  • Patent number: 4671385
    Abstract: A device for being attached to the distal end of a cable assembly including a tube and an inner cable extending coaxially through the tube. The device includes a body located adjacent the distal end of the tube for receiving the distal end of the inner cable, includes structure for attaching the distal end of the inner cable to the body, includes a seal located between the body and the distal end of the tube for sealing the body to the distal end of the tube when the distal end of the inner cable is attached to the body and force is applied to the inner cable to pull the body against the distal end of the tube, and includes a grease fitting attached to the body for allowing grease to be forced therethrough into the interior of the tube to lubricate the inner cable when the body is sealed relative to the distal end of the tube.

  • Patent number: 4066032
    Abstract: An electrically powered outboard motor having a water submergible electric drive member, a shaft member fixedly attached to the drive member, an attachment member for movably attaching the shaft member to a boat, and an electric circuit for allowing electrical power to selectively pass from an electric storage battery to the drive member. The electric circuit is adapted to allow the drive member to be turned so as to control the direction of the boat without causing the electrical conductor wires which allow electric power to pass from the electric storage battery to the drive member to turn with the drive member. Additionally, the electric circuit is adapted to allow the drive member to be raised or lowered relative to the attachment member without breaking the electrical contact between the electric storage battery and the drive member.
