BARB-WIRE MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,885, dated March 11, 1884.

Application filed March 12, 1883. (No model.)

To all whom it may concern Be it known that I, GODFREY H. LASAR, of St. Louis, Missouri, have made a new and use 'ful Improvement in Barbed-XV ire Machines,

of which the following is a full, clear, and eX act description, reference being had to the annexed drawings, making part of this specification, in which Figure 1 is a side elevation of the improved machine; Fig. 2, a plan; Fig.3, a plan upon an enlarged scale of the barb-forming mechanism; Fig. l, a vertical transverse section upon the line 4 4 of Fig. 2, the view being upon a larger scale than that of Fig. 2; Fig. 5, a rear elevation of the knife-standard;Fig. 6, a plan of the knife-standard, the cap being removed; Fig. 7, a front elevation of the knifestandard and the movable knife and slide; Fig. 8, a horizontal section taken on the line 8 8 of Fig. 7; Fig. 9, a section, looking rearward, on the line 9 10 of Figs. 2, 11; Fig. 10, a similar section, the parts being in a different position; Fig. 11, a section on the line 11 11 of Fig. 9; Fig. 12, a view'showing the upper portion of the parts shown in Figs. 9, 10, the lock being engaged; Fig. 13, an end view of one of the strand-wire tubes; Fig. 14, a section on the line let 14 of Fig. 15; Fig. 15, a longitudinal section taken through a strand-wire tube; Fig. 16, a side elevation of the delivery end of a strand-wire tube; Fig. 17, 'a view in perspective of the construction shown in Fig. 16; Fig. 18, a transverse section taken on the line 18 18 of Fig. 2; Fig. 19, a longitudinal section taken on the line 19 19 of Fig. 18; Fig. 20, a longitudinal section on the line 20 20 of Fig. 1; Fig. 21, a longitudinal section on the line 21 21 of Fig. 2; Fig. 22, a longitudinal section on the line 22 22 of Fig. 1; Figs. 23 to 27, diagrams illustrating the forming of the barbs, Fig. 23 showing the barb-wire fed between the strand-wires, Fig. 2% showing one (the lefthand one, as seen) of the straudwire tubes turned half a revolution around, as indicated by the arrow, and the barb-wire bent accordingly, Fig. 25 showing the left hand tube turned around a three-quarters and the righthand tube a quarter revolution, and the barbwire bent accordingly, Fig. 26 showing the left hand turned a full and the right-hand tube a half revolution, and Fig. 27 showing the left-hand tube turned a little more than, and the righthand tubealso turned a little more than, a full revolution, and barb-wire bent accordingly; Fig. 28, a section on the line 8 8 of Fig. 7, and also showing the strand-wire tubes and wires in the position corresponding to the diagram of Fig. 24; Fig. 29, a view similar to that of Fig. 28, the tubes and wires being in the position corresponding to the diagram of Fig. 26; and Fig. 30, a view in perspective, showing the movable knifeslide.

The same letters of reference denote the same parts.

In this machine the strand-wires are respectively fed through two tubes, which are inclined to each other, and have their delivery ends in proximity to each other. The barb-wire is fed crosswise between the strand-wires just in rear of the tubes. The tubes rotate and cause the barb-wire to be intertwined upon the strandwires, the tubes being supplied with projections, which encounter and carry the barb wire around the strand-wires. The tube on the opposite side from the barb-wire-severing apparatus first acts to partially attach the barbwire'upon the strand-wire in that tube. The severing apparatus then acts to out off a barb length of wire, and .the attachment of such barb length to the strand-wires is completed. The barbs are attached to the strand-wires at suitable intervals, and the twist is put intothe cable and the barbed wire drawn rearwardly in the machine and wound upon a spool journaled in a revolving frame.

A A represent the strand-wire tubes.

B B, Figs. 23 to 27, represent the strand wires, which are fed through the tubes A A, respectively, and in the direction indicated by the arrows a a, Fig. The tube A is provided with the gear a, which engages with the gear 0, and the tube A is similarly furnished with a gear, a which engages with the gear 0. Both tubes are adapted to be rotated in the bearings Ma. The axis of gears O 0 turn about the bearing D, Figs. 1, 8, 11. The gear 0 is fastened to or made "part of the gear 0, so that when the last-named gear is rotated the gear 0 rotates with it. The gear 0, by means of the sleeve 0 is connected with the gear a, so that when the last-named gear is rotated the gear 0 rotates with it. The gears 00, as shown in Fig. 11 more distinctly, are sustained upon the bearing D. The object of the mechanism last above described is to provide for rotating the tubes A'A independently of each other and at certain times. To this end the gears are driven, respectively, by the gears E E. These gears E E are, in efl'eet, a double gear, attached to and rotating as one piece with the shaft F. In both of the gears E E a portion of the teeth is omitted, as shown more distinctly in Figs. 9, 10that is, the teeth 0 extend halfway around the gears, and around the other hall, 0, the teeth are omitted. The gears E E are relatively arranged, so that the teeth 0 of one of the gears lap upon the part c of the other gear. As shown, the gears E E are proportioned to the gears c c as two to one, and the teeth clap half-way upon the part '0'. Each gear 0 and 0, therefore, is in motion just half the time, making a revolution and then stopping; but the two gears are simulta neously at rest only during one-fourth of a revolution of the gears E E.

The gears E and E can be relatively adjusted by means of the slots c" and screws 0, so as to make the teeth 0 to lap upon the part c, as desired. The aim, as stated, is to cause the tubes to be rotated during certain fixed intervals, and then to be at rest during certain fixed intervals. To efl'ect this with more certainty each-gear E and E is provided with a lock,G and G, respectively,which locks are attached to slides r g, respectively, that work upward and downward in a guide, g'flagainst the sides respectively of the double gear E E, substantially as shown in Figs. 9, 10, 11, 12. The locks, each of them, are provided with hooks which, as the gears E E are rotated, are caught by the studs y, one on each side of the double gear,) causing the locks to be drawn downward and to be disengaged from the openings or notches y in the circular flanges g", with which the gears c c are respectively provided. \Vhen the locks are thus disengaged, the gears c c are free to be o rotated by the gear E E, and during the "rototion the locks bear upward against the .gagement with the hooks g.

flanges 9. As soon as the openings come around again, springs act to lift and thrust the locks into the openings, where they remain until the studs g are brought into en- To insure the entrance of the looks into the openings f the flanges are shaped so as to bring the end a little within the opposing end of the flange, and as the springs keep the lock against the flange the lock cannot pass the opening. The flanges are arranged upon the gears c 0, so as to bring the openings opposite the looks as the teeth 0 become disengaged from the gears c 0, respectively.

The tubes A A are provided with extensions a a, the office of which is to efi'ect the bending of the barb-wire around the strandwires. As these extensions are liable to wear, it is desirable to make them detachable from the main part of the tubes, and this is preferably carried out as follows: The extension is made part of a tube, a, which is attached to the rear end of the main tube a. The main tube is slotted at a c, Figs. 14, 15. A nut, a is screwed onto the slotted portion, causing it to be contracted upon the tube a". The lastnamed part is provided with studs a" a.,which project into the slots a c and prevent the tube a from being turned around in the tube (1. The strand-wires pass from the tubes A A into and through the central opening, 7:, in the flier H. The flier is held and adapted to be rotated in the bearings h h. It supports and carries with it in its rotation the feed device I, the spool J, and the guide K. The wires having the barbs attached pass first around the sprocket-wheel i of the feed de vice, and thence partially around the small sprocket-wheel i. From the last-named wheel the barbed wire passes over the guide-wheel K, and then to the spool J, onto which it is wound. Motion is imparted to the flier and to the machine by belting onto the pulley L, Figs. 1, 2, which is attached to an extension of the rear flier-journal. (Xot shown.)

)Lis a fixed gear,with which engages a pinion, X, Figs. 1, 2, 22, that is uponashaft, a. This last-named shaftis journaled at a in the flier, and is provided also with a worm, a, that engages with the gear a The gear a? is attached to the shaft n, which is also journaled in the flier at 21", and is provided with a pulley, a. A belt connects the pulleys n and nlthe last-named pulley being upon the spoolshaftj. By this means the rotary motion of the flier is communicated to the spool, causing the spool to rotate and the wire to be wound upon it. At the forward end, it", of the flier, encircling the opening 71, and fixed to the frame 0 of the machine, is a stationary gear, 1 with which. engages apinion, 1), Figs. 1, 2, 19, that is upon the shaft P. This shaft 12 is journaled at p" in the flier, and is provided with a worm, p, which worm engages with the gear 12, Fig. 2, that is attached to the shaft of the sprocket-wheel 1'. 3y this means the rotary motion of the flier is transmitted to the shaft and the feed device Iset in operation, causing the wire to be drawn steadily and positively through the flier-opening 71. The guide K is upon a right-and-left hand threaded shaft, 7;, for the purpose of properly delivering the wire to the spool J, the guide moving to the right and left upon the shaft 7; in the usual manneras the wireis wound upon the spool. Upon the forward side of the standard 0 the flier is provided with the gear Q. This gear engages with the gear Q upon the shaft F, Figs. 1, 2, 19, 18, and serves to transmit the motion of the flier to the shaft F, and ultimately to all the mechanism employed in delivering the strand-wires and forming the barbs.

R, Figs. at, 1, represents a cam on the shaft F. It operatesin connection with the roller r lCO upon the pitman r. This pitman is slotted at r to passaround the shaft F, and at oneend is connected by means of the spring r to a fixed part, 1*, of the machine, and at its for- .arm r is attached loosely to theshaft r upon which is fastened the ratchet r. The cam R, turning with the shaft F, causes the'arm r to vibrate, and through the pawl r to turn the ratchet r and shaft r This last-named shaft turns in the bearing 0', and is provided with the grooved wheel 1* and the gear 1 The wheel 1"" works in connection with the grooved wheel r upon a shaftabove and parallel with the shaft r and having the gear r, which is in engagement with the gear 1*. The wheels serve to feed the barb-wire through the barbwire-severing device and in rear of the tubes A A, as indicated by the arrow'm in Fig. 2.

T represents the device for cuttin gthe barbwire. A cam, t, Fig. 7, upon the shaft F op crates-t0 depress the free end t of the lever F. This lever is jointed to a pendant, 25 that is attached to the slide S, and the movable knifeslide 16* is jointed to thelever t at t, and when the .lever 25 .is depressed, as described, the movable knife 29, that is attached to the slide,

is drawn down past the fixed knife t", Fig. 30,

severing a barb length of wire, Figs. 23, 27. The movement of the knife t is suitably timed to cut the wire in the proper lengths. The stationary knife 15" is held in the slide-standard 1 The knife-slide and standard are cutaway at t t", to provide for the passage of the barbwire to the knife and to the strand-wires. The movement of the barb-wire, as it is, by means of the tubes A A, attached to the strandwires, is illustrated in Figs. 23 to 27, and also in Figs. 28, 29. The tube A, by means of the projection a, first acts and initiates the bending and attachment of the barb-wire. The knife then severs the barb-wire, and then the two tubes A A jointly act to complete the barb.

The slide S is movable longitudinally upon the bed-plate S of the machine, to enable the barbs to be formed without arresting the'movements of the wires. All of the parts above the slide move with it, as well as those parts beneath the slide, saving the cam f, Fig. 1,

which is fast upon the shaft F, and is grooved to receive the stud f, which is attached to the slide. The rotation of the shaft F, therefore, causes the slide and all the parts resting upon the slide to reciprocate longitudinally upon the bed-plate S. The latter is providedwith a hanger, s, which engages in a groove, e; in the hub c of the gear E E, causing the lastnamed gear to slide upon the shaft F. A feather (not shown) causes the shaft F and gear E E to rotate together. The slide S is also furnished in a hanger, s", which engages in a groove between the cams t B. These last-named parts are, in practice, united, and move as one piece upon the shaft F, and the groove spoken of is the space between the two cams.

The device shown atVV, Fig. 21, is for bold ing the removable shaft 3' in place in the flier H. When it is desired to remove the spool J,

the slide WVis drawn longitudinallyupon flier until the opening 10 is. opposite the shaft j, whereupon the shaft, by means of the handle 3', is withdrawn through the opening 10 from the flier.
