Abstract
A gap is provided between two teeth on a power roll in a typing machine repeat key action, and a cam follower surface is provided on a repeat interposer. A repeat typing operation can be initiated only when the cam follower surface engages the gap. When the key action is not in a repeat position, a latch and a forked lever cooperate to hold the repeat interposer away from the power roll; when the key action is in the repeat position, the forked lever holds a single-action interposer out of the way. The gap prevents skipped and uneven repeat typing operations during high-speed operation by giving the actuator and the typebar enough time to settle into rest position.
