To all whom it, 7210.3/ con/cern: e

Be it known that I, PAUL E. WIRT, a citizen of the United States, residing at Blooms-f burg, in the county of Columbia and State of Pennsylvania, have invented a new and useful Fountain-Pen, of which the following is a specification.

This invention relates to fountain-pens,andl more especially to the means for controlling' the supply 0f ink forthe pen, and in this particular is designed principally as an im prove-, ment upon the invention set forth in my pend.` ing application, Serial No. 739,29S,f1led De; cember 5, 1899. A.

In the form of fountain-pen disclosed in the:` aforesaid application the holder or barrel is. provided with well-defined separate main sup-i ply and service reservoirs in addition to or apart from the duct leading to the pen andg which reservoirs respectively hold the main; supply of ink and a pre-determined supply for service. In the said construction there is alsoi associated with the said two reservoirs, suit-2 able means for totally cutting off communi-` cation between the 'two reservoirs, when the? pen is either in or out of use, but which means is primarily designed to cut off communication from the main supply of ink in the main reservoir, as long as there is a sufficient quantity of ink in the service-reservoir for supplying the pen. In the above-described construction disclosed in the said pending application the different forms of valves employed have a longitudinal movementwithin the holder or barrel, therebynecessitating the employment of a rod or stem which must be withdrawn and pushed in again in the manipulation of the valve; and the main and primary object of the present invention is to dispense with the use of valves of this character and to substitute in place thereof a suitable valve which will not only constitute the separating-diaphragm between thetwo reservoirs of the holder, but will also be 'provided with a member rotatable in :substantially the plane within which the valve is located, thereby rendering the structure cheaper and easier to make, besides being cleaner to operate, by dispensing with a sliding rod or stem and obviating the necessity of making provision for the protection of joints.

With these yand other objects in View, which will readilysuggest themselves to those skilled in the art as the nature of theinvention is better understood, thefsame consists in the novel combination and relation of parts hereinafter more fully described, illustrated, and claimed.

Broadly speaking, the invention contemplates the employment of a valve occupying a fixed location between the main and supplemental reservoirs of the holder, which valve includes a rotary member having no appreciable movement away from the plane in which the valve is located, and, specifically, the invention contemplates a movable Valve member having a rotary or axial movement; but the'particular type of Valve used for the purpose stated is necessarily susceptible to a variety of modifications without departing from `the spirit or scope of the invention, yet the preferred form of valve utilized in carrying out the invention 4is shown in the accompanying drawings, in which- Figure 1 is alongitudinal sectional view of a fountain-pen fitted with one form of valve, which form of valve not only acts as a cut-off, but also forms the supplemental service-reservoir,Y which isin communication with the ink-duct ofthe pen. Fig. 2 is a detail in perspective of the two members of the form of valve shown in Fig. l, said members of the valve being illustrated as separated. Fig. 3 is a longitudinal sectional view showing a modification in which the form of valve illustrated in Figs. l and 2 is associated with a swelled form of' holder or barrel. Fig. 4 is a similar view showing 'another form of valve combined'with the swelled form of holder. Fig. 5 is a detail in perspective of the two members of the valve shown in Fig. 4. Fig. 6 is a longitudinal sectional View of a fountain-pen, showing the disk: form of valve combined with a straight holder or barrel. Fig. 7 is a longitudinal sectional View showing a modification in which the operating member for the valve is exposed at the lower or pen-carrying end of the holder. Fig. 8 is a detail in perspective of the two members of the valve shown in Fig. 7, said members of thevalve being illustrated as separated. Fig. 9 is a detail view, partly in section, of the axiallymovable or rotary valve member shown in Figs. 'and 8 and illustrating a modification VIO to the duct. ,is usually accomplished by properly contractin gthe channel leading ink to the pen, whether Y [this channel be in the nozzle, the pen-section itself, in the feeder lying under or above the of the joint connection between such valve member and the pen-bearing section. Fig. 10 is a longitudinal sectional view, partly in perspective, showing a modification involving tubular valve and valve-seat members constituting the lower supplemental service-` reservoir and valve-disk members for controlling communication between the two reservoirs.

Like numerals of reference designate cor-v responding parts in the several figures of the drawings.

As already explained, the present invenl tion is utilized in connection with a holder orV barrel having separate interior main supply and service ink reservoirs in addition to the usual ink-duct 'leading to the pen, and in thisv connection it may be observed that the lower or supplemental service-reservoir of the peny holder is separate and distinct from the inkduct with which fountain-pens areu'sually` provided. Such ink-ducts have an independ- -entfunction-namelyno assist in properly;

gaging the outward ow of ink to the pen and regulating, to some extent, the entrance of air to supply the space made by the ink being withdrawn from the reservoir adjacent The provision of the ink-duct pen, or in both. It will therefore be understood that the present invention, as well as the invention set forth in my aforesaid application, contemplates a structure in which the two reservoirs in the holder are entirely sup plemental to or apart from the usual ink-duct,

.and the present invention relates specifically tothe lprovision of a suitable valve, which is adapted to be iixedly positioned so as to conjsti-tute a separating-diaphragm between the forms or shapes of holders; but in Fig. 1 ofv the drawings the numeral 1 designates a penholder or barrel straight through its length and `constructedwith a large interior main supply-reservoir 2,which occupiesthe greater portion ofthe holder and is of a maximum l capacity, so as to contain a large supply of ink, which is held in reserve for use in re- ,plenish'ing the service-reservoir, hereinafter referred to. In this forni of holder, as well as in all other forms,the same may be provided 4at one end thereof with any suitable form .of pen-bearing section 3, carrying the Vpen 4t and 'feeder 5, as well as having the usual cessful-carrying out of the invention what vtype of pen and feeder I employ nor special ink-duct 6 but it is not important to the suc- `at its opposite end, as at 9. ,lies longitudinally within the holder and is 2 simpre?? arrangement Vof these members. It is only necessary that there be associated with the holder having the duplex or double reservoirs suitable means for delivering the ink to the pen by capillary attraction. However, in addition to the ink-duct 6, `irrespective of the position or formation of this duct, there is provided in addition to the main supply-reservoir 2'of the holder a supplemental servicereservoir 7, which is made as large as possible andis ordinarily of about as great capacityas the average-sized chamber or space within the ordinarysized fountain-pens now on the mar- KVket. The said supplemental service-reservoir 7 directly adjoins the ink-duct for the pen. In the form of the invention shown in Fig. 1 the said supplemental service reservoir is preferably in the form of a tube 8, open at the end contiguous to the ink-duct and closed The said tube 8 permanently tted therein in a stationary position, preferably near the lowerend thereof. The said tube 8 i s also `of a less width than the main supply-reservoir 2 into which it projects and forms the fixed valve-seat member of a valve designated in its entirety by the member 10, whereby this valve will constitute a separating-diaphragm between the two reservoirs 2 and 7. The fixed valve-seat member 8, which forms the service-reservoir 7, is provided therein, preferably in the side thereof, with a port 11, which when uncovered is in communication with the main su pply-reservoir, whereby ink may pass to and from said reservoir through the port 11, and the covering and uncovering of the port 11 in the fixed Y valve-seat member 8 is accomplished through the medium of an axially-movable or rotary valve member 12. VThe movable valve memg ber 12 is preferably in the form of a cylindrical 1,3, and is provided in its side with a valveopening 14, which is adapted to aline and disalinewith the port 11 in the stationary member ortube 8. The said valve member or cap 12 has suitably connected to one end thereof the inner end of an axially-movable valvestem 15, the outer end of which stem is tted to an adjusting-knob 16, having a threaded boss 17, turning in a threaded flange or socket 1S, at the upper end of the holderor barrel 1. It will thus be seen that by simply turning the knob 1G in either direction the movable valve member or cap 12 is caused to turn upon the fixed valve member or tube 8 to-provide for opening up or closing communication between the two reservoirs 2 and 7 at the will of the operator without the necessity of sliding the valve-stem in and out of the holder in the manner shown in my aforesaid pending application. l

When it is desired to fill or replenish the IOO IIO

lower supplemental service-reservoir 7, the movable valve member or cap 12 is turned to bring the openings 14 and 11 into communication, thus permitting a supply of ink to run from the main reservoir 2 into the servicereservoir 7, and after sufficient ink has been supplied to the said reservoir 7 the movable valve member or cap 12 is turned to disaline the openings 14 and 11, thereby entirely cutting oif the main supply ot' ink within the reservoir 2 from the main supply in the-reservoir 7. When the pen is not in use, the valve maybe manipulated to open up communication between the two reservoirs, so that by inverting the pen all of the ink in the lower or service reservoir 7 will drain back into the main reservoir 2, and may be held in the latter by again closing the valve, thus making it safe to carry the Apen in any position.

In Fig. l of the drawings the form of valve described is shown applied to the holder 1 straight through its length; but the same form of valve can be used in connection with a holder having an intermediate annular enlargement or swelled portion l, such form of holder being shown in my aforesaid application.

In those forms of the invention where the lower or supplemental service-reservoir is formed directly in the body of the holder or barrel itself a different type of valve may be employed, such as shown in Figs. 4, 5, and 6 of the drawings. In the said form of the invention the lower or supplemental service-reservoir is designated bythe reference character 7a, and the necessary separation between the said reservoir and the main supply-reservoir 2 is maintained through the medium of a valve 19, which valve is arranged in a fixed location between the two reservoirs. The said valve 19 essentially consists of a xed valve-seat member 20, permanently itted in a stationary position within the holder and the movableA or rotary valve member 21 cooperating with the said iixed member 20. The said valve members 2O and 21 are in the form of flat circular disks arranged one upon the other and provided, respectively, with the posts 22 and 23, which are adapted to be alined and disalined by the axial or rotary movement of the movable member 2l, and said movable valve member or disk 21 is fitted on the inner end of the axially-movable valvestem 15, said inner end of the stem also eX- tending through a bearing-opening 24 in the xed valve-seat member 2O to provide for holding the disk or rotary member 2O in proper working relation to the said valve-seat member.

member 2l in either direction communication between the two reservoirs 2 and 7a may be controlled in the same manner and for the same purpose as the herein-described form of valve shown in Figs. 1, 2, and 3 of the drawings.

In Fig. 4 of the drawings the disk valve 19 By simply turning the rotary valve is shown applied to the swelled form o'fholder or barrel, while in Fig. 6 it is shown as applied for use in connection with the straight form of 'holder or barrel.

In the forms of the invention already described the operating member or device for the movable valve member consists of an axially-movable valve-stem 15carrying an adjusting-knob exposed at the inner or upper end of the holder; but it will of course be understood that other means might be resorted to for adjusting or manipulating the adjustable or rotary valve member and such means controlled Vfrom either the upper or lower end of the holder. To illustrate the modifications that might be resorted to in this particular, there are shown in Figs. 7 to 10, inclusive, a novel and effective construction and arrangement of parts, whereby the valve or cut-od may be operated from the lower or front end of the holder, thus dispensing entirely with the use of the stem or rod runninglongitudinally through the holder, as shown in the other forms of the invention.

Referring to the modifications illustrated in Fig. 7 of the drawings, it will be seen that this modification involves the use of the same type of valve as shown in Figs. l, 2, and 3 of the drawings, which type of valve includes tubular valve members registering one within the other and one of which is fixed and the other axially movable to provide for the alinement and disalinement of the ports thereof. In the modification, however, the tubular valve members are arranged somewhat diiferently, and by reference to Fig. 7 of the drawings it will be seen that the fixed valve-seat member Sa is provided at the lower open end thereof with an interior-threaded collar 25, adapted to abut against the lower end of the holder 1 and contiguous to such collar with an exteriorly-threaded portion 26 engaging the interior threads 27 at the lower end of the holder to provide aconnection for fixedly holding the valve-seat member 8 in position within the holder, while at the same time permitting of the ready removal and replacing thereof whenever necessary. The said stationary or fixed valve-seat member 8, like the corresponding member 8 in the construction shown in Figs. 1, 2, and 3, is in the form of a tube open at its lower end and closed at its opposite end, as at 9, and eX- tending inwardly within the holder and longitudinally thereof. The said tubular valveseat member 8 is also provided with a port 11, which when uncovered is in communication with the main supply-reservoir, whereby ink may pass to and from the said reservoir for the purpose and in the manner hereinbefore fully set forth; but in the modification shown in Fig. 7 the xed tubular valveseat member 8n is adapted to have the axiallymovable or rotary valve member 12a working inside of the same instead of on the exterior thereof, as the corresponding valve member 12. (Shown in Figs. 1, 2, and 3.)

This of course is a mere inversion of the relation'of the 'valve'members from` that already described and does not change the function or operation of the parts; but in order to secure the necessary manipulation or adjustment of the tubular movable valve f member 12a the latter carries a nozzle 'portion j 28, which is arranged exterior to the holder; 1 at the lower end thereof and confines the,` ink-duct 6, as well .as being adapted to receive in the extreme outer end thereof the; pen-bearing section 3, which may be ittedin lthe said nozzle either by means of a slip: vjoint, as shown -in Fig. 7, or bya screw-joint l" 28, as shown in Fig. 9 of the drawings,either1l form of joint between the pen-bearing sec` tion and the nozzle 2S of the movable mem-V 4ber'permitting the said pen-bearing section, to be readily removed for the purpose ofi changing the pen or to refill the holder -with fst-.1.757.

a fresh supply of ink when the supplyof both -reservoirs has become depleted. The axi-y ally-movable or rotary valve member 12a is necessarily in the form of a tube and is `pro-` vided in its side with a valve-opening 14, adaptedV to aline and disaline with the port ll'vin the tubular stationary valve-seat Amember 8*,'and atan' intermediate point between.

its'ends the said tubular valve 1nemberl2a lis provided with an exteriorly-threaded portion 29, adapted to engage within the extoriorly-threaded collar 25 to'provide for -holding the valve member 12a in proper relation Vto the valve-seat member 8, while at the same time permitting of the necessary rotation of the said valve member 12 to secure' thevalinementand disalinement of the opening 14-a with the port 11a. It will be obvious that to turn the valve member 12a it is only necessary to grasp the exterior nozzle portion 28 with the fingers, as such nozzle vand the valve necessarily constitute a finger-grip.

In the construction described Vthe tubular` valve, consisting of the valve-seat and- valve members 8 and 12, forms the lower-or supplemental service-reservoir, and therefore performs the same function in the same relation as the corresponding valve members shown in Figs. 1, 2, and 3, and another modication involving the manipulation of Ithe valve from the lower end vof the holder is shown in Fig. 10 of the drawings. The construction illustrated in this gure of the draw- `,ings is, in elect, a modication of that shown in Fig. 7 and simply involves a differentdis- -position of the ports of the valve-seat andY movable valve members. In this arrange-1 ment the fixed tubular valve-seat member 8? isprovided at its inner end within the holder Vwith a valve-seat disk 30, provided therein with a segmental port 31, adapted to aline and disalinewith a correspondingly-shaped The 'modified `constructions illustrated in Figs.,7 to 10, inclusive, while shown in connection with the swelled form of holder, could obviously be utilized with lthe vstraight form of holder without aecting the operation or result accomplished.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described fountain-pen will be readily apparent to `those skilled in the. art without further description, and it will `be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
