Description

No. 805,624. PATENTED NOV. 28, 1905.
J. BLAIR. FOUNTAIN PEN.
APPLICATION FILED MAY13,1905.
(L mentor Q/Vil'neooeo UNITED STATES JOHN BLAIR, OF BROOKLYN, NEW YORK.
FOUNTAIN-PEN.
Specification of Letters Patent.
. Patented Nov. 28, 1905.
Application filed May 13, 1905. Serial No. 260,231.
To all whom it may concern.-
Be it known that I, JOHN BLAIR, a citizen of the United States, residing at Brooklyn, in the county .of Kings and State of New York, have invented new and useful Improvements in Fountain-Pens, of which the following is a specification.
My invention relates to fountain-pens in which a nozzle or pen-section is screwed into the body or reservoir of the pen; and its principal object is to prevent leakage of the ink into the pen-cap and into the pocket through the holes in the cap should the pen be carried with the point downward or in a horizontal position.
Another advantage of this invention is found in the forward or backward adjustment of the nib in the reservoir to suit the preferences of different writers. The pen-section, with the nib, may be screwed entirely into the reservoir to allow the interior bottom of the cap to be screwed tightly against the front end of the pen-body to form an ink-tight joint, and so prevent leaking in whatever position the pen is carried or placed.
The accompanying drawings illustrate the invention, its various features being referred to by letters.
In the drawings, Figure 1 is a side view of the device with the cap on the rear end of the body and the nib adjusted deeply in the reservoir. Fig. 2 is a similar view with the nib adjusted well forward and the rear end of the body partly in section. Fig. 3 is an enlarged longitudinal section of the front end of the pen and the cap. Fig. 4: is an enlarged crosssection on lineman of Fig. 2, and Fig. 5 is an enlarged plan of the rear end of the pen-section.
The letter A designates the pen reservoir or body, having interior threads a and exterior threads a at its front end.
B is the pen-section, having exterior threads 6 to engage the interior threads a on the body. The rear portion of this section is of reduced diameter and is not threaded. The feeder (Z in the pen-section has a longitudinal recess rZ to receive the end of a stem f on the cap F. This recess is made of any desired form, and the stem is made to fit in it, so as to form a socket-wrench, whereby the pen-section is screwed down into the reservoir or entirely out from it in order to fill the reservoir with ink.
When the cap is screwed down upon the penbody, the edge of the latters open end con tacts tightly with the interior bottom of the cap and forms an ink-tight joint therewith.
In writing, the proper course of the ink is from the reservoir through the groove 0 in the feeder to the point of the nib (2; but, as already explained, the ink frequently works through the ordinary joint and out upon the exterior of-the pen, soiling the fingers and clothing. The double joint in this device effectually prevents this annoyance.
What I claim is- 1. In a fountain-pen a pen-section adapted to be screwed into the pen-body and provided with a longitudinal recess, and a cap having a longitudinal central stem extending outward from its bottom to engage said recess in said pen-section to screw the latter into and out of said body as described.
2. In a fountain-pen a body having interior and exterior threads at its front end, a cap having interior threads to engage the exterior threads on said body, a pen-section having exterior threads to engage the interior threads on said body and provided with a longitudinal recess therein, and a central stem in said cap to engage said recess in said pen-section to screw the latter into and out of said body, as described.
3. Afountain-pen having interior and exterior threads at its front end, a cap having interior threads to engage the exterior threads on said body, a stem projecting from the hollow of said cap, a pen-section having exterior threads to engage the interior threads in said body, and a feeder in said pen-section having a longitudinal recess between its front, central portion and said pen-section, to engage said stem in said cap as described.
4:. A fountain-pen having a pen-cap into which is fastened a stem having a form straight on one or both sides and a pen-section having a longitudinal recess of like cross-sectional form for engagement with said stem, as herein set forth.
In testimony whereof I aflix my signature in presence of two subscribing witnesses.
JOHN BLAIR.
