Fatented (Pct. 5, 1915.
Application filed July 10. 1913. Serial No. 778,335.
T0 all whom t may concern:
Be it known that I, ROBERT L. WARNook, citizen of the United States, residing at Warnock, in the county of Belmont and State of Ohio, have invented certain lnew and useful Improvements in Fountain-Pens, of which the following is a specification.
This invention relates to fountain pens and has as its primary aim to provide an improved cap for such a pen so constructed as to prevent the leakage of the ink from the pen when carried in the pocket, and regardless of the manner in which the pen is disposed within the pocket.
The invention contemplates the provision within the main or ordinary cap closure of an auxiliary cap having a socketed end to receive the pen section, which end ofthe auxiliary cap bears against a washer at the pen end of the barrel, and serves to seal the barrel and prevent the leakage of the ink as above stated. v In the accompanying drawings, Figure 1 is a longitudinal sectional view through the pen embodying'the present invention. Fig. 2 is a vertical transverse sectional view on the line 2-2 of Fig. 1.
In the drawings, the numeral 1 indicates the barrel ofthe pen and this barrel at its butt end is interiorly threaded to receive a plug closure 2 which may be removed when it is desired to fill or clean the barrel. At its other end the barrel is exteriorly tapered as at 3 and inwardly of its tapered portion is exteriorly threaded as at 4. This end of the barrel is interiorly threaded as indicated at 5, to receive the pen section which consists of an exteriorly threaded plug 6 having a bore 7 which serves the purpose of an ink duct to feed the ink to the pen. The plug 6 is provided at one end with a nib or extension 8 located substantially axially of the plug and having formed therein a continuation of the duct 7. The pen is indicated by the numeral 9 and is fitted upon the extension 8 and into the duct 7 in the mannerV clearly shown in Fig. 1 of the drawings. As stated above, an auxiliary cap is pro vided and this cap is indicated in the drawings by the numeral 11, and is formed or provided at one end with a threaded stud 12 which projects axially therefrom. The cap 11 is fitted into the main cap of the pen, which latter cap is indicated at 13 and is interiorly threaded at its open end as at 14 to engage with the threads 4 of the barrel 1. The threaded stud 12 ts through an opening 15 formed in the closed end of the cap 18, and threaded onto the stud is a millednut 16 which may be tightened for the purpose of drawing the end of the cap 11 securely and snugly against the closed end of the cap 13, whereby to connect these parts. It will be understood, of course, that by unscrewing the nut 16 the cap 11 may be re moved from the cap 13. The cap 11 is formed with a socket 17 in that end opposite the end from which the stud projects, and this socket is of relatively small diameter, itl being preferably only sufficiently large to receive the pen section 8 and pen 9.
A washer 10 is permanently secured in any suitable manner to the end of the auxiliary cap when the cap 18 is fitted on to the barrel, the washer will be brought to bear rmly against the end of the barrel and completely seal the pen and prevent the leakage of ink therefrom. It will be apparent from the foregoing that the pen embodying the present invention may be placed in any position in the pocket without likelihood of leakage of the ink and that when the main cap is removed the auxiliary cap will be at the same time removed.
It will be observed that the threads 4 are located substantially midway between the ends of the barrel so that when the cap 13 is removed from the pen holding end of the barrel, it may be fitted on to the butt end of the barrel while the pen is in use.
Having thus described the invention what is claimed as new is:
In a fountain pen, a barrel, a pen section l mounted at one end of the barrel, a cap re movably litted onto the said end of the barrel and provided at its closed end with an opening, an auxiliary cap fitted into the 11 and it will be understood that 'rst mentioned cap and having a threaded `Close the said pen section when the main cap ggV 1,155,693

stud projecting through the said opening', the said auxiliary cap being arranged to ns tted onto the barrel, anda nut threaded upon the stud and bearing against the closed end of the mam cap.
