This construction was hea-vy, costly, and wasteful ofmaterial.
An object of my invention isto provideamethod of-making a'torpedo net.
This and other objects will be :mcre :apparent afterreferring to the followingwspeoifieatiomand attached drawings, in which:

Referring more particularlytothedrawingssit will be seen that-the :net consists of a plurality of stranded wire structures which aret-bentzin zigzag arrangement in side .by :side relationship, the apices: of the adjacent zwire: structures iceing connected by double barrel: connectors 4 'whienare preferably of the typedisclosedsin-mys-copending application, Serial No. 563,286,.filediNovemberlB, 1944, and entitled Method and means 'forx-secuning fittings to wire structures.

Further details ar-id other modifications of the sleeve are xlisclosedLin my above :mentioned application. It will be seen that alternate sleeves. on eachvwiretstructurerare connected to-the wire structures :on opposite sides thereof.

Sincet-he sleeves 4;on:0.n stranded structure are connected. to the stranded structure'on reachaside thereof it' is necess My tha the-sleevesv he :passedprogressively over adjacent wire structures, aandythisiisapreferably done, from the :center of the-strand outwardlynto each end thereof. In otherwords, asshoWn-in Figure :5, a sleeverA isafirst-placedz over the firsttmms aml and ,jmoved :to the ;center thereof, :and ca :second sleeve 1B is passed ov.er the ;third and .fourth strands :and moved .to athe renter thereof. .From each-eni'da sleeve Sis thengpassedjover the second and f third -wire structures, and ;a ,sleeve D over the-first'and second wire structures. .A sleeve E is then-passed over the third pairofwire structures and :moved :to the :@center .atherreof .and a sleeve sistpassedmrogressively.from eachrend over .theiourthand fifth wire strueturesthei third and fourth-wirestructur,es,;the second and third wire structures, @and; first and second -wire structures, these heing rsleeves F, G, I-I,1and;l,;resp ectiveiy. Thisnperationisl -continued ,until the. sleevesrhave been placed over the :first and second :wires :10! therfulliwidthof the net; the sleevesbeing added in alphabeticalorder :asshown .in Figure 35. :At
this time, *itwill She-apparent that the. sleeves :will beplaced on thewirestructures-on table: |;8 within the trianglegindicated'sby the dash-dot .linesr30, v32;:the :base .of thetriang-le being-formed by the wire structureilocated at :34.

erators will be too close together on one side of the table. Additional stranded structures are then added on the assembly end of the net, and sleeves are progressively added from the base of the triangle to the apex thereof along lines 30 and 22 and pinned to the stranded structures on these lines. The operation may be performed continuously by pulling the assembled net along the table and adding wire structures at the charging end of the table as the net is pulled away from that end. After suificient net has been assembled to pass from the table l8 over the roll 25, the roll will pull the net along the table l8. From the roll 26 the net passes downwardly around a sec: ond roll 36. Between the rolls 26 and 36 the sleeves 4 are swaged to the wire structures 2 and the net is spread by bending the stranded structures to beyond their elastic limit as they leave the sleeves 4. This is preferably done by means of a plurality of swaging devices 38 mounted on a track to provide horizontal traverse for the full width of the net. Due to the weight of the net, the stranded structures 2 will separate somewhat so that the sleeves 4 may be swaged to the wire structures by means of swaging rolls 4b which are keyed to shafts 42 and which may be rotated in either direction by any suitable means. The swaging rolls have parallel grooves 44, which together form an aperture slightly smaller than the outside contour of the sleeves 4.
Movement of the net assembly over the rollers 26 and 36 is stopped and the net secured with a row of sleeves 4 in horizontal alignment with the swaging rolls 46. Rotation of the swaging rolls is stopped so as to provide entry of the two strands just to the right of the sleeve. Power is then applied to the rolls to rotate them in the direction of the arrows in Figure 6 and as the grooves come around the sleeve 4 is fed therebetween. The pressure exerted on the periphery of the sleeve causes cold fiow of the metal within the holes on into the interstices of the strand to bring about a fast connection. This method of fastening the sleeve on the wire structures is explained in detail in my above identified application, The net is preferably spread at this point by bending the stranded structures beyond their elastic limit as they leave the sleeves 4. This may be done by providing a spreader cam 45 atthe inlet and exit sides of the rolls 4 only one of which operates at a time. When using this means of spreading the strands, the right hand spreader cam is drawn out inline with the roll grooves, as shown in Figure 6, and the left hand spreader cam is pushed back out of line into inoperative position. Rotation of the rolls is stopped in the manner described above so as to provide entry of the two strands just to the right of sleeve 4. The top strand is carried over the top and the bottom strand under the bottom of the right hand spreader cam 46. Power is applied to the rolls to rotate them in the direction of the arrows shown in Figure 6 to swage the sleeve 4 on the wire structures 2. In the power driven travel of the sleeves the two strands are form bent, as shown, to take a desired permanent spread. Power is cut off while the sleeve is still within the grooves 44 and-the left hand spreader cam is brought out into line with the grooves and the top strand brought over and the bottom strand under the spreader cam. Power is reversed and the strands leaving the left hand end of sleeve 4 are form bent to take a permanent spread similar to the strands leaving the right hand end. The rolls 40 are then turned to a point where the swaged sleeve been be withdrawn and the machine is advanced toward the right to carry out a like cycle on the next sleeve. All three swaging machines 38 may be operated at the same time. The completed net is cut to the desired length after leaving the roll 35, and if boundary ropes !4 are used they may be added at this time.
While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
I claim:
1. The method of making a zigzag weave net which comprises placing a plurality of stranded wire structures of a length substantially equal to the width of the unspread net side by side in substantially parallel relationship, progressively passing double barreled sleeves over adjacent stranded structures from the center outwardly to each end thereof, spacing the sleeves at the desired position along the stranded structures to obtain the desired openings in the finished net, thereafter applying sufiicient pressure to the sleeves to secure them to the stranded structures, and spreading the net by putting a permanent bend in structures in the plane of the net at the point where they leave the sleeves.
2. The method of making a zigzag weave net which comprises placin a plurality of stranded wire structures of a length substantially equal to the width of the unspread net side by side in substantially parallel relationship, progressively passing double barreled sleeves over adjacent stranded structures from the center outwardly to each end thereof, spacing the sleeves at the desired position along the stranded structures to obtain the desired openings in the finished net, thereafter applying sufiicient pressure to the sleeves to secure them to the stranded structures, and at the same time spreading the net by bending the stranded structures beyond their elastic limit in the plane of the net at the point where they leave the sleeves.
3. The continuous method of making a zigzag weave net which comprises placing a plurality of stranded wire structures of a length substantially equal to the width of the unspread net side by side in substantially parallel relationship, progressively passing double barreled sleeves over adjacent stranded structures from the center outwardly to each end thereof, spacing the sleeves at the desired position along the stranded structures to obtain the desired openings in the finished net, adding additional stranded structures at the unassembled end of the net, and then repeating the above steps.
4. The continuous method of making a zigzag weave net which comprises placing a plurality of stranded wire structures of a length substantially equal to the width of the unspread net side by side in substantially parallel relationship, progressively passing double barreled sleeves over adjacent stranded'structures from the center'outwardly to each end thereof, spacing the sleeves at the desired position along the stranded structures to obtain the desired openings in the finished net, repeating the above steps, applying sufiicient pressure to the sleeves to secure them to the stranded structures, and spreading the not by bending the stranded structures beyond their elastic limit in the plane of the net at the point where they leave the sleeves.
5. The method of making a zigzag weave net which comprises placing a plurality of stranded stranded structures from at least one end of the stranded structures, arranging the double barreled sleeves on said stranded wire structures so that adjacent sleeves along the length of the stranded structures will have only one common stranded structure therethrough, the other stranded struc- 10 tures in the plane of the net at the point where.
