Application. May ,22, 1M5, Serial .No 595,106 1 Claims.
This" invention" relates to" fountain pens 'in whichink is used as the writing fluid.
Th'e'object of my invention is to make a fountain; pen. Which is provided with an insertible ink container" that can instantly be removed wherrempty andlbe replaced with a new ink corrtainer-which' has been filled with ink at the container factory;
In this connection thenew fountain pen is, intitspen-point holding stem provided with a specially" developed fiowand prick-pin, which is required as an essential mechanical part to function with the insertible ink container.
Toenableoth'ers'; skilled inthe art, to fully comprehend" the" underlying features of my invention; drawings depicting" a preferred'form have been annexed as a part of this disclosure andin" these drawings similar reference characters denotecorresponding parts throughout theseveral views, of which:
Fig: 1 isa vertical section of the insertible ink container, connectedto the-fiowand prick-pin inthe pen-point holding stem and positioned inside the'pen housing, with the locking-cap on top, in place.
Fig. 2 is a vertical cross section illustrating the filling'plugandthe sealing disc with the sealing skin or membrane implace between them prior to assembly in the ink container casing.
Fig; 3 is an enlarged fragmentary vertical cross section showing the sealing skin or membranepierced by the prick pin.
Fig. 4 is a detail side elevation illustrating the ink container" removed from the-pen easing;
Referring'nowto the drawing whereinlike reference characters denote corresponding parts throughout theseveral-views, 3' designates in its entiretythe fountain pen housing that is attachediito the penepoint'h'olding: stem 4 andiin whichth'e newly developed iiow and prick-pin 5'.is'securely locked by the aid offathreadand'a shoulder. rest:
After 'thetrubberi bag: 6* isfastened tothe neck of theifilling plug "I, the ink'istpouredfintoithe rubber bag through the center; opening 3; shown in Fig. 271i. the threadedfilling plug T and is thenlet into'the stifi'casingil, whence itis; by thelaid oi a pin-key which:fits*ho1es34; screwed in: as arias it will go on the threads provided for inside the :casing "9.
Next the sealing disc ill; with. itsedrumtaut sealing skin I! cemented thereon is, by the aid of azpinkey WhiCh"fitS holes'M, screwed into the end opening'oicasing 9, sorthatthe sealing skin I I is pressed tight against the 'top'suria'ce of I the plug 'l'.
As soon as this is done, the opening 8 in plug 'I'becomes sealed, so. thattthe ink, contained in bag 6 cannot spill out.
As a safeguard against leakage theathreads of 2'. plug/I and sealingdisc- I9 should be covered with asuitablefiuid cement, which ink cannot "dis-'- solve, before they are screwed into place iii-the threaded end opening of easing 9.
Some time must be allowed for the sealing ceinentfin the'threads'to dry before the insertible ink container is put in circulation and use."
However, in order to prevent any loosening of the sealing disc IS in its threads when positioned in the casing s; which, in eiiect would mean'a relaxing ofthe pressure applied to theseal'ing skin H against the plug" I, it is suggested,- to peen' the most extreme end of the-casings overa' little as indicated att so'that unscrewing'of the disc 1c is made impossible; veither in'handling while in'the assembly stages or later on in packing and shipping.
An inverted cupped washer i2 is'laidon" top of the sealing disc Ill-and the conical ended soft rubber pad I3 "is dropped'in position into the'hollowed opening IQ of the sealing disc I92 An all-around closexfitting cupped washer I5, which williprevent the rubberpad from spreading at the circumference is now laid on top of thesoft rubber'pad' I3 and finally the threaded cap i E is screwedonto theoutsidethreads'on'the end of the casing 9.
The insertible ink container isnow completely assembled and can'be' inserted into the penhousing 3 with its attached pen-point stem 4 and in it the centrally located fiowand prick-pin 5.
The outside diameter of the threaded cap I6 is such that it has a perfect sliding fit inside the housing 3, so that the insertible ink container is located absolutely central inside the housing 3.
In order to steady the descent of the insertible ink container in the housing 3 still more, circular bulges I8 are'provided in the walls-of the casing 9 at several points throughout its-entire length; which will make it absolutely sure that the descent of the ink container in the housing 3 takes 'placeas centrally as possible andxforthat reason the outside diameter of thebulges IBImust be exactly the same as that of the threaded 08,13 .16.
The bulges i 8 can alsobe arranged .to runvertically or spirally-on the outside. of the :casingzfl.
It is desirable that the needlepointl'lofithe flowand prick pin E pierce-the. sealing skin; II as exactly in the center as canpossiblyibe' ob?- tained When the needlepoint II pierces thezdrawn taut sealing skin I I, the conicalienlargement'ifrom the prick-point on down, will, as it enters higher into-the ink reservoir, also enlarge the. sealing skin hole, until finaliy the periphery of the-circular step collar 29 0f the flowandpricki-pin 5, pushes, what is leftof the sealing skin, tightly into'the recess 3:], provided for thisrpurpose in berhind'ere'd to run into'theside hole-'2 I andfrom there towards the pen point through the center hole 30 inside the fiowand prick-pin 5. Leakage drain holes are provided in equidistantly spaced relation about the prick pin, one row 32 of such holes being provided in the collar 22 and another row 33 of such holes being provided in the conical section 22.
The thick rubber pad l3 presses tightly against the conical section 22 and the straight shank sides 23 of the fiowand prick-pin 5, so that any lea age of the ink is out of the question.
The threaded end cap l adjusts the pressur of the soft rubber pad [3. It is set in the factory and is sealed.
The conical surface 24 in the filling plug 1 permits the ink to flow to the last drop on the fiat of step collar 20, which fiat surface is slightly tapered toward the entrance to the side hole 2 I, so that the ink must fiow towards the hole 2| and this hole again is slightly tapered towards the center hole 30 inside the fiowand prick-pin 5.
Naturally, like all thin fluids, the ink will flow quickly towards the lowest point, so that, when no more ink is coming to the fountain pen point to even put a dot over an i, it can readily be assumed, that the insertible ink container has been completely emptied of the ink it contained.
Although fibre and plastics material can be used for the casing 9, it is however preferably made from thin metal tubing, which is threaded at one end for the plug 1 and disc I!) as well as the end cap [6 and is threaded also at the opposite end for the shoulder cap 25, which is provided with an extended knob 26 that serves as a handle to pull the empty ink container out of the pen housing 3.
Over this pull handle cap is provided an auxiliary knurled cap 2! which screws into the upper open end of the pen housing 3 to hold the insertible ink container securely seated in its socket of the rubber pad l3 and lock its position by the applied pressure of the flat surface 28 onto the swivel washer 29 which is fastened to the top of the pull knob 26 by the shoulder screw I9.
The empty ink container is best removed by laying the pen fiat on a table in such a position that the hand can grip the pull knob conveniently with two fingers and holding the pen on the table with the other hand, a slight, short jerk on the pull knob will remove the empty ink container easily.
Insertion of a new ink container may be accomplished with facility by resting the pull knob end on a table and, with the ink container held in an upright position by one hand, using the other hand to slide the pen housing over the ink container until the housing is about two-thirds over the ink container.
The hand that holds the ink container can now let go of it and grip instead, with a few fingers, the housing, and, together with a few fingers of the other hand, give a short jerk downward, until it is felt it cannot go in any farther.
Now the knurled locking cap 21 is screwed onto the housing over the pull handle knob 26 and the pen is ready for use.
It will be apparent by reference to Figure 1 that the prick pin 5 has a flange enlargement just above the threaded lower end portion 31 thereof which presents a fiat upper surface 36 serving as an end stop for the inserted ink container.
In regard to the drawn taut sealing skin ll, connected to disc I0, it should be explained, that a chosen flat surface of disc I1 is coated with cement and on this cement coated disc surface is laid an oversize piece of highly stretchable fiawless thin rubber sheet.
The disc Iii, being held in a fixture which is fastened securely to a bench in a work shop, is now immovable and While in this state the oversize thin piece of rubber sheet lying on the cement coated disc surface, is now by mechanical means especially designed for this purpose, stretched uniformly in all directions and with somewhat of a side-pull over the edges of disc iii to a predetermined stop.
Now a clamping device is fastened on top of this highly stretched piece of thin rubber sheet lying on the cement coated surface of disc l0 and is at last laid aside for drying for a predetermined period.
When completely dry, the clamp is removed and the overhanging rubber sheet trimmed off, so that the threads on the periphery of disc H] are free and clear to enter the threaded end of casing 9.
This taut stretched rubber skin H on disc 10, will, when pierced by the point IQ of the flow. and prick-pin 5, recede with a snap to the very edges of the opening 8 in plug 1 in such a manner that only a very small circular ridge remains of the rubber around the edges of the opening 8 in plug 1.
This small ridge of rubber skin is finally pushed into the recess 3! of plug 1 by the step collar 20 as the conical fiowand prick-pin pushes into the ink reservoir.
While the pen housing 3 is held very snug on the neck 2 of the pen point holding stem 4, it is advisable in this case to provide a number of countersunk screws l around the circumference as a safeguard, so that the housing cannot slip oii the neck 2 when the empty ink container is pulled out. A cap over the pen point is provided.
Although I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrange- .ment of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.
