'FOUNTAIN-PEN.

SPECIFICATION forming-part of Letters Patent No. 758,934, dated May 3, 1904.

Application led January 15, 1903. Renewed March 23, 1904. Serial No. 199,627. (No model.)

To rtZ Mmm t ntfty concern.

Be it known that I, JOHN SorER PURDY, of Brooklyn, in the county of Kings, and in the State of New York, have invented a certain new and useful Improvement in Fountain- Pens; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying' drawings, in which- Figure l is a longitudinal sectional view of a penpembodying Vmy invention. Fig. 2 is a view showing in elevation the pen illustrated in Fig. 1. Fig. 3 is a transverse sectional view through the body of the pen looking' toward the pen-point. Fig. 4 is a longitudinal sectional view through the point-section and parts attached thereto, and Fig. 5 is a longitudinal sectional view of ,the air-tube and cleaner.

The object of my invention has been to provide a fountain-pen which shall have, among others, the following advantages: of insuring a steady and uniform flow of ink, of being capable of using a soft and elastic pen-point, of preventing' the formation of air-bubbles, of insuring the proper admission of air into the pen-body, and of having its parts readily separated for the purpose of cleaning; and to such ends my invention consists in the fountain-pen hereinafter specified.

In carrying my invention into practice I' provide a pen-body A, into which a ring B is screwed, the engagement being preferably by a right-hand thread. The ring B is provided with an internal thread b, which is preferably of an opposite character from that of the thread by which the ring engages the body and in the instance chosen for illustration is a left-hand thread. The thread b preferably terminates at the base of a shoulder b, and a point-section C is screwed into the ring B by engagement withthe thread and preferably until the rear o1' upper end of the point-section comes in contact with the shoulder L'. The point-section is provided with a pen-slit c for the reception of the pen-point D. An ink-passage c is formed in the lower portion of the point-section and extends from a flaring' opening' cz 1n its rear or upper end forward and opens beneath the pen-point.

Above the pen a passage 03 isformed through the pen-section, and a tube E, preferably of metal, is inserted in the passage c". The said tube has its forward end preferably flattened and bent down toward and close to the upper surface of the pen-point, where it is provided with a slit e for the admission of air. A rod F is mounted in the tube E and at its lower or forward end is bent upward and extends through a slot e in the tube E, the upwardlybent end of the said rod serving as a handle f, by which the rod can be moved in the tube. The rear end of the said rod is provided with an eye j, which eye is engaged by an eye g, formed upon a rod Gr, the latter being' preferably formed of wire and of sinuous shape and extending' through the passage 0; The length of the rod F is preferably such thatits handlef' can reach to the forward or lower end of the slot e in the tube E, so that the eye'upon the upper or rear end of the rod will not contact with the adjacent end of the tube E and prevent movement of the rod until the said rod has reached the forward end of the slot e. The rods F and G constitute cleaners. A sleeve H is secured, preferably, upon the pen-section C, as by a threaded engagement, and such sleeve is provided with a reduced portion /L for the reception of the cap I. lf desired, the ring B can at its forward or lower end be provided with a flaring opening for the reception of a conical shoulder 0*, formed upon the pen-section, and the sleeve can be screwed against said shoulder. The rear or upper end of the body is preferablyprovided with a central socket a, in which is held, preferably by friction, a tube K, the tube being readily removable from its socket for the purpose of cleaning. The tube extends forward toward the forward end of the body, and at such end theY tube is open. The tube is also preferably provided with a metal sleeve for protection and with openings f through the tube and the sleeve. A rod L is loosely mounted in the tube K and at its forward or lower end is provided with an enlargement or shoulder which, as illustrated, consists of cross-arms I, that prevent the said rod from entering the said tube beyond a given distance. Ifv desired, the said cross-arms can be omitted.

IOO

In the operation of my fountain-pen the holder is filled with ink and the pen operated by the mere act of Writing. The air Will pass up the tube E and into Vthe body of the holder and Will cause a free flow of ink down the passage beneath the pen-point. The act of tipping the pen into Writing position will cause the rod L to fall and break any bubbles which may have formed in the lower end of the chamber in they pen. The presence of the Wire G in the passage c prevents a too ready flow of ink. Should the How of ink be obstructed either by the clogging of the tube E or the passage c', the end of the rod F is engaged in any convenient manner-such, for instance, as by a hole z' in the cap I-When the rod F and the Wire G are caused to' reciprocate in their respective tubes by moving the handle f back and forth in the slot e. By the movement of the said handle the pen is conveniently and immediately relieved from any clogging and a proper flow of ink is immediately produced. Should any ink travel down the tube E, it is conducted by such tube to a point above the pen-point, Where it Hows upon the pen-point and passes Without difficulty to the paper Which is being Written upon. The eye f', at the rear end of the rod F, forming, in effect, a shoulder, by coming in contact With the pen-section C prevents any strain being communicated to the tube E, such as would cause said tube to be drawn out of its place in the pen-section. Since the air is perfectly supplied to the pen by means of the tube E, the iow of ink to the pen-point does not depend upon the point being raised from the passage c' beneath it, and I am consequently enabled to use a pen having elastic nibs and one Whicliwrites more easily than the pens required by all-the fountain-pens of which I am aware. The tube K being merely forced into its socket can, like'all the other parts of my pen, be readily removed for cleaning.

It is obvious that various changes can be made in the above-illustrated construction Which Will be Within the scope of my invention.

Having thus described my invention, what I claim isl. In a fountain-pen, the combination of a pen-body, a tube extending longitudinally of.

the chamber in said pen-body and being readily removable therefrom, and a rod loosely mounted in said tube and adapted to fall back and forth therein.

2. In a fountain-pen, the combination of a pen-body, such body having a tapering socket a tube'eXtending longitudinally of the chamber in such body, said tube being engaged solely by friction with the said tapering socket in said body, and a rod loosely mounted in said tube.

3. In a fountain-pen, the combination with a pen-body, a tube extendinglongitudinally of the chamber in said body, and a rod loosely mounted in said tube, said rod being adapted to fall from said tube, and to break air-bubbles formed in said chamber.

4. In a fountain-pen, the combination of a pen-body, a tube extending longitudinally of the chamber in said body, and a rod loosely mounted in said tube, said rod having a shoulder to prevent saidrod from completely entering said tube.

5. In a fountain-pen, the combination of a pen -section having an ink-passage beneath the pen-point, and having an air-passage above the pen-point, said airfpassage having an opening upon its sideoppositeto said penpoint.

6. In a fountain-pen, the combination of a pen-section having an ink-passage beneath the pen-point, and a; tube inserted in said pensection above the pen-point, said tube having an air-receiving opening upon its side opposite to said pen-point. p l

7. In a fountain-pen, the combination of a pen-section having an ink-passage beneath the pen-point, and a tube inserted in said pen-section above the pen-point, said tube having an air-receiving opening upon its side opposite to said pen-point, and having an opening adjacent to the upper surface of the pen-point.

8. In a fountain-pen, the combination of a pen-section having an air-admitting passage therein, a rod mounted in said passage yand extending outside the pen-holder, so as to be capable of operation while the parts of the penholder are assembled.

9. In a fountain-pen, the combination of a pen-section having an air-admitting tube therein, and a rod mounted in said tube, and having a handle extending through a slot in said tube.

10. In a fountain-pen, the combination of a pen-section, an air-admitting tube mounted in said section, a rod extending through said tube. and having a handle extending through a slot in said tube, said rod havinga shoulder adapted to engage with the pen-section to prevent the Withdrawal of said tube.

ICO

1l. In a fountain-pen, the combination of a I pen-section having passages above and beneath the pen, cleaners mounted in said passages and connected together, one of said cleaners having means for engagement that is accessible when the parts of the pen are assembled.

In testimony that I claim the foregoing I have hereunto set my hand.
