SPECIFICATION forming part of Letters Patent No. 584,783, dated June 1 1 7- Application filed February 13, 1897. Serial No. (323,247. (No model.)

To (ti/Z whom, it may concern.-

Be it known that we, XVILLIAM O. BATEs and WILLIAM J. HUTcHINs, citizens of the United States of America, residing at J oliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Electric lVire-Barbing Machines, of which the following is a specification, reference being had therein to the accompanying drawings and the letters of reference thereon, forming a part of this specification, in which- Figure 1 is a plan of the machine; Fig. 2 a side elevation of same; Fig. 3, a central vertical longitudinal sectional elevation of the same, omitting the spooling mechanism; Fig. 4, a cross-sectional elevation 011 line 1 1 of Figs. 1 and 2; Fig. 5, a detailed View of one spooling-shaft of the machine; Fig. 6, a detailed side view of a pair of the machineelectrodes represented in service; Fig. 7, a detailed perspective of one pair of barb-prod cutters of the machine, represented in service; and Fig. 8, a perspective view of a section of barbed fencing, the same being a pro duct of the machine.

This invention relates to certain improvements in wire-barbing machines, and relates to a machine wherein barbs are electrically welded to a strand wire or wires; and it consists of means for intermittently conveying a plurality of strand-wires across the machine, means for placing barbing-wire across the strand-wires, means for actuating electrodes for grasping the strand and barbing wires during a period of time sufficient to make a weld, of means for cutting the barb-prods and means for spooling the barbed wire, which improvements are set forth and explained in the following specification, and pointed out in the claims.

The object of this invention is to produce a machine for electrically welding barbs to a fence strand wire or wires.

Referring to the drawings, A is the machine-bed, mounted on standards, as shown; A, a pair of angle-iron bars fixed at one end to bed A, bent down at their outer end to form floor feet, and arranged a distance apart, as shown.

B are uprights fixed upon bed A, one at either side of the bed, and are made with guideways between which a vertieally-slidin head L is arranged. 3 is a cross-shaft boxed in the upper part of uprights B and has fixed upon it an eccentric C, which, through the agency of a strap 0, operates head L. A sprocket-wheel M, about which a chain belt is passed, drives the shaft B, on which shaft a pulley P, through the agency of a belt J, drives the wire-spooling mechanism; and a disk D on this shaft 13, through the agency of a crank-pin and connected rod D, operates the wire-feeding mechanism intermittently and by means of a peripheral cam-lug D actuates the barb-prod-cuttingmechanism.

S is a cross rock-shaftboxed at its end portions in. uprights B, and has fixed on its portion between said uprights a cutter-head S, having adjustable barb-prod cutters (1 set therein, and further has fixed on one end at the outer side of upright B an arm N, having a friction-roller N housed in its eXtending end portion, arranged to impinge upon the periphery of disk D and be operated to actuate the said cutters by said cam-lug D and is held yieldingly against said disk by means of a spring g, (see dotted lines in Fig. 3,) which returns the arm and cutters to their normal position after each actuation.

II is a cross-frame fixed upon bed A between uprights B and supports adjustable station upright cutters d in such position that cutters (Z shear therewith to cut the barbprods.

F is a cross-frame fixed upon bed A and supports electrodes 0, insulated therefrom in a fixed position and between the cutting end portions of cutters d, and above are arranged fellow-electrodes e, insulated to stems adjustably set in the sliding head L in such manner as to be operated by'said head to contact wire resting upon the lower electrodes 0.

II are housings fixed upon bed A and support cross-shafts R R, upon which are fixed pairs of wire-feeding rolls R R, which are geared together-in pairs, as shown, and made adjustable so as to be set to firmly pinch the wire feeding between them. Fixed on one end of shaft R is a ratchet-wheel E, and sleeved on said shaft at the side of said ratchet is an arm D, having a pawl E, arranged to engage the ratchet-teeth and adjustably connected at its slotted end portion with rod D. Fixed to housings II II are wire-guides a, arranged to guide wire IV from rolls R It to the upper plane of electrode 6, so the wire will be fed across said electrodes.

K K are other housings for barbing-wire feed-rolls R R, stationed at the side of bed A in such position that wire 'W will be fed through a guide X into the machine across wires IV immediately above electrodes e and across cutters d. The lower shafts of rolls It and R are geared together, as shown at G G, so they will operate jointly, the said gears being proportioned so as to turn rolls R sufiiciently to feed the required length of wire from which to properly cut the barbs. If so desired, a second housing, pair of rolls, and gears like unto said barbing-wire feed-roll mechanism may be stationed at the opposite side of the machine and one-half of the required barbing wire fed in at each side.

Boxed in bearings fixed to one an gle-bar A are right and left hand screw-threaded hollow screws Z. Boxed in opposite similarbearings fixed to the opposite bar A are miter-gears I, and Z are shafts placed through screws Z on feathers brought to span the space between bars A A and entered at their end portion into gears I, where they are removably held by means of cross-pins 1 (see Fig. 5,) and placed upon said shafts are spools S, placed connected with screws Z, so as to turn therewith by being coupled with heads f of said screws. (See Fig. 5.) Bracketed to one side of bar A, supporting-gears I, is a shaft 3', having fixed thereon gears I, arranged in mesh with gears I, so as to drive said shafts and screws Z Z jointly, and the hub of the lirst of said train of gears Ihas fixed thereon apulley P, about which the belt J passes to drive said train, which belt is made so as to slip on its pulleys at times when said train cannot turn, and as a means of holding said belt at a proper tension an idler-pulley J, which is studded to the upper end of a lever J, fulcrumed to the side of bed A, is held thereagainst, which lever is held adjusted by means of a cord h, arranged connecting its lower end with a hand-winding spool U, studded to the side of bed A and provided with a ratchet-wheel t, which is engaged by a detent-pawl t to hold the proper adjustment.

Placed in conjunction with each screw Z is a forked switch V of the usual type (see Fig. 5) for the purpose of causing said screws and the spools connected therewith to assume a side alternating movement when rotated, so as to distribute wire evenly upon the spools. O is'a cross-rod supported by suitable uprights and has sleeved thereon a plurality of butterfly-wheels 0, and sleeved on other upright cross-reds 3 are other butterfly-wheels 2 over which wire is conducted to the several spools, as shown.

In operation the wires W to be barbed are fasteners and utilized fed in between rolls It It, through guides a, over electrodes 6, over butterflies o and 1 to their respective spools The barbing-wire is fed in between rolls R 1', through guide X, across wires W and cutters (Z, and over electrodes 6; hence under electrodes 6 and cutters d. The electrodes 0 are electrically connected by means of conductors \V, and electrodes c are similarly connected by conductors \V, which comluctors are of the same electric circuit, and when the wires have been placed as stated the electrodes 6 move down upon the'barbing-wi re IV, pressing it lirmly upon wires IV on electrodes c, which action makes the electric circuit through said wires, and by reason of the resistance thereat the wires are fused and welded together, and such duration of contact is only sullicient to attain the result stated, which duration or time of contact is controlled by the speed of the machine. At the conclusion of each such. weld the cutters d are actuated and cut the barbing-wire "W obliquely between the wires IV, and thus form the barbs, which, by reason of the oblique cuts, are pointed and form prods. At each feed of the wires IV they are taken up by the spools S, which are driven with sufficient friction to aid in advancing said wires.

If desired, the cutters (Z and (1 may be shaped and set to sever the wire \Vsquarely, or nearly so, so that instead of forming prods on said attached parts they may be used as such by bending them to secure stay-wires to a fence, or the barbs, made as shown, maybe likewise bent and serve as fasteners. Alsollat metal strips or other shaped metal parts may be placed J across the strand-wires \V and electrically i105 welded thereto instead of the wires \V, if so; desired.

Having thus described our invention, what we claim as new and useful, and desire to secure by Letters Patent, is as follows:
