FOUNTAIN PEN;
No. 445,600. Patented Feb. 3, 1.891.
' :rm/ENTER UNITED STATES NOYES F. PALMER, OF BROOKLYN, NEW YORK.
FOUNTAlN-PEN.
SPECIFICATION forming part of Letters Patent No. 445,600, dated February 3, 1891.
Application iiled September ll, 1890. Serial No. 364,629. (No model.)
. .To all whom it may concern:
Be it known that I, Novas F. PALMER, of Brooklyn, New York, have invented an lmproved Fonntain-Pen, of which the following is a specification.
This invention relates to an improvement in fountain-pens, and more particularly to a novel construction of the feed-plug that permits a free flow of the inl; and a ready insertion and removal of the pen-nibs.
The invention consists in the various features of improvement, more fully pointed out in t-he claims.
In the accompanying drawings, Figure l is a longitudinal section of my improved fountain-pen; Fig. 2, a side view of the pen-plug; Fig. 3, a longitudinal section thereof; Fig. 4, a top View thereof, and Fig. 5 a cross-section on line x Fig. 3.
The letter c represents the tubular body of a fountain-pen having a screw-tapped end for the attachment of the pen-section b, which is preferably provided with a bell-shaped mouth o. Into the pen-section b there is inserted the pen or nib holding tubular plug c, held within section l) by frictional contact only. The forward `end of plug c is divided by a longitudinal slit c', so as to form an upper feedtongue c2 and a lower feed-tongue c3, between which the pen d is held. The feed-tongues c2 c3 are on their inner faces-MJ. e., the face in contactwith the pen-provided with the longitudinal ink-ducts c c that merge into the main central duct or bore e3 of the plug. This bore is enlargedat its end, as at c4, for the better release or discharge of the air bubbles.
Along the surface of plug c there extends an additional channel or duet e, which com mu-r ,is admitted through the vent f and passes 'discharged ink.
through duct e and channel c3 in a sufficient quantity to compensate for the volume of the As the air passes through the channel e3 and forms bubbles therein, it is apt to interfere with the proper flow of ink, and therefore the second ink-channel e5 is provided, which furnishes an additional and independent supply through perforation f.
AThe ink flowing through this channel does not only supply the `upper face of the pen with ink, but it also flows around the heel of the pen, and thus equally supplies its lower face.
In a fountainpen constructed according to this invention, the ink will flow freely without blotting the paper, and the pen lnay be readily adjusted by drawing the pen-plug to a greater or less extent out of the pen-section.
What I claim isl. The'cornloination of a fountain-pen a with a divided pen-plug having a central feed-duct e3, delivering to the heel of the pen, an upper feed-duct c5, delivering to the top of the pen, and a ventf, substantially as specified.
2. The combination o fa fountainpen a with a tubular pen-plug having a pair of feedtongues, a central feed-oriiice, and an additional duet c5, communicating with the cen tral feed-orifice, substantially as specified.
3. The combination of afountain-pen a with a tubular pen-plug having a pair of feedtongues cr3 c3, ducts e e on the contiguous faces of saidtongues, an additional communicating duct e5, and a ventf, substantially as and for the purpose specified.
et. The combination of afountain-pen d With a pen-section b, having a bell-shaped mouth, and with a tubular pen-plug having a pair of feed-tongues, a central feed-orifice, and an atb ditional communicating duct c5, the pen-plug` being held in the pen-section by frietional contact, substantially as specified.
