Like characters of reference denote corresponding parts throughout the figures.

The frame The frame of the machine includes a preferably vertically disposed stationary cylindrical member 1 having an opening 2 in its wall which is of suitable height and width to accommodate the placing in the frame and the removal therefrom of the spools or reels on which the completed barbed wire is wound and, also, to permit an operator to have access to the operating parts within this cylinder. The opening 2 is adapted to be closed by a sliding door 3 which is movable circumferentially of the cylinder, see Figs. 2, 3, 4 and 19, and said door is provided with a handhold 4 to permit an operator or an attendant to open and close said door. The cylinder rests on and is secured to a base frame 5 which is provided interiorly and axially with an oil shroud 5 and with a ball bearing 6 in connection with which is journaled certain operative parts to be described.

Resting on and secured to the upper end of the cylinder is a head frame 7 which said frame, as will be seen in Figs. 1, 2 and 8, projects from and is offset to the body of the cylinder and such extension designated 8. From the extension 8 of the head frame projects a bracket 9, see Fig. 1, and the head frame proper is provided with parallel spaced guides 10 on which is reciprocally mounted a carriage 11, cover plates 12 being provided for the guides and complementary thereto to contain and guide the carriage 11 for sliding movement on the head frame.

While the carriage 11 is not per so a distinctive and component part of the frame structure of the machine, it is a supporting part thereof for certain operating parts, to be described, which due to the continuous infeeding of the wires, should have reciprocal movement onthe machine, whereby to properly apply the barbs to such continuous infeeding of the wires.

Power and power transmission means The machine is designed to support its power unit and this would take the form of preferably an electric motor A adapted to be supported by and beneath the extension 8 of the head frame 7, see Figs. 1, 2 and 3, and the motor shaft a is provided with a sprocket pinion 7) connected by a link belt 0 with a driving sprocket 13 associated with a clutch member 14, both of which are loosely carried on a main driving shaft 15 journaled in suitable bearings on the head frame of the machine. Cooperating with the loose clutch part 14 is a clutch part 16 having spline and groove connection, not shown, with the main drive shaft 15 and said clutch part 16 has operatively connected therewith a clutch lever 17 pivotally connected r 549 ary frame parts, whereby the sheave wheel at 18 to the bracket 9 and to the opposite end of the clutch lever 17 is operatively connected an operators rod 19 which lies along one side of the machine and guided in a supporting bearing 20.- An operator grasping the rod 19 may move it back and forth for the purpose of shifting the clutch part 16, whereby to connect the main drive shaft 15 in driving relation with the motor A and to disconnect it therefrom.

To the main drive shaft 15' is secured a large spiral gear wheel 21, shown in dotted lines in Fig. 1 and in full lines in Fig.- 4; a wide faced spur gear wheel 22 shown in dotted lines in Figs. 1, 3,5 and 6, and a small spiral gear wheel 23 which is shown in dotted lines in Figs. 1, 3 and 5. These gear wheels are spaced from each other throughout the length of the main driving shaft 15,- as best seen in Fig. 1.

Referring to the small spiral gear wheel 23, it has a meshing relation with a corresponding spiral gear wheel 24 which is shown in full lines in Figs. 1 and 5 and in full and dotted lines in Fig. 3. .This last mentioned spiral gear wheel is secured on a crank shaft 25 which is journaled in suitable bearings secured to the extension 8 of the head frame 7 and to said crankshaft is connected a crank rod 26 and, also, a small gear pinion 27, which is in meshing relation with and adapted to transmit motion to a large gear wheel 28 secured on a driving feed roll shaft 29, see Figs. 1, 2 and 3. To this shaft 29 is, also, secured a sprocket wheel 30 which operates a link belt drive 31 and it in turn transmits motion through a sprocket pinion 32, with which it is connected, to a sheave shaft 33, the latter shaft having ajournaled bearing on stationshaft is immovable in its relation to the slidable'c'arriage 11, supporting partsin association with'and adapted to deliver material to a sheave wheel, to be described, on said sheave wheel shaft.

The said shaft 29 has a gear wheel 34 in mesh with a corresponding gear wheel 35 on a driven feed roll shaft 36, see Figs. 1 and 3, and each of said driving and driven feed roll shafts 29 and'36 have spaced pairs of coacting

feed rollers

37 and 38, respectively. The function of these pairs orsets of

feed rollers

37 and 38 will be described later. They are best seen in Figs. 1 and 3. i l

The driving feed roll shaft 29 has a fixed position, whereas the driven feed roll shaft 36 is movable, that is to say, the shaft 36, as will be seenfrom an examination of Figs. 1 and 3, is journaled in a yoke shaped frame 39 pivotally connected to its support'at 40 to adapt the feed rollers 38 to be moved toward and from the feed rollers 37 and these sets of feed rollers are yieldingly maintained in a cooperative relation by means of an adjustable spring means 41,'see Fig. 3,'which is not imlike that ordinarily employed in machines of this character and for this purpose. The crank 26 which is connected with th crank shaft 25 has an operative connection at 42 with what may be termed the forward end of the slidable carriage 11, whereby to impart a reciprocating movement forward and backward to said carriage. On the carriage -is journaled in suitable bearings a shaft 43 and to said shaft is secured a large gear wheel 44 which is in meshing relation with the broad or wide faced spur gear wheel 22. It is obvious from this arrangement of the broad faced spur gear wheel 22 and narrow faced spur gear wheel 44 that the latteris adapted to have a move ment across the face of the gear wheel 22 during the reciprocationof the carriage 11 while at the same time permitting movement to be transmitted from the gear wheel 22 to the gear wheel 44 and its shaft 43. The said gear wheel 44- has a meshing and driving relation with a small gear pinion 45 connected 46, see Figs. 1, 5, 7 and 8.

The shaft 43. as will be seen from an examination of Figs. 4 and 5, is provided with a crank portion 47 that is adapted to transmit motion to a rock shaft 48 journaled in suitablebearings on the carriage 11 and to said rock shaft 48 is connected a movable cutter to which further reference will be made.

The gear wheel 44 referred to as being carried on the shaft 43 and receiving its power from the broad faced gear wheel 22 is provided on one side with a spiral gear face 49 withfwhich meshes the teeth of a spiral gear pinion 50 connected with a short vertically disposed feed roll driving shaft 51 journaled in suitable hearings on the carriage 11 and said shaft is provided with a wheel 53 carried on a short vertically disposed driven feed roll shaft 54.

r The shaft 51 has a substantially fixed position whereas the shaft 54 is capable of movement in relation to the said shaft 51 and the shaft 51 is provided with a feed roll 55 adapted to have a coacting relation with a feed roll 56"on the shaft 54 and the latter shaft-is journaled in a pivotally supported frame 57 with whi'ch is associated a spring controlled means 58, whereby to yieldingly hold the driving and-driven feed rolls 55 and 56 in cooperative relation. The yielding holding means is common in machines of this character. The mechanism last described is best seen in Figs; 1, 4 and 5. The

feed rollers

55 and 56 are designed to feed the wire from which the barbs are formed and cut, aswill'be hereinafter more fully explained, and the sets of

feed rollers

37 and 38 are designed for the infeeding of the lon- Oil barbed wire; one set of such rollers adapted for feeding the wire to which the barbs are attached and the other wire to be twisted therewith as the barbs have been attached, whereby to complete the barbed wire.

The large spiral gear 21 to which referencehas been made has a meshing and driving relation with a spiral gear wheel 59, see 3 and i, which is connected with and forms part of a preferably conical head 60 which is in turn connected with and forms a part of a preferably vertically disposed yoke 61 which has a trunnion or short shaft 62 at its lower end which is journaled and has a bearing relation with the ball bearings 6. Journaled in brackets 63 depending from the conical head 66 is a shaft 64 and on said shaft between said brackets is a cylinder cam 65, while on one end of said shaft is a gear wheel 66 which meshes with a worm 67 on a preferably vertically disposed and inclined shaft 68, the upper end of which is j ournaled in a bearing 69 on the conical head 60 and its lower end iournaled in a bearing 70 is ,secured to the lower portion of the yoke 61,

see Figs. 3 and 4. To the lower end of the shaft 68 is connected a gear wheel 71 meshing with the tooth portion 7 2 of a disc shaped head 73, forming part of a wrapper, to be described, and also meshing with the tooth portion 72 of said head 73 is a gear pinion 74: carried by a short vertically disposed shaft 75 suitably iournaled in bearings attached to the lower portion of the yoke 61 I and on the lower end of said shaft 70 is a gear wheel 76 in mesh with a gear wheel 77 which is loosely carried on the trunnion or shaft 62 of said yoke 61. Movement is transmitted to the yoke (31 from the main drive shaft 15 through the meshing gears 21 and 59 and as said yoke is revolved the wrapper to which reference has just been casually made rotatestherewith and provision is made in the gearing last mentioned to transmit a revolving movement to such wrapper when it is desired to wrap a completed barb wire thereon. In other words the wrapper revolves with the yoke and in addition is adapted to have a revolving movement within the yoke. The cylinder cam when rotated is designed to impart movement to parts, to be described, for feeding the completed barb wire uniformly across the face of the wrapper during the revolving movement thereof v to wrap the completed barb wire thereon- 1 have described the yoke 61 as being pro vided with atrunnion or short shaft 62 which has a journal bearing in the base 5. At its upper end. the conical head 60 of the yoke, which is in axial alignment with the trunnion or shaft 62, has a journal bearing in the head frame 7 in the manner best seen in Figs. 3 and 4t and. said conical head at its upper end is in communication with an opening 7 8 which is provided in a bracket 79 secured to the upper face of the said head frame 7 and in said bracket is ournaled the sheave wheel shaft 33 on which is carried a double sheave wheel 80 which has certain structural features and functions in a manner to be described.

Barb coiling means The coiling spindle for coiling or wrapping the barb lias'been previously designated as 46, which is continuously revolved, when the machine is in operation, through the meshing of the gears 44 and d5, the latter being connected with said spindle. This coiling spindle is shown in several of the views but its construction and operation will be best understood from Figs. 7. 8, 9 and 10. The ceiling end of the spindle is journaled for rotation in a suitable bearing 81 and its opposite end is iournaled in a suitable bearing 82 and the coiling end of the spindle projects forward of the said bearing 81. This spindle is preferably mounted, for rotation so that its aXis is in alignment with one of the sets or pairs of feeding

rollers

37 and 38 so that the longitudinal strand wire to which the barbs are attached is fed forward by the said sets or pairs of

feed rollers

37 and 38 and thence directed to and through the axially disposed longitudinally opening 83 in the said spindle 46 and in the course of its travel from the

feed rollers

37 and 38 to the spindle the strand wire W is directed under the guiding roller 84 and over the guiding roller 85, see Figs. 1, 3, 5 and 6. The roller 84 is journaled on a frame 86 which is pivotally mounted in connection with an oscillatory spindle 87, the function of which is to be further described,v and the roller is journaled on a substantially fixed support 88.

The coiling spindle is provided with a reciprocally arranged coiling pin 88"which is suitably offset to its axis and the said coiling pin is adapted when reciprocated in a forward direction to have its end projected with= out the coiling end of the spindle, whereby to engage with the wire from which the barbs are formed to coil'or wrap the end of such wire around the strand wire N. This pin is operatively connected with a sleeve 89 which is slidable on the spindle 46 and the said sleeve is formed or provided with an annular flange 96 having a tapered surface 91 with which is adapted to engage a cam 92 secured to one face of the previously described gear wheel 44. In the operation of the coiling spindle and immediately upon the completion of a barb the coiling pin 88 is retracted and this is accomplished by the cam 92 riding against the flange on the sleeve 89 and being connected with the pin 88 retracts the latter as the sleeve 89 is caused to be moved on the coiling spindle. Such movement of the sleeve under the action of the cam 92 is against the tension of a spring 93 int ies

iie

which, as shown, bears against a shoulder on the said sleeve and against acollar fixed to the coiling spindle and abutting with the bearing member 82. Immediately upon the cam 92 ceasing its action the spring 93 acts to return the sleeve 89 and with it the coiling pin 88 into a protruded position forthe pur pose of again engaging thewire from which the barbs are formed and coiling such wire in the form of a barb around the strand W.

The bearings 81 and 82for the ceiling spindle are mounted upon and securedto the carriage 11 and it will be obvious, therefore, that as the carriage is reciprocated to and fro or forward and backward that the coiling spin dle is likewise reciprocated therewith. This is necessary since the wires to which the barbs are attached are fed continuously into the machine and it is during the forward move ment of the carriage and the coiling spindle that the barb is coiled or twisted about the longitudinal wire.

Bar?) wire feeding and barb severing means The wire from which the barbs are formed and severed is designated W and is. fed intermittently into the machine by means of the pair or set of feed rollers and'56 and is directed to the coiling spindle and across the path of its wrapping or coiling end through aguide 94, see Figs. 5, 6, 8, 12 and 13. The forward end of this guide takes the form of a stationary cutter 95, see Figs. 8, 12 and 13, and coacting with this station ary cutter member is a movable cutter member 96 carried in a chuck 97 connected with the rock shaft 48. This rock shaft is so timed in its movement by the crank shaft 43 as to cause the cutter member 96 to move into relation and to coact with the cutter member 95 to sever therefrom the barb length W which has been wrapped or coiled about the wire W; such wrapping or coiling having been accomplished by the end of the coiling pin 88 in the spindle 46, across the path of which the end of the wire WV has been jected by the feed rollers 55 .and 56.

Barb positioning and retention means pro- 1 have described the movement of the longitudinal wires to which the. barbs are attached as being fed into the machine in a preferably horizontal direction and then being directed vertically to the spools on which the completed barb wire is wrapped.

The double sheave wheel 80 over which the 1 ber 98, which takes the form of a dle is located a guiding and positioning memplate supported on a standard 99. This plate 98 has a portion which lies next adjacent to the peripheral portion of the sheave wheel 80 which divides it into two distinct

sheave Wheel portions

100 and 101 and that portion of the said plate lying between the sheave wheel and the coiling portion of the coiling stem is disposed slightly at an angle to the axis of the said coiling spindle, as is best seen in Fig. 8. The longitudinal wire W leaving the coiling spindle 46 is directed alongside the guiding and positioning plate 98, as is best seen in Figs. 7 and 8, and thence over the sheave portion 100 of said double sheave wheel 80, and it is the function of said guiding and positioning plate 98 to hold the barbs W' as they are attached to the wire W with the barbed ends of such wrapped or coiled barbs in substantially or approximately vertical positions,- as is best seen in Fig. 7, whereby thebarbs as they are wrapped or coiled on the longitudinal wire are not permitted to become'displaced but each and all assume and maintain substantialy the same angular positions with respect to the wire upon which they are wrapped or coiled. If this were not so the barbs being coiled or wrapped around an individual wire during the movement of such wire might follow into or assume different positions thereon; however, it is an object of this invention, as stated, to position the barbs on the longitudinal wire and to retain all of the barbs in substantially the same position with respect to such wire and it is the function of the sheave wheel, as I will now explain, to not only retain the barbs in such position but to retain them equidistantly with respect to each other on the wire around which they are coiled or wrapped and to do this I provide the sheave section 1.00 of the double sheave wheel with a plurality of notches 102 and as the longitudinal wire W is advanced with the barbs coiled or wrapped therearound, the successive barbs will enter the successive slots 102, as shown in Figs. 7 and .8, and be held equidistantly on the wire W in rela t-ion to each other until the wire WV as it or wrapped with a second longitudinal wire W The longitudinal wire l/V together with the wire and the barbs WV constitute the completed barbed wire.

The wire W is fed into the machine by one ofthe sets or pairs of

feed rollers

37 and 38 and thence under a guiding roller 84." and ver a guiding roller 85 and then through a guide 103, see particularly Fig. 5, and thence over the sheave portion 101 of the double sheave wheel 80 and then immediately wrapped or twisted with the wire W at the point where the two wires V and W leave the double sheave wheel 80, as is shown in Figs. 7 and 9. From this point the twisted wires WV and Witogether with the barbs which are wrapped or coiled about the wire W, are directed by the wrapper, by means of which the completed barbwire is coiled or wrapped on the spools receiving the same, first being acted upon by means for feeding the completed barb wire uniformly across the face of the spools upon which the barbed wire is wrapped.

One of the advantages possessed by this machine is in the feeding of the strand wires in a horizontal plane and attaching the wire barbs thereto in such plane, then fixing the barbs in a predetermined position by means of the sheave wheel 100 and thence directing the strand wires in a vertical plane, and immediately after these wires leave the double sheave wheel to twist the wires together, holding the wire barbs in their predetermined position, completing the barbed wire, and then wrapping the completed barbed wire on a reel or spool, is, that the barbs are held in position, and the twisting of the strand wires made immeditely after the barbs leave the double sheave wheel, so that in thus feeding the strandwires, attaching the barbs and then twisting the strand wires together, there is little, if any, chance of a displacement or misplacing of the barbs in the completed barb wire, so that in the completed barbed wire all the barbs are equidistant throughout the strands.

Spool carrier and wrapper Reference has been previously made to the disc shaped head 73 which forms part of the wrapper. This head and its tooth portions 72 are journaled for rotation in the lower portion of the yoke 61, see Figs. 3, 4, 14, 15 and 16, and having a pivotal connection with and outside of said head are a plurality of arms or bars 104 which project axially through the said head 73 and transversely of the yoke whereby to provide a collapsible mandrel within the wrapper proper. This mandrel is provided with an axially disposed spindle or shaft 105, the end of which farthest from the head 73 is threaded as at 106. The head of the wrapper, complementary to the head 73 is indicated as 107 and is normally positioned on theopposite side of the yoke to the position of the head 73, and said head 107 is rotatable loosely on a stub shaft 108 having a bearing in a frame part 109 hingedly connected, as shown in Fig. 15, to the base of the yoke 61. Said stub shaft, as well as the head 107, are provided with an axial socket to receive the threaded end of the shaft or spindle 106 and the socket of the stub shaft is threaded so as to receive the threads on the end of said shaft or spindle 106. On the outer end of the stub shaft is a hand wheel 110 by means of which an attendant may rotate the stub shaft to detach it and the head 107 from the threaded end of the shaft or spindle 106 or to attach the same thereto. This may be understood from an examination of Figs. 3 and 14.

.The frame 109 is adapted to be swung inwardly and across the lower end of the yoke 61 whereby to place the head 107 in position to secure the ends of the bars 104, comprising the collapsible mandrel, and also to secure a reel or spool, preferably of wire, which is placed on the mandrel to receive the completed barbed wire, and to secure the ends of the bars 104 in firm and secure position, the head 107 is provided with a plurality of slotted openings 111, see Figs. 3 and 14, into and through which the ends of the bars 104 project; the latter having a tapered formation and wedgelike, see Fig. 3, so that when the head 107 is closed and secured in position the said bars 104 are immovably secured; that is, may not be misplaced but capable of being rotated to impart a like rotation to the spools or reels, whereby to wrap the completed barb wire thereon. To look the frame 109 in closed position, with the parts secured as shown in Fig. 3, a looking means is provided which comprises a slidable bolt member 112 which is adapted to be inserted into and removed from a keeper 113 on the yoke 61, see Fig. 15. The inner end of the slidable bolt member 112 has connection with a roller 114, movable in a suitably shaped slot 115 provided in a camlike member 116 which is oscillatable on the stub shaft 108 and said camlike member has a hand lever 117 provided with a spring held latch 118 which is adapted to have a locking relation with a part of the frame 109, see Figs. 3 and 15. To release the slidable bolt member 112 from the keeper 113 an attendant will grasp the lever 117 and release the latch 118 permitting him to swing the said lever and cause the roller 114 to traverse the slot 115 which is so disposed as to cause a withdrawal of the slidable bolt member 112 from the keeper 113 when the frame 109 may be swung outwardly and back providing, of course, the wheel 110 has been rotated to release the stub shaft 108 from the threaded end ofthe spindle or shaft 106. To secure the parts in position from which they may have been released it is only necessary, will be understood, to swing the frame 109 into closed position and reverse the operation of the lever 117 whereby to cause the slidable bolt member 112 to again enter the keeper 113 and lock the parts in position when the wheel 110 will be revolved to cause a threaded engagement of the stub shaft 108 with the shaft or spindle 106, locking the collapsible mandrel in the head 107.

This mandrel to which reference has been made is designed, particularly, for receiving a wire reel or spool which has been designated X and its designs best shown in dotted lines in Fig. 16. Such a reel or spool may be securec to the collapsible mandrel by first removing the head 107, releasing the bars 104 so that they will collapse and permit the slipping thereon of the reel or spool and in like manner such a reel or spool may be removed from the mandrel by releasing the head 107 and moving itto an inoperative position to allow a spool or reel to be removed from the mandrel with the completed barbed wire wrapped thereon. It is, of course, understood when a reel or spool X is placed on the collapsible mandrel that it is capable of being rotated therewith, when rotative movement is imparted to the bars 104, through the medium'of the tooth portion 72 on the head 73 and that when the said heads 73 and 107 are in closed position, whereby to constitute the complete wrapper, that such spools or reels are firmly held between the two such heads. I

I have previously stated that the gear wheel 77 is loosely carried on the short shaft or trunnion 62 of the yoke 61. This being true and if no provision were made for'holding such gear, then when power was transmitted from the shaft 15 through the

gear wheels

21 and 59 to the yoke 61 the wrapper would ro tate with the yoke but would not at the same time rotate within the yoke, as would be necessary to insure the wrapping of the completed barb wire on a spool or spools secured to the wrapper. I have provided that the gear wheel 77 shall be normally held in a fixed position so that as the yoke 61 is rotated the gear wheel 76 will travel around the gear wheel 77, the latter functioning substantially as a rack, whereby movement may be imparted through the shaft to the pinion 7 1 and through it motion imparted to the tooth portion 72 to impart rotative movement to the collapsible mandrel and, also, movement may be imparted through the tooth portion 72 to the gears 71 and thence through the shaft 68 to the means to be described, for evenly and uniformly distributing the com pleted barb wire on a reel or spool secured to the wrapper. This holding of the gear wheel 77 is accomplished by the provision of a brake drum 119, which is suitably connected with the hub of the gear wheel 77 and coacting with the said brake drum 119 is a brake band 120, see Figs. 3 and 19, one end of which is connected with a clamp 121 fixedly secured at a suitable point to the lower end of the cylindrical member 1 and the opposite end of said brake band is connected with a reciprocally movable rod 121 which extends from within the cylinder to the outside thereof, and to the outer end thereof the said rod has adjustably connected therewith a cam lever 122 which is fulcrumed at 123 to the base frame 5, the free end portion of the said cam lever normally lying in the path of and adapted to be acted upon by the sliding door 3. Having an operative connection with the said cam lever ata point adjacent to where it is connected with the rod 121 is a bell crank lever 124;, which latter has a pivotal connection with a bracket 125 secured to the lower portion of the cylindrical member 1. Connecting to and extending upwardly from the said bell crank lever 124 is a rod 126 and the upper end of said rod is connected with a shaft or spindle 87 which, as previously described, has an operative connection with'the frame carrying the

guide rollers

84, 84 and 85, 85. This rod 126 is normally sustained in an upward position by means of a spring 127, one end of which is connected with the rod and the other to the frame extension 8 of the head frame 7. The spring acts to lift and hold the rod 126 and through the action of-the bell crank lever 124 to apply power to the brake band 120, whereby to hold the gear wheel 77, and allowing the gear wheel 76 to move therearound and the latter to be rotated by reason of its meshing relation with the teeth of the gear wheel 77, as has been explained.

Attention is called to the feeding of the wires WV and V7 by the sets of

feed rollers

37 and 38, first under the guiding

rollers

84, 84, and thence over the guiding rollers 85, 85, if and when unusual tension is applied to the barbed wire as it is reeled up by the wrapper, the uiding roller 84: and its frame 86 are lifted against the tension of' the spring 127 which will force the rod 126 downwardly and release the brake band 120 and, also, release the gear wheel 77 and permit it to run loose and thereafter and during the rotation of the yoke no rotat'ive movement is imparted to the wrapper within the yoke as it rotates with the yoke and then immediately when said tension in the completed barb wire is relieved, the spring 127 immediately acts toagain lift the rod 126 to actuate the brake band 120 and hold the gear wheel 77 in a fixed position.

I have described the strand wires W and W being fed by the sets of

feed rollers

37 and 38 and directed the respective wires first under the guiding rollers 84, 8%, and thence over the guiding rollers 85, 85. If and during the wrapping of the completed barbed wire there should be an unusual tension on the wires W and and if the wrapping is not uniformly with the feeding of such wires by the

rollers

37 and 38, the frame 86 will be lifted against the tension of the spring 127, which, through the connections described, will force the rod 126 downwardly and release the brake band 120, and also release the gear wheel 77 and allow it to run loose and thereafter and during the rotation of the yoke 61, no rotative movement is im parted to the wrapper within the yoke, as it rotates with the yoke, then immediately when said tension of these wires is relieved, the

spring 127. immediately acts to lift the rod 126 which will result in operating the brake band 120 and retain the gear wheel 77 in a fixed position. i r 7 Assuming that the atteu d ant desires to remove a completed reel of barbed l wire and toreplace it with an empty reel, it is possible that the wrapper may not have stopped in a position to enable him, after sliding the door 3, to getpossession of the hand wheel and if such were the case and the brake band was not released, he would find it'diiiicult to rotate the yoke whereby to permit him to remove the head 107 of the wrapper so as to take oil a full reel and replace it with an empty reel and so it is provided that when the attendant slides the door 3 from across the opening 2 that the door will ride under and engagethe free end of the cam lever 122 which will actuate the bell. crank lever 12-1 and pull the rod 126 downwardly so as to release the brake band and thereby with considerable freedom and ease the attendant may rotate the yoke to a position to make it easy and convenient to move the. head 19. so as to enable the removal'of a full reel from the wrapper and to replace it v'th an empty reel. On closing the door the *ing 121' will act to restore the parts and to st the brake band for the purposes explained. 7

Attention is called to a safety measure which is introduced into this machine which is not present, so far as I know, in machines of like character. By the arrangement of the sliding door 3 in the cylindrical frame, it is practically,impossible for an operator or an attendant to get his hands caught either in the yoke. or the wrapper, orto beiome snagged when he attempts to inspecteitherthe rolling up of the barbed wire on the wrapper or to get to the wrapper to remove a completed reel and replace the same with an empty reel. On examining Fig. it will be observed that the sliding door may be openedfor a very short distance before it comes into contact with the wrapper 122. which contact would stop the rotating oi the yoke and the wrapper. However with such sinall degree of opening the operator permitted to look into the cylindrical member to see how the wrapper is operating, if he cares to do so, but if the door 3 is moved sulficiently to come into engagement with the lever 1.22, such lever will operate, as previously explained, to actuate the l ake band and release the gearing which imparts movement to the yoke and the wrapper. Therefore, it will be observed that a. saf y measure wheii the door is opened, the yoke ceases to rotate and the wrapperceases to 0? tate with the yoke.

B (10*?) wire feeding and cZc'stributv'n-g means trrmnions 128 and extending down into the body of the yoke is a tubular member 129 from the lower end of which isisupported a star guiding wheel 130. The tubular member has connected therewith a roller 131 which rides on the cylindrical cam 65. It obvious that when the cam 65 is rotated through the gearing which connects it with the shaft (38 that oscillatory motion will be imparted :to the tubular member 129 so as to move the star wheel back and forth above the wrapper. The barb wire comprising the strands 1V and lv with the barbs l 72 thereon leaving the double sheave wheel 80 pass down and through the tubular member 129 and hence over tl e face of the star wheel 130 whereby during a sidewise or reciprocal movement imparted to the latter will feed or uniformly lay the completed barbed :wire ona spool carried by the wrapper, on which the completed barbed wire is wrapped. The said tubular member 129 and its star wheel moving on the fulcrum provided by the trun nions 128. :It willbe understood from the foregoing description that the feeding means just described for the completed barb wire is operative when the wrapper isirotating within the yoke. It being further understood that the yoke is adapted to be rotated carrying the wrapper with it in its orbit; and that during such rotative movement of the yoke the said wrapper is adapted to be rotated within the yoke. 55

Brake mechcmz'sm for the yolce cmd elements carried thereby In Figs. 3, 4 and 18 I have shown a brake drum 132 which is preferably connected with the yoke 61 just below the conical head and adapted to have a braking action on said brake band, a brake shoe 133 carried by an arm or lever;.13t having a pivotal connection 135 within the cylindrical member 1. To the free end of the lever or arm 134i is con nected a link 136 which in turn has connection with a lever 137 pivoted at 138 to a' bracket 139 secured to the cylindrical member 1 and the free end of said lever 137 is in operative connection with the operators rod 19. These parts are so arranged that when the operator Shifts the rod 119 to declutch the power from the driving shaft 15 that the brake shoe 133 set against the drum 132 so as to bring to a stop the yoke 61 and the elements carried thereby.

i In general It'is believed that the operation of feeding the pair of strand wires 1V and 11 into the machine, the attaching of the wire barbs to the strand wire TV, the positioning of the ends of the barbs, the definite and predetermined location of the wire barbs on the strand 7, the twisting of the strands WV andd v im: mediately after the positioning and location parts of the machine are declutched from the driving shaft without further detailed description.
