Abstract: A vertically movable cantilevering type gate is disclosed. All that is required is an elongated cylinder mounted vertically and a piston rod slidably mounted therein. The piston rod is mounted for vertical movement in the cylinder and suitable laterally spaced vertically movable guides are provided to maintain the gate in alignment with the gate opening. Preferably a channel shaped cap bar is positoned to overlie a trough into which interconnected link members are adapted to fold. The link members support laterally extending mesh type closure members which close the gate opening when the gate is elevated. The gate is controlled by a water pressure operated system. The valves controlling the flow of pressurized water to actuate the gate are controlled electrically. In one desirable construction when no electric power is applied, the valves direct water under pressure to urge the piston rod upwardly in the cylinder to maintain the gate in the obstructing or closed position.

Abstract: As the land becomes more populated due to the land being subdivided into smaller tracts the need for barriers to indicate the boundaries of the individual property holdings increases. In many instances it is no longer necessary to provide a fence tight closure as was previously considered necessary to confine small animals such as chickens, pigs etc. As the cost of erecting and maintaining fence tight types of gates has increased during recent years many people have realized that all that is required is a barrier to indicate the extent of individual property holdings. I have devised a versitile type of barrier that can be manufactured economically, and can be maintained in service at low costs.

Abstract: A boat lift mounted on a plurality of spaced masts secured in suitable foundations are provided to support an equal number of spaced rails extending angularly into the water to a depth below the draft of the boats to be elevated on the boat lift. A plurality of boat carriers slidably mounted on the rails have spaced rollers engaging the flanges of the rails to facilitate movement of the boat carriers relative to the rails. The boat carriers have horizontally extending extensions secured to their lower ends to underlie the boat which is chocked to hold it in an upright position on the boat carrier extensions as the boat is moved out of the water. A winch housing having a power actuated winch therein is provided to wind up a cable secured to the boat carrier to pull each of the carriers and the boat on the carrier extensions up the rails to elevate the boat out of the water.
