Small Chrome Barograph by Léon Maxant


Early 20th century small French chrome barograph signed LM for Léon Maxant.

A barograph, or recording barometer, records the movement in barometric pressure over time. The papers are fixed to a revolving drum containing a clock mechanism – this drum rotates over the course of one week. A barograph makes an interest ornament for a scientist, or indeed anyone interested in the weather.

The chrome-plated case has a hinged lid fitted with bevelled glasses, the whole piece being in exceptionally good condition – so good in fact that we initially thought it had been recently re-plated.  The lid is effectively locked shut by a heavy sprung button to the left. The base is stamped with Leon Maxant’s trademark, L M either side of an anchor, and stamped with serial number 327834.

The barometer mechanism with 4 vacuum capsules, the recording arm fitted with a fibre tip nib.

The 8-day clock movement is contained within the recording drum, and is key wound with the original separate chrome key. The movement is overhauled and guaranteed for 3 years.
