Restoration of a Portable Kymograph

Résumé

The presence of an old portable kymograph in the Phonetics and Phonology Laboratory (LPP) of La Sorbonne Nouvelle gave the idea for a restoration project. Alexis Rygaloff purchased a portable Gauthier kymograph for field investigations in China around the middle of the 20 th century. The kymograph (about 10 kg) consists of a recording cylinder moved by a clockwork mechanism associated with a Foucault regulator. The clockwork mechanism is connected to a drive bar by means of a belt placed on two wheels, one connected to the mechanism and the other to a drive bar. The registering devices (Marey's drums) built by Verdin are attached to a trolley fixed on a foot connected to the bar. The regulator allows to choose different movements (slow, medium, fast) depending on the nature of the experiments that are planned.
