  • Patent number: 4251940
    Abstract: Trolling apparatus with controlled reel rotation is described which includes a large diameter reel rotatably mounted on a base with a drag assembly in contact therewith, and a handle for rotation mounted directly to the perimeter of the reel, with line from the reel passing over a pulley and through a bracket for bait attachment. The controlled rotation of the reel for winding and unwinding of the line is attained by direct manual manipulation, and by engaging and disengaging a dog assembly which may be manually or automatically actuated and which provides a drag on the reels' rotation.

  • Patent number: 4167829
    Abstract: A line guiding tip for trolling apparatus used with a boat is shown which line guiding tip is carried by a boom extending from the apparatus and includes a mounting plug rotatably carried by the boom and a sleeve support attached thereto which carries a pulley over which passes line from a reel carried on the apparatus, over the boom through a guide over the pulley and out through a readily removable bushing carried by a bracket also mounted to the sleeve support. The bracket is rotatable in response to changes in direction of the line. Movement of the bracket to a position approximately parallel to the boom is obtained improving access to and reducing damage to the line when the end of the line is pulled aboard the boat.

  • Patent number: 4044489
    Abstract: A trolling apparatus for fishing which includes a large diameter reel mounted on a frame with a supply of line thereon which line extends to a pulley mounted on a boom connected to the frame and which may extend from the boat for fishing. The frame is mounted by a plate to a swivel base which permits the frame and boom to be swung about to desired positions without any locking or unlocking action, trolling positions being fixed by the relative motion of the boat with respect to the water and which permits the frame and boom to be locked in out-of-the-way positions when the unit is not in use, and with positive stops to prevent the base from rotation in excess of 180.degree.. The swivel base is fastened to the deck or transom of the boat and may be mounted on either side of the boat without modification.

  • Patent number: 3974589
    Abstract: A fishing line retention device for use with a trolling apparatus which detachably retains the line to the weight carried by the trolling apparatus but permits quick detachment therefrom upon a fish strike. The device includes a body attached to an arm extending from a weight with the body detachably retaining a light-weight tongue in a slot, the tongue and the fishing line being in slidable relation.

  • Patent number: 3967405
    Abstract: A line from a reel passes over a pulley and through a bracket mounted on a boom which extends outwardly from a base, the bracket carrying a bushing which can engage a stop piece on the line. The pulley is mounted on a sleeve support carried by a plug member on the boom, the support being rotatable with respect to the boom. The bracket can swivel on the pulley support and the pulley and its support can turn with respect to the boom in response to change of direction of the line.

  • Patent number: 3961438
    Abstract: A large diameter reel for a trolling line is rotatably mounted on a base with a variable drag assembly in contact therewith and with a handle rotatable in one direction for reel rotation for winding.Rotation of the reel for unwinding and winding of line with respect to the reel can be controlled by control of the drag with release for unwinding and tightening for winding so that winding of the line can be effected by rotating the handle. A shield is provided for heat dissipation from the drag.A counter is provided driven through a gear train from the reel which measures the line payout and which can be reset to zero at any time.The line from the reel passes over a wheel and bracket mounted on a boom which extends outwardly from the base, the bracket carries a bushing which can engage a stop piece on the line. The boom and bracket can both swivel in response to change of direction of the line. The bracket engages stops on the boom to limit its travel about the boom and prevent line tangling.
