Description
Patented May 6 1941 FLUID DISPENSING APPARATUS Hans H. Berger, Los Angelcs, Calif., assignor to The McCass Company, Los Angeles, Calif., a corporation of California Application October 25, 1939, Serial No. 301,215
8 Claims.
My invention relates to fluid dispensing apparatus and particularly to a device in which the fluid dispensed is contained in a sealed cartridge. The present invention is herein illustrated and described in the form of a fountain pen adapted to receive a sealed cartridge containing ink and in which means is provided for automatically establishing communication between the cartridge and the pen point.
Most of the fountain pens in use utilize various forms of mechanisms for supplying ink to the barrel or bulb of the pen body. Such pens are subject to wear, leakage and deterioration and often fail to properly feed ink to the pen point.
An object of my invention is to provide a fountain pen in which the ink supply is obtained from a sealed cartridge disposed within the pen body. A further object of this invention is to provide a novel means for automatically piercing the sealed capsule upon the insertion into the pen body and to simultaneously force ink from the cartridge to the point of the pen. A further object of my invention is the provision of such a pen in which novel means is provided for sealing certain portions of the cartridge with the pen body in order to prevent the flow of ink in any direction but to the point of the pen. Still another object of this invention is to provide a novel means of forcing an ink-filled cartridge against a piercing member within the pen body.
Another object of my invention is to provide a fountain pen employing the use of a sealed cartridge in which an empty cartridge may be readily removed from the pen body. o
Other objects and advantages will become apparent in the following description taken in connection with the accompanying drawing in which:
1 is an enlarged, longitudinal, sectional view through a preferred form of fountain pen of my invention.
Fig. 2 is a view similar to Fig. 1 showing the initial step in the insertion of a cartridge into the pen body. I
Fig. 3 is a view similar to Figs. 1 and 2 showing the final step in the insertion of a cartridge into the pen body.
Fig. 4 is a transverse, sectional view taken on the line 4-4 of Fig. 1 and Fig. 5 is a detailed perspective view of a cartridge-piercing member employed in the apparatus of my invention.
Referring specifically to the drawing a fountain pen 10, comprising a preferred embodiment of my invention, includes a tubular body ll hav- .is a duct communicating with the bore I! or capillary system of the member [5 for the purpose of supplying ink to the pen point IS in a manner to be described hereinafter. Provided within the body ll adjacent to the plug I2 is an annular resilient gasket 22 formed of rubber or the like. As seen in Fig. 3, a gasket 22 is slightly tapered and formed to provide an annular shoulder 23 at one end thereof. Threaded on to the body II is a cap 25.
Slidable into the body II is a cylindrical cartridge 28 the latter containing a supply of ink 29 provided within the cartridge 28. In practice the body H and the cartridge 28 are preferably made of translucent material so that the supply of ink within the cartridge 28 will be visible.
The cartridge 28 is inserted into the body II by removing the cap as seen in Fig. 2, the
' cartridge 28 is then forced against the member,
I 5 and, as seen in Fig. 2, the gasket 22 comes into sealing relation with the extremity of the cartridge 28 as the latter engages the pointed head l8 of the member l5. At this point the cap 25 is threaded on to the body H thus forcing the cartridge further into the body ll causing the head l6 of the member l5 to be forced through the end of the cartridge thus establishing communication bctween the interior of the cartridge 28 and the duct 20 as seen in Fig. 3. When the cap 25 is completely threaded on to the body II, as seen in Fig. 1', the extremity of the cartridge 28 is forced against the shoulder 23 of the gasket 22 and the head It of the member I5 is disposed well within the pierced end of the cartridge 28. The amount of ink displaced by the head I 6 is sufficient to fill the bore I! of the member l5 and the duct 20 of the plug l2 thus delivering ink immediately to the tip ofthe pen point I3. The non-circular shape of the head I 6 permits the passage of ink from the cartridge 28 into the duct 20 about the head I6 as Well as through the bore l'l'of the member l5 thus insuring an ample supply of ink to the pen point.
The cartridge 28 may be readily removed from the body I l by removing the cap 25 and grasping the portion of the cartridge 28 which extends cylindrical,
beyond the body II and then drawing the cartridge 28 from the body II.
It is thus seen that the fountain pen I!) of my invention is extremely simple in construction and operation and insures a free supply of ink at all times while effectively preventing undesirable leakage of ink.
Although I have shown and described but one preferred embodiment understood that various modifications and changes might be made therein without departing from the spirit of of the appended claims.
