This invention :relatesto aimethod and-appa ratus for swaging and bendingzandam'oreparticularly to such amethod .andxapparatusxfor. fastening a sleeve assembled; on ..two stranded awi're structures to the wire structures .b swagingiand at the same time spreading .theiwireestructures at the point that they .leave Lthesleeve. .\The invention is of particulariutilityin.thepmanufacture of torpedo'nets such as disclosed'inimyicopending application, -.Serial No -5813310,;filed;;March .6, 1945. Prior tomy inventionawhenitiiwas desired to expand nets suchasdisclosed in my above identified application; sleevesrwere swaged .totthe wire structures which were. .thereafterirspreadsby separate means. The spreading-'- wasidoneibyxsecuring thefoot wire of1thenet andthenzapplying tension along the head wire'ito; spread theientire net at one time, by-partiaI tension spreading followed by individual setting at .each iintersection, or by individual SttilIg"iWi1'/h 'af ftWO iman power tool. ln all of-thesepract-ices; :the-in-con sistencies in set produced an openrneta structure having numerous areas which bagged; also caused variations in the width and length dimensions of the net. When thenetwastowedalong with a'moving ship, these bagged: areas causeda snaking motion through the .sea, thus increasing the resistance to movement-and decreasingwthe ships speed. 'In static use, the 'reversals of'fthe bagged areas caused by motionofthe water:further aggravated the strand .memberson'which the greatersuspension tensions ,hadbeenapplied, this causing fatigue failure and a shortanetlife.
It is an object of my invention-to; prov-ide..-a method of swagin sleevesto two stranded :wire structures and at the same time spreading:the wire structures to produce an open structure having uniform dimensions.
Another object is to provide apparatus .for 13311- rying out the above describedmethod;

:Hhefaapparatus'ofmy"invention consists of a carriage. housing .20. mounted n wheelsk22-for movement alongztrackslfl. Mounted in the, hous- :ing (20 are 2 two; parallellshafts :25 and 28. 'IKGYGd 'tcit-herfront. end: of :.these shafts are-like cam '50 shaped swagingrollmsrfifi havin p l l grooves .32 which together -form..an aperture .islightly: smaller. than '1 the ioutside contour. of t the :sleeves :4 .1. lfhelshaftsjz 6 .andz28; are'rotat'ed inopsposite directions inJbearings-M by means ofgearing 36 which is driven by means ofan electric motor 38. The shaft 26 is hollow and passing therethrough is a rod 40 having -a three-way positioned wing latch 42 Secured to its front end which operates a reversing switch 43 mounted beyond the gearing 3E5. Attached to the right side of the housing 29, as shown in Figure 1, is a bracket as on which is mounted a spreader cam 46 in line with the grooves 32. This cam is adjustable in a horizontal direction to and from the rolls 3% in order to compensate for different lengths of sleeves 4. A bracket 23 is mounted on the other side of the housing 20 and is pro-' vided with slides 59) for slidably receiving a sup port 52 which supports a second spreader cam 54. This cam is also adjustable horizontally tovand from the rolls 30 by means of a screw 56. A hydraulic cylinder 58 has it piston rod attached to the support 52 for moving it transversely of.
the roll pass.
In operation, the unspread torpedo net is suspended just in front of the swaging rolls with the sleeves 4 arranged in a horizontal position and the line ofsleeves approximately in the same horizontal plane as a point between the rollers. In this suspension the weave of the net is spread slightly by its own weight and flexibility. With the stranded wires 2 and the rolls to in approximately the position shown in Figure 4 and the machine stopped, the net intersection-is pushed into line with the grooves 32 with one strand carried over and one under the spreader cam 46 as shown. Cam 54 is in its retracted position. The wing latch 42 is turned in the direction which causes the motor 38 to drive the swaging rolls in the direction of the arrows in Figure 4. I his swages the sleeve 4 to the stranded wire structure, that is the sleeve metal flows into the interstices of the wire structure to develop a nonslip grip connection. During the swaging operation, the sleeve 4 is forced to the right as shown in Figure 4 and forces the wire structures 2 against the spreader cam 28 to bend them sufiiciently to give them a permanent set at approximately the point that'they leave the sleeve. The wing latch '32 is turned to the stop position when the rolls reach a position where any further power applied would result in slippage between slip clip 4 and the grooves 32, this being the position shown in Figure 5. If a longer sleeve than that shown is being swaged, the cam 46 is moved away from the rolls 3!! and if a shorter sleeve is used the cam is moved toward the rolls; With the machine stopped, the spreader cam 54 is moved out in line with the grooves 32 with one strand being carried over and one under the cam 54. The wing latch 42 is turned to its reverse position and the sleeve is moved to the left as shown in Figure 6 to force the wire structures at that end of the sleeve against the spreader cam 54 to bend them sufiiciently to give them a permanent set. The wing latch is turned to its stop position after the grooves'32 are suflicientlyclear of the sleeve 4 and strands 2 to permit their withdrawal from between the rolls. If the net is suspended from a point several feet above the swaging rolls, there will be sufficient flexibility in the net to swage five or more intersections in a vertical row before advancing the machine to the next position along the rails 24. The operation is then repeated in the new position.
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.
