1 Claims,
\ Another object is the provision in afountain pen of a simple and practical ink fee'd means which will keep the pen ready for writing without unnecessary prior manipulations to get the ink to flow to the nib, and which continuously feeds the ink as the result of a positive pumping action set up by the mere act of writing with the pen in'the usual manner.
A further object is the provision in a fountain pen of means which affords a nib vent and a forced ink feed, the latter feature being derived as the result of the flexing of the pen nib while writing with the pen in the usual manner.
A still further object is the provision of an inexpensive ink feeding means in a fountain pen which makes it a more satisfactory writing instrument.
The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which:
Figure 1 is a top view of the writing end of a fountain pen embodying the present invention.
Fig. 2 is a longitudinal section taken on the line 22 of Fig. 1.
Fig. 3 is a section showing the nib flexed as occurs when writing with the pen, and also showing ink in the passage of the feed.
Fig. 4 is a view similar to Fig. 3, but showing displacement of some of the ink out of the feed passage and onto the nib caused by reflex of the nib to a normal disposition.
In the drawing there is shown on an enlarged scale the writing portion of a conventional fountain pen. Referring now more particularly for the details of the invention it will be apparent that the parts of the pen shown consist of a barrel I 0 with a detachable end section II and connected fount or bladder l2 for the writing fluid or ink. An ink feed I3 and nib M in association with each other flt tightly in the bore of the section II which communicates with the interior of the bladder I2. The nib l4 may be of any type or style and be made of any suitable material or combination of materials, such as gold, steel, etc. The nib M has the usual slit I5.
The feed l3 has the usual longitudinally disposed 'flssured ink passage lfi whose inner end communicates with the bore in section I l and whose outer end terminates short of the outer extremity of the feed I3. Thus ink may flow from the bladder into the passage IS. The nib M has there- 5 through at onrear the end of the slit 15 a hole which admits airto the bladder through the passage lfiand bore of the end section so that the ink may flow out of the bladder in accordance with the usual practice. m
In accordance withv the invention use is made of a piece of tubular stock of any suitable maattached to the nib M. The eyelet ll preserves the usual vent and also provides means on the nib M consisting of a protuberance or projection I8 juxtaposed with respect to the passage It between the ends .thereof. The protuberance l8 approximates the'depth and width of the passage in order to act as a plunger in conjunction therewith. The protuberance moves into and out of the passage It as the nib M is flexed in opposite directions in writing with the pen in the usual manner. This augments or causes the flow of ink from the passage to the nib since there is set up a positive pumping action. The displacement of ink by the protuberance l8 takes place when the nib flexes toward the feed l3, and normal flow of the ink is possible when the nib flexes away from the feed l3. The ink in being displaced by the protuberance l8 will pass or stream 35 along the line of least resistance toward the point of the nib. Consequently there is a continuous supply of ink furnished to the nib. The means [8 also acts as a valve member or stop to retain some of the ink in the outlet end por- 40 tion of the passage l6 by preventing return flow thereof when the nib is normally unflexed while the pen is not in use. This will keep the pen ready and primed for writing the instant the 45 nib is brought into contact with the writing paper without unnecessary prior manipulations, shaking and coaxing.
It will be obvious that in attaching the. means I 8 coincidental with the usual air hole in the 50 nib that the essential'venting feature of the pen is preserved. It is to be understood however that the means l8 may be employed in conjunction with the nib and feed passage of the pen in any other way in which the result looked, 56
for may be attained without departing from the spirit of the invention, the scope of which is set forth in the appended claims.
What is "claimed is:
1. In a fountain pen, a feed having an ink passage therein, and a nib having means which is movable into and out of said passage to augment the flow of ink from the passage to the nib when flexing the nib while writing with the pen in the usual manner, said means having a vent to supply air to the fount of the pen.
2. In a fountain pen, a feed having an ink passage therein, and a nib having means which sets up a pumping action in conjunction with said passage to augment the flow of ink from the latter to the nib when flexing the nib while Writing with the pen in the usual manner, said means having a vent to supply air to the fount of the pen.
3. In a fountain pen, a feed having an ink fissure therein, and a nib having a protuberance approximating the depth and width of said fissure, said protuberance being movable into and out of said fissure to augment the fiow of ink 0 means movable into and out of said fissure to cause the flow of ink by displacement from the fissure to the nib when flexing the nib while writing with the pen in the usual manner.
5. In a fountain pen, an ink feed, a nib, and cooperative means consisting of a longitudinal ink fissure in said feed and an eyelet-like member on said nib to cause the flow of ink by a positive pumping action to the nib when flexing the nib in writing with the pen in the usual manner.
6. In a fountain pen, a feed having an ink passage therein, a nib, and a part which extends through the nib and the material of which is upstruck to secure said part to the nib, said part 7 being movable into and out of said passage to augment the flow of ink from said passage to said-nib when flexing the nib while writing with v the pen in the usual manner, said means also serving to retain some of the ink in the outlet end of the passage by preventing the return flow thereof when the pen is not in use.
'7, In a fountain pen, a feed having an ink fissure therein, a nib, and an element which extends through said nib and the material of which is upstruck to secure said element to the nib thus providing a vent and also means movable into and out of said fissure to cause the flow of ink by displacement from the fissure to the nib when flexing the nib while writing with the pen in the usual manner.
