Abstract: A fish lure is disclosed comprising a body or plug used to simulate fish bait in which a retractable hook or plurality of retractable hooks are mounted. The hooks are released from a retracted position to an extended position when the lure is drawn through water. This is achieved by mounting a shaft slideably within the body of the lure and securing the hooks to the shaft. A trigger is provided on the lure which engages the shaft to hold it in a position such that the hooks are pulled in towards the body of the lure. When the trigger is released by pulling the lure through the water, a resilient member biases the shaft in a direction to allow the hooks to swing freely from the body of the lure. The trigger comprises a sear having a diving plane on one end thereof, the sear being pivotally secured to the body of the fish lure and which releasably engages a stop on the shaft.

Abstract: A bolt mechanism of the disclosure has a bolt driven between latching and non-latching positions by a rotary electric motor through a speed reduction gear drive train which includes a slip clutch that permits the bolt to be manually moved from either position thereof to the other in a manner overriding the drive train and the motor. The electric motor is of the DC type, and an electrical control circuit therefor reverses polarity and terminates the motor operation as the bolt moves to either of its positions so that subsequent normal motor operation is in a reverse direction to drive the bolt to the other position. A recess in the bolt receives an output gear of the drive train as well as an elongated gear rack fixedly mounted with respect to the bolt and meshed with the output gear to provide the bolt movement during motor operation. A handle mounted on the bolt is manually grasped to provide the overriding movement of the bolt.
