Specification of LetfjersPatent.` Pgttjyged Apr, 12, 1921,
Application lcd October 16,1913. Serial No. 331,165.
T0 all whom t may concern.' Y
Be it known that l, HERMANN BURKHARDT, citizen of the Republic of Switzerland, residing at liueschlikon, of the Canton Zurich, of Switzerland, have invented new and useful Improvements in Fountain Drawing- Pens, of which the following is a specification.
This invention relates to a fountain drawing pen, the ink receptacle of which can be displaced in an axial direction and is guided in an outer tube. The open upper end of said receptacle is generally pressed by the pen against a plug and thereby closed quite air-tightly, the plug being firmly connected to the above mentioned tube. To the lower end of the ink receptacle, which projects beyond the outer tube, a button is fixed within easy reach ofthe fingers. Tf this button is pressed downward, the upper end of the ink receptacle deviates from the aforesaid closing plug, allowing the air to penetrate into the ink receptacle whereby ink is forced into the pen. 0n releasingvthe button, the ink receptacle returns to its closing position by the action of a spring.
0n the accompanying drawing, one form of the invention is shown, as an example, in-
Figures l and 2 by two ylongitudinal sections displaced by 900 one from the other;
Fig. 3 represents a device for regulating the opening of the pen in open position.
Fig. l shows a modified form of such a device in two different positions.
Referring now more particularly to Fig. l, the ink receptacle consists of a lower narrow tube a and of an upper wider tube connected to the former by a thread formed on the enlarged head c of the tube a.' The upper tube is guided in an outer tube (Z and can be displaced therein; its upper end is open and a socket e is inserted therein, the bore of which is conical at the upper end. An elastic plug j", of rubber forv instance, fits `into this bore and is fixed to the head g of tube d. The tubular lower part of this head is screwed onto the tube d and provided with a lateral opening 7L which brings about at the proper time the communication between the ink receptacle and the atmospheric air.
Between a collar formed by the enlarged head c of the lower tube a of the ink receptacle and the thickened part i of the guidetube (Z, a compression spring it is inserted which tends to press the ink receptacle-up- Y ward and against the closing plug.
To-the lower partz'of the tube d, a nut m isconnected by means of a screw socket Z,
said nut carrying the two' pen branches n.
Just below this nut a button o is provided f for on the receptacle tubelwand fixed by an adjusting screw. The button o vprojects radially a little beyond the nut m and the pen branches n and can thus easily be reached by the fingers guiding the pen, especially by the middle finger, without influencing, in any way the holding of the pen.
The normal positions of the ink receptacle, the outer tube Z and the part firmly connected to that tube is that shown in Fig. l. The interior of the ink receptacle is shut ofi' from the admission of air by the plug f. Should lack of ink be noticed, the ink receptacle is pressed downward by a pressure on the button against the actionl of the spring 7c. This can be done while drawing by the hand guiding the pen. Thereby the ink receptacle passes into the position illustrated in Fig. 2 in which the inserted socket e Vis removed from the plug f at the upper end of through opening la, (see arrow in Fig. 2).
VOwing to this admission of air ink can drop Vfrom the ink receptacle into the points of the pen. As soon as the required quantity of ink has been admitted, the button is released enabling springrc to force back the ink receptacle into the closing position as illustrated by Fig. l.
Along the lower end of the receptacle part a, a displacing device provided with al catch member p and a collar-shaped spreading `member Q, is guided. By displacing said device the pen branches n can be more or less spreadapart (see Figs. Sand 4,. position marked in dot and dash lines), thus permitting the branches to be readily cleaned and the thickness of line to be regu lated. v
Referring now more particularly to Figs. l and 3, the aforesaid displacing device slides on the smooth surface of part a, while according to Fig. 4; these parts are connected one to the other by a thread.
ln the drawing a wire fr' is shown inthe lower receptacle part a, which Wire assists in the removal of obstructions and also in controlling the feed.
Having described the nature o' my invention7 what I claim as new and desire to secure by Letters Patent of the United States l. A fountain drawing pen comprising an ink receptacle guided in an outer vtube provided at the top with an opening for the admission of air7 and which can be displaced therein in an axial direction and is normally pressed upwardly by a spring so that its upper open end is forced againstV a closing plug firmly connected to the outer guide-tube, thereby shutting off atmospheric air, said receptacle also carrying a button within easy reach'of the fingers guiding the pen, in such a way that the upper end of the ink receptacle is removed from the closing `-closing plugis formed of elastic material and is ixed to a head which is fitted onto the upper end of the guide-tube, said head being provided with an opening for the admission of air.
In testimony whereof I have signed myV name to this specification.
