JNVENTOR. JULIAN GUTIERREZ MARBAN United States Patet FILLING DEVICE FOR FOUNTAIN PENS Julian Gutierrez Marban, Havana, Cuba Application December 13, 1956, Serial No. 628,170 Claims. (Cl. 141-30) This invention relates to filling devices and has special reference to a filling device of the type adapted for injecting iluid into the reservoir of a writing instrument of the fountain pen type.

More particularly, this invention relates to a device for lling a fountain pen of the type having a writing element, a refillable reservoir and a member providing a self-sealing passageway communicating with the reservoir, this device including a container having a discharge aperture therein and pressure means operable from its exterior, and an open ended tube projecting outwardly from the con tainer for detachable engagement with the self-sealing passageway for filling the reservoir and being movable to a second non-filling position, there being a valve associated with the discharge aperture and the tube for directing communication therebetween when the tube is in the filling position.

In the filling of the usual type of fountain pen with writing iiuid, it is usually necessary to completely immerse the writing element in a body of writing fluid to insure that a full supply of uid is drawn into the reservoir upon manipulation of a lever or plunger actuated mechanism disposed internally of the pen barrel. Thus, upon completion of the lling operation, a substantial quantity of fluid normally adheres to the writing element and gripping section and it is necessary for the user to remove this excess iluid with a tissue or cloth to prevent it from blotting the writing surface or soiling his hands or clothing during subsequent use of the fountain pen. In addition, the expansion chambers of the feed ba-r should be drained of excess fluid to permit them to function properly immediately after filling.

The parts of the lever or plunger actuated filling device incorporated in the usual fountain pen are normally relatively small due to the restricted space available for them in the 'bar-rel. The relatively small size of these parts requires careful handling in assembling and servicing the pen and this tends to increase the costs of production and subsequent maintenance. Also, the size and weight of the usual pen cannot be reduced as much as some users would prefer due to the necessity of providing space for ice ` tain pen filling device which contains all of thestructure the filling device in the barrel, while still maintaining adequate reservoir fluid capacity.

These problems have long been recognized in the art and various suggestions have been made for their solution. As an example, it has been proposed to provide a pen having a reservoir barrel adapted to be removed from the writing element and filled by pumping or drawing a quantity of uid thereinto. This proposed solution has met with very little if any commercial success because of the complications which arise when attempting to handle and assemble the lled barrel with the writing element.

Accordingly, it is one of the objects of this invention to provide a fountain pen filling device which eliminates the necessity of contact between the writing liuid and any exterior portion of a pen.

Another object of this linvention is to provide a founnecessary to move fluid into the reservoir of a penso that the pen may be simply constructed and have a larger fluid reservoir resulting from the elimination of any filling structure therein. i

A further object of this invention is the provision of a fountain pen filling device which will move a predetermined quantity of fluid into the reservoir of a pen.

A still further object of this invention is to provide a fountain pen filling device which will not over fill a foun tain pen reservoir regardless of the quantity of the iiuid retained therein before being filled or of the number of actuations of the lling device.

An additional object of this invention is the provision of a fountain pen filling device which requires few parts, which is inexpensive to manufacture, which may be simply and ruggedly constructed and which can be operated readily and safely without undue care ou the part of the user.

A still further object of this invention is to provide a fountain pen filling device which will fill pens of various sizes and reservoir capacities in a positive and efficient manner, which can be refilled easily itself and which can lbe adapted as a desk appointment for both storing and filling a fountain pen.

Further and additional objects will be apparent from the Vfollowing description, when taken with the accompanying drawings in which:

Fig. l is a longitudinal sectional view of a fountain pen lling device constructed in accordance with a preferred embodiment of this invention and shown assembled with a pen; f

Fig. 2 is an enlarged fragmentary view of the pen and the pen receiving socket portion of the filling device shown in Fig. l;

Fig. 3 is a fragmentary view of the pen receiving socket portion of the lling device shown in Fig. 1 when assembled with a closure cap;

Fig. 4 is the same as Fig. 1 except that the parts are shown in another position;

Fig. 5 is a broken isometric view of another lling device constructed in accordance with a second embodiment of this invention; and

Fig. 6 is a longitudinal sectional view of an additional filling device constructed inaccordance with a third embodiment of this invention.

Referring now to the drawings and more particularly in Figs. l through 4 thereof, a filling device 10 is provided which consists of a relillable fluid container 11 having threadedly or otherwise secured thereto removable cap 12. While the container 11 is shown as being made from a transparent material, preferably glass or plastic, it is understood that this part may also be made of a translucent or opaque material. The removable cap 12 is preferably formed from a relatively rigid and break-resistant material.

An auxiliary well 13 having a closed lower end is frictionally or otherwise supported within the container by cap 12. The auxiliary well 13 includes a longitudinal lbore 14, a uid intake 15 and an internal discharge aperture 16. A trough-like huid collector 17, which preferably is formed of a metal which will not react with a writing fluid, is supported within container 11 by auxiliary well 13. The fluid collector 17 is held in a fluid-tight relationship with auxiliary well 13 so that the writing uid collected therein may enter diuid intake 15, the lower wall of collector 17 being adjacent the lower surface of intake 15.

Pressuremeans comprising a piston 18 is slidably received in bore 14 and rod 19 is threadedly or adhesively secured topiston 18. yRod 19 extends through opening 20 in cap 12 and is frictionally or otherwise secured in bore 21 in grasping member 22. Piston 1S is preferably made from a relatively resilient rubber or plastic material which will not react with writing uid. Rod 19 should be made of a good ygrade of stainless steel or some other material which is also inert to writing uid.

Grasping member 22 is shown in this embodiment to be threadedly engageable with the interiorly threaded projection 23 on cap 12, although other engaging means may be used. Gasket 24, which is preferably of a resilient rubber or plastic material, is carried on rod 19 in abutting relationship with the lower surface of grasping member 22 to seal opening 20 from the atmosphere when the filling device is in the non-filling position. Although not illustrated in this embodiment, gasket 24 may be replaced by a seal gasket held stationary by cap 12, with rod 19 slidable through a bore in the gasket. Washer 25, made of felt or other similar absorbent material, is disposed around opening 20 in cap 12 for the purpose of absorbing any writing fluid which might inadvertently pass through opening 20. `As an added safety precaution measure, opening 26 is provided adjacent the top of the auxiliary well 13 to allow escape of any fluid which might be trapped aborve piston 18 as it is drawn upwardly in bore 14.

Hollow chamber portion 27 is supported in container 11 by means of supporting member 28 which is secured to auxiliary well 13. The chamber portion includes an inlet 29, an outlet 30 and a seating segment 31 surrounding the outlet 30. Passage means 32, which is preferably a small diameter ilexible plastic tube is frictionally or adhesively mounted in discharge aperture 16 and inlet 29 for providing fluid communication therebetween.

An open ended hollow tube 33 is reciprocably mounted through aperture 34 in cap 12 and on the portion projecting into the container 11 it is provided with a closure element 35 which is frictionally or otherwise secured thereto. Closure element 35 is molded or formed from a resilient rubber or plastic material and the lower surface thereof is adapted to cooperate with seating segment 31 to form a valve for closing outlet 3i). This valve may have tapered cooperating surfaces, as shown, or at or other surfaces. In the embodiment shown, a metal insert 36 is molded or otherwise inserted in a recess in the closure element 35 to provide a means of retaining the closure element rigidly on the tube in the desired position. The upper surface of the closure element 35 is adapted to abut the under surface of the cap 12, as illustrated in Fig. 4, to seal the aperture 34 upon removal of a fountain pen 37 from the filling device.

As best illustrated in Fig. 2, tube 33 is provided with a collar 38 which has an upwardly flared ange 39 around its upper periphery as well as a substantially vertical aperture 40. The upwardly flared flange 39 and aperture 40 are provided in the collar 38 for the purpose of providing a path for uid to re-enter the container 11 during disassembly of the pen 37 from the filling device in the event any fluid found its way inadvertently `out of the tube 33 or refillable reservoir 41 during the Vfilling operation. Collar 38 is profvided with a shoulder 42 adapted to receive a resilient member 43 which is disposed between recessed cap surface 44 and the shoulder 42 for urging the tube 33 to an extended non-filling position upon removal of the pen 37. An upwardly extending tubular portion 45 is provided on the cap 12 as a means of limiting the downward motion of the collar 38, tube 33 and closure element 35. Means comprising a relatively resilient gasket member 46 is provided on tube 33 and in abutting relationship with the lower surface of collar 38 for sealing the aperture 34 when the tube 33 and associated parts are in the lling position. An interiorly threaded socket 47 is carried by the cap 12 for detachably receiving the rearward end of the fountain pen 37.

Fountain pen 37 includes a writing element consisting of pen nib 48 of the usual type and a feed bar 49 having a fluid and air passageway 50 in communication with the reservoir 41. Reservoir 41 is dened by barrel 51 which, on its rearward end, includes a reduced portion 52 threadedly engageable with socket 47, a tube 53 and a member 54 providing a passageway 55 which may be self-sealing. The member 54 is composed of one or more disks which are preferably formed from a relatively soft and resilient rubber or plastic which is not affected fby writing uid. The member 54 is retained in position in the barrel 51 between shoulder 56 and the downwardly extending portion of a retainer ring 57, which also supports the rearward end 58 of tube 53 which extends substantially the length of the reservoir 41 to provide a path of communication between the member 54 and the reservoir. Although not shown in this embodiment, the rearward end of the pen 37 may be provided with a barrel cap threadedly engageable with the reduced portion 52 to give the pen a pleasing appearance after being filled,

Thus, when the pen 37 needs a charge of writing fluid, its rearwardly extending reduced portion 52 is threadedly engaged with socket 47. The rearward surface of reduced portion 52 contacts the upwardly flared portion 39 of the collar 38, causing the tube 33 and the parts carried thereby to move to the lling position as shown in Figs. l and 2. The `grasping member 22 is then disengaged from the interiorly threaded projection 23 and the piston moved upwardly past uid intake 15. The container 11 is subsequently tipped toward the fluid collector 17 to obtain therein a charge of fluid which passes through iluid intake 15 and into the lower portion of the longitudinal bore 14. Piston 18 is then moved downwardly past fluid intake 15 and toward fluid discharge 16, which forces the fluid in longitudinal bore 14 to pass through discharge aperture 16, passage means, 32, inlet 29, chamber portion 27, tube 33 and tube 53 into reservoir 41. Air displaced by the entry of fluid into the reservoir normally escapes through air and fluid passage Sil in the feed bar 49. If the pen cap should be positioned over the writing element during the filling operation, however, the air in the reservoir will compress to a certain extent during ingress of fluid thereinto, and a portion thereof will then escape into the container 11 through the tube 53 and the related passageways upon subsequent upward movement of the piston. If the level of the fluid thus discharged into reservoir 41 is above the upper end of tube 53, the iuid above the upper end of the tube will be drawn back into the longitudinal bore 14 upon upward movement of the piston 18.

One of the advantages of this invention is that a predetermined amount of writing fluid can be discharged into the reservoir 41 of the fountain pen 37, this amount being determined by the capacity of the uid collector 17. Also, regardless of the number of times that the filling device is actuated, the reservoir 41 will be lled to a predetermined level, depending on the length of the tube 53 therein.

After the pen has been charged with a quantity of writing fluid, it is disengaged from the socket 47, thus allowing the tube 33, collar 38 and closure element 35 to be urged upwardly by resilient member 43 until the upper surface of closure element 35 abuts the cap 12. When the filling device is in this second non-filling position, as shown in Fig. 4, the piston 18 may be actuated without any danger of fluid being discharged from tube '33 as fluid will escape from outlet 30 through the space between the seating segment 31 and the sealing element 35.

As shown in Fig. 3, a socket closing cap 59 having a plug 68 therein may be provided to seal tube 33 from the atmosphere and to retain it and its associated parts in the filling position.

With reference to Fig. 5, there is disclosed a modified form of the device previously described. In this modified form, the lling device comprises an elongated container having the uid colletor disposed in a spaced relation with the auxiliary well and the chamber portion. vr[his modilication consists of a filling device 61 having a container 62 and a cover 63. A scalable aperture, not shown, may be provided inV either the container or the cover for lling the device with writing fluid and' for recharging it after the original supply is depleted. In addition, this lling device may include a pen receiving and storing receptacle, thus adapting it for ruse as a desk appointment.

An auxiliary well 64 having a fluid intake v72, an internal discharge aperture 68 and including pressure means as heretofore described in detail in connection with the rst embodiment of this invention, is supported within thecontainer 62 by cover 63. v A chamber portion 65having an inlet 69 andan outlet 69a is supported within container 6,2 by a support member 66 which is mounted on auxiliary well 64. Passage means 67 is provided for communicating discharge aperture 68 and inlet 69. A fluid collector 70 is disposed in a spaced relation with auxiliary well64 and chamber portion 65 in the container 62. Fluid collector 70 includes an aperture 71 which is inA iluid communication with fluid intake 72 by means ofthe tubular member 73. The cover. 63 includes an interiorly threaded socket 74` and an open ,ended hollow tube 75 reciprocal mounted thereon. The

construction and mode ofoperation of the socket 74, reciprocal tube 75 and the several parts carried thereby, is the same as in the case of the comparable parts in the heretofore described embodiment and, therefore, will not be repeated. v

When it is desired to condition this lling device for lling a fountain pen, the end carrying the auxiliarywell 64 and chamber portion 65 is tipped upwardly to cause the fluid collector 70 to be substantially filled with Writing lluid. Aperture 71 in fluid collector 70 is positioned above uid intake 72 and, therefore, the fluid in collector 70 will enter auxiliary well 64 as a result of gravity acting thereon. As with the previously described embodiment of this invention, a fountain pen is then threadedly engaged with interiorly threaded socket grasping member 76 dand the associated pressure. means anuall reci rocate mReferi'ring tu) Fig. 6, there is disclosed-a further mod ified form of the device previously described. This modification includes a relillable container 77 having a depression 78 in its lower wall. The container 77 is also provided with .a removable cap-79 threadedly or otherwise secured thereto. An auxiliary well 80 having a liuid intake 81 and a discharge aperture 82 is mounted in depression 78. A longitudinal bore`83 is also pro-v vided in auxiliary well 80, and a pressure means c omprising a piston 84 is slidably receivedtherein.

A chamber portion S5 is also received'in depression 78. This chamber portion includes an outlet 86 andl an inlet 87 which is in communication with discharge aper-l ture 82. through passage means 88. The construction and operation of tube 89, closure element 90, collar 91 and socket 92 is basically the saine asthe comparable parts described in detail heretofore in connection with the first embodiment of this invention.' However, in

this modification, a resilient member 93A is carried within" the container by the tube 89 as a 'means of limiting the upward movement of tube 89 and sealing the opening 94. In this modification, the longitudinal bore 83 1s in vdirect communication with the interior of the container 77 through fluid intake 81. Thus, it is not necessary 'tof provide a fluid collector for directing communication between the container and the fluid intake.

In its mode of'operation, this embodiment is similar to the operation of the first described embodiment and it is not felt that it is necessary to again describe it.

From the foregoing description'and the attached drawings, it will be apparent that many modifications may be made without departing from the true spirit and scope of this invention. VAs aiiexaiiipla the parts may be so 74 and the arranged that the iillingpof the reservoir is accomplished as the piston is drawn upwardly in the auxiliary well, or the slidable pressure means may be replaced by other means adapted to create a pressure on the surface of the writing uid in` the container. Also, the chamber portion illustrated in the three embodiments described herein may be eliminated vand the closure element adapted to cooperate directly with the discharge aperture in the auxiliary well. i i

It will be understood, therefore, that the invention is not to be limited to the embodiments described above, and it is contemplated, by the appended claims, to cover any such-modifications as fall within the true spirit and scope of this invention.
