Patented Jan."18,'1938 FOUNTAIN PEN Glenn E. Johndohl and cuaora M. Sublette,
- Denver; Colo.
Application September 8', 1936, Serial No. 99,715 8 Claims. (01.120-42) This invention relates to a fountain pen and to means for furnishing ink to a fountain pen.
- The principal object of the invention is to provide a simple, and highly eflicient ink cartridge 5 and a pen for receiving said cartridge so that the user may purchase his ink in a cartridge which can be slipped into the pen and which will be automatically opened by the pen so as to be ready' for use, thus making itunnecessary for the user toever contact theink in its liquid state.
'Other objects and advantages reside in the detail construction of the invention; which is designed. for simplicity, economy, and efiiciency. r These will become moreapparent from the following description.
In the following detailed description of the invention reference ishad to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. 1 is a perspective view of the improved pen. Fig. 2 is a side view or. the cartridge employed in the pen.
Fig. 3 is an end-view of the cartridge.
Fig. 4 is an end view of the sleeve. 4
Fig. 5 is a side view of the cartridge sleeve.
Fig-6 is a longitudinal section through the cartridge with the sleeve in placathereon.
30 Fig. ' 7 is a'longitudinal section through the pen,-
illustrating the operation of opening the cartridge.
The pen consists ofa tip portion ill for supporting the usual pen point- The tip portion and the ink feeding mechanism therein may have any 35 of the usual constructions. The upper extremity of the tip portion is threaded to receive a barrel l2 and the upper extremity of the barrel I2 is internally threaded to receive a cap I3. These 40 parts comprise the complete pen.
M, as shown in Figs. 5 and 6. The cartridge is of suflicient length to extend within the'cap l3 and is formed with a tapered neck portion I! for receiving a sleeve l8. The neck portion H is 5 of smaller diameter than the remainder of the cartridge and joins the latter to form a shoulder thereon.
The" sleeve [8 is I! supported therein upon a cross bar 20 or in any other suitable manner. The cartridges are furnished to the user with the sleeve IS in place on the neck II, as shown in Fig. 6, and with a cork 2| at the shoulder between the neck and the cartridge for holding the ink in place therein.
To install the cartridge in the pin, the user re- '-latter from its seat in the neck IJ.
The ink is furnished for the pen in a cartridge formed with a central air tube Y moves the cap l3 from the barrel l2 and-drops the cartridge in place in the latter. This allows the head of the sleeve I8 to engage a gasket 22 which seals it against. the tip portion Ill. The cap I3 is now put in position and threaded into the barrel 12. The. inward movement of the cap' forces the cartridge into the barrel and into the sleeve l8, wedging the latter into the neck l1.
As the sleeve. 18 moves onto the neck H, the air tube' l9 contacts the stopper 2| and pushes the This allows the ink to flow directly through the neck and into the tip portion In, and also allows air to flow backwardly through the air tube I5 into the cartridge Hi. If the stopper is formed of cork or other light material, it will immediately float to the upper extremity of the pen as shown in Fig. 1 so as not to interfere with the flow of ink from the cartridge. I
After the ink has been used, the cap I3 is removed and the cartridge with its sleeve I8 is discarded and replaced. It is desired to call attention to the fact that all operating parts, such as the small air tube [9, etc. are discarded and renewed with each filling of ink so that the pen is maintained in the highest state of'emciency at all times.
.It is desired to call attention to the fact that the flow of ink in this improved pen is always toward the pen point. The direction of flow is never reversed as it is.in filling the usual pen. Therefore no foreign substances can be drawn into the pen to clog the flow passages thereof. There are no working parts such as ink sacks, plungers, etc. to become worn and damaged. The ink never contacts the barrel of the pen so if desired this may be made transparent and will remain so indefinitely.
' While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of'the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent ls:- I

. 3. A cartridge for filling fountain pens comprising: a tubular ink retaining portion; a neck portion; a stopper closing said neck portion; and a pushing member mounted in said neck for pushing said stopper from position after said cartridge is in place in a pen, said pushing mem-. her being hollow so as to form-an air tube and being of less diameter than said neck to allow the ink to flow through said neck around said pushing member.
4. A fountain pen comprising: atip portion;
r'ied in said barrel; a stopper closing the forward extremity of said cartridge; and a I projecting memberabutting said tip portion to force said stopper from place as said cartridge is forced into said barrel.
5. A fountain pen comprising: a tip portion; a barrel portion; a cap portion; a cartridge carried in said barrel; a stopper closing the forward extremity of said cartridge; and a projecting member abutting said tip portion to force said stopper from place as said cartridge .is forced into said barrel, said projecting member being hollow to admit air to said-cartridge and being of less diameter than the passage in the forward extremity of said cartridgeto allow the ink to flow from said cartridge about said projecting member.
6. In a fountain pen having a barrel and a pen-holding tip, provided with a central ink passage, threaded to the open extremity ofsaid barrel; a. tubular inkcartridge slidable into said barrel; a reduced neck portion on said cartridge;
45 a stopper initially positioned in said neck porat both extremities; a hollow air tube projecting from said cap member. into said neck portion;
and means on said cap member for supporting said air tube axially within said cap, said air tube projecting from said cap sufficiently far to force said stopper from said neck portion and into said cartridge as said cap member moves into position on said reduced neck portion.
'7. In a fountain pen having a barrel and a penholding tip, provided with a central ink passage, threaded to the open extremity of said barrel; a tubular ink cartridge slidableinto said barrel; a reduced neck portion on said cartridge; astopper initially positioned in said neck portion; a cap member fitted over the extremity of said neck portion, said cap member being open at both extremities; a hollow air tube projecting from said cap member into said neck portion; and means on said cap member for supporting said air tube axially within said cap, said air tube projecting from said cap sufiiciently far to force said stopper member from said neck portion and into said cartridge as said cap member moves into position on said reduced neck portion, the length of the cartridge with relation to the length of said barrel being such that the pen-holding tip oi. said pen will force said cap onto said neck portion as said tip is brought to position on said barrel.
8. An ink cartridge for fountain pens of the cartridge filling type comprising: a relatively long tubular container closed at one extremity; a reduced neck portion on the other extremity of said container joining the latter to form a shoul: der thereon and being slightly tapered toward its open extremity; a tapered, tubular cap member forced onto the tapered extremity of said neck portion; a cross member in the head of said cap member; an air tube supported by said cross member and extending axially through said cap member and'projecting from the other extremity thereof into said neck portion; and a stopper in said neck portion adjacent .said shoulder, said air tube terminating adjacent said stopper so that when said cap member is forced'onto said neck portion up to said shoulder, said air tube will force said stopper from said neck portion and into said cartridge to allow the ink to flow from said cartridge about said air tube while the air enters through said tube.
