ABSTRACT:
A mechanical pencil having a cylindrical barrel (1) and a sheath (2) in axial relationship is disclosed. 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). When the writing unit is in its protruding position the push-type feed mechanism is activated by forcing the sheath (2) forward, closing the gap between the barrel (1) and the sheath (2). An inventive pocket clip is provided which may be lockingly engaged flush with the surface of the sheath (2) or which can be raised into an in-use position by activating a high tension spring. In use, the forward portion (38) of the clip is forced away from the surface of the sheath by applying leveraging force. This allows clothing material to be frictionlessly positioned between the clip and the sheath surface.
