FOUNTAIN-PEN.
Speccation of Letters Patent.
Patented Feb. 18, 1908.
Application iiled March 6, 1907. Serial No. 360.910-y T o all wltom tt may concern:
Be it known that I, SIGMUND H. ENenLf' BERG, a citizen ofthe United States, residing at Brooklyn, in the county of Kings and Statevof New York, have invented new and .useful Improvements in Fountain-Pens, of .which the following 1s a speciiicatlon.
This invention relates to a fountain pen having the lower'end portion of the bore'or reservoir of the barrel of gradually diminishlng diameter and prorided with a feed bar with correspondlng tape]` or gradually dimini'shing diameter s'o as to give a tight fit.
The invention resides in certain features of construction set forth 1n the following speolfication and claim and illustrated 1n the annexed drawing in which Figure 1 is a sectional view of a pen embodying this invention. Fig. 2 is a side view of Fig. 1. Fig.'3 is a view like Fig. 1 the plunger being pushed in or to starting position. Fig.A 4 is a .section along :n 9C Fig. 1. Fig. 5 is a section along y y Fig. 3. Fig. 6 shows av modification.
The reservoir or barrel e is combined with aplunger or piston b. A bayonet joint the pin connections of which are shown at o unites the parts. The barrel can be drawn out or moved longitudinally. when'the pins run in the longitudinal branches of the grooves d of the bayonet joint. When the pms are 1n the transverse slot branches the plunger is locked in extended position to prevent the vplunger being forced. in or the contained ink being spurted out.
A; disk or Washer e of soft rubber` ooi-k or other suitable material in the plunger can sit to the end of the barrel and make a tight closure when the piston is pushed in or to starting position (Fig. 3'). The plunger or piston can be either outside the barrel or 'can be held `or seated on the plunger when fitted linside thereof as shown in Fig. 1 or 6 respectively. The outer end of the plunger corresponds in/ outside circumference to the barrel so'that a cap f for closing the pen end writing.
The bore of the barrel at its lower or pen end is of gradually diminishing diameter and the feedbar g is of corresponding taper or gradually diminishing diameter so as to give a tight. iit. This taper serves to prevent the feed bar g becoming loose or coming out at the pen end of the barrel. If it is desired to insert a new pen point the feed bar mustbe extracted through the top end of the pen. Often an owner of a pen tries to insert a new pen and sometimes ruins the instrument. With a pen of this character the pen must be brought to a repairer or to the manufacturer as tools are required for removing the piston 7J and extracting or inserting a new pen at the wide endv or mouth of the barrel. This taper also aiiords tight closure thus preventing ink from escaping between the feed bar g and inner side of barrel o.
What I claim is A fountain pen having a barrel with the bore of gradually diminishing diameter or tapered at its lower or pen end portion, and afeed bai` lying partially within said tapered portion and adapted to it the tapered por tion throughout that portion of its length which lies within the barrel so as to provide tight closure or iit.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
