    Abstract: An automatic lead pencil device has a casing which is releasably mountable in a bracket of a drafting machine. Within the casing, there is a clamp sleeve in which a clamping member is axially movable for clamping and releasing a lead during use of the pencil device. An axial movable lead guide tube projects outwardly of the casing in the rest position, and there is a pencil brake within the lead guide tube. The contact zone between the clamping member and the clamp sleeve is constructed so as to be of the non-self-locking type. There is an operative connection between the clamping member and the lead guide tube such that the clamping member is closed when the lead guide tube moves axially inwardly to assume the working position and opens when the lead guide tube moves axially outwardly toward a rest position.

A spiral member (4) in fixed relationship with the sheath and in axially sliding relationship with the barrel for a predetermined range engages a slider (7). The slider is in fixed relationship with a push feed type writing unit and slides axially within a predetermined range within the barrel (1) as allowed by a guide (3). First spring means is provided to urge the spiral member in a forward direction when the writing unit is positioned axially such that it is contained within the barrel (1). As the writing unit is moved from its rearmost position within the barrel (1) to a protruding position by rotation of the spiral member (4), a second spring means urges the spiral member in a rearward direction, forming a gap between the barrel (1) and the sheath (2).
