  • Patent number: 6327830
    Abstract: A rigid body has at least one hole formed therein for receiving a piece of lumber of rectangular cross-section. The hole is rectangular in cross-section to form two long sides and two short sides of the hole, with a longitudinal axis extending through the hole. Three ribs are provided which project into the hole and extend parallel with the axis of the hole. A first rib is formed at the midpoint of one of the long sides of the hole; and a second rib is formed at the midpoint of the other one of the long sides of the hole. A third rib is formed at the midpoint of one of the short sides of the hole. An opening is formed through the one short side of the hole. When the piece of lumber is disposed within the hole in the body, a fastener such as a screw extends through the opening and into the piece of lumber to fasten the body to the piece of lumber.

  • Patent number: 6189965
    Abstract: A frame supports a fixed seat portion, and a common portion is pivoted on the frame for movement between a seat back position and a table top position. A locking device for retaining the common portion in the table top position has a manually operated end with an outer surface which is flush with the adjacent surface of a support when the device is in locked position to visibly indicate that the assembly is locked in position to serve as a table. When the locking device is unlocked, the outer surface of the manually operated end is spaced from the adjacent surface. The locking device includes wedging members adapted to be wedged between a support fixed to the common portion and the upper end of a frame member. When the locking device is in locked position, resilient arms bias projections thereon into a recess in the upper of the frame member to retain the device in position to serve as a table.

  • Patent number: 5896699
    Abstract: Three plant support discs supported by a housing and are rotated so that the intermediate disc is rotated in one direction and the other two discs on either side thereof are rotated in opposite directions so that portions of plants on adjacent discs which overlap one another move in the same direction to cause such portions to gently mesh with one another and avoid damage. A solar cell array provides electrical power for driving an electric motor which in turn drives the discs through a drive train. The discs have projections which pass through slots in gears of the drive train to provide a slidable drive connection between the discs and the gears, while the lower ends of the projections support the discs on a support surface of the housing, thereby minimizing the loading on the gears.

  • Patent number: 5018672
    Abstract: A readily portable apparatus for the size reduction of vegetable and cellulosic material is disclosed. A first shredding means having a plurality of knives is coaxially disposed with an impellar. After contacting the shredding knives the impeller directs the partially shredded material to a contacting screen or impediment which further reduces the size of the vegetable and cellulosic material. The contacting screen is pivotally movable to promote the flow of material to a discharge chute for collection. The apparatus includes means to convert the apparatus to a leaf blower and provides for attachment of a vacuum collection means. Novel safety features preventing access to moving portions of the apparatus are also disclosed and claimed.
