Outrigger for scaffolding

In combination with a scaffold which includes at least four generally vertical members each establishing a respective corner of said scaffold, first and second generally parallel horizontal members, said first generally horizontal member spanning and being connected to first and second of said generally vertical members, said second generally horizontal member spanning and being connected to third and fourth of said generally vertical members, said scaffold being of a generally polygonal configuration as viewed in plan with said polygonal configuration being defined by four vertical planes spanning said first and second corners, said second and fourth corners, said third and fourth corners and said first and third corners, and at least one generally horizontal plank spanning and supported by said generally horizontal members, the improvement comprising means for supporting a second generally horizontal plank positioned in generally side-by-side relationship to said one plank at an end portion of said second generally horizontal plank appreciably outboard of said polygonal configuration in the direction of the length of said second horizontal plank, said second plank supporting means including first and second generally parallel horizontal arms, a first of said arms having means at one end thereof for removably connecting said first arm to one of said vertical members and underlyingly supporting said second horizontal plank, said first arm lying generally parallel to the most adjacent of said four planes which is normal to the direction of the length of said second plank, said second arm being appreciably spaced from said first arm and in underlying supporting relationship to said second plank at a point most adjacent a free edge of said second plank, and cantilever arm means for cantilever-supporting said second arm from said first arm appreciably outboard of said most adjacent plane in a direction normal thereto.
