UNITED STATES CHARLES P. CRAWFORD, OF LOS ANGELES, CALIFORNIA.

FOUNTAIN PEN.

Application filed March 29, 1922.

To all whom it may concern Be it known that I, CHARLES P. CRAW- FORD, a citizen of the United States, and resident of Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in a Fountain Pen, of which the following is a specification.

This invention relates to a fountain pen and pertains more particularly to a pen of the self-filling type. The primary object of this invention is to provide a pen with a removable self-filling ink well. Another object of this invention is to provide a pen of the character described so arranged that the ink well may be removed and replaced without the requirement of any skill. A further object of this invention is to provide details of structure whereby an easily assembled and disassembled pen is obtained, one which may be expeditiously and quickly filled, is durable, simple, and compact in structure.

Theseobjects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

The figure is an axial section through the pen showing parts thereof in elevation.

Referring more particularly to the drawing, 1 indicates a barrel having a bore 2 extending the greater length of the barrel. A bore 3 of reduced diameter communicates with bore 2 and forms a shoulder or ledge therewith. Adjacent the pen end of the barrel, the bore is enlarged in diameter as indicated by 5 to form a space to receive the pen. The upper end of the barrel is internally threaded, and it may be threaded externally adjacent its ends to receive caps.

Slidably and snugly fitting within the bore 3 is a stem 6. This stem has a head 7 which rests against the shoulder 4 and ink duct and pocket end 8 against which the pen 9 reposes. The pen is frictionally gripped between the stem and the barrel by being forced into the space between the wall of the bore 5 and the stem. The ink duct 10 feeds ink to the pen. The duct 10 communicates with a bore 11 of enlarged diameter and internally threaded. The stem may be slipped into position and removed in the same manner. A well 12, of transparent material is reduced in diameter at its lower edge to form a nipple 14. This nipple is externally threaded to engage the thread in head 7.

Serial No. 547,712.

Adjacent the upper end, the ink well is externally threaded as indicated by 15 so that it may engage with the thread on the barrel 1. It will be noted that there are a less number of threads on the nipple 14 than on the head 7. This is to prevent jamming of the threads. A head 16 is formed on the upper end of the barrel to receive a collapsible sack 17. This is preferably of rubber.

To fill the ink well, the latter is grasped by means of the sack 17 over the bead 16 and unscrewed from the barrel and the stem, thereby permitting it to be removed from the barrel. The nipple 14 may then be inserted in an ink reservoir, the sack 17 collapsed and permitted to expand so as to draw ink into the Well. After the well has been filled it may be inserted in the barrel and then screwed into position. If it is desired to clean the pen, the ink well is removed from the barrel, pen 9 is removed, and the stem 6 pushed inwardly into the barrel. This releases the stem from the barrel and it may be removed therefrom.

A cap 18 is provided to house the sack 17 and is screwed into position upon the end of the barrel. A similar cap 19 covers the pen end, when the latter is not in use.

It is obvious that I have provided a pen having an easily removable ink well so that it may be readily filled. The pen comprises a minimum number of parts, which may be easily disassembled for the purpose of cleaning. When assembled the pen is solid, and the parts are not easily disturbed.

What I claim is:

1. A self-filling fountain pen comprising in combination a barrel, a pen stem having an ink ductremovably fitted in said barrel, an ink well removably disposed in said barrel and abutting said stem, said well having an opening registering with said ink duct, and a collapsible filling sack on said well.

2. A self-filling fountain pen comprising in combination a barrel having an internal ledge, a pen stem slidably fitting in said barrel and abutting against said ledge, said stem having an ink duct, an ink well remova-bly disposed in said barrel and abutting said stem, said well having an opening registering with said ink duct, and a collapsible filling sack on said well.

3. A self-filling fountain pen comprising in combination a barrel having an internal ledge, a pen stem slidably fitting in said barrel and resting against said ledge, said stem duct and a bore at its upper end, said bore being threaded, an ink well having a thread for engagement with the thread in said barrel and having a nipple threaded to engage Said bore, and a collapsible filling sack mounted on said Well.

In Witness that I claim the foregoing I have hereunto subscribed my name this 23rd day of March, 1922.

CHARLES P. CRAWFORD.
