Summary

Description

Action of an escapement in a Linotype machine.

The keyboard has raised the escapement lever 22 to push against the plunger 11. This rotates the verge 8 which pulls down the front pawl 9, releasing the first matrix in the magazine channel. The rotation of the verge also raises rear pawl 8 to hold the second matrix.
