Description:

My invention relates to improvements in four tain pens, and the general object of my Inventio is to provide a greater ink storage capacity fc the fountain pen.

Another object of my invention is to provid means for filling the ink container of the foun tain pen.

A further object of my invention resides in th novel form and construction of the pen bods whereby only the writing point of the pen is ex posed to the outer air when the pen is in use.

Still another object of my invention resides ii the novel ink wick construction and operation whereby the ink is kept in uniform flow as close t( the point of the pen as is practicable.

My invention has other minor objects, all oJ which will be clearly understood from a perusal of the following detailed description, taken in connection with the accompanying drawing, and in the drawing: Figure 1 is a longitudinal sectional view of my fountain pen by itself, the view being-in broken formation to facilitate illustration, the pen being ready for use on removal of the protecting closure.

Figure 2 is a cross-sectional view on an enlarged scale of Figure 1, the view being had on the line 2-2 of Figure 1.

Figure 3 is a view of one side of a pen, per se. Figure 4 is an enlarged side view of the pen nib, opposite to that shown in Figure 3.

Figure 5 is an enlarged end view of the pen nib, and Figure 6 is an enlarged detail cross-sectional view of the pen nib, had on the line 6-6, Figure 3.

Referring now in detail to the drawing, and wherein like parts are designated by like numerals, the barrel I of my fountain pen is preferably made of transparent material, or partly of such material, so as to enable the user to see the amount of ink in the container. One end of the barrel is threadedly engaged, as shown in Figure 1, to a thimble 2, carrying a check valve 3, of ball or any preferred type, and normally seated over the valve duct 4. A cap 5 is threadedly secured to the outer end of the thimble and fastened to the cap is a piece of rubber 6 or the like of resilient nature, which serves to hold the valve 3 firmly in place when the cap 5 is screwed down tightly.

Fastened in the opposite end of the barrel I is a plug 7 which is tapered as shown and over this tapered portion is secured a transparent nipple 8, the extremity thereof carrying a metallic member 9 with an opening through which projects the i- pen nib 10 of any preferred type of pen. The n upper portion of the nib 10 is seated in a recess or in the plug as shown in Figures 1 and 2 and partially embraces a tongue 13, carried by the plug 7.

le Thus the space between the thimble 2 and the - inner end of the plug 7 provides an ink container R of relatively large capacity.

e Attention is here directed to the fact that the nib of the pen is on a plane directly in line with Sthe opening A in the member 9, hence the writ- 1o ing point of the pen is centralized in the pen, Ssimilar to a lead pencil and the pen is not held off-center as in ordinary fountain pens and pen Sholders. This makes for easier writing. In the drawing, Figure 1, the ball point of the pen is r drawn larger than actual size to facilitate clearness, but in reality the ball point is small enough to pass through the opening A when replacing, or Staking off the nipple 8 to fill pen or any other purpose. Thopening A is large enough also to permit some play of the pen nib. Also in addition to the customary slit II' there is a slit II" at right angles thereto.

Spaced from the nipple 8 is a transparent closure nipple 14 threadedly engaged to the barrel I, as clearly shown in Figure 1. Apertures B permit air to enter the nipple 8 to prevent clogging the ink duct 15. Thus the nipples 14 and 8 provide a stream-line effect to the pen, the result being a more graceful appearance. An ink wick support C holds a wick 16 which latter traverses the ink duct 15 and maintains an even flow of ink almost to the pen point. D is a spring clip of well known construction for attachment to the user's pocket. The pump and pencil unit attached thereto likewise carry a spring clip, not shown.

From the foregoing it will now be apparent that when the nipple 14 Is removed, only the extreme end of the pen point is exposed, hence the tendency of dust or foreign matter to clog the pen is greatly reduced. Again, in using a fountain pen, after the protective cover is removed, should the pen remain in this condition a few minutes without being used, the ink being in contact with the outer air becomes dry and it is necessary to shake the pen to force the ink downwardly onto the point again. In the present construction this is also greatly reduced.

While the foregoing describes a practical working embodiment of my invention, I desire it understood that I do not limit my invention to the precise construction shown and described, as my invention is capable of modifications and alterations in keeping with the spirit thereof and within the scope of the appended claim.

What I claim as new is: In a fountain pen comprising a transparent ink barrel, a plug member secured to the lower end of the barrel, said plug menber having a tongue-like extension disposed off center or eccentrically of the plug member, and a recess in the plug member for seating the pen nib, whereby the latter is held in the recess and partially embraces said tongue-like extension, said fountain pen including a transparent tapered nipple secured over the said plug member, said tapered transparent nipple having a piece of metal forming its lower end and provided with an aperture through which only the writing point of the pen extends, an ink duct extending through the said plug member from the said nib to and communicating with the transparent ink barrel, an ink wick extending from the nib through the ink duct in the plug member and reaching into the upper end of the ink barrel, and a support member being secured to the inner end of the tongue-like extension and extending into the ink barrel for the support of the said wick element.
