(Cl. 140-112) 1 Referring to Figs. 1, 2, and 3 of the drawings, This invention relates to apparatus for making the machine has a pair of end frames I and 2 that are rigidly connected in front by a long hori zontal plate 3 provided on top with a clove tail general type shown in Perry Patent No. 813,823. The Perry patent shows a fence making ma 6 rib 4. The end frames are connected centrally by horizontal beams 5 and 6. The tops of the end chine in which a plurality of parallel vertical frames support a rotatable horizontal shaft ‘I strand wires are intermittently fed upwardly on which a plurality of grooved wheels 8 are through the machine while a single horizontal. rigidly mounted. These wheels are provided with cross wire is intermittently fed across the strand wires. The cross wire is cut periodically at one IO radial lugs 9 (Fig. 2) spaced apart the same dis tance as the stay wires of the fence being made end of the machine to form a stay wire that is by this machine. Parallel strand wires II] are led then transferred sideways into contact with the from’ coils rotatably mounted in front of the ma strand wires to which it is welded while the cross chine to grooved guide rollers journaled in the wire is again fed across the machine. The strand lower front part of the machine. These coils and wires then move upwardly a distance correspond» rollers, which are of conventional form and well ing to the desired distance between the stav known, are not shown. The wires pass under the wires, following which the next stay wire is welded guide rollers and then straight up through, the to the strand wires in the same way as the previ machine to wheels 8 over which they travel before ous stay wire. This machine is used extensively passing down to a reel I I journaled in brackets I2 for making welded wire fence, but it has the dis projecting from the back of the end frames. advantage that only one stay wire at a time can As shown in Fig. 2, the machine is driven by a be welded to the strand wires. The rate of pro ‘belt I3 that extends around a pulley I4 sup duction of the Perry machine can not be increased ported by bracket I2 at the left end of the ma by merely doubling the number of cross wires chine. This pulley carries a pinion It which 25 and they mechanism that handles them, because welded wire fabric, hereinafter referred to as fence, and more particularly to a machine of the meshes with another pinion I'I supported by the his stay wire transfer mechanism would then same bracket, and the second pinionv drives a interfere with feeding of the cross wires across the strand wires. - large gear I8 mounted on the projecting end of ‘ a horizontal shaft. I9 which is journaled in bear ings 2 I in the lower rear portions of the two end frames. One of the spokes of this large gear is provided with a radial slot 22 in which the lower end of a vertical rod 23 is slidable. The upper end of the rod is pivotally connected to the outer end of an arm 24 the inner end of which is oscil latably mounted on the end of top shaft ‘I. This arm is provided with a spring-presed pawl 26 for engaging a ratchet wheel 21 rigidly mounted on the top shaft. The ratchet wheel is prevented It is among the objects of this invention to pro vide a machine for making welded wire fence in which a plurality of stay wiresare simultaneously welded to strand wires, in which new stay wires are formed as the preceding set is being welded to the strand wires, in which several stay wires can be formed and Welded to the strand wires , substantially as quickly as a single stay wire, " and in which fence can be produced at a mate rially faster rate than heretofore. The preferred embodiment of the invention is illustrated in the accompanying drawings in from rotating in a reverse direction by a spring pressed dog 28 pivotally supported byv the adja» which Fig. 1 is a front view of our machine with the strand wire guide rollers omitted; Fig. 2 is a view of the left end of the machine; Fig. 3 is an enlarged fragmentary view of the right end; Fig. 4 is a still further enlarged fragmentary horizontal section taken on the line IV-—IV of Fig. 3; Fig. 5 is an enlarged fragmentaryv rear view of one of the picker ?ngers and the support ing bar; Figs. 6, '7, and 8 are fragmentary ver tical sections all taken on the-line A—A of Fig. 1 :45 but showing the stay wire transfer mechanism in ' three different positions; Fig. 9 is a fragmentary vertical section taken on the line IX—IX of Fig. 1; and Fig. 10 is a front view of the apparatus shown in Fig. 9. V ' cent end frame. It will 'be seen that every time gear I8 makes a complete revolution, it oscillates arm 24 and thereby rotates the top shaft a few degrees to feed the strand wires ahead the neces sary distance. The top shaft also projects beyond the right hand end frame 2, and its projecting end hasv a ratchet wheel 30 rigidly mounted thereon, as shown in Fig. 3. Encircling this wheel» is a loose pulley 3I that carries a spring-pressed pawl 32 which is engaged by the teeth of ratchet wheel 3% so that the pulley is turned by the wheel every time the top shaft is turned. “Pulley 3| is con as nectedby a belt 33.to another pulley 34 (Fig. 1) 3 2,405,257 rigidly mounted on the end of reel 1 l at the back of the machine, whereby to drive the reel in order to wind thereon the fence that is made in this machine. In order to produce the stay wires for the fence, a pair of verticallyspaced horizontal cross wires are fed across the machine from left to right inthe following manner. As shown in Fig. 2, the large gear [8 is operatively connected through bevel 4 pressing down on top of the bar. One side of the cutter frame is provided with an opening into one side of its vertical passage, and the bar is pro vided with a transverse slot 78 beside that open ing. Projecting into this slot is the lower end of a, bell crank lever 19 that is pivotally supported .byjthe cutter frame. The upper end of this lever is pivotally connected to the inner end of a link 8] that has its outer end pivotally connected to gears 36 and 31 to the rear end of a horizontal 10 the upper front end of an actuating lever 82, as shaft 38 journaled in the lower part of end frame ' shown in Figs. 1 and 2. The central portion of l. Rigidly mounted on the front end of this shaft lever 82 is pivotally mounted on the outside of end frame I, and its lower end rides against the All is pivotally mounted. One end vof this pawl inner face of big gear Ill which is provided with normally is urged by a spring into engagement 15 a boss 83 for-periodically swinging the lower end with a ratchet wheel 4| rotatably mounted on of the lever toward the end frame.

These guides are mounted on the rear sides hearing. The upper end of shaft 54 is journaled of a pair of parallel cross bars 90- and 9| sup in a bearing 59 supported by a horizontal I-beam ported at their opposite ends , by inverted L 51 the opposite ends of which are supported by shape :bars 92 the upper'front ends of which are end frame I and by the top of a vertical I-beam clamped to rib 4 of cross plate3. A vertically 58 resting on the machine foundation. spaced pair of these guide'members is disposed . Rigidly mountedon vertical shaft 54 is a pair 35 in front of each strand wire (Fig. 1). As shown is a short arm 39 on the outer end of which a pawl 7 of large grooved feed rolls 60 that substantially in Figs. 4 and 6, each guide includes a metal block engage a pair of smaller grooved feed rolls 6| in front of them.
