11 Claims. 1

The present invention relates to dip pens-and has more particular application to such asare "capable of Writing a page or-more on a single dip.

Where a pen nib is made with an auxiliary nib reservoir, its manufacture inherently adds to same time causing deviations from 'its predetermined flexibility and other writingcharacteristics.

Where on the other hand, the auxiliary ink capacity is incorporated in the holder, the-latter becomes expensive in construction in that it partakes of many of the complications ofa fountain pen-and greater difiiculty is entailed in'the regulation and control of ink inthe writing operation.

It'is among the objects of the invention'to-provide a dip pen which is devoid of an ink vessel, either on the nib or in the holder, but which yet holds'a volume of ink onasingle-din-suflicient for the Writing of a page or more, which-:it-releases at desired rate in writing.

Among other objects are to provide a dip-pen of the above character, in'Which the holder-may be fashioned of a single unitary integral piece without auxiliary nib holding clamps, -the-construction of which involves no added-weight-or loss of balance or deviation from' the weight ef stroke made by a nib of given hardness or softness,'and from which the wet nib may be 'removed by the bare hand without soiling-the fingers.

Fig. 4 is a transverse sectional view on an 2 inlar'ged scale taken on lined- 4 of Fig. 1,' and l Fig. 5'iisafpersp'ective' view of the pen nib.

Referring now to the drawings, the pen holder in maybe asingle unitary piece of appropriate :5 material, such as plastic, metal, impregnated woodyor the like. It is illustratively shown with a flattened letter opening "upper end I I and a pe- -ripherallyreduced'grip portion l2 near its writ- -ing end, Whic'h'latter end is tapered 'laterallyias IO-besFshOWn-in'Fig. 3' to a narrow rounded end 13. shown; the pen holder hasa longitudinal slot or bifurcation'pre'ferablyaplane slot'l l' across the ntire widtho'f-the tapered writing end thereof. That bifurcation is desirably of length in the r order" of T /8 inch "and" aifordsa gap of thickness in the-order-of 1020 inch. 'In' a preferred'em- *bodiment, thewriting end W of the pen is conical as shown, =that-'is, iit is uniformly tapered'in every'longitudinalplane'as shown. If desired, '20 "the otherwise conical conformation could be fiattened; cutaway orntherwise formed at opposite sides of the bifurcation, without interference with the functionalrelationship 'of this bifurca- -'-tion oftheholder to the penni'b,"to be described ---loelow.

'T-he pennib best shown in Fig. 5 -is-preferably -a=unitary stamping-having a-fiat body l5, gen- --.erally triangular in contour and of length pref erably slightly greater than that of the bifurca- -tion 1in the holder, so "that nearly the entire length of said nib: maybe I accommodated within the bifurcationfor its narrow Wn'ting-end'l5' only, which is'desirably equipped with'an iridium point i6=to protru'debeyond the pen holder as -Desirably the pen nib is so conformed that it --may readilybe introduced into the holder, with- "Out --the"possibi1ity of entering "into skew or olfcenter relation, -that it will-inherently be fric- 40 --tional-ly held in pla-cein the holder, and thatit will afford an open capillaryspace with-respect to the bifurcation for holding a volume of ink sufficient fer sustained writingofea page or more in=one-dip. To'this-end,the pen nibis formed with symmetricaltguide conformations relative-t0 the holder, *which conformations also exert-friction against the holderto assist iii-maintaining the nib in; place.

-In thespecific-embodiment shown, thep'en' nib is provided with one or more pairs of clamp jaws integral therewith, desirably two pairs, one :pair .l-l being near the-root or *baseend of the-nib, and the second pair lS'at a 'substantial'distance therefromas-shown,g-and-slightly beyond the lon- -gitudina1s1it +9-at the writing end '-of the-.mb'.

bifurcation will inherently embrace and clasp;

the writing end of the holder adjacent the lateral edges of the bifurcation, with the root end 2| of the nib spaced slightly from the end 20 of the bifurcation. The jaws are preferably slightly curved inward and toward grip l2 and are conformed for snug accommodation of their inner faces against the face of the holder, as shown. The pen nib thus becomes automatically centered in the bifurcation and the jaw pairs I1 and IS in frictionally grasping the holder help to retain the nib in place.

While the jaws I l and I8 could be so conformed as in themselves to provide substantial friction, it is preferred to provide one or more embossments 22, desirably near the root end of the nib which afford enhanced frictional hold with respect to the wall of the bifurcation I l in the holder, thereby to avoid any inadvertent or undesired displacement of the pen nib during use.

Preferably, the thickness of the pen nib is but half or less than half the thickness of the bifurcation l4, so that adequate capillary space is left between the walls of the bifurcation and the faces of the pen nib. Further to enhance the capillary ink space, the pen nib may be laterally cut away as at 23 between the pairs of clamp jaws I! and I 8.

In a preferred embodiment shown, substantially the entire body of the pen nib is retained within the pen holder and only the short pointed end l5, preferably only a length of between and inch protruding. Accordingly the writing point receives adequate face support in use.

On a single dip, desirably to a level near the upper pair of clamps ll, ink will be retained not only in the flat space between the bifurcation walls [4 and the faces of the nib, but also in the segment shaped openings 23 between the faces of the nib. All of these spaces are capillary in character, but conjointly they retain suificient ink to permit writing of a page or more on a single clip. The capillary space effectively holds the ink against overfeed or blotting, yet readily releases the ink in the Writing operation, at that rate appropriate to the hardness of the pen nib.

The pen nib even when wet with ink may be withdrawn without soiling the fingers by pushing the finger nail against the extreme edge of a clamp jaw I! to loosen it and by then grasping said dry outer clamp jaws H for removal of the nib.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
