Abstract: A boat trailer is equipped with a powered boat launch and retrieval system that negates the shallow entry of a launch ramp. The system uses a weldment frame, pivotally connected to the trailer frame. The weldment frame works in combination with a powered cylinder, gravity's effect on the weldment frame and the hull of the boat to automatically release the boat into the water or automatically retrieve the boat from the water.

Abstract: The following specification discloses a boat trailer equipped with a powered boat launch and retrieval system that negates the shallow entry of a launch ramp. The system consists of six main components. 1. A custom bow eye. 2. A damping push/pull bar. 3. An “A” frame weldment with pivotal (base) ends attached to the trailer, and pivotal forked (apex) ends bilaterally positioned over the bow eye, to support the bow load, through the damping push/pull bar. 4. A dual purpose pneumatic cylinder of size and length to power the “A” frame weldment aft to the buoyancy position and also to control the forward gravitational descent of the bow back to the towing/storage position. 5. A removable two piece triangular yoke to facilitate retrieval and containment. 6. A retrieval winch of sufficient size to retrieve items one through five of the above, back to the towing/storage position.

Abstract: The disclosure herein sets forth an equipment shock mounting means for utilization with a container formed of plastic. The shock mounting means comprises a rigidified outer frame structure which can be formed as a portion of the edge regions of said container portions. The edge regions of the container portions can be formed with channel members which are suited to match each other so that when they come together they form a complete closure. Attached to the channel members are shock mounts extending interiorly and supporting an equipment shock mount structure for equipment to be mounted thereon. As an alternative, the edge region channel members can be substituted for mounting the shock mounts in the way of a frame member. The shock mounts extend inwardly to support the equipment shock mount means and receive equipment thereon.

Abstract: The following specification discloses a container such as a box, packing or shipping container for items that are to be maintained in a vapor proof environment. The container is made out of a sheetlike material, such as plastic derived from one of the olefin family of plastics. It is formed with bumpers, guards, and reinforcing and expanded portions of the case for protection and reinforcement thereof. The sealing and closure means comprise a pair of channel members that are secured over the edge of the walls of the container. One of the channel members provides an elongated depressed seat for an elastomeric seal therein, and the second channel member provides a mating tongue that seats against the elastomeric seal. Both of the channel members are hinged, latched or clamped together with the edge regions of the container walls lying within the channels. The channels have barbs or tangs which impinge against the container wall portion.

Abstract: A jet drive boat propulsion unit cover for purposes of covering the fluid intake of a jet powered boat. The cover accommodates itself to the intake opening including the grillwork thereof, in a manner whereby it covers and seals the intake from foreign objects which might contaminate and adversely affect the wear and operation of the jet power unit, such as the impeller, bearing surface, and other wear areas. The cover is secured by means of an overcenter latching linkage having a member that moves eccentrically around an axis to cause a hook to engage the grating or grillwork of the opening so that it can be easily latched and unlatched. The foregoing provides a generally sealed relationship around the edges of the opening to prevent the migration of foreign matter into the jet drive unit.
