FOU NTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 397,413, dated February 5, 1889. Application filed September l, 1888. Serial No. 284,369. (No model.)

T all 1071.071?, it may concern.-

Be it known that I, THEoDoRE FREDERICK BOURNE, of Clifton, Richmond county, New York, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

The object of my invention is to provide a fountain-pen that shall be simple in construction and not liable to get out of order.

ro The invention consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specification,

3o 7. Fig. l0 is a cross-section. of the same on theline k b", Fig. 9. Fig. ll is a cross-section on the line 113'" k, Fig. 7.

.In the accompanying drawings, the letter A represents a barrel or ink-reservoir, and B represents a neck or tube at one end of the barrel A and communicating with the interior of said barrel. The neck or tube B may be secured to the barrel A by means of serewthreads in said tube and barrel, or by other 4o means.

D represents a cap that adapted to lit over the neck or tube B to protect the pen E carried by the tube. Said cap may be placed at the free end of the ink-barrel when the pen is being used.

The above parts are of the ordinary or suitable construction.

F represents my improved feeder. The feeder F is constructed of a bar or rod of hard 5o rubber or other suitable material. As shown in Fig. l, the feeder-bar F passes through the neck or tube B and extends from both ends of said tube, thereby forming a plug in the neck B; but the feeder-barfneed not extend from the inner end of the neck B, if preferred. 5 5 The feeder-bar F, as shown in Fig. l, iits closely Within the neck or tube B, so as to prevent ink passing between the feeder-bar and the neck, and thus escaping. The lower end of the feeder has an extended arm, f,one 6o side of which is attened to form a recess, f adapted to receive the pen. Vhen in position in the holder, the heel of the pen E Will pass Within the neck or tube B, the pen lying on the flattened portion of the arm f of the feeder-bar F and in close cont-act therewith. As shown in the drawings, the outer or free end of the feeder-bar F terminates near the end of the nibs of the pen. The ink from the holder or barrel A is fed to the pen along the 7o feeder-bar F.

For the purpose of conducting ink to the pen E in the proper quantity, I provide a groove, a, in the feeder-bar F, part of which groove comes directly beneath the pen. The 7 5 part of the groove a on the side of the bar F that is next to the pen I make straight, as shown, for a distance-*say nearly to the heel or butt-end of the pen, although the straight part of the groove may extend slightly farther 8o along the feeder-bar than the heel of the pen.

As Will be seen, the straight part of the groove d in the feeder-bar does not enter the ink barrel or reservoir. From the point Where the straight part of the groove ends, near the heel of the pen, said groove extends in a spiral form around the feeder-bar, so as to communicate Withthe lnk in the barrel or reservoir. As shown, the spiral part of the groove is against the inner Wall of the neck or tube B, 9o the tube thereby covering the groove, and thus forming a spiral channel for the passage of the ink from the barrel to the part of the groove beneath the pen. By making the feeder-bar `F lit closely within the neck or tube B the ink on the feeder is coniined in the spiral groove or channel, and thereby prevented passing along the sides of the feederbar, and thus escaping. As shown in the drawings, the straight part of the groove d' roo that is beneath the pen terminates close to the outer end of the feeder-bar, a small amount along the channel.

of material being lett between. the end of the groove and the end ot the feeder to prevent ink flowing ot't' the end of the Vfeed er-bar when using the pen. lVhen the pen is in usc, the ink passes from the barrel along the spiral groove to the straight part of the groove, and thence upon the nibs el' the pen. The ink tinds its way along the groove (t by capillary attraction and by gravity. The action ot the nibs of the pen in writing also serves to draw ink along the groove a to supply the pen.

In order to supply the barrel or reservoirA with air as ink vis witlulrawn l'rom the barrel, so as to keep up an equililnium in thel barrel, I may pert'orate the feeder-bar F longitudinally, as at l), Fig. 2, said perforation extending from the outer part ol' the [feeder-bar to its inner end, where it,- opens into the barrel or reservoir; but the air-duct l; could. be in the form ot a spiral or other groove on the outer side ot' the totaler-bar F, as shown in full lines in Fig. (5. By making a spiral channel or duct for the ink any air that may pass along the channel with the outgoing ink will not have a 'free and iiininteriuipted straight course from the barrel, and thereby be perinitted to torce too much ink. to the pen, but said air will meet with a resistance in the curved walls of the channel, and thereby be prevented from t'orcin g the ink too freely This construction will be found of advantage when the barrel is nearly empty ot' ink and when a comparativelylarge quantity of air is in the barrel,whieh air will be caused to expand by the heat ot. the hand of the person using' the pen.

In Figs. l to 6 I have shown thet'eeder-bar F, having the groove u,to be in one piece and .fitting closely within the neck or tube l5 to foi-1n a plug therein; but it is evident that the groove c may be in a bar separate from the plug for the neck.. This construction is shown in Figs. 7 to Ill. In said rtigures the feeder-bar F is a comparatively slender rod that extends along the inner wall of the neck or tube B. This slender rod F is provided wit-h the groove c, the straight part of said groove being directly beneath the pen E, while the spiral part ol' the groove a extends around the feeder-bar and leads toward the ink in the barrel A.

FE is a plug that I place in the neck or tube B, so as to till said tube and prevent ink flowing from the barrel. A. On one side of this plug F2 is formed a longitudinal groove, (l, in which I place the slender feederbar F, as shown in Figs. 9 and ll. The bar F preferably lits closely in the groove d, so that the walls ot' the groove d will cover part ot the spiral portion oit the groove (t. The upper side of the feeder-bar F also lies against the inner wall ofthe tube Il, (see Fig. S,) so that the wall of the tube .l may cover part ot the groove a, to prevent the escape ot.' ink along 'the sides of the feeder-bar.

In order to admit air to the barrel A, I may perforate the separate plug F2 longitudinally, similarly to that shownin Figs. 2 andv 3, or I may provide a groove, b, in the plug F2, as in Figs. S, 10, and il. The passage ot' the ink along this slender feeder-bar is the same as that heretofore described. It is evident that the groove (I could be replacedby a longitudinal hole in the plu F2, and that the feeder-bar F could be passed into said hole, so that the walls ot the hole in the plug could cover the spiral groove.

Care should be taken that the part ot' the feeder-bar that tits agz'tinst the pen E to supply the pen with ink. troni its groove d should be in close contact with the pen to prevent ink passing' to the sides ol' the pen from between the li'ecder-bar and the pen.

Although I have shown the spiral groove as cxtendin entirely around the 'ee .le1ba'r, it is evident that the spiral groove may be carried partly around the feeder-bar on one side and then pass upwardly and inwardly along the saine side ol' the 'teedenbar or be otherwise suitably arranged. It is also vevident that the straight part ot the groove d could be dispensed with, the spiral groove or channel terminating at the pen. It preferred,thc neck or tube .l could be dispensed with and the feeder-bar be passed within. the barrel and closely tted therein, similar to its fitting in the tube B.

Ilfaving now described my invention, what I claim isl. An ink-feeder for al'ountain-pen having the flattened. portion adapted to bear directly against the inner side of the pen, and the groove or channel made spi rally around the feeder and extending to the :flattened portion thereof, and thereby adapted to feed ink to the pen, substantially as d escribed.

2. An ink-feeder having the extended arln,

against which the pen is adapted to press,

and the groove or channel made spirally around the feeder and extending longitudr nally on the arm on the side next the pen, and the longitudinal air-inlet aperture extending through the feeder and communicating with the interior of the barrel, substantially as described.

In a fountain-pen, the combination of the barrel or reservoir, the neck or tube' therein at one end, the feeder extending through and lIitting in the neel; or tube and entering the barrel, said feeder having the exterior spiral groove or channel, and the pen clamped in a recess in one side of the feeder between the latter and the neck and having its inner side communicating with the groove or channel, substantially as described.

4. In a fountain-pen, the combination, with a barrel and pen, ol' a feeder carried by said barrel and consisting of a bar having a groove that is straight on the side next to the pen and that extends from thence in a spiral along the bar toward the ink, substantially as described.

5. In a fountaiirpcn, the barrel A, having tube B and the independent and removable IOO IIO
