FOUNTAIN-PEN RESERVOIR.
Application filed May 5,
Z '0 all whom it may concern: 4
Be it known that T, JAMES E. LAFFIN, a citizen of the United States, residing in the city of Oquossoc, State of Maine, have invented new and useful Improvements in Fountain-Pen Reservoirs, of which the following is a specification, reference being had to the accompanying drawings.
This invention is afountain pen reservoir,
reservoir, adapted for insertion within the barrel of an ordinary fountain pen, and having means for releasing the ink for writing after the reservoir is so inserted.
In the drawing: v 4
Figure 1 is a perspective view of the reservoir, a section being broken out at the end to shown the arrangement of the valve.
Figure 2 is a longitudinal sectional view of a fountain pen with this improved reservoir mounted therein.
The invention consists of a tubular reservoir 1 adapted to freely slide into the barrel 2 of the fountain pen 3. One end of this reservoir is provided with a check valve 4 which is held to its seat 5 by means of an expansive coil spring 6 set over the stem 7 of the valve 4: and braced against a stop 8 at the end of the valve stem. The other end of the tubular reservoir is exteriorly threaded at 9, and an adjusting sleeve 10, interiorly threaded at -11 is screwed down over the threaded end 9. The device is then filled with ink through the valve 4, and is inserted in the barrel 2 in such manner that the stop 8 of the valve 4 rests against theinner end of the pen stock 12. When the pen is then held in position for Writing, the weight of and the object is to provide a tubular ink 1922. Serial No. 558,679.
the tubular reservoirll combined with the vibratory movement of the hand in writing, 40 will open the" valve 4 sufficiently to feed ink down therethrough; if not, then by unscrewing the sleeve 10 until it is impinged by the endof the barrel 2 as the latter is screwed down upon the pen sleeve 13, the valve will be forced open so as to allow ink to flow more freely.
While I have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claims.
I claim:
1. An ink reservoir for fountain pens, comprising a tube adapted to slide within the fountain pen barrel; a spring-set check valve, having a stem, mounted in one end of the tube with the end of the valve stem adapted to rest against the inner end of the pen stock; and an adjusting sleeve threadedly engaging the opposite end of the tube.
2. An ink reservoir for fountain pens, comprising a tube adapted to slide within the pen barrel; a check valve in one end or of the tube adapted to be opened by impinge ment against the inner end of the pen stock; and an adjusting sleeve on the opposite end of the tube as means for lengthening the device to accentuate the impingement of the re valve against the pen stock as the barrel is screwed down upon the pen stock.
