  • Patent number: 7013825
    Abstract: A jack plate (9) moveable upwardly and downwardly between various positions has a trim tab (28) disposed on a fixed portion (10) of the jack plate near the base of the transom (11) of a boat. The moveable portion (12) of the jack plate has a push cap (44) that, at a pickup position of the jack plate, pushes a rod (43) which rotates a lever (38) to move an arm (33) to push the trim tab (28) into an operative position aft of and below the hull of the boat. Above the pickup position, the push cap does not contact the rod; a return spring (50) causes the trim tab (28) to rotate upwardly, into a position where it is ineffective.

  • Patent number: 6923136
    Abstract: A trim tab (18, 204) hinged (19) at the bottom edge of a boat transom (12, 179) is rotated into a position below the boat when the drive (58, 186) is in a lowest-most trim position, and is raised up, when the drive is above a selected pickup trim position. A push tube (58) connected to the motor (16) operates a push rod (49) and a trim tab (18). A push bar (96, 97) is moved by the drive, causing pieces (104, 105) to rotate trim tabs (18a). A fluidic slave cylinder (142) is operated by a master cylinder (134) or by a pump (148) responding to a position detector (150). Levers (164, 167) may be connected by a cable (155). A hydraulic master cylinder (195) is disposed on a part (186) of an outdrive that rotates for trim, its cylinder rod (200) contacting a fixed part (184), driving fluid to a slave cylinder (201) mounted on a fixed part (183) with its piston rod (202) moving a trim tab (204).

  • Patent number: 6767324
    Abstract: An epicardial cooled stabilizer system is useful for surgical or laparoscopic applications, especially beating heart surgery. The system comprises a stabilizer connected to a cooler/pump where coolant flows into tubing at the distal end of the stabilizer. The tubing is positioned at a surgical site to enhance traction and minimize trauma.

  • Publication number: 20020083635
    Abstract: In a method of fishing utilizing the flippin technique, a loop of line is drawn from between two eyelets, rather than from between the reel and an eyelet. A flippin rod (10a, 10b) has an additional eyelet (27) mounted between the reel (13) and the closest guide (19) of a plurality of conventional eyelet fishing guides (16-19). Fishing utilizing the flippin technique with the rod (10a, 10b) includes grasping the line (21) between the guides (19, 27) and pulling the line into a loop (29). The eyelet (27) prevents the loop (29) from tangling with the reel (13) when the loop is released, and also provides additional line (31) so the bait will achieve a deeper depth. In a telescoping rod (11b), the eyelet (27) is positioned so as not to interfere with retracting the distal portion (34) of the rod (11b) into the proximal portion (33).

  • Patent number: 6273020
    Abstract: A restraint for holding fishing poles to the deck of a boat includes an anchor screwed to the deck, a unidirectional snap fastener having its base portion screwed to the deck, and a double strand of bungee cord or other resilient strand extending from the anchor to a cap of the snap fastener. The unidirectional snap fastener is oriented so that no amount of force pulling up on the bungee cord will release the snap fastener, but a slight tug on a side of the snap fastener opposite to the anchor will easily cause it to release. The cap of the snap fastener includes a looped tab to facilitate separating it from the base. The anchor may be secured in the end wall of a hatch cover; the snap fastener may be secured adjacent to a gunwale.

  • Patent number: 5515641
    Abstract: A fishing pole casing consists of a tubular sheath of plain or canvas backed, smooth, solid plastic sheeting with a longitudinal, stitched or welded seam, and an elastic loop; only the portion of the rod ahead of the reel is inserted into the sheath and the elastic loop engages the reel of the pole to urge the rod into the sheath.
