Abstract: A guide to encircle a vertically extending pile and being connectable to a floating dock to allow vertical movement of the floating dock with respect to the encircled pile, which guide comprises a plurality of individual members carrying pile engaging rollers that are releasably assembled into a closed right angle configuration with the members remaining separate and distinct from each other to change the size of the assembled guide.

Abstract: A strap corner for securing and protecting a transported load and increasing the useful life of the strap securing the load. The strap corner has side plates and a lower support to form a rigid strap corner. Rollers are provided for allowing equal tension throughout the strap during shifting of a load. A belt retainer to keep the strap and strap corner from becoming separated from the load during transport is also provided.

Abstract: A deck structure for a floating dock is comprised of a rectangular frame having opposite sides and opposite ends defined by interconnected C-shaped channel members facing inwardly of the frame and a plurality of cross members between and interconnected with the sides of the frame and constructed from C-shaped metal channel. The cross members have upper flanges spaced below the upper flanges of the side and end members of the frame, and deck units of wood material rest on the flanges of the cross members between the upper flanges of the side and end members of the frame which restrain displacement of the deck units relative to the frame in the directions between the opposite sides and opposite ends of the frame. The deck units have upper surfaces coplanar with the upper flanges of the frame, and the deck units are movable as such from the frame to provide access to passageways provided in the frame beneath the decking to accommodate utility lines and the like.

Abstract: A launching and lift assembly for small watercraft such as a jet ski comprises a skid cradle for seating the watercraft thereon for sliding movement off an end thereof. The skid cradle is mounted on a dock for rolling movement thereon forwardly over a launching edge thereof on a rear caster and on a pair of forward support rollers secured to the dock at its launching edge, for downward tilting of the skid cradle on the support rollers over the launching edge to cause the watercraft to slide downwardly off the tilted skid cradle and into the water when the skid cradle and seated watercraft are rolled forwardly on the dock to a position wherein their center of gravity is located forwardly of the support rollers.

Abstract: A door closure arrangement is provided for a paint cabinet or like enclosure containing combustible materials. Right and left hand doors are hinged to door jambs in the cabinet's opening and an overlapping lip is provided on one of the doors to insure that no gap between the doors exists when the doors are closed. Door closures, held in an open position by temperature sensitive fusible links, rotate the doors from an open to a closed position should a fire melt the fusible links. A spring biased, lever actuated door sequencing mechanism insures that the doors closed in proper sequence without interference from the overlapping lip. A spring biased, lever actuated mechanism automatically latches or locks the doors when they are rotated into the closed position whereby the adverse effects of the fire on the contents of the cabinet are minimized.

Abstract: An improved polyethylene float drum for marine structures has a preformed polystyrene core which is configured to dimensionally conform to the interior surfaces of the polyethylene walls of the drum. Because the preformed core fills the entire enclosure of the float drum, a dimensionally controlled float drum is provided with superior strength characteristics.

Abstract: Polyethylene float drums are constructed as modules, in various configurations, and then assembled into various modular systems to float a variety of structures. All float drum modules utilize at least one flat, perpendicular side wall to insure accurate assembly of the float drum modules into a flanged load bearing modular float assembly having desired float characteristics.

Abstract: A floating dock having individual dock sections pivotally interconnected by continuous metal hinge connectors to permit relative vertical pivoting movement between adjacent dock sections. The hinge connectors each comprise a pair of elongated metal hinge leafs pivotally interconnected by a pivot pin extending through aligned hinge loops on the hinge leafs. The hinge connectors are secured to adjoining spaced, parallel, portions of the respective dock sections with their pivot pins extending horizontally and lengthwise of the spacing therebetween and with the hinge leafs and their hinge loops bridging and closing the gap between the spaced dock sections at the level of their deck surfaces to form continuations thereof. The hinge leafs are preferably formed with depending side anchor leg portions for securing them to the dock sections, and their hinge loops are preferably located on their underside.

Abstract: A pipe flotation assembly, packageable in kit form, includes interfitting interconnected frame members having flotation devices secured to the bottom thereof and an adjustable clamping assembly for securing a wide variety of pipe sizes.
