Definitions

  • the present invention relates to fountain pens.
  • Fountain pens are already known which have two pen systems each of which is provided with a separate ink reservoir and filling mechanism and which are arranged so as to be axially displaceable in a casing which is open in front. By rotating a sleeve, one pen system is pushed forward into the working position and the other pen system is pushed correspondingly further rearwards into the casing.
  • the two pen systems move simultaneously and this construction requires the casing to be made longer than is really necessary because one pen system moves forward whilst the other, at the same time, moves backwards from a neutral position.
  • the subject matter of the present invention is a fountain pen having at least two pen systems which can be brought selectively into the work- ⁇ ing position and are each provided with a separate ink reservoir and filling mechanism and which are arranged so as to be axially displaceable in a casing that is open in front.
  • each of the pen systems is held in an inactive position by spring action and connected with abolt which pushes the respective system into its active position.
  • a stop device is provided which is common to all the pen systems and by means of which a pen system which has been pushed into the position of use is stopped against the action of the spring acting upon this pen system.
  • a common operating device which is adjustable for each pen system and movable into a neutral position, the lling mechanisms and their operating device being so constructed that the operating device can act only upon the filling mechanism of a pen system which is moved completely in the position of use.
  • the subject matter of the invention differs also from the known fountain pens with two pen systems in which the pen systems are moved by a rotatable sleeve, one pen system being moved forward whilst the other is moved backwards, by the fact that not only two but three or even four pen systems may be provided.
  • Fig. l is an axial section through a fountain pen with two pen systems which can be brought selectively into the working position and each of which is provided with a separate ink reservoir, the fountain pen being shown in a position in which one pen system is in the working position;
  • Fig. 2 is a part of an axial section through this fountain pen in a position in which the ink reservoir of one pen system is to be filled;
  • Figs. 3 and 4 show one of the springs in front and side elevation respectively;
  • Fig. 5 is an axial section through the rear end of this fountain pen in another position
  • Fig. 6 shows the setting of the operating device of the lling mechanism, in accordance with Fig. 5;
  • Fig. 7 shows the setting of the operating device of the filling mechanism, in accordance with Fig. 2;
  • Fig. 8 shows the setting of the operating device of the filling mechanism, in accordance with Fig. 1;
  • Fig. 9 is a section through a detail
  • Fig. 10 is a section on the line llll0 of Fig. 1;
  • Fig. 11 is a section on the line l l-l i of Fig. 1;
  • Fig. 12 is a section on the line l2-I2 of Fig. 1;
  • Fig. 13 is a plan View of the filling mechanism of a pen system.
  • each of these two pen systems can be brought selectively into the working position and each ⁇ of which is provided with a separate ink reservoir.
  • Each of these two pen systems has a body l of semicircular crosssection which has a cavity 2 that is intended for receiving the ink reservoir 3 which consists of a rubber sack.
  • This ink reservoir 3 is connected in from; to a nib holder ii which has aY passage through which the ink is led to the nib.
  • a nib holder ii which has aY passage through which the ink is led to the nib.
  • a bore which extends in the axial direction and in which a filling pin 5 is dsplaceably guided.
  • An opening in the body l is intended for the reception of a bolt 6 of the plate which serves for moving the pen system.
  • a guide piece 'I which serves for guiding the rear part projecting from the body I, of the lling pin 5, and for receiving and bearing against a compression spring 8, as well as a carrier for the abutment 9 for the return spring I6. which is represented in Figs. 3 and 4 in side and front elevation, has a semi-circular prole.
  • a locking sleeve l2 which surrounds the two pen systems and which has, at its rear end, two opposite slots I3 in the manner of a bayonet catch, is kept in its position by a spring I4'.
  • the slots I3 of this locking sleeve I2 co-operate with the bolt t of one pen system or with the bolt 6a cf the other pen system. If one of the pen systems is pushed into the position of use, the corresponding bolt 5 or @a is moved in a groove IT or I'I'a, which is arranged for this purpose in the casing of the fountain pen and extends in the axial direction.
  • the respective bolt enters one of the two slots I3 of the locking sleeve I2.
  • the pen system which is moved forward by means of the bolt 3 or 5a, reaches the position of use, the bolt 6 or Sa enters an enlarged portion of the corresponding slotl I3 and the locking sleeve I2 is rotated back under the action of the spring I4.
  • the bolts S or Eu abut slightly inclined shoulders I5, so that the respective bolt and, with it, the corresponding pen system are kept in this position.
  • each pen system For flattening the ink reservoir 3 for the purpose of lling it, there is provided for each pen system a strip I 8 which is movably connected, at the point 26, with a at spring I9, the front end of which is held in the nib carrier 4.
  • a stop 33 which is mounted on the pressing shank 26 and cooperates with the bearing bushing 28, determines the position of rest of the pressing shank 26 together with the Ipusher 30.
  • the pressing shank 25 with the pusher 30 is rotatably mounted.
  • a pin 34 (Figs. 2 and 5) which is so arranged and dimensioned that itl can enter one of two apertures 35 which are provided opposite to each other in the bearing bush 28.
  • the ink reservoir 3 of one or the other pen system can be -lled by operating this pusher 30, byy virtue of the fact that, in this way, the wing 25 that is mounted on the pressing shank 25 is brought intoV such a position that it acts upon the filling pin 5 of the corresponding pen system, the ⁇ ink reservoir of which is to belled.
  • Figs. 2 and 5 Fixed to the pusher 30 is a pin 34 (Figs. 2 and 5) which is so arranged and dimensioned that itl can enter one of two apertures 35 which are provided opposite to each other in the bearing bush 28.
  • the pusher 3o is, by the compression spring 2, one end of which is fastened to the bearing bush 28 and the other end tothe pusher 32, not only pressed back but also rotated back into its neutral posi-tionrepresented in Fig. 8, with the result that the wing 25y of the pressing shank 26 is likewise rotated back into the space 36.
  • the fountain pen may ⁇ contain three or evenfour pen systems instead of the exemplied two systems.
