FOUNTAIN PEN A ril 19, 193.
Filed Jan. 27, 1957 WITNESSES INVENTOR 4M Ign Q23 8 Q25 2 I BY ATTORNEYS Patented A r. 19, 1938 UNITED;- STATES PATENT OFFICE 7 Claims.
This invention relates to improvements in fountain pens and it is an object of the invention to provide a fountain pen with improved means whereby ink or writing fluid can be produced in the reservoir of the pen. by means of a solvent such as water, and anink stick, cartridge, or pellet.
It is a further object to provide an improved fountain pen of the above type in which the ink I stick, cartridge, or pellet is held transversely of the fluid passage beneath the reservoir of the fountain pen so that it will readily dissolve in the fluid to produce ink or the like, and the ink stick is partially encased so as to prevent it from E completely disintegrating and clogging the feed duct leading to the nib.
Another object is the provision in a fountain pen of a removable stopper or closure in association with a perforated tube to receive the ink pellet or the like, whereby a new ink pellet may without difficulty be deposited. in the pen and which is formed so that it will not leak and Will not interfere with the proper operation of the feeding or filling mechanism.
In the accompanying drawing:-
Fig. 1 is an elevation partially in section of a fountain pen embodying my invention;
Fig. 2 is a. sectional view on theline 2-2 of Fig. 1;
Fig. 3 is a side View in perspective of the re- 'movable perforated tube and stopper for holding the ink pellet, stock, or cartridge; and v Fig. 4 is a View of one type. of ink stick or the like which may be used in association with. my apparatus.
My invention may be used in association with any desired style or design of fountain pen but is particularly suited for use with fountain pens of the self-filling, rubber sac type. In the accompanying drawing it is illustrated in association with one of the standard types of rubber sac, self-filling fountain pens but it is to be understood that other types of pens may be employed.
The numeral it) represents the pen or nib which is provided with a feeder having a feed and air duct l2 of the usual type provided therein whereby ink may be drawn into the filling sac and will automatically feed to the point of the pen when the pen is in use. The nib and feeder are secured in the usual manner in the section It, which is circular in cross section and tapers slightly towards the lower end where an enlarged collar portion is 55 provided, all in the usual manner. The upper portion of the section is of slightly reduced diameter so as to receive the lower end of the barrel l5, which is externally threaded as at I6 adjacent its lower end so that the cap I! may be secured 60 thereto. The cap is of usual construction and may be provided with a clip l8 and ornamental bands I9;
At its upper end, the section M is provided with a shank of reduced diameter to which is secured the lower end of the sac 2|, which is preferably formed of rubber or similar non-porous, resilient material which when compressed and released will create sufficient suction to draw fluid into the sac and retain it therein. The side of the barrel is slotted in the usual manner as at 22, so as to receive the filling lever 23, which is pivoted as at 24 to the barrel. The lower end of the lever 25 extends below the pivot 24 so that when thehan-dle 26 at the upper end of the lever is pivoted outwardly the portion 25 will project inwardly engaging the metal strip 2'8, which is secured inside the barrel in the usual manner, thereby forcing it inwardly and causing it to compress the rubber sac 2|. A fluid passage 28 in the section lfl affords communication between the 'sac and' feeder ducts.
The mechanism heretofore described is one well-known type of rubber sac, self-filling fountain pen and is operated in the usual manner. Thus when the upper end 26 of the lever 23 is pivoted outwardly it will compress the sac forcing the contents thereof outwardly through the fluid passage 28 provided in the section l4 and. the feed duct l2. If the nib and feeder are inserted in a fluid and the lever 23 is returned to the position shown in Fig. 1, the rubber sac will slowly return to its normal position drawing the fluid upwardly through the feed duct l2, fluid passage 28, and thence into the sac, all in the usual manner.
So that writing'fluid may be formed inside the pen by means of an ink pellet or the like, and a solventfor the pellet, I provide an opening in the side of the section formed. so as to receive a perforated tube or the like for holding the pellet transversely of the fluid passage 28 beneath and adjacent to the rubber sac.
In carrying out my invention, I prefer to provide the section It with a recessed portion indicated at 30 in its external surface a short distance below the lower end of the barrel l5. Extending inwardly from the recessed portion through the wallof the section, I provide an opening or bore 3| which communicates internally with the fluid passage 28. Opposite thev bore 3| the inner wall of the section may be provided with a recess 32 for receiving the end of the perforated tube as will be later explained.
I also. provide a removable member which serves. not only as a, closure for the bore or opening. 3|, but also as a casing for retaining and holding in proper position an ink pellet, ink stick, or the like. This member may consist of a tube 33 of sufficient length to extend through the opening 30 transversely of the fluid passage 28, and
into the recess 32 in the opposite wall. At its outer end the tube 33 is preferably provided with a cap 34 of slightly enlarged diameter so as to engage the outer surface of the wall surrounding the opening 3!. The tube 33 and the cap 34 serve together as a closure for the duct or bore 3|. The tube 33 also serves as a casing for the ink pellet or ink stick, and in order that the fluid in the pen may come into contact with the ink stick or pellet and cause it to dissolve and form ink or similar writing fluid, the tube should be provided with a plurality of perforations, such as are indicated at 35, and of which there may be two, four, or even more in number.
In using my pen the perforated tube 33 is withdrawn from the opening in the section. This may be conveniently accomplished in view of the provision of the enlarged head 34, which enables the insertion of an instrument or the finger nail beneath the head. When the tube has been removed as shown in Fig. 3, an ink stick or pellet 36 of the type shown in Fig. 4 may be inserted through the open end thereof and the tube is then replaced in the opening 3| so as to extend transversely of the fluid passage with the open end thereof projecting into the recess 32 as shown most clearly in Figs. 1 and 2. The pen may then be filled with a suitable fluid solvent for the ink stick or pellet, such as water, in the manner heretofore described. The water or other fluid will enter through the perforations 35 in the tube causing a portion of the ink stick or pellet to dissolve and thereby produce ink or similar writing fiuid.
From time to time as the fluid in the pen is exhausted it may be filled with a new supply of fluid; likewise, when the ink stick or pellet becomes completely dissolved a new stick or pellet may be conveniently inserted in the pen by removing the tube 33 as described above. If the tube 33 is removed while there is fluid in the pen, the pen should be held in inverted position with the nib pointing upwardly so as to prevent leakage of the fluid outwardly through the duct or opening 3 I. A single supply of ink stick or pellet should last for several fillings with fluid and in that way my improved type of pen is very economical to use.
The perforated tube 33 serves not only as a holder for the stick or pellet, holding it in proper position to be dissolved, but also as a protective casing to prevent it from becoming disintegrated and thereby clog the filling and feeding duct of the feeder. By projecting the open end of the tube into the recess 32, it is effectually held in proper position and the pellet can not escape therefrom. When the tube is formed in the manner shown in the accompanying drawing, it should have tight frictional engagement with the sides or walls of the duct 3| so as to prevent leakage. Instead of this type of construction, however, I may thread the tube into the opening, or, if desired, may have the tube permanently secured in the opening, and provide it with a removable cap which is threaded or otherwise suitably secured in position.
It will be seen by the foregoing description of one illustrative embodiment of my invention that I have provided an improved fountain pen which is provided with removable means in the section portion whereby an ink stick or pellet may be inserted inside the pen and will be held transversely of the fluid passage so that it can be dissolved by a suitable solvent so as to produce ink or other writing fluid. It will also be seen that by means of my invention the ink stick or pellet may be conveniently replaced with a new supply and that the removable means does not leak, nor does it in any way interfere with the proper operation of the pen or the feeding and filling mechanism.
It should be understood, of course, that modifications may be made in the illustrated and described embodiment of my invention without departing from the invention as set forth in the accompanying claims.
I claim:
1. In a self-filling fountain pen, a removable perforated tube disposed transversely of the section above the feeder for holding an ink stick or the like.
2. In a fountain pen of the sac-filling type, a section providing a fluid passage between the sac and the feeder, said section being provided with an opening in one side thereof communicating with the fluid passage, and a removable perforated tube disposed in said opening and extending transversely of the fluid passage, said tube serving as a closure for the opening and also being co-operable for holding an ink pellet or the like in the fluid passage so as to communicate with the fluid supply.
3. The combination with a self-filling fountain pen having a rubber filling sac, a feeder and a nib, and a section providing a passage between the sac and feeder, of a perforated tube mounted in the section transversely of the passage.
