Abstract: Apparatuses are provided for various tools that incorporate materials with a high coefficient of friction and a low coefficient of friction. The materials with a low coefficient of friction may be mounted on a tool and have a perpendicular movement to the tool. This perpendicular movement may be implemented with a spring mechanism. The materials with a high coefficient of friction may be mounted on the tool in a fixed position. The tool may be pressed against a surface, first engaging the materials with a low coefficient of friction. The tool may freely move across the surface while the materials with a low coefficient of friction maintain contact with the surface. As the tool is continually pressed to the surface, the materials with a high coefficient of friction subsequently make contact with the surface, thereby causing the lateral movement of the tool with respect to the surface to be restricted and stabilized. An example of the tool may be a spirit or carpenter level.

Abstract: An improved framing square having integral features for automating the marking and cutting of angles. The square contains two sliding carriages—one in the body and one in the blade. Each carriage has a deployable pin. In order to set an angle, the user first deploys the pins in each sliding carriage so that they protrude downward from the square. Next, the user sets the sliding carriage in the body to the desired position and locks it in place. The user then sets the sliding carriage in the blade to the desired position and locks it in place. The two pins protruding from the sliding carriages are then butted against the board to be cut. Once they are in place, the blade of the square will form the correct cutting angle across the board. Since many common cuts employ a twelve inch base leg, the invention includes another feature: Rather than set the sliding carriage within the body to twelve inches, the user may opt instead to deploy a fixed pin located in the body at the twelve inch position.
