Referring now to the various characters of reference on the drawings, and first to Figs. 1 to inclusive. The base of the machine is indicated at 1 having an upwardly extending annular housing 2 formed integra' therewith in which the mechanism of the machine is mounted. The base of the machine is provided with bearings 3 in which the driving-shaft 4 is journaled, having a pinion mounted thereon as at 5, meshing with a gear 6 which is formed with a central open-.-
ing 7 and radial notches 8. One side of the gear 6 is recessed as at 9 and provided with an annular shelf 10 to which is attached by means of bolts .1 a spider 12 having a hub 13 and radial openings 14, said radial openings registering at their outer ends with the notches 8 in the gear 6. An opening is formed centrally in the hub 13 of the spider 12 for receiving a bushing 15 adapted to be mounted to rotate on a stationary main-shaft 16 which is supported at one end-as at 17 in the annular housing 2 and at the opposite end in the boss 18 of a front bearing-plate 19 which is secured in spaced relation by means of bolts and washers to the front of the machine.
A projection 20 extends outwardly from the central portion of the spider 12 between each of the radial openings 14, each having a radial groove 21 formed therein on its outer face and provided with a plurality of aligned threaded perforations 22, for receiving the screws 23 for attaching the revolving dies or loop formers 24 thereto, upon which the wire is bent as they are revolved concentrically by the rotation of the spider 12 around the main-shaft 16. Said loop formers being each provided with a tongue 25 adapted to extend into the groove 21 to prevent lateral displacement.
The bushing 15 extends outwardly beyond the face of the spider 12 and has mounted thereon in vertical alignment with the loop-formers 24 a center-former 26 notched at four places around its peripheral edge as at 27 to receive the U- shaped bends between the loops formed in making the reel ends 28 and a collar 29, the two being attached to the hub 13 of the spider by means of bolts 30. A slide-way 31 is formed in the collar 29 for receiving a reciprocating shear-blade 32, provided with a set-screw, the projecting reduced end 33 of which engages a pin 34 adapted to be actuated by means of a spring 35 mounted in a socket 36 which is notched as at 37 to receive the reduced-end 33 of the set-screw. The outer end of the shear-blade 32 is arc-shaped as at 38 and adapted to engage a roller 39 having its axle 40 mounted in a holder 41 which is attached to the front of the boss 18.
A slide-way 42 is formed in the hub 13 of the spider at the inner ends of each of the radial openings 14, each being in alignment with one of the four notches 27 of the center former 26, and adapted to receive slide-bars 43 having reduced outer ends 44 grooved on their outer side faces as at 45 and each provided with a bifurcated inner end in which is mounted a roller 46 for engaging a cam 47 which is attached to the inner face of the annular housing 2 of the machine and adapted to project the slide-bars forward when they come in contact with the same and to bend the U-shaped portions of the reel ends laterally. The axle or pin upon which each roller 46 is mounted projects from one side of the bifurcated end of each slide-bar as at 48 to engage a cam 49 for retracting the slide-bars 43 after they have been projected forwardly by the cam 47. This cam 49 is also attached to the inner face of the annular housing 2 of the machine as at 50 near the cam 47 as more clearly indicated in Fig. 4 of the drawlugs.-
At an intermediate point between each of the radial openings 14 formed in the spider 12 are perforations 51 which register with perforations 52 in the web of the gear 6. These four aligned sets of perforations are each adapted to receive a stub-shaft 53. The front ends of each of these stub-shafts 53 are formed with reduced threaded ends 54 .for receiving nuts 55, these nuts being beveled on their inner faces to engage beveled surfaces around the perforations 51. A rectangular head 56 is formed integral with each stubshaft 53 at their rear ends adapted to engage the inner face of the gear 6 and to be connected thereto by means ofdowel pins 57 to prevent rotation of the same.
A crank-arm 58 is pivoted at one end to each of the four stub-shafts 53, between the web of the gear 6 and the spider 12, the two being spaced apart at this point a suflicient distance for this purpose. The opposite ends of the crankarms 58 are attached and keyed as at 59 and also riveted as at 60 to the intermediate portions of the axles 61 for the cam-rollers 62 which are mounted in the bifurcated ends of the pivoted die-carriers 63, said cam-rollers being adapted to engage the cam surface 64 of a cam-plate 65 which also forms the front housing plate for the machine. Each of the four die-carriers 63 and cam-rollers 62 are secured on the axles 61 by means of a screw-threaded keeper 66 which is threaded into a socket 67 formed near one side in the outer end of the axle,- said keeper being provided with a fiat head which is counter-sunkin the end of the axle. A plurality of perforations 68 are formed in the flat heads of each of the keepers to receive a set-screw 69 in one of the same after adjustment. The head of the keeper extends beyond the edge of a portion of the circumference of the axle into an arc-shaped groove 70 formed in the die-carrier 63 thereby allowing the die-carrier a limited lateral swinging movement.
A bending-die 71 is attached to each of the die-carriers and adapted to swing therewith and to revolve eccentrically around the main-shaft 16 at varying distances therefrom. These bending-dies being of blunt wedge shape or substantially triangular in plan, each being provided with an extending toe 72 at their apex portions and a tongue 73 on their inner side faces, adapted to extend into a recess 74 formed in the outer side face of the pivoted die-carrier 63 to prevent lateral displacement thereon.
The swinging eccentrically revolving bendingdies 71 are each secured to the die-carriers 63 by means of a bolt 75 which is keyed thereto as at 76 near its head and extends transversely through the die-carrier and inwardly beyond the same, being threaded at an intermediate point as at 77 to receive a nut 78. Each of the bolts 75 are further provided with a smooth extending end portion 79 to which is pivoted one end of a link connection 80, the opposite end of said link connection being attached to the head 56 of the with perforated lug projections 88 and 89 re-- spectively for receiving one end portion of an adjustable connecting rod 90 having nuts or collars 91 and 92 mounted thereon, adapted to engage opposite sides of the lug projection 89, and a spring 93 is mounted on the rod 90 interposed between the lug projection 88 and the collar 92 for normally holding the collar 92 in engagement with one side of the projection 89, while the collar 91 is normally spaced apart from the opposite side of said lug projection. The
opposite end of the rod 90 to that on which the collars are mounted is formed with an eye 94 and is pivoted on the smooth end portion 79 of the bolt 75. The adjustable bolt 83 which forms the pivotal point for one end of the link connection 80 may be adjusted in the T-shaped slide-way 81 of the stub-shaft head 56 in order to hold the swinging eccentrically revolving bending-die 71 and die-carrier 63 in the required angular position in relation to the crank-arm 58 so that the bending-die 71 will be brought into proper crimping engagement with the wire at the desired time. The pivotal points for the ends of the link connections 80 are however in substantially fixed spaced relation to each other at all times after adjustment, the spring 93 and the collars 91 and 92 on the rod 90 at each side of the lug 89 being only for the purpose of allowing a certain amount. of play or resiliency to the link connection while it is holding the swinging end of the crank-arm 58, eccentrically revolving bending-die 71 and die-carrier 63 in the desired position thereby limiting their changing angular movements during the operation of the machine.
As the gear 6 and spider 12 are rotated the,
cam-rollers 62 engage the cam surface 95 which for greater durabilityis preferably formed at this point of a hardened steel block 96 set into the cam-plate 65 and provided with an inclined abutment 97 for engaging the inclined edge 98 of the front bearing plate 19. The crank-arms 58 are keyed to the axles 61 for the cam-rollers 62, while the die-carriers 63 are pivoted on said axles, as each of the cam-rollers travel over the cam-surface 95 the eccentrically revolving bending-dies 71 are each in turn swung inwardly to wire bending engagement between two of the concentrically revolving dies or loop-formers 24 and are each retained in this position by means of the cam until the gear 6 has traveled about two fifths of a revolution, during this time of travel a similarly mounted cam-roller has traveled over the cam surface 95 and swung another eccentrically revolving bending-die into clamping engagement with the wire between a pair of concentrically mounted revolving dies or loop-formers 24. This wire crimping operation is repeated four times during each revolution of the gear 6. After the cam-rollers 62 pass over the highest portion of the cam which crimps the wire 99 to form loops 100 with U-shaped bends 101 between the same which are offset as at 102. The eccentrically revolving bending-dies 71 are released from engagement with the crimped wire by means of the projecting studs 103 which are formed integral with the intermediate portion of the axles 61 coming into engagement with an arc-shaped guide plate 104 which is secured to the inner face of the annular housing 2. The studs 103 first engage the lower rounded end of the guideplate 104 and then ride over theouter edge thereby swinging the crank-arms 58, die-carriers 63 and eccentrically revolving bending-dies 71 outwardly and holding them in this position until the studs pass off the opposite end of said guide- 'plate. At this point the cam-rollers will again be in engagement with the camsurface 95 and the operation above described will be repeated.
It will be noted that the cam-rollers 62 as they pass over the cam surfaces 64 and 95 will be rotated in a clock-wise direction when viewed from the front of the machine, this has a tendency during the crimping operation to swing the diecarriers 63 against, the lower sides near the inner ends of the radial openings 14- formed inthe spider 12, to allow for this deflect and to bring the swinging eccentrically revolving bending-dies into proper alignment during the crimping operation hardened steel blocks 105 are set in the side of the radial openings at this point.
The operation of the machine is continuous, the wire 99 being drawn through straightening rolls 106 of well known construction which are mounted in a frame 107 thatis adjustably secured to the machine. 1
After the loops 100 have been formed with the connecting U-shaped bends 101, and oifset as at 102, it is necessary to continuously eject the formed members during the crimping operation detailed description of my machine, I will now describe the operation:The wire 99 is supplied to the machine from a large coil or reel (not shown), located near the machine. The upper set or row of straightening rolls is released in the usual manner to allow the end of the wire to be inserted between the upper and lower sets of rolls and then advanced manually until it engages the rounded portions of a pair of the conccntrically revolving dies or loop-formers 24, the drive-shaft 4 is then rotated preferably manually by means of applying a wrench to its forward end as indicated in dotted lines in Fig. 1, until the wire is clamped between one or more of the swinging eccentrically revolving bending-dies 71 and one or more pairs of the concentrically revolving dies or loop-formers 24, the wrench is then taken off the drive-shaft and the upper row of straightening rolls returned to the position indicated in the drawingsthe drive-shaft 4 can then be driven by any suitable power as by a motor connected to the rear end of the same.
The gear 6 with the spider 12 attached thereto carrying the concentrically revolving dies or loopformers 24 and coacting crimping mechanism are then continuously rotated in a counter-clockwise direction when viewed from the front of the machine. The concentrically revolving dies or loopformers 24 with the center-former 26 are arranged in cruciform outline with the inner ends of the radial openings 14 in the spider 12 between the arms of the same. These radial openings in the spider are to .allow clearances for the swinging ends of the crank-arms 58, axles 61 on which the cam-rollers 62 are mounted. and
and mechanism attached thereto are held in the raised position by means of the stud projection 103 of the axle 61 engaging the top surface of the arc-shaped guide-plate 104 and the two bending-dies at the left-hand side of the figure are means of the cam-rollers engaging the high portion or smaller diameter of the cam surfaces 95 and 64, while the one at the lower right hand side of the figure has just been released from crimping. engagement with the wire by means of the stud projection 103 engaging the lower curved surface of the arc-shaped guide plate 104.
As all of the four swinging eccentrically re- 'volving bending-dies are operated in the same jection 103 of the axle 61- engaging the top surface of the arc-shaped guide-plate 104, as the gear 6 with the mechanism attached thereto continues to rotate in acounter-clockwise direction, the stud projection passes off the left hand end of the guide-plate 104, the cam-roller 62 at this point will then be in engagement with the camsurface 95 of the cam-block 96 and will swing the movable end of the crank-arm 58 with the die-carrier and bending-die into crimping engagement with the wire between two of the loopformers; the apex portion of the swinging eccentrically revolving bending-die forming U-shaped bends 101 between the loops in the notches 2'7 of the center-former 26 with the point of the toe 72 extending slightly into the inside edge of the boss 18, which is preferably reinforced at this point by-means of an arc-shaped plate 72. To
allow the extending toes 72 of the bending-dies '71 to clear the front bearing plate 19 while they are being advanced into crimping engagement with the wire just before reaching the arc-shaped plate '72, an inclined channel is formed in the inside of the said front bearing-plate as at 72" which extends from the vertical side edge of the plate to a circular opening formed therein as at 72". This circular opening being for the purpose of allowing the operator to note how the bending-dies engage and crimp the wire between the loop-formers. The cam-rollers 62 and bending-die are held in this position until the gear has rotated about two-fifths of a revolution, during. which time another bending-die has been swung into crimping engagement with the wire 99 by means of the following cam-roller-62 engaging the cam-surface 95, after passing over the small diameter of the cam surface the stud projection 103 comes in contact with the lower curved end of the guide-plate 104 and then rides over the outer edge'thereby swinging the crank-arm 58 and bending die 71 with the parts attached thereto outwardly into the position they assume at the top of the figure. The four eccentrically revolving bending-dies operate in sequence, the movements being the same for each rotation of the gear 6, the link connections 80 being adjusted so as to swing the die-carriers and bending-dies operation.
With this form of reel'end a center-plate (not shown) is used to secure and lock the core members to the ends, for this purpose the U-shaped connecting portions between the loops have to be offset at an angle of substantially 45 to receive the bent ends of the core members. This operation will be more clearly understood by referring to Figs. 3, 4 and of the drawings.
Mounted in each of the four slide-ways 42 formed'in the hub 13 of the spider 12 is a-slidebar 43. The outer ends of these slide-bars are held in crimping engagement with the wire by reduced and extend into the notches 27 of the center-former 26, while the rear end of each slide-bar is bifurcated and has a roller 46 mountecl-therein for engaging a cam 47. This cam 4'1 is adaptedito project the slide-bars forward and oifseteach U-shaped bend 101 from the position shown in dotted lines in Fig. 5 on the apex portion of the eccentrically revolving bending-die over the extending toe 72 into the position indicated in full lines in said figure. After passing over the cam 47 the projecting ends 48 of the axle or pin on which rollers 46 are mounted engages the cam 49 and retracts the slide-bars 43.
During each revolution of the machine one of the U-shaped' oifset portions is sheared or nicked by means of a reciprocating shear-blade 32, which is mounted in a slideway 31 formed in the collar 29 opposite one of the slide-bars 43 and in staggered relation thereto. This shearing is done while the bending die is in crimping engagement with the wire, with the cam-roller 62 in its lowest portion of the cam surface 64, and while the end of the slide-bar 43 is projected forward over the eccentrically revolving bending-die by its en-' gagement with the cam 4'1. The shear-blade at this point is projected into cutting engagement with the wire by means of the roller 39 and after passing the same retracted by means of 'a. spring 35 as clearly indicated in the figures above mentioned.
In the shearing operation the wire may be cut off or it may be nicked deep enough so it can be easily broken off after it has'been ejected from the machine onto the tubular holder. The cutting or nicking of the wire being preferably at an angle thereto so that the inclined side of the ends will overlap thereby forming a better joint.
After the crimping, offsetting and shearing operations, the formed reel ends have to be auto-'- matically ejected from the machine, this is accomplished by means of a plow 108 which is adapted to engage the rear side of the loops between the concentrically revolving dies or loopformers 24 and the rotating center-formers 26 and bending said loops laterally through the opening 109 formed in the boss 18 where it is received spirally on the boss and advanced to the tubular holder 110.
After the machine has been started it is continuously driven thereby pulling the wire 99 between the straightening rolls until the reel-of wire from which the reel ends are formed has been used up. Another supply reel is then substituted and the end fed into the machine as above described and the operation continued.
Referring now to the modification illustrated in Figs. 26, 27, 28, 30, 31 and 32 which shows a machine for forming the reel ends entirely of wire. In this machine the base, annular housing, gearing and movable-die actuating mechanism are the same as heretofore described and the same reference numerals will apply thereto.
The fixed main-shaft 111 has its rear end supported in, the bearing 17,, its forward end however, stops short of the face 112 of the spider 113. A holder 114 for receiving the formed reel ends has its inner portion slightly reduced and partially threaded and screwed into the forward end of the main-shaft 111, said reduced portion of the holder 114 passes through and is supported by the front bearing-plate 115. A center-former 116 is mounted on the reduced inner portion of the holder 114, between the forward end of the main-shaft 111 and the front bearing-plate 115,
upon which the wire is bent to form a closed ring for. the central spindle bearing opening 117 for the reel ends 118. This spindle-bearing opening is necessary to enable the reel when formed and wound with barbed-wire or wire to be placed and secured in wire reeling and unreeling positions.
The reel ends formed in this machine have four radial arms, the outer looped ends 119 of each arm being. pear-shaped with their inner portions which connect the central spindle opening 117 brought together and then bulged outwardly as at 120 to form a closed eye, the sides of which serve as abutments or shoulders between which the ends of the tie-bars forming the core members of the reel are attached.
The hub 121 of the spider 113 is perforated centrally for receiving a bushing 122 which is mounted on the main-shaft 111. The bushing has a flange 123 at its inner end provided with.
cut out portions 124 for receiving the heads of nuts 125 screwed on the inner ends of the shafts 126 of oval shaped intermediate formers 127 upon which the eyes or bulged out portions 120 are formed. These intermediate formers '127 are cut out as at 128 to receive the edges of the centerformers 116 while their shafts 126 are keyed as at 129 to the hub 121 of the spider 113 to prevent rotation.
The manner of attaching the pear-shaped concentrically revolving dies 130 to the spider 113 is the same as described for the machine illustrated in Figs. 1 to 25, the spider being provided with the same projections 20, radial grooves 21, threaded perforations 22 and screws 23 for attaching the pear-shaped concentrically revolving dies or loop formers 130 to the spider in radial alignment with the intermediate formers 127. The eccentrically'revolving bending-dies 131 are however somewhat differently formed, but are attached to the die-carriers 63 and actuated in the same way as heretofore described. These eccentrical- 1y revolving bending-dies 130 each have inwardly inclined straight side faces 132 adapted to bend the wire in forming the pear-shaped loops 119 on the concentrically revolving loop formers or dies 130. The inner end of said inclined sides are formed with arcuately and inwardly extending portions 133 for crimping the wire on the sides of the intermediate formers 127 to form eyes or shoulders on the arms, and a short curved inner end surface 134 connects the arcuately formed portions for bending the wire on the centerformer 116 to form the central bearing opening 117.
In this construction I prefer to sever the reel ends in thecentral portion of one of the eyes or bulges as at 135 and for this purpose a shearblade or cutter 136 is mounted on one of the eccentrically revolving bending-dies 131 and secured in position by means of a keeper 137, the.
they are ejected by means of a plow. 138 which engages the rear side of each arm of the reel between the pear-shaped concentrically revolving dies 130 and the intermediate oval shaped intermediate formers 127 and bends the arms laterally over the side edge of the front bearing-plate 115 and onto the holder 114 where the reel ends are received spirally, from which point they may be removed as heretofore described.
