Abstract

A mechanical marking pen is disclosed. The marking pen includes a cylinder and a holder element axially and movably engaged with one end of the cylinder. A pen point is removably attached to the cylinder and is slidably fitted concentrically in the holder element so as to project from the holder element to permit a length of projection to be adjusted. There is an ink reservoir contained in the cylinder for storing ink. An ink guide core is provided to connect the pen point and ink reservoir to allow the transfer of ink to the pen point. There is an element concentric with the pen point, for receiving and transferring writing pressure from the pen point. Finally, an element is mounted concentric with the pen point and is engaged with the receiving and transferring element. This element accepts writing pressure from the transferring means to prevent the ink guide core from bearing pressure from the pen point.
