FOUNTAIN-PEN.
SPECIFICATION forming part of Letters Patent N0. 239,158,dated March 22, 1881.
Application filed January 26, 1881. (No model.)
To all whom it may concern:
Be it known that I, JOSEPH FRIEDMANN, of Seymour, in the county of New Haven and State of Connecticut, have invented a new Improvement in Fountain-Pens; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1, a side view; Fig. 2, a longitudinal central section; Fig. 3, (enlarged,) a section through the upper end, showing air-valves.
This invention relates to an improvement in that class of fountain -pens which are provided with an air-valve at the upper end, by which airis supplied to'the fount. 1n the usual construction the passage is opened by simply unscrewing the top, depending upouhnscrew ing to a greater or less extent to regulate the flow; but a nice adjustment is impossible, or
an opening so that at all times there shall be t-llle same amount of air admitted is impossib e.
The object of this invention is to make a valve adj ustableindependentof the-cap which opens or closes the passage; and it consists in the construction, as hereinafter described, and particularly recited in the claim.
A represents the fount or tube, which is filled with ink.
B is a plug, which is screwed into the upper end of the tube and fitted with a shoulder, a, to bear upon the end of the tube, and so as to make a tight joint. Above this shoulder the cap C is screwed on in the usual manner. Vertically through the plug Bis a passage, b, and at the lower end of the plug is a trans verse passage, d, entirely through it, and into which the vertical passage 1) opens. In the same axial line as the passage b'a screw-valve, f, is screwed into the lower end of the plug, its end constructed so that when turned in it will entirely close the passage b,- but by turning the screw away from the passage b an opening is formed between the passage b and the screw-valve f for the flow of air into the fount below. By means of the screw f the airpassage may be adjusted by taking the plug from the tube and turning the screw toward or from the end of the passage I), and when properly adjusted it remains so without possible accidental alteration. The cap C has one or more openings, h, through its side, which, when unscrewed, as seen in broken lines, Fig. 3, communicates with the passage 1). Because of the adjustment of the screw-valvef, itis immaterial to what extent the cap is raised, only that it be raised sufficientl y far to bring the opening it above the end of the plug. The screw-valve f is preferably of larger diameter than the passage 1), and its end made conical to fit a corresponding seat at the lower end of the passage 0, like a puppet-valve. The special device to which this valve is adapted and shown in the drawings, is for a fountain to be used with a common pen, and in which the opening from the reservoir comes upon theinside of the pen, as shown in Fig. 2.
The lower end of the fountain is closed by a plug, D, having an ink-passage, n, longitudinally or vertically through it. Into the lower end of this plug the tip E is screwed, and the plug preferably constructed so as to leave a cavity, m, around the body of the tip. The tip has an opening, 7, on the pen side, into a chamber, .9, within the tip, and from the passage n a passage, it, leads through the body of the tip into a tube, F, within the chamber 3, the said tube extending down nearly to the opening r. The ink flows through the passage n in the plug, thence through the passage 13 into the chamber 8, then through the tube F to the opening 1". The chamber sforms a space around the tube F, above the outlet of the tube. The supply from the fountain keeps the opening 1" and the space up to the mouth of the tube filled with ink; but the space around the tube cannot be filled, because the air therein cannot escape; hence the space in the chamber below, and at the opening 1',
which is much larger than the passage in the tube F, will remain filled with ink, and when the air-valve above is closed the air in the space around the tube F will hold the ink in the large space below the tube and prevent its flowing outside--that is, the ink at that point will be held in suspension. This arrangement enables a larger opening, 4", and space about it than can be employed in the usual construction of tips, and because of the larger space and greater amount of ink there is less liability for the ink to dry up, thicken, or clog.
I claim In a tubular fountain-pen, the plug B, fitted 10 to the upper end of the tube, constructed with a Vertical central air-passage, I), combined with a screw-valve, f, adjustable to the lower end of said passage 1), and a cap fitted to close the upper end of said passage, substantially as described.
