Abstract: A dry-wall cutting tool is described. It has a block-like configuration and is designed to slide over the edge of the drywall and to cut both sides of the drywall to the same distance from the edge and at the same time as it does so. The depth of the cut (i.e. distance from the edge of the drywall being cut) can be controllably varied considerably and it will typically be between 1/8 inch and 6 inches deep from the edge of the drywall that is being cut. The cutting tool has vertical threaded shafts upon which are mounted cutting wheels and rubber or nylon rollers, with ball bearings between the shafts and the cutting wheels and rollers. Due to its construction the twin cutting can be done quickly and with little manual effort or force.

Abstract: The invention relates to an improved shell-type pickup truck cap having a means for preventing damage to the cap when it is being installed on, or removed from, the bed of a pickup truck, or when said cap is being transported to or from storage. The cap comprises a substantially planar top, longitudinal sidewalls and a rear wall of a substantially inverted U-shaped configuration, which typically is or includes a hatch. An elongated support, or spacing bar, is provided to be rigidly positioned across the opposite internal bottom portions of the sidewalls. The support bar is suitably detachably secured to the bottom rear portions of each of the sidewalls to span the distance between the sidewalls and to substantially prevent inward or outward movement of the sidewalls. In this manner damage to the upper rear of the cap is prevented while the cap is being installed on, removed from, a pickup truck bed, or while the cap is being transported to or from storage.
