referring to the drawings , and with particular reference to fig1 and 2 , a fishing rod holder and hook setting device 10 embodying the present invention includes a holder 12 for supporting a fishing rod 14 . preferably , the holder 12 comprises a tube 16 for receiving the handle of the fishing rod 14 . this configuration permits easy and rapid removal of the fishing rod 14 from the tube 16 once the hook at the end of fishing line 17 carried by rod 14 has been set . the holder and setting device 10 is adapted to automatically swing the tube 16 and the fishing rod 14 in an upwardly direction toward the vertical to set the hook carried on the fishing line 17 in a fish in response to a downward tension on the fishing rod 14 and the tube 16 caused by the fish taking the bait on the hook . to achieve this movement , the tube 16 includes two spaced apart depending ears 18 which have a common axis about which the tube 16 and the ears 18 rotate , the ears 18 having coaxial aligned openings 20 along this axis of rotation . interposed between the ears 18 , to provide a support about which the tube 16 is rotated and to enclose and support a pawl and ratchet mechanism 24 for cocking the holder and setting device 10 , is a support housing 26 . the pawl and ratchet mechanism 24 comprises a ratchet wheel 25 mounted for rotation within the support housing 26 , and including slanted teeth 28 , a first catch member or pawl 64 , and a second catch member or pawl 66 , the ratchet wheel 25 and the support housing 26 having coaxially aligned openings 30 along the common axis of the aligned openings 20 . a shaft 32 extends through the aligned openings 20 and 30 and is rotatable relative to the support housing 26 and the ears 18 . the shaft 32 also is provided with a square mount 34 , received in a rectangular opening 35 in the ratchet wheel 25 so that the ratchet wheel 25 rotates with the shaft 32 . collar 36 is provided on the shaft 32 to maintain the shaft 32 in position within the support housing 26 . referring to fig2 , 12 and 13 , to securely mount the support housing 26 in position for fishing , a mounting post 40 depends downwardly from the support housing 26 and is rotatably received by a ground engaging support element 42 . the support element 42 is preferably in the form of a stake and comprises an upper tubular stake portion 44 adapted to receive the mounting post 40 which is freely rotatable therewithin , and a lower stake portion 46 for insertion into the ground . a foot bracket 48 is secured to the upper tubular portion 44 of the support element 42 to aid in inserting the lower stake portion into the ground . a finger hole 50 is provided in the bracket 48 to aid in removing the support element 42 from the ground . it should be noted that the support housing 26 may be securely mounted in a fixed position in any manner , such as being mounted on a boat wherein the support element 42 would be adapted for attachment to the side of the boat . with references to fig2 , and 11 , springs 52 provide variable rotary tension between the ratchet wheel 25 and the tube 16 so as to tend to rotate the tube 16 upwardly toward a vertical position . in the illustrated embodiment , springs 52 comprise two planer coiled clock springs 54 disposed within cavities 56 defined on the exterior surface of each ear 18 . the clock springs 54 are in substantially coaxial alignment with the ratchet wheel 25 and the ears 18 . the outer end 58 of each clock spring 54 is affixed in a slot 59 in the edge of the cavity 56 so as to rotate the ear 18 and the tube 16 . the inner end 60 of each coiled spring 54 is attached in a slot 61 provided in each end of the shaft 32 so as to rotate with the ratchet wheel 25 . the orientation of the coiled clock springs 54 within the cavities 56 is such that when the clock springs 54 are wound and placed under tension , the springs 54 tend to rotate the tube 16 upwardly from an essentially horizontal position when the ratchet is held in a fixed position relative to the support housing 26 by a catch member or panel 64 on the housing 26 . spring cover plates 62 are disposed over the cavities 56 so as to enclose the clock springs 54 therewithin . turning now to fig1 , 4 , and 6 through 8 , a pair of catch members or pawls 64 and 66 are provided to selectively apply any desired tension to the clock springs 54 thereby providing an adjustable release tension for the holder and setting device 10 . to accomplish this , the catch members 64 and 66 selectively engage the teeth 28 of the ratchet wheel 25 . the first catch member 64 includes a trigger lever 68 pivotally mounted by a pin 70 to the support housing 26 . at the interior end of the lever 68 is a tongue 72 which selectively engages the teeth 28 of the ratchet wheel 25 to prevent rotation of the ratchet relative to the housing 26 , when the tube 16 is rotated in a downwardly direction , thereby applying tension to the coiled clock springs 54 which tends to swing the holder 12 upwardly . a second catch member 66 includes a trigger lever 74 pivotally mounted by a pin 76 between the ears 18 . the trigger lever 74 has at its interior end a tongue 78 for selective engagement with the teeth 28 of the ratchet wheel 25 , and which rotates the ratchet wheel 25 simultaneously with the tube 16 when the tube 16 is rotated in an upwardly direction , thereby rotating the clock springs 54 relative to the stationary support housing 26 without affecting the state of tension of the springs 54 . thus , to cock the holder and setting device 10 and to apply the desired tension to the clock springs 54 , the first catch member 64 engages the teeth 28 while the tube 16 is rotated downwardly to apply tension to the springs 54 . then , the trigger lever 74 of the second catch member 66 is pulled downwardly so as to engage the tongue 78 with the teeth 28 . the second catch member 66 being so engaged , the tube 16 is rotated upwardly toward a vertical position which rotates both the ratchet wheel 25 and the coiled clock springs 54 as a unit so as not to alter or affect the tension on the springs 54 . when the tube 16 reaches an essentially vertical position , the first catch member 64 is engaged with the teeth 28 of the ratchet wheel 25 , and the procedure is repeated until the desired tension has been placed on the clock springs 54 . the device 10 has then been cocked and is prepared for setting . to set the holder and setting device 10 after having been cocked , the tube 16 is releasably retained in a downwardly , essentially horizontal position against the tendency of the springs 54 to rotate the tube 16 upwardly . to retain the tube 16 in such a position , a friction release latch 80 is provided to releasably secure the tube 16 to the support housing 26 . once the holder and setting device 10 is so set , and a downward tension on the fishing rod 14 and the tube 16 occurs , the friction release latch 80 is released , thereby allowing the clock spring 54 to rotate the tube 6 upwardly to set the hook . the downward tension on the fishing rod 14 required to release the friction release latch 80 will vary according to the amount of tension which has been selectively imposed on the springs 54 as described in more detail below . with reference to fig1 , and 4 through 10 , the friction release latch 80 includes a latch member 82 pivotally mounted to the support housing 26 for rotation about an axis substantially perpendicular to the rotational axis of the tube 16 and the ratchet wheel 25 . the latch member 82 has a friction gripping surface preferably in the form of grooved or notched surface 84 on one face of one end thereof and an annular flange 86 on the opposite end to form a pivot point . tube 88 extends outwardly from the support housing 26 and is inserted within the flange 86 . a spiral torsion spring 90 is disposed within the tube 88 and is secured at one end 92 within the tube 88 and at its other end 94 to the center of the annular flange 86 . the torsion spring 90 is coaxial with the axis of rotation of the latch member 82 and is oriented within the tube 88 so as to tend to pivot the latch member 82 downwardly away from the tube 16 as shown in fig8 . the tension of the torsion spring 90 may be adjusted by pulling the latch 82 outwardly and rotating the same relative to the housing 26 . to secure the latch member 82 to the tube 16 , the friction release latch 80 also includes a tab member 96 depending downwardly from the tube 16 . the tab 96 also has a friction gripping surface preferably in the form of grooved or notched surface 98 on one face thereof . the grooved surfaces 84 and 98 are disposed respectively on the latch member 82 and the tab 96 so as to face each other when the latch member 82 is in a pivoted upright position . when the tube 16 is in a downward , essentially horizontal position , and the latch member 82 is in a pivoted upright position , the grooves or notches on the friction gripping surfaces 84 and 98 interlock with each other , and since the springs 54 are applying tension to the tube 16 when the tube 16 is in such a position , the grooved surfaces 84 and 98 , when interlocked , are maintained in this position by friction therebetween so as to retain the tube 16 in the downwardly , essentially horizontal position . the friction force or release tension between the gripping surfaces 84 and 98 is directly dependent on the tension of the coiled springs 54 so that the greater the tension applied to the springs 54 , the greater the friction force or release tension which holds the latch member 82 and the tab 96 together . when a downward tension imposed on the fishing rod 14 and the tube 16 resulting from a fish pulling on the fishing line 17 overcomes the friction force between the latch member 82 and the tab 96 created by the springs 54 , the rotational force from the torsion spring 90 forces the latch member 82 to disengage from the tab 96 and pivot downwardly . this releases the tube 16 , and the coiled clock springs 54 quickly rotate the tube 16 upwardly to an essentially vertical position , thereby pulling on the line and setting the hook in the fish . as can be seen from the above , the present invention is not overly complicated and is easy to assemble and operate . furthermore , the present invention is not particularly expensive to construct inasmuch as all of the components thereof , except for the coiled springs 54 and the torsion spring 90 , may be formed from injection molded plastic . also , the present invention provides for easy and rapid removal of the fishing rod from the device , and the fishing line carried by the fishing rod remains tight with the fishing reel and is not utilized as a part of the triggering or releasing mechanism . finally , the release tension or force of the friction release latch can be varied and is readily adjustable for various fishing conditions , size and species of fish , and areas to be fished , by merely applying the desired tension to the coiled clock springs . furthermore , the angle of the tube may be varied by engaging the grooved surface of the latch member along any portion of the grooved surface of the holder tube tab , for it is not necessary that the entire grooved surface of the latch member be engaged with the entire grooved surface of the tab member . while a certain illustrative embodiment of the present invention has been shown in the drawings and described in considerable detail , it should be understood that there is no intention to limit the invention to the specific form disclosed . on the contrary , the intention is to cover all modifications , alternative constructions , equivalents , and uses falling within the spirit and scope of the invention as expressed in the appended claims .
a fishing rod holder and hook setting device embodies a fishing rod holder tube mounted for vertical swinging rotation on a support housing adapted to be ground anchored in a fixed position . a ratchet wheel mounted for rotation within the support housing is interconnected with the holder tube by clock springs which , when under tension , tend to rotate the holder tube upwardly toward a vertical position . catch members adapted for selective engagement with the ratchet wheel are provided to selectively apply a desired tension to the springs by repeated oscillatory rotation of the holder tube . a friction latch releasably retains the holder tube in a downward , relatively horizontal position , against the action of the clock springs . when a downward tension on the holder tube occurs from a pull on the line of a retained fishing rod , the friction latch is released whereby the clock springs swing the tube and thereby the pole upwardly to exert a tug on the fishing line and set the hook in a fish taking the bait on the hook .
