Allg- 14, 1945- M. GERGELY CARTRIDGE FOUNTAIN PEN Filed June 29, 1945 )11,46% llllll.
I n ven tor Patented Aug. 7, 1945 UNITED STATES PATENT UFFICE 1 Claim.
This invention relates to new and useful improvements in fountain pens and more particularly to fountain pens of the readily replaceable ink supply type.
The principal object of the present invention is to provide a fountain pen which broadly consists of a pen point holder section and a re' Figure 1 represents` a longitudinal sectional view through the improved pen showing the screw type cartridge. Figure 2 is a section on the line 2-2 of Figure 1.
Figure 3 is a side elevational view of the cartridge.
y Figure 4 is a longitudinal sectional view l through a slip type cartridge.
Referring to the drawing wherein like numerals designate like parts, it can be seen in Figure 1, that numeral 5 denotes a pen point holding section, while numeral 6 denotes a cartridge for containing ink, this cartridge being readily replaceable and preferably of plastic or some other inexpensive material. 'I'he material of the cartridge 6 is preferably transparent.
The section 5 has a threaded bore 'I in one end thereof for receiving a threaded reduced extension 8 of the cartridge 6. A packing member 9 is provided and suitably seated at the inne end of the threaded bore 1.
Figure 1 further shows a pen point I0 and a feeder plug II which is disposed into a bore I2, and this feeder plug II has a tubular punch I3 extending from itsl inner end and capable of rupturing the reduced end portion 8 of the cartridge 6 when the cartridge 6 is screwed into the socket 1, it being shown that the inner end of the tube I3 is sharpened as at I4.-
Thus it can be seen that when the cartridge has been ruptured, ink can ow through thev(ci. 12o-42) Figure 4 shows a slightly modified form of the invention, reference character 6a denoting a cartridge and this has a reduced smooth extension 8a which is adapted to be slipped into a 5 smooth bore 'la in a pen point holding section 5a,
this section having a tubular punch I3a capable of rupturing the reduced portion 8a of the cartridge 6a when the cartridge is forced into connection with the section 5a.
As can be seen in the drawing, the forms of the invention shown in Figures 1 and 4 have threads I1 and I8 at the inner end portions of t the cartridge so as to accommodate fountain pen covers (not shown).
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the. spirit and scope of the invention as 20 claimed hereinafter. Y
Having described the invention, claimed as newL is:
A fountain pen comprising a tubular pen point holding section having a counterbore at its upper end to provide an internal annular shoulder. an ink cartridge forming the handle of the pen and having 'a reduced normally closed cylindrical lower end removably tted and retained in said counter-bore. a packing washer seated on said shoulder and engaged by the lower end of the cartridge, a pen point and a feeder plug having their upper ends disposed in the lower portion of the pen point holding section, said feeder plug having an axial bore in its upper portion, a pocket intermediate its ends communicating with the lower end of said axial bore, and a longitudinal ink channel at the inner side ofthe pen point extending from the pocket to the lower end of the feeder plug, and a cylindrical tubular punch having its lower end fitted and secured in the axial bore of said feeder plug and projecting upwardly into the counter-boreof the pen point holding section so as to centrally puncture the lower end of the cartridge -when the latter is 4 acted into said counter-bore, said packing .washer having a central opening snugly receiving the upper end of the punch to prevent leakage of ink from the ink cartridge about said punch.
