Read Explanation:
The Escapement Mechanism
The movement of the typewriter carriage is a fundamental mechanical principle governed by the escapement mechanism, which relies on these three main parts working in conjunction:
Carriage Rack (Rack): This is a long, toothed bar attached to the bottom of the typewriter carriage.
Pinion Wheel: This small gear meshes directly with the teeth of the carriage rack. It translates the horizontal movement of the carriage into rotational movement.
Escapement Wheel (often called the Starwheel): The Pinion wheel is often connected to this wheel, which is controlled by the escapement mechanism's dogs (pawls).
