the present invention is directed to a fish cleaning device especially suited for catfish but usable with other fish as well . with reference now to the drawings in general and to fig1 in particular , there is shown therein a fish cleaning device constructed in accordance with a preferred embodiment of the present invention and designated herein generally by the reference numeral 10 . the device 10 preferably comprises an elongate tray 12 sized for supporting at least a portion of the body of a catfish . more preferably , the tray 12 is sized to support catfish of varying sizes . the tray 12 has a body area 14 for supporting the body of the fish and a head area 16 for supporting the head of the fish . the tray 12 further has a first free or tail end 18 and a second or head end 20 . the tray 12 may be flat or curved , and may or may not have upwardly turned edges . the device 10 further comprises a piercing member such as the blade 22 . the blade 22 is sized to pierce the spinal cord of the fish without severing the head of the fish . in a preferred embodiment , the blade 22 is a strip of flat , rigid metal such as steel , having a first end 24 and second end 26 . the blade 22 preferably is about 1 / 2 to about 1 inch wide , and more preferably about 3 / 4 inch wide , as this is wide enough to sever the spinal cord of most catfish without being wide enough to sever the head . the length of the blade 22 will , of course , depend on how the blade is mounted , but in the preferred configuration illustrated herein the blade is about 31 / 2 inches long . the first end 24 of the blade 22 is sharpened or otherwise adapted to pierce the body of the fish and intersect the spinal cord behind the head . preferably , the end 24 is curved , as best seen in fig3 for a reason that will become apparent . the second end 26 is mounted in a manner to be described . when mounted , as hereinafter described , the blade 22 is long enough to extend a substantial distance into the body of the fish . a hole 28 preferably is formed in the tray 12 to receive the sharp end 24 of the blade 22 so that it does not rest on the surface of the tray . this prevents dulling of the blade and secures the sharp edge during storage and transport . the blade 22 is mounted to the device 10 for movement between a load ( and unload ) position and an operating position . in the load / unload position , the blade 22 is positioned so that a fish may be placed on and removed from the tray 12 . in the operating position , the blade 22 is positioned vertically over the tray 12 disposed to pierce the body of the fish behind the head ( see fig9 a ). for supporting the blade 22 , the device 10 is provided with a vertical member 30 that supports a horizontal arm 32 . the vertical member 30 has a first or upper end 34 and second or lower end 36 . the lower end 36 is secured to the head end 20 of the tray 12 . the horizontal arm 32 comprises an elongate body portion 40 with a first forward end 42 and a second rear end 44 . the upper or second end 26 of the blade 22 is attached to the first end 42 of the arm 32 by some suitable means , such as the screw 45 . for a reason that will become apparent , the upper end 26 of the blade 22 or the first end 42 of the arm 32 , or both , comprises a flattened head 46 . in addition , a handle 48 may be provided at the second or upper end 26 of the blade 22 for lifting and manipulating the blade . as will be appreciated , the configuration of the vertical member 30 and the means by which it is affixed to the head end 20 of the tray 12 can vary . in the embodiment shown in fig1 the vertical member 30 is a length of angle iron supported by a frame 50 . the preferred frame 50 , seen best in fig2 and 3 , comprises a pair of rails 54 and 56 providing support underneath the tray 12 . the lower end 36 of the vertical member 30 is welded between the two ends of the rails 54 and 56 , or affixed thereto in some other suitable manner . as indicated previously , the blade 22 is movably mounted to the vertical member 30 . with continuing reference to fig1 and turning now also to fig4 and 5 , the preferred assembly for connecting the rear or second end 44 of the arm 32 to the vertical member 30 will be explained . for moving the blade 22 between the load / unload position and the operating position , the second or rear end 44 of the arm 32 preferably is pivotally attached to the vertical member 30 . alternately , the end 44 of the arm 32 may be vertically slidable on the vertical member 30 . most preferably , the arm 32 is both slidably and pivotally mounted to the vertical member 32 , as this greatly increases the maneuverability of the blade 22 and thus the fish supported on it . mounted in this way , the blade can easily be lifted away from the tray 12 to place the fish belly down on the tray , and then inserted into the neck of the fish to kill it instantly without detaching the head . cleaning of the fish is facilitated by rotating it on the tray . thus , the arm 32 preferably is rotatably mounted to the vertical member 30 . all of these manipulations of the fish are readily accommodated by the connecting assembly 60 between the rear end 44 of the arm 32 and the upper end 34 of the vertical member 30 . as best seen in fig1 a vertical track 62 is supported a distance in front of the upper end 34 of the vertical member 30 . this track 62 comprises a plate 64 defining a vertically oriented slot 66 . referring still to fig4 and 5 , the rear end 44 of the arm 32 comprises a shaft 70 from which extends an end portion terminating in a free end 74 . the shaft 70 shown is square in cross section and sized so that opposing flat sides are slidably receivable in the slot 66 so as to prevent rotation of the shaft when the sides are so engaged . it should be apparent that other geometric configurations , such as hexagons and octagons , will likewise provide parallel opposing sides to engage the slot 66 , and that any equilateral polygon with an even number of sides in excess of three will also serve . it will now also be understood that the entire arm 32 may be shaped the same as and be continuous with the shaft 70 , but that this is not essential to the operation of the invention . the end portion preferably comprises a cylindrical extension 72 having a diameter smaller than that of the shaft 70 . thus , the cylindrical extension 72 will freely rotate and slide in the slot 66 , while the shaft 70 will only slide and not rotate therein . the rear end 44 of the arm 32 preferably is movable between a sliding position ( fig4 ), in which the shaft 70 is positioned in the slot 66 , and a rotating position ( fig5 ) in which the cylindrical extension 72 is positioned in the slot . this is accomplished by moving the arm 32 horizontally . to prevent the arm 32 from being pulled completely out of the track 62 , the free end 74 of the cylindrical extension 72 preferably is provided with a stop , such as the disk 80 secured to the free end by a cotter pin 82 or some other suitable means . even more desirably , the connecting assembly 60 includes a biasing device for urging the rear end 44 of the horizontal arm 32 into the sliding position , that is , the position in which the shaft 70 is engaged in the slot 66 . with continued reference to fig4 and 5 , the preferred biasing device now will be described . the biasing device preferably is a simple spring mechanism and more preferably a coil spring 86 compressibly supported on the cylindrical extension 72 . the spring 86 has a diameter sufficient to receive the cylindrical extension 72 , and a length when relaxed about the same as the length of the cylindrical extension . the spring 86 has a first end 88 and a second end 90 . the first end 88 is connected either to the stop 80 or the free end 74 of the cylindrical extension 72 . thus , the first end 88 of the spring 86 is stationery relative to the arm 32 . the second end 90 of the spring 86 is attached to a movable disk or washer 92 slidably received on the shaft 70 between the cylindrical extension 72 and the rear end 44 of the arm 32 . in this way , when the arm 32 is pulled away from the vertical member 30 , the shaft 70 is pulled out of the slot 66 and the spring 86 is compressed between the washer 92 and the disk 80 , as seen in fig5 . this allows a portion of the cylindrical extension 72 to extend through the slot 66 thereby allowing the arm 32 to be raised and lowered slidably in the track as well as rotated therein a full 360 degrees . when the arm 32 is released , the spring 86 expands to its resting length and the cylindrical extension 72 is pulled back inside the track 62 behind the slot 66 . this , in turn positions the polygonal shaft 70 inside the slot 66 so that the sides of the shaft are slidable , but non - rotatably engaged in the slot . returning to fig1 - 3 , other advantageous features of the invention will be explained . various tools are used in the process of cleaning fish . typically these tools include a mallet or hammer , a knife , and a pair of pliers . the device 10 of the present invention includes an accessory support panel 98 for supporting one or more such tools in a handy location . preferably , the panel 98 takes the form of a cross member with a pair of laterally extending planar portions 100 and 102 . the planar portions 100 and 102 are provided with openings for receiving the tools . for example , a large round hole 104 is provided in the planar portion 102 for receiving the handle of a mallet . similarly , smaller holes 106 and slots 108 are provided in the planar portion 100 for receiving plier handles and knife blades , respectively . of course , it will be understood that other means such as hooks , clamps , hook and loop fabric , or magnetic supports , or any combination of these , could be utilized for this purpose instead of the holes and slots shown herein . with continuing reference to fig1 and turning now also to fig6 - 8 , yet another desirable feature of the present invention is illustrated . the device 10 is , of course , small and lightweight enough to be carried by the fisherman into and out of a boat , along the shore , outside a cabin , or anywhere else which might be chosen for cleaning the fish . the portability and versatility of this device is highly desirable , as it is best to clean the fish immediately after catching them . thus , the device 10 preferably is adapted to be secured to several different types of supports , such as the ground , a nearby tree or a worktable or other surface . to that end , the device 10 may include a first horizontal member 110 secured to the vertical member 30 . the first horizontal member 110 preferably is an elongate bar having a pair of opposing ends 112 and 114 ( fig1 and 3 ) with a hole 116 and 118 in each end . a strap 122 ( fig6 ) is included for connection to the ends 112 and 114 through the holes 116 and 118 . the strap 122 , then , can be secured adjustably connected around a tree 124 ( fig6 ) or pole or any other vertical support . in some instance it is desirable to stake the device to the ground , for use at the water &# 39 ; s edge , for example . the device 10 preferably is provided with a second horizontal member 126 also attached to the vertical member 30 , but lower on the vertical member near the lower end 36 and parallel to the first horizontal member 110 . the second horizontal member 126 preferably has a pair of opposing ends 128 and 130 with holes 132 and 134 , respectively . the device 10 may include a stakes 136 , each of which is receivable in the holes 116 , 118 , 132 and 134 . in this way , the device can be secured to the earth by driving the stakes through the aligned holes and into the earth , as shown in fig7 . still further , it may be preferable to secure the device 10 to a flat surface such as a worktable . for this purpose , the device 10 may be provided with a pair of self tapping screws 138 . the second horizontal member 126 , which is near the lower end 36 of the vertical member 30 , may be provided with holes 140 sized to receive the screws 138 . thus , the device 10 can be secured to a table or other surface 142 , as shown in fig8 by inserting the screws 138 through the holes 140 and then into the table 142 . of course , nuts and bolts could be substituted for the self - tapping screws , if holes are pre - drilled in the table 142 . alternately , a clamp or bracket assembly of some sort could also be employed to secure the second horizontal member 126 to the worktable 142 . having described the structure of the device 10 in its preferred embodiment , its use and operation now will be explained with reference to fig9 a - 9d . first , the fisherman must provide the fish . next , the support for the device , and the means for securing the device to the support is selected . then , the device is secured to the support in the manner described herein . having secured the device 10 , the fish 150 first is placed belly down on the tray 12 with its head on the head area 16 of the tray and with the blade 22 positioned to pierce the body of the fish centrally behind the head , as illustrated in fig9 a . the blade 22 is pushed through the body of the fish 150 by pounding a mallet on the flattened head 46 on the upper end of the blade . the blade 22 immediately severs the spinal cord and kills the fish instantly . now a further advantage of the vertical track 62 will be apparent . as the mallet hits the head 46 of the blade 22 and pushes the blade down into the body of the fish 150 , the rear end 44 of the arm 32 slides downwardly in the slot 66 . yet , because of the flattened sides of the shaft 70 , the arm 32 cannot turn from side to side . thus , the track 62 also serves as a guide to maintain the blade 22 in a vertical position as it impacts the smooth , curved back of the fish 150 . this prevents the blade 22 from glancing off the fish 150 and from deviating to the either side of the spinal cord . in addition , the curved end 24 of the blade 22 facilitates a direct downward path . next , using a knife , a circumferential incision is made behind the head . this may be carried out by making a partial cut then rotating the fish a quarter turn , making a second partial cut , and rotating the fish another quarter turn . this is repeated , as shown in fig9 b , 9c and 9d , until the fish 150 has been rotated a full 360 degrees and a complete circular cut has been made . next , the fish 150 is skinned and gutted in a known manner . when the cleaning process is complete , the head is removed and discarded with the innards . now it will be apparent that throughout the cleaning process , the fish 150 is stabilized by the blade 22 and supported on the tray 12 , yet still can be freely rotated . thus , a major advantage of the present invention is employed . to rotate the fish 150 , the user merely pulls gently on the body of the fish to compress the spring 86 to place the arm 32 in the rotatable mode . release of the tension on the fish 150 pulls the arm 32 back into the non - rotating mode , while still allowing vertical movement and lifting of the fish . as explained , the process of cleaning the fish 150 involves the use of certain tools , including a mallet , a knife and a pair of pliers . accordingly , the present invention contemplates a fish cleaning kit 152 , which is illustrated in fig1 . the kit 152 comprises the device 10 , as described hereinabove , and a plurality of tools , such as a mallet 154 , a knife 156 and a pair of pliers 158 . as previously described , the device 10 can be mounted to a tree , to the ground or to a worktable . thus , the preferred kit 152 will also include an adjustable strap 122 , a pair of stakes 136 , or a pair of screws 138 . even more preferably , the kit 152 will include all these items to maximize the mounting options . now it will be appreciated that the present invention provides important improvements in devices for cleaning fish and for cleaning catfish in particular . the device kills the fish instantly before the cleaning process begins , and without severing the head . in this way , cleaning the fish is as easy as possible without compromising humane treatment of the fish . also important is the versatile mounting assembly , which allows the same device to be mounted in at least three different ways . changes can be made in the combination and arrangement of the various parts and elements described herein without departing from the spirit and scope of the invention as defined in the following claims .
a fish cleaning device that first kills the fish instantly and humanely and then stabilizes the fish for cleaning . the piercing member used to kill the fish is vertically and horizontally movable . in addition , the piercing member is pivotally and rotatably mounted . in this way the fish can be rotated for skinning and held firmly for gutting by the same piercing member . the device is equipped with a mounting assembly by which it can be firmly and removably mounted to the trunk of a tree , to the ground , or to a worktable or other surface .
