Abstract
Mécanisme d'échappement pour machine à écrire à boule. Le chariot de la machine est entraîné par une vis-mère 14 solidaire d'une roue à rochet 32 dont le cliquet 31 est dégagé au moyen d'une tringlerie actionnée par l'arbre de commande d'impression lors de l'enfoncement d'une touche. Afin d'empêcher l'échappement, la tringlerie en même temps qu'elle dégage le cliquet 30 engage le cliquet 41. Lors du retour de la tringlerie en position de repos, le cliquet 41 libère la roue mais celle-ci n'échappe que si léélectro-aimant 33 a été excité pour dégager le cliquet de la roue.
