Abstract
A reversible drive for a fish-finder apparatus includes a motor, a drive gear driven by the motor, a driven gear driven by the drive gear and a fish-finder drive shaft driven by the driven gear. The drive gear contains one or more actuator members which actuate a drive control member, such as a reverse polarity switch, during rotation of the drive gear. When actuated, the drive control member reverses the drive to the motor and thereby reverses the drive to the fish-finder. A display panel contains diode indicators which are illuminated in response to the movement of the fish-finder.
Claims18
A fish finder having a reversible drive assembly for driving a sonar transducer in a preselected pattern, comprising:
- a sonar transducer;
- means for mounting the transducer to a boat, the mounting means including an elongated mounting member having said transducer mounted therein, said mounting member holding said transducer at a predetermined elevation with respect to the boat, said mounting means further including a housing which rotatably receives said a portion of said mounting member therein;
- motor means for supplying rotational drive to said sonar transducer;
- a gear train interconnecting the motor means and the transducer, the gear train transmitting rotational drive from said motor means to said transducer, said gear train including at least a drive gear and a driven gear, the drive gear being operatively connected to said motor means in a manner such that said motor means supplies rotational drive to said drive gear, the driven gear being operatively connected to said mounting member, said drive gear and said driven gear operatively engaging each other such that said drive gear supplies rotational drive to said driven gear and said sonar transducer;
- means for reversing the drive supplied by said motor means to said gear train whereby rotation of said sonar transducer is reversed;
- and,
- means for actuating said drive reversing means, the actuating means being operatively connected to said drive gear.
A reversible drive apparatus for a side-scan sonar transducer or the like, comprising, in combination, a housing for attachment to a boat, the housing containing a drive motor, a first gear operatively connected to said drive motor and driven thereby when said drive motor is energized, a second gear operatively connected to a sonar transducer drive shaft, the second gear operatively engaging said first gear, the second gear being driven in rotation by said first gear when said first gear is rotated, means for reversing the drive supplied by said drive motor to said second gear, the drive reversing means including an actuator component repositionably disposed on said first gear and rotatable therewith, a switch component which reverses current supplied to said drive motor to thereby effect reversal of drive of said motor, said switch component being disposed in the path of rotation of said actuator component such that said actuator component contacts said switch component during the rotation of said first gear and trips said switch component to reverse the current supplied to said drive motor and thereby reverse the drive of said drive motor, first gear, second gear and sonar transducer, said reversible drive assembly further including means for visually indicating rotation of said sonar transducer, the visual indicating means being operated by movement of said second gear.
