Spirit level liq. container holder for web mounting - has easy assembly base extended into annuli at ends

摘要

A liquid bubble container for mounting on a web of a machined or cast spirit level body is designed for economical non-labour intensive construction of high quality levels by eliminating unnecessary intermediate assembly processes. The lower part of a flat base section (1) is connected to the web (2) and is extended at its ends by two parallel identical arms (8) ending in transverse annular sections. The centres of the transvers annular sections are coaxial and offset w.r.t. the base section. The base section has a hole enabling it to be screwed to the web whilst the annular sections have outward projecting stops resting against the opposite side of the web. The bubble section (10) fits inside the two annular rings (8).
