MACHINE FOR MAKDN'G WIRE FABRIC.

Application filed May 11,

T 0 all whom z' may concern:

Be it known that we, HERBERT E. WHITE and THOMAS H. KANE, citizens of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Machines for Making Wire *abric, of which the following is a specification.

lThis invention relates to wire working, and more particularly to an improvement in machines for making wire mesh reinforcementof the type used in building concrete roads.

To that end the invention contemplates a novel mechanism, and association of instrumentalities, so designed and organized as to provide a practical and reliable machine having means for handling the line wires and the cross wires in a manner to automatically assemble them accurately and uniformly in position to be joined or con-- nected, thereby rendering the machine capable of producing wire mesh of a standard construction, and also in large quantities at sufficient speed for a large commercial out- A further and more specific object of the invention is to provide a novel stapling or tie-forming unit, for insuring the proper connection between the line wires and the cross wires of the fabric or fmesli In that connection it is proposed to provide a unit which may be duplicated as desired and of a construction permitting standardization of parts, at the same time making it possible `,to utilize any desired number of units in alined relation to produce a fabric of the desired width. It is, therefore, one of the distinctive features of the invention to provide a stapling or connectingunit for each of the line wires, the same being so designed and equipped as to facilitate the passage of the line wire through the machine, while at the same time assist- I, ing in the handling and manipulation of the staple or tie preparatory to its -final clinching about the cross wire, thereby connecting the latter to the line wire.

The invention also has for its object a 1922. serial No. 566,177.

novel consolidation of the and the means for making cross-wires, whereby tie-forming unit,

and feeding. the the latter in proper cut lengths, and pre-straightened, will be fed singly to position against the line wires at the proper time and in the proper spacing for being fastened to the line wires by the clincher-action of the fabricating unit. In that phase of the invention, the latter also contemplates the employment of a cross-wire making and feeding unit having a large producing capacity and adequate means for feeding the Asingle wires at the desired Speeds..

l.A further object of the invention is to provide a simple and practical arrangement of auxiliary devices for, feeding and handling the line and cross wires in proper synchronism with the operation of the stapling units.

With the abovevand other objects in view which will morereadily appear as the nature of the invention is better understood, the same consists in the novel construction, combination7 and arrangement of parts hereinafter more Afully described, illustrated and claimed. y y

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which:

lin the making of wire fabric or wire mesh of the type used in the reinforcement of concrete roads, it is desirable to utilize line wires of relatively heavy.gauge to be embedded lwithin the road bed and held in proper spaced relation by a series of transversely disposed cross wires, and it is the purpose of the present invention to provide a machine with adequate facilities for producing a wire mesh fabric of this type in commercial quantities. lfn that connection it is proposed to provide a novel assembly of devices for handling the wires, and novel means for connecting or joining the same in a thoroughly rigid and practical -manner to insure the proper spacing thereof from the time of manufacture until placed in the road bed for use. rllhe type of wire mesh referred to is shown in Figure 11, the saine comprising the relatively heavy line wires W and the lighter cross wires W joined at their intersections by the clinched staples S.

llt will be observed from Figure 1 of the drawings, that a machine of the type referred to primarily includes in its organization a novel fabricating unit designated generally by the letter A and which fabricating unit includes those instrumentalities which provide for feeding the line wires and the cross-wires into. proper crossing relation,

l and the means for positioning a staple at the intersection of the line wire and the crosswire and clinching the same about the two, thereby edecting a fastening or union, at

each point of intersection. Also the inachine includes in its organization a suitable feeding device B for the line wires, and-a cross-wire supplying unit C having means for making and feeding the cross-wires to the fabricating unit in single order at the required intervals. Suitable operating connections are provided between the fabricating unit and the cross-wire unit to eect the operation of these units in unison and proper synchronism` thereby to obtain acrecente curacy and reliability in the correlated functions.

Considering first that part of the machine embodying the fabricating unit A, it will be noted that the same includes the particular instrumentalities which function to intermittently assemble the line and cross wires and place the fastening staples thereover whereby the legs of the staples may be finally clinched about the cross-wires to complete the joint. These instrumentalities consist principally of the feeding device B for the line wires, the staple carrier 1, staple plunger die 2, anvil clinching die 3, and the cross-wire carrier a. llihe manner in which they are preferably arranged in a machine organization is clearly shown in Figures 1, 2 and 3 of the drawings, and will now be more particularly referred to, the description of the details of each being hereinafter more fully set forth.

'llhe upper and lower dies 2 and 3 which have been respectively designated as the staple-plunger die and the anvil-clinching diev are carried by the oppositely working jaw members 5 and 6 mounted to reciprocate in the frame F of the machine. The upper jaw 5 may be suspended by the links 7 from the lever arms 8 on the shaft 9; and, as shown in Figure 2, this shaft may also be equipped with the od-set crank arm 10. Said crank arm is disposed at an angle to the arms 8 and is pivotally connected as at 11 with the reciprocatory rod 12 whose lower end is also pivotally connected, as at 13, with theV rocker lever 1e located at the bottom of the frame F.

'llhe lever 14 above referred to may be ro-ckably supported as at 15 and preferably carries on one face thereof the spaced oppositely disposed bearing rollers 16 adapted to be engaged by an operating cam 17 on the. main actuating shaft 18 suitably journalled in the lower part of the frame. 1n addition to carrying the operating cam 17, this shaft 18 also carries the eccentrics 19 adapted to receive the bearings 20 of the supporting or connecting rod element 21 which pivtally engages as at 22 with the lower jaw 6. For the purpose of operating the said actuating shaft any suitable and convenient means may be utilized, such for instance as the driving sprocket 23 and chain 2t, as shown in Figure 1.

'llhe jaws 5 and 6 which carry the fabricating instrumentalities 2 and 3 heretofore referred to may be of any required length in orderl to make the desired width of finished fabric, and, for the purpose of properly feeding the line wires W between the jaws to insure accuracy of operation in connecting the line wires and the cross wires a check device D may be employed at the feeding-in side of the fabricating unit A, as shown in Figure 2. rJlhis check device permits the intermittent advance of the line wires upon the forward reciprocating movement of the feeding device B after the same leave the rolls E of the straightening unit G, and prevents backward or retrograde movement of the line wires upon the backward stroke of the'feeding device. After passing through the checkdevice D, and issuing from the guide D thereof the line wires W are delivered into the zone of action of the fabricating unit A which connects the cross wires W therewith.

In connection with the delivery of the cross wires W to the fabricating unit from the cross wire supplying unit C, it may be observed that the cross wire carrier 4 previously referred to may be in the form of a shiftable carrier arm 25 h-aving thel slotted end portion 26 slidably engaging over the shaft 27 while its oppositev end pivotally connects as at 28 with a swinging throw link 29. This throw link 29 is pivotally supported at its lower end 30 on the base part of the machine, thus producing in effect a toggle 25-,-29 which operates to give the cross wirecarrier the necessary upward swinging movement, whereby the cross wire W resting in the cradle. formed by the olfset or projection 31 of the arm 25 will be delivered in position above the anvil clinching die 3 so that as the latter rises itz will` firmly place and hold the cross wire in position against the line. wire during the operation of clinching the ends of the staples.l y

As previously set forth, the fabricating unit A includes the tie forming or clinching means which essentially consists of the staple carrier 1, staplei plunger die 2 and the anvil clinching die 3 all of which cooperate to place the staple astride the crossing points of the line and cross wires, automatically, and subsequently effect the complete and secure union between the wires ,by upsetting the ends of the staple on the anvil die and clinching the sanie abou-t the cross wires while the bight of the staple embraces the line wire.

Referring first to the structural fea-tures and characteristic of the staple carrier 1, it may be observed that the same constitutes a part of 'a staple magazine (not shown) and serves to deliver the staples in single order to the upper die 2 at proper intervals during the fabricating operation. As will be observed from Figure 4 for example, the said staple carrier may consist of a rela- -tively shiftable and yieldably mounted body the shoe 32 to be normally pressed forward against the face of the reciprocating stapleplunger die 2, vand yet permits of the same being readily forced backward upon the descent of the plunger to insure of one of the staples S being carried downwardly therewith. The upper part of lthe body of the staple carrier is preferably provided with an inclined carrier bar 36 upon which the staples are hung whereby they may slide downwardly by gravity onto the delivery section 37 which is preferably formed into the curved or arc-shaped formation shown and' is of such cross sectional design as to reduce the friction on the traveling staple after it leaves the main part of the bar 36. That is' to' say, as the delivery section 37 approaches the horizontal plane it is preferable to eliminate as much resistance or friction as possible .to permit the free sliding of the staple toward the die 2 so as to insure the proper feed of the staples thereto.

Therefore, as will be observed from Figures 4, 8, and 9, the ysaid delivery section 37 of the carrier bar has its side walls grooved or cut-away to provide in effect the spaced guiding beads 38 at the sides of the section whichvolfer a comparatively small area of contact or engagement for the sides or legs of the staple while the top edge or .corners of the rib are also cut-away so as to leave only a single top bead 39, thereby reducing the area of contact between the top of the section and the bight or loop end of the sta le. Beneath the eXtreme end of the part 3 the end of the basel of the carrier is provided with the staple clearance notches 40 and the upper corners of the base at each side'of the notches is formed with the inclined plunger die engaging shoulders 41 for permitting the free descent of the plunger 2 when the shoulders 42 thereof engage with the carrier and shift it horizontally out of the way.

The inclined die shoulders 42 on the staple plunger die 2, are located on the relativelyA separate spring legs 43 which are cut away at their .lower inner ends to provide a relatively flaring line `wire receiving mouth 44 and line wire receiving recess 45, while the face of the plunger, between the shoulders 42 may be formed with a substantially arched recess constituting a staple receiving seat 46. This seat as well as the shoulders 42 may be duplicated on both faces of the die to permit of the reversing thereof when desired.-

' The upper end of the plunger die 2 may be secured in any suitable and convenient manner to the upper jaw 5 of the machine, and for the purpose of varying the spacing of the legs43 thereof to regulate the width of the line wire receiving recess 45 and the staple seat 46, and also tdcompress the legs to grip lthe stapleafter it leaves the magazine, the lower ends of the legs 43 pass between the compression heads H of the adjusting or tensioning devices 47 which may be of the nut and screw type shown in lFigure 7 of the drawings.

rllhe anvil die 3 which cooperates with the plunger die 2 to clinch the legs of the staples S to the cross wires W may be carried by the lower jaw 6 in any suitable and convenient manner, as for example, by the clamping bar 48 and the wedge lock 49. As will be seen from the assembly shown in Figure 4 the said die preferably fits into a socket 50 formed between the bar and the jaw 6, and

the latter, at one side of the die is provided receiving groove and in a lower plane. At

each end of the cross wire receiving groove 53 the die head is formed withthe clinching y grooves 54 which lie in a plane below the bottom of the groo-ve 53 and receive and direct upwardly the lower ends of the staples S which are preferably bent slightly before being placed in the magazine to insure the curling up thereof about the cross wires as the plunger die and anvil die complete their opposing strokes. rllhe rear edge of the die 3 is also provided with the upwardly inclined face 55 for. assisting in the delivery of the cross wire into the groove 53 by the cross wire carrier 4. The arrangement of grooves described in the head of the die 3 is such that the groove 53 for the .cross wire permits the same to be carried in a plane below the line wire, but above the plane of the grooves 54 for guiding the legs of the staples into clinched engagement with the cross wire, thereby insuring the up-setting or clinching of the legs of the staples about the cross wires while the web or bight of the cable straddles the line wire.

'llhe general operation of the fabricating machine is substantially as follows rlhe main or line wires W which are rela- .tively heavy gauge are fed into the fabricating unit A intermittently by the reciprocab ing feeding device B, and are prevented from being withdrawn by means of the check device D. rllhis feeding-in of the main or line wires takes place while the jaws 5 and 6 are retracted, and consequently while the stapling plunger 2 is elevated above the anvil die 3, When the stapling plunger 2 is elevated to the proper point the staple receiving seat 46 thereof registers with the end of the section 37 of the staple carrier 1 in such a way thatthe leading staple Moenia thereon slides into the seat 46, and then as the stapling plunger 2 begins to move downwardly the shoulders 42 on the plunger engage with the ,inclined shoulders 41 on the carrier to push the carrier back out of the way, thereby entirely freeing the leading staple from the carrier and carrying it in the Seat 46. As the plunger 2 continues to move down, the spring legs 43 are forced together by the compression heads 4 to thus push the staple in the seat 46 and prevent its falling out during the continued downward movement. e

ln the meantime, when the lower end of the plunger 2 passes the upper end of the die 3 carried by the lower jaw 6 the cross wire carrier 4 delivers one of the cross wires W over the inclined edge l55 of the die 3, across the top of the groove 52,and into the cross wire receiving groove 53. Because of the overlapped relation of the plunger 2 and thevdie 3 the cross wire ll] will be safely positioned in the groove 53, and when the plunger reaches the limit of its downward movement the die 3 will move upwardly toward the line wire and the clinching grooves 54 will bend lower ends of the Staples legs about the cross wire W. rll`hus when the staple is fully curled about the cross wire W as shown in Figure 4, the said cross wire is united with the main or line wire W in a thoroughly practical and secure manner. When the joint thus formed is completed the jaws 5 and 6 recede carrying therewith the plunger 2 and anvil die 3, until the plunger die and anvil die reach the limit of their backward strokes, whereupon the anvil die 3 will be ready for the next operation to receive the cross wire `W, while the plunger die 2 will permit the staple carrier l to slide forwardly again to enable the leading staple on the section 37 to be placed in position to gravitate into the staple receiving seat 46, in the manner already explained. As the staple carrier l is adapted to carry an adequate supply of staples on the bar 36 the quantity of staples will always be sufficient to meet the demands of the fabricating operation.

llfhile any suitable and convenient form ofmachine may be used for .making and feeding the cross wires to the fabricating unit, the type of cross wire supplying device C 'shown in Figures l and 10 of the drawings may be conveniently utilized. rllhis device includes in its organization a suitable frame 56 having mounted thereon the wire cutting and straightening device 57. These devices may be of a standard commercial type obtainable .on the open market, and no claim thereto is made in the present case, the same being simply illustrated in more or less diagrammatic form and only to illustrate one way of making and straightening the cross wires for delivery-onto the ini clined conveyor tables 58 which may consist of a plurality of spaced inclined inverted T- rails or equivalent bars. As will be observed from Figure 1, the said inverted T-bars which constitute the conveyor tables 58 incline toward each other and have arranged therebetween a check and alining partition 59, the same being provided with the alining recesses or grooves 60 in opposite sides thereof and having a segregating gate or head portion 61 projecting qinto the delivery throatl 62 of the magazine chute 63. The described arrangement of the check partition 59 has the advantage of arresting or,

checking the cut lengths of cross wire at the end of their descent down the inclined feeding tables, and causes the same to straighten or Aaline with the runway or passage of the delivery chute 63, thereby preventing jamming or clogging of the wires at the entrance of the chute and permitting them to be stacked in single order therein, as shown in Figure 10.

From the delivery chute 63 the wires are removed individually by means of a delivery roll 64, the same having a plurality of spaced longitudinal grooves or pockets 6 5 formed in'its circumference for registering at intervals during the cycle of rotation thereof with the end of the delivery chute 63 to receive a single cross wire and carry it through an arc of substantially 180 for deposit on the upper flight of the horizontally disposed conveyor 66. rlhe periphery of the delivery roll 64 has a relatively snug fit with the hood or casing 64, thereby to insure the cross wires W remaining in the pockets 65 during the ,rotation of the roll from the point where it receives the wire, to the point where it discharges onto the conveyor 66, and, to insure that the wires will not shift longitudinally out of the pockets 65 before the proper time for delivery a suitable end guard 67 may be employed. 0n

the other hand, to compel delivery at the proper point a stripper blade 68 may be arranged at such a point that its stripping edge 69 will intersect the circumferential plane of the roll 64 and extend inwardly to a sufficient point as at 70 to reach behind the position occupied by one of the cross wires W in one of the pockets and forcibly eject the same as it is brought around to discharging position.

lAfter the cross wires are deposited in single order on the upper Hight of the horizontal conveyor 66, they are advanced to a y, point where they are picked up' by the carrier strip 71 of the upwardlyinclining conveyor 72,- and this conveyor, in turn, feeds the wires in single order to the delivery conveyor 7 3 which -deposits the cross wires on the cradle projections 31 vof the cross wire carrier 4. As( will also be observed from Figure lthe conveyors 66, 72 and 73 may the' pulley 94 of the conveyor 83.

tion 74 which passes over the pulley 75 of the main driving unit 23 and a pulley 76 on one of the conveyorsupporting shafts 77. The delivery roll 64 may also derive its power from the conveyor 66 by the chain or equivalent connection 78.

From the foregoing it will be apparent that the arrangement described provides simple and practical means for maintaining an adequate supply of pre-cut and pre-straightened cross wires for delivery to the fabricating unit A. However, by way of illustrating the range of modification that may be resorted to-in the construction of the cross wire supplying unit to obtain increased capacity therefor, reference may be made to Figure 12 of the drawings, wherein it will be observed that the type of cross wire supplying unit C' shown in that ligure consists of a battery of cutting and straightening machines 8O arranged at the top of a magazine column 81 having therein a vertical magazine chute V82 which provides materially increased storage capacity for the pre-cut and pre-straightened wires. This magazine chute 82 corresponds in function to the chute 63 in the device C and the 'wires are individually removed therefrom by thedelivery roll 83 which may be provided with the guard and stripper elements 84 and 85 to insure the delivery wires in single order to the horizontal receiving belt or apron 83a. In this form of embodiment the roll 84 may be driven by the gear 86 which meshes with a shiftable clutch pinion 87 slidably carried by an operating shaft 88 and adapted to be thrown into and out of engagement with the gear 86 through the medium of the clutch lever 89. When it is desired to use only one unit, the clutches-of all of the remaining units may be opened or thrown out, thereby permitting all except one unit to idle, or on the other hand when an increased capacity is desired all of the clutches may be thrown in thereby -causing all of the' units -to operate and provide an augmented number of cross wires for delivery to the fabricating mechanism.

The operating shaft 884 may carryat one end thereof a driving gear 90 adapted to mesh with a driving pinion 91 actuated by the pulley and belt connection 92-93 from pulley 94 may be .driven by belt or chain 95, and the cross wires supplied to the upper flight of the belt 83*1 may be picked up by ythe upwardly traveling Hight of the conveyor 96 to be fed to the delivery conveyor 7 3a which performs the same functlon with respect to the cross wire carrier ,4 that the This conveyor 73 doesjin the construction shown, i

in Figure 1.

12, wherein each of the cross Wire The multiple unit embodiment of Figure i and cutting units is individually controlled enables the operator to meet any requirements as to speed of fabrication, supplying a few, or as many cross wire lengths as the particular operation calls for.

Without further description itis thought that the features and advantages of the present improvement will be readily apparent, and it will of course be understood by those skilled in the art, that changes in the form, proportion, and minor details of construction may be resorted to, without departing from the spirit of the invention, or scope of the appended claims.
