  • Patent number: 6394408
    Abstract: A trolling motor column is supported in a support frame by virtue of the ball and socket connection. The column passes through the ball. The ball has a bore through which the column extends. The column may be secured in different positions to the bore or a tube which extends from the bore in the ball. The support framework houses the socket which surrounds the ball. A clutch mechanism is provided to regulate the degree of force required to displace the ball within the socket. A neutral or vertical position indicator on the ball and socket is provided to easily reposition the column to near vertical after an encounter with an underwater object. As a result, the column can flex in a multiplicity of planes around a 360° circle.

  • Patent number: 5639272
    Abstract: An improved technique for operation and assembly of trolling motors is disclosed. The direction indicator assembly is flexibly mounted to allow its initial assembly in any direction. The direction indicator can then be flexibly moved and twisted into the proper orientation where its arrow aligns with the direction of the thrust motor. If any fine-tuning is required, the direction indicator can then be turned relative to a gear mounted to it. The positioning system for the stem supporting the thrust motor includes a clutch system to avoid reverse movements of the drive system for the stem supporting the thrust motor. Fine adjustments can be made to the direction indicator, even after the thrust motor has struck a fixed object and rotated through the use of a clutching system. The clutching system is automatic and allows the continuation of steering commands to the thrust motor once the shock load that has caused the clutch to disengage is removed.
