  • Patent number: 4089180
    Abstract: The invention relates to a floodgate for use with an earthen levee having a cut therein. The floodgate includes a generally rectangular piece of sheet material having sufficient dimensions to cover the area of the levee defining the cut when the floodgate is in its water-passing position. The floodgate further includes an elongated relatively rigid pole having a length greater than the width of the cut in the levee. A loop is formed in the piece of sheet material along one end thereof, generally across the width thereof, and having a void area encompassed thereby at least as great as the cross-sectional area of the pole so that the pole may be received by the loop, and so that the pole may be rotated to wrap the sheet material around the pole while the pole is received by the loop. Preferably, the sheet is polyethylene having ultra-violet inhibitor, about 14 to 16 mils thick, and about 9 feet by 4 or more feet.

  • Patent number: 4019703
    Abstract: A safety mount for a trolling motor including a clamp for attachment to the stern of a boat, a hollow mounting block pivotally mounted to the clamp, a detent arrangement disposed within the interior area defined by the block and for normally maintaining the block in abutting relationship with the clamp (the trolling motor being in operative position in the water), and a latch for latching the motor out of the water. The detent arrangement is so constructed that if the motor strikes an underwater object, the block will be pivoted with respect to the clamp and move the motor out of engagement with the object. Once the object is passed, the weight of the motor will move the block back to its normal operating position. The motor may be manually pivoted out of the water, and the block latched so that the motor remains in its inoperative position.
