(under subclass 365) Subject matter wherein the typewriter is driven by a power drive that includes said shaft and a second shaft, which second shaft is rotated intermittently (i.e., when an operation is to be performed), and has radial projections thereon one of which projections strikes a member when the second shaft is rotated, which member is moved substantially tangentially of the second shaft when struck, and which member lies between the second shaft and a linkage that actuates the operation to be performed.
(1) Note. The operation that is performed is usually the selection of a type-face* to be impacted against the record- medium* and the actuation of the type-bar* that carries the selected type-face.
