Application filed January 30, 191'?. Serial No. 345,356.

To all whom 'it may concern:

Bc 1t known that'I, FRANK M. Asumir,

I acitizcn of the United States, and resident of New York city, borough lof Brooklyn,

in ythe county of Kings and vState of New York, have invented certain rre/ni and useful Improvements -in Fountain-Pens, of' Which the following is a specification.

My invention relates to fountain pens and the object of my invention -is to provide a construction of simple parts, easy to lill, large ink capacity, and ornamental in appearance. Further Iobjects and advantages are hereinafter described and .specifically referred to in the claim..

Figure l, is a longitudinal sectional View of a fountain pen embodying my invention.

F ig. Q, is an exterior vienr of the same showing the air .compressing cylinder in.

section and the preferred means of securing an easy sliding air tight it between the said cylinder and the barrel of the pen.

Fig. 3, is an enlarged view of one end of the pen shown partly in .section to disclose the lubricating' material located in the an nular grooves formed in the outer surface of the barrel.

-A, indicates the barrel of the pen provided with a reservoir A. B, indicates the feed plug; C, the pen proper, D, the cap;

stood, but I prefer to use the capi) for the reason thatit will present an ornamental appearance When made of silver Where the member H is also madeof the same material, thus presenting a metal casing which may bechased or ornamented in any desired manner. l r

I prefer to make the barrel A, of rubber .and to form a number of concentricgrooves indicated by A2 in its periphery, the edges being formed sharp as shown so that the compressing member H will cause these sharp edges indicated by A3 to bend or give slightly when the compressing cylinder is `forced over them, permitting the said cylinder to move freely .and `smoothly over the through. the feed barrel and yet maintain an air tight joint between the barrel and interior of the compression cylinder'. The cork disk G alsoacts to eifect an air tight joint between the said cylinder and barrel and also keep a tight join't'between the barrel and plug l?, and `therefore I may omit the grooves, if li desire, on account of the extra expense in man. ufacturing the barrel, but where a goed long life construction is desired, l prefer te use the grooves. l may also use a lubricant of graphite or soap in the grooves and this is illustrated in Fig. 3.

rhe plug l? is screwed into the end of the barrel and .is provided with a projection il" over which the open end of the expansion member E is fitted. A passage z serves to connect the chamber l and interior of the expanding member', which is preferably made of soft rubber and extends approximately the length of the barrel and is very small in diameter so thatalmost the Whole' capacity of the reservoir is retained tor-the storage of ink. The exterior diei 'er of, the compressing member is preferably made equal to that of the barrel at the point vll, and the open end of the cap is madetoeyer' lap the adjac it end of the member lil, thus entirely incasing the barrel A in a, thin metal casing.

The end ot' the member H is tapered at H to correspond with the taper formed on the end of the plug F and with 'the cap D at D and therefore the member H is nor` mally held by friction to the member E and the cap D .may "be held to the member H when, the tapered portions are brought together. Y

To fill the pen the cap l) is removed, the

compressing member moved outward on ,l

the barrel as illustrated in Fig. ,2, and their `by covering the hole K by a inger andeli'dthe cylinder H to its position shown in Fig. l, the air trapped in the chamber l: forced into the expanding member E cau's' ing it to expand and drive the air from ,the reservoir A. Then by placing the pen C. beneath removing the finger from the hole .-K, vthe air compressed in thememb'er A will esl cape, due to the contraction of the rubber member E, thus causing rareractionin thev ice the surface of theinlr supply and reservoir A and the ink Will then -floWk passage in the plug B and vinto the reservoir.
