Application filed March 7, 1927. Serial No. 173,571.

. uniformly. supplying the ink to the pen point irrespective ofthe position or angle 1 at which the pen is heldin the hand of the user, thereby permitting effective use of the {pm by persons writing in different fashions. A urther objectv o the invention is the r'ovision vof novel means for forming the 2 eeder bar, so that a quantity of ink will be held thereby at all times, so that the pen can be efliciently used by fast writers. r A' further object of the invention is the provision of a feeder bar for fountain pens, havin a novel arcuated chamber or passage exten ing transversely thereof adjacent the forward end of the bar constituting wells for holding a supply of ink, whereby ink will be quickly delivered to the pointeven after the pen has been held in an upright position for a considerable length of time.

A further object of the invention is the provision ofnovel means for delivering the ink to the chamber or well so as to insure an adequate supply thereto.

A further object of the invention is the provision of a pair of longitudiiial passages .formed in the feeder bar, one of which leads directly to the chambers or wells for suplying ink thereto and the other te minatmg short ofthe chambers or wells or supplying the ink directly to the pen point or nib.

A further object of the invention is to provide an improved-feeder bar of the above construction, which will be durable and efiicient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

, Other objects of the invention are to provide a feeder bar, that will prevent leakage of ink; a feeder bar that will provide a 'dr joint and a wet point; a feeder bar that wi L sucki back ink from the tip of the pen point 5 when the pen is held at an angle, point down;

a feeder bar that will positively hold the ink until the tip' of the pen point is touched; a feeder bar that will prevent ink from leaking when the pen is being carried in the pocket or otherwise when not in use.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a fragmentary longitudinal section through a fountain pen with the improved feeder bar. incor orated therewith,

Figure 2 is a top p an view of the improved feeder bar,

Fi ure 3 is a transverse section taken on the line 33 of Figure 2 looking in the direction of the arrows showing the formation of the longitudinal passages, 76

Fi ure 4. is-a transverse section through the fiaeder bar adjacent to the forward end thereof taken on the line 4--4 of Figure 2 looking in the direction of the arrows illus trating the formation of the ink wells or chambers, and

.Figure 5 is a transverse section taken on the line 5-5 of Figure 2 looking in the direcceives the feeder bar B and the pen 'polnt or nib 14. The pen point or nib 14.can be of the usual or any preferred construction.

The salient feature of this invention resides in the novel feederbar B which com- "prises the cylindrical shank 15 having the lower face thereof at itsforWa-rd end cut away and arcuated as at 16 and its forward end tapered to form a point 17 The upper face of the feeder bar B adjacent to the forward end thereof is provided with an arcuate slot 18 which extends transversely of thefeede'r bar. This slot 18 11 0 i is cut inwardly and downwardly and combar is an ink feed vides means for feeding ink 21' will function municates with a transverse bore 19 throughout the entire length thereof. The opposite ends of this bor'e19 are flared as at 20 which forms wells or chambers for the ink.

Extending longitudinally of the feeder groove 21, which opens out through the rear end of the feeder bar. This groove 21 is formed relatively deep and is provided with a central rib 22 which terminates short ofv the'upper face of the feeder bar. This rib 22 divides the grooves into a pair of

ink passageways

23 and 24 respectively. The ink passageway 24 terminates short ofthe slot 18, while the passageway 23 communicates with the slot and prothereto.

Thus it can be seen that these passageways 23 and 24.respectively act as means for supplying ink to the passageways or slots and directly to the pen point or jnib.

In rear of the slot 18, the upper face of the feeder bar B is provided with a transversely extending arcuate groove 25. This groove is semi-circular shaped in cross sec tion and extends from one side of. the bar to the? other. This 'groove'is of a less depth than the groove 21 and the groove 21 serves as means for .supplyin ink thereto, but in view of the fact that t e groove 21 is of a greater depth than the groove 25, the groove to supply ink to the bar aheadof said groove 25.

In operation of the improved feeder bar,

the same is inserted in the ink feed section 11 and the. pen'point 14 is placedain posit1on on the feeder bar between the same and the ink section 11. This ink will now flow along the

passageways

23 and 24 and fill the groove 25, the slot 18 and the wells 19 and 20. The groove 25, slot 18 and the wells will serve as means for'retarding the *flow of ink and means for distributing the ink uniformly to the pen nib or point. It is obvious that when the pen is held in an upright position that a certain amount of ink will be retained in the wells 19 and 20 so that when the pen is again turned down for use, an immediate supply of ink will be available for the pen oint. It is also obvious that owing to t 6 formation of the quantity wells, and the slot 18 that a'suflicient supply of will be retained in the feeder bar so that irrespective how fast the person may be writing with the pen, a suflicient or ink will be supplied to the Pd a a a Changes in details may be made without departing from the spirit or scope of this invention, but:

What I claim as new is:

1. A feeder bar for fountain'pens comprising a body having its forward end tapered and rounded to a point, and provided with a transverse bore adjacent to the point and a longitudinally extending ink passageway, the terminals of the transverse bore being flared outwardly defining ink distributing and retaining wells, and the body also having a transversely extending arcuate slot conforming to the curvature of the forward end of the body extending inwardly and rearwardly and communicating with the transverse bore throughout the length thereof.

2. A feeder bar for fountain pens comprising a body'having its forward end tapered and rounded to define a point and provided with a transverse bore and a longitudinally extending ink passageway opening out through the rear end of the body, the terminals of the bore being flared to define ink distributing and retaining wells, the body also having an arcuate transversely extending slot extending inwardly and rearwardly communicating with the bore throughout the entire length thereof and a groove in rear of the bore communicating with the longitudinal ink passageway the groove being of a less depth than the longitudinal passageway.

3. A feeder bar for fountain ens comprising a body having its in ward end tapered and rounded to provide point, and provided with a transverse bore and a longitudinal groove opening out through the rear end of the body, the outer ends of the bore being flared to define ink distributing and retaining wells, said body its forwardend a transverse slot extending inwardly and rearwardly communicating with the bore, and a rib in saidslot defining a pair of. ink passageways, one of said passageways terminating short of the slot and the other communicating therewith.

4. A feeder bar for fountain pens comprising abody having a transverse bore, and a longitudinally extending ink passageway opening out through the rear end of the body, the body also having a transversely extending arcuate slot extending inwardly and rearwardly and communicating with the bore throughout the length thereof, the longitudinally extending passageway communicating with the central portion of said arcuate slot.

. In testimony whereof I-afiix my signature.
