FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 508,182,dated November 7,1893.

Application filed March 19,1891. Renewed October 9, 1893. Serial No 487,657. (No model.)

To all whom it may concern:

Be it known that I, HUGH T. REED, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain-Pens; and I do hereby declare that the following is a full,

clear, and exact description thereof, reference 7 being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to fountain pens of that class which are provided with a reservoir for the ink in conjunction with a point section carrying the pen and having suitable means for feeding the ink to the pen, said point section being inserted in the lower end of the reservoir.

The object of my invention is to simplify the construction of the pen by dispensing with the cap usually employed to close the pen when not in operation, and to this end it consists in certain features which will hereinafter be pointed out.

Referring to the drawings: Figure 1 is a sectional view'of a fountain pen embodying my invention in one form,'the parts being in position for use in writing. Fig. 2 is a view similar to Fig. 1, showing the parts in position to close the pen when not in use. Fig. 3 is a plan section taken on the line 3-3 of Fig. 4 is a plan section taken on the line 4-4 of Fig. 2. Fig. 5 is a sectional view showing a modified form.

In the construction shown in Figs. ,1, 2 and 4, A represents the body of the pen, which forms the reservoir and which consists of a hollow cylinder permanently closed at its' end portions, b, b, separated by a collar, b

These end portions are either cylindric or conical to adapt them to fit snugly within the open endof the reservoir A, the collar 1) forming a stop to limit the motion of the point sec- .tion when thus inserted, by abutting against the end of the reservoir.

0 indicates the pen, which is inserted in the end portion 19 of the point section B, this latter being provided with suitable feeding devices communicating with the reservoir and with the pen to supply the pen with ink when in operation. The means employed for this purpose may be any particular kind, but I prefer the construction shown, which is that set forth in Patent No. 449,295, issued to me March 31, 1891.

In this construction the point section B is made in the form of a hollow cylinder, open at both ends, and there are inserted in the passage thus formed within the point sections, plugs D and E, one or both of which may be revoluble in the said point section.-

In practice I prefer to have the pen-carrying plug D fixed within the point section and in this case the other plug E will be revoluble. For this purpose the plug E is slightly reduced atits end, as shown at E, the shoulder thus formed abutting against a corresponding shoulder W, in the interior of the point section. In the assembling of the parts, the plug E is first inserted in the bore of the point section, and when it is in place in the position shown, the plugD is then inserted, and this latter, be ing somewhat conical or tapering, will fit firmly within the bore of the point section; it will thus be seen that'the plug E will be held from longitudinal motion between the plug D and shoulder 12 while at the same time it may be freely rotated, being provided for this latter purpose with a transverse slot 6 at its exposed end, in'which a knife blade or other similar article may be inserted for the purpose of rotating said, plug. The plugs D and E areprovided with longitudinal ink feeding grooves, e",in their external surfaces and constituting when inclosed by the point section, as shown in Fig. 3, ink passages by means of which the ink is conducted from the reservoir to the pen. The plug D is pro vided with a pen slit extending into the grooves e, and with the usual prong F for ICO constructed, it will be seen .that when .the

parts are in theposition shown in Fig. 1,*the

pen is ready for use and operates in the usual manner. When it is desired to close the pen for the purpose of carrying it in the pocket, the point section is withdrawn :from the reservoir, reversed, and inserted in this reversed position in the reservoir, as shown in Fig. 2. The end I) of the pen .section which has just been withdrawn from the reservoir, is then wiped and the pen may be placed in the-pocket and safely-carried with-. out danger of spilling-theink. .Sinceithepen will ordinarilybe carried upright in the pocket and the ink passages through the point section are-very sniall,I- do not considerit inall cases I .necessaryto provide means for closing said'ink passages when .the point section .is reversed, I but some device for this purpose is, .as a rule, desirable, and Iprefer that shownin Figs. 1,2, 3,and 4;. In this construction 'it:is onlynecessary, when-the point sectionhas been re-i versed, to revolvethe plug .Eslightly, in the manner hereinbefore set forth, when the'ink' passages will beclosed and any escape of the. inkfrom the pen absolutelyprevented. (Dther means for .e'ifecting this closure of .the ink: passages may be employed, and as an .in-

stance I haveshown, in .Fig. 5, a constructionf embodying a modification ofthisfeature. :In I this figure the lower end of the .reservoir A'tis shown as threaded'internally, while the ends, bib of the point sectionB areshown ascorre 'spondingly threaded externally. Thismeans of connection ofthe reservoir and point sec-j tion may ,be employed in the construction; shown in Figs- 1 to 4, or the smooth "fit shown in .those figures maybe employed'in the construction shown in Fig. 5. In this latter fig-i .ure, thepointsection is provided with afixed* internal ,plug G, carrying the ,pen and have ingit-heilateral ink passages g, substantially as .hereinbefore described. The otherend of theboreof the point section is threaded ;in-. :ternally,to receive a screwplug G provided with .a central ink .passage, 9', and with a transverse slot or notch, g at its outer end byimeans of which said plug maybe rotated. It wilLbe seen thatby rotating ,the-screwplug G in the proper direction it maybe caused tmadvance towardor reeedefrom theplug G. Whenthe-plug G is'in contactwith the plug' G, it is obvious that the end of eachplug will close the passages of the other plug, since these passages do not register, and theflow of the ,ink will thus be cut off. If the plug Gberotated so .as to form a slight spacebetweenitand the plug G, this space wiltform -a communication between the central .pas-

sage g of the plug G and thelateral passages I got the plug G, thus permitting the ink .to' flow ,freely through the pointsection. 'It will also be seen that the size of this space "between the plugs, which isdeterminedby thej position of the screw plugG", regulates the: .flow of the ink.

Pens of this description have heretofore consistedof three essential rparts the reservoir, the point-section and the cap. In the manipulation of these three parts it is obvious that only two of them can conveniently .beheld in the twovhands of the manipulator, the third part, generally the cap, being laid down in the first convenient place, and thereiby-firequently mislaid and lost. On the other hand, in my construction there are only two essential elements, the reservoir and the point section, the ilatt-erwforming a closure for the tresenvoirinzeither .of .its ,positions, thus dispensing with the cap. Moreover these two essential elementsare exceedingly simplein their construction, ithe bodyof' the pen, which .formsthezreservoir,:being simply a'hollow cylinder open at one end,while'thegpoinhseotion .is .essentially .a simplecylinder adapted ;to ,receive the pen and having feeding devices. 'Thissimplicityof construction; is not only a very desirablefeature iniitself, but/it also en ablesmeto greatly reduce the costof manufacture.

W'hat'I claim is- 1. A ;foun tain pen comprising a tubular body portion open at on e.end and closedat :theotherand forming the ink reservoir, and .a reversible point'section, eachend of which {fits theopen end of the tubularbody portion, said point section being provided with an .inkpassage andmeans for regulating theconductive capacity of said passage, substantiallyas described.

2. A fountain pen comprising a-tubular body portion open at one end and closed at the other and forming the ink reservoir, a hollow reversible point section, each end of which fits the open end of the*tubular;body ,portion and one end of which 'isclosedsave for a relatively small ink passage,.a rotatable plug fitting the interior of said section and provided with an=inkpassage normally forming an extension of the passage throughthe closed endof the section,the adjacent ends of said passage being at one side of theaxis of the rotatable plug whereby communication between said passagesmay be cut olfby rotating the ,plug, substantially as described.

3. A fountain pen comprising a tubular body portion open at one end and closed at the other and forming the ink reservoir, a hollow reversible point section, each end of which fits the openend of said tubular-body portion, a stationary anda rotatable plugfittingthe bore ofsaidpoint section with their adjacent endsjin contact and a longitudinal groove on the surface of each plugfforining a passage for the ink, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signatureimpresence of two witnesses.
