To all whom it may concern:

Be it known that I, FRANCIS 0. BROWN, a

. citizen of the United States, and resident of New Bri hton, Staten Island, borough and county 0 Richmond, city, and State of New York, have invented certain new and useful Im rovements in Fountain-Pens, of which the following is a specification.

My invention relates to fountain ens and particularly to that t pe in whic a nibcarrying feed-bar is a apted to be projected from the barrel or retracted into the same.

The object of my present invention is to prevent the spatterlng of ink at the moment when the pen is in use or when withdrawin it therefrom, and to properly position and steady the nib in the writing osition.

Reference is to be had to t e accompanying drawing in which Figure 1 is a longitudinal section of a fountain pen showing the nib in position for use; ig. 2 is a cross section on line 2-2 of Fig. 1; Fig. 3 illustrates another form of pen with my present invention applied thereto; and Fig. 4 is a partial view of the same pen in the closed position.

In Figs. 1 and 2 the barrel A is rovided with a nozzle A havin a screw-t read A to receive the cap B an an internal incline or shoulder A", the purpose of which will be fully explained hereinafter. The feedbar C is suitably guided in a packing D located at the rear end of the barrel and the front end of this feed-bar carries the tongues C,.C between which the nib E is adapted to be received. In this form of the pen the nib is projected and retracted by the action of a pin B located within the cap B and ada ted to engage either the rear end .of the fee bar C when the cap is placed on the rear end of the barrel, or a recess or abutment C provided at the forward end of the feed bar.

The features described so far have been disclosed in prior-patents of mine. According to my fpresent invention I place at the rear end 0 the tongues 0', C that is adjacent to the abutment G a ring or collar F, the diameter of which is greater than the internal diameter of the nozzle A, but of internal diameter adapted to engage the shoulder A when the pen is in the writing position. The rlng might be placed loosely around the "fee tongues C, C but I prefer to hold it in earlier constructions.

'end of the ca place securely by fitting it into a curved slit at the forward end of the feed bar and the rear edge of the ring may be beveled to facilitate its insertion. In any event, however, the rin F surrounds both feed tongues and is coated eccentrically with reference to the axis of the feed bar, or rather to'the pen eccentric arran ement is as follows: As will be seen from ig. 1, the lower tongue C is bent sharply and has a tendency to throw the feed bar to one side as the nib carrying portion passes through the nozzle A. The

eccentric location of the ring F counteracts this tendency and insures a proper position of the pen when projected. It will be seen that the ring F engages the inclined shoulder A along its entire periphery and the ring therefore forms a perfect seal or valve closing communication between the ink reservoir and the outside except forthe slight seat. The reason for this feed channel which is left on'the upper face of the nib at each side C As the ring becomes seated and unseated uniformly on and from the entire circumferences of the inclined shoulder A" I avoid the spattering of ink which has been jectionable feature of some The diameter of the ring is practically the same as that of the forward portion of the feed bar.

found an 0 While in Figs. 1 and 2 the pen is advanced and retracted by the pushing action of the cap,.-1n Fig. 3 I have shownmy invention applied to a pen in which the advance and of the upper tongue withdrawal of the nib are effected by turn ing a spirally grooved sleeve G which is located at the rear end of the barrel and receives the feed bar C together with a pin (1* projected from the feed bar through the spiral slot of the sleeve into a longitudinal slot A of the barrel. In the particular construction shown the sleeve is. ada ted to be turned by means of a button secured thereto and provided with an axial recess Gr to receive a pin B projected from the closed B at the outside thereof.

The purposeo this pin or lug B is to temporarily connect the cap with the button so as to prevent loss of the cap, but it is not intended that the ca should beused as a means for turning the button G. The ring .F would be the same in this construction as in the one described above. This ring,- does since the inner surface-of the ring is spaced not exert any binding action on the-nib E i inclined internal shoulder at inner surface engages the tongue C in the construction shown.

It is not necessary,

however, gagement and the ring might surround the ton ues C, C loosely. The avoidance of a bin ing action on the nib is an advantage of considerable importance in as much as it allows the nib to be removed readily when desired, with the pen in the writing position.

-I claim as my invention:v

1. In a fountain pen,the the barrel having a reduced combination of nozzle and an the inner end of the nozzle, a nib-carrying feed bar movable lengthwise in the barrel and provided at its forward end with tongues adapted to receive the nib between them, and with a .collar arranged to engage the said inclined shoulder along its entire circumference, and gneans for advancing and retracting the feed 2. In a fountain pen, the combination of the barrel having-a reduced nozzle and an inclined internal shoulder at the inner end of the nozzle, a nib-carrying feed bar movable lengthwise in the barrel and provided at its forward end with tongues adapted to receive the nib between them and a collar surrounding said tongues and adapted to engage said inclined shoulder along its' entire circumference, and means for advancing and retracting the feed bar.

3. In a fountain pen, the combination of the barrel having a reduced nozzle and an inclined internal shoulder at the inner end of the nozzle, a nib-carrying feed bar movable lengthwise in the barrel and provided at its forward end with a tongue adapted to engage the nib from above an with a collar arranged to engage said, inclined shoulder along its entire circumference and surrounding said tongue, and means for advancing and retracting the feed bar.

4. In a fountain pen, the combination of the barrel having a reduced nozzle and an inclined internal shoulder at the inner end of the nozzle a nib-carrying feed-bar movable lengthwise in the barrel and rovided at its forward end with a tongue adapted to engage the upper surface of the rub, and

- with a collar arranged eccentrically to the pen seat and surrounding said tongue, said collar being adapted to engage the said inclined shoulder along its entire circumference, and means for advancing and retracting the feed bar.

5. In a fountain pen, a barrel, a nib-carrying feed-bar mova le therein lengthwise, a rotary button located at the rear end of the barrel and provided with an axial recess, the said button being exposed so that it may be operated by hand, a cap provided with an internal pin and that there should be such an enbarrel having a clined internal shoulder at the inner end of an external stud, the saidpin actin as a stop to prevent contact with the nib w en the cap is laced on the front end of the barrel and t e said stud fitt' in the axial recess of the button when place on the rear end of the barrel?- 6. In a fountaiingen the combmation'of a re need nozzle and an inthe nozzle, a nib-carrying feed bar movable len hwise in the barrel and provided near its orward end with an enlarged body and a tongue extending forward of said body the ton e being a apted to engage the back sur ace of the nib, a collar surrounding the tongue and arranged eccentrically to the said body, the said collar being adapted to engage the inclined shoulder at opposite points, and means for advancing and retracting the feed bar. 7
