19 Claims.

The present invention pertains to fountain pens and more particularly to fountain pen filling units for insertion in one end of a fountain pen barrel `adjacent the inner end of the ink intake tube.

turned to their normal position seated withinl the ends of the fountain pen barrels.

It is an object of this invention to provide a fountain pen with a filling unit engageable within one end of the fountain pen barrel and including a bulbous filling structure which is movable outwardly with respect to the barrel into a position to be actuated to cause filling of the fountain pen barrel.

It is also an object of this invention to provide a fountain pen with a filling unit insertable in one end of the fountain pen barrel and including a bulbous iilling structure which is slidably engaged over a stationary plunger unit or stem secured in the barrel adjacent the end of the fountain pen intake tube to permit filling of the fountain pen when the bulbous structure is moved into a projecting position and is manually operated by repeated transverse collapsing operations to cause filling of the fountain pen barrel.

It is a further object of this invention to provide a fountain pen with a filling unit engaged in one end'of the fountain pen barrel, said filling unit including a casing enclosing a bulbous structure, both of which are movable into a projecting position from the end of the barrel to expose spring controlled manually operable linger pieces which are operable for repeatedly collapsing the bulbous structure to effect filling of the fountain pen barrel.

It is an important object of this invention to `provide a fountain pen wherein the fountain pen barrel has a feed bar and pen point engaged in one end thereof, with an intake tube engaged in the feed bar and projecting into the barrel, while the opposite end of the barrel is provided with a filling unit normally engaged in the end of the barrel and including a bulbous lling structure which is adapted to be pulled out of the end of the barrel into a position to permit actuation of the bulbous structure and filling of the fountain pen barrel, after which the bulbous structure is pushed back into (Cl. 1Z0-46) the end of the barrel into an enclosed, protected position against operation.

Other and further important objects of this invention will be apparent from the disclosures in the specication and the accompanying drawings.

The invention (in preferred forms) is illustrated in the drawings and hereinafter more fully described.

Fig. 11 is a transverse detailed section taken on line XI--XI of Figure 10.

As shown on the drawings:

The reference numeral I indicates a fountain pen barrel which is open at both ends. Integrally formed on one end of the barrel I is a section 2, the outer end of which terminates in a threaded portion 3 on which an interiorly threaded portion of a rfountain pen cap is adapted to be threaded for holding the caprin position over the writing end of the fountain pen. For the pur-f pose of simplification, the fountain pen cap has been omitted. Projecting into the section 2 are a feed bar 4 and a pen point 5. Engaged in the inner end of the feed bar 4 is an ink intake and air tube 6 which projects axially through the ink chamber I of the fountain pen barrel to within 'a short distance of an annular shoulder 8 which is formed on the interior of the barrel I a short distance from the outer end thereof.

Engaged in the end chamber 9 of the fountain pen barrel I is one form of an improved filler unit comprising a stationary plunger or tube I0 provided with an axial passage Il, the inner end of which continues through a base plate or disc I2 which tightly seats against the shoulder 8 of the fountain pen barrel I. The peripheral surface of the plate I2 is in tight frictional sealing contact with the wall of the chamber 9 of the fountain pen barrel. Integrally formed on the outer end of the passaged stem IIJ is a retaining head I3 which is centrally apertured with the aperture registering with the passage Il of the tube I0. The tube I0, together with the plate I2 and the head I3 may be constructed of hard rubber or other suitable material.

slidably engaged over the stationary stem I0 and over the head I3 formed on the outer end thereof, is a filler device comprising a bulb or bellows I4 constructed of rubber or other suitable material and enclosed by a reinforcing or stiffening sleeve or covering I5 which may be glued, cemented, or otherwise secured around the exterior surface of the bellows or bulb I4. Secured in the inner end of the bulb I4 is a centrally passaged or apertured closure disc or bushing I6 constructed of hard rubber or other suitable material. The bushing I6 is slidably engaged over the stationary stern I 0 and is adapted to contactthe inner face of the stem head I3 when the filling device is in its outermost position, as illustrated in Figure 2, to limit the outward movement of .said filling device. The outer end of the bulb or rubber casing I 4 is closed by means of a centrally apertured disc or bushing I1. Secured over the outer end of the bulb I4 and its cover I5 and'also enclosing the gasket I'I, is a metalnishing cap I8. The filling device in its normal closed position projects into the end of the fountain pen barrel chamber 9 to close the end of the barrel. Rigidly secured to the cap I8 and tothe bushing I1 is a button or knob I9 which is so formed that a groove 20 is provided between the head of the button I9 and the outer face of the cap I8 for the reception of the fingernails of a persons hand when it is desired topull Vthe filling device out'- Wardly from the normal position illustrated in Figure 1 into the fullV line position of Figure 2. When the filling device is in the outermost position illustrated in Figure 2, it is only necessary4 to project the feed bar 4 and the pen point, 5 into a supply of ink and then manually, repeatedly compress and release the bulb or rubber case I4 to cause ink to be drawn upwardly through the ink intake tube 6 to be deposited in the ink chamber 'I of the fountain pen barrel to fill the fountain pen.

Figures 4 and 5 illustrate a modified form of filling unit which consists of a stem unit constructed the same as the stem unit illustrated in Figures 1 and 2, and which is mounted to remain stationary within the chamber 9 of the fountain pen barrel I with the base plate I2 seated against the shoulder 8. The filler device portion of the filling unit comprises a diametri- `cally compressible rubber bulb or casing 2| which is closed at its outer end by an integral top 22 which is of diameter greater than the top end of the bulb 2|. Projecting into the bottom surface of the projecting portion of the closure top 22 are the upper ends of a plurality of metal strap springs 24 which extend downwardly in spaced relation around the bulb ZI and have the lower ends thereof projecting into a base, 25 integrally formed on the lower end of the bulb 2|. Engaged around the bulb 2| and the strap springs 24 thereof is a metal mesh protecting covering or casing 26, the ends of which engage around and are secured to the bulb top 22 and the base 25. Securely engaged over the outer end of the mesh covering 26 and the top 22 of the bulb is a metal finishing closure cap 21 which normally is adapted to seat in the end of the chamber 9 of the barrel I to close the same. Secured on the cap 21. is an operating button or knob 28, which serves as a linger piece for moving the filling device from the position illustrated in Figure 4 into an outwardly projecting position similar to that illustrated in Figure 2 to permit alternate compression and release of the bulbous structure 2I within the protecting metal mesh housing 26. With the outward movement of the bulbous structure 2l and its covering, the stem unit I0 remains stationary Vwithin the barrel I with the stem head I3 acting as a stop for limiting the outward movement of the bulbous filling mechanism.

`Figures 6, 7, and 8 illustrate still another modified form of fountain pen filling unit consisting of` a slidable filling device associated with a stationary stem mechanism secured within the fountain pen barrel. 'Ihe parts which are simi-.

lar to those illustrated and described in connection with Figures 1 to 3 inclusive are correspondingly numbered.

Slidably engaged in the barrel chamber 9 in telescoping relationship with the stationary stem III is a filling device comprising a bulb or bellows 29 constructed of soft rubber or other suitable material which is closed at its upper or outer end by means of a cap or cover plate 30. Integrally formed on the lower or inner end of the bulb 29 is a passaged base or bottom plate 3I- which .slidably engages overthe stem I0 with the stem head I3 positioned inside of the bulb 29. Secured over the bulb 29 is a metal protecting casing. 32 having finger openings orl windows. 33 provided in op-posite sides thereof to permit access to be had to the sides of the bulbous structure for compressing the `same for filling. the fountain pen. The` upper end of the protecting casing 32 is closed and has secured or formed thereon a inner end of the protecting casingl 32 is open'and engages around the base 3l of the bulb 29.

Figures 9, 10, and 11 illustrate another modified form of fountain pen filling unit in which the stem mechanism is omitted and wherein the outer end of the recess or chamber 9 of the fountain pen barrel l has a metal stop sleeve 35 secured therein for limiting the outward movement of the fountain pen filling unit, which normally is seated against the stop shoulder 8 in the barrel l, as illustrated in Figure 9.

'I'he filler unit comprises a metal tube or casing 36, provided with diametrically opposite longitudinally disposed openings or slots 31. The outer end of the casing 36 is closed by means of a top plate or plug 38 having a button or knob 39 formed on the outer side thereof. The inner end of the casing 36 is closed by means of a base `plug 40 having an axial passageV 4l provided therethrough. The base plug 40 is provided with a shoulder at 42 whichis adapted to seat against the end of the stop sleeve 35 to limit the outward movement of vthe filler unit when the same is moved into an operating position, as illustrated in Figure 10. The inner end of the base plug 40 is circumferentially grooved to provide a shank portion 43 around which the open end of a filling bulb or bellows 44 is secured. The bulb 44 projects upwardly into the casing 36 between a pair of oppositely positioned actuating bars or plates 45 disposed within the casing 36. Each of the plates 45 is provided with a finger piece or ear 46 which projects outwardly through one of the slots 31 in the casing 36. The bulb 44,which is constructed of rubber or other suitable material, normally acts on the plates 45 to project the finger pieces 4B outwardly through the slots 31 into an actuating position, when the filling device is pulled into its outermost operating position as shown in Figure 10. When the filling device is projected into the chamber 9, as shown in Figure 9, the projecting finger pieces 46 cominginto contact with the stop sleeve or collar 35 are projected into the sleeve or casing 36 thereby causing'the actuating plates 45 to compress the bulb 44 when the filler device is not in use. y

To fill the fountain pen, it is only necessary to engage the knob 39 topull the casing 36 from` the position illustrated in Figure 9 into the projecting position shown in Figure 10, in which position the resilient bulb 44 acts to project the actuating finger pieces or ears 46 outwardly through the slots 31, so that when the finger pieces 46 are compressed and released, the filler bulb 44 is compressed and released thereby causing ink to be drawn upwardly through the ink intake tube 6 to fill the fountain pen.

It will, of course, be understood that numerous details of construction may be varied through a wide range without departing from` the principles of this invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
