Abstract (en)
[origin: WO8402773A1] A slope indicating device or "level" having an arcuate angle indicating scale (7) arrayed about a central axis (12) on a reference member (1) having a straight edge (3) adapted to be aligned with a slope. A bubble tube (16) is located against the angle indicating scale (7) on a level indicating member (9) rotatably mounted on the reference member (1) about the central axis (12) so that the bubble tube may always be aligned and/or read against or adjacent the angle indicating scale. In the preferred embodiment the arcuate angle indicating scale is on a transparent toroid (5) which surrounds the bubble tube (16), and an annular housing member (10) is provided, encasing the toroid, keyed to and rotating with the level indicating member, and provided with a viewing window (14) aligned with the bubble tube (16).
