Object number: NG-MC-811

Model of an optical telegraph, mounted on a square base.

The model consists of double-shored poles with an operating mechanism at the base and moving arms at the top. The main arm turns on an axle between the poles and has two wings attached to the ends, which can turn separately from one another. The operating mechanism mimics the movement of the arms and the movement is transferred by means of chains on the axles of the moving parts.

The model is first mentioned as part of the private collection of Jochem Pietersz Asmus (1755-1837) in 1807.³³HNA 2.01.29.02 Dept. Marine, Aanhangsel I, inv. no. 20, La. F no. 1. Claude Chappe’s (1763-1805) telegraphs were used in France from 1792 until the introduction of the electric telegraph in 1844. Between 1810 and 1813 there was a line between Paris and Amsterdam.

This model is a so-called ‘Milan configuration’ type; the operating mechanism and transfer of movement incorporates improvements of Chappe’s design, as suggested by Abraham-Louis Bréguet (1747-1823).

Scale unknown.
