  • Patent number: 7243436
    Abstract: A t-bevel plumb tool configured for identifying and placing a plumb line has the components typical of a t-bevel, namely a handle and a blade that pivotally attaches to the handle, and a plumb indicator that, in one embodiment, removably attaches to one end of the blade. In this embodiment, a locking mechanism secures the blade to the first end of the handle and a plumb locking member attaches the plumb indicator to the second end of the blade during use as a plumb tool. When the plumb indicator is not being used for finding a plumb line, it attaches to an extension member at the second end of the handle. In another embodiment, the plumb indicator is incorporated into the locking mechanism that secures the blade relative to the handle and a separate level indicator is also incorporated into the handle.

  • Patent number: 6513258
    Abstract: A hand-held adjustable scribe block for aiding in the installation of trim around doors and windows includes a first body member and a second body member in a slidable relationship to each other. First body member has a generally planar engagement surface that is in a facing relationship with a generally planar engagement surface on the second body member. First body member includes a longitudinal slot disposed along its longitudinal axis for receiving a pin member to prevent rotation of the first body member relative to the second body member. A locking mechanism, comprising a screw member having an arm member attached thereto, locks the first body member to the second body member to set the longitudinal offset of the two body members. Once set, the user can utilize the scribe block to set the amount of distance the trim is set back from the door jamb or window opening. The first ends of both body members is shaped at a 90 degree angle to facilitate locating the inside corner of the door or window trim.
