FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 495,238, dated April 11, 1893.

Application filed February 25, 1893. Serial No. 463,718. (No model.)

To all whom it may concern.-

Be it known that I, LUOIEN B. WOOLFOLK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fountain-Pens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the. accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Thisinvention belongs to that class of fountain pens in which the heel of the pen is held in a tubular point section joined to the barrel by a screw joint, the barrel and the point section constituting the ink-holder. It is my aim to make a fountain pen simple in construction and cheaply made, which will not leak. or skip, may be easily cleaned, and not liable to get out of order. This is accomplished by the construction hereinafter set forth in this specification and represented in the accompanying drawings.

The drawings are on an enlarged scale the better to represent my invention.

Similar parts are designated by similar letters.

Fig.18 is a cross section of the same through the line 6, 6, of Fig. 17,1ooking, from the point of the pen. Fig. 19 is a cross section of the same through the line 7, 7, of Fig. 17, looking toward the point of the pen. Fig. 20 is a rear elevation of the point section. Fig. 21 is a plan of the back-stay and feed-tongue seen from beneath. Fig. 22 is a rear elevation of the back-stay and feedtongue. Fig. 23 is a perspective view of the pen.

Referring to Figs. 1 to 13 inclusive, I will describe the preferred form of my invention. In this construction the barrel A is closed at the upper end by the plug B, and it has the lower end thereof countersunk. The tubular point section 0 is provided with an enlarged screw on the upperend thereof which fits into the countersunk portion of the barreYA, forming the screw joint 0. Thescrew of the point-section is enlarged to allow the longitudinal groove hereinafter mentioned, cut in the bore of the point section,to be cut deeper into the wall of the bore thereof. The point section is provided with a cap-flange, on which fits the ordinary protecting cap D, which also fits upon the upper end of the barrel. The cap-flange is enlarged, for purposes hereinafter set forth, to such an extent thatthe protecting cap which fits on it has a greater peripheral diameter than the barrel A. The point section carries the pen E, which will be hereinafter more particularly described. In the upper end of the point section, back of the pen, is cut the air passage F, extending from the upper end of the point section down- 5 Ward Within the screw joint 0. The lower end of the point section is reamed out within the cap-flange to provide an antechamber G back of the pen, and an enlarged ink cup H below the pen. The upper end of the reamto ing is designated the reamed shoulder g.

The space in the bore of the point section below the pen is designated the sub-chamber I. In the bottom side of the sub-chamber I is a sub-groove K outin the wall of the bore of the point section. The sub-groove K may be rounded, or square, or of other suitable form.

The pen E is provided with an ink aperture e in the heel thereof. The pen is preferably provided with ashank in the heel thereof and shoulders below the shank; though it may be made of any usual form. These shoulders of the pen abut against the reamed shoulder g at the upper end of the reaming, and limit the entrance'of the pen into the point section. The sides of the'pen shank rest against the'bore of the point section at the lower end of the bore, but gradually recede from the bore toward the upper end of the shank. The sides of the shank rest against the bore below the center of the bore, and hence the pen may be held firmly in position by pressure upon the back thereof. The back-stay L holds the pen firmly in position by pressing firmly upon the back thereof. The wings of the pen preferably touch the reamed out portion of the point section.

at the lower end thereof.

The back-stay Lis preferably formed of the half of a tube, in which the tubular cavity forms a longitudinal groove in thebottom side thereof back of the pen; though it may be formed of a solid piece if preferred, and the groove may be cut therein in any suitable manner. The back-slay preferably extends from the upper end of the point section down to the reamed shoulder g, at the upper end of the reamingin the lower end of the point section; though it may extend above the upper end of the point section into the barrel, if preferred. At the reamed shoulder g the feedtongue M is joined integrally with the backstay, said feed-tongue being formed by cutting away the lower end of the back-stay. The feed-tongue, as originally formed, joins the back-stay back of the longitudinal groove in the bottomside thereof, as represented in Fig. 8; but it is bent down so as to fit upon the back of the pen, as is represented in Figs. 1 and 7, and extends adjacent thereto for the purpose of conveying ink for writing. The feed-tongue has upon its upper end projecting shoulders, which abut against the reamed shoulder g, and thus limit the entrance of the back-stay into the bore of the point section. 65 The back-stay is preferably provided with a broad slot N therein, extending from near the upper end thereof down to near the point of junction with the feed-tongue; thus leaving the upper end of the back-stay solid, and providing at the lower end of the back-stay a diaphragm O which is not out through by the broad slot N. A narrow slot P cuts through the diaphragm O, and extends down into the feed-tongue M. The top part of the narrow slot P is designated the air inlet R. The bottom of the narrow slot P together with the longitudinal groove in the bottom side of the back-stay forms the ink duct S. The port-ion of the narrow slot extending into the feedtongue is designated the slot 19.

The feed-rod T is held in the sub-chamber I, the bottom side thereof fitting in the subgroove K which is provided specially for the purpose of receiving the feed-rod. The feedrod T is provided with a bottom feed-tongue U, integral with the top side of the lower end thereof, extending beneath the pen adjacent thereto for carrying ink for writing; and it is also provided With a finger V integral with the bottom side of thelower end thereof. The

finger V is separated from the feed-tongue U by the separating slot W. The finger V extends down into the enlarged ink cup H, and, together with the bottom feed-tongue U, partially fills it up, causing it to hold ink by capillary attraction. The separating slot WV extends up into the sub-chamber beneath the shank of the pen, thereby lengthening the bottom feed-tongue and greatly increasingits efficiency.

In the feed-rod is the groove X constituting an ink passage communicating between the ink-holder and the separating slot W. On each side of the feed-rod T in the sub-chamber l are the ink Ways Y, Y, through which vink flows to supply the feed-tongue U, and

out gushes fiow to the ink cupI-I. In this construction ink passes to the pen through two lines of fl'ow:(first) back of the pen, through the broad slot N, the ink duct S, and on between the feed-tongue M and the pen,

and (second) ink also passes to the pen between the bottom; feed-tongue U and the pen.

Ink passes to thebottom feed-tongue (a) from back of the pen, through the ink aperture e in the pen; (1)) through the ink ways Y, Y; and (a) through the ink passageXto the separating slot W, whence it feeds around the bottom feed-tongue and passes to the point of the pen. Ink feeds to the enlarged ink cup I-I:(first) through the ink ways Y, Y; (second) through the ink passage X and the separating slot W; (third) overflows of ink pass into the antechamber back of the pen, and from thence feed around the pen by capillary attraction and gravity into the ink cup H. Ink is fed from the ink cup H to the point of the pen by the bottom feed-tongue U. Air passes through the antechamber G to the air inlet R, and from thence through the broad slot N up to the air passage F grooved in the top side of the bore of the point section at the upper end thereof, and through the air passage F into the ink-holder.

together, thereby partially closing the slot and checking the passage of ink and air, and also preventing the back-stay from fitting firmly all along the back side of the heel of the pen, thus preventing the pen from being held firmly by the back-stay. Both these defects are remedied by leaving the upper end of the back-stay solid. The back-stay fits firmly along on the back of the heel of the pen and holds it solid in the point section;

and the slot is always open for the passage of ink and air.

Anotherimportant feature of my construction is providing the air passage F. By making the upper end of the back-stay solid the passageof air is interrupted at the upper end of the slot N. I found in practice that the air would not readily descend to pass beneath the end of the back stay, but would form a large bubble at the upper end of the slot N that would stop the passage of both air and ink. To remedy this, I provide the air passage F in the top wall of the bore of the point section, extending from the upper end of the point section far enough down to communicate with the slot N and to allow the air to pass freely.

Another feature of my construction is providing the sub-groove K in the bottom side of the sub-camber I. The sub-groove K serves two important purposes:(first) when the feed-rod T is held in the sub-chamber I between the bottom side of the pen and the bottom wall of the sub-chamber, it is not held fixedly therein, but the feed-tongue U is suffered to move from side to side upon the pen. The sub-groove K holds the feed-rod firmly in a straight position, so that the feed-tongue is held fixedly beneath the center of the pen. This is a very important advantage; but the second is even more so, which is this(sec- 0nd) when the round feed-rod Tis held in the sub-chamber between the bottom side of the pen and bottom wall of the sub-chamber, it is necessarily so small that it leaves the ink ways Y, Y, on each side of it so large as to cause the pen to leak, for-the sub-chamberi is much narrower from the top to the bottom side thereof than from side to side. By providing the sub-groove K, the feed-rod fitting therein may be made so much larger as to make the ink Ways Y, Y, small enough to prevent leaking. .By regulating the depth of the sub-groove, the size of the feed-rod may be so adjusted as to make the ink ways Y, Y, just so large as to pass ink freely without passing it so freely as to cause the pen to leak.

Another feature of my construction is countersinking the lower end of the barrel A, so as to enlarge the screw of the point section fitting therein, and thus allow the air passage F and the sub-groove K to be cut deep enough in the walls of the bore of the point section to perform their functions properly. Those grooves must not be deep enough to cut the screw joints 0; and if the screw were not enlarged by countersinking the lower end of the barrel for its reception, the air passage F. would be too shallow to allow the free passage of air; and the sub-groove K would be too shallow to hold the feed-rod firmly and straight, and to allow the feed-rod to be made large enough to close up the ink ways Y, Y, sufficiently to prevent the fountain penfrom leaking. Oountersinking the lower end of the barrel allows both those grooves to be made deep enough to perform theirfunetions sufficiently. 4

Another feature of my construction is holding the pen in position by the pressure of the back-stay L, the shank of the pen bearing upon the bore of the point section below the center of the bore, and the shank touching the bore only at the lower part of the shank, and the lower end of the bore. I find it is exceedingly difficult to have the shank touch the bore of the point section along the whole length of the shank. It is much more easily adjusted and the back 7 stay holds the pen quite as firmly when the shankbears upon the bore only at the lower part-of the shank, and the lower end of the bore. 7

Another feature of my construction is providing in the back-stay the broad slot N, the

diaphragm O, and thenarrow slot P containingthe air inlet R and the ink duct S. The broad slot N gives a full flow of ink down to the lower end thereof: The diaphragm 0 prevents the ink from running out in a stream at the lower end of theback-stay, as it would do if the broad slot N cut through the lower end of the same; and the narrow slot P through the diaphragmregulates the outflow of ink through the ink duct S and theinfloW. of] air through the air inlet R. The broad slot N secures a free flow of ink and air. The short narrow slot P secures a regular and regulated flow. Without the broad slot N the flow of ink and air would be .meager, irregular and liable to interruption; while the narrow slot P is necessary to prevent leaking, and to regulate the flow.

Another feature of my constructionis forming theback-stay L of part of a tube, so as to form the longitudinal groove in the under side thereof. This is especially important in connection with the broad slot N. Where there is no groove in the under side of the backstay, the back-stay rests upon the center of the pen only, and the broad slot Ncuts away the bearing of the back-stay upon the pen every Where except at the lower end thereof. But the broad slot N does not extend out to the sides of the groove in the underside of the back-stay, and these sides of the groove bear IIO evenlyupon the back of the pen along the whole length of the heel of the pen, holding it evenly and firmly.

Another feature of my construction is providing the feed-tongue M integral with the back-stay L. The feed-tongue M and the bot tom feed-tongue-U below the pen mutually aid each other in securing an evenconstant flow of .ink to the point of the pen; for each leads ink to the point of the pen, and each gathers uponits own side of the pen the ink brought by the feed-tongue on the opposite side thereof. Thus both sides of the pen are,

.cup was too smallto prevent leaking. 1-

found that leakingcould be prevented only by shortening the point section so as to' ream out the ink cup within the'capflange,

and enlarging the cap-flange.

Another exceedingly important feature of my construction is formingthe-antechamber entire, by reaming out the lower end of the pointsection. If therewere no reaming the shoulders of the pen would abut against the,

.lower'end of the point section. As it is, the shoulders of the pen abut against thereamed shoulder g at the upper end of the reaming. Ifbthe reaming only slightlyenlarged the diameter of the bore of the point section, ink

would stand between the feed-tongue M and the wall of thepoint section, held by capillary attraction, and wouldwholly interrupt the entrance :of air through the ante-chamber G. In order to the successful working of my fountain pen, the antechamber G must'be large .enough not to hold ink firmly by capillary attraction; and it can be made of an.

adequate size only by reaming it out within the cap-flange.

-A most important feature of my construction is enlarging the cap-flange, making it so large in' diameter that the protecting cap fitting thereon has a greater peripheral diameterthan the barrel A. This enlargement gives room Within the cap-fiange for reaming out the ink cup and the antechamberlarge'enough for the adequate performance of their func tions.

Another feature of my construction is having the wings of the pen touch the reamed out portion of the point section, thereby strengthening the bearing of the pen in the point section.

Modifications may be made in point of structural detail without departing from the general principle of my invention.

The modification represented in Figs. 14 and 15 only differs from the preferred form in one particular:-There is no feed-tongue M back of the pen integral with the back-stay L; but the back-stay L extends down almost to the slit in the pen, and is cut away on the top side thereof below the reamed shoulder g, to allow air to pass through the antechamber G to the air inlet R. The slot 19 is cut into the back-stay below the .reamed shoulder-g. In all other respects this modification is similar .to the preferred form. This modification will work very well, though notso well as the preferred form. Ink is carried to the pen by the bottom feed-tongue U; air enters the barrel as .in the preferred form; and overflows of ink pass to the ink cup Has in the preferred form.

In Fig. 16 a modification of the back-stay L and feed-tongue M is represented, which differs in one particular from the preferred form :-The; modification has no broad slot N;

but the narrow'slot P containing the airinlet R, the ink duct S and the slot 10 in=the feed-tongue M, is continued almost to the upper end of the back-stay, where .it communicates withthe air passage F. In all other particulars this modification'is the same as thepreferred form. This modification of the back-stay is more readilymade thanthe preferred-form thereof, but it will not work quite so well; since ink and air will not pass through thenarrow slot P so freely and readily and regularly as through the broad slot N. It will =however. make a veryv good fountain pen.

The modificationrepresented.in Figs. 17 to 22 inclusive differs in three particulars from the preferred form :(First.) The back-stay L is not formed. of part of a tube as in the preferred-form; and it has no longitudinal groove in the under side thereof,- but.the under side .is flat. (Second) There is no sub-groove K;

but the bottom side of the feed-rod and fingerv is cut away to fit the round of thebore of the point section. This construction of the feed-rod makes it broader laterally than from the top to the bottom side thereof; and, though not so good as the preferred form, it is better than to have a round feed-rod held in the sub-ehamber. It is held more steadily, so that the feedtongue does notmove sidewise from the center of the pen to so great an extent; and the greater dimension of the feed-rod laterally closes up the ink ways Y, Y, enough to prevent leaking. (Third.) The separating slot W only extends up to the bore of the point section, thereby leaving the feed-tongue short. In other respects this modification is substantially similar to the preferred form. This modification is not so good as the preferred form, though it has the advantage of being somewhat more cheaply made. (First) The back-stay does not hear so evenly upon the back of the pen. (Second.) The sub-groove K in the preferred form allows the feed-rod to be larger, and holds it more firmly. Both the bottom feed-tongue U and the fingerVare larger and stronger in the preferred form, and perform their respective functions better. (Third.) The bottom feed-tongue is more elastic and works much better in the preferred form, from its being lengthened by the separating slot W being August 16, 1892, presents some points of similarity to my present invention; but that patent has not the important features of my present invention,the enlarged ink cup H-the reamed out antechamber Gthe feed-tongue M back of the pen integral with the backstaythe shoulders of the feed tongue abutting against the reamed shoulder gthe backstay L solid at the upper end thereofthe heel of the pen bearing firm upon the bore of the point sectiononly at-the lower end of the bore-the shoulders of the pen abutting against the reamed shoulder gthe Wings of the pen touching the reamed out .point section at the lower end thereof-the air passage F-the sub-groove K-the broad slot N the diaphragm Othe narrow slot P through the diaphragm 0 containing the air inlet Rand the ink duct S.

I have also made application for a patent,

' Serial No. 462,834, filed :February 18, 1893, in

which are some features similar to my present invention. But that application has not the important features of my present invention, the pen held in the bore of the point section by the back-stay L"the back-stay Lthe broad slot N in the back-stay-the diaphragm O in the back-stay-the short narrow slot P in the back-stay, containing the air inlet R and the ink duct Sthe feed-tongue M integral with the back-stay Lthe sub-chamber Inor the sub-groove K. Indeed, my present invention is entirelya different style of fountain pen from that represented in said appli-' cation of February 18, 1893. In that application, the penwas held in a stopperfitting in the point section: In my present inven tion the pen is held directlyin the bore of the point section by the pressure of a back-stay upon the back thereof. In that application, the bore of the point section is almost one fourth of an inch in diameter. In my present invention the bore of the point section is only a little over one-eighth of an inch in diameter. The two fountain pens belong to entirely diflferent classes. I do not wish to claim anything set forth in that patent, or in that bore above said sub-groove and having the sides of its heel in contact with the wall of said bore, substantially as described.
