Coulter Thrasher Frog

This invention is for a lure for fishing more particularly an animated plug type wherein appendiges are actuated during a cast as the lure is moved through the water to simulate a living creature.

It has heretofore been proposed to provide fishing lures with rubber band powered motors to propel the lure through the water. According to the present invention a rubber band powered motor is used to actuate leglike appendages to produce motion in them intended to attract game fish.

One difficulty with the use of casting plugs using any kind of simple motor such as a rubber band type of motor is the fact that these motors tend to unwind very rapidly, so that when such a device is used in a plug, it may rapidly expend its power while the lure is being cast, and the action will be uselessly spent before the plug ever hits the water. The elements of simplicity and size of the plug do not make it practical to use conventional types of governors, or geared spring-driven motors.

An important object of the present invention is to provide a lure using a rubber band powered motor with simple and effective means for preventing free spinning of the driven part so that little action takes place during the cast and the driven part turns slowly when the plug is in the water.

This means is expendable and may require replacement from time to time, and a further object of my invention is to provide a lure in which this part or the rubber band may be readily replaced. A further object of my intention is to provide a lure which provide a unique action in the water.
