FOUNTAIN PEN.
Application filed Gctober 2G, 1922.
To @ZZ 2li/lam t may conce/Mi.'
lie vit known that l, NICHOLAS B. PANOFF, citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful lmprovements in Fountain Pens, 'of which the following is a specilication.
My invention relates to fountain pens and has a particular reference to fountain pens employing ieXible ink containers.
The object of my invention is to provide a fountain pen in which the ink passage between the ink container and the pen is closed when the cap is placed over the pen, and is opened again when the cap is removed from the pen and placed on the rear end of the body of the fountain pen.
My invention is more fully described in the accompanying specification and drawing in which- Fig. 1 is a sectional elevation of my fountain pen in an operative position, and Fig.
2 is a sectional elevation of this pen in an inoperative position.
My fountain pen consists of a barrel 1 forming a body of the device. The rear end of the barrel is closed, and the front end is adapted to receive a. plug 2 supporting a pen point 3. The rear end 4 of the plug is made of a smaller diameter, and a rubber bag 5, forming an ink container, is placed tightly over this reduced portion or neck of the plug 2. A tubular passage 6 forms a duct from the inside lof the bag to the pen point 3.
A sleeve 7 is placed over the barrel 1 and is provided with threaded ends 8 and 9. The barrel 1 has two elongated apertures 10 and 11. A block 12 is placed in the aperture Y 10 with an inwardly extending lug 13. This lug is riveted throughV the block 12 to the sleeve 7. The block 12 is made shorter than the aperture, so that the sleeve 7 can slide on the barrel up and down being limited in this motion by the amount of clearance between the block 12 and the aperture 10.
Wlith the sleeve 7 in its lowest position the lug 13 rests against the plug 2 over the opening of the passage 6 with the portion of the bag 5 clamped between, thereby eifectively closing this passage.
rlhe surface of the plug end around the opening of the passage 6 is trimmed or Serial No. 597,118.
tapered so as to conformy with the shape of the lug 13.
A closing cap 14 is provided with threads adapted to engage threads 8 and 9 of the sleeve 7. Shoulder 15 bears against the lower edge of the plug 2, so that when this cap is screwed on the lower end of the sleeve 7 it forces the sleeve down until' the lug 13 closes the passage 6 and the block 12 reaches the lower edge of the aperture 10. In this position ink cannot iow from the container to the pen.
A similar block 16 is placed in the upper aperture 11 with the sanie clearance as the lower block 12. A fiat spring 17 is riveted to the sleeve 7 through the block 16. The spring is slightly curved inwards, and its upper end rests against the bottom of the barrel l.
When it is desired to use this pen, the cap 14 is removed from the lower end and placed on top of the pen. By screwing this cap over threads 9 until the shoulder 15 rests against the top end of the barrel, the sleeve 7 will be forced upwards until the blocks 12 and 16 strike the upper edges of the apertures 10 and 11. ln this position the ink passage 6 will be open, so that the ink can flow to the pen point 3. The spring 17 will be curved inwards (Fig. 1), exerting pressure of the bag 5 and forcing some of the ink into the passage 6 and to the pen point 3, making same immediately ready for operation.
n order to close the pen the cap 14 is screwed on the lower end thereby shifting down the sleeve 7. The spring 17 will recede again, and the suction of the expanding bag 5 will withdraw the ink from the passage 6 just before same is closed with the lug 13.
Important advantages of my fountain pen are that it can be effectively closed and can be carried or kept in any position without any danger of the ink being spilled.V Also it prevents the evaporation of the ink from the pen point and clogging of same by the drying ink. rlhe pen point is always clean and always ready for work.
I claim as my invention:
1. ln a fountain pen, the combination with a barrel, a plug in one end of said barrel, a pen point supported by said plug, a flexible ink container inside of said barrel and attached to said plug, a tubular passage in said plug 'from inside of said eontainei` to said pen point, a sleeve threaded on both ends and slidingly mounted on the Outside of said barrel, a closing` cap for said pen pointada-pted to engage said sleeve, means to close said tubular passage, and means to Withdraw the ink from said tubular passage when said pen is not in operation) said means being operated by said sleeve.
2. In a fountain pen, the combination with a barrel, a plug in one end of said bairel, a pen point supported by said plug, a flexible inl; eontainei inside oit' said barrel and attached to said plug, a tubular passage from inside of said contadine/1l to said pen point, a Closing Cap for said pen point, and means to close said tubular passage by press ing one side of said container against the innei' end of said plug with said tubular passage7 said means being operated by said Closing cap.
3. ln a fountain pen, the combination With a baiiel, a plug in one end o'tl said bai'- i'el, a pen point supported by said plug, a flexible ink container inside of said barrel and attached to said plug, a closing eap for said pen point, and a flat spying slidingly mounted inside o't' said bai'iel and adapted te be moved by said Closing cap and iuithei adapted to be deflected by said movement against said flexible container when said pen is in operation.
Signed at New York., in the County of' New York' and State ol' New York, this 9th day of October, A. D. 1922.
