To all whom. it may clone-ern:`

Be it known that I, OTToE. WEIDLICH, a vcitizen of the United vStates of America, and a resident of Cincinnati, in the county of' Hamilton and State of Ohio, have invented certain new andauseful Improvementsin Fountain- Pens, of which the following isa specification.

This invention relates to certain improvements in fountain-pens, and more particularly in the feeding devices commonly employed .therein for feeding the ink from the reservoir to the pen-point; and the object of the invention .is to improve and simplify theconstruction of such feeding devices in such a way as to afford means for preventing the dropping of ink from the` pen-point in case the inli'is fed too freely at times, whereby the operation of such feeding devices isimproved and the writing is rendered uniform and regular and blotting caused by suchy dropping ink from the pen-point is avoided. 1,

The invention consists in certain novel features of the construction, combination, and arrangement of theseveral parts of the improved feeding devices whereby certain .important advantages .are attained and the-devices are rendered simpler, cheaper, and otherwise better adapted and more convenient for use than variousother similar devices heretofore employed, all as Will'be hereinafter fully set forth.

The novel features of the inventionwillbe i carefullydefined in the claims.'

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is ay sectionalview taken axially through the end porl tion of a fountain-pen provided vwithffeeding devices embodying my invention and showing in elevation theupper face -of said feeding'devices. Fig. Qisa view similar to Fig 1, but

Fig. 4 is a view showing the feeding devices detached fromthe pen in sectional side elevation, the two end portions of such devices being in section in the plane indicated by line?) b in Fig. 1. Fig. 5 is-a View showing in fplan and detachedfrom the pen a feedof surplus n ing device-constructed' in amodiiied form andv embodying my invention, this form of the device being especially .designed for use in connectionwith pen-points of small size. Fig. 6

` `is a transversesection taken through the form blar to Fig, 2. Fig. 11 is an end elevation of.

hthe feeding deviceras shown. in Figs. 9 and 10. Fig.k 12 1s a transverse section taken Figs. 9,10, and 11, the plane of the section lbeing 'along line CZ @Z in Fig. 10.k Fig. 13 is a transverse sectionshowing still another modifiedform o f the. improved feeding device.

As shown in the views, and referring particularlyto Figs. 1,`-2,i 3, and l of the drawlpen, and 2 indicates the screw-plug commonly l employed fonclosi-ng the open end of the same and for 4holding thepen and feeding devices, andl 3l indicates .the `removable cap adapted vto 4.fit upon v'said plugto yguard or shield the penpoint 4L. when -thefdevic'e is not required for usen.l -.indicates the feeding device as a whole, L

-saiddevice being in the form of a cylindrical rod `or ,piece .passed through the plugs-S and having a shoulder 6 at the forward vendof said plug, being provided abovesaid shoulder 6 at its said forward ,end with a projecting tonguel or feeder 7, the upper surface of which is made r convex to conform lto the .perimetral surface through .the feeding-device asv-.illustrated in Y ings, lindicates .the reservoir of a fountainof the body portion 5 and to the underside of '4; the pen-point4,which is fitted in the'screw-plugl .s 2 above said convex surface, with its nibs projecting, as shown in Fig-2, inposition for use IVOO Fig. 1, to a point near but separated from the forward end of the feeder, as indicated at 9, at which point said forward end of the feeder is slightly flattened to permit the inl( to be fed readily to the pen 4. The tongue or feeder 7 at the forward end of the body portion is provided at opposite sides of its central feedgroove 8 with longitudinal slots or channels 10 10, parallel with the feed-groove and extended through said tongue or feeder from its upper to its lower surface, as illustrated in Figs. 3 and 4, and these slots or channels 10 10 form overiiow chambers or receptacles in which is adapted to be received and held any surplusage of ink which may be fed to the pen-point from the groove 8 over and above what is required or desirable for writing, such surplus ink flowing readily th rough the interstices between the pen-point and the convex upper face of the feeder or tongue 7 into the overfiow-chambers, as will be readily understood. In this way it will be seen that the surplus ink over and above what isv required in the use of the pen is carried to the overflow chambers or receptacles at opposite sides of the feed-groove and is prevented from running down and dropping from the nibs of the pen-point, so that the liability of drops of ink falling from the pen and forming blots in the use of the same is altogether avoided and the action of the pen during writing is made uniform and regular.

In the construction shown in Figs. 1 to 4 the grooves or channels 10 10 are closed at their forward ends, as seen at 11 11, by the forward extremity of the tongue or feeder 7, through which said slots or channels are not extended, and are also closed along their outer sides by the lateral portions 12 12 of said tongue or feeder, and said grooves or slots 10 10 are made quite narrow, so as to avoid liability of the ink contained therein dropping from the feeder during the use of the pen; but when the device is used in connection with small pens the closure of the outer sides of the grooves or slots by the lateral portions of the feeder is not essential, since the overhanging sides of the pen-point will rest closely adjacent to the sides of the feeder and will accomplish the same result. Y

. In Figs. and 6 I have shown a form of feeder of this nature, wherein the slots or channels 10a 10a are open along their outer sides, said open outer sides being adapted to be closed, as indicated in Fig. 6, by the over- `hanging sides of the pen-point, whereby the ink contained in the overflow-chambers thus produced will be held and prevented from dropping from the pen during writing.

In Figs. 7 and 8 I have shown another form of the improved feeding device, wherein the grooves or slots 10 10 at opposite sides of the feed-groove are formed between the tongue or feeder 7 and an auxiliary tongue or projection 13 extended from the body portion 5 of the feeding device beneath the tongue or feeder 7, the under side of the feeder being in this case made convex and the upper surface of the auxiliary tongue being concaved to correspond with but spaced from said lower surface of the feeder to produce the overiow-chanibers 10 10 between the opposite sides of the tongue or feeder 7 and the outer edge portions 12 12 of the auxiliary tongue 13. The central portion 14 of the space between the tongue or feeder 7 and auxiliary tongue 13 in this form of the device affords acommunication between the two overiiow chambers or grooves 10 10. In Figs. 9, 10, 11, and 12 I have shown another form of the device, wherein thel auxiliary tongue or projection 13 is made with a convex upper surface, while the under side of the tongue or feeder 7 is concaved to produce the overiiow chambers or grooves 10" 10b, which are thus disposed lengthwise upon the under side of the device, being connected centrally with each other, and the forward end of the auxiliary tongue or projection 13" is curved upward, as seen at 15, and is arranged to engage under the pen-point at a location in advance of the forward end of the feeder 7, being spaced apart therefrom to permit the surplus ink to iow down within the grooves or chambers 10b 10". The bent portion 16, at the forward part of the auxiliary tongue 13, is reduced in thickness to facilitate the downward flow of. the surplus ink. The upwardly-curved portion l5 beneath the pen-point is in position to guide the surplus ink therefrom into the overflow-chambers when too much ink is supplied and at other times guides ink from the overflow-chambers to said pen-point to render the operation of the device in writing regular and uniform.

In Fig. 13 I have shown still another modified form of the device, wherein the under side of the feeder 7is rounded or convex and the auxiliary tongue or projection 13". is made with a flattened upper face, between which Vand said rounded underside of the feeder the slots or channels 10c 10c are present at opposite sides of the feed-groove 8, said grooves or channels 10c being centrally connected by a space 14L in a way similar to that shown in Figs. 7 to 12; but this central space is reduced in thickness, so as to more eifectually hold the ink and prevent blotting.

In each of the several forms of the improved pen herein shown it will be observed that the overiiow grooves or cuts are entirely independent of the feed-gioove, being separated therefrom by surfaces on the feedingtongue along opposite sides of the feed-groove and adapted for contact upon the under surface of a pen-point when the latter is in position in such a way as to etfectually prevent the iiow of ink transversely of the tongue from the feed-groove into the overflow-chainbers until the ink shall' have reached the extremity of the pen-point, at which position IOO IIO

the*` surplus supply of ink is free to 'flow into the overflow-chambers and will be held therein and prevented from dropping in blots from the pen. From the above description it will be seen that the improved pen constructed according to my invention is of lan extremely simple `and inexpensive nature and is especially well adapted for use, since the feeding devices herein shown and described effectually-prevent the dropping of ink from the pen-point, so that blotting is prevented, and the action of the pen is made uniform and regular, any surplus ink supplied through the feed-groove being held within the overiiow-chambers until it is required for use, when it is permitted to Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
