IMPROVEMENT IN WIR E-B AR BING MACHINES.

Specification forming part of Letters Patent No. 188,436, dated March13, 1877; application filed October 25, 187 6.

To all whom it may concern:

Be it known that I, DANIEL (J. STOVER, of Freeport, Stephenson county, State of .Illinois, have invented new and useful Improvements in Machines for Put-ting Barbs on Wire, of which the following is a full description, reference being had to the accompanying drawings, in which-- Figure 1 is a side'elevation; Fig. 2, a plan view; Fig. 3, a rear view with the frame omitted; Fig. 4, a longitudinal vertical section; Fig. 5, a front view with the frame and driving-wheels omitted; Fig. 6, details of the side hammers or plates.

The object of this invention is to apply barbs to all kinds of wire used in making fences, firmly and expeditiously; and its nature consists in feeding the main or fence wireinto the machine at intervals; in feeding in a crosswire, from which the barbs are formed at the same intervals; in forcing the barbs tightly into position by a'series of hammer or slides; and in the several devices and combination of devices for operating the parts hereinafter more fully described and claimed as new.-

In the drawings, vA represents the main frame; B O, the head-block or frame; .D, the discharge opening; E, the platform; F, the guides; G, the slide; H, the tube through which the main wire passes; I, the pivoted block to. Which the tube H is attached; J, the supports for the block I; K, the tube-guide; L, the lever for operating the slide G M, the bar or pitman for operating the lever L; N, the bearing-block; O P Q, the gear-wheels operating the feed of the crosswire from which the barbs are formed; R S, the guide-wheels for the barb-wire; T, the spur-wheel; T, the pin-wheel; U V W X, the gear-wheels; Y, the balance-wheel; Z, the

"main shaft; 0. a a b 12 b the guide-plate; c

d, the plates or hammers moving vertically; c f, the plates or hammers moving laterally; g h i j, the cam-wheels or eccentrics for operating the hammer-plates; k, the eccentric-for operating the lever L; l, the fixed plate against which the main wire is driven; m, the springs for returning the hammer-plates; n, the guide'through which the barb-wire is fed; 0, the outward projection on the plate d; p,

the spring for returning the lever L; g, the

support for the bar M; r, the clamp on the I rear end of the tube H; s, the opening in the pivoted block I; t, the pin for rocking the tube 11; "a c, the cutter; w, the shoulders on the plates 6 f for setting the barb; w, the holes in the plates 1 0 for holdingthe main wire'when the tube H returns; 3 the groove in the face of d, into which the main wire and barb are forced so as to form the barb vshaped.

The. frame-work A B .O and platform E may be made of iron, or partly of iron and partly of wood. The head'B (3 may be-made of iron, and in any suitable form for'supporting the parts which attach the barb. It is provided with a central opening, D,-,large enough to pass the wire after the barbs are applied. Its rear face is furnished with guideplates 0. a a b b b for holding the sliding parts in position.

The sliding plates or hammers c d are each provided with a groove across their workingfaces, made sufficiently deep to take in near- 1y or quite one-half of the main wire. The side plates orhammers cf are cut away at to, as shown, so as to pass over the main wire .and' bend the barb, and bring the shoulder up to themain wire, so as to firmly set the barbs in position. These platesc d cf are operated by the cams or eccentrics g h z'j, which cams are operated from the gear-wheel X on the main shaft Z, through the wheels W V U,, as shown.

The platform E is provided with guideways F, between which the plate G is operated.

This plate carries the tube H, through which the main wire passes, which tube is pivoted by the block I to the supports J, so that the front end of the tube may rise and fall with- I in the limits of the opening K. The tube H is provided at its rear end with the eccentric or clamp T, which operates automatically, and

holds the wire for the purpose of feeding.- j

This wire passes under the guide-plate 'b, which may be sharpened at its lowerendat e, or a shear-blade may be attached thereto, so that when the hammer-plate d rises, the

wire will be severed at u with an angular cut, so as to give the barbs sharp points.

This barb-wire is fed up at suitable intervals by means of the gear-wheels O P Q, which are operated by the spur or spoke wheel T and the pin-wheel T, which advances the wheel T one step at each revolution or complete operation of the devices for fastening hammers efarezgrooved on the top, soias to catch the ends of the barbs and carry them over to the opposite sides. r y

The springs in 17, in the form shown, are

simply bent plates, used for returning the parts into position to be operated upon by the eccentrics or .cams. This form will be found convenient; but, in practice, they may he made in any other suitable form which will accomplish the desired resultof returning the parts. 1

r In operation the main wire is passed through the tube H, with its end projecting, out far enough to attach the first barb. The cross or barb wire is supported upon any suitable spool, which maybe detached from the ma chine or attached thereto, as desired. Its end is passed between the grooved wheels It S, and through the loop a. The machine is now ready for starting. 1 i

In the first movement the tube H is advanced by the eccentric is pressing against the end of the rod M, which moves the lever L, causing the plate G, with the tube H and appliances, to advance, so that the endof the tube comes up over the hammer-plate. d, and under the guidea. When this tube H has advanced about two-thirds of this distance,

the pinoriarm on the wheel T willcome in contact with one of the spursor arms of the.

wheel T, causing it to advance and, through the gear-wheels O P Q and grooved wheels 1% S, force thecrossor barb wire forward un-. der the main wire the desired length forthe barb. In this position, with the end of the tube H over the barb-wire, as described, the

hammer-plate d rises bymeans of the co centric it coming in contact with the lower end thereof, and the cross orbarb wire is severed at a by means of the cutter o. The main wire, with the barb, is then carried up by the continued rising of the plate (1, until the endofthe tube H strikes the lower end of the plate a, when the barb and wire areforced into the groove 3 on the face of the hammer-plate d, which causes the. barb to assume a V shape. Thenthe tube H recedes,

the main wire being held firmly between the end of th'e'plate l and the part 0 of the hammer d in the holem. Then the sidelhamm'ers 6 fare forced forward, simultaneouslymby means of the cams ij coming incontact with the outer ends of the hammer-plates, and the ends of the barb being above the points of the ha'mmersor plates e f, thesepoints will catch theends of the barbs and cross them over to opposite sides, so as to encircle the main wire, ,and the shoulders to of these plates will strike against.this encircling portion of the barb, and bring it in close contact with the main wire, and force the barb ends at nearly right angles therewith. Then these hammer-plates e f are released from their contact with the cams i j, and will be returned to their first position by means of the spring m. The hammer orwplatec will now descend by meansot the eamgcoming in contact with the upper-end thereof, and, striking the barb ontop, will complete the fastening,and set the barb firmly in position.

so that it will not move. Then the plates c at will be returned to theirfirstpositionsth-rough the springs m, leaving the main wire and 'barb free to be passed through the opening D by the forward movement of the tube H, which 'takesplace as soon. as the hammer-plates c d are returned. The hammers or plates e fare :so formed at their .points ortinner ends that they will pass each-otheryso as to cross the barb-wire, and :permit the shoulders 20 to come in eontactwith theencirclingportion thereof. These hammers e f areyadvanced and returnedsimultaneously, so thatwhen advanced they willact upon both points of the barbat the same time,and thus .insureuthe proper coiling of the barb-wire around the main wire.- The hammer chatter it is raised, a will remain in that position, and serve the purpose of an anvil forthe completion of the fastening by the hammerc. Both .of the hammers ad will return to position simulso that barbs will be applied atregular inter,

vals. By extending theguidect inward, as shown, the upward movement of the tube H islimited, so as to prevent :anybending or kinking of the main. wire while thebarbs are being fastened, and also to furnish amean s for forcing the barb into thegroove you :the

hammer clito form 'the vshape; but some other form ofstop might be used for this purpose.

It will be seen that by themethod herein described the turn or coil of thebarbi around the main wire is firmly held against it,-so that when the blow or pressure from. the hammer or plate a is given, the eneirclingportion retainswits forn1,.without beingmade oval or drivenawayat the sides, so that the coil is in the sliding plate G and lever L, for carrying the main wire forward, substantially as speci- 2.
