referring principally to fig1 - 5 , the preferred embodiment of the present fishing lure is identified generally by the reference number 10 . lure 10 includes a lure body ( 1 ) is composed of two halves ( 13 and 14 ) which are manufactured with a recess on the inner surface of each half of a depth of approximately one and one half times the diameter of the hook shaft . ( the two halves 13 and 14 may be molded plastic or may be machined from wood or metal on a cnc machine or comparable equipment ). when the two halves 13 and 14 are joined this creates a cavity 112 through which hook 12 may rotate freely about the hook shaft 3 . the cavity 112 opens through the top side of the lure body 1 with an origination of the opening a short distance from the tail 114 of the lure body 1 and a termination at approximately mid point of the body 1 . the cavity 112 is wide enough to accommodate the body of hook 2 and to allow for hook keepers 6 and 7 penetration into the cavity 112 . the cavity 112 lies equidistant and parallel to the head - to , tail centerline of the lure 10 . the cavity 112 opens through the bottom side 116 of the lure body 1 with an origination the same as the top cavity opening and terminates at a point approximately mid - way between the head and tail 114 of the lure body 1 . this provides an opening through which the shank 118 of the hook 2 may pass when it is placed into the “ hidden ” or “ set ” position ( as shown in fig1 ). all inner corners and exposed edges inside the cavity 112 should be slightly rounded to prevent damage to the fishing line should there be any contact . hook shaft 3 passes through the approximate middle of the lure body 1 , eye 4 of hook 2 and cavity 112 at a point that allows hook 2 to rotate freely upward and downward through the body cavity 112 without any interference between the tail end of the cavity and the bend of the fish hook shank 118 . hook keepers 6 and 7 extend inward to cavity 112 in the lower quadrant of each half of the lure body 1 . hook keepers 6 and 7 are , in the preferred embodiment , nylon bristles , but may be made of some other suitable flexible , durable material such as kevlar or delrin . the nylon bristles are of approximate diameter { fraction ( 1 / 16 )}″ and are set into holes provided in the body halves 13 and 14 . alternative means of retaining the hook may be used . for example , referring to fig1 , the hook retainers 6 and 7 may be structured as small screws of delrin , nylon , teflon or kevlar . the outer ends of such structures should be slightly rounded . the screws ( hook keepers 6 and 7 ) would be screwed into the two body halves 13 and 14 to the proper depth to allow the hook shank 118 to pass between them and adjusted as wear may occur .) the inner ends of the hook keepers 6 and 7 extend into the cavity 112 of the body 1 to a sufficient distance that their inner end lies short of the head - to - tail centerline of the cavity 112 by a distance equal to approximately ¼ the diameter of the hook 2 . thus , the hook 2 may then be pushed or pulled between the ends of the keepers 6 and 7 as the hook 2 is rotated about the hook shaft 3 . to begin fishing with the lure , a fishing line 11 must be attached to the hook 2 . it is assumed that a rod and reel ( not shown in the drawings ) are used in the operation of the lure 10 . the fishing line 11 is passed down through the line aperture 12 provided in the lure body 1 . the edges of line aperture 12 are rounded to prevent damage to the line 11 . the hook 2 is pushed up into it &# 39 ; s full upward position ( shown in dotted line in fig3 ). the line 11 is then attached to the hook 2 by wrapping it around the exposed , bent portion of the hook shank 118 and is secured via a “ double improved cinch knot ” or other similar knot 122 . the tag ends of the knot 122 are then trimmed as closely as possible . the hook 2 is then pushed down past the hook keepers 6 and 7 into the “ hidden ” position ( shown in unbroken lines in fig3 ). hook 2 is held in the hidden position while the line 11 is pulled upward through the line orifice 12 . the knot 122 will slide forward on the hook 2 to a point where it is at or near the downward bend of the hook 2 . a lower hook stop 5 is set in the lure cavity 112 and acts as a lower stop to keep the hook 2 from dropping out of the lower cavity opening 120 . when the hook 2 is in the “ hidden ” position it &# 39 ; s shank 118 will lie between the hook keepers 6 and 7 and the lower hook stop 5 . the lure can then be cast out and retrieved just as any conventional crank bait . a weight cavity ( 9 ) is set into the nose of the lure . weighted metal balls 110 are placed into a weight cavity 9 . the weight thus provided in the indicated position effects a nose - down orientation for the lure 10 while in use in the water , and also provides noise as the balls 110 strike the inside of the cavity 9 as the lure 10 wobbles from side to side during a retrieve . when a strike occurs the fisherman must draw the rod tip back forcefully and quickly , as is required with most baits , to drive the hook point into the fishes mouth . when the fish holds the lure in it &# 39 ; s mouth this creates a back pressure against the line 11 . when the rod tip is drawn back forcefully , the line 11 exerts sufficient pressure against the hook 2 to rotate the hook shank 118 upward past the ends of the two hook keepers 6 and 7 . the hook 2 rotates upward until the hook shank 118 contacts the lower side of the portion of lure body 1 that serves as an upper hook stop 8 . the upper hook stop 8 acts to keep the hook 2 from turning downward toward the lure body . the point of hook 2 is then exposed and is driven into the fish &# 39 ; s mouth . in fig6 a top water embodiment is shown . the manufacture and operation of the lure are much the same as that shown for the embodiment of fig1 - 5 . the lure 10 in this embodiment uses a cam 15 ( shown in fig8 ) to deploy and supply the upward force for the hook 2 . the cam 15 and cam shaft 17 should be made from stainless steel or a durable material such as kevlar or a high grade of molded plastic . the cam 15 is supplied with an eyelet 16 for connecting the cam cable 27 to the line attachment eyelet 28 . the fishing line 11 is attached to the eye 28 of the cam cable 27 . the cam cable 27 is supplied with a crimped ball 105 . the ball 105 interacts with body 1 as shown in fig8 to keep the hook 2 and cam 15 from dangling from the body 1 when the hook 2 is in the hidden position . the hook 2 is deployed as in the preferred embodiment . the weight chamber 9 and weighted balls 110 of the earlier embodiment are removed in the embodiment of fig6 and following . the hook keepers 6 and 7 are exactly as in the preferred embodiment . in fig1 , a diving lure embodiment is shown . two rollers 23 and 25 have been added to route the line 11 into position to supply the upward force to release and expose the hook 2 . the line 11 is routed through the line aperture 12 and passes behind the bottom roller 23 ( mounted on shaft 24 ) and forward of the top roller 25 ( mounted on shaft 26 ) and out the opening above the top roller 25 . line 11 is then routed back down through the opening above the upper roller 25 and the line 11 is secured to the hook shank 118 as in the preferred embodiment . the hook keepers 6 and 7 for this embodiment are exactly as in the preferred embodiment . it becomes apparent from these descriptions that slight variations could be made in the retention and deployment mechanism of the hook 2 depending on the body shape of the lure 10 , but it should be understood that the basic design / operation remains the same — that a single hook is placed into and kept in a cavity providing snagless operation until such time that the fisherman desires to deploy the hook , said hook being deployed by back pressure against the attached fishing line . although the invention has been described with reference to specific embodiments , this description is not meant to be construed in a limited sense . various modifications of the disclosed embodiments , as well as alternative embodiments of the inventions will become apparent to persons skilled in the art upon the reference to the description of the invention . it is , therefore , contemplated that the appended claims will cover such modifications that fall within the scope of the invention .
a weedless fishing lure of hard bodied design of multiple embodiments , which is adapted to be connected to a fishing line , the one single hook of which is connected to the lure body by a through shaft and rotates about the shaft , said body containing a cavity large enough to completely house the hooking point of the hook while it is being fished , and having a mechanism to keep the hook hidden until deployment is desired , said hook being deployable to the hooking position by back pressure against the attached fishing line and said hook remaining deployed by back pressure against the attached line .
