While fountain pens are highly regarded because-of their convenience and portability, they are all subject to several objections,

one of which is the small quantity of ink which can be carried'by them, requiring frequent illing and very often at inopportuna times; moreover the act of lling is commonly accompanied by loss of ink and soiling of the lingers. A)

It also occurs, at times, that the use of another color of ink is desirable than that ordinarily supplied, or that a' liner or coarser pen point be preferred, which is' net possible with ordinary commercial fountain ens.

p It is therefore an object of the present invention to provide a pen capable of containing a lar er volume of Writing ink than 1s usual an which is so arranged as to entirely dispense with the ordinary 'filling means, the ink being held in a removable receptacle for which others ofthe same klnd ma be readily lea age of the ink.

A further feature is in the provision of means whereby a single writing implement maybe used with differently colored inks, or that the same ink may be supplied by pen points of different degrees of pliability and width of line produced.

Another purpose is to produce a fountain pen in which the body and cap are alike in diameter, thus avoiding the bulky appearance of the ordinary pens.

Another purpose is `the provision of a connecting sleeve or adaptor which may be attachedto any fountain pen for the purpose of producing-a duplex writing implement. I f

These severall important objects are .attained by the novel construction and combination of parts as hereinafter described and shown in the annexed drawings, formsubstituted without loss or- 19:9. serial No. 311,938.

ing a material part of this disclosure, and in which:

Fig. 1 is a longitudinal sectional view of a pen made in conformityv with'the invention.. v

Fig. 2 is a similar view showin a modilied construction wherein two in ependent pens are combined.

Fig. 3 is a side elevational view of the removable ink reservoir as used therein.

Fig. 4 is a fragmentary view of a modiied construction wherein the capsule is entirely encased within the barrel.

The pen body consists of a tubular barrel 10 having a rounded front portion 11 blending into a screw threaded element 12 from which extends a reduced collar 13 and reaching outward therebeyond a common pen point or nib 14. i

The opposite end of the barrel 10 is square across and contains a short internal screw thread 15.

Neatly `fitting the bore of the barrel 10 isla rigid tube 16 provided .at one end with a thread 17 engaged by a cap 18 which when the tube or capsule is to be entered in the barrel, is removed.

At the opposite end of the tube is another thread 19 ending at the shoulder of the knurled head 20. The thread 19 engages in the internal thread 15 of the barrel and forms a leak tight joint.

A cap 31 is bored to receive the pen point and adjacent elements, the cap being provided with internal screw threads to engage the barrel threads 12 or the reservoir threads 21 in accordance with the end of the implement to which it may be applied, the cap being furnished with nary type.

In the modified form shown in' Fig. 2, the outer threaded element 21 is bored to provide a recess 23 to receive -the nib of the pen 14 carried in a structure the exact counterpart of that previously described and .to which have been appended prime numbers for the purpose o illustration, the difference being that the barrels 10-10 and 16-16 are shorter in'length.

A connecting sleeve 24 tubular to receive a clip 22 of ordithe pen point and adjacent elements is rovided wlth internal screw threads on oth ends; one end adapted to engage the barre-l 12T and the other end to engage the barrel thread 21.

This arrangement permits of the use of two diierently colored inks or of two pens unlike in their degree of ineness, andproduces a duplex writing implement. This connecting sleeve might also be connected to threads on the back of any standard fountain pens for the purpcseof producing a duplex, and is in nowise restricted to be used in connection wvith the capsule 16. This connecting sleeve when so used cooperates with the end of one pen to ferm a cap fora second pen.

In the modified form shownv in Fig. 4, the rear end of the barrel 10contains a short external screw thread 26 to receive the threads of a cap or closure 25, this cap also being provided with similar external screw threads 2101 to be engaged by the cap 31 or the connector sleeve 24, as desired.

In this modification, the capsule or car-` tridge 16a'is entirely smooth and closed at one end to fit within the barrel 10 of the pen, the opposite end being provided with screw threads 17 to receive the cap 18,'as previously described.

In operation, when the ink needs renewing, the empty receptacle is withdrawn by unscrewing it from the barrel, or in the case where receptacle 16a: is used, the cap 25 is unscrewed, the cap 18 removed 'from a receptacle to be substituted and then inserted )in the barrel, at that time in anV inverted position with the pen in a substantially upright position. e Due tothe fact that the cap 31 is equivalent in size with thevpen barrel, less space is occupied anda neater appearance obtained.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and detailsthereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: Y i

1. The combination with two independent fountainpens provided with screw threads movabl engaged with the front or rear vends o either fountain pen whereby both pens may be rigidly joined together with pens opposed to produce a dup ex writing lmplement, said sleeve adapted at -other times to act -as a cap for one of the ens.

3. As Van article of `manufacture or use with two independent fountain pens which are to be joined and used as a duplex writing implement, a connecting sleeve adapted to be selectively removably engaged with the rear ends of both fountain pens, or with front end of one and the rear end of the other, whereby in the iirst instance both pens are presented for use and in the second instance the said sleeve acts as a cap for one of the pens.
