FOUNTAIN-PEN.
Specification of Letters Patent.
Patented Sept. 3, i912.
Appication ledanuary 10, 1912. Serial :Na` 670,424.
To` all whom tm/ay concern:
Be it hnownthat I; FELIX RIESENBERG, av
citizen of the United' States, residing in the borough of: Manhattan, city, county, and
tion of such azpen, eliminate inkjoints andsecurel a larger ink capacity than is now possibley in this type of'pen.V Other incidental advantages will be'referred to in the following specication, or be apparent froman examination of the. structure.
In said'i drawings, Figures 1, 2 and`3 are longitudinal sectional 'views illustrating three substantially. equivalentforms of theA invention .Figsr 4,- 5 andare transverse sectional views ofthe several forms ofV pen illustrated' inFigs. 1, 2 and 3 on the lines 4 4-, 5 5 and=66l Figs. 7, Y8- and 9 are corresponding' sectional viewson the lines THT, 8"-8 and.9'-9. Fig. '10 is a section on the linel( )-10Fig. 3.
. Themainibody or font 1 ofthe pen is as shown, preferably integral with the finger or neclr portion .2, the use of the usual `joint bletween theseportions being avoided and ""I''thu's a-frequent causefof 'soiling the fingers eliminated. Within the mouth of the finger portion 2 is plac'eda feed section-3 having usual ink passage 3a andthe pen tis held between the feed' 3 and the wall of thefin-ger or neck portion 2. The feed' 3 has a 40 bore 5 within 'which is inserted loosely the endet the small tubeI 6, which has a'bore of greatly less dia-meter than thatv of the font 11 At its Aother end 'the tube 6, in the forms of the invention shown in Figs. 1, and-2- is passed through and rigidly'held 'by the bot-- tom 7v of a nipple 8 containing a valve' chamber .9. In the formof the invention shown in Fig. 3, the' tube 6 is 'formed in the wall of the font itselfand at the end toward 'thepeny has its opening coincident with the upper end of the bore of the feed member 3. Within the valve chamber 9 is arranged a checkV valve 10 which may, as shownfin Fig. 1, be anannular ring or as shown in Figs. 2 and 3, be a Vdisk valve with feather guides 11, enabling the valve to move verti- State of New York, have invented certainv cally with reference to its seat on the bottom :of the nipple, but to prevent its dislocation therefrom. Through the said bottom of the nipple, one or more ports 12er-e arranged, the upperends of which afford a seat for the valve 10. bored and adapted to receive a small rubber bulb 13, as shown.. When the pen is to be filled its lower end .is inserted in the ink bottle with the neck f2 projecting below the surface of the ink thereof and the bulb 13 compressed, valve 10seatsitself and the air is then expelled l.through small tube 6 emerging beneath or 'near the pen point outside of' the font. i/Vhen the bulb is released a partial vacuum tcauses the ink to flow into the pen through the regular feed section, by lway of the feed passage 3a, the relatively greater causing the ink to rise more freely in the fontthan in that tube. The bulb 13 being sniall, the ink only partially fills the font land the bulb, must be again compressed, iwhereupon the check valve 10 again closes tand the air is expelled throughthe tube 6. The bulb 13 beingagain allowed to expand @the ink rises farther in' the font and the process maybe continued until the font, bulb' and ultimately the sm'all tube 6. are filledv with ink, a state indicated when air en.y
`ip A cap 14 maybeprovided to screw or 1press onto the font over the bulb 13, and Ithe usual cap (not shown) may also bepro- `vided to -cover the pen point.
It will be noted that when filling the pen, the ink will not lrise readily iny the small ltube because of the excessive skin friction Qleastresistance along' the pen font through @member 3. As the bulb is small it must be `comp'ressed and released a number of times to fill the font. The principle here adopted makes it possible to lill-the pen bythe use of a smallbulb which would not otherwise be possible. When the font proper is filled the bulb itself can be Vfilled and will act as :an additional reservoir forA ink. It is not intended that the valve 10, .shall have a tight fit with its seat and therefore when the pen is used in writing the ink in the bulb Aand Naive chamber escapes down into the font bylealring past the valve, thus making skin friction inthe long' narrow tube 6' `ceases to -escape from the lower end of the fthe feed. 'channel or channels 'inthe feedl The nipple 8 is centrally i @there-in andit therefore takes the line of all the ink available for use. lin order to empty the pen it is held above the ink surface and the bulb compressed and released as in filling.
It will be noted that the pen has noobjectionable sections to interfere with or soil the fingers while writing,- the usual joint between the neck and bod of the font is eliminated, the4 ink capacity of the font is very nearly as large as in the plain style of fountain pen; there are no moving parts such as pistons, etc.; the one valve used is of large dimensions and simple construction not easily deranged, and not tight fitting and furthermore is so arranged that gravity assists the easy action of the valve when the pen is being filled. The valve may be made of hard or soft rubber or other suitable material. Also fthe rubber bulb is small and can be easily replaced when worn out, the operation is simple and self evident, it is impossible to soil the fingers with ink when filling the pen and the forcing of air and ink through the small tube has the advantage of cleaning the pen beyond the point where the ink enters the feed passage in' filling.
lt will be understood that the several coustructions herein shown and described vare by Way of illustration only and that many otherfforms of vmy invention may be made within the limits expressed in the following claims without departing from my invention.
What I claim is: l
1. A fountain pen having an ink receptacle provided with a valve chamber at its -upper end opening into said receptacle and an ink passage at its lower end, a valve in said valve chamber controlling the passage from the valve chamber to said receptacle, and an air passageway leading from said valve chamber above said valve and discharging through the lower end of said receptacle.
2. ln a fountain pen, the combination of an ink font terminating at its upper end in a valve chamber, and having a feed passage at its lower end, a check valve in said chamber, and an air tube terminating in said chamber at one end and at the lower end of the font at it-s other end, and of such relatively small cross-section that the skin friction therein will substantially prevent the rising of fluid therein.
3. A fountain pen, comprising two tubes, one of relatively much smaller cross sec acer/,eee
tional area than the other communicating with each other at both ends and having in the connection at the upper end a checlr valve. c
4. A fountain pen having an ink receptacle provided with a valve-chamber at its upper end opening into said receptacle and an ink passage at its lower end, a valve in' said valve chamber controlling the passage from the valve chamber to said receptacle, and an air passageway connecting said valve chamber above said valve with said ink passage independently of said receptacle.
5. lin a fountain pen, the combination of ran ink font having a separate air passage extending substantially from one end to the other thereof, land a connection from said font to said air passage at their upper ends, a valve closing the upper end, ofthe font and controlling the connection between the point and the air passage, and a collapsible bulb connected to the upper end of the font.
6. l'n a fountain pen, the combination of an ink font having a separate air passage extending from near the lower end of the font to a point'near its upper end, a nipple having a valve chamber with which said air passage and font both communicate, avalve in the .said lchamber controlling the connection between the point and the air passage and a collapsible bulb connecting with said nipple.
7. ln a fountain pen, the combina-tion of an ink font having a feed member and a sepJ arate air passage extendin from said feed Sti member near the lower eii of the font to a point near its upper end, a nipple having a valve chamber with which said air passage and font both communicate, a downwardly closing check valve in said chamber controlling the connection between the point and the air passage, and a collapsible bulb on said nipple adapted to seat said valve and expel the air when compressed.
8. A fountain pen comprising an inl font, pumping `means connected with the upper end-of said font, an air tube leading from the upper end of said font and discharging through the lower end of said font, and a valve cont-rolling communication between the upper end of said tube and said ink font.
