Application mea october 23, 1919. stel-iai No. 332,678.
To all whom it may concern:
Be it known that I, HUGH lViLsoN HAsLUP, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful improvements in Fountain- Pens; and l 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 figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in fountain pens, or, rather, to-the pen-holder of such pens, and while it is adapted Vfor use with many kinds of fountain pens, it is espe- A the like.
cially well adapted for application in connection with self-filling pens of the sort illustrated in the patent to Schaft, of June 30, 1903, No. 732,117.
The barrels of the holders of pens of this class, as usually manufactured, are formed at each' end of specially shaped and unlike portions, as well as unlike slip-joints and The necessary special manipulations of each end of the barrel, as well as the connected parts, require time and extra labor, resulting in added cost.
It frequently happens that pen manufacturers are seriously delayed -in the production of their pens by the lack of the peculiarly shaped stock necessary for the specially formed barrels of their pens.
Another difficulty encountered by fountain pen manufacturers is that joints between the pen-section and the barrel of the holder frequently become weakened by the splitting or breaking of the thin threaded portion of one of these members, thus rendering the pen-section loose and insecure in its holder, which results in the loss of the entire holder.
The objects of my invention are to overcome the objections above indicated, and, more particularly, to provide a barrel-portion for pens which portion shall be composed of vulcanized rubber tubing of uniform gage and bore, such as may be at any time readily procured by pen manufacturers from rubber manufacturers, which tubes may then be quickly sawed into the required barrel-lengths and threaded at each end as may be required, thus avoiding the delays and expense attending the production of barrels of special construction. A further object of my invention is to provide the barrel-sections here referred to with internal socket. A further obj ect of my invention is to provide a construction which in the event that the rubber ink-container fails as a selffiller, permits the pen to be readily converted into a drop-filler.
To these ends, and with other objects in view, my invention consists of the devices and construction hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my pen with its screw-cap in place but shown in central longitudinal section; Fig. 2, the
same without the screw-cap and showing the barrel of the pen, the pen-section and the end-plug in central longitudinal section, and Fig. 3 the same, showing the pen-section and the end-plug detached and slightly withdrawn from their sockets in the barrel-section.
Like reference-numerals indicate parts throughout the drawings.
In the drawings, 1 is the barrel of my like Ipen-holder, composed of a length of vulcanized tube of suitable length and of substantially uniform diameter and bore throughout its length. 2 is the pen-section, of the usual or any preferred construction, and 3 is the plug-section of the pen-holder. At each end, the barrel is internally threaded, as at 4L, these threads being uniform. The pen-section 2 is threaded as at 5, and the plug-section 3 is threaded, as at 6, these threads being adapted to engage, interchangeably, either of the threads 4.
7 is a soft rubber tubular ink-reservoir, one end being secured to and closed by the neck of the pen-section, as at 8, the opposite end of the part 7 being provided with and closed by a projecting stem 9. The interior of the tube 7 is in communication, through the pen-section, with the pen 10.
The twisting of the stem 9 contracts and eX- pels the air from the tube 7 The pen being dipped in ink, the release of the stem permits the tube to untwist and to resume its normal shape, thus forming a partial vacuum which causes the ink to flow into and to fill the tube.
To obviate undue length of the barrel-section, I prefer to make the plug 3 hollow, as at ll, the cavity being of suiicient dimension to receive the stem 94, as illustrated in Fig. 2. It will be seen that the stem 9 thus becomes readily accessible for operation by merely unscrewing the plug-section 3.
12 is a cap which protects the pen when not in use and which may be slipped over the plug 3 when the pen is in use. I prefer to thread the barrel-section and the cap, as at 13--11l, to provide against the escape of ink when the pen is not in use. Ordinarily this external and internal threading of the barrel, as at 4.-14, is not feasible, as it too greatly weakens the thin wall of the barrel at this point, but in the constructionhere shown it becomes practicable, since the end orn the barrel is internally supported and strengthened by the threaded portion of the pen-section.
It will be seen that should the tube 7 for Vany reason become inoperative, it may be Having described my invention, what I claim and desire to secure by Letters Patent of the United States is,-
l. In a device of the described character, a pen-section, a llexible tubular ink-reservoir, one end of which leads into said pensection and having at its other end a projeeting stem, a plug, chambered for'the reception of said stem, a barrel for the reception of said ink-reservoir, said barrel being uniformly internally threaded at each end, said pen-section and plug-section being, respectively, uniformly externally threaded for interchangeable engagement with said internal threads.
2. A device of the described character, comprising a barrel-section, a pen-section, a plug-section, and an internally threaded cap adapted for engagement with either end of said barrel, a flexible tubular ink-reservoir leading at one end into said pen-section and having at its other end a projecting stem, there being a recess in said plug-section for the reception of such stem, said pensection and plug-section being adapted, respectively, for interchangeable engagement with either end of said barrel-section.
In testimony whereof I aliix my signature in presence of two witnesses.
