DRAWING CONICAL BODY WITH FALLING WEIGHT FOR INDIAN INK FOUNTAIN PEN

摘要

An India ink drawing implement comprises a retaining box defining an axial bore and a tubular drawing point affixed to an outer end of the retaining box for receiving India ink from the axial bore of the retaining box. A retainer for a floating weight is threadedly fastened to a threaded inner end of the retaining box. The retainer defines an axial bore in alignment with the axial bore of the retaining box and comprises an elongated tubular portion extending through the retainer box bore and a bottom closing an inner end of the retainer. A floating weight is guided for axial movement in the axial bore of the retainer and a portion of the retaining box bore. The length of the tubular retainer portion is sufficient to guide a major portion of the floating weight and the bottom of the retainer limits the stroke of the axial movement of the floating weight.
