6 Claims.

The present invention relates to improvements in fountain pens.

The primary object of the invention is to provide a pen that will contain ink of several differant colors and present novel valve means for selecting the desired color of ink to be used.

A further object of the invention is the construction and arrangement of a rotatable disc and valve closely associated with the discharge ends of the ink-carrying reservoirs and pen point, whereby when one color of ink is selected for use the other color will be forced back into its reservoir, thus alleviating any possibility of the ink becoming mixed.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application.

In the drawing:

Fig. 1 is a transverse sectional view of the new and improved pen and illustrating 'in plan the ink carrying reservoirs.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is a perspective view of the parts forming the valve means for selecting and controlling the desired color of ink to be used.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1; and

Fig. 5 is a diagrammatic view illustrating the movement of the eccentrically mounted valve with respect to the discharge opening.

Referring to Fig. 1 of the drawing, it will be noted that the invention comprises a barrel 6 :40 two reservoirs, but it is to be understood that any desired number can be effectively used without departing from the spirit of the invention.

Each of the reservoirs may be supplied with ink thru the use of the usual filling means including the pivoted arm I engaging with the longitudinal compressing member II. When replenishing the supply of ink in each reservoir it will of course be necessary to control the valve selecting means to be later described.

Mounted within the barrel 6 and adjacent the discharge end of the collapsible reservoirs 8 and 9, is a plug member I2. The ends of said reservoirs engage upstanding shoulder portions I3 of the plug member I2 and the ink is fed to the pen thru the channels I4 and I from the reservoirs 8 and 9, respectively, the said channels being formed within the body of the plug member I2.

Positioned adjacent the plug member I2 is the feeding head I6 constructed with a recess l1 and supporting feed troughs I8 and I9 directly connected to the channels I4 and I5 of the reservoirs 8 and 9, respectively. The feed troughs I8 and I9 are supported from shoulder portions depending from the plug member I2 and upstanding shoulder portions forming a part of the feeding head.

Centrally disposed within the feeding head I6 and directly connected to said troughs I8 and I9 is the member which aids in supporting the pen point if and thru which the supply of ink is fed to said pen point. A pair of channels 22 and 23 have communication with the feed troughs I8 and I9 and are controlled by the means illustrated in Fig. 3 of the drawing. The valve controlling means comprises the rotatable disc 2 3 provided with recesses 25 and 26 adapted to be aligned with the feed troughs I8 and I9, respectively, depending upon the desired color of ink to be used. The disc 24 is rotatably mounted Within the body portion of the member 28 and is positioned in close proximity to the discharge ends of the feed troughs I8 and I9, as illustrated in Fig. l of the drawing. Means for controlling the rotation of the disc 24 includes the transversely disposed rod 21 secured within the upstanding portion 28 of the valve disc 24. The rod 27 extends transversely thru the barrel of the pen and has its opposite end passing thru the end of the barrel and connected to a knurled nut 29 for controlling the rotation thereof.

The other portion ofthe valve controlling 0 means comprises the cone-shaped valve 30 connected to the disc 24 thru the medium of the connecting rod 3i, the upper end of which is secured within a recess in the bottom portion of the valve disc 24 so that said disc 24 and cone valve 38 will rotate in unison.

Diagonally disposed and at diametrically opposite points within the cone-shaped valve 38 are a pair of channels 32 and 33 adapted to align with 7 the openings 25 and 26, respectively, of the valve disc 24 for controlling the selected color of ink to be fed to the pen point 2 I. It is to be understood that the valve disc 24 and valve 36 will rotate in unison upon turning of the knurled nut 29 so that Z ink will flow from a selected reservoir thru its respective channel into the feeding head I6 and thence thru either channel 22 or 23 to the pen point 2|.

Integral with the body portion of the valve 30 and eccentrically disposed relative thereto is the controlling member 34 which rotates within the recess 35 of the member 20. The member 34 is so mounted that upon rotation of the valve means, ink will be supplied to the pen and the ink of the opposite color will be forced back into its reservoir so as to prevent a mixing of the several colored inks. This can readily be determined by referring to Figs. 1 and of the drawing. In Fig. 1 the respective channels are open so that a supply of ink will be fed to the pen point 2! from the ink supplying reservoir 9. During the rotation of the rod 21 and its supporting valve disc 24 and cone 36 to select an ink, the ink which normally would remain in the channel 35 that has been fed from the reservoir 8 will be forced back- Wardly and up into the channel 22. It is to be understood that this action will occur when the various parts are rotated so that the member 34 a has assumed the position illustrated in Fig. 1. The converse is true if it is desired to supply ink fromthe reservoir 8. The action of the member 34 can be determined by an inspection of the illustration in Fig. 5 of the drawing. The center of rotation of the disc 24 and valve 30 is indicated by the letter A and the angle of rotation is confined by the radial lines projecting from the point A. Due to the eccentricity of the member 34 the center of same will be caused to swing from the point B to the point C, thereby moving the opposite side of said member into contact with the opposite Wall of the recess 35 in which it is contained, thuscausing the ink therein to be squeezed out.

The feeding head MS is provided with the usual longitudinal thread portion 36 for attaching the cap Bl for protecting the pen when not in use.

It is believed that the operation of the device is clearly evident from the above description. In use, different colored inks, for example, red and black, may be contained within the reservoirs 8 and 9, respectively. When it is desired to use.

the pen for writing with black ink the knurled portion 29 is engaged by the fingers and rotated a degree sufficient to provide a continuous discharge channel from the reservoir 9 thru the channels i 5, I9 and 23, respectively. Rotation f the knurled portion 29 will cause the: valve disc 25 and valve 30 to rotate so as to align their respective openings 26 and 33 with the feed channel i 9. If the pen had previously been used for writing with red ink, the residue in the channel 35 will be squeezed or forced back into the channel 22, thus preventing a mixing of the inks.

It is to be understood that this improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.
