    • 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.
    • 为具有高摩擦系数和低摩擦系数的各种工具提供设备。 具有低摩擦系数的材料可以安装在工具上并且具有垂直于工具的运动。 该垂直运动可以用弹簧机构来实现。 具有高摩擦系数的材料可以以固定的位置安装在工具上。 工具可以被压靠在表面上,首先以低摩擦系数接合材料。 该工具可以自由地移动穿过表面,而具有低摩擦系数的材料保持与表面接触。 随着工具被不断地压向表面,具有高摩擦系数的材料随后与表面接触,从而导致工具相对于表面的横向移动被限制和稳定。 工具的一个例子可能是精神或木匠级别。

    • A level is disclosed with a sliding measurement system. The level includes a planar upper surface, a planar lower surface and a web extending between the upper surface and the lower surface. The web includes at least one elongate channel to which a track having an inwardly facing slot is mounted. The level further includes one or more pods slideably received on the track in the inwardly facing slot. The pod includes a generally cylindrical female member having upper and lower ridges extending outwardly therefrom, and a generally cylindrical male member configured to receive a marking instrument, the male member being matingly received in the female member. The upper and lower ridges of the female member are configured to be received in the inner slot of the track and are slideable thereon. The level further includes at least one bubble level vial mounted to the web of the body of the level.
