4 Claims.

This invention relates to fountain pens, and more particularly to self-filling pens of that type, and aims to provide a novel and improved pen having, among others, the advantages hereinafter described.

In the embodiment of my invention described and illustrated herein: v

Fig. 1 is an elevation, with the pen protecting cover in position, partly broken away, for convenience; Fig. 2, a similar view of the cover with the cap removed;

Fig. 3, a vertical section of the barrel with the cover in barrel filling relation to the former; and

Fig. 4, a cross section, on an enlarged scale, through the barrel on line 44 of Fig. 3, looking down.

Referring first to Figs. 1,2, my novel pen is illustrated as comprising a usual barrel I, having 20 a nozzle 2 and pen 3, which are protected by a cover 4, with a thread 5, for engagement at its inner end with the barrel.

The top of the barreLFigs. 1, 4, is provided with an inturned flange 6, slotted at 1, Fig. 4, and within 25 the flange is received the reduced end portion 8 of a piston 9, this end portion having diametrically positioned thereon short ribs III, which are received by the slots I in the flange.

The piston reduced end is threaded as at I I, to

30 engage similar threads I2 on a nut I3, which closes the barrel end and locks the piston in inoperative position. The piston inner end is also interiorly threaded at I4 for a purpose to be explained.

The piston may be provided with a suitable washer I5, if desired. For operating the piston to fill the barrel I, I have provided novel means.

Within the cover 4 and near its upper end, Figs. 1, 2, 3, is pivotally mounted thereto, as by a stud 40 IS, an arm I1, bent at a sharp angle to form the downwardly extended arm I8, having pivoted to its forked end, as by a pin I9, the end 20 of a rod 2|, the opposite end of which is threaded to engage the thread I4 on the piston end 8, and, with 45 the arm I8, forms a piston rod for the piston 9.

The shoulder 22 on the end of the rod 2| limits the relative movement of said am 2| with respect to the arm l8.

, The lower edge of the cap I55, when on the barrel, rests upon the arm I1, and thus keeps the arm I8, and rod 2|, in position, parallel with the barrel I. 3

The arm II and rod 2| also constitute a very convenient form of clip for securing the pin barrel in the pocket oftheowner, ifhe wishes toso use it. By allowing the rod 2| to engage the outside of the pocket when the pen is placed therein, the natural spring of the rod will cause it to lock the pen in the pocket.

To fill the barrel, one first removes cap I55 from the cover, then removes the cover from the barrel, swings the arm I8 upwardly to position, shown in Fig.3, and then swings rod 2| in line with arm I8. Next, he holds the barrel with the pen downward, Fig. 3, screws the threaded end of the rod 2| into the piston, and turns it slightly, if desirable, to cause the lugs ID to engage the slots I in the flange. The piston caimot turn while the lugs and slots are engaged, and next he turns the rod 2| up tightly in the piston, unscrews the nut I3 to unlock the piston, immerses the pen end of the barrel in the ink, and pushes the piston into the barrel until it touches the end of the nozzle. On withdrawing the piston, a vacuum will be created, and ink will be drawn into the barrel, filling the same. If it seems desirable to repeat the operation, one turns the pen end upward, pushes the piston in gently until any air is exhausted and ink begins to issue forth from the barrel. He then reimmerses the pen and nozzle in the ink, and withdraws the piston to draw more ink into the barrel. Next, one turns the piston until its lugs III again engage the slots 1, unscrews the rod 2| from the piston, withdraws it from the barrel end, folds the rods I8, 2|, against the barrel as in Fig. 1, and replaces the cap I55.

The foregoing provides a very convenient and serviceable pen.

The nut I3, when turned up on the piston end, efiectively closes the end of the barrel, and the piston 9 is a much more efllcient means for filling the barrel than other means frequently used.

The piston rod, adapted to be used as a pen clip, is also a convenient and novel construction.

My invention is not limited to the particular embodiment thereof herein disclosed and described. 1

I claim: 1. A fountain pen comprising a barrel, a nozzle therefor to receive a pen, the top of the barrel drilled providing a flange, a piston in the barrel with a threaded inner end extended through the barrel top, means exterior to the barrel and cooperating with the piston for closing the barrel top and holding the piston in position while not in use, and a cover for the pen end of the barrel with means to reciprocate the piston when the nut is removed. 1

2. A fountain pen comprising a barrel, a nozzle therefor to receive the pen, the top of the barrel bored to provide a flange, a piston in the barrel with a threaded inner end extended through the barrel top and means exterior to the barrel and cooperating with the piston for closing the barrel top and holding the piston in position while not in use; a cover for the pen on the barrel, a jointed piston rod pivoted in said cover and adjustable to a right angle thereto for use and adapted to engage the piston to unscrew and operate it to fill the barrel.

3. A fountain pen comprising a barrel, a nozzle thereon to receive the pen, the top of the barrel drilled to provide a flange with a notch therein, a piston in the barrel with a threaded inner end extended through the barrel top and a nut thereon, the piston having a lug to engage the notch in the top flange, a cover for the nozzle, a jointed piston rod mounted therein and adapted to engage the piston to fill the barrel, and a cap for the cover acting to hold the piston rod in folded position while adapted to engage the clothing of the user to hold it therein.

4. A fountain pen'comprising a barrel with a cap therefor, a nozzle on one barrel end to receive a pen, the opposite barrel end having locking means to engage a piston and close the barrel end and lock the piston against movement when not in use; also locking means to lock the piston against rotation in the barrel while locking the piston rod to the piston, a piston lockable by both said locking means, and a. piston rod extended through a slot in the cap and pivoted to the cap and operable thereby at either a right angle or in vertical relation thereto and through one of said locking means.
