(54) MARINE LIFE TRAPS (71) 1., WARREN HUBERT KINSER, a Citizen of the United States of America, of F/V Ebb Tide, Kodiak Boat Harbor, Box 1726, Kodiak, Alaska, United States of America, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly des cribed in and by the following statement: This invention relates generally to marine life traps as used for catching various species of marine life.

Known traps for catching various species of marine life have a number of disadvant ages. One problem with known devices is that the traps have relatively large obstruc tions in the path of the desired species which deters same from being caught in the trap and their fixed entrances also offer escape routes.

Another problem with known type traps is that they are basically of rigid construc tion and as such take up quite a volume of space. This is especially undesirable aboard the average fishing vessel where space is at a premium. Of known traps, in order to dis assemble, fasteners must be removed which structure is either unduly complicated, quite fragile, or after a short period of use be comes inoperable.

According to this invention a trap for marine life comprises a top closure means, a bottom closure means, guiding means connected between the top and bottom closure means, and side closure means guided by the guiding means and mounted for move ment between an open position in which the side of the trap is open and a closed posi tion in which the sides of the trap is closed, and means connected with the side closure -means for moving it to the closed position from a remote location.

The invention may be performed in vari ous ways and some specific embodiments will now be described by way of example with reference to the accompanying draw zings in which: Figure 1 is a perspective view of a marine life trap in use; Figure 2 is a vertical, sectional view of the trap shown in Figure 1 as in use in the net collapsed trapping position; Figure 3 is a vertical, cross-sectional view of the trap shown in Figure 1 in the closed position ready to be hauled aboard a fishing vessel; Figure 4 is a cross-sectional view, in part, taken generally along line 44 4 in Figure 3; Figure 5 is a detailed cross-sectional part of the lower left hand corner of Figure 4; Figure 6 is a perspective view of the lower portion of the trap shown in Figure 1 as in the marine life selection step; Figure 7 is a perspective view of another embodiment in the open, ready for trapping position; Figure 8 is a side elevational view, partly in cross section, of the trap embodiment of Figure 7; Figure 9 is a side elevational view of the embodiment of Figures 7 and 8 in the partially collapsed position; Figure 10 is a fragmentary top edge portion shown in elevation of the latching mechanism; Figure 11 is a perspective view of a one way latch pin and mount connection therefor; Figure 12 is a detailed perspective view of a pivot ring mount for foldable side guide rods; Figure 13 is a cross sectional view of retaining pin detail; Figure 14 is a perspective view of a chemical light per se; Figure 15 is ,a rope tie with attachment loop detail; Figure 16 is a guide rod pivot with locking sleeve; Figure 17 is a detailed showing of'the guide rod pivot joint; Figure 18 is a detailed showing of rope winding covering; Figure 19 is a detail of a removable guide rod upper and securing structure; Figure 20 is a detail of a removable guide rod lower end securing arrangement; Figure 21 is a side elevational view of a rigid trap embodiment; Figure 22 is a fragmentary perspective view of the frame elements per se of the rigid fish trap embodiment of Figure 21; Figure 23 is a perspective view of another embodiment of this invention; Figure 24 is a side elevational view, partly in cross section, taken generally along 24- 24 of Figure 23, Figure 25 is a side elevational view of a guide support rod, taken along 25-25 of Figure 23; Figure 26 is a side elevational view of another type guide support rod; Figure 27 is an enlarged detail of the lower end of the guide support rod of Figure 26; Figure 28 is an elevational view of a retaining pin latch mechanism; Figure 29 is a detail of a resilient catch strap connection; Figure 30 is a detail view of an upper cross rope double loop and terminal end eye ring structure; Figure 31 is a detail of a side net framework reinforced corner with rope guide eye structure; Figure 32 is a top plan view of double cross bars with insulating covering; Figure 33 is a perspective view of the side net strap and retention structure for the latch pin mechanism; and Figure 34 is a perspective view of the framework structure per se of this embodiment.

Referring to Figure 1 of the drawings, reference numeral 10 indicates a trap in the open position and as in use on the bottom of a fishing area. As shown, it is in its open or net collapsed position and is ready for entry of marine life to be caught. Figure 1 depicts a king crab approaching the trap probably to be caught therein. Normally appropriate bait for the type of marine life sought would be attached to the centre portion of the trap to lure the marine life into the trap. Such bait is not presently shown in the illustrations.

Looking at Figure 3, the five annular rings which form the basic operating structure of this trap can be seen in cross section. The top ring 12 has netting covering the inner area thereof, labelled 13, and in normal operation said ring will float in a horizontal position supported by floats 34 suitably attached to said ring by connecting means 35. The next annular ring 14 has the upper edge of a sleeve-type net 26 attached thereto, as at 28. The third or middle ring 16 has the bottom or other end of the sleeve net 26 attached at 30 thereto. These two rings 14 and 16 and the sleeve net 26 form the working portions of the trap.

A large elastic member or rubber band 32 encircles the outer circumference of the sleeve net 26 at approximately the middle thereof as best seen in Figures 3 and 4. This rubber band 32 is under tension on the sleeve net so that when the upper ring 14 is allowed to drop, the rubber band 32 will cause the net to collapse as best seen in Figures 1 and 2. Thus, as can be can be visualized, the tension applied by the rubber band will keep the sleeve net 26 from be coming a large tangle of loose webbing, moving in the currents, that experience has shown certain commercial marine life will not enter, and allow it to be collapsed and extended at the will of the fishermen operating the net in an orderly fashion.

The bottom portion of the trap, depicted by itself in Figure 6, consists of a fourth annular ring 18 appropriately covered in the centre area thereof by netting 19 and reinforced by cross bars 21. Said fourth ring and net thereon are normally attached to the trap adjacent to the third ring 16 for complet ing the trap enclosure. As can be seen in Figure 3 the upper ring 12 has netting to enclose the upper part of the trap, the sleeve net is extended to enclose the sides of the trap and the bottom ring 18 is attached to ring 16 to enclose the bottom of the trap, In order to prevent the netting 19 of the lower ring structure from becoming embedded in the bottom surface of the fishing area or being damaged by roeks or other objects on the bottom, the ring 18 is attached to ring 16 to enclose the bottom of the trap. In order to prevent the netting 19 of the lower ring structure from becoming embedded in the bottom surface of the fishing area or being damaged by rocks or other objects on the bottom, the ring 18 is mounted on a support structure comprising a fifth ring 20 and short supports 22 of approximately one to five inches in height. The fifth and bottom ring 20 is open without any netting whatsoever and acts as supporting structure for the fourth ring 18 which is actually the ring which supports netting 19 to complete the bottom of the trap. When fishing for a species that prefers a lower entrance, the fifth ring may be omitted.

As mentioned previously, the top or up permost ring 12 floats horizontally in the water suspended from float balls 34. The height this ring floats from the bottom rings of the trap is determined by rope members 40. These members 40 of appropriate length are braided rope or lines that flatten when pressed. They are attached at one end by a non-loosening, easily untied knot to the top ring 12 and the lower end of said ropes are appropriately tied with similar knots to ring 16, as best seen in Figures 4 and 5. Such knot 50 is shown in these Figures for securing the rope 40 to the ring 16. Said ropes 40 are of sufficient length to leave an additional end portion 41 extending from the knot50 after the rings 12 and 16 are connected by the ropes 40. As seen in Figure 5, this end portion 41 can be looped around the fourth ring 18 and, as seen in Figure 4, securely tied thereto by another knot 52 to finnly attach rings 16 and 18 together.

Figures 2, 3 and 4 of the drawings all show the use of two knots 50, 52 for lines 40 to hold rings 16 and 18 together. This of course causes a small gap to be present between said rings, as shown. When fishing for small species of marine life, such as shrimp, this gap may be very undesiråble.

To eliminate the gap between rings 16 and 18 a single knot, not shown, may be used to tie both rings close together instead of the two knots. This embodiment is intended to be included in this invention.

In normal operation, rings 16 and 18 will be attached together as shown. This attachment of the rings 16 and .18 together by means of the rope and tie means which comprise another feature. As can be readily visualized, once the trap is closed, as in Figure 3, and the over-all trap raised to the surface and brought aboard a fishing vessel, it is a very simple matter to loosen all of the knots 52 and thereby permit the bottom net 19 and the rings 18 and 20 to rest on the deck of the vessel. The upper rings and netting thereon can then be lifted away from the bottom net 19 leaving the marine life caught therein easily accessible by the crew for selection of the wanted species and discard of the unwanted ones. Furthermore, if all of the catch is to be kept and dumped into the hold of the vessel, this also is easily accomplished by merely loosening two or three of the knots 52 and allowng the lower portion of the trap to open at these points about the hinge point formed by the remaining tie or ties. Thus, the entire catch can be easily dumped into the hold without completely separating the bottom of the trap or without manipulating extra doors or openings as is usual in conventional type fish traps. Obviously with three of the four tie points shown loosened and only one tie point remaining as a hinge point, an exeremely large opening is provided at the bottom of th trap for complete easy discharge of the contents thereof When preparing to fish with this trap, it would nonnally be carried aboard the ship in the collapsed position, as can be visualized from looking at Figures 1 and 2, and once reaching the desired fishing site, the appropriate bait would be attached to the centre portion of the netting and cross rods 21 and the entire structure dumped overboard. The floats 34 will cause the device to sink in a horizontal position and said device will come to rest as depicted in Figure 1. Fish, king crabs, and other marine life then can easily enter the trap to get the bait without any obstructions other than the ropes 40 and 43 to encounter. The lines 43 are used to close the trap by raising the ring 14 and' operate in the following manner. These lines 43 are shown as passing over the outer surface of ring 12 and being retained by rings 15 welded to ring 12 at the desired positions for the lines 43. Normally four such lines are employed, but three lines may be used, or more, if desired.

Another embodiment of this inveintion is for the lines 43 to pass through rings or eyelets welded or attached to the inner circumference of ring 12, thus reducing the strain on lines 43 because of a slightly more direct pull when line 37 is lifted to raise the ring 14. The lines 43 are attached to a ring 41 which is connected to another rope or line 37, another ring 41, connecting means 39 and a primary float 36 which normally is on the surface 38 of the body of water being fished. This primary float 36 is the one the fishing vessel returns to after an appropriate waiting time to permit the trap to catch some marine life. Upon return td the trap, the crew will pull in line 37 which will put the lines 43 under tension and lift the ring 14 to extend sleeve net 26 and close the trap as depicted in Figures 3 and 4. The rubber band 32 is stretched to its outermost limit at this time. By further pulling of the line 37, the entire trap will be lifted off the bottom and can be raised to the surface and pulled onto the deck of the vessel.

Figures 7-20 illustrate another embodiment of the trap and as generally disclosed in Figures 1-6, a trap for catching marine life is perferably formed of a plurality of annular rings 112, 114, 116, 118 and 120. The top ring 112 and the next to the bottom ring 118 are provided with netting 113 and 119 across the open centre thereof. In this embodiment, the upper rings are of smaller diameter than the lower ones to allow a greater telescopic collapse of the overall trap for storage purposes and to provide a more gradual climb for some marine life and to provide a lower centre of gravity. The two members 112 and 118 basically provide the top and bottom portions of the trap, while the bottom ring 120, attached to the bottom covered ring 118 and mounted thereto by short stubs 122, keeps the bottom netting 119 a short distance above the surface bottom of the ocean, or other body of water which is being fished. The lower ring 118 may be provided with cross bars 121 much in the manner of the first embodiment. However, in this embodiment, pairs of cross bars 221 are provided at right angles to each other on the upper ring member 112 and above the netting therefor.

These cross bars may be attached by appropriate welding or the like to the ring 112.

Normally a rope loop 222 will be attached about the centre junction point of these cross bars for engagement with a hoist hook aboard the fishing vessel in order to lower the trap while in the erected but open for fish catching position, as in the view of Figure 7. Also attached to these cross bars may be lighting structure such as shown in Figure 14 which will be described in detail below.

In this embodiment of the invention, rings 114 and 116 are of slightly smaller diameter than ring 118 so that in the position as shown in Figure 7, the rings and associated side netting 126 will compress more completely in telescopic fashion to present a smaller obstruction to the marine life. Also, when the top ring 112 is lowered into engagement on top rings 114, 116 and 118 for the purpose of storage and transporting aboard the fishing vessel, a more compact package will be provided. The elastic member 132 made of rubberized nylon material or the like will effectively bring the side netting 126 inwardly toward the centre of the device while maintaining the netting in a relatively taut manner and prevent entanglement thereof. This can best be seen in the views of Figures 8 and 9.

The basic operation of the structure disclosed so far is that, after the open trap of Figures 7 and 8 has attracted a suitable amount of marine life, the fishing vessel will find the trap by means of the floating surface buoy 136 land pull on line 137 to in turn pull on loops of rope 143 and 1431 as connected to line 137 by double eye connector 141. Thus pulling line 137 will lift the 'ring 114, which is the upper ring having the side netting 126 therearound, which will then move upwardly until closely adjacent to top ring 112. In the device of Figures 1-6, it has been discovered in actual practice that if there are heavy seas when the fishing vessel is pulling the closed trap aboard, occasionally slack will occur in line 37 allowing lines 43 to drop and thus allow all or a portion of the ring 14 to drop away from the top of the trap. Thus, trapped marine life may escape through the gap created by this separation. In the device shown in Figs. 7 to 20, several structural features have been added to solve this problem. Additional side netting 226 and 228 is attached at appropriate points to the upper ring 112 and the central netting 113 supported thereby. Weighted rings 227 and 229 provide the necessary weight to the lower portion of these side nets to cause them to 'hang downwardly through gravity action.

With these additional side nets, even if separation should take place between the rings 112 and 114 when the trap is being hoisted aboard the fishing vessel, already trapped marine life cannot escape because latch pin 166 prevents ring 114 from falling below 229. The width of netting 228 and diameter of ring 229 enables ring 114 to contact ring 229 and move above latch pin 166 as illustrated in Figure 10.

Then when rope 137 slackens and ring 114 drops toward latch pin 166, the ring 229 and netting 228 follows it downwardly thus preventing escape of even small marine life.

Another problem discovered with the embodiment of the trap shown in Figs. 1 to 6 was that the top ring 14 for the side netting tended to move sideways relative to the axis of the rings 12 and 18. In the improved trap disclosed in Figs. 7 to 20, this is prevented by means of the vertical guide rods 140 and 142 which are provided on either side of the movable ring 114 on at least four equally spaced quadrants thereof.

One of the advantages of the fish trap shown in Figures 1-6 is in the rope con sections between the various ring structures which permits a substantially complete collapse of the trap abroad the fishing vessel for storage and transporting thereof. With rigid rods 140 and 142 as provided in the embodiment of Figs. 7 to 20, this important feature normally would be lost. However, the inner guide rods 140 are made to be removable while the outer guide rods 142 and 1421 are arranged to fold near the centre point thereof. This can best be seen in Figures 16 and 17 wherein a slidable telescopic tube 144 is provided to cover the pivotal joint 146 between the rods 142 and 1521.

Figure 17 shows the joint 146 in greater detail This pivot joint is arranged so that it can only pivot in the outward direction as shown in Figure 9 because of the bar member 148 which abuts the ends of rods 142 and 1421 which are connected by pivot pins 150 and 1501 to a pivot bar 1491. When the sleeve 144 is released by retracting or removing pin 145 so the sleeve can move downwardly to the position shown in Figure 9, then the rods 142 and 1421 may be folded outwardly as in Figure 9 to permit the top ring 112 to be collapsed upon the other rings therebelow. Figure 12 shows one type of pivotal mounting for top rod portion 1421 which consists of an eye 193 welded to the rod and encircling ring 112. This eye 193 is similar to an eye 194 for the bottom rod 142 which encircles the ring 116 as best seen in Figure 8 and their width is such that at least two rods will resist movement from any direction of current.

Figure 13 shows a removable retaining pin 145 which may be -provided with a pivotally mounted retention member 147 on the end opposite to the head thereof to retain said pin through appropriate apertures in the sleeve 144 and the upper rod 1421.

Figure 11 shows a removable latch pin used with the upper portion of pivotal rod 1421 for the purpose of positively latching and retaining the upper ring 114 for the side netting in the closed position of the trap once the ropes 143 and 1431 have been suitably actuated and lifted by the fishing vessel. One type of latch pin may consist of a square member 160 provided with a suitable aperture 161 at the outer end thereof for engaggement through a square aperture 162 within the rod 1421. A retaining pin 163 (similar to the one in Figure 13) is designed to mate with hole 161 to lock the member 160 removably in aperture 162. The other end of member 160 is provided with a portion 164 having pivotally mounted thereto by pivot pin 165 an extension 166. Spring means, not shown, normally is associated with the pivot point between .164 and 166 and around pivot pin 165 in order to normally keep the member 166 in a horizontal position as shown. However, when the ring 114 is lifted upwardly to close the side netting of the trap, one-way pin member 166 will permit passage of said ring 114 past member 166 and then will snap back to the horizontal to positively retain the ring 114 in the upper closed position. These oneway latch retaining pins 166 which 'are semiautomatic in operation, together with the side nettings 226 and 228 effectively prevent the escape of trapped marine life from within the trap once it has been closed by lifting the side netting 126 and prior to being brought aboard the fishing vessel. Other types of spring operated one-way latch pins may be used. In order to release the ring 114 and permit netting 126 to move to open position ,a spring biased release pin 1651 is mounted in underlying relation to pin 166 to normally keep pin 166 horizontal but enable the pins 166 to swing downwardly to release the ring 114 when all of the pins 1651 are pulled at a remote location.

Figure 12 also shows one of the guide eyes 172 for the lifting loop lines 143, 1431 appropriately formed and welded within the ring 112 so ;as to be protected and out of the way. A guide tube 170 is appropriately welded or otherwise fastened to either cross rods 221 or ring 112, or both, and provides the upper support and glide for removable guide rod 140. A removable pin 1451, similar to that already described in Figure 13, may also be used to retain the removable rod 140 as mounted. A lower guide tube sleeve 171, best seen in Figure 8, similar to that of upper tube sleeve 170 is provided and appropriately mounted from an extension 174 welded to ring 116. As can be readily visualized, the guide rods 140, and 142, 1421 when in the erect vertical arrangement as shown in Figures 7-10 will form a positive guide channel for movement of ring 114 therebetween and prevent the side movement of said ring and in turn the side netting 126.

When it comes time to collapse the trap upon the deck of the fishing vessel, pins 1451 the suitably removed from the at least four rigid guide rods 140 and the respective guide rods 140 removed from their tubular guide sleeves 1-70 and 171. After removal of the guide rods 140, then the folding rods 142, 1421 may be folded as already described. The trap at this point then will be completely collapsible into a very small compact package for transporting and/or storage.

Figure 15 shows a looped rope 180 tied around bottom cross brace 121 and the looped end 182 is wrapped li- times around rings 116 and 118. The loop 182 is used for attachment of the elastic strap 184 with hook 186 thereon for the purpose of maintaining appropriate tension on rope 180 to hold 116 and 118 together When hook 186 is removed and the trap suspended, the wraps unwind to release rings 116 and 118.

The chemical light 195 as shown in the perspective view of Figure 14 may be appropriately mounted to the double cross bars 221 by clamp structure 196 and as designed with double opposing reflectors 197 will provide light both toward the centre of the trap as well as upwardly away from the trap. Some species of marine life are attracted to light, while others are afraid of light and tend to move away from same. By energizing one portion or the other or both portions of the light of Figure 14, various species may be encouraged into the trap.

When the light is reflecting inside the trap, it will attract species that desire light. When the light is reflecting outwardly and the trap is dark, certain species will be attracted to the bait in the dark trap. Bait is suspended on line 190 between the top and bottom of the trap. The light of Figure 14 is preferably of the chemical type which requires no batteries or electrical source to openate. Such chemical lights are currently available in greenish yellow colour but different colours will be used for different depths of water and different species of marine life. In order to vary the colour of the light, reflective coloured strips are adhesively attached to the inner surface of the reflectors 197. The lamps 195 may be a single or multiple arrangement arranged in any desired location.

Another feature of this embodiment is in the rope ties 180 which hold the bottom ring 118 of the trap which has the central netting thereon removably to the lower ring 116 for the side netting. This feature as disclosed more fully in Figures 7 to 15 and permits either partial or complete release of the bottom trap ring 118 from the side netting ring 116 in order to either completely remove the upper rings from the lower one 118 to release the caught species of marine life thereon, or permits a partial hinge like opening, due to the one or two remaining ties' after the first couple of ties -have been untied, to permit a dumping of the caught species into the hold of the fishing vessel.

This- flexibility of release or dumping of the caught fish, crabs and the like, is one of the important features of this type of trap.

Figure 18 shows how various rings may be wound with rope binding to fill gaps between members to prevent escape of small species and to prevent the metal rings from direct contact with other. This is important from; the standpoint of elimination of noise as well as to decrease any electrolytic action between the metals used in the trap.

Figures 19 and 20 show the details of the tubular guide sleeves 170 and 171 for the vertical guide rods 140. The vertical guide rods 140 which are removable when it is desired to collapse the trap, have the lower end thereof fitting within the hollow lower tubular portion 171 which is supported by bar 174 attached by welding 175 to ring 116. The upper end of removable guide rod '140 is slidably retained within the hollow sleeve 170 by means of the removable pin 1451, described in greater detail with reference to Figure 13. These tubular guide 'sleeves 170, 171 function quite well, and the guide rods 140 provided at each of four points around the respective rings 112 and -116 permit a user of the device to quickly install same when it is desired to set the trap up in erected form ready to be lowered over the side of a fishing vessel and ready to start the trapping operation. They can just as easily and quickly be removed when the trap has been brought aboard the fishing vessel after a period of fishing therewith, and then the trap- may be completely collapsed in compact form for storage aboard the vessel.

Looking at Figures 21 and 22, a rigid embodiment of the fish trap of this invention will now be described with Figure 22 showing only those components which are rigidly attached. In these views, the plurality of rings which make up the end and side members of the trap together with the enclosure netting are all labeled with the same reference numerals as used in the embodi ment of Figures 7-20, but with a prime added thereto. In this embodiment, the re movable guide rod 140 has been replaced with fixed one 240, while the foldable guide rod 142, 1421 has been replaced with a single fixed one 242. These are appropriately welded by welding 1751 to the lower ring member 1161 ;and the upper ring member 1121. Suitable loop lines 243 connect to the movable ring 1141 in order to raise and lower the side netting as in the first em 'bodiment. Depending additional side nets 2261 and- 2281 are also provided as well as the latch pin arrangement 1661 similar td that of the embodiment of Figures 7-20.

This embodiment has all of the desirable features thereof as to the guiding, closure and -latching structure for the side netting rings, but is always in the fully erect large volume state and therefore does not have the desirable - features - of collapsibility for storage and transporting. However, such a trap will be better for a large boat that does not have a storage problem. ture in the outer guide rod 342 and a retaining pin 363 positively holds such a latch pin in mounted position. As best seen in Figure 33, a resilient strap 466 with a hook 468 may be used to retain the one-way latch pin 366 in the release position against the bias of the internal spring. An eye 368 suitably provided on the pin 366 completes the structure. The purpose of this latch hold to the release position structure is so that on deck the upper framework 314 for the side netting may be worked freely without being held or latched by the pin member 366.

Looking at Figure 34 again, tubular guide rod holding sleeves 370 may be seen on the top framework 312 while appropriate eyes 512, 527, 514 and 516 are provided with each of the associated square frameworks at the respective corners thereof for engagement with corner ropes 542, as best seen in Figure 24, for connecting the total trap framework together in a releasable manner.

These tie ropes 542 permit the various framework square to be appropriately adjusted relative to one another and are another important feature of this arrangement.

The square framework 314 is connected to the upper edge of side netting 326 while the framework 316 is connected to the lower edge of such side netting. Another resilient elastic net band 332 is provided at approximately the centre of this side netting to effectively cause the side netting to fold into compact position as best seen in Figure 24 when the device is opened for initial catching of marine life. Figure 23 also shows this trap in the open ready for use position with the side netting neatly folded into position. This presents very little in the way of obstructions to marine life.

Outer guide rods 342 fit into the tubular guide sleeves 370 on upper framework 312 and similarly fit into the lower tubular guide sleeves 371 mounted on the lower framework 316. In order to securely retain the trap in collapsed condition during storage, short rods (not shown), identical to rods 342 except shorter in length, replace rods 342 and are secured in sleeves 370 and 371 in the same manner (see Figure 25). The length of the short rods is determined by the distance between the outer ends of sleeves 370 and 371 when the trap is collapsed.

Again, this lower framework 316 is appropriately tied to the framework 318 which has the cover netting across the centre thereof for forming the bottom of said trap. Appropriate cross members 321 brace and structurally strengthen this bottom framework. Small supporting studs 322 may be provided for attaching the bottom of the trap to a lower square framework 320 which is the framework member which directly engages with the bottom surface of the body of water which is being fished. This bottom member may be left off in some models of this device and the bottom of the trap, i.e.

framework 318 with central netting thereon, may rest directly on the bottom of the water.

As best seen in Figure 31, the weight ring 327 for the side netting 426 has the corners appropriately built up by additional strap material 427 welded thereto. Thus, the rod member 327 which is of slightly smaller outer size than framework 312 is built up by this additional portion 427 so that ring 314 can close without binding on rope 542.

Figure 24 also shows the leftrnost corner tie rope 542 as tied at the top, looped about the side skirt ring 327 and then wrapped around rings 316 and 318 and held tight by strap 384. This tie line 542 may also be seen in Figure 29 which also best shows the loop 544 which is formed by the end of said line for attachment to hook 386.

Inner guide rods which are removable are also provided at the respective corners of the framework. These inner removable rods 340 are appropriately supported by a lower pin structure 471 mounted on a bracket 474 appropriately welded to framework 316.

Figures 26 and 27 best show this mounting and holding structure for the lower end of the guide rods 340. While a pin 471 is provided for reception within the aperture 441 on the lower end of guide rod 340, a reverse structure similar to that of Figure 20 may be substituted. The upper ends of the inner guide rods 340 are suitably held and guided by the tubular sleeves 470 which are appropriately welded inside of the corners of square framework 312. In the embodiments shown these tubular guide sleeves are also welded to the cross rods 521 for additional strength and rigidity. A removable pin 345 similar to 145 already described in the previous embodiments also is used to retain each of the respective inner guide rods 340 in their mounted position.

Figure 30 shows the double eye terminal end which is attached to line 137 or 437 of the various embodiments for assuring that the line loops 343 and 3431 will always be separated from each other and will not tend to interfere or entangle with each other.

Also, this double eye terminal end permits the two single loops 343 and 3431 to be connected to the appropriate corners of the raisable framework 314 and will be selfcentering in a semi-automatic nature as line 437 is lifted. That is, it has been discovered that when single lines are attached to a single connecting ring for line 437, there was a tendency to exert more force on one outer edge of the ralsable framework than the other and get a tilting of the side netting with a partial gap left at the opposite side thereof. This defect has been cured by the arrangement of the double loop lines 343 and 3431 together with the double eye ter minal end 341 as shown in Figure 30 insuring equal tension of ropes 343 and 343 regardless of conditions encountered.

Figure 32 shows the connection of the cross bar members 521 with the central guide channels 543 as appropriately welded and connected together being covered with a soft insulating coating 390 over the central area thereof. This covering will reduce any noise when current and seas move rope 437 and double eye terminal 441. The elongated shape of channel 543 is important since it permits ropes 343 and 3431 to have no bends. When this trap is stored, short rods replace the outer removable rods thus assuring that the trap remains intact. A rope loop 391 (Figure 24) is attached to the top braces for lifting- the trap.

While the latter embodiment has been shown as being of square nature, it may also be rectangular, elliptical, triangular, or various other common as well as uncommon shapes. Similarly, the other embodiments while shown in round shape, also may be square or any of the other configurations mentioned above. The important features are the top and bottom enclosures, the side enclosure structure which is movable from an open ready for trapping position to a closed after trapping position together with the additional side netting enclosure structure, as well as the guide channel structure of rigid, semi-rigid or completely collapsed form for assuring that the operating framework for the side netting will function in the manner intended. Also, in the semi-rigid and flexible versions of this invention, the device permits complete collapse thereof into a very small flat package for storage and transporting.

The described traps offer a substantially open structure for marine life to enter said trap. Then, the trap may in turn be closed to catch the marine life therewithin and prevent their escape therefrom in a positive and secure manner. The trap is less expensive in overall operation, requires less effort and less raw materials, is much more effective in operation, can be very easily removed or dumped into the hold of a fishing vessel, can be closed from above the surface of the water being fished, and if lost will not trap fish therein or other marine life as do conventional traps with the resultant waste of such marine life.
