Abstract

Platen knobs for typewriters are conventionally secured to the platen shaft by set screws which often become loose as the typewriter is operated. The device illustrated in the drawing is designed to secure the platen knob to the platen shaft while inhibiting its tendency to become loose during typewriter operation.
