Abstract

Referring to the figure, the first cycle of a repeat operation is done the same as a single cycle by the dobber 10 engaging and depressing the interposer 12, so that the latch 14 trips the cycle clutch bail. When the first cycle is completed, the dobber 10 is out of the way of the interposer 12.

Repeat Keys for Serialized Keyboard

Referring to the figure, the first cycle of a repeat operation is done the same as a single cycle by the dobber 10 engaging and depressing the interposer 12, so that the latch 14 trips the cycle clutch bail. When the first cycle is completed, the dobber 10 is out of the way of the interposer 12.

As the key lever 16 is depressed further, the repeat lever 18 reaches a down- stop 20 and then pivots about the point of contact. The tip 22 of the repeat lever 18 pushes the key lever restore spring 24 which, in turn, engages the extension 26 on the interposer 12 pushing it down to the trip level.

As the repeat lever 18 engages the down-stop 20, the further depression after that causes the wire form spring 28 to deflect by moving away from the key lever 16, hence providing the incremental repeat load.
