`FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N o. 444,985, dated January 20, 1891.

Application filed December 17| 1889. Serial No. 334,123. iNo model.)

To all whom t may concern:

Be it known that I, LoUTs BERNHARD, a citizen of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented a neWand useful Fountain-Pen, of Which the following is a specification.

The invention relates to improvements in fountain-pens.

The object of the present invention is to simplify, improve, and cheapen the construction of fountain-pens, secure a regular flow of ink, and prevent theink being fed too rapidly and in too great quantities to the pen and dropping therefrom.

The invention consists in the construction and novel combination and arrangement of parts hereinafter' fully described, illustrated in the accompanying drawings, andv pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective of a fountain-pen constructed in accordance with the invention, the cap being removed. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a transverse sectional view on line a: of Fig. 2. Fig. 4 is a detail perspective view of the elastic plug which retains the pen and feed-tongue in the nozzle. similar view of the ink-shaft. Fig. 6 is a detail view of the nozzle. Fig. 7 is a detail sectional vieW of the pen and feed-tongue.

Referring to the accompanying drawings, 1 designates the pen-barrel, which forms the ink-reservoir and which has its rear end reduced to receive the cap 2 when the latter is not in use, and has its front end 3 interiorly threaded and adapted to receive the threaded end ll of a nozzle 5. The pen G, which is inserted in the front end of the cylindrical bore vof the nozzle, is provided With a transverse opening 7, that is arranged at a point about midway of the ends of the pen and is adapted to receive the rear end of a tongue 8, Whereby the latter is secured to the pen. The feedtongue is provided with a bend 9, which lies in the transverse openingof the pen and is provided with an opening lO to permit the passage of the ink through the feed-tongue to the space between it and the nibs of the pen.

The pen 6 and the feed-tongue 8 are re= tained iirmly in the cylindrical bore of the Fig. 5 is a nozzle 5 by a cylindrical plug, which is elastic and securely holds the pen and tongue against the sides of the nozzle and prevents slipping or wabbling. The cylindrical plug 1l is constructed of rubber or similar material, and is open at the top to permit the pas.` sage of ink, and the .opening 12 of the plug lies directly under the opening` 10 of the feedtongue, and the edgesof the plug at the sides of the opening 12 are slightly flattened in order to increase the bearing-surface and enable the plug to obtain a firm hold upon the pen and also to provide a broad and slightlyflattened seat to conform to the configuration of the inner side of the pen and the portion of the feed-tongue projecting through the transverseopening. Therearendofthenozzleisprovided with a V-shaped or semicircular notch 13, which forms a recess to receive the rear end of a shaft 14, that conveys ink as far as the transverse opening 7 of the pen 6 and which prevents the ink flowing down from ,the under side of the pen to the point and dropping therefrom. The shaft 14 is constructed of rubber or similar material and is slightly sigmoidal in form, which gives it a certain amount of spring and enables its rear end to engage the side of the barrel of the pen through the recess 13 and its front side to bear against the under side of the pen a short distance from the point. The rear end 15 ofthe shaft is pointed and en gages the interior threads of the barrel, and is thereby retained in place and prevented slipping, and the front end 16 is broad and prevents the passage of the inl; to the point of the pen, andl should ink get beyond the end of the nozzle, as may be the casewhen the pen is violently shaken, the shaft la Will conduct the ink back into the nozzle and Will prevent the ink spreading over the outer surface of the nozzle When the cap is fitted in place, as is the case With many fountain-pens. The front end of the |cylindrical plug is sloping and enables the plug to have its body or main portion located Well into the nozzle and still be able to obtain a firm hold upon the pen, and the curved shaft lll extends through the bore of the plug and engages the pen and nozzle upon each side of the plug. By this construction the ink is regularly fed to the point of the pen, but is ICO prevented droppingtheret'roin or accumulating in large quantities'beyond the end of the nozzle, and should the latter occur by violently shaking the pen the ink will be conducted back through the nozzle and be prevented spreading upon the outside of thelatter and causing annoyance.

Having thus described my invention, what I claim is;

l. In a fountain-pen, the Combination of the nozzle, the pen, the cylindrical plug adapted to engage the pen and securely retain it in the nozzle and having the longitudinal opening l2 arranged directly beneath the pen and communicating with the bore, and the slightlyourved shaft. 14, extending throughthe bore of the plug and engaging the penvand preventing the ink reaching the point in too large quantities and `adapted to conduct the ink back into the nozzle, substantial] y as described.

2. t Ina fountain-pen, the combination of the nozzleprovided at its rear endWith a notch 13, the-pen, the elastic cylindrical plug having the opening 12 and being slightly fiattenedfatfeaeh-side `of the.openi'ng,and the curvedv shaft 14, extending through'the bore of the plug and having its rear end fitted in the recess 13 and its front end bearing against the under side of the pen, substantially as and for the purpose described.

3. The combination of the pen provided about midway its length with a transverse opening, the tongue provided at a point intermediate of its ends with a bend arranged in said transverse opening and dividing the tongue into afeeding and aconveyer portion :and'having an opening 10, and the elastic plu g fitting against the feed-tongue and ho1d ing the same and thepen in place, substantially as described.

'In testimony thatl claim/the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

LOUIS BERNHARD.
