ABSTRACT:
A writing implement is provided having a body comprised of a pencil end-segment and a pen end-segment. Slideably mounted within the pencil end-segment is a carriage member having a tubular holder for receiving the inner end of a length of lead. The carriage member is provided with a cantilevered arm having an arcuate outer edge which normally bears against serrations provided on the inner wall of the pencil end-segment to effectively lock the carriage member in position. The carriage member can be released and slideably moved to feed the tip of the length of lead for writing by depressing a button on the end of a stem which extends through a longitudinal slot in the pencil end-segment and serves to free the arcuate outer edge of the arm. The pen end-segment, which is threadably detachably connected to the pencil end-segment, encloses a replaceable unit including a magazine for ink and a ball point writing member. An end cap is provided which can be positioned over either the ball point end or the lead end of the body.
