FOUNTAIN-PEN FILLER.

Application led -May 23, 1925. Serial No. 32,483.

This invention relates to fountain pens and filling mechanism therefor and has for an object to provide an improved construction wherein the usual sack is eliminated and means provided for drawing a quantlty of ink directly into the barrel.

Another object of the invention is to provide a fountain pen in which a collapsible cup is provided at'one end of the barrel of a fountain pen and associated with a plunger for permitting a ready collapsing thereof for `expelling air from the barrel of the fountain pen.

A still further object of the invention is to provide a fountain pen witha filling mechanism at the end opposite the pen, the arrangement being such that the filling mechanism may be operated once or several times to partially fill or entirely 'fill the barrel of a pen.

. In the accompanying drawing Figure 1 is a view partly in elevation and partly in longitudinal vertical section, the same disclosing an embodiment of the in.` vention.

Figure 2 is a view similar to the right hand half of the' showing of Figurel 1, the same beingon an enlarged scale and the filling mechanism moved to a collapsed position.

Figure 3 is a'transverse sectional view through Figure 1 on line 3-3, the same being on an enlarged scale.

Referring to the accompanying drawing by numerals, 1 indicates a cap which may be of any usual construction and which isV normally slipped over one end of the barrel 2 so as to cover the pen point 3 and associated parts when the device isV not in use. The barrel 2 is formed ,l with the usual chamber 4 but in the present invention it is not necessary to provide a bag in this chamber as the ink is drawn directl into' the chamber and is fed therefrom 1n the usual manner as the penis used. The pen point 3 and associated parts are of any usual or preferred structure and form no part of the present invention except in combina,- tion. l The barrel 2 at the end opposite the pen point 3 is provided with a reduced passageway or bore 5 merging into an enlarged 1nternally threaded chamber 6. An annular de ression 7 is also provided intowhich the en arged annular portion or enlargement 7 3 uppermost.

of the collapsible cup 8 is mounted. If desired, the annular enlargement 7 maybe cemented or otherwise rigidly secured to the barrel 2.. An externally threaded sleeve 9 is screwed into the chamber 6 until the lower end thereof presses the enlargement 7 tightly and firmly into the annular groove 7. The sleeve 9 is provided with an apertured end 10 through which vthe rod or plunger 11 extends, said rod or plunger being preferably integral with` the cup 8, which cup is preferably' made from a good gra-de of rubber and which is adapted to be collapsed as shown in Figure 2 when expelling either ink or air from the chamber 4. 1

After the ink or` air has been expelled as shown in Figure 2, the en d of barrel 2 carrying the pointv 3 is submergedin ink` in case it is desired to again ll the chamber 4 andfthen plunger 11 is released. This will permit the cup 8 to gradually distend until it assumes the position yshown in Figure 1 and as it distends it will produce a suction or rarefaction in chamber 4 and in this manner draw into this chamber a quantity of ink. As shown, the ldisplacement of cup 8 is less than the chamber 4 and if it should be desired to entirely fill chamber 4 after the first supply of ink has been drawn therein, the entire pen structure is moved to a vertical position with the point The plunger 11 isagain caused to function until it assumes the position shown in Figure 2 and this vaction will expel a given quantity of air so that an additional supply of ink may be drawn in as the cup'again distends. This action is repeated several times or until the chamber 4 is completely filled. In' order that the plunger 11 may not be actuated accidentally, a -protecting cap 12 is screwed onto the outer end ofthe sleeve 9. This cap also acts as a flocky nut for locking the sleeve against accidental movement. After the chamber 4 has been filled or` partially filled,` the entire device then acts in the usual man ner ofv a fountain pen.

What I' claim is: 1. Ina fountain pen; a barrel having a reduced passage at the end opposite that car- IIU vided at its closed end with a short rod projecting out through an aperature in the end of the chamber, whereby when the cup has been collapsed in the chamber by the.

rod and the rod released, the cup will distend to produce suction in the barrel.

2. In a fountain pen, a barrel having a reduced passage at the end opposite that carrying the pen point and at said end an internally threaded chamber, a collapsible and extensible rubberv cup having its open end secured around the said passage and prof vided at its closed end with a short rod projecting therefrom to normally lie Wholly outside of the cup, and an externally threaded sleeve screwing into the said chamber around the cup and having an apertured end through which the rod projects.

3. In a fountain pen, a barrel having a reduced passage adjacent its upper end ank annular groove around said passage, and an internally threaded chamber at said end, a collapsible and extensible rubber cup having at its open end an annular exterior enlargement fitting in the groove surrounding the passage and provided at its closed end through which the rod 4 reduced passage adjacent its upper end and v an internally threaded chamber at said end, a collapsible and extensible rubber cap having its open end secured around the passage and provided at'its closed end with a short rod vprojecting therefrom to normally lie Wholly outside of the cup, an externally threaded sleeve of a length greater than the depth of the chamber and screwin into the same Withy a portion projecting t erefrom, said sleeve enclosing the cu apertured end k throu h Wh1ch the rod -pr0 jects, and an internay threaded cap screwing on the projecting end of the sleeve, said cap serving to protect the said rod and to and having an prevent accidental movement of the sleeve.
