Abstract: A barrel includes a plurality of wood slats that have an inner face, an outer face and side edges, grooves formed in the edges of the slats and keys that join the slats by engaging grooves in the side edges of adjacent slats.

Abstract: A wood joint is disclosed which comprises a first heading having a first profile comprising an upper lobe, a lower lobe, and a valley section intermediate the lobes, a second heading having a second profile comprising an upper socket, a lower socket, and a ridge section intermediate the sockets, and the first profile for engaging the second profile for securing the headings together.

Abstract: A wood joint is disclosed which comprises a first heading having a first profile comprising an upper socket, a lower socket, and a flat section intermediate the sockets, a second heading having a second profile comprising an upper socket, a lower socket, and a flat section intermediate the sockets, and a spline member having a pair of tongue portions with each of the tongue portions having an upper lobe and a lower lobe, the spline member for fitting within the first profile and the second profile.

Abstract: A simulated barrel garden for aquatic and terrestrial plants comprising a circumferential sidewall consisting of two sections of vertically extending barrel staves having a plurality of straps fastening the staves together in assembled relation, a barrel liner being inserted into the sidewall and mating with the sidewall top edges and forming a rigid, stand alone half barrel supporting the weight of the garden and a water related accessory mounted on a mounting bracket and fastened to the top rim of the liner. A second embodiment includes a cascade notch in the sidewall and a mating cascade lip formed in the barrel liner. Two additional embodiments of the barrel liner include a planter ring with a shelf in the center or a hole in the center.

Abstract: A rectangular barrel having four flat sides. Each side comprises a plurality of board of substantially square cross section. Each board has right angular grooves extending laterally near the end and has a tongue on one edge and a groove on the other edge which interfit to form each side. Both end of the barrel are square with tongues extending into the right angular grooves of the boards and partially into the tongues and grooves of all the boards for sealing the ends of the barrel.

Abstract: Insulating panels or plates are formed along their opposite longitudinal edges with a cylindrically segmental projection and a cylindrically segmental groove receiving the projection, both of these formations being preferably formed as extruded polyvinyl chloride shells. The arc length of the groove is greater than 180.degree. but less than that of the projection so that the plates can be interfitted and angularly offset to fit around a vessel, the angular adjustability allowing the plates to be accommodated to greater and lesser curvatures of the vessel.

Abstract: A rectangular barrel-like structure having four wooden stave sides and two wooden stave head sections, joined together by specially designed triangular corner members. Each of the staves used in making the side walls and in making the head sections are of white oak and are of tongue-and-groove construction. Additionally, each of the staves utilized in the wall sections contains a croze at the top and at the bottom for snug engagement with the staves forming the head sections. Each of the triangular corner members is truncated at the junction of the leg and the base of the triangle so as to form a planar section equal in width to the width of the wall section stave. The truncated planar section contains a projecting tongue on one side for engagement with a complementary groove of a wall stave of one side section and a complementary groove on the other for engagement with a projecting tongue of one of the wall staves of the other wall section.

Abstract: A stave for a tub has opposite elongate edges formed with formations each having a section transverse to the stave including an arcuate portion, and a rabbet for receiving a floor of the tub extending between the edges. The formations on each stave are desirably complementary, but need not be. Staves placed in edge-to-edge relation define a tub wall which can conform to an arbitrary shape and size. A tub is formed by a plurality of staves, an appropriately shaped floor, and bands extending around the outside of the tub wall.

Abstract: A lengthwise miter joint and boards for forming it have mating effective V-tongue and -groove portions in their miter faces for positive registered alignment of the joint while it is being permanently fastened as by gluing, nailing, etc. The tongue and groove portions are centered widthwise of their respective miter faces so that the same boards may be selectively assembled either in angular or aligned relation to each other. The effective included angles of the tongue and groove provide registered angular assembly of the joint with a single rectilinear motion of one board perpendicular to the flat sides of that board. The effective V-tongues and -grooves characteristically provide relatively strong shapes to both boards in a joint.

Abstract: An improved segmented container for potted plants and shrubs of the type defining an inverted conical shape or spherical zone segment which provides greater volume of earth at the base of the container than at the top to encourage greater and healthier root growth. The container assembly consists of a base and two or more separable upper segments which are totally removeable to enable plant withdrawal with minimal damage to the root system or foliage. When assembled the container provides a leakproof, structurally functioning container capable of rapid assembly and disassembly.
