    Abstract: An improved and strengthened wide board composed of multiple edge joined narrow boards for use in commercial and residential construction is disclosed. These wide boards are typically used for purposes such as shelving, stair treads, or other purposes where they may be appropriate. The improved wide board is made by drilling or boring holes from edge to edge through the width of each narrow board, with the exception of the leading narrow board in each wide edge joined board, in a manner that accommodates screws or fasteners, which act to securely clamp or pull the boards together. These holes are step-drilled in a manner that allows the head of the screw or fastener to be recessed below the edge of the narrow board, in order to attain a smooth or flush surface between boards. The hole then steps down to a smaller diameter to accommodate the shank of the screw. A screw may then be inserted in a manner that its shank end exits the hole and “bites” into the edge of the next adjacent board.

  • Patent number: 6389774
    Abstract: Methods, apparatuses and systems directed to joint restraining systems for concrete constructions. In one embodiment, the present invention is a novel method for creating joint restraints that employs a pipe dowel. As more fully described below, the present invention substantially reduces the time and labor involved in tying a series of parallel dowels into a rebar matrix. For example, the present invention eliminates the need to cut out sections of rebar. Rather, embodiments of the present invention require only a single cut in each rebar section along the line of the intended joint, rather than two cuts to remove a section of rebar. The present invention also eliminates the time and effort associated with tying dowels into the rebar matrix. In another embodiment, the present invention is a novel pipe dowel mechanism that, in addition to the advantages described above, obviates the need to apply a messy protective coating, such as grease, to a smooth dowel.

The first end-cap, for example, can be a single component extending across the lower ends of the stiles and a bottom surface of the bottom rail. The door more preferably includes a first moisture-resistant end-cap attached to the first lower end of the first stile and a separate second moisture-resistant end-cap attached to the second lower end of the second stile.

  • Patent number: 6167670
    Abstract: A system for building shaft casing for dumb-waiters in a building structure with prefabricated assemblies that are readily stackable over each other. One lower, middle and top assemblies constitute the minimum combination typically used in going from one floor to the next. However, the middle and upper assemblies can be repeated depending on the structure where the system is installed. The assemblies include each four elongated corner members with respective ends that receive connecting pin members that permit the structurally stable stacking up of the assemblies. A central and continuous passage is defined. The lower assembly includes two apertures with adjacent compartments within the central passage one to have access to the dumbwaiter and the other one to access the motor and control means. The top assembly has an aperture to provide access to the sprocket mechanism used with the chain that suspends the dumbwaiter within the shaft casing.
