  • Optical Vertical Plumb Measuring Device
    Publication number: 20130047450
    Abstract: A tool for projecting a light beam along a vertical surface for the purpose of determining any deviation of that surface from the true vertical, but wherein the light beam is spaced horizontally away from the vertical surface to avoid interference from projections formed in the vertical surface. The tool comprises a light projecting component and a separate, hand held target component upon which projected light impinges. The light projecting component may comprise a linear measurement scale enabling the user to determine the displacement distance of the light projector from the vertical surface. The target component comprises a corresponding linear measurement scale. When light is emitted vertically and strikes the target, measurement readings from both measurement scales are read to determine any discrepancy of the top of the vertical surface from vertical registry with a lower point along the vertical surface at which the light projector is located.

  • Furring and fireproofing protection clip assembly
    Patent number: 3998028
    Abstract: A clip assembly for attaching a member, such as a partition or duct, to a support covered with a layer of a fireproofing material while maintaining the integrity of the fireproofing layer, or attaching wallboard to a beam or column, has a pair of clip sub-assemblies adjustably connectible together to fit different size supports. Each clip sub-assembly is provided with a plate portion defining a planar support engaging surface substantially in the form of the outline of a right triangle and arranged particularly for gripping a flange of an I-beam and the like, while end walls perpendicular to the plate portions facilitate attachment of wallboard to the clip assembly for furring, and the like. Base portions, one of which has a slot and the other a plurality of spaced openings mateable to the slot, are connected to the plate portions and permit the adjustable connection of the clip sub-assemblies to various size supports.
