T0 all whom it may concern .i

Be it known that I,

Hoboken, in the .county of Hudson and State of New Jersey, have invented certa-1n new and useful Improvements in Fountaln- Pens, of which the following is a 'speclication.

struct a fountain three tubes of suitable material in which the inner tube acts as a protection to the elastic sack, into which is sucked by compressing said sack by air pressure, produced by drawing the inner sliding tube out, letting air into the tube through an opening in the top of the said tube and then placing the finger over the opening to retain the air and pressing the same back to its normal position an thus compressing the sack alongA its whole length thus forcing the air or ink that may be contained .in the sack out. The pen nozzle is then inserted into the ink, the opening at the other end released, and the vacuum sack is iilled Awith ink. The interior tube is provided at its outer upper end, wlth a shoulder, which engages with the shoulder provided on the lower inner end of the middle or compression tube, and is thus prevented from being pulled entlrely off the innermost tube. Furthermore, the shoulders on the two inner tubes act as a packing to prevent the air pressure being partly' lost, s1nce they form a practically air tlght compartment, so long as the end opening is covered.

Another object I have in view, is so compressin .the sack, that it will not collapse, and wi carry suicient ink to fill the entire length of the be. l

plungers and other de vices have been tried but in suchcases the size and cannot carry sufficient ink, the sack in many cases buckling, thus preventing the inlet of ink in suicient quantity.

I attain these objects by' means of the mechanism shown on, the accompanying drawings, in whichl Figure 1, is a vertical sectional view ofA a fountain pen embodying the chief particulars of my invention. Fig. 2, is a vertical sectional view, with the central tube drawn Specification of Letters Patent. nppncationmed March 2s, 1914. serial N0. 827,806.

Flg. 4, isa vertical sectional' view show-` 4 is a shoulder which ts tightly into the Y,

forward end of an inner tube 7, the forward end of the said inner tube being forced into the recess 3 between said shoulder 4 and the threaded end of the nozzle in order to make a tight j0int;'5 is a shoulder narrower at its base, in order to form a collar to which thesack 6 is tightlypfixed by any -suitable means.

7 is the inner tube having at its rear end the shoulder 7*". A y 8 is the outer casing or tube, which may be constructed of hard rubber or any suitable material andis provided at one end on side with a thread 13 to` lock the same with the noz'zlethread 2.

9 is a cap showing a centralair is drawn for the purpose of compressing the sack to charge the same with ink. -This cap maybe attached to the tube 7 by friction and may be of sulcient length to serve as a cap for the nozzle and pen although` the cap 9 being conically shaped, may serve as a holder for a protecting cap for the nozzle, but not here shown. 'g

10 are the air openings;

11 is a space formed between the inner and outer tubes, in -which the packing 7a slides. Of course these will be tted to allow the tube 7 to be forced down, without too much resistance; 12 is the sack 6,

the nozzle 1. l

To fill the pen it is only necessary to draw out the tube '7, by means of the cap 10.

Then the vfinger is Pressed' over the opening and the tubes 7 is pacln'ngs 7 and 7 a shown 1n a compressed form,v 'brought about by the pressure of the air orced back to its normal 11,0

g3 ineens@ osition, to compress the air, which in turn sack attached to said nozzle by said 1s forced along the sides of the sack, which shoulder, a recess on said nozzle, an inner is thereby compressed along its entire length barrel surrounding the sack and the inner and the contents forced out. rlhe nger is end of which is depressed in to said recess 5 then removed, and the collapsed sack draws the outer end being open, an outer barrel 2o up the ink, and becomes filled throughout. carried by said nozzle, a tube slidable be- Practice has shown that vby the use-of my tween said barrels and having a cap at its construction the fountain pen will hold rear end withan opening therein. quite a large quantity of ink while the tube Si ed at New York city, in the county 10 is protected from collapsing or buckling by of ew York and State of New York, this 25 the protection aorded by the inner tube. 26th day of March, A. D. 1914.

What l claim as my invention and desire HIS ABEGG. l to secure by Letters Patent, is Witnesses:

A fountain pen Acomprising a nozzle, a LEOPOLD JE. PICARD,

15 shoulder on said nozzle, and e compressible HENRY H. FREDER.
