11 Claims. '(01.114-241i This invention `relates to` an improved` sub-` marine net. A y y Oneof the main objects' of the invention is to provide a net of this character which may be collapsed inaccordion-like `fashion for facilitatingstorage in acompact form, convenience in handling during Vshipment and particularly during laying operations.` l l y l Another object of the invention is the provision of anet of this kind which can be built to desired length from attachable and'detachable sections eachcornprising a `oor'nplete'unitf` A further object of `theinvention is the Drovisionof net sections of this character which can be Wound upon a reel,` as is a hose. in either separate or connected condition and paid olf sel during layingoperations.
A still furtherobject ofthe invention is the provision of means for connecting net sections of this kind together and to a common float line which accommodates separation of each section from the others and, from the float line under the strain applied when a section of the net is engaged by a submarine.
Additional objects of the invention are to prolfrom the reel while the latt"`er is carried by a vvesvide `net sectonswhich` arebuilt up ofrelatively short lengths of flexible materialfsuch `as Wire, arranged in `frame-like units and having eyes on their extremities loosely pivotally connected together by rings which accommodate substantially free weavingl and Working of successively adjacent `portions of the net sections under wave moval of the wrapper and which are released by the action of water thereon in order to guard against complete expansionlof an initially layed section of the net prior to immersion of the entire section. y M
`A still further object of the invention is to provide on a net of` this kind bombs and/or signal devices which are constructed to be exploded or actuated respectively upon contact with a submarine. i

Each net section comprises" a pluralityof horizontally extending rows of wire bars` I 2 and aplurality of vertically extending rows of wire bars I3 located at the junctions ofthe bars I2 of the horizontal rows. The wire bars I2 and I3preferably comprise high carbon steel Wire having a high" tensile strength of the. order of 300,000 pounds `per square inch. These bars are flexibly connected together atltheir adjacent `end portions byrings I4.` `Each end of each bar is attached to a ring I4 in any suitable manner which will permit lim-l ited pivotal andshifting movement of the end of the bar `with respect to thering I4. As illustrated in Fig. 4, the endportion of each wire bar is preferablywrappedtwice about the ring and then several times about the standingfpart of the bar, thus forming a secure connection which is characterized by the required `flexibility.
j Extending along the uppermost horizontal row of bars I2 is a noat line generally designated by thenmneral I5 whichcomprses a rope .or cable An` illustrative embodiment of the inventioniis` the longitudinal extremities of the net sections' A and B are provided with connecting link mem-1 bers which include relatively .shrterwire bars, 20. A wire bar is flexibly connected ,to veach of the rings ofthe row of bars at each longitudinal extremity of the net in the manner described above and illustrated in Eig. L /A ring2l is preferably flexibly connected in a similar manner to the opposite end of each wire bar 2Uf The' rings;V 2 I. i are. detachablyi connected together. `by .an S-shaped parting.- .clip. 22-,which; like. thepar-ting links I.9',.=is.f.adapted. to openwhen subjected ,to af predetermined straiinsin` order ,ftop,ermit separation of` one netmsectionz from another..
