the angling device of the instant invention is depicted generally in fig1 , and 3 at numeral 10 . as can be seen by reference to fig1 the device 10 provides a pair of buoyant hulls 11 and 12 which are hollow , air - filled buoyant hulls . in turn , hulls 11 and 12 are rigidly connected to each other by bridge 13 . with reference to fig3 where the device 10 is depicted outside of the water , it can be seen that hulls 11 and 12 are further connected to vertical planes 14 and 16 which extend beneath buoyant hulls 11 and 12 and depend into the water as shown in fig1 and 2 to provide a plane against which the angler 15 can pull device 10 . with further reference to fig3 it can be seen that vertically depending planes 14 and 16 are further provided with adjustable foils or fins 21 , 22 , 23 , and 24 . these adjustable foils can be rotated up and down along swivel disks 26 and 27 as depicted in fig4 so that the angle of the foil 21 and 22 can be adjusted in accordance with the fisherman &# 39 ; s desire as to the planing action of the device 10 . further attached to buoyant hulls 11 and 12 are decorative vertical fins 28 and 29 which provide a decorative effect , making the device 10 appear to be fish - like . vertical fins 28 and 29 also provide structural integrity for the attachment of bridge 13 as can best be shown in fig6 . further attached to buoyant hulls 11 and 12 are horizontal attachment strips 31 and 32 which are provided with holes 33 to allow the fisherman 15 to attach the line for controlling the device 10 . as can be seen with reference to fig6 , 8 , 9 , and 10 , the horizontal attachment strips 31 and 32 are provided on both sides of the device 10 so that it can be used from either a right - side or a left - side position . with reference to fig3 and 6 , it can be seen that bridge 13 is provided with upright post 35 to which spring 34 is attached . trip flag post 36 is attached to the upper portion of spring 34 by inserting post 36 within spring 34 in a manner well known in the art . trip flag 37 is attached to pole 36 . as can be seen with reference to fig3 , and 5 , trip flat 37 can either be in the horizontal position as shown in fig4 or in the upright position as shown in fig5 depending on whether or not it is held down by release hook 38 which is attached to pole 36 and which can be slidably released . it can be seen by reference to fig3 that release mechanism 40 provides a mechanism by which the strike of a fish is indicated by the upright movement of trip flag 37 and the release of the line having the lure or bait is made so that the fish can be retrieved by the angler 15 . the operation of release 40 is depicted in fig7 , 9 , and 10 . release 40 is in essence a cylindrical rod 41 extending rearwardly from bridge 13 . rod 41 is provided with a slit 42 separating rod 41 into two halves . rod 41 is further tapered or threaded to allow keeper 43 , which is an annular ring , to be slid or threaded along rod 41 to compress slit 42 together . when line 50 is placed within slit 42 as depicted in fig7 keeper 43 is urged toward bridge 13 along rod 41 . the tension on the line release 40 is increased . if a pull or sufficient force is felt at hook 51 , line 50 is removed from the slit 42 in release 40 and line 51 is allowed to be free of release 40 . the force along line 51 further pushes hook 38 off of tapered end 41 so that trip flag 37 is released to stand in an upright position as depicted in fig5 . it is noted that other attachment holes such as holes 61 and 62 on fig4 and 5 are provided on both vertical planes 14 and 16 so that additional methods can be employed to attach line 50 to the device 10 . the operation of the device will now be described . there are basically two ways to utilize the device . the first method is to employ a single line as depicted in fig1 . the single line allows an angler to attach line 70 through horizontal attachment point 32 through one of the holes 33 in horizontal attachment point 32 whereby the line is then run back through hole 62 and thereupon up through slit 42 in releasse 40 as all depicted in fig7 . by utilizing the single - line method , if a fish should strike or hook himself on hook 51 as depicted in fig7 the pull on line 50 would release the trip flag 37 and line 70 would pull through hole 33 in horizontal attachment 32 . at that time , line 50 , which is a continuation of line 70 , after releasing from release mechanism 40 , would allow the line to move so that hook 51 moves up to hole 62 in vertical plane 16 . when that occurs , device 10 is positioned near the hooked fish ( not shown ) which is hooked onto hook 51 , and both fish and device 10 are reeled in toward fisherman 15 in a normal manner . by use of the single - line method as shown in fig1 , and 8 , an angler need not use an additional rod and reel to position device 10 . if one wished to use a two - line method , it is possible for angler 15 to attach a separate line 80 onto the device 10 by means of placing it in one of the holes 33 in horizontal attachment point 32 and thereupon up to hole 61 for a rigid attachment . by placing line 80 in a different hole 33 in horizontal attachment 32 , the angle of device 10 with respect to the fisherman can be varied so that the device will move farther upstream or farther downstream as desired . the attachment hole utilized varies with the conditions ; however , it gives the fisherman great flexibility in determining the placement of the device 10 . similarly , when using a single - line method , it is possible to route the single line through a different hole 33 in horizontal attachment 32 to achieve the same angled relationship , thus placing device 10 where desired . still in reference to fig9 where it can be seen that a separate line 50 having hook 51 is routed into the line release 40 as previously described with reference to line release 40 so that when a fish attaches itself to hook 51 , the resulting pull releases trip flag 37 and line 51 . when that takes place , the fisherman can see that the line has been released . device 10 would remain in essentially the same position ; however , the fish is only attached to line 50 and is free from device 10 . the fisherman thus lands the fish in a normal manner . a further method of attaching the device is depicted in fig1 in which a single line 50 is routed up through hole 33 in horizontal attachment 32 , then up through hole 61 , back to hole 62 , and then up through line release 40 in the same manner as previously described . if a fish should impale itself upon hook 51 , the resulting pull would release trip flag 37 as well as line 50 . however , the device would remain attached to line 50 and since it is routed up further to the nose by way of hole 62 of the device , the device would then plane toward the fisherman , thus helping to retrieve the fish . it should be noted that additional decorative embellishments such as teeth as depicted in fig1 and 2 could be utilized with the device in order to further enhance its attractiveness . the use of foils 21 , 22 , 23 , and 24 as previously described to set the plane of the device in an adjustable fashion allow greater control by the fisherman at which depth the device 10 will ride in the water . in strong current , foils 21 , 22 , 23 , and 24 reduce the drag of the device 10 as the device 10 is raised slightly out of the water so that hulls 11 and 12 are not as deep as they previously were and the resultant pull on the device is reduced even as to the flow of the water is increased , thus making it much more convenient for the fisherman to employ the device without excessive drag . it is to be understood in the preferred embodiment that the device is composed of a polycarbonate or polystyrene plastic ; however , any suitable material which is water - resistant could be employed with varying degrees of quality . it is contemplated that the device could be manufactured in a number of bright colors which would allow the device 10 to be easily seen even in twilight hours when many fishermen would be utilizing it . although specific applications , materials , components , connections , sequences of events and methods have been stated in the above description of the preferred embodiment of the invention , other suitable materials , other applications , components , and process steps as listed herein may be used with satisfactory results and varying degrees of quality . in addition , it will be understood that various other changes in details , materials , steps , arrangements , parts , and uses which have been herein described and illustrated in order to explain the nature of the invention will occur to and may be made by those skilled in the art , upon a careful reading of this disclosure , and such changes are intended to be included within the principles and scope of this invention as hereinafter claimed .
