' is fitted into the end of the pen holder, to

close the same and provide a gradual supply of ink to the pen points from the holder, or ink sack therein. i

A primary difiiculty in practically all fountain penshas been to gage properly the feeding capacity of the feed plug to theparticular pen in connection with whichit is used, so that the ink supply to the pen will be sufiicient, but not so great as to cause blotting. Another difiiculty, which has been encountered, more particularly with fountain pens of large size, having relatively great ink capacity and which are filled by the suction action of a rubber ink sack in the holder,

has been to provide a construction which will fill within a reasonable time, say within 10 or 15 seconds, and will not, at the same time, have a tendency to blot, the danger of which, in most constructions, is greatest when the sack is nearly empty.

In forms of feeds most generally employed, one or more feed grooves are usually provided which extend beneath the nibs nearly to the tip of the feed. With these constructions, practically all the ink, which is drawn into the sack when filling, passes thru the aperture in the pen, to which the slit between the nibs extends, into the feed grooves, and, as this aperture is small, in filling an ink sack of large size the time required is ob-- jectionably long. In consequence the average user removes the pen from the ink before the sack is completely filled, so that the benefit of the large ink capacity is not secured.

The objects of my'invention are to prov de an improved form of feed, with which a sufiicient supply of ink to the pen points will be provided and at the same time blotting and flooding at any time, and particularly when the ink sack is nearly empt w1ll be avoided, and with which the sac may berapidly filled, so that-the full benefit of a large ink sack may be secured without the attendant disadvantages above referred to.

I accomplish these objects by providing the feed with an elongated face which closely engages the middle portion of the under side of the pen from points adjacent the ends of the nibs to points beyond the. pen

aperture at both sides thereof, so that all the ink is fed to the nibs over said face, and by providingink feeding grooves and recesses which extendto the inner end of, and at each side of said face, and which open to the under side of the feed adj acent its tip and permit free inflow of ink when filling.

For amore detailed description of the invention, reference is made to the accompanying drawings, in connection with the following spec1fications.

In the drawings:

Fig. 1 is a longitudinal central sectional view of the pen section end portion of a fountain pen embodying my invention, the same being. shown on an enlarged scale.

Fig. 2 is' a similar view, in which the feed is shown in elevation.

Fig. 3 is a plan view of the feed, showing the position of the pen thereon in dotted thereof, the mouth of the sack being connected to the inner end of said section. A feed 4, having its inner end portion formed cylindrically, istightly fitted in the bore of the section 3, the outer end of the bore being sufliciently enlarged'to ermit the pen 5 to be set ti htly therein on t e upper side of the feed. T e penis of the usual type, having the usual having a bore extending fromend to end slit between the nibs which terminate in an aperture 6, which isgenerally known as the heart of the pen.

' The feed in general sha and outline, is

similar to those ordinari y emplo ed, but

differs therefrom in certain particu ars now to be described.

A feed groove 7 is provided in the middle of the top side of the feed, in the bottom of which two parallel ribs 8, are referably formed,'to provide additional capi a feeding surface. The feed roove 7 extent s from the inner end of the feed to the inner end of an elongated unrecessed face 10, which is formed on the middle portion of the top side of the feed and extends from its outer end, or tip, to a point at a short distance beyond the pen aperture 6 and is of substantially greater width than the width of said aperture, said face being closely fitted against the corresponding portion of the under side of the pen, so that it completely closes the pen aperture and engages the pen at each side ofthe slitbetween the nibs.

Pockets 12 are formed in the feed at each each side of face 10, said extensions, 0 en-' ing at their outer ends, to the inner en s of pockets 12, respectively, and at their inner ends-to the groove 7, which terminates at the inner end of face 1O,- said pockets 12 and feed grooveextensims thus forming the side marginsof 'face 10. A- series of. transverse thereof by notches 14 are formed in each side of the-feed, in a manner commonly employed, the two notches at each side nearest the t1 end opening to pockets 12 and the others ing separate from the groove 7 by a surface tpprt on er side of the feed which bears against the un ofthepen..

With the above described construction, when the pen is in use, ink is supplied to the points of the nibs by capillary attraction over the face 10, which may be termed a feeding face, ink being supplied to the inner end thereof by the groove 7, and to the sides the groove extension.9 andthe kets 12, all of which become filled with nk, and in which the ink is retained by capill'ary attraction. With this construction, therefore, none of'the ink feeding passages, or ink retaining pockets, open directly to the pen-aperture 6, or tothe slit between its nibs, but they supply the ink to both the side and the inner end edges of the 10, an that an ample ink supply is provided to constructions ordinarily emp said face when the pen is used. As all the mk which is supplied to the nibs must be fed over the face 10, the supply of an excesslve amount of inkto the tips of the nibs 1s prevented, and the danger of flooding is avoided.

The pockets 12 virtually form enlarged o' uter end rtions of the feed groove extensions 9 an act as small reservoirs, by providng an ample supply of ink adjacent the writing point, so that ink will be supplied to the o nts over the face 10 immediately on their mg brought into contact with the paper and a uniform flow of ink, thereto will be assured. The construction of the pockets 12 is, however, such that the ink which is fed thereto will not escape to the under side of the feed, but will ordinarily be retained therein bycapillary attraction. p

In filling the ink sack by suction in the usual manner, no ink will pass thru the pen aperture into the feed oove 7, but, as this groove is directly connected, through the groove extensions 9, with the pockets 12, to which the outermost'side notches 14 open directly, the ink will be free to flow from the well in which the penis immersed, through the outer notches 14 and kets 12, thru-the extensions 9 and oove into the ink sack, so that the sack wi 1 be quickly filled.

With the above described construction, as

all the ink is supplied to the writing point of the pen over a capillary feedin surface, which bears against the under si e of the pen beneath the en aperture and slit, excessive feeding or ooding is prevented, while, at the same time, an ample supply of ink is provided to said surface by supplying ink thereto at its inner end and at both side edges, and this is accom lished not only without reducing the rapidity with which the sack will draw up the ink and become filled, but a construction is provided which will permit the sack to become filled more rapidly than'would be the case if the feed grooves opened directly to the pen aperture, as with oyed. I claim:
