Class Information
Number: 400/144.2
Name: Typewriting machines > Including type-set-assemblage mounted on carrier and relatively movable for selection and for impact of type-face > Including type-faces movable relative to type-face-carrier > Type-face-carrier including type-faces on flexible arms > Rotatable or oscillatable carrier > Carrier having coplanar flexible arms (e.g., "daisy" wheel, etc.)
Description: Subject matter wherein the type-face carrier* includes the plurality of resilient members, and wherein the members extend radially from the axis of the carrier in substantially the same plane, and each member, and the type-face* element supported thereby, oscillates in a second plane that is coincident with said axis.
