Definitions

  • the invention relates to a fountain pen having a chamber adapted for the insertion of solid ink from the outside.
  • Fountain pens of the kind "referred to are 5. known in which the chamber for the ink pencil communicates on the one hand by means of a capillary transverse opening with the feed-line of the writing nib and on the other hand issues towards the outside in such a manner as to enable the pencil to be inserted into the chamber mentioned.
  • the said known types of fountain pen operate in such a manner that the-water introduced into the space for the storage of liquid dissolves, in the course of its flow to the writing nib along the feed line referred to, certain parts of the ink pencil, and thus reaches the writing nib in the form of coloured ink.
  • the said known type of construction possesses various drawbacks. In the first place, it will hardly permit the complete utilisation of the solid ink because a part of the same will always remain in an undissolved condition in the filling chamber mentioned.
  • Another drawback of this type of design consists in that manufacturing of the capillary opening extending in the transverse di-,
  • the first object achieved by means of the in vention is that the solid ink pushed directly through the filling canal into the space for the storage of liquid will be dissolved in' its total extent by the liquid available in-said space so that leading to the writing nib; accordingly, fountain April 23, 1938 it is not liquid to be coloured in the course of its path of flow to the writing nib but liquid ink already completely coloured that will pass from the space for the storage of liquid into the feed-' a line leading to the writing nib.
  • This arrangement will ensure the perfectly uniform intensity of the colour of the writing ink during the whole time, during which the store of liquid lasts, and will at the same time also enable a more simple type of construction to be obtained, as it dispenses with the capillary opening for the transverse connection of the filling chamber with the feed-line as used in constructions hitherto known.
  • the invention also offers advantages of fundamental importance regarding the method of working because atmospheric pressure will, through the filling canal according to the invention, exercise its effects in the space for the storage' of liquid in the sense that it will tend to provement to be obtained in fountain pens of a cheaper type of design which, as well known, are owing to their less precise construction frequently presenting the tendency of failing to operate,
  • the filling canal according to the invention will enable fountain pens of a cheaper type to practically write just as uniform and start-just as promptly as fountain pens of a more precise type which are, as is well known, many times as expensive.
  • the invention is based is that, in case a filling canal is provided which issues directly from the outside into the space for the storage of liquid, the said liquid'will neither flow out nor leak cut, provided that the filling canal is constructed of a so small diameter, of 'the order of magnitude of about 1 mm., as required for the pushing-in of ink pencils, because a filling canal of the said diameter will still work in the manner of a capillary opening and, moreover, atmospheric pressure will counteract any flowing or leaking out of the'liquid.
  • Figure 1 is a longitudinal section of the device.
  • Figure 2 is a similar section of a modification in which the solid ink filling canal or chamber is diiferently located and a sac is utilized;
  • a denotes the writing nib
  • b the penholder
  • d the usual space for the-storage of liquid
  • g an inserted plug
  • the feedline 91 conducting the liquid from the space d to the writing nib a is provided in the form of of which issues directly into the space d for the storage of liquid whilst its other end issues freely towards the outside.
  • the solid ink inserted into the canal a: or set on to its external mouth can be pushed from outside directly into the space (1 for the storage of liquid through the canal g: by any desired means, e. g. by means of a thin metal rod.
  • Fig. 2 differs from that according to Fig. l, in thefirst place, by the fact that the filling canal or for the solid ink is not provided on the cylindrical surface of the inserted plug g in the form of a groove open on-one side but it constitutes a longitudinal borehole; moreover, Fig. 2 illustrates the rod k. already mentioned in connection with Fig. l; and serving for pushing the solid inkinto the space d for the storage of liquid, which latter is possesses such a length as to enable the solid ink to be pushed by hand, by means of the said push rod k, through the canal 92 into the liquid space d.
  • the push rod is preferably constructed so as to possess a diameter smaller by, for instance about 0.1 to 0.2 him, than the filling canal ya, so as to ensure that it will be possible for atmospheric air 'to leak through the filling canal 92 into the space d for the storage or liquid also when and if the push rod is is situated in the interior of the filling canal g2. Dropping out of the push rod R: from the filling canal g2 during the process of writing may be prevented in any way desired,
  • the rod is slightly bent so that it will fix itself resiliently in the straight bore-hole 0:.
  • the filling of the liquid space d with liquid can be effected by means of any pumping device of a known typesuitable for this purpose, and in view hereof this part of the fountain pen has not been represented on the drawing at all.
  • Another important advantage ofiered by the invention is that it is also possible to, flt existing fountain pens subsequently with the filling canal g2 according to the invention which measure will, as already men ioned, result, particularly in the case of fountain pens of a cheaper and less precise type, in a' quite surprising improvement of their operation. 4
  • Another advantage of the fountain pen-according to the invention consists in the fact that it can be used without any alteration for liquid ink as well as for solid ink, in which latter case as. 'liquid preferably ordinary water is employed.
  • the solid ink to be used must not be in the form of ink pencil but it may be granulated or-in any other form of small particles or gran-
  • the invention may be carried into effect in a many ways difiering from the embodiments illus trated by way of example.
  • a device of the character described comprising a fountain pen having a chamber adapted "for the insertion of solid ink from theoutsidc.
  • the said chamber constitutes a filling: canal issuing by its inner end directly into the space for the storage of liquid of the penholder, the said canal being of such form as to enable the ARTHURBALAZS.
