A device for receiving a writing implement has a housing, a resiliently yieldable sealing member in the housing and adapted to sealingly abut against a writing tubular member of the writing implement, and a wetting member in the housing and located in spaced relationship with a pressure-equalizing passage of the writing implement as well as communicating with the passage. The resiliently yieldable member may be composed of two axially movable balls which are received in a cylindrical portion of the housing and axially limited by two axially spaced collars. The cylindrical portion may be connected with a conical extension which, in turn, may be connected with a further cylindrical portion received in the receiving opening of the housing. These portions may be of one-piece with each other so as to form a one-piece insert member.

Device for receiving a writing implement

A mechanical pencil has an axially elongated hollow pencil body in which is slidable a tubular seat member. A lead-protecting sleeve is axially displaceable in the pencil body between a front position and a rear position and is urged into the front position with a relatively strong spring force. At least two jaws are axially displaceable on the seat and are moved radially closer as they move backwardly from the tip so as to grip a lead that projects backwardly from the lead-projecting sleeve. A relatively weak spring urges these jaws backwardly in the seat. An O-ring is provided in the lead-projecting sleeve so that each time the pencil tip is lifted from the writing surface the lead is automatically pulled forwardly by the strong spring force through the jaws. Similarly forward displacement of the seat in which the jaws rest allows for manual advance of a lead gripped by the jaws and passing through the lead-protecting sleeve.
