Changeable type
摘要:
A changeable type element for typebars of a typewriter is disclosed comprising a U-shaped member having a pair of walls spaced from one another by a connecting type face. The type element is multipositional within the typebar segment of the typewriter. A camming means is pivotally supported between the spaced walls. A spring, attached to the camming means biases the camming means into locking engagement with the typebar when the type element is assembled on the free end of the typebar. The spring compensates for any wear on the camming means to prevent the camming means from disengaging from the typebar. The type element is thereby prevented from flying off the typebar when the typebar is in flight or from becoming loose from repeated printing operations.
