Definitions

  • the present invention relates to a fountain pen, which is provided instead of the usual writing pen with a rotatably mounted small ball, which constitutes the writing means. It is well known to fill fountain pens of this kind with a dense,
  • One object of the invention is to satisfy both contrary requirements. With this object in view the pulpy ink is made of a mixture of two inthe same quantity of glycerine and to the solution 35 to 40 per cent viscous dextrin is added,
  • the ball has to apply the pulp in a very thin layer to the paper, as otherwise the latter cannot absorb the whole fluid contents of the pulp and the written text will not dry.
  • thin layer has the further advantage that the I consumption is low and thus one filling may be used for a very long time. Consequently, to this pulp a fountain pen is employed the writing ball of which is in contact with its bearing along two circles only and by this a relatively tight mounting of the ball is attained, so that the same may gredients, one of which is a quickly drying visj cous material and the other one a, non-drying, preferably even hygroscopic liquid. Both materials should be of such nature that they can be easily separated from each other by physical means.
  • the quantity of pulpy ink remaining around the ball after writing does not dry, but is maintained moist as it contains a non-drying liquid, while the nondrying ingredient of the ink will be immediately absorbed by the paper during writing and thus is it removed from the pulp and the remaining other ingredient will quickly dry.
  • Every writing surface employed in practice shows a certain absorptive power for moisture which affords the absorption of the small moisture contents of the p p-
  • the viscous (pulpy) drying material may be for instance glue or a polysaccharid and the nondrying liquid may be cholesterised oil or for example glycerine.
  • a fatty material or at least a material having the properties of fats as such materials lubricate .
  • the pulp is made for example in such a manner that a powdery aniline color is dissolved in about always surrounded by the moist pulp.
  • the fountain pen is provided with a container for the pulp, which may be easily interchanged and thus after the consumption of the pulp contents of the pen the empty container is cast on" and is substituted by another container filled in the factory.
  • the annexed drawing illustrates by way of example three embodiments of the fountain pen constructed in accordance with the invention.
  • Fig. 1 represents an enlarged axial section of the first embodiment.
  • Fig. 2 is a sectional view of the container of the pulpy ink.
  • Figs. 3 and 4 are axial sections of two other embodiments equally on an enlarged scale.
  • Fig. 5 represents the writing ball and.
  • the outer part of the fountain pen is constituted by a hollow body I, on one end of which a closing member 2 is fastened by its threads.
  • the latter contains a sleeve 3 and a relatively wide channel 4; in the interior of which the pulpy material is forwarded to a head portion 5 of metal in the centre of which there is a tighter channel-6.
  • a small ball 8 can freely rotate.
  • the end portion 6' of the channel 6 is sufiiciently tight to be able to hold the ball 8.
  • a tube portion 9 is contained, which is preferably made of metal and constitutes an interchangeable container for the pulpy ink.
  • the threaded hole of the covering part In of this container is closed by a stopper before use.
  • the closing member 2 is screwed off, so that together with this portion also the empty container is pulled away from sleeve 1.
  • the stopper is removed from the covering part I of the new container, whereafter it may be screwed onto the extension II of sleeve 3 and introduced into the fountain pen together with the closing member 2.
  • These grooves may be constituted for example by two longitudinal ribs of the metallic tube 9, which are opposite to one another.
  • the piston I2 is provided with internal threads and it is screwed to a bolt l4, the end of which being without the tube 9 and being provided with ribs,'by
  • a rotatable sleeve I6 which it is connected to a rotatable sleeve I6.
  • This sleeve is mounted at the bottom of the fountain pen and has a handle member I! which is accessible after removing the closing cap I8.
  • a piston 20 is shiftable, which is pressed by a spring 2
  • the upper end 22 of the bolt I4 does not extend to the bottom of the container 9, but it bears on the covering part Ill of the container 9 by means of an elastic stop 22' in order not to hinder the action of spring 2
  • Thi end of the bolt I4 is not threaded in order that the piston I2, at the end of its stroke, should no longer engage the bolt.
  • is arranged behind the bolt 14 it is possible to employ a short spring and a long container which can receive much pulp. If the container 9 is filled with pulpy ink, an axial pressure is exerted on the piston I2 by the bolt I4 so that the pulpy ink is maintained under pressure. After consumption of a certain quantity of the pulpy ink, the spring 2
  • a slight disadvantage of the described embodiment consists in that when the container is empty, the bolt I4 cannot be used either, as it is not possible to screw the same into another full con- Ill tainer. Consequently, at this embodiment the spare containers are to be sold with a bolt I.
  • This drawback is not present in the embodiment represented in Fig. 3.
  • the screw 23 is integral with the bolt 24, which is rotatable in the protecting cap III of the fountain pen. The bolt 23 moves the nut 25 in axial direction, and the nut is guided by bars 26 and 26 being in the hollow body I of the fountain pen.
  • the nut 25 is connected by means of a cap-like member 21 to a hollow bolt 28 which actuates the piston I2 01 the container 9 for the pulpy ink, whereby between the nut 25 and the hollow bolt 28 a spiral spring 29 is inserted.
  • Fig. 3 shows the piston 12 at the end of its stroke. If the container 9 is filled with ink and the piston I2 is at the bottom of the container, also the nut 25 is situated at the lower end of the bolt 23 and the latter extends to the bottom of the hollow bolt 28
  • This fountain pen works in a similar manner as the embodiment according to Fig. 1, the main difference consisting in that when the container 9 is empty and is thrown away, only the piston I2 is to be cast off therewith, while the bolt 23 remains in the fountain pen. Before inserting the new container of pulpy ink into the fountain pen the bolt 23 is to be turned until the nut 25 is brought to its lower extreme position.
  • Fig. 4 The embodiment represented in Fig. 4 is similar to the construction shown in Fig. 3, however, it differs from the'same in that it allows a lengthening of the tube-like container 9.
  • a sleeve 30 provided with inner threads is employed, which operates another sleeve 3I provided with outer threads.
  • the latter is rigidly connected with a cap 32 guided in the hollow body I in lengthwise direction, furthermore with a bolt 33, on the end of which a rotatable connecting member 34 is mounted; the latter transfers the pressure of spring 35 to the piston I-2 of the container 9.
  • the container 9 is filled with pulpy ink, the whole sleeve 3
  • a fountain pen with a rotatably mounted small ball as writing means for pulpy ink
  • an interchangeable container for the pulpy ink a piston in the said container for pressing the pulpy ink forward
  • a screw bolt screwed into the said piston and adapted to forward the said piston if rotated, the end of the said screw bolt projecting out of the said piston and of the said container, a spring acting onto the said end of the screw bolt and adapted to hold the pulpy ink under pressure
  • the said container being adapted to be terchangeable tube like container for the pulpy ink in the barrel
  • a piston in the said container for pressing the pulpy ink forward means for exerting pressure on the said piston including a rotatable driving sleeve mounted at the inner end of the barreland provided with inner threads, a driven sleeve provided with outer threads and in threaded engagement within the driving sleeve, a cap member mounted on said driven sleeve, a bolt on the outer end of said driven sle
