AZEL S. IiYMAN AND MATTHIAS W. BALDlVIN, OF PHILADELPHIA, PENN- SYLVANIA.
IMPROVEMENT IN FOUNTAIN-PEN HOLDERS AND NIKBS.
Specification forming part of Letters Patent No. 5,789, dated September 194, 1848.
To all whom it may concern:
Be it known that we, AZEL S. LYMAN and MATTHIAS W.' BALDWIN, of Philadelphia, inl the county of Philadelphia and Stateof Pennsylvania, have invented nettT and useful Im provements in Fountain-Pen Holders and Nibs; and we do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, Inodifying, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Fign re lis arepresentation of our improved pen-nib and fountain-pen holder; Fig. 2, a longitudinal section thereof; and Fig. 3, a crosssection of the same, taken at the line A a of Fig. l. Fig. 4 is a representation of a difterent mode of applying the principle of our improvements; Fig. 5, a longitudinal section, and Fig. 6 a cross-section, of the same, taken at the line B b of Fig. 5; and Fig. 7is a front view of the pen-nib, and Fig. 8 an edge View of the same, and Fig. 9 arepresentation of an elastic pump for supplying the fountain with ink.
The same letters indicate like parts in all the figures.
The irst part of our invention relates to the fountain-holder for supplying ink to the nib; and the nature of this part of our invention consists in supplying the ink to the pen from a bag or chamber, the whole or part of which is to be made of india-rubber or other elastic or yielding substance, air-tight except asmall hole for the supply of ink to the nib and placed within the handle or in a recess there in, so that the writerby making pressure with the finger or thumb will compress the bag or chamber and force out the required supply of The second part of our invention relates to the method of preventing the escape of ink when the pen is not in use, and consists in using a spring-plug attached to the inside of the cap or cover of the pen, so that when this is slipped on over the pen the said plug will enter the aperture through which the ink is Supplied from the fountain to the nib,thetension of the spring retaining it there.
The third part of our invention relates to the method of preventing the elastic bag or ink-chamber from collapsing and adhering,
which is effected by the use of aplate of metal or other substance placed Within the bag, which prevents the inside surfaces'of the india-rubber from being pressed together and adhering.
The fourth part of our invention relates to the method of making pen-nibs, and consists in making the point of the nib of metal put into nibs made of quill, whereby the durability of the metal for the point is combined with the elasticity of thefquill-nib.
In the accompanying drawings, a represents the handle of the pen-holder, which isa hollow metal cylinder with the lower end provided With a nib b in any manner desired. The lower ende of the cylinder is closed, except a small aperture d, through which the ink flows from the fountain or reservoir in the handle to supply the nib. Atethe met-al of the cylinder is bent in to form a recess to receive a bag or chamber made of india-rub- ,ber or any of Vthe compounds thereof or of other elastic substance which will retain inkf and the open end of this bag is properly secured to a neck or tube f, which communicates and extends up near to the top of the hollow handle. In this way when the hollow handle or fountain is filled with ink and the bag with air it will be perceived that when pressure is made either with the thumb or finger on the elastic bag the ink will be forced out by the elasticity of the air through hole d to supply the nib, thus enabling the writer, without the necessity of dipping, to keep his pen constantly supplied with ink; but the moment that the pressure is removed from the bag it expands by its elasticity and prevents the ink from flowing. When the pen is not in'use, a cap-tube g, closed at one end, is slipped over the pen and the bag to prevent any accidental pressure from forcing out the ink. This cap-tube is represented by red lines in Fig. 2, and to the closed end of this cap-tube is attached a rod h, on which slides another rod t', a portion of which is hollow to slide on the rod h, and the point of the rod is adapted to t the hole d, through which the ink flows from the fountain to supcaping, and hence the pen may be carried with safety in the pocket.
Instead of using` the elastic bag as an airchamber, it may be 'used as an ink-receiver, in which case the neck or tube f need not be extended up into the hollow handle, but simply communicate therewith, so that when ink is introduced into the hollow handle or fountain it also enters and fills the elastic bag.
The ink is supplied to the fountain by an india-rubber pu nlp. (Shown separately in Fi g. D.) It consists simply of an india-rubber bulb attached to one end of a tube, the other being adapted to fit a hole in the upper end of the handle or fountain. The bulb being supplied with ink, the tube is inserted in the fountain, and by making pressure on the bulb the ink is forced into the fountain and elastic bag, when desired. Then the pump is removed, a ground-plug K is inserted in the hole to pre-l vent the escape of ink. The fountain may,` l1owever,be supplied Without a pump by compressing the elastic bag to force out the air and then permitting' it to expand while the hole cl is dipped in ink.
In Fig. 5 it Will be seen that a strip of metal p is attached to the neck fand extends up into the bag. This prevents the india-rubber bag from being collapsed and the inside sui'- faces from adhering together.
Instead of placing the elastic bag in a recess made at the side of the handle, it may be let into the hollow cylindrical handle, as represented in Figs. 4, 5, and 6, the neck to which it is attached being reversed in this instance, and to make pressure on the bag when thus applied a portion of the tubular handle is slit longitudinally, as shown at u, to constitute a spring which rests against the elastic bag, before described, so that when this spring is pressed in by the finger or thumb it compresses the elastic bag and forces out the ink; or instead of this modification a piece of india-rubber or other elastic or yielding substance may be put over the recess in the side of the handle or over a hole in the handle. In short this may be variously modified so :use
long as the whole or a portion of the reservoir or fountain is made of an elastic or pliant substance, which will readily yield to the pressure of the thumb or finger of the Writer, so that the supply of ink to the nib may be kept up While writing.
The nib m of the pen is composed of one piece of quill with a slit, or two pieces, prop- .erly secu red in a holder in any desired manner, and the points of the two nibs are each plated with metal n n in the following manner: A thin piece of sheet metal (say gold or silver) is bent, as shown in the separate figure 0, slipped onto or over the nib and then pressed together and riveted thereto and properlypointed.` lf desired to make the attachment more permanent, any suitable mastic or cement, such as shellac mastic, may be used. In this Way the durability of the metal point is combined with the elasticity of the quill. It will be obvious that instead of lining both surfaces of the quill, the under surface alone may be lined by using a strong mastic which Will act on the metal and quill; but the mode described above will be found to be the best; and it will also be seen that the nibs thus formed may be used in connection with penholders of any suitable construction irrespective of the improvement-s in the fountain and holder described above.
What we claim as our invention, and desire to secure by Letters Patent, is-
l. The method of supplying ink to pens from a reservoir in the handle by means of a bag or chamber, the Whole or part of which is made of gum elastic or other yielding sub` stance, substantially as herein described, whereby the writer can by the pressure of the finger or thumb supply the nib with ink While writing, and thus avoid the necessity of dipping the pen.
2. The method, substantially as described, of preventing the escape of ink from the fountain by combining the spring-plug attached to the cap, as described. i
3. ll'laking pens by coating or plating quillnibs with metal, substantially as described.
