cam-grooves in its front face, fixed to the end of the tubular shaft to revolve against the face of the fixed head B. An opening in the base'plate A allows the cam-wheel C to extend downward be low the fixed head B.

No. l is a gear-wheel fixed to the central portion of the tubular shaft. An opening in the base-plate A admits the wheel to extend below the plate to engage a second gear-wheel. No. 2 is a gear-wheel of smaller diameter, fixed to adriving-shaft, O ,that is mounted in bearings fixed to the frame or legs that support the base A. No. 3 is a driver-pulley fixed to the shaft 0 and No. A is a loose belt-pulley on the same shaft. No. 5 is a driver-pulley fixed to the opposite end of the shaft CF to transmit power and motion to wire-twisting and cable-forming mechanism. Nos. 6, 7, and S are sprocket wheels, mounted in a 'l'rame,1) D, (fixed to the rear end of the base-plate A,) by means of shafts Nos. 9, 10, and 11. The wheels Nos. 6 and 7 are connected by gearwvheels.

D is a collar fixed on the tubular shaft 0. It has a serpentine cam-groove, a, in itsperiphery.

D is a sleeve fitted around the grooved cole e erases lar D and it has arms a, pivoted at its opposite sides to operate pawls a. that engage the ratchet-Wheels a, that are fixed to the shaft No. 9.

a" are arms pivoted to the shaft No. 9 at their lower endsand to the arms a and the pawls a, at their upper ends. The pivots or screw-bolts b, that connect the arms a with the slide D extend into the serpentine groove a of the collar D and by means thereof the formed in therear face of the fixed head B, as

clearly shown in Fig. 5.

f is a stud that extends laterally from the upper portion of the straight barb-holder f into the cam-groove d d. At every half-revolution of the cam-wheel (J the barb-holder f is pressed down toward the fence-wiregand upon the barb-piece g by means of the inward bends d in the cam-groove d and the stud f, that traverses the camgroove.

g" (clearly shown in Fig. 5) is an auxiliary barb-holder, that has a notch in its lower end to fit over the wire g, and to prevent the barbpiece 9 from sliding rearward on the wire. It has a stud, g', that extends into a continuous groove,-h, formed in the center portion of the face of the wheel 0 It are short outward bends-in the groove it, that elevate the auxiliary holder g at every half-revolution of the cam-wheel to allow a fixed barb to pass rearward as the wire 9 is moved by the spacing mechanism.

h is a block fixed to the lower end and out-l arejointly beveled to form an incline of about.

forty-five (45) degrees. An opening through the fixed head B allows this block vertical 1120-;

tion.

h is a barb-separator. nal slot or bridle, through which ascrew-stud is passed into the inclined bottom face of the block it to connect the separator with the harb-holderf. The lower end of the separator is curved and bifurcated in such a manner that when it moves downward with the barb-holder it will straddle the fence-wire g, and separate one of the staple-form barb-pieces g from a series hanging upon the wire by an independent sliding motion on the incline of the block it, caused by its contact with the fence-wire and the downward motion of the barb-holderf.

h is a spring fixed to the head B at its upper end, and to the separator h at its free lower end. As the barb-holder f moves upward the force of the spring will push the sepa- It has a longitudirator downward on its inclined bearing, and rearward relative to the machine, and wire 9, that extends through the tubular shaft 0 to retain the loose barb-pieces while the wire is advanced.

it, shown in Figs. 6, 7, 9, and 10, are two reciprocating barb-benders that move in corresponding horizontal grooves,'i, formed in the inside face of the fixed head 13. Each has a stud, 70, that projects into a continuous camgroove, m, formed in the face of the wheel 0 m are two equidistant inward bends in the grooves m, by means of which the barb-benders i, having studs 7c. are simultaneously moved toward each other, and against the legs of the barb-pieces g, as required, to bend the staplelegs in opposite directions, and upon the fencewire 9 at the same time that the barb-holder f presses the barb-piece upon the top of the wire ateach half-revolution ofthecam-wheel 0 No. 12 is a ratchet-wheel fixed to the shaft No. 9.

n is a pawl pivoted to the frame D. 0 is are on top of the base A. The rear end of the rod 0 is pivoted to the top end of the pawl 12.

o is a lateral projection and shoulder at the front end of the rod, that is engaged at every half-revolution of the wheel by cams 1', that project from the rear face of the wheel (J at equal distances apart.

0 is a collar fixed on the rode.

o is aspring placed between that collar and one of the bearings 1) in such a manner that the spring will, in its normal position, press the rod 0 forward to retain the pawl n in one of the notches 0f the wheel No. 12 as required to hold the fence-wire gstationary whilethe barb-benders t are bending the barbpiece around the wire; and when the barbforrners have completed their inward motions and work, one of the cams r on the rear face of the wheel C) engages the shoulder 0., and thereby compresses the spring 0 and moves the rod rearward to release the pawl 12 from the wheel N o. 12 as required to allow the wire 9 to move a certain distance, and to fix barbs upon the wire at uniform distances apart.

s is a bracket fixed to the front end and center of the base-plate A.

s is a bearing, upon which the wire 9 is advanced into the tubular shaft 0.

s" is .anadjustable pressing device, hinged to'the bearing s in such a manner that the complete device will guide and straighten the wire as it is drawn through by the operation of the sprocket-wheels Nos. 6 7 8 and a reel Fig. 5, by hand, or by means of suitable automatic machinery, combined and operated in concert with the barb-holding, barb-fastening, and \vireemoving mechanisms.
