Description
J. B. CARR FOUNTAIN PEN Aug. 25, 1942.
Filed Feb. 27, 1942 Patented Au 25, 1942 2,294,070 FOUNTAIN PEN John 8. Can, Water-town, N. Y. Application February 2'1, 1942, Serial No. 432,695 1 Claim. (Cl. 120-42) My invention relates to improvements in fountain pens.
Theinvention is designed with the principal object in view of providing a simply constructed fountain pen adapted for loading with a refill cartridge to be supplied by the trade sealed for insertion in the pen, and to equip the pen with practical and reliable means for puncturing the cartridge as it is forced home in the pen so that the contents thereof may feed therefrom in writing.
Another object is to provide a pen equipped for utilizing a refill cartridge and which will not leak or get out of order and which is inexpensive to manufacture. Other and subordinate objects are also comprehended by my invention, all of which, together with the, precise nature of my improvements will be readily understood when the succeeding description and claim are read with reference to the drawing accompanying and forming part of this specification.
In said drawing:
Figure l is a view in longitudinal section of a fountain pen embodying my improvements,
Figure 2 is a view in transverse section taken on the line, 2-2 of Figure 1 and drawn to an enlarged scale, 1
Figure 3 isa similar view taken on the line 3-3 of Figure 1, and
Figure 4 is another similar view taken on the line 4-4 of Figure 1.
Referring to the drawing by numerals, my improved pen, in its preferred illustrated embodiment, comprises a barrel I having threaded into the leading end thereof a pen and feeder tube holder 2 of the usual type with the following exceptions:
The inner end of the holder 2 is provided with an inwardly tapering seat 3 at its inner end and the feeder tube 3' with an internal spider 4 adjacent its inner end. The spider 4 has threaded therein axially ofthe feeder tube 2 a relatively smaller stem 5 of apuncturin'g member including a sharp pointed head 6 fast on the inner end of the stem and projecting axially of the feeder tube 3' beyond the inner end thereof. The puncturing member, as regards the head 6,
axial annular flange I3 is provided on the outer face of the cap plug l2 which forms a socket therein.
The rear end of the barrel l is reduced and exteriorly threaded to receive a thimble-llke closure cap piece l4 turned thereon and having an internal axial stem l5 fitting in the flange l3. The cartridge 8 and the stem l5 are of a. length such that when the cap piece I4 is turned home, the stem l5 bears against the cap plug I2 and forces the front end of the cartridge tight against .the seat 3 and feeder tube 3'.
In loading the barrel l with the described cartridge, the cap piece II is first removed and the cartridge slid into the barrel l front end leading. The cap piece H is then turned home and under this operation the stem l5 forces the cartridge 2 forwardly and its nose Ill against the head 6 of the puncturing member so that the nose is punctured to provide a discharge aperture therein through which the ink may fiow into the feeder tube 3'.
As will be understood, the cartridge 8 is designed to be sealed in any suitable manner for sale and constructed so that when once punctured it cannot be refilled and must be replaced. The described puncturing member may be unscrewed and replaced in a manner which will beobvious.
The foregoing will, it is believed, suffice to impart a clear understanding of myinvention without further explanation.
Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scape of the subjoined claim.
What I claim is:
In a fountain pen a barrel, a pen and feeder tube holder detachably secured in one end of said barrel and having a tapered socket in the inner end thereof, a puncturing member extending out of said tube into said socket, anink containing cartridge slidably fitted in said barrel and having a tapered front end for fitting in said seat and to be punctures by said member by sliding of the cartridge in the barrel toward said member, a cap threaded onto the other end is, generally speaking, of arrow-head form with blades 1 arranged in 90 degree angular relation.
An ink containing cartridge 8 is provided which is of the proper form to fit in the barrel l and which is constructed with a tapering front end 9 fitting against the seat 3 and terminating in a flat nose l0 fitting against the inner end of the feeder tube 3'. The rear end of the cartridge 8 is internally threaded, as at II, and closed by a shouldered cap plug I2 turned therein. An
of the barrel for turning onand off the same, and means to cause sliding of said cartridge toward said member by turning of said cap onto said other end of said barrel, said tube having a diametrical spider therein and said member comprising a stem detachably secured in said spider and provided with an enlarged pointed head including cutting blades having converging cutting edges.
JOHN B. CARR.
